Barbero
The barbero is one of a family of fishes commonly
called surgeon-fish.

Barbero (SS-317); dp. 1526; l. 311'9"; b. 27'3"; dr. 16'10"; s.
20.3 k.; cpl. 66; a.15", 10 21" TT.; cl. Balao)

Barbero (SS-317) was launched 12 December 1943 by
Electric Boat Co., Groton, Conn.; sponsored by Mrs.
Katherine R. Keating; and commissioned 29 April 1944,
Lieutenant Commander I. S. Hartman in command.
Barbero's war operations span the period from 9 Au-
gust 1944 until 2 January 1945, during which time she
completed two war patrols. She is officially credited
with sinking three Japanese merchant ships totaling 9126
tons while patrolling in the Java and South China Seas.
On 27 December 1944, enroute to Fremantle, Australia,
Barbero, while at periscope depth, received an aerial
bomb close aboard aft. This near miss damaged the port
reduction gear and put Barbero out of action for the re-
mainder of the war.
In September 1945 she was ordered to Mare Island
Navy Yard where she underwent pre-inactivation overhaul
and was placed in commission in reserve 25 April 1946.
Following conversion to a cargo submarine (reclassified
SSA-317, 31 March 1948) at Mare Island, Barbero was
recommissioned 28 July 1948 and assigned to the Pacific
Fleet. Between October 1948 and March 1950 she took
part in an experimental program to evaluate her capabili-
ties as a cargo carrier. Experimentation was discontin-
ued in early 1950 and she went out of commission in
reserve 30 June 1950.
On 1 February 1955 Barbero entered Mare Island Naval
Shipyard for her second conversion. Her designation
was changed to SSG-317 (Guided Missile Submarine) 25
October 1955 and she was recommissioned 28 October
1955. She operated off the coast of California until April
1956 when she transited the Panama Canal and joined
the Atlantic Fleet.
Barbero received two battle stars for her World War
II service.

(A) PROLOGUE.

        Commissioned in U.S. Navy as U.S.S. BARBERO (SS317), at Submarine
Base, New London, Conn., on 29 April 1944. Conducted training exercises
and trials in Block Island Sound and Long Island Sound areas. Departed
New London, Conn., on 5 June 1944 to join the Pacific Fleet. Stopped at
Key West, Florida for a ten day period rendering services to the Fleet
Sound School. While at Key West, ship was dry-docked to repair two leak-
ing air bottles in main ballast tanks. Arrived Pearl Harbor on 15 July
1944. Conducted final training exercises out of Pearl Harbor.

(B) NARRATIVE.

9 August 1944.

        1330 VW    Departed Pearl Harbor enroute area via Midway Island in
                   company with escort U.S.S. PC-485.
        1945 VW    Released escort.

10-12 August 1944.

                   Enroute Midway conducting training dives and exercises.

13 August 1944.

        0813 Y     Moored along side pier at Submarine Base, Midway Island.
                   Fueled and provisioned to capacity. I had intended to get
                   underway at 1530 Y but repairs to SD radar required an ex-
                   tension.

14 August 1944.

        1000 Y     Underway enroute area. Manufacturers technician at base
                   stated that SD radar was working as good as the average.
                   Ship's personnel unanimously agreed that it was not right.
                   The sweep was jumping all over the screen. Upon depart-
                   ure entrance buoys with many planes in sight not a single
                   pip could be obtained. Proceeded.

15 August 1944.

                   Omitted due to crossing of international date line.

22 August 1944.

    0918 K    Sighted friendly search plane (Martin Mariner) on port
              bow. (Aircraft contact No. 1) After crossing bow, plane
              turned towards, circled us at about 2,000 yards, and pro-
              ceeded northward.
    1218 K    Submerged on sighting plane coming in on starboard beam.
              (Aircraft contact No. 2) After submergence identified
              plane as PBM, probably the same one sighted going north
              this morning.
    1229 K    Surfaced and identified ourselves to plane with signal
              rocket.

23 August 1944.

    0840 K    At Lat. 21-32 N., Long. 139-38 E., lookout sighted peris-
              cope about 1,000 yards on starboard beam. Swung left and
              cleared area at flank speed. Sighting was made by Chief
              of the Boat but not otherwise confirmed.

24 August 1944.

    0700 I    Entered area. Set course to make landfall on east coast
              of Luzon in the vicinity of Palanan Point.

28 August 1944.
1453 H Submerged 24 miles northeast of Port Anajao on Catanduanes
        Island and set course to southward.
1830 H Surfaced continuing southward to San Bernardino Strait.

29 August 1944.
0330 H Sighted Ungay Point bearing 265° T, distance 18 miles.
0345 H Received 147 megacycle radar signal on APR, signal inter-
        mittent.
0446 H Submerged 18 miles east of Ungay Point proceeding south-
        ward.
1838 H Surfaced and set course to eastward exploring the area.

30 August 1944.
0500 H Made SD contact at 18 miles. Submerged. Had intended to
        patrol on surface east of Batag Island but in view of ex-
        cellent visibility and proximity of land decided to remain
        submerged and close to Batag Island.
1838 H Surfaced and stood northwest towards Catanduanes Island.

31 August 1944.
        Spent day submerged off entrance to Albay Gulf.
2248 H At a point 15 miles northeast of San Bernardino Light
        headed southward to investigate possible contact in the
        strait.
2250 H Sighted small craft on bearing 190° T. Unable to make out
        its characteristics. Radar came through with a range of
        2,700 yards closing.
2254 H Submerged to investigate small craft. Unable to identify.
2308 H Surfaced and manned automatic weapons pursuing small craft
        towards San Bernardino Straits.
2326 H As target was definitely heading for the Straits and had
        an extremely poor background for gun fire, its enemy
        character not definitely known and not desiring to get
        tangled up in the shallow water of the Strait, the attack

                                bably known at the Strait.

1 September 1944.

        0439 H          Submerged 10 miles north of Batag Island.

        0820 H          Sighted sail boat to southward.

        1840 H          Surfaced 15 miles west by north of Batag Island, manned
                        our automatic weapons and closed the sailboat previously
                        sighted to investigate.

        1853 H          Drew up alongside the small craft to investigate. The
                        boat was manned by eight Filipinos and was carrying a
                        small cargo in rice. The Captain came on board for in-
                        terrogation. They were very glad to see us and had no
                        use for the Japanese. We gave them some food and cigarettes
                        and cleared out to the northward.

        2045 H          Went alongside another sailboat. Information on the
                        Japanese was essentially the same. Since nothing has
                        been sighted in these parts for days will run north of
                        the Polillio Island for a couple of days.

2 September 1944.

                        Submerged northeast of Catanduanes Island.

3 September 1944.

                        Conducting surface patrol northwest of Catanduanes Island.

        0800 H          Submerged on sighting seaplane. (Aircraft contact No. 3)

        0845 H          Surfaced.

4 September 1944.

                        Submerged patrol off eastern entrance to Lagonoy Gulf.

        0735 H          Sighted two planes, probably out of Legaspi heading out
                        to sea. (Aircraft contacts Nos. 4 and 5)

5 September 1944.

                        Submerged patrol southeast of Bingay Point.

approach on it.
0813 H Sighted plane to the northward. (Aircraft contact No. 6)

7 September 1944.

0353 H Sighted small vessel 12 miles south by east of Nagumbuaya
Point, Catanduanes Island. (Ship contact No. 1) Range
6,200 yards. Went to four engines and made an end around
run on it.
0436 H Submerged 12,000 yards ahead of target.
0532 H Fired one torpedo set at zero depth at converted trawler,
range 500 yards, 95° starboard track. Missed. Target did
not know he had been fired at until end of run explosion
11 minutes later at which time he increased speed.
2206 H Set course for Cape Espiritu Santo.

8 September 1944.

Conducted submerged patrol east of Batag Island during day-
light.
1834 H Radar interference from eastward.
1925 H Rendezvoused with U.S.S. WHALE to receive Officer Messenger
Mail.

9-20 September 1944.

Conducted submerged patrol by day off northern entrance to
San Bernardino Straits. At night patroled to eastward re-
versing course to be back at entrance at dawn. This sched-
ule was maintained to cover the Strait in conjunction with
a scheduled operation and not as an area coverage. The
only item of interest occurring during the period was a
downed Japanese medium bomber found 15 miles N.E. by N. of
San Bernardino Light. It did not conform with any type
listed in the recognition manual. It was a twin engine
low wing monoplane with a plexiglass nose and a plexiglass

green house which tapered smoothly into the fuselage. It
had a light machine gun in the nose and one in a turret
aft of the green house. There were no occupants.

21 September 1944.

Being thoroughly disgusted and bored with the area, conduc-
ted surface patrol to the eastward of Catanduanes Island.

0610 H Submerged on sighting an Emily heading our way. (Aircraft
contact No. 7)

0707 H Surfaced.

22 September 1944.

Submerged patrol off northern entrance to San Bernardino
Straits.

23 September 1944.

Conducted surface patrol northeast of Batag Island cover-
ing fleet fueling to the southeast.

After sunset commenced closing Batag Island to bombard.
Information obtained from natives being that the quarters
on the Island was occupied by Japanese. Radar contact on
159 megacycles became louder as we approached the Island,
sweeping at first then holding steady. The radar officer
states that the signal was stronger than any ever heard
in Pearl Harbor. At 4,000 yards the Island blacked out.
The lighthouse keeper quarters at the base of the light
having been well lighted up until this time.

