HISTORY OF USS PICUDA (SS 382)

The PICUDA was built at the U.S. Navy Yard, Portsmouth, New Hamp-
shire, keel laid 15 March 1943, launched 12 July (sponsored by Mrs.
R.H. English) and commissioned 16 October. During the construction
period the officers and crew were assembled at Portsmouth and given
all schooling and training offered from the various sources at that
time. The Ship was accepted on 18 November and commenced her underway
trials under the command of Lieutenant Commander Albert Raborn, USN.

(A) Prologue.

          The U.S.S. PICUDA was built at U.S. Navy Yard, Portsmouth, N.H., keel
laid 15 March, 1943, launched 12 July and commissioned 16 October. During
the construction period the officers and crew were assembled at Portsmouth
and given all schooling and training offered from the various sources at
that time. The shore based training and schooling offered by Portsmouth
Navy Yard were taken with enthusiasm, much was learned and time saved in
organizing and in giving basic training. The set up at Portsmouth for this
purpose was excellent. The following officers commissioned and fitted out
the PICUDA and are now attached to this ship, Lieutenant Commander Albert
Raborn, U.S. Navy, Commanding; Lieutenant John A. Bogley, U.S. Navy, Execu-
tive and Navigator; Lieutenant Andrew M. Wales, U.S.N.R., Engineer; Lieut-
enant Henry J. Kuehn, U.S.N.R., Gunnery and Torpedo; Lieutenant Henry B.
Sweitzer, U.S. Navy, Communications; Ensign John A. Heagy, U.S.N.R., Commis-
sary, Stores; and Ensign (T) Homer W. Chellew, U.S. Navy, First Lieutenant.
The ship as accepted 18 November and commenced her underway trials, train-
ing and shakedown in Portsmouth area. Torpedo test firing and tube trials
were held 14, 15 and 16 December at Newport, R.I., test firing thirty Mark
XXIII and five Mark XVIII-1 torpedoes. In New London, Connecticut area 17
to 31 December all uncompleted trials were held. During this period four
Mark XIV-3A excercise torpedoes were fired on practice approaches and six-
teen Mark X drill mines were laid. The ship was depermed at Submarine Base,
New London. A sound test was conducted in this area. 1 January, 1944 the
PICUDA departed New London area to join U.S. Pacific Fleet via Balboa, Can-
al Zone. On 13 January, 1944 at Balboa, C.Z. the PICUDA reported to CinC
Pacific Fleet for duty and joined the Submarine Force Pacific Fleet, Sub-
marine Squadron 20, Submarine Division 201. Upon arrival Pearl Harbor, T.H.
27 January, 1944 the ship having completed her initial training and shake-
down, was assigned to Subron Four for upkeep and voyage repairs. 31 Janu-
ary the final training commenced under the Submarine Training Command, U.S.
Pacific Fleet and Commander Submarine Division 201. The period 31 January
to 15 February underway training was conducted in periscope approaches,
radar approaches, night surface radar approaches and battle surface. Two
depth charges were dropped close aboard for indoctrination. Six Mark XIV-
3A and four Mark XVIII exercise torpedoes were fired on practice approaches.
Thirty rounds of 4" and six pans of 20 mm ammunition were fired at target
streamed by U.S.S. FLORIKAN on battle surface practices. On 6 and 7 Febru-
ary the PICUDA participated in a convoy exercise with the U.S.S. LAPON on an
outgoing screened convoy. Much was gained on this exercise and it is con-
sidered invaluable in the training of this ship. Two night approaches were
made on this convoy. On 9 and 10 February the PICUDA joined the U.S.S.
SILVERSIDES and U.S.S. LAPON in a camouflage test and exercise off Kona
coast, Hawaii, T.H. A report of this test has been made by other sources.
The PICUDA has the dark camouflage. During the training at Pearl Harbor
two additional officers were assigned to the PICUDA, Ensign Robert C.
Meacham, U.S.N.R., Radar officer and Ensign Joseph R. Fernald, U.S. Navy.
On 14 February the ship was sound tested in West Lock. Too much cannot be
said for the training received at Pearl, it is believed that the only train-
ing left that can benefit a ship is the actual experience of war patrols.
The PICUDA loaded 15 and 16 February and departed on her first war patrol
17 February, 1944.

(B) Narrative.

17 February 1944.
1300 (V-W) Departed Pearl Harbor, T.H. for Midway, T.H. with PC 603 as escort.
            Commenced operations in accordance with Comtaskfor 17 Secret Opera-
            tion Order No. 57-44 of 16 February 1944 as task unit 17.2.6.
1915 (V-W) Released escort. Set course 320°T. speed standard about 13 knots.
            Surface cruising.

18 February.
0718 (V-W) Made quick dive to 100 feet. Surfaced at 0800 (V-W). The CUO
            radar detector installed at Pearl leaked badly. On surfacing
            tightened up on insulator clamp ring on dipole. Surface cruising
            as before zig-zagging during daylight hours.
0835 (V-W) Sighted U.S. Patrol bomber. Exchanged recognition signals (AC#1).
0948 (V-W) Changed base course to 290°T.
1145 (V-W) Changed time to conform with -11 (X) zone time.
1155 (X) Sighted U.S. Patrol bomber distance 20 miles bearing 050°T.(AC#2)
1320 (X) Sighted U.S. Patrol bomber distance 20 miles bearing 050°T.(AC#3)

19 February.
            Surface cruising as before. Seas moderately rough, wind and seas
            from NW, ceased zig-zagging.

20 February.
            Surface cruising as before.
1558 (X) Made quick dive to 350 feet to test for leaks. CUO installation
            leaked badly. No. 4 torpedo tube leaked slightly.
1655 (X) Surfaced. Resumed surface cruising.
2130 (X) Changed course to 240°T.

21 February.
0000 (X) Changed speed to one engine, 11 knots.
0730 (X) Sighted and exchanged recognition signals with aircraft escorts
            (two SBD's). Approached Midway channel entrance at two engine
            speed. (AC#4).
0800 (X) Sighted Midway Island.
0920 (X) Picked up Pilot and entered Midway channel. Moored alongside
            U.S.S. ARCHERFISH at Submarine Pier, Midway Island at 1030 (X).
1100 (X) Changed time to conform with + 12 (Y) zone time.
1000 (Y) Fueled ship to capacity. Received 15268 gallons of diesel fuel
            and took on 500 gallons of battery water. Made minor repairs to
            fuel oil purifier. The base upon investigation of CUO installa-
            tion found that the rubber gaskets used on dipole were incorrect
            in that they were too thick and of soft rubber and that the cable
            was shorted out. The base renewed the gaskets and reran the same
            cable that was used before. Not having time for a complete test
            of installation it is believed it will be of little use on this
            cruise. The base inspected No. 4 torpedo tube for leaks but could
            not find any.

(L) Radio

     Communications were satisfactory. Haiku's low frequency, 16.68 Kcs.
came in strength 5 until longitude 165°E. when it became unreadable. During
the daytime all frequencies were fair, 1439 Kcs. and 9090 Kcs. being the
best, 17,370 Kcs. faided out. A good daytime frequency on the 13 m.c. band
was found.