1924 H Commenced firing on the target, expending twenty rounds
common and five rounds high capacity. During the bombard-
ment the radar signals went into convulsions and ceased
emanating. Broke off bombardment because of difficulty
in seeing target and ammunition supply difficulties.

24 September 1944.

The day of scheduled carrier strike from San Bernardino
Strait area. As we have no assigned duties or life guard c
will take station on surface 30 miles northeast of
San Bernardino Light and see what services we can render.
Made trim dive at dawn.

0548 H       Sighted first of many waves of planes coming in from sea-
             ward.

0720 H       Exchanged recognition signals with returning TBF.

1036 H       Submerged for a bogy closing rapidly.

1050 H       Surfaced.

1109 H       Sighted cloud of black smoke rising from over the horizon
             north of Rapu Rapu Island. Assuming it was a downed plane
             set course for it on four engines.

1158 H       Sighted parachute descending in the direction of Catanduanes.
             The chute passed below the horizon on bearing 341° T. which
             was the course we set and went ahead full power, making 20.6
             knots. As the chute dropped over the high periscope hori-
             zon it must have been a long way off. Assistance was re-
             quested from any planes and two fighters were sent out by
             a carrier to help us. We ran all the way to Catanduanes
             Island which was about 18 miles from where we saw the chute
             drop and the fighters searched the Island and the area
             under ideal conditions but nothing could be found.
             From 1400 until 1530 our own planes who seemed to be having
             a holiday after their mornings work gave us many bad moments
             as they cavorted around us. One pair was overheard to say
             between them, "Shall we strafe him or take pictures." We
             talked them out of both using the proper call. One
             bandit, of which we were duly warned by the IFF, flew di-rec-
             tly overhead at 27,000 feet flying out towards our carrier
             group. The performance of the SD and IFF was superb through-
             out the day. With land nearby us and planes everywhere the
             bridge was kept fully informed of any not showing friendly
             recognition. Many times I doubted if our planes were cog-
             nizant of our being in the hole as they would hold their
             attack positions much to long.

1528 H       Our planes started going home and we set course for Freman-
             tle via Batag Island.

1837 H       Commenced bombardment of Batag Island light house keeper
             quarters at range of 4,500 yards. No radar on tonight.
             Many good hits were observed with a fire being started just
             over the ridge. One hit was observed in the house itself
             and the smoke of the light caused smoke to nearly en-
             gulf the light. Many others in the vicinity of the light
             did no apparent damage as seen in the moonlight but it is
             believed that the station was definitely knocked out for

some time. The shooting was far superior to that of last
night. The 40 millimeter ammunition exploding 4,000 yards
would not reach the target. Thirty-three rounds of high
capacity and four rounds common 4 inch ammunition was ex-
pended.

opposite course and was believed to be FLYING FISH of which
we had been warned about. Sent recognition signal by keying
SJ but no reply was received. As it was extremely dark let
her pass with no further attempt to identify.

around to windward and at

2028 H Commenced firing 4 inch and 40 millimeter guns at them. Ex-
pended 14 rounds of 4 inch and 40 rounds of 40 millimeter.

2032 H Ceased firing and went along side each of them in turn to
investigate. Both contained natives. There was no indica-
tion that they were dealing in contraband. Proceeded. The
upper part of the
bow of the one boat had been knocked off
by a 4 inch shell otherwise they appeared undamaged.

28 September 1944.

1005 H Sighted submarine to the eastward, appearance friendly. Set
course to close.

1008 H Submarine submerged. Turned away, fired smoke bomb and
attempted to establish contact by sound.

knots. No screws could be heard. Proceeded being unable
to properly identify it in the darkness existing and con-
sidering it not worth the time to run north to investigate
it in daylight.

30 September 1944.

Enroute Fremantle.

1 October 1944.

0713 H Sighted submarine, 7,000 yards on port bow opposite course,
identified it as British. Exchanged calls with H.M.S.
STURDY.

1520 H Sighted submarine 15,000 yards on starboard bow opposite
course. Characteristics, British. Being unable to see
from the bridge, no calls were exchanged.

(B) NARRATIVE (Continued).

3 October 1944.
    Enroute Fremantle.
2200 H Rendezvoused with H.M.A.S. WARRAMEOR as escort and U.S.S.
    RED.

4 October 1944.
0830 H Made sound tests and ran degaussing range off Fremantle.
0950 H Moored alongside U.S.S. JACK at Fremantle, W. A.

(C) WEATHER.
    In general the weather encountered in the San Bernardino Straits area
was normal and typical of the weather described in the coast pilot during
the Southwest Monsoon season. Local squalls occurred during a few days
and rain squalls were prevalent within radar range nightly.

(D) TIDAL INFORMATION.
    The current north of the one hundred fathom curve off San Bernardino
Light was variable and could not be coordinated with the current tables
for San Bernardino Strait. Submerged station keeping at 2 knots was not
difficult, current velocities being much less than the tabulated veloci-
ties for the Strait.

    Currents encountered off Catanduanes Island and Batag Island agreed
with information obtained from the coast pilot and current chart.

(E) NAVIGATIONAL AIDS.
    All aids to navigation sighted; San Bernardino Light, Ungay Point
Light on Rapu Rapu Island and Batag Island, were unlighted.

(K) MAJOR DEFECTS AND DAMAGE:

The bow planes developed a groan during the last half of the patrol
which is believed to be centered in the tilting ram. The practice of rig-
ging the bow planes in with a 15° down tilt has decreased the diving time
of the ship approximately 10 seconds. However, there is insufficient
hydraulic power to rig them in at this angle except when the external gear
is making very slow speed. The use of a gra-
phite compounded grease help measurably but insufficient grease was on
board to continue its use. It is felt that a more adaptable grease than
the soft mineral variety should be used for this gear.

The need of a Dead Reckoning Tracker and a Low Pressure Blower silen-
cer is keenly felt.

The main engines are incapable of producing rated power without black
smoke. It is believed that there are many broken rings and it is known
that the connecting rod bearings are subject to bearing metal failures.
It is necessary that all pistons be pulled during the coming refit for in-
spection.

The forward and after torpedo rooms receive inadequate ventilation
and are excessively warm in comparison to the remainder of the ship.

[HANDWRITTEN: Lost
Torpedo
9/7/44.(?)] A hot run occurred in number eight torpedo tube which was caused by
improper procedure on the part of the torpedoman while firing an inboard
slug. The torpedo was a total loss.

Two minor torpedo battery explosions occurred in the tubes which re-
sulted in one case of the breaking of two cell jars. The broken jars were
jumped out.

(L) RADIO.

No major defects occurred.

The VHF whip has proved very unstable. The first one carried away
during the training period in Pearl. Another was installed, and our re-
quest for a spare was rejected on the grounds that the new one would never
break. It did, the day after leaving Midway. Since then we have manufac-
tured two more, both of which sheared off after short usuage. The break
in all cases has been at the top of the threaded portion of the whip. The
answer appears to be a whip of greater diameter and higher tensile strength,
the greatest diameter of course being at the threaded section.

There were no transmitter failures, and only one receiver casualty.
On 4 September a ballast tube in the RAL rectifier power unit burned out.

From a communication standpoint, Haiku Fox was eminently successful.

        No serials were missed and, except for the period from 1900 to 2300 Zebra,
daily, reception usually presented no great difficulties.

        A brief of frequency results follows:

        16.68 kc. - Excellent within a 1,500 mile radius of Honolulu.

        4525 kc. - Used occasionally and found quite satisfactory
                   between 1000 and 1600 Zebra.

        6380 kc. - Used occasionally. Satisfactory, but not as de-
                   pendable as 9090 kc.

        9090 kc. - The most satisfactory of the entire group. Used
                   almost exclusively.

        14390 kc. - Very good between 2300 and 0800 Zebra.

        17370 kc. - We had no occasion to rely on this frequency but
                   if necessary could copy it between 2300 and 0600
                   Zebra.

        We transmitted two messages only and had little difficulty clearing them.
on 8470 kc. at 1200 Zebra and on 12705 at 0100 Zebra.

(M) RADAR.

        The SJ-1 radar operated very well throughout the patrol, giving excel-
lent ranges on land. Due to the scarcity of contacts, there was no oppor-
tunity to give it a test in action. The following are normal ranges ob-
tained:
        Land, 2,000-3,000 ft. high             80,000 yards

        Submarine on the surface               11,000 yards

        Large rain squalls                     40,000 yards.

        In glassy sea, trouble was frequently experienced at night with small
pips, apparently of spurious nature, 1,000-4,000 yards in range. Much
speculation was made as to their origin, but since we never could get
these pips under good visibility conditions no definite conclusion was
reached as to their origin.

        The PPI was used almost exclusively in search operation, since it was
usually found that targets could be picked up on the PPI before they could
be seen on the A screen. Considerable use was made of the "steerable

sweep" (precision sweep) feature on the PPI for obtaining accurate ranges
to land. The 25,000 yard position was useful in tracking targets.

Valuable use was made of the key installed on the SJ-1 for communica-
tion purposes. This proved the only means of communication used making ren-
dezvous with the U.S.S. HALE.

The selsyn transmitter working into the TDI system from the radar proved
very valuable to the plotting party.