     At night 4525 Kcs. was by far the best frequency also very good nighttime
frequencies was found on the 8 m.c. band. At 1300 GCT, on station all fre-
quencies were poor with weak incoming signals and a high noise level. Poor
reception cleared up nightly by 1600 GCT. Heavy Jap interference was en-
countered on 4525 Kcs. at the beginning of each schedule.

     An average of two NPM serials were missed daily while operating sub-
merged. All Subpac serials were received.

     Ship-shore traffic was sent on 4235 Kcs., shore stations were very co-
operative and answered up immediately however the J-boys did all they could
to jam the frequency. As soon as we opened up as many as five of them gang-
ing up to create heavy interference by tuning their transmitter across the
frequency, keeping their keys depressed, or sending a series of very fast
dots. Maximum plate power and antenna current were necessary to break through.

     There were no major material casualties.

6 March. Trouble: Only small amount of grass on rangeland.
Remedy: Replaced two I.F. tubes in receiver (6AC7's).

26 March. - Trouble: PPI sweep flaring up brightly. This trouble began
30 March. occurring each morning after about 6 or 7 hours
op eration. Replacing V6 & V7 in PPI unit and V8
in range indicator unit, all on the video circuit
of the PPI, failed to correct it. PPI had to be
secured each morning that flaring up began. All
resistance readings checked and all voltage read-
ings except cathode of V4 in PPI unit, which was
high. R25 was observed to be excessively hot, indi-
cating high current thru deflection coils. Grid
bias circuit for V4 was suspected. Though resis-
tance and voltage readings checked fairly well,
it was thought that R28 in the -70V circuit might
be opening up when the set got too hot. R27 and
R28 both were replaced but the trouble repeated
itself.

Subject: U. S. S. PICUDA - Report of First War Patrol.

1. The first war patrol of the PICUDA was conducted
in the area between Latitudes 6° and 13° - 30' north and Longi-
tudes 137° and 150° east. Thirty-two of the fifty days on patrol
were spent in the area.

2. Area coverage was good. Persistent efforts to
increase coverage by more day surface patrolling were repeatedly
thwarted by enemy air coverage. It is to be noted that of some
twenty-six enemy aircraft contacts only one resulted in an attack
by the enemy and this was ineffectual.

3. There were five contacts with suitable torpedo
targets and all were aggressively developed into attacks.

Attack Number One resulted in the sinking of a large passenger
freighter with four Mark 18 torpedo hits following a well execut-
ed night approach at radar and periscope depth. Target was seen
to break amidships with stern in air at an angle of 45°.

Attack Number Two was a day periscope attack against a convoy
of four small AK's with three escorts. After obtaining a favor-
able firing position on one target, it was seen to zig towards
with zero angle on bow just prior to reaching firing bearing.
A quick set-up and firing of three torpedoes at a second target
resulted in three misses. PICUDA then conducted an end around
and while approaching on surface at night for another attack
was detected by an escort destroyer and subjected to gun fire
and later depth charges. Another end around and dawn submerged
approach failed due to inability to close range submerged. Fur-
ther action was thwarted by enemy aircraft and patrol vessels.

Attack Number Three was a day periscope attack on an empty tank-
er with two escorts. The tanker was hit with three, possibly
four, torpedoes. Target was seen to slow and later heard to stop.
During subsequent counter-attack target was heard to speed up and
clear area.

Attack Number Four was a night attack conducted at radar and
periscope depth against a passenger freighter with single escort.
Four torpedoes were fired at range of 1200 yards for two sighted
hits. Target was heard to break up and sink. Upon surfacing
only the escort was noted on SJ.

Attack Number Five was made on a convoy of two passenger freight-
ers escorted by two DD's. This attack was made at periscope depth
in early evening. Five torpedoes were fired at nearest target
with two sure hits. Target was seen after one minute to be listed
60° to port and about ten minutes later the characteristic break-
ing up noises were heard.

4. All contacts were developed in a determined fashion
and attacks were aggressively and efficiently executed. The suc-
cess of the single ping range just prior to firing is noted. The
excellent performance of the Mark 18 torpedo is most encouraging
and the remarks of the Commanding Officer in this regard are note-
worthy. The torpedo performance was excellent.

5. The morale of officers and crew and the material
condition of the PICUDA are excellent. Refit will be accomplished
in the normal period. A full investigation and report on the
faulty performance of main motor brushes will be made.

6. The Commanding Officer, officers and crew are con-
gratulated on this outstanding first patrol during which the fol-
lowing damage was inflicted on the enemy:

1. The first war patrol of the PICUDA was the first for
the Commanding Officer, as such. The patrol was conducted in the
open sea area North of the Western Caroline Islands.

2. In spite of active enemy air anti-submarine measures,
the PICUDA carried out excellent area coverage. This good area
coverage resulted in the contacting of six targets worthy of tor-
pedoes, in addition to that of a hospital ship. Five aggressive
attacks were made which resulted in inflicting severe damage to the
enemy.

3. Of note during this patrol were the following:

(a) Excellent performance of the Mark 18 torpedo.
(b) The good results obtained with the new camouflage.

4. This patrol is designated as successful for Combat

U.S.S. PICUDA Report of Second War Patrol.

(A) Prologue.

The U.S.S. PICUDA entered Advance Base Midway Island for refit and
recreation of personnel, April 5, 1944 after the first war patrol. For admin-
istrative purposes the PICUDA came under Commander Submarine Squadron Six and
Commander Submarine Division 61. The refit commenced April 6 and was complet-
ed April 19. April 20-21 were used for test of equipment and loading. There
was little change in personnel during this period, eight enlisted men were
transferred, replacements furnished by CSD-61, the officer personnel remained
the same. Operations and training under supervision of Training Command, Com-
mander Submarine Division 61, were conducted in Midway area April 22-25.
Training in diving, battle surface, day and night approaches and radar approach-
es were carried out. Five Mk XIV-3A exercise torpedoes were fired on practice
approaches with U.S.S. GREENLET as target screened by two escorts. Thirty One
rounds of 4"50 cal. were fired for indoctrination in day and night firing,
seventeen rounds of which were fired at target streamed by GREENLET. During
this training period the PICUDA conducted training with aircraft. Exercise
10B Tentative War Time Exercises. The period 26-27 April was used for loading.
April 28 PICUDA was ready for sea. Owing to receipt of orders that the ship
would join "Wolf Pack" and would be delayed the PICUDA volunteered to take
out for indoctrination training officers and enlisted men assigned by Train-
ing Command and to conduct training exercises with aircraft of Midway Island.
April 28, 29, 30 underway indoctrination training was conducted, a total of 25
officers and 37 enlisted men were taken out. While conducting this training,
Exercise 10E Tentative War Time Exercises was conducted with aircrafts. On these
exercises live two pound bombs were dropped. Much was gained by the officers
and crew of the PICUDA and it is hoped that others involved can say the same.
May 2 the PICUDA joined the Wolf Pack consisting of U.S.S. PERCH and U.S.S.
PETO. Commander F.W. FENNO, U.S. Navy came aboard PICUDA as Group Commander.
May 3 the Wolf Pack conducted training in Midway area. Ensign W.W. BEHRENS,
U.S. Navy reported aboard PICUDA for duty, assigned duty as Assistant Communi-
cation Officer. May 4 underway on second war patrol.