The following casualties occurred:

14 August C22A in the transmitter unit bias regulator shorted,
burning out R41A, R41B, R41C.

V5 in the transmitter, 6V6G pulse shaper developed an
intermittent short. Replacing these parts cured all
troubles.

29 August One 5V4G tube in regulated rectifier "A" burned out,
causing excessive plate current and low plate voltage.
Replacing 5V4G cured the trouble.

31 August The other 5V4G in rectifier "A" became gaseous, resul-
ting in low regulated voltage, and eventually in symp-
toms identical to 29 August. Again replacing the 5V4G
cured the trouble.

6 September Fuse F9 blew. Found defective 836 rectifier in the
V. power supply and replaced it.

26-27 Sept. On three occasions the PPI sweep disappeared. F2 in
the PPI was blown. The toggle switch for 25,000 yard sweep
was shorting to ground.

The SD-4 was out of commission about eight hours during the patrol.

The following ranges were obtained with the SD-4:

Land, 2,000-3,000 yards high 40 miles
Patrol Bombers 10 miles
F6F Fighter 6-7 miles

No positive indication of enemy D-Fing was noted.

The following casualties occurred:

12 August             Sweep began to jitter in the horizontal and vertical
                      directions. After the base at Midway worked one day
                      and we worked two days, we traced it to arcing at the
                      ground side of the h.v. rectifier tube. The screws and
                      pins on the socket of the h.v. rectifier tube are held at the same r.f. potential
                      by pieces of wire. One screw became loose and arcing
                      occurred. Cleaning the socket and putting it back to-
                      gether correctly restored normal operation.

15 August             Same symptoms of C102. Tightening this connection cleared up the
                      trouble.

The BN and BK operated correctly with no casualties. A sound-powered
microphone plugged into the control unit served as a speaker for indicating
when the BK was being challenged and proved rather useful.

From the time of commissioning until our arrival in Key West we broke
one IFF antenna after the other, each one shearing across the lateral por-
tion close to the vertical dipole. In Key West we had an additional hori-
zontal section welded to an unused IFF dipole. This experimental antenna
is still in operation and holding up very satisfactorily.

The APR-1 and the SPA were manned continuously on the surface. The
following signals were intercepted:

24 August             - r.f. 180 mc., prf 400, 10 microsecond pulses, train-
0800-1100               ing once in 15 sec.

                        off about once a minute. The pulse changed shape
                        as it disappeared, indicating that the transmitter
                        voltage was turned down. The signal operated inter-
                        mittently in this way, training while it was on.

                                                        the signal disappeared. Soon it came back, but with
intermittent operation, and apparently double pulsing.
It finally disappeared, and we did not hear it again.
On the next night when we returned for another bom-
bardment run, the signal did not appear.

        On several occasions, we intercepted and identified friendly airborne
radar in the low frequency and medium frequency bands. The SPA proved
valuable in determining, by watching for lobing, whether the aircraft was
headed for us.

        Strong need is felt for a directional antenna for the APR and for a
remote drive for the dial wheel.

(N) SOUND GEAR AND SOUND CONDITIONS.

        Sound failures consisted wholly of bearing indicator casualties. The
locking pin holding the true bearing repeater cards to the selsyn shafts
on both the JK/QC and the QB equipments sheared. These were replaced and
are operating satisfactorily.

        On 5 September it was found that the bearing indicator of the JK/QC
hoist-train mechanism was nine degrees off the correct setting. This
item will be corrected during refit.

        Sound conditions on the whole, were normal for the area and season.
The paucity of contacts denied us the opportunity of testing the 5 foot
hydrophone which this vessel is provided. Only one unusual noise was de-
tected on the sound gear. Daily, during our operations between San Bernar-
dino Light and Rapu Rapu, an intermittent rapid hammering, not unlike an
underwater machine gun was heard. It was never identified.

(O) DENSITY LAYERS.

        Off San Bernardino Straits an isothermal existed down to 50 to 60 feet.
From 60 feet a gradual negative gradient existed down to 300 feet, the
total gradient being about 10° negative. Ten cards have been forwarded
to the Vice Chief of Naval Operations.

(P) HEALTH, FOOD, AND HABITABILITY.

        The health of the crew was excellent. Two cases of cellulitis re-
sulted in the loss of 6 man days. The Communication Officer fell through
the control room hatch from the conning tower suffering a contusion, abra-
sions and shock. Minor ailments occurring on board were as follows:

The food was ample but not as well prepared as is desirable. The
bread was of poor quality, and the seasoning of food could have been
much improved. The dehydrated foods seemed to be much inferior in
types and in preparation to the dehydrated foods that the Commanding
Officer had experience with a year ago.

The habitability of the ship was excellent with the exception of the
torpedo rooms which were always hot.

(U) REMARKS.

More intelligence information on an area such as San Bernardino Straits
would be of immense advantage upon first going into it. The natives were
very friendly and their information was of considerable benefit after con-
tacting them.

We had gate valves installed in our ten pound blow lines to the fuel
ballast tank while in Pearl Harbor. This simplified the conversion job
immensely. It could be further simplified by a change in the means of
securing the screens around the vents proper.

FIRST ENDORSEMENT to
U.S.S. BARBERO - Report
of First War Patrol.

From: The Commander
To: The Commander in Chief, United States Fleet.
Via: (1) The Commander Submarines, SEVENTH FLEET.
(2) The Commander SEVENTH FLEET.
Subject: U.S.S. BARBERO (SS317) - Report of First War Patrol.

1. The first war patrol of BARBERO, commencing from Pearl
Harbor and terminating at Fremantle, W.A., covered a period of 56 days,
thirty-one of which were spent in the vicinity of San Bernardino Strait.

2. Area coverage was good. One Mark 18-1 torpedo was fired at
a small converted trawler on 7 September. The torpedo missed and no damage
resulted.

3. The bombardment of the suspected radar station on Patag
Island was well conceived, and after the first attempt on 23 September
appeared relatively ineffective, the next night's bombardment produced
the desired hits on the target, apparently knocking out the station at
least temporarily.

4. The shelling of small craft, such as that on 27 September,
should be undertaken only when and after the enemy character of the craft
concerned has been positively established.

5. It is regretted that on this, her first patrol, BARBERO
did not encounter worthwhile enemy targets, but it is felt that the
experience gained will stand the officers and crew of the ship in good
stead, and that when such targets are found the ship will acquit herself
well.

6. With the exception of the bow plane rigging and tilting gear
and the main engines, the BARBERO is in good material condition. The
practice of rigging in the bow planes while at 15 degrees dive has resulted
in placing excessive stresses on the rigging arm and related parts. Grease
lines have been carried away and the motor has been overloaded. It is
considered that the present design will not permit this practice; therefore,
the electrical circuits are being rearranged to conform to the original
plans. Failure to establish a schedule for engine overhauls during suc-
cessive refits caused all engines to be used equally. Thus, a four-engine
overhaul is necessary. The renewal of fifty-four connecting rod bearing
upper halves, together with many parts in the piston assemblies, indicates
the need for more careful engine operations.

Subject: U.S.S. BARBERO (SS317) - Report of First War
Patrol - Comment on.

1. BARBERO's First War Patrol was conducted off
SAN BERNARDINO STRAIT.

2. The area was thoroughly covered, and the patrol
well conducted. The absence of enemy shipping is attributed to
the air strikes being made on the PHILIPPINES by carrier based
planes. The bombardment of the Radar Station on BATAG ISLAND
is approved.

3. The award of the Submarine Combat Insignia is
not authorized for this patrol.

4. The Force Commander welcomes BARBERO's Commanding
Officer, Officers, and Crew to this Force, and congratulates
them on damaging the enemy Radar Station on BATAG ISLAND in a
well conducted gun bombardment.

        Arrived Fremantle, Western Australia, on 4 October 1944. Refit
performed by Submarine Repair Unit. No major alterations were accomplished.
Ship was given routine docking; all main engines were overhauled in as much
as they all had over 1,000 hours of operation and the connecting rod bear-
ings were failing. Refit was completed on 19 October 1944. Two days of
individual ship exercises, one day of practice approaches and one day of
convoy exercises were utilized for training. Readiness for sea date was
advanced from 27 to 26 October 1944.

        The following Officers were detached or reported on board:

        Commander F.A. Greenup - detached - 11 October 1944
        Lieutenant Commander W.L. Fey - reported - 26 October 1944
                (for temporary duty as a P.C.O.)
        Lieutenant J.E. Plummer - reported - 18 October 1944

31 October 1944

2105(H) Sighted and exchanged recognition signals with U.S.S. COBIA by
SJ radar. COBIA warns us of a midget submarine in Lombok Strait.

2110(H) Exchanged recognition signals with U.S.S. DACE. DACE warns us of
small craft ten miles inside of Lombok Strait.

2300(H) Made radar contact on Lombok Island.

1 November 1944

0104(H) Entered Lombok Strait.

0152(H) Sighted low flat boat 3,900 yards on port bow, changed course to
the eastward to clear.

0203(H) Three coast defense guns on western tip of Lombok Island commenced
firing on us. Range was about 14-16,000 yards and all shots
landed from 1,500 to 2,000 yards short, but were on deflection.
Commenced making 20 knots while evading to the northwest.