Patrol No.2

U.S.S. PICUDA
Time: 2026 Date: 6-4-44 Lat. 22° 00' N. Long. 119° 15' E.

Target Data - Damage Inflicted

Description: Target was leading of two medium sized widely separated
freighters accompanied by six small escort vessels. Initial
contact was periscope sighting of smoke shortly before sunset.
Visibility was very good.

Ships Sunk: None.

Ships Damaged: None.

Damaged determined by:

Target Draft: 15' Course: 030 T. Speed: 8 Range: 6000

OWN SHIP DATA

Speed: 3 Course: 157 T. Depth: 65' Angle: 0°

FIRE CONTROL AND TORPEDO DATA

Type Attack: Because of contact bearing on smoke in the early part of the
approach and nearly full moon rising, it was decided to stay
down for moonlight periscope approach. The target group
apparently took a large zig at twilight and it was impossible
to close the range sufficiently for a high power shot. Tor-
pedoes were fired in low power using the T.D.C.

(J) Anti-Submarine Measures and Evasion Tactics.

The Japanese continue to run large convoys well escorted by numerous
small escort vessels, destroyers, and sometimes cruisers. A escort carrier is
used in convoy to give air coverage. The submarine patrol area is well covered
by aircraft day and night, particularly along important shipping routes and in
focal points where the submarine might be. These patrol aircraft may be any
type of plane equipped with radar. Radar is used by surface ships in the con-
voys. The depth charge has been increased in size and may be termed as "block
busters". These block busters are used in patterns with the normal size charges.
Depth at which the depth charge explode are 50 to 100 feet, 150 to 200 feet and
250 to 300 feet, the first pattern dropped being set at the shallow depth, other
patterns are set for deeper depth as the attack progresses. The practice of con-
tinuous use of echo ranging has been abolished and listening only is used with
little echo ranging thereby leading one to believe that the Japanese has im-
proved his underwater listening equipment. The sampan, junk, fishing boats, etc.
continue to be used as patrol craft.

(L) Radio

NPM was copied throughout the area without undue difficulty. Fre-
quency coverage was sufficient. Ship-shore traffic was sent on the 4235
series.
NKN broadcasts of China Sea Army Air Forces contact reports were
received at various times with daily repeats at any time between 1600 and
1900 G.C.T. During the fifteen days this frequency was guarded the average
number of messages sent daily was two. Transmission was either by hand
key or automatic tape with each group repeated twice. Reception was good.
Decoding was accomplished with CSP 1500 and effective key list.

Intra-group communications were scheduled on a rotating plan with
one high frequency voice and one low frequency C.W. effective at all times.
Of these the high frequency voice was used almost exclusively, in general
C.W. was unsatisfactory. Both the submarine code furnished and CSP 1270
series were used, the latter when an additional submarine not having the
submarine code was ordered to the group. Communication training was con-
ducted enroute the area since this group had only one days training together
prior to departure on patrol.

The only radio material casualty was a reduction in the output of
the IF side of the TBL-7 towards the end of the patrol which was traced to
the Antenna Coupling Coil L-27.

(M) Radar.

A. SJ-1

The SJ-1 radar has operated quite satisfactorily this run. Ranges on
targets and on islands have been good, the longest being 85 to 90 thousand
yards on MINAMI IO SHIMA. Several times around southern part of FORMOSA how-
ever, false pips appeared ranging from 8 to 35,000 yards. These pips were
not caused by faulty radar operation as definite true bearing and ranges were
obtained. They must have been atmospheric phenomena of some sort, for the
pips were not distinct enough to be ships nor fuzzy enough to be rain squalls,
and they would fade out when the range closed to about 3000 yards. No rain
clouds were in the vicinity of the pips, only light, misty clouds.

Material troubles were few and minor, most of them appearing near the
end of patrol.

(a) Focus on range indicator ineffective. Replaced LP1 (991).
(b) Sweeps jumping up on range indicator and flaring up on P.P.I.
The I.F. cable had an intermittent short on transmitter end of
cable. Repaired cable.
(c) No sweeps on range indicator; all lamps (991) unlit. Replaced
rectifier tube V10 (2 x 2).
(d) Jittery sweeps on range indicator; low voltage on regulated
rectifier No. 2. Replaced the rectifier tubes (5U4G)

B. SD-4

The SD-4 has not operated to complete satisfaction this run. The
average plane contact has been at 10 miles as opposed to 15 on our first run.
Material troubles have been frequent.

(a) Sweeps bent down at left end. Changed antenna coupling.
(b) Jittery sweeps - jumping up and down. Replaced 8014's.
(c) Sweep ' appearing shortly after set turned on. Replaced
cathode ray tube (905).
(d) No transmitted pulse or grass. Replaced one of receiver
R.F. amplifier tubes (9001).
(e) Jittery sweeps - jumping right and left. If plate variac is
turned down to 50-55 where meter reads 6 mils, jumping ceases.
Replacing 8014A's, the 8013, the 1960 tubes in transmitter, the
sweep tubes in receiver-indicator, trying various settings of
grid resistor and synch transformer switches, and re-adjusting
the tuning - all failed to remedy the situation. As time passed
the jumpiness decreased, allowing the plate variac to be turned
up to 60-65 for a meter reading around 8 mils.

U.S.S. PICUDA - SECOND WAR PATROL.

From:             The Commander Submarine Force, Pacific Fleet.
To :              The Commander-in-Chief, United States Fleet.
Via :             The Commander-in-Chief, U. S. Pacific Fleet.

Subject:          U.S.S. PICUDA (SS382) - Report of Second War Patrol.
                  (4 May to 27 June 1944).

                  1. The second war patrol of the PICUDA was conducted in
the South China Sea. The PICUDA was one of a coordinated attack
group.

                  2. The PICUDA participated in three aggressive torpedo
attacks, and inflicted severe damage upon the enemy. In addition, the
PICUDA was subjected to severe depth charge attacks.

                  3. It is noted that of the seven contacts made, three were
hospital ships.

                  4. Heavy enemy air activity in this area is undoubtedly
due to the severe losses the enemy has sustained there during recent
months.

                  5. Information received from the report of the GUITARRO
(SS363) indicates that in the attack made by the PICUDA on 2 June,
one of the vessels hit was seen by the GUITARRO to be burning fiercely
and, thus, is considered destroyed.

                  6. This patrol is designated as "Successful" for Combat
Insignia Award.

                  7. The Commander Submarine Force, Pacific Fleet, congratu-
lates the Commanding Officer, officers, and crew for this successful
patrol. The PICUDA is credited with having inflicted the following
damage upon the enemy:
                                  S U N K

1 - Passenger Freighter (class unknown)- 7,000 tons (Attack No. 1)
1 - Escort Vessel (class unknown)      - 1,000 tons (Attack No. 1)
1 - Freighter (class unknown)          - 5,000 tons (Attack No. 2A).
                                  TOTAL - 13,000 tons

(M) Radar.

(a) SJ-1

Obtained SJ-1 ranges from 60 to 80 miles on taller peaks of FORMOSA and
LUZON. These excessive ranges were discovered when we ran thru pips without
finding anything. Varying the pulse rate caused the pips to change their range,
indicating they were echoes appearing on the sweep following the one triggered
off by their own transmitted pulse.

A radio key was installed in the primary of the high voltage transformer,
and wired to the I.F. jack on the receiver-indicator so that ear phones could
be plugged in. Transmission of identification signals was possible at ranges
up to 10 miles.

Before leaving MIDWAY the Meacham Range Unit failed to operate and a re-
placement of the entire unit was made by the PROTEUS.

(b) SD-4

SD-4 ranges on planes averaged 20 to 30 miles except for low-flying planes.

The SD mast was bent when an inexperienced operator failed to lower it soon
enough when making an 18 knot dive. It stuck in the raised position after that,
though stoning the mast and greasing it nightly kept it operating to a certain
extent.

At SAIPAN the mast was pulled by the HOLLAND and on re-installing, it was
found that the inner conductors were bent and shorted to each other. The
BILLFISH'S mast was eventually installed.

(c) APR-1

The APR-1 worked much more satisfactorily than the CUC, but is useless
when the SD is on. It picks up noise from the SJ even though the latter is far
outside its frequency range. No enemy radars were encountered. The only noises
obtained were from the SD, the SJ, and the TBL.

(N) Sound and Sound Gear.

          Satisfactory results were obtained with both the JK-QC and QB. Strong
currents were encountered in both the BASHI and BALINTANG CHANNELS and sound
conditions were poorer in these waters than in the rest of the area.

          After the typhoon, sound conditions were noticeably improved. It is
believed that the mixing of water caused by the typhoon and resultant decrease
in temperature gradients was largely responsible for the improved conditions.
This conclusion is substantiated by bathythermograph cards taken.

          Pinging heard at an approximate range of 26,000 yards on 25 August
was our first indication of a large Convoy. Screws were heard on this same date
on the JK-QC gear at ranges up to 13,000 yards.

          Two attacks in the presence of fast anti-submarine vessels were made
without the use of the JP-1. A definite "motor-boating" noise was experienced
in phones when plugged in jack. It was localized to amplifier and extensive
tests were taken but ships company failed to eliminate the trouble.

                                                                - 40 -

comments on.

1. The third war patrol of the PICUDA in the LUZON STRAITS
area lasted 72 days of which 31 days were spent in the assigned area.
The above includes a round trip to SAIPAN for reload and minor repairs.
PICUDA was one of a coordinated attack group consisting of PICUDA,
SPADEFISH, and REDFISH, with the Commanding Officer of the PICUDA,
Commander G. R. DONAHO, acting as O.T.C.

TORPEDO ATTACK #1.
A smoke contact was developed into a well screened con-
voy of 10 ships hugging the northern coast of LUZON. Six fish were
fired at two medium AK's with one hit ringing the bell for the second
AK.

TORPEDO ATTACK #2.
A three torpedo "down the throat" attack on an escort
gunboat, PG(E)-1 class, with a depth setting of 2 feet was unsuccess-
ful except to reduce the supply of Nip depth charges available.

TORPEDO ATTACK #3.
This was a daylight attack on an 8 ship convoy with at
least 3 escorts and an air screen. Four torpedoes were fired at a
medium AK resulting in 3 hits, and one torpedo fired at each of two
additional AK's both of which found their mark. Irregular and in-
effective depth charging resulted, probably due to extreme respect
for our submarines marksmanship.

TORPEDO ATTACK #4.
Another convoy was picked up hugging the northern coast
of LUZON and in an early morning attack four torpedoes were fired at a
medium AK getting 2 hits to sink her. Two more torpedoes were fired
at a large 2 stack AP which apparently absorbed them and though severe-
ly crippled she managed to continue on her way. It is noted here that
a typhoon came up the following morning which may have finished the job
the PICUDA had started on this valuable ship.

        2.      This most satisfactory patrol is another feather in
the cap of the PICUDA's temporary commanding officer who has a long
list of successful missions against the Japs to his credit.

        3.      The PICUDA returned from patrol in very good condition
and should refit in the normal period. The health and morale of
officers and men appear excellent after such a long and exciting
patrol.

        4.      It is noted that no enemy radar was encountered but
that air coverage of the area and convoys was greatly intensified.

        5.      The Commanding Officer, officers and crew are most
heartily congratulated on this aggressive and highly successful patrol
in which it is recommended that damage to the enemy be credited as

U.S.S. PICUDA - THIRD WAR PATROL
AND REPORT OF ELEVENTH COORDINATED

From: The Commander Submarine Force, Pacific Fleet.
To : The Commander-in-Chief, United States Fleet.
Via : The Commander-in-Chief, U.S. Pacific Fleet.

Subject: U.S.S. PICUDA (SS382) - Report of Third War Patrol and
Report of Eleventh Coordinated Attack Group. (23 July
to 3 October 1944).

1. The third war patrol of the PICUDA, and the Eleventh
Coordinated Attack Group was conducted in the area between Formosa
and Luzon. The group consisted of the PICUDA, the U.S.S. SPADEFISH
(SS411), and the U.S.S. REDFISH (SS395) with Commander G. R. Donaho,
U.S. Navy, Commander Submarine Division 222, as the Group Commander
and temporary commanding officer of the PICUDA. Further details will
be found in the SPADEFISH's and REDFISH's first war patrol reports.

2. This splendid patrol is in keeping with the outstanding
record of the PICUDA and a continuation of the illustrious record of
the temporary commanding officer who has six previous successful pa-
trols to his credit as the commanding officer of the U.S.S. FLYING
FISH (SS229). The effectiveness of the helpful exchange of informa-
tion by the submarines of the group and aggressive performance of the
individual submarines is best told by the great damage inflicted upon
the enemy. All three submarines replenished torpedoes and made minor
repairs at Saipan midway through this patrol.

3. The PICUDA was plagued with two typhoons and many enemy
aircraft contacts. She was fortunate enough, however, with skillful
area coverage, to contact four large convoys all of which were aggres-
sively attacked and severely damaged.

4. This patrol of the PICUDA is designated as "Successful"
for Combat Insignia Award.

5. The Commander Submarine Force, Pacific Fleet, congratu-
lates the group commander and commanding officer, officers, and crew
of the PICUDA, and the commanding officers, officers, and crews of the
SPADEFISH and REDFISH for this outstanding patrol, a fighting job well
done that dealt a severe blow to the enemy. The PICUDA is credited
with having inflicted the following damage upon the enemy during this
patrol:

0840 Periscope depth. Discovered we were leaving trail of bubbles
from main ballast tank blows. Remained submerged to grind in
master blow valves, and to work on SJ, which gave trouble again
last night.
1803 Surfaced. Proceeding to lifeguard station.