0230(H) Sighted patrol boat sharp on the starboard bow, range 6,500 yards
and in the middle of the strait. Placed patrol boat on starboard
beam and commenced end around to the westward. Patrol boat open-
ed fire almost immediately, all shots except for one burst of
small stuff fell short. Their heaviest ammunition burst in the
air at a range of about 4,000 yards in a manner similiar to our
40 mm. Never permitted range to decrease to less than 4,500
yards. Enemy speed 12 knots.

0250(H) Having just worked clear of patrol boat, ran into another low
flat picket boat on port bow, range 3,000 yards. Changed course
to the eastward to evade which brought more ineffectual fire from
the patrol boat. Fired five rounds of 40 millimeter at picket
boat but with the extremely poor sights installed on this gun,
we didn't come close.

0255(H) Patrol boat gave up pursuit and went back into Strait.

0415(H) Sighted sail boat to eastward, evaded.

0425(H) Sighted sailboat to westward, evaded. It appears as if the sail-
boats, picket boats, patrol boat and shore batteries are working
as a team. Sent message to the REDFIN warning her of what to
expect.

0522(H) Submerged for trim dive and uninterrupted sleep.

0905(H) Surfaced, proceeding northward to Makassar Strait.

2 November 1944

0626(H) At position Lat. 4° 30' S., Long. 118° 20' E., sighted ship bear-
        ing 050°T, very distant. Submerged and commenced approach.

0740(H) Sighted target through periscope. One escort was patrolling ahead
        and across the target's track. Target appeared to be the Hino
        Maru, page 164, ONI 208-J, and was riding very high out of the
        water, steering a straight course, speed 7.5 knots, course 300°T.
        The ship looked larger than the Hino Maru and the four sets of
        goal post king posts and bridge were similar to the arrangement of
        this ship.

0845(H) With a target range of 1,550 yards, angle on the bow 52° starboard,
        and the escort coming around under the counter of the target and
        heading our way, fired four torpedoes. The torpedoes smoked badly,
        turned away and fired at periscope. Torpedoes
        appeared to be passing astern. About one minute after firing first
        torpedo, fired two more forward with additional lead and
        went deep. One minute and fifty-seven seconds after firing first
        torpedo a low order explosion occurred.

0852(H) Depth charging commenced. First pattern fairly close.

0941(H) Back at periscope depth, target is stopped at the point of attack
        with boats out on both sides. It is still riding high with no
        list or apparent damage. Escort went alongside as we started
        another approach from 4,000 yards.

        Escort got underway and circled target dropping depth charges at
        random. Many men were observed on top of the targets bridge and
        forecastle. Escort also had many men on her, apparently acting
        as lookouts.

1044(H) Escort dropped 6 charges about 2,000 yards on starboard beam of
        BARBERO.

105256(H) With escort making a sweep towards us, fired three torpedoes for-
        ward at target at a range of 1,800 yards. There was one good
        hit in the after well deck which broke the ship in two parts and
        she was settling while the blast was still in the air. The
        other two torpedoes missed ahead. Went deep.

1054(H) Escort dropped two charges, not close.

1058(H) Two charges.

1117(H) Two more charges.

1151(H) One charge, feeble.

                                                                - 3 -

2045(H)    REDFIN reported attack completed, negative results and that convoy
           of two tankers had two escorts, also that she was on port flank.

2105(H)    Made radar contact on one target, range 27,000 yards at Lat. 14°
           01' N., Long. 117° 05' E.

2106(H)    Informed REDFIN that BARBERO was taking starboard flank.

2120(H)    Made radar contact on second target which was about 5,000 yards
           ahead of first. Base course 250°T; zig zagging. Named targets
           "ABLE" and "BAKER" from ahead.

2127(H)    Radar contact on escort, 15° on the starboard bow, range 10,000
           yards and about 10,000 yards from the convoy track. Course 160°T.
           Named him "DUDE".

2133(H)    Made radar contact on second escort to north, range 10,000 yards
           and about 18,000 yards from the convoy. Named him "JOE".

2134(H)    REDFIN attacking. The situation was now as follows: All ships,
           excluding the REDFIN, were on a line of bearing 230° - 050°T in
           following order from southwest: "ABLE", "BAKER", "DUDE", BARBERO,
           and "JOE" at distance of 10,000 yards and
           at distances 5,000 yards and rapidly fading from radar.

2154(H)    Observed successful attack by REDFIN, difficulty was experienced
           in determining which target he had hit.

2205(H)    Determined that REDFIN had hit "ABLE", so went in for attack on
           "BAKER". "DUDE" went to the assistance of "ABLE" and "BAKER"
           reversed course.

2212(H)    At a range of 2,700 yards, with a perfect setup for bow tube
           shots, "BAKER" turned and headed directly for BARBERO. Reversed
           course for a stern tube shot.

2217(H)    Fired four electrics at a maneuvering target. One hit seen
           and felt on the bridge. Two hits heard in conning tower.

2220(H)    Swung right to gain position for a bow tube attack. "JOE" now
           entered the picture and passed close aboard "BAKER" on BARBERO
           side. Signalled by light once in our direction and then signalled
           to "BAKER".

2237(H)    Flying-fish hit Chief Quartermaster, who was manning the
           TBT, directly in the face. He was on his way to meet
           Saint Peter.

8 November 1944 (cont'd)

2238(H) With "JOE" 850 yards on starboard beam opposite course, fired
          five bow tubes at target, range 2,500 yards, 130° port track.
          Upon completion of firing, swung left to put escort astern and
          ordered maneuvering to give her everything. Escort fired one
          shot overhead before turn got started. Cleared lookouts from
          the bridge.

2240(H) Straightened out on course 315°T. Escort 1,350 yards astern
          firing bursts of from 10 - 15 rounds of 20 - 40 millimeter stuff
          at us. BARBERO now making 20 plus knots and no smoke to hide
          behind. Bridge personnel took refuge in front of periscope
          supports and attempted to con ship by watching the tracers
          Escort continued to fire until the range
          had opened to about 2,200 yards. Escort was lit up like a
          christmas tree by the phosphorescent water.

          When range had opened to 4,500 yards, escort became indistinct.
          Sent message to REDFIN that we were being chased, hoping she
          might have an opportunity to attack.

2254(H) Commenced sheering off to right to shake escort, range to target
          not 16,000 yards. Escort continued on northwesterly course.

2315(H) Asked REDFIN if she is in contact with target. She reported
          target bore 093°T, distance 10 miles.

2317(H) With escort now much farther away from target than BARBERO, came
          to an attack course and informed REDFIN that BARBERO was at-
          tacking. Target now bore 155°T, range 12,000 yards; steering
          courses from 150°T to 050°T.

2350(H) Fired remaining two bow tubes at target. Range 2,500 yards, port
          track. One hit sent up a geyser of flame just forward of funnel.
          The conning tower claimed to have heard a second hit. Entire
          after section of the ship became a raging inferno with many
          violent explosions. Bow was elevated out of the water to the
          point where the keel could be seen. Remained about 3,000 yards
          off the target until "JOE" finally came steaming back to remain
          near target. As the wind brought the bow down-wind, the flames
          swept the full length of the deck. Flashing lights appeared on
          the surrounding water which were interpreted to be from life
          saving equipment. Target settled to the point where only fires
          burning at the water's edge were visible.

Enroute Mios Woendi.

1836(H) Sixty miles north of Menado, Celebes Island, contacted several
        planes on SD radar showing friendly recognition. BARBERO in
        joint zone. One plane started on starboard bow, passed all the
        way around the stern and up on port beam at a range of 4 miles
        then headed directly for us so at -

1852(H) Submerged.

1905(H) Surfaced, all clear.

        This plane had radar but the night was very dark. I don't
        see how he could have legitimately attacked any target in the
        joint zone, hence I see no reason for him to make a run on
        us, except to heckle us. That seems entirely unnecessary at
        this stage of the game.

2326(H) SJ contact at 20,000 yards, bearing 250°T.

2328(H) Target group sighted at 18,000 yards in bright moonlight.
        Radar was having difficulties in identifying and staying on
        targets. Engines gave out white smoke as we swung around to
        trail ahead and with the whole set-up being endangered by
        air coverage at -

2335(H) Submerged to radar depth, closing track. Target course 050°T
        speed 10 knots. Group consisting of 8 to 10 ships, including
        escorts.

2351(H) Went to periscope depth. Three escorts are well spaced on
        starboard bow of target group.

29 November 1944

        Conducting approach.

0012(H) With the target group at 4,000 yards, angle on bow 30 star-
        board, target group turned away and one escort began heading
        directly for us.

0014(H) Went deep and received a pattern of 14 depth charges well
        placed as we passed 300 feet. A perfect isothermal existed
        down to 200 feet and I felt sure we were detected by echo
        ranging.

0115(H) At periscope depth, one escort in sight.

0125(H) Surfaced and commenced trailing target group. Sent contact
        report to HADDO and REDFIN. HADDO did not receipt and REDFIN
        was too far to south to get in. (It later developed that
        HADDO was held down practically all night by planes and was
        bombed once.)

0240(H) SD contact 14 miles, target group at 23,000 yards.

0250(H) SD contact had been working between 10 and 14 miles but when
        it came to 8 miles, closing; submerged. There was now but
        two hours remaining before dawn, afterwhich the target group
        would be off the approaches to Manila and not being able to
        raise the HADDO for assistance, called it the end of a bad and
        strenuous day. In retrospect, it doesn't seem logical that
        the convoy would have been routed through our position had
        the planes, which had been heckling us all day made contact.