21 November.
0430 (I) On lifeguard station.
1000 Seas Force 6.
1008 Sighted first B-29 passing overhead.
1050 to
115 Sighted 9 more B-29's and one Jap interceptor.
1130 Master gyro out, steering by magnetic.
1315 Sighted BETTY bearing 060 (t), distant 10 miles, headed toward
us. Submerged. All our planes clear of target area, so remained
submerged to check master gyro and get auxiliary gyro settled.
1645 Master gyro in commission. Surfaced.

22 November.
0923 (I) Surface patrol across probable route of SEALION'S task force.
0937 J.O.C.D. sighted 5 planes in formation, closing. Submerged.
0950 Investigation showed planes had movable wings. Surfaced.
1320 Changed course to head for SAISHU STRAITS.
1644 Sighted BETTY bearing 145 (t), distant 12 miles. Did not sight
us. Crossed astern.

23 November.
0015 (I) Patrolling islands of Korean Archipelago.
0018 JK heard pinging 340 (t).
SJ contact 18,000 yards. Numerous islands made it difficult to
distinguish targets.
0020 Commenced tracking.
0130 Dodged trawler on our track.
0310 Battle Stations Radar. At this point we had reached position
roughly broad on starboard bow of convoy. Their speed was check-
ed 8.5 knots, base course 080 (t), which followed general line of
coast. Convoy appeared to consist of four or five ships, with two
escorts on starboard flank, whereabouts of other unknown. Started
in to attack, using slow speed to avoid phosphorescence (10 knots) intending
to reach firing position 2,500 - 3,000 yards on starboard beam
firing ahead or astern of rear escort as situation dictated.
At about 6,000 yards we could make out four ships in loose column;
one medium AK, two large AO's and another medium AK. Second
escort had dropped astern so we were forced to go between the two.
Kept silhouette as small as possible to nearer escort (a new PG-E)
And headed for us, while range to targets was still over 4,000 yards,
O.O.D. sighted two more escorts astern of convoy. Evidently we
had arrived while they were changing formation subsequent to clearing
the restric-
ted waters of the Korean coast. PPI had not picked them up due to
ted water.

Time: 0640 (I) Date: 23 November 1944 Pat. 34-15N. Long. 128-58E.
Target Data - Damage Inflicted

Description: Target was one of the AO's of th. second attack. Only this AO,
one of the AK's and one escort were present. Initial contact
made by periscope on smoke. Visibility good.

Ship Sunk: One large AO, 500 feet long (by binocular formula), similar to
RIKKO MARU, 9,000 tons.

Ship Damaged: None.

Damage Determined by: Two torpedo hits, 1 minute and 57 seconds and 2 minutes
and 07 seconds after commencing firing, followed by loud break-
ing up noises heard through the hull throughout the boat and on
sound gear. Target's screws stopped when hit and never started
again. Four loud explosions from target were subsequently heard
throughout the boat, sounding like target blowing up. Persist-
ent depth charging prevented taking a look.

Target Draft: 15 ft. Course: 154 (t). Speed: 3.5 kts. Range: 1,500 yards.

Own Ship Data

Speed: 3 kts. Course: 250 (t). Depth: 66 ft. Angle: 1½° down.

Subject: U.S.S. PICUDA - Report of War Patrol No. Four.

1. War Patrol Number Four of the U.S.S. PICUDA, the
first for the Commanding Officer as such, was conducted in the
northern part of the East China Sea, as one of a coordinated
attack group consisting of U.S.S. QUEENFISH, U.S.S. BARB, and
U.S.S. PICUDA, Task Group Commander Commanding Officer, U.S.S.
QUEENFISH. It was of thirty-six days duration, twenty-two days
of which were spent on station.

2. The following attacks were delivered:

No. 1 - Contact was initially established on echo ranging
in the late afternoon of 17 November, 1944, with two large oilers,
one freighter and four large freighters, in two columns. PICUDA
gained an attack position on the column of freighters, so close to
the leading one of two flank escorts that it blocked the field of
vision when the periscope was raised for a final set-up. When the
range was clear, PICUDA fired two salvoes of three torpedoes at
each of the two leading freighters in the near column, with the
second oiler in the far column nicely filling the interval between
them. Firing was commenced at a range of 2,100 yards, with 320°
gyros, on a 90° port track. Four distinct torpedo explosions were
heard, timed to indicate two hits in second freighter in near
column and two in second oiler in far column. These were followed
by breaking up noises in the direction of the second freighter.
Three of the five escorts then persistently held PICUDA down in
30 fathoms of water for some two and a half hours. Shortly after
surfacing (about four hours after the attack), PICUDA saw mani-
festations of other submarines' attacking the same convoy and a
very large explosion at the approximate point at which the oiler
was hit.

No. 2 - Fifteen miles off the southeast coast of KOREA,
PICUDA made radar contact at 18,000 yards just after midnight on
23 November 1944, on a convoy of a medium freighter, two large
oilers and a second medium freighter in loose column. It is
interesting to note that here again echo ranging contact was first
made three minutes before radar showed a pip. After almost three
hours of tracking, PICUDA commenced the attack phase from the
convoy's starboard bow, unfortunately having chosen a moment when
the escorts were changing disposition. She fired six bow tubes

at a point of aim consisting of overlapping bow and stern of two
rear targets at a range of 3,000 yards, 012° gyros, on a 90°S
track, the torpedoes running between the two near flank escorts,
one of which was 1,100 yards on PICUDA's starboard bow, the other
being 1,500 yards on her port bow. With two additional escorts
closing from stern and to starboard of the convoy, PICUDA held
the initiative, turned and fired her stern tubes, and retired at
flank speed with escorts on either quarter.
No. 3 -
After standing clear of the formation in the above
attack, PICUDA reloaded and submerged on convoy's track. At
0750 (I), two ships of the convoy, one freighter and one oiler,
escorted by one PC, were sighted and approach was begun. After
PC was allowed to pass close aboard ahead, the four remaining bow
torpedoes were fired at the oiler in the van at a range of 1,500
yards, 356° gyros, 88°P track. Two hits were heard, but loss of
depth control prevented getting off stern tubes at the freighter.
No. 4 - On the early afternoon of 26 November 1944, off
HIRADO SHIMA, this submerged attack was made on a lone small
coastal tanker. Two torpedoes, with depth set four feet, were
fired at a range of 1,350 yards, 184° gyros on 122°P track. As
no hits were obtained, it is presumed that the torpedoes ran under
the target despite four foot depth setting.

3. The patrol was characterized by the amount of enemy
air activity, and by the cool and aggressive manner in which the
Commanding Officer pressed home his attacks. It is particularly
gratifying that he was able to play his position so well on the
QUEENFISH - BASS - PICUDA team, which is a winning combination.

4. The recommendation that each submarine be assigned
a call on the lifeguard circuit is concurred in.

5. PICUDA is in good material condition and will be
given normal profit by U.S.S. SPERRY, and Division 101, while her
crew recuperates at Camp Dealey. Her Commanding Officer, officers
and crew are to be warmly congratulated upon the success of this
patrol.