1722(H)      At Lat. 2° 50' N., Long. 111° 10' E., sighted smoke bearing
             126°T; source not visible in periscope; set course to north
             and east to remain undetected during short period of day-
             light remaining.

2030(H)      Made contact with convoy by SJ and commenced tracking from
             starboard flank. The situation developed as follows:
             The convoy consisted of four ships plus three or more es-
             corts, on base course 325°T, speed 10 knots. One ship was
             smoking badly, otherwise the ships could not be seen. There
             was a quarter moon overhead screened by a light overcast;
             there were many cloud banks around the horizon, particularly
             in the southwest. The moon would set at about 0200 at which
             time the convoy should be out in about 40 fathoms of water;
             depth of water now 17 to 20 fathoms. Planned to track until
             the moon set or a more favorable condition for attack pre-
             sented itself.

2200(H)      A green light was sighted for an instant about five miles
             ahead of convoy.

2210(H)      Lost contact with convoy by radar.

2303(H)      Re-established radar contact. Convoy had reversed course and
             was heading for Cape Sirik. Convoy now appeared very con-
             fused. Speeds of from 0 to 10 knots were obtained on vari-
             ous courses; all around the compass rose.

                     Tracking convoy.

0007(H)      Convoy finally had decided on a base course of 210°T at 10
             knots. Heavy rain and thunderstorm was approaching from
             southwest. Went ahead on four engines to obtain attack
             position.

0015(H)      Storm had developed into a torrential downpour with much
             lightening and thunder. The situation was perfect. Went to
             battle stations. One escort was performing a marvelous
             job for the convoy by staying from 3,200 to 4,000 yards out
             on the beam of the leading pair of ships, another escort
             was out on the beam of the after pair.

NARRATIVE (cont'd)

24 December 1944 (cont'd)

0100(H) Convoy zigged right which pulled the forward escort in. I
turned right and fired four stern tubes at leading pair of
ships, hoping for a torpedo run of not more than 4,500
yards. Actually, the run was about 5,500 yards by the time
we got the torpedoes off and no hits resulted. Firing was
undetected since these were electric torpedoes.

The situation was now much more favorable, however, as the
leading escort had been pulled in to about 1,500 yards and
the after escort was practically alongside the after pair of

013(H) Came in for a bow tube shot on after pair of ships. Fired
6 torpedoes with two degree spread at group, range of 3,700
yards, 80° starboard track, 2,200 yards from escort, who
was nearly dead ahead. Reversed course and easily outdist-
anced escort who came down the torpedo wakes. Just as
course was reversed, leading ship of after group completely
disintegrated in a mass of flame. By the binocular formula,
the flame was 1,400 feet in the air. Target disappeared from
radar screen. Within seconds of the first ship going up,
the second ship of after group was hit and gave off billows
of smoke but no fire.

The two leading ships set off to the eastward at maximum
speed. The second ship hit was dead in the water smoking.

Thirty-seven minutes after the stopped ship had been hit, it
now being at a range of 9,000 yards, a violent explosion
occurred. Following the explosion and continuing for a per-
iod of two or three minutes, flashes at intervals of about
two seconds were observed from target. Target disappeared
from the radar screen.

0207(H) Set course for Great Natoena Island and home.

1704(H) Sighted sailboat ahead.

1840(H) Went alongside native sailboat. Boat was very small and
manned by three natives and had a small cargo of peas and
mill sawed mahogany; proceeded.

2313(H) At a point 33 miles bearing 280°T from Cape Batoe Belat on
Western Borneo, sighted smoke to westward followed immediate-
ly by radar contact at 18,000 yards. Commenced tracking.
Two ships now visible to the eye and on radar.

2337(H) Submerged to radar depth. There were two ships on a line
 of bearing, trailing one smoking very badly as if he is try-
 ing hard to get up on the beam of the leading ship, base
 course 090°T, speed 9 knots, range now 14,000 yards; BARBERO
 dead ahead.

 At 8,000 yards, went to periscope depth. Two escorts deve-
 loped, one on each flank.

25 December 1944 - MERRY X-MAS!!!

0026(H) Commenced firing four torpedoes aft at leading ship, a medium
 or small AK. 90 port track, range 1,100 yards. Trailing
 ship angle on the bow zero, range about 800 yards. Three
 hits, the first of which took off his stern, the second re-
 moved the mainmast section up to the funnel and the third
 was not observed as I was anxious about the second ship.
 Second ship turned away and did not give the first ship and
 angle solver for forward tubes off, having no TDC
 and next due to unrepairable casualty
 and didn't slick quite fast enough
 to get them off. Went deep, 110 feet in 140 feet of water,
 and opened out. No counterattack.

0147(H) Surfaced, area clear. Set course for home.

1100(H) Submerged 60 miles northwest of Karimata Strait for Christmas
 Dinner and await darkness to transit strait.

1805(H) Sighted what appeared to be another submarine about 8 miles
 to south on easterly course.

1902(H) Surfaced 30 miles, bearing 300°T from Seroetae Island.

2020(H) Transited Karimeta Strait.

2140(H) Exchanged recognition signals and calls with U.S.S. RASHER
 who had preceded us through the strait.

2000(H) Patrol craft made off to the northe and nothing more was
         seen or heard of him. (The USS FLASHER was coming down from
         the north being chased by the other patrol craft. Ours left
         and ran the FLASHER down by coming up from the south.)
2230(H) Checked currents at surface and found it to be running north;

C - WEATHER

The weather retained the characteristics of the southwest monsoon
season for this area. The days were usually partially or totally over-
cast but cleared towards evening. Off the northwest coast of Borneo,
con ential rain storms with considerable lightening developed nightly
after midnight. On 8 to 10 December 1944, a gale of medium intensity
was encountered in Dangerous Ground with squally weather continuing for
several days afterwards in the vicinity of Balabac Strait.

D - TIDES INFORMATION

Lombok Strait was transited, northbound shortly after the upper transit
of a full moon. No current was noted. Transiting Lombok Strait submerg-
ed between 0930(H), 27 December and 0240(H), 28 December, certain un-
usual phenomena were encountered; northeast of Bali, three temperature
layers were encountered, each of which had a high relative movement with
regard to the other. While little opportunity was available to observe
the surface current, there was no appreciable current at four hundred
feet. In the central portion of the strait, a preceptable northern set
was encountered at periscope depth four hours before upper transit of
moon but by dropping down in the cold layer again, no current was ex-
perienced. This feature, which probably works in the same manner in
many other straits, could be taken advantage of to make the quickest
possible transits. West of Balabac Strait, the surface current varied
with the direction of the wind.

E - NAVIGATIONAL AIDS

No navigational aids of special interest were encountered.

TORPEDO ATTACK No 1 PATROL NO. 2

TARGET DATA - DAMAGE INFLICTED

DESCRIPTION: Patrolling on course 130°T on possible track of ships
leaving Makassar City, Celebes. 0700(H) Sighted ships bearing 125°T,
distant 20,000 yards and began approach. Target similar
HINO MARU class
Target on steady course 296°T, speed 7.5. Fired 6 torpedoes forward
with one low order explosion heard. Hit stopped target and he lowered
lifeboats. Escort counterattacked and then stood by stopped ship.

SHIPS SUNK: None.

SHIPS DAMAGED or PROBABLY SUNK: One medium AP, similar HINO MARU.
Ship was riding high in the water but apparently had troops aboard.
She was somewhat larger than HINO MARU.

DAMAGE DETERMINED BY: Saw torpedo head for target, heard timed explo-
sion, screws stopped and many cracking noises were heard. The latter may
have been gunfire at position of launching torpedoes.

TARGET DRAFT: 8 feet COURSE: 301 SPEED: 7.5 RANGE: 1550 (at firing)

TYPE ATTACK: Daylight submerged periscope attack. Target on straight
course. Misses due to 2° incorrect gyro angle being generated by TDC.
It is believed that this error was due to high speed rollers in fwd.
sinc follow up head either having been set inaccurately or slipped out
of adjustment on the shaft. Excessive back lash found in follow-up
head which could also account for generation of incorrect solution.

After firing first four torpedoes and observing them run, it appeared ob-
vious that they were going to pass astern. The two remaining torpedoes
were then fired forward with additional lead. Due to proximity of escort
it was impossible to observe run of last two fired, but one hit, a defin-
ite low order explosion, at correct running time was heard. The explosion
was of about one quarter of the intensity of a normal explosion and was in
two parts separated by about one second. Had the target not been observed
later stopped with boats over the side, there would have been some doubt as
to whether a hit occurred. The target did not take a list or appear to
settle any as a result of the hit.

DESCRIPTION: At 1600(H), began closing two tankers, two escorts report-
ed by REDFIN. Picked up radar contact at 2105 and began tracking.
Found tankers in column with escorts astern. REDFIN reported one attack,
no results. Assigned REDFIN to targets port flank and began crossing
astern to starboard flank. Passed between escorts astern and got on tar-
gets starboard quarter. Saw flash on target ahead. Second tanker reversed
course. Came to 100 port track on second tanker. Each escort began clos-
ing one tanker. Target changed course towards. Came to course 287o and
fired stern tubes. One hit observed, another heard in conning tower.
Target swung right. Came hard right to bring bow tubes to bear for attack
number 4.

SHIPS SUNK: None.

SHIPS DAMAGED or PROBABLY SUNK: One "Able Oboe" (AO), 10,000 tons, class
unknown, 600 feet by binocular formula.

DAMAGE DETERMINED BY: Saw flash as one torpedo hit in proper time
interval. Another explosion was heard but not seen.

TARGET DATA - DAMAGE INFLICTED

DESCRIPTION: After attack #4, ran from escort until lost sight of him;
radar plot showed him still chasing. Came right and closed target leav-
ing escort to chase our shadow. At 2,500 yards, fired two tubes for-
ward at target. He burst into flames, exploded, and began sinking. Es-
cort, meanwhile, had given up chase and was slowly closing target. After
target began sinking, he closed and stayed near-by. We circled, watching

DESCRIPTION: At 2313(H), 24 December 1944, saw smoke on horizon and at
same time had radar contact. Began tracking. Target appeared to be two
ships on line of bearing with an escort on each flank. Tracked target on
course 090° at 10 knots. Speed was solved perfectly so dove to radar
depth on targets track to avoid detection in moonlight. At 5,000 yards,
went to periscope depth and tracked by bearings only. Trailing target
appeared to be small oiler or engine aft freighter. Leading target a
medium freighter. Obtained firing position 1,100 yards on port beam of
leading target and directly ahead of trailing target. Fired four tor-
pedoes aft at leading target. Three hits. Other target turned radically
away, ruining a hoped-for shot at him. Went to 100 feet, evaded escorts,
no counter attack.

SHIPS SUNK: One medium AK or combination AK-AP, about 3-5,000 tons.

SHIPS DAMAGED or PROBABLY SUNK: None.

DAMAGE DETERMINED BY: Heard three timed hits. Saw target after each
of first two hits, first one took off his stern, second one after section
up to his funnel, effects of third not observed as the second target was
under close scrutiny.

| REMARKS | | | | |

Had the TDC angle solver for forward tubes been operative, torpedoes could
probably have been launched at second target. Attack was conducted in 140
feet of water.

Target was not identified but was a mast-funnel-mast, plumb bow, counter
stern, possibly split superstructure, high thin funnel ship. It appeared
to have a high deck cargo. Target was visible at 16,000 yards in hazy
moonlight.

I - MINES

No mining activity was observed. One drifting mine was encountered
at Latitude 13° 08' N., Long. 117° 30' E. It was of the spherical horned
type and appeared to have been in the water for a long time.

J - ANTI-SUBMARINE MEASURES

In all encounters with anti-submarine vessels accompanying convoys,
it appears that they are standardized on one patrol craft for each ship
in the convoy. Whether their primary purpose is to protect or pick up survivors
is open to question. Of three submerged approaches, only in one case
were they using echo ranging, but in that case, with conditions extremely
favorable, they were successful in picking us up. No anti-submarine ves-
sels encountered had a speed in excess of fifteen knots, and they were
easily out run on the surface. The small escort vessel encountered west
of Makassar City dropped thirty-eight depth charges in a relatively short
period. During that period, it was observed to go alongside the damaged
ship and it is believed he picked up a reload as he was probably incapable
of carrying that many. He dropped charges at random around the damaged
ship which was of great assistance in making the second approach as he
kept us continually informed between periscope observations of his range
and that he had no idea where we were. That practice also enabled us to
come back to periscope depth much sooner after the initial counterattack.

The escorts encountered on the night of 23 December must have either
detected one of our radars or become suspicious and turned back for some
reason not connected with our presence. A green light sighted just prior
to their reversal of course and about 8,000 yards ahead of the convoy is
unexplained.

J - ANTI-SUBMARINE MEASURES (cont'd)

Many aircraft were encountered off the western approaches to Manila.
Air-borne radar equipped planes were used at night and were most effective
in handicapping our movements. There was no evidence of homing on either
the SD or SJ radars, both of which were keyed at night.

Patrol craft, coast artillery, picket boats and aircraft are used at
Lombok Strait but on such a limited scale as to only make it dangerous to
transit. They have certainly made no concentrated effort to block its use.

E - MAJOR DEFECTS AND DAMAGES

          The port reduction gear was damaged by an aerial depth bomb while
passing through Lombok Strait. While operating at 80 rpm submerged, a
loud knock developed. When backing on the port shaft, a grinding sound
was heard in addition to the knock. The trouble may possibly have been
in the thrust bearing. No definite cause for the noise has been determined
by ships force.

          The SD radar should be replaced with a unit capable of more re-
liable and uniform output.

          The periscope is urgently needed.

          The mark 3 TDC should be replaced with a more flexible unit
capable of tracking at greater ranges, incorporating solutions for
longer torpedo runs and a semi-automatic spread setter.

          A dead reckoning tracer is a must on the alteration and im-
provement program.

          The following TDC casualties occurred:

          (a) Casualty #1 - Forward angle solver generated two degrees
              left gyro angle error. This error was caused by the
              forward sine follow-up head being off its zero position.
              Sine head was reset by ship's firecontrolman on its
              the high speed rollays adjusted to
              split the error equally right and left.

          (b) Casualty #2 - Forward angle solver generated an in-
              creasing error on all gyro angles of over 30°, maximum
              error 2 1/2° on a 90° gyro angle. This error was
              caused by forward cosine follow-up head being off its
              zero position. Cosine head reset by Subron 16 relief
              crew at Mios Woendi.

          (c) Casualty #3 - Forward angle solver generated error of
              from 1 1/2° for a 0° gyro angle to 7 1/4° for a 90°
              gyro angle. This error was caused by failure of radius
              of turn (Z) cam unit being in forward angle solver cam unit being
              rotated by input (G) gyro angle. This error was caused
              by the following: The four mechanical pin stops, which
              limit the lower setting of input "Z" cam had sheared off
              and became wedged between the "Z" cam and its housing,
              preventing rotary motion of the cam. As a result, the
              slip gear located on the gyro angle input shafting to
              the base line resolver had lost most of its set pressure
              and was unable to overcome the counter torque required
              to rotate the base line resolver and the radius of turn
              cam, hence, there was no "Z" output to gyro angle order
              transmitter, producing erroneous gyro angles.

U.S.S. BARBERO (SS-317)

K. MAJOR DEFECTS AND DAMAGES (cont'd)

The air conditioning plant still does not put out its full capa-
city. The present expansion valves, although wide open, permit gas
with too much superheat to return to the plant. At present, the hand
expansion, or by-pass valves are partially open to supplement the ex-
pansion valves. The air distribution to the forward and after torpedo
rooms is still insufficient. The need for a booster of some kind in the
system is keenly felt by personnel berthed in those compartments.

The forward bearing on No. 4 main engine was found to have too
little clearance which caused this bearing to run hot (173°F at stand-
ard speed on four engines). The bearing was replaced by a spare with
proper clearances and the running temperature was reduced to about 145°F.

The hydraulic plane caused much concern during the entire patrol.
Upon departure, Fremantle, the paint was noisy. This was found to be
due to improper functioning of the pilot valve linkage installed during
refit. This linkage is a fine thing in theory, but is unreliable in
practice due to the lack of proper machining. It was found to jam with-
in its own mechanism. By liberal application of oil and use of washers
to increase clearances of operating arm, the operation was materially
improved. Inspection of the system by the hydraulic crew from the USS
ORION showed that the pilot valve and both by-pass valves were badly
scored. They recommended renewal of those valves and the re-packing
in the accumulator. It is felt that the the condition of the pilot valve
and by-pass valves is due to dirt in the system. It is requested that
the entire system be flushed out during the next refit and that the
Bureau alteration requiring filters in the system be accomplished.

Number three main engine and auxiliary engine outboard valve
jammed open on the surface and was finally forced shut by hand. In
spection topside showed that the bracket holding the pin at the ujunc-
tion of the operating linkage and the valve flapper was cast loose on
the forward side. Both holding bolts had vibrated loose and fallen
out. Keepers for those bolts are unsatisfactory. Inspection of the
other valves showed that in every case the keepers had corroded by
repair and were useless as keepers. It is requested that during the
next refit these bolts be drilled and wired with non-corrosive wire.

The detached circulating water system installed during the
first refit developed several defects. The fresh water pumps are too
low in the engine room bilges and frequently are drowned by salt water.
Especially when the water sloshed forward due to the angle of dive.
The capacity of the system is insufficient to produce any rapid cooling
down of the engines. It is desirable that the system as designed
for this class be installed at the earliest possible time and as a
stop-gap, the present pump be raised out of the bilges and placed on the
bulkhead.

At the outset of the patrol, the main induction leaked badly
around the valve seat and as the depth increases on a dive the leak
became larger. The repair crew on the U.S.S. ORION found in testing
that the valve linkage was out of adjustment. The defect was remedied
and no trouble has been experienced since.

There were no major defects.

Reports from stations receiving our early messages indicated a
faulty transmitter, even though it appeared we were putting out a good
signal.

A thorough check of the transmitter was made. The keying relay
was cleaned and adjusted for best results as well as we could do it
without the proper equipment. The transmitter was meticulously cleaned
out and all relay contacts cleaned off. All tubes were replaced. The
calibration of the TBL-12 was done properly. It is believed the
trouble was partially due to a faulty HF Asc. tube and partially to
an improperly operating keying relay.