6. It is regretted that on the aggressively conducted
first and second attacks, it was impossible to obtain more posi-
tive evidence of damage. It is recommended, however, that PICUDA
be credited with having inflicted the following damage upon the
enemy:

SUNK
1 large AK (EC) 7,500 tons
1 large AO (EU) 10,000 tons

            efficiency, so composition of convoy, number of escorts, etc. is
            doubtful. Has at least three large ships. Dim moonlight through
            heavy overcast. Intermittent rain and mist. Sea force 5 to 6.
0515        Looked for a bigger formation.
0516        Changed course to eastward, putting us directly on flank
            train. C.O. was able to creep out again and regain position on flank
            before midnight. Too rough for submerged attack, even if we
            could. C.O. said he has waited two weeks for this opportunity,
            so he is determined to get at anything we could see.
            Encountered communication between two columns. Passed one escort
            and ran into port at 2,500 yards. Could make out the AK
            did not. Radar suddenly slacked off, and dead ahead was the stack
            machine of about 8 - 9,000 tons, angle on the bow 80 starboard,
            range about 1,800 yards, and beyond him and almost overlapping,
            two large AK, 3,000 tons, angle on the bow 70 starboard. A DE escort appeared
            for a short while, assisting us and apparently patrol-
            ing the usual route. Thought our goose was cooked but it
            was not. We hit and heavy underwater explosion in AP followed by
            two more hits in AK (seen by O.O.D.). Pressed A about 600 yards
            to starboard. He was almost dead in the water when we passed
            and leaning on the whistle lanyard for all he was worth; C.O.
            watching escaping steam in fascination. Conning tower personnel
            heard whistle and mentally added a plane zooming us to the

USS PICUDA (SS382) - Report
of Fifth War Patrol.
From: The Commander Submarine Squadron FOUR.

Via : (1) The Commander Submarine Force, PACIFIC
FLEET, Administration.
(2) The Commander-in-Chief, U.S. PACIFIC FLEET.

Subject: U.S.S. PICUDA (SS382) - Report of Fifth War Patrol.

1. The fifth war patrol of the PICUDA, was conducted in
the East China Sea and Formosa Straits area, where twenty-six
days of this forty-nine-day patrol were spent. The PICUDA, along
with the BARB and QUEENFISH, formed a coordinated attack group
with the Commanding Officer of the QUEENFISH, Commander C. E.
LOUGHLIN, U.S. Navy, as Group Commander. Upon the QUEENFISH
departing the area, the Commanding Officer of the PICUDA, Com-
mander E. T. SHEPARD, U.S. Navy, became Group Commander. The
patrol was terminated by expenditure of all torpedoes.

2. Four ship contacts suitable for torpedo fire were
made, and three of these were developed into attacks. The fourth,
a large AK, could not be closed submerged, and in view of the SJ
radar being out of commission and disassembled, thereby blocking
the conning tower hatch, the Commanding Officer elected to reas-
semble and repair it before attempting a surface end around. Due to
poor visibility upon surfacing the contact could not be regained.
Summary of attacks, all made with Mark 18 torpedoes, follows:

Attack No. 1, 7 January 1945: Acting on a contact
report from the BARB, PICUDA closed a convoy of three ships with
at least two escorts and made a daytime periscope attack. Two
of three torpedoes caused a large tanker to sink, the sink-
ing being witnessed by the BARB.

Damage Assessment: Sunk - 1 AO(LU), 10,000 tons.

Attacks Nos. 2 and 3, 8 January 1945: Again acting
on a contact report from the BARB, PICUDA made an end around, ob-
taining a favorable attack position. PICUDA witnessed the lead-
ing ship of the convoy blow up as result of BARB's attack. In a
very aggressive night surface attack the PICUDA slipped between
two escorts and fired three bow tubes at each of two large
freighter-transports, resulting in one hit in each. PICUDA then

U.S.S. PICUDA - FIFTH WAR PATROL.

From:           The Commander Submarine Force, Pacific Fleet.
To :            The Commander-in-Chief, United States Fleet.
Via :           The Commander-in-Chief, U.S. Pacific Fleet.

Subject:        U.S.S. PICUDA (SS382) - Report of Fifth War Patrol
                (5 January to 15 February 1945).

        1.      The fifth war patrol of the PICUDA, under the command
of Commander E. T. Shepard, U.S. Navy, was conducted in the Formosa
Straits and East China Sea areas. The PICUDA, along with the BARB
and QUEENFISH, formed a coordinated attack group with the commanding
officer of the QUEENFISH as group commander. Upon departure of the
QUEENFISH after expending all torpedoes, the commanding officer of
the PICUDA acted as group commander.

        2.      As previously stated in the patrol reports of the
QUEENFISH and BARB, this fighting group of submarines continued to
inflict severe damage upon the enemy in the same daring fashion which
characterized their previous patrols as a group. The PICUDA, in ad-
dition to a gun attack on a small craft, delivered four aggressive
torpedo attacks which resulted in great damage to the enemy. The
eight-ship convoy attacked by this group on 7-8 January, with the ex-
ception of one ship, was completely demolished. The PICUDA was for-
tunate enough to contact another sizeable convoy on 29 January and
obtained six hits out of ten torpedoes fired in three ships.

        3.      Award of Submarine Combat Insignia for this patrol is
authorized.

        4.      The Commander Submarine Force, Pacific Fleet, congra-
tulates the commanding officer, officers, and crew of the PICUDA for
another outstanding aggressive patrol. The PICUDA is credited with
having inflicted the following damage upon the enemy during this pa-
trol:

U. S. S. PICUDA Report of Sixth War Patrol.

0555 (H) Five ships in sight, three medium AK's, one small, engines aft,
AK, and one medium AP-AK. One WAKATAKE DD ahead of convoy, three
DE's on our side, unknown escorts on other side. Using minimum
speed and one foot of periscope.
0606 Fired tubes 1, 2, and 3 at two overlapping AK's. No hits.
Shifted to engines aft but before we could fire remaining tubes
we were headed down. Couldn't hold her, so leveled off at 200
feet, rigged for depth charge, and awaited the inevitable. (Loss
of depth control due to too long a poppet opening. C.O. made
mistake of cautioning forward room about impulse bubbles. Should
have known better).
After a heated post mortem, I believe what happened was this:
(1) escort sighted our wake, periscope, or just had a hunch.
(2) escort dropped one depth charge meaning "ALL STOP".
(3) had the escorts continued pinging, others listened for us.
(4) when we fired, targets were actually making 4 knots or less.
(5) minimum periscope exposure gave poor data to TDC.
(6) bearings indicated targets had slowed, but we didn't slow
them enough on TDC.
(7) We just got outsmarted, and missed by a mile.
0615 Depth charging commenced. Evading at 2/3 speed under a beautiful
ten degree gradient.
0638 Crackling and rumbling on sound gear bearing 060(t). Rumble
audible through hull.
0710 Loud but not close pattern of 14 charges.
0807 Secured from depth charge. Pumped down the forward swimming
pool, reloaded and came to periscope depth.
0934 While preparing to surface, heard two series of explosions,
three per group in rapid succession - probably bombs. Visi-
bility varying rapidly.
1150 Surfaced. Visibility 100 yards to 4 miles due to intermittent
fog and mist.
1200 Latitude 34-10N - Longitude 123-49E.