The HF antenna current meter shorted out, resulting in high power
amplifier plate current. Since no spare was available, the meter was
by-passed until it can be repaired or replaced.

It was found we could not communicate with the base on the IF
section of the transmitter. The resonant point of all stages did not
coincide with those listed on the tuning charts. Changing the posi-
tion of the IFF-MO range switch did not affect the tuning. Inspection
showed the extension rod connecting the range switch to the capacitor
back was loose. Operation was normal when the locking nuts were
tightened.

There were no receiver failures.

Wolf pack communication with the REDFIN was excellent. That
with the HADDO only fair. Confusion seems to arise from the similarity
of call signs used by packs from CTF 71 and CTF 17. It is suggested
this condition could be alleviated by the usage of 3 character calls
by one of the task forces in question.

VHF communication was, on the whole, quite satisfactory at short
range. The HADDO had only one channel available. The REDFIN reported
she could not hear us on channel 2, so communication with her was car-
ried out on channel 4. Since no instruction books were issued us on
this equipment (other than operating instructions) a thorough check-up
on the VHF could not be performed.

No jamming which could be positively identified as such was
noted. Using the same wolf pack calls day after day brought up the
question of whether or not the Japanese could receipt for traffic us-
ing proper authentication, since authenticators change only on an
hourly basis. It is believed this possibility could be obviated by
using the authentication system supplied by the current edition of
CSP 1270.

Reception of VIXØ "Bakers" was universally good. Only three
serials were missed (as a result of being held down over long periods
of time by air patrols.) Subsequent messages indicated the serials

did not concern us, so no request was made for their repetition.
A resume of "Baker" reception results follow:

Freq.                 Remarks
4370 kcs.             Used at times between 1800-2300 GCT. When
                      reception on 9250 was poor.
9250 kcs.             Excellent between 0900-2200 GCT. Infrequent-
                      ly found it impossible to copy between
                      1800-2200.
12630 kcs.            Used only as standby for 9250. Good from
                      0800-1600 GCT.
16150 kcs.            Good from 2300-0900 GCT. Signal strength
                      S3 - S5 with no interference.
General               9250 kcs. and 16150 kcs. were found to
reception             be the best frequencies and were universal-
                      ly employed. 4370 kcs and 12630 kcs were
                      used standby frequencies when reception on
                      9250 kcs and 16150 kcs was poor.

Five messages were sent to VIXØ while this vessel was on station.
Of these, two were cleared to VHM, two to VHA1 and one to VHJ. All
were transmitted on 8470 kcs. All at about 1300 GCT. At no time
was VIXØ heard to answer our call-up, although once that station is
believed to have given us the go ahead signal just as we started trans-
mitting to another station. No trouble, excepting that previously men-
tioned in regard to our faulty transmitter, was experienced in the
transmission of these messages.

Two days prior to the departure of this vessel on patrol, it
was discovered that the DQ loop was grounded out due to the fracture
of the porcelain insulators thereon.

As no spare insulators were available at the base, the loop
was removed and the flange blanked off.

V. RADAR

SJ-1 RADAR - The SJ-1 performed very well and very consistently through-
out the patrol, with very light casualties and very little time out of
commission. Its reliability in two surface attacks was outstanding.
The "precision sweep" feature on the PPI was again proved useful in obtain-
ing accurate ranges to distant land peaks. The following ranges were
obtained as the maximum:

Submarine 14,000 yds
Loaded tanker 20,000 yds
Empty tanker 27,000 yds
Serutu Island, 1600 ft. elevation 29 miles
Mt. Kina Balu, 13000 ft. elevation 93 miles

The last range was a second sweep echo determined approximately by
measuring pulse rate on the APR-1/SPA combination.

The following casualties were experienced:

(a) C22-B in the transmitter shorted, causing bias to be
lost on the 5D21, and resulting in high plate current.
This casualty has been experienced twice before, and it
is strongly recommended that these condensers be re-
placed with units of higher voltage ratings as a field
change. We have installed a 0.5 microfarad condenser
in series, which should increase the voltage rating of
the combination with a slight reduction in capacity.

(b) One of the wipers on the feeder unit became worn, caus-
ing jumpy "A" sweep and erratic lobing. We replaced
the wiper.

(c) I.F. gain went dead due to parting of coaxial cable P2
in the transmitter-receiver unit. We replaced the cable.

(d) Lobing contacts in antenna assembly became dirty so
that the lobing motor failed to operate.

(e) M1, the Regulated Rectifier voltmeter in the control
unit, burned out, and was replaced by the spare, which
operates in a sluggish manner.

(f) The range step became displaced to the right and lost
its shape. This was traced to failure of L1 in the in-
dicator unit (delay multivibrator) for which there are
no ships spares. This was replaced by a spare L1 out
of the transmitter which, though of twice the inductance
served the purpose.

In addition, two 5V4G's and several 6AC-7's out of the IF stages went
bad and required replacement.

C-O-N-F-I-D-E-N-T-I-A-L
M - RADAR (cont'd)

The SJ-1 also served a valuable recognition and communication
function. It was used in communication with a great number of submar-
ines, and only on one occasion did we fail to establish communication
with a U.S. submarine.

SD-4 - The SD-4 radar operated in its usual undependable manner, some-
times detecting aircraft at ranges of 14 miles or better, and at other
times letting them go until they closed to 4 miles. The preamplifier
gave considerable trouble; at the beginning of the patrol we suspected
that it was not giving us gain. Inspection revealed a variable cond-
enser to be shorted. On two other occasions, the mica insulation at
the plate terminal of a tube shorted to ground, causing two resistors
in the plate and power supply circuits to burn up. Once this caused
the power transformer to smoke, filling the control room with smoke.
The preamplifier should be fused to prevent such damage.

IFF - The BK gave no visible trouble. It was operated in accordance
with the current recommendations, and on several occasions we believe
that it was successfully challenged by aircraft, either by 175 mc air-
borne radar or airborne interrogators.

The BN operated satisfactorily during the main part of the pat-
rol, being kept warmed up at all times on the surface. During the lat-
ter part of the patrol, it developed a habit of being triggered with
the SD-4 on even when the "IFF" switch was off. Efforts to correct
this have not met with very much success and we are not well convinced
that it is in normal operation.

N - SOUND GEAR AND SOUND CONDITIONS

Sound gear operation, on the whole, was satisfactory. There
were no major defects.

JP-1 operation was excellent. Ranges were greater and bearing
accuracy more sharply defined on this equipment than on the WCA-2 gear.
Sound conditions were good throughout the patrol, an isothermal layer
existing, in most instances, between 200-300 feet.

Three casualties occurred on the WCA-2 equipment. The QB sound
head was trained beyond its limits, tearing out the lead-in cables and
jamming the mechanical stop. The small bevel gear on the hand train-
ing shaft was stripped and the shaft upon which the mechanical stop
rides was bent.

N. SOUND GEAR AND SOUND CONDITIONS (cont'd)

The casualty occurred because the electrical limit switch fail-
ed to operate, allowing the training mechanism to rotate until the mech-
anical stop was reached. Since there is considerable power on the gears,
a dowel pin was wrenched loose and the hand training shaft, now being
misaligned, was bent and its bevel gear stripped.

The equipment was placed back in commission without a mechanical
stop and without the hand training feature. The limits of rotation
now depend entirely upon the electrical limit switch. This switch was
carefully inspected and tested, and no cause for its failure could be
determined.

It is extremely possible that this failure of the electrical
limit switch will reoccur. If so, the same casualties will result. It
is therefore recommended that a more positive switch be designed and
that additional means of protection be incorporated in the equipment.
It is suggested that the utilization of a shear pin in the large bevel
gear would protect all gears and shafts from damage, while still permit-
ting rotation of the sound head. In this event, only the input leads
would be pulled loose.

An alternate means of protection could be provided by the incorp-
oration of a visual indicator on the conning tower sound stock to show
when the sound head has been trained beyond the electrical limit switch.
This feature could be accomplished by the installation of a switch at
each end of the worm gear on the hand training shaft, the switches be-
ing operated by a dog riding up and down on the worm gear. These
switches, upon contact being made, would energize the light in the con-
ning tower.

The visual and visual-audible operation of the fathometer failed
entirely, while the audible operation was only fair. The sensitivity
control was ineffective and the volume of the speaker was not great
enough. It was found by inspection that the leads on the sensitivity
control and one side of the speaker were grounded from wearing against
the chassis when opening and closing the panel door. One 6D6(V701)
burned out as a result of this ground.

A 41 (V708) was found to be gassy. Replacing these tubes and re-
pairing the insulation on the two leads resulted in normal operation
of the equipment.

The ranging indicator of the WCA-2 equipment would not key on
either the QB or JK/QC systems, but would key on manual. It was found
that one of the keying contacts on the motor in this unit was not
making contact. The contact was readjusted and operation was normal.

O - DENSITY LAYERS

     In general, no appreciable gradients could be found at depths
less than 200 feet. Between 200 and 300 feet, pronounced gradients
were found in almost all cases, excellent for balancing though probably
too deep to block enemy echo ranging.

     Gradients of as much as 10° in 20 to 40 feet were found in
Lombok Strait. The sharpness of these gradients seems to indicate
shallow and deep currents which flow in
that they coincide with the
the strait. The line of demarcation between these currents varied in depth
from 200 to 350 feet at different times of the day, depending upon the
contour of beaches, the depth of the channel and the period of the tide.
There was no marked changes in trim necessary to pass from layer to
layer and it was found that practically no tidal current existed below
350 feet.

P - HEALTH, FOOD AND HABITABILITY

     The health of the crew was very good. In fact, there were no
cases of sickness which could be traced directly to war patrol conditions.

     The following cases required treatment by the Pharmacists Mate:

          Lymphangitis, left leg                     sick days - 8
          D.U.(appendicitis, chronic)                sick days - 2(BL)
          D.U.(fracture, left great toe)             sick days - 3
          Shock; contusions, left chest and
          scapula region                           sick days - 3
          Cellulitis, left foot                      sick days - 0
          Boil, left forearm                         sick days - 2(BL)
          Conjunctivites, purulent, left eye         sick days - 6

     The food was ample and very well prepared. A baker was obtained
prior to commencement of patrol and leading cooks were swapped while
alongside the USS ORION which resulted in a great improvement in food
preparation.

     A shortage of meat, sugar and flour developed for the following
reasons:

          Meat: Surveyed 1,275 pounds. When the meat was taken from
                the icebox and thawed, it smelled bad and evidence of
                mold was present. It appeared that the meat had been
                thawed out and refrozen some place before coming on
                board. The Australian frankfurters tasted like they
                were half saw dust.

          Sugar: Much more sugar was used in baking.

          Flour: Surveyed 400 pounds of tinned flour. This flour
                had been brought from the states and when opened it
                was caked hard and mildewed. Some of it was salvaged
                by crushing but that which was salvaged would kill the
                yeast in bread making.

F - HEALTH, FOOD AND HABITABILITY (cont'd)

        The habitability of the ship was much improved over the last
patrol. Primarily this was due to the fact that it was almost entirely
conducted on the surface. The sound equipment has a tendency to heat
the forward torpedo room up considerable when submerged.

Q - PERSONNEL

        The performance of the personnel was excellent. No temper-
mental problem cases developed, they were all steady and cool in
combat and in no case were there any personnel failures which could
have in any way endangered the ship. The new members of the crew
obtained in Fremantle, were outstandingly good material.

        Statistics on enlisted personnel:

        (a) Number on board during patrol                                71
        (b) Number of men qualified at start of patrol                  54

T - FACTORS OF ENDURANCE REMAINING (cont'd)

The above information doesn't mean very much as the conditions of
operation involved is such a factor. The last twenty-four days on station
were very exhausting from sheer boredom. The lack of sufficient magazines
books and playing cards was keenly felt. The nerves of all hands were
beginning to get on edge and speaking for the Commanding Officer, I found
it almost impossible to sleep and suffered as a consequence in efficiency.
As soon as the trip home was started and targets became available, the
personnel endurance went away up.

U - RADIO AND RADAR COUNTERMEASURES

No enemy use of radio countermeasures were observed.

The AN/APR-1 radar intercept receiver was manned continuously
on the surface, in conjunction with the AN/SPA pulse analyzer. The
following contacts were made, which are believed to be enemy:

(a) 4 November 1944, 149 mc, 450 pps, 11 microsecond pulses,
sweeping every two minutes, with minor lobes in evidence.
This was believed to be situated in vicinity of Sibutu
Passage and to be Mk I Mod 3 air search equipment.

(b) 5 November, 198 mc, 1200 pps, 6 microsecond pulses.
This also trained slowly, appeared to be ship borne air
search, Mk II Mod 1, but our proximity to Cagayan Island
pointed to the possibility of its being land based.

(c) 27-28 November, 147 mc, 1000 pps, 8 us pluses would
periodically steady on us and grow larger in intensity.
We believe this was airborne Mark VI Mod 4. Our position
was off Mindoro Strait and these planes seriously inter-
fered with our approach on a convoy as mentioned elsewhere
in this report.

(d) 18 December, 75 mc, 500 prf very weak. Appeared to be
air search on the northern tip of Borneo, near Balabac
Strait.

In addition, several contacts were made that were identified as
friendly aircraft, although we were forced down by them because they
come straight in on us.

Several deficiencies are felt in the APR receiver. The dials
should be motor driven, for it is tiresome to turn the knob continuously.
A switching arrangement for changing tuners would be very useful, because
it would make possible more thorough coverage of the low and high frequ-
encies.

U - RADIO AND RADAR COUNTERMEASURES

Possible noise modulated jamming was encountered on 3 November off
the west coast of Celebes. It covered the JN-2 unit of the APR and the
screen of the SD. It was decided that this jamming was not very effective
and that we could have seen an SD contact through it.

We attempted no jamming or deception.

V - REMARKS

The passage of Lombok Strait is definitely hazardous during periods
of full moon. Some type of neutralizing work by surface or air forces in
this area would be greatly appreciated. In as much as only float type
planes were observed in the area, it doesn't appear as if there is an
airforce worthy of the name in the vicinity.

The spending of 23 days in an area without a ship contact is the
most tiring part of a patrol.

The performance of duty by all officers and men were in accordance
with the highest traditions of the Naval Service and for their alertness
and proficiency in the performance of their duties they are commended.

Subject: U.S.S. BARBERO (SS317) - Report of Second War
Patrol - Comment on.

1. The Second War Patrol of the BARBERO consisted of
two phases, separated by three days spent in MIOS WOENDI for torpedo
replenishment. The first phase, lasting from 26 October until 16
November, was conducted in MAKASSAR STRAITS and in the area west of
MINDORO. The second phase lasted from 18 November until 12 January
1945 and was conducted in the SOUTH CHINA SEA northwest of BORNEO.
During both phases BARBERO was a member of a coordinated search and
attack group consisting of BARBERO (OTC), REDFIN and HADDO.

2. The first attack, on 2 November, resulted in one hit
on a small AP, and the Commanding Officer is of the opinion that
this hit, which stopped the target, resulted in a low order
explosion. The second attack produced a normal explosion which
broke the target in two, and sank it. During the evening of 8
November, BARBERO joined REDFIN to execute a series of coordinated
night radar attacks on a convoy of two tankers and two escorts.
BARBERO made three attacks, fired eleven torpedoes, made three hits
and observed the target to sink. Following the reload at MIOS
WOENDI, the next two attacks were made on 24 December, when a convoy
of four ships was attacked twice, and ten torpedoes were fired,
sinking a gasoline loaded tanker with one hit, and damaging another
unidentified ship with one hit. The final attack was expertly
conducted in shallow water on a two ship convoy with two escorts.
Three hits out of four torpedoes fired blew the target to pieces.

3. The Commanding Officer's remarks recommending the
neutralizing of LOMBOK STRAIT are noted, and it is gratifying to
report at this time that our air forces have launched several very
effective attacks in this area recently, and have doubtlessly
succeeded in neutralizing much of the opposition in question.

4. The award of the Submarine Combat Insignia is
authorized for this patrol. [HANDWRITTEN: ✓]

CO-ORDINATED ATTACK GROUP

A - PROLOGUE

On or about 17 October 1944, notice was received that the
BARBERO (Commanding Officer, OTC), REDFIN and HADDO would probably
operate as a co-ordinated attack group. The above three ships operated
at sea as a group on 24 October in a convoy exercise. The BARBERO and
REDFIN departed Fremantle, W.A., in company on 26 October 1944. The
HADDO was still at sea, hence, there was no opportunity to discuss tactics
with the Commanding Officer of the HADDO. The HADDO departed Fremantle
on 28 October 1944.

CO-ORDINATED ATTACK GROUP

D - REMARKS (cont'd)

          set up, attacks on ships leaving port could be delayed long
          enough to get enough boats in position and the ships far
          enough out at sea to insure destruction of all ships.

CONFIDENTIAL

FIRST ENDORSEMENT To
CO USS BARBERO Conf. Ltr.
SS317/A16-3 serial 024
dated 2 January 1945.

From : Commander Submarine Squadron TWENTY SIX.
To : Commander-in-Chief, UNITED STATES FLEET.
Via : (1) Commander Submarines, SEVENTH FLEET.
(2) Commander SEVENTH FLEET.

Subject: Co-ordinated attack Group - USS BARBERO (SS317),
USS REDFIN (SS272) and USS HADDO (SS255) - Report
of War Patrol.

1. The Co-ordinated attack Group consisting of BARBERO, REDFIN
and HADDO, with Commander I. S. Hartman, USN, Commanding Officer, BARBERO, as
Group Commander, succeeded in effecting good area coverage during the period
covered by the group.

2. Only one co-ordinated attack was made and that involved only
BARBERO and REDFIN, as HADDO had not yet joined the group, and was too distant
to join in the attack. The interchange of information between the two ships
participating was very satisfactory and a great amount of damage was inflicted
by multiple attacks by the two submarines. All three of the submarines separately
inflicted other additional damage to the Japs, but these attacks were all indepe-
ndent of any co-ordinated group action.

3. The group was well directed by the Group Commander, area coverage
was well planned, and the one co-ordinated attack well and successfully executed.
This convoy suffered far more damage than would have been inflicted had both
submarines concerned been operating independently.

4. The Commanding Officer, BARBERO, is congratulated on the conduct
of the group under his direction and on the considerable damage inflicted on the
enemy, as well as the valuable experience gained by all commanding officers of
the group.