0654 (H) Sighted junk 326(t), distant 5 miles.
1200 Latitude 34-20N - Longitude 122-45E.
1704 Sighted junk on horizon bearing 020(t). Closed in, stopped him
with 20mm and went alongside to exchange sea stories. Eight
Chinese and a load of produce. Gave them a few canned goods in
exchange for many kow tows. Resumed patrol.
2225 Sighted sampan close aboard. Avoided.
2304 Received message from ComSubsPac designating us for lifeguard
duty.

Remarks: Reason for misses is believed to be due to target's stopping.
Target tracked at 10 knots for sixty (60) miles or more while on surface.
Uncertain ranging and target discrimination due to rapidly closing visibility
after diving made further speed analysis doubtful. Sound was unable to pick
up any screws. Number 3 tube outer door had to be opened by hand after shear
pin on interlock chain snapped when hydraulic pressure was applied. Cause
for breaking undetermined as proper procedure was carried out by torpedomen.

CONFIDENTIAL                       U. S. S. PICUDA Report of Sixth War Patrol.

Number 1 Main Motor Brushes - During routine inspection, trouble was found in the brushes for Number one main motor in the leading rows. The brushes were found to have bad pigtails and chipped faces, and from appearances, the brushes seemed to be harder at the toe than at the heel. The defective brushes were the latest type "USN" brushes installed just prior to this patrol. They were replaced and no further trouble occurred.

On a dive on 15 May there occurred a casualty in the main cubicle. In shifting the Bus Selector to Batt Bus on the diving alarm, when the bus selector contacts opened, and instantaneously thereafter the protective arcing contacts, an arc of sufficient force was drawn to throw particles of copper on #2 generator rheostat resistance coil (Type TM Item 49) thus short circuiting it. Smoke was observed immediately and at the same time it was noticed that #2 generator field meter read three amperes. The field circuit then was cut out.

To prevent a recurrence of a similar accident and in view of the problems of replacing a generator resistor, it is recommended that a protective flame resistant insulation be inserted under each group of generator resistors.

2. Ordnance and Gunnery.

No major defects or damage was experienced.

(L) Radio.

No serious material casualties occurred. Reception was excellent while on station, as well as the period spent in transit to and from station. The existing frequency plan on the NPM FOX schedules is quite adequate. Some fading was experienced on all frequencies but given proper considerations was not too annoying. Transmissions were conducted successfully; NPM (Radio Guam) and ZAM (U.S.S. CHICAGO) heard our signals with a signal strength -5 (very loud). NPN-4 and ZAM cooperated to the fullest extent by relaying traffic for us. Some difficulty was experienced during transmissions to NDF-4 (U.S.S. ORION) using 155. By using the second harmonic of this frequency (8310) our transmissions met with favorable results. All Roll-Pack transmissions were successful, except to U.S.S. LIONFISH.

Modification to RAL-6 Receiver: Removed L-11 in first RF circuit. This coil shorted against the receiver cabinet and burned out completely as well as R-101 in the suppressor grid circuit of the first RF tube. Replaced this resistor and fed antenna directly into L-101 RF coil. Reason for the modification was that we had no replacement for L-11. Receiver operating satisfactorily.

TBL-7 Transmitter: Replaced first stage Intermediate Amplifier Tube, Type 860. Tube had become gassy and created flash-back across keying relay terminals.

3. I.F.F. gear operated satisfactorily when used. In most cases
while in the area no U.S. planes encountered had their ABK's turned on. No
material casualties encountered.
4. The APR and SPA operated satisfactorily. Numerous enemy radars
were encountered. Several times the first indication of enemy aircraft was
via the APR. Only material casualty was the transformer in the SPA, which
shorted out and had to be replaced. See section (U), Radar Countermeasures,
for comment on an arrangement whereby the SPA might be used to analyze SJ
radar interference.

(N) Sonar Gear and Sound Conditions.

All sound gear gave good performance without any serious material
failures. Sound conditions in the areas were fair, depending mostly on the
bottom in the vicinity.
JP-1 Sound Gear: Replaced voltage regulator tube 3-38. Failure
of this tube was traced to a power surge during battery charge. Corrected
failure due to broken leads on lead from hydrophone to receiver proper. Re-
placed Phenolic Plugs J-101 and 102. This trouble due to hard usage during
charging hydrophone before each operation period.
WCA Sound Gear: Replaced one amplifier tube. Tube was micro-
phonic. Any other repairs on this gear were simple repairs such as replacing
fuses and panel lamps.

(O) Density Layers.

In the vicinity of KII SUIDO the curves obtained were isothermal.
However, all cards taken in Area 12 showed good to excellent negative tempera-
ture gradients. The sharp break in the gradient usually was found at 60 to
90 feet keel depth. The gradients were from 3 to 10 degrees.
Fifty-one (51) bathythermograph cards were submitted to the Hydro-
graphic Office, Washington, D.C.

(P) Helath, Food, and Habitability.

The health of the crew has been excellent. There were no serious
diseases or injuries. The water supply has been adequate both as to quantity
and quality. Toward the latter part of the patrol, difficulty in maintaining
a balanced diet was encountered. The lack of fresh frozen fruits and vege-
tables was most noticeable.
On 6 May 1945, five survivors from a crashed B-29 were received
from the U.S.S. SCABBARDFISH for transportation to SAIPAN. One had sustained
a compound fracture of the left tibia and fibula.
The habitability of the boat was satisfactory throughout the
patrol.

3. Sonar - No Unusual measures were encountered.

(V). Remarks.

This patrol was disappointing to all hands, having resulted in
little if any concrete damage to the enemy, but at the same time having
been unusually wearing on all hands due to night flying planes, numerous
floating mines and shallow water.
The refit given the ship by Submarine Division 46 and the
Submarine Base Pearl was most gratifying. With one outstanding exception,
this patrol was marked by surprisingly few material failures. The both
newly installed equipment and that which was overhauled functioned well
throughout the run.
The exception noted above was in the main engine work. Several
liner failures were experienced, and numerous minor troubles were encounter-
ed which were unusual for these normally trouble free engines. Some of this
is undoubtedly due to the hard usage the engines received on the preceding
patrol, but instances of nuts set up hand tight, unequal tension in holding
studs, etc. seem to indicate inexperienced or careless overhaul work.

Subject: U.S.S. PICUDA (SS382) - Report of War Patrol Number Six -
Comments on.

1. The Sixth War Patrol of the U.S.S. PICUDA was conducted in
KII SUIDO from 2 April to 17 April 1945, and in the Yellow Sea from 22 April
to 4 May 1945. Twenty-eight days were spent in the enemy area, seventeen
submerged.

2. This patrol was characterized by five ship contacts, one of
them resulting in an unsuccessful attack, sighting of a normal number of
planes, many mines sighted of which 18 were sunk or destroyed by gunfire,
considerable enemy radar activity including that from night planes, hazar-
dous shallow water operation.

3. The one attack was made on 28 April 1945. A convoy of five
ships and six or more escorts was picked up by radar at 66 miles; most
abnormal. A day submerged attack was made in a flat calm sea. Three mark
18 torpedoes were fired at two overlapping AKs at 2400 yards range on 75
track, small gyro angles, depth set 6 feet. Target speed used 9 knots.
All three torpedoes missed. The depth control was faulty and this prohib-
ited further attack as the ship went deep. The Commanding Officer's reason
for the misses was that the submarine was detected when near the firing
point and the targets stopped.

4. The PICUDA now goes to Navy Yard Overhaul on the West Coast.

5. The Division Commander congratulates the Commanding Officer,
officers and crew upon their safe return from this hazardous patrol. Better
luck next time.

Via : The Commander in Chief, U. S. Pacific Fleet.

Subject: U.S.S. PICUDA (SS382) - Report of Sixth War Patrol
(15 March to 20 May 1945).

1. The sixth war patrol of the PICUDA, under the command of Commander
E. T. Shepard, U. S. Navy, was conducted in the areas off Ki Suido and in the
northern China Sea. During the patrol the PICUDA joined the coordinated attack
group of which the commanding officer of the TRUTTA was group commander. Life-
guard services were rendered in addition to offensive patrol.

2. This well conducted patrol netted few contacts, most of which could
not be closed for attack. One attack was made on a convoy, but proved unsuccessful,
probably due to radical change in target speed. Another attack caused possible
damage to a destroyer. The Force Commander hopes that the PICUDA will be favored
with better luck next time.

3. Award of Submarine Combat Insignia for this patrol is not authorized.

4. The Commander Submarine Force, Pacific Fleet, congratulates the
commanding officer, officers, and crew of the PICUDA for the completion of this
patrol. The PICUDA is credited with having inflicted the following damage upon the
enemy during this patrol:

In accordance with Commander Task Force Seventeen Secret Operation Order No. 146-44 the U.S.S. PETO and PITCH departed Pearl Harbor at 1330 28 April 1944. Enroute Midway these boats exercised at communication drills and individual training. Arrived Midway at 0800 2 May 1944 where U.S.S. PICUDA joined the group. May 2nd was devoted to instruction in doctrine and procedure for the patrol. May 3rd 1944 exercised all boats in communications attack doctrine and patrol procedure. At 1330 4 May departed Midway for patrol area, Group Commander in U.S.S. PICUDA, U.S.S. PITCH had Doctor Remey on board for further transfer to the U.S.S. HALIBUT at rendezvous Northeast of Marcus Island.

Enroute to special patrol area exercised all boats in communications and PERCH
effected transfer of Doctor Ramey to HALIBUT. The cruising formation West as
far as Wake Island was in column, distance between boats seven miles with PERCH
leading boat, PICUDA second and PETO third. On reaching Longitude of Wake opened
distance between boats to twenty miles. Voice communication remained good and
the group continued on at 10 knots into special area northwest of Guam.
During the period 12 to 14 May sighted two small patrol boats and dived five
times for planes.

At 2000 14 May received ComSubPac serial Three changing patrol area to
Eleven Dog.

15 to 18 May enroute to patrol area. Communication by voice during this
period was poor because of static caused by electrical storms. During night of
18 May PERCH and PICUDA entered Bashi Channel. A patrol area was established
across the western entrance to the Bashi Channel south of Takao with PICUDA to
patrol north and south along the 120th Meridian; PERCH along a line fifteen miles
west of PICUDA and PETO along a line 15 miles east of PICUDA.

19 May at 0530 PICUDA sighted masts of ship which turned out to be a
hospital ship. Lat. 21° - 10' N. Long. 120° - 40' E. Proceeded submerged
through Channel during day sighting fifteen patrol and fishing craft plus seven
planes. Bashi Channel seems to have pretty fair air patrol. 1900 Surfaced, pro-
ceeded to Longitude 120° E. and commenced surface patrol on course 180°T. at 9

Via : The Commander-in-Chief, U. S. Pacific Fleet.

Subject: Patrol Report of Commander Task Group 17.14.

1. This, the fifth coordinated attack group, conducted
its patrol in the South China Sea around Formosa.

2. The group consisted of the U.S.S. PICUDA (SS382),
the U.S.S. PERCH (SS313), and the U.S.S. PETO (SS265) with the group
commander embarked in the PICUDA. The PERCH was forced to leave the
attack group shortly after entering the area due to material difficul-
ties. She was replaced by the U.S.S. GUITARRO (SS363).

3. Although considerable damage was inflicted on the
enemy, only one coordinated attack took place by the PICUDA and GUI-
TARRO on 2 June. This attack resulted in the sinking of a freighter
and a tanker, and the damaging of an additional freighter. Later on
the night of June 2-3 the GUITARRO sunk one of two destroyers, ap-
parently sent out on an anti-submarine mission.

4. The coordinated attack group was somewhat handicapped
by enemy air coverage which prohibited the coordination of attack
once contact was established by any one of the attack group. The at-
tack group was also broken up on two occasions when submarines were
detached to search for downed Army aviators.

5. Of note is the fact that the Japanese may be employ-
ing escort carriers for anti-submarine protection to help protect
large convoys.

6. The coordinated attack group is credited with having
inflicted the following damage upon the enemy:

S U N K

By the PICUDA:

1 - Passenger Freighter (class unknown) - 7,000 tons
1 - Freighter (class unknown) - 5,000 tons
1 - Escort Vessel (class unknown) - 1,000 tons

By the GUITARRO:

1 - Tanker (NISSYO MARU class) - 10,500 tons
1 - Destroyer (MINEKAZE class) - 1,200 tons

U.S.S. PICUDA (SS382). Mark 27 Torpedo Attack Number 1. Patrol Number 6.
Time: 0625(H). Date: 28 April 1945. Latitude 34-15 N. Longitude 124-08 E.
Sound conditions: Poor. Depth of water: 250 feet.
Distance to nearest shore or reef: 50 miles. Sea condition: Ø.
Was it raining? No.

TARGET DATA - DAMAGE INFLICTED

Description: Target was presumably a WAKATAKE Class DD or one of three DE's
which were on the side of the five ship convoy from which a
Mark 18 torpedo attack had just been made. For further de-
scription see Torpedo Attack Number 1 of this vessel's sixth
War Patrol Report.
Ship Possibly Damaged: 1 WAKATAKE Class DD, or
1 of three DE's.
Damage Determined by: Thirteen minutes after firing, a rumble was heard
through the hull in the after torpedo room. Imme-
diately following this all three sound gears reported
a loud crackling noise in the direction of the target.
This noise was beating at a rate of 104 times per
minute. This noise, sounding much like one of our
own noise makers, faded out shortly after a pattern
of fourteen (14) depth charges was dropped, 45 min-
utes after firing. These depth charges were almost
simultaneous, they were so close together. Exact
damage inflicted cannot be determined, as no definite
explosion was heard - only this rumble and crackling
noise.

Target draft: 7 feet. Course: 270(t). Speed: 10 kts. Range: Less than 500
yards at firing.
Target turn count: 130 rpm. Target bearing at firing instant: 020(t).
Give any peculiarities noted in target's sound output: None before firing.
