HISTORY OF USS CARP (SS 338)

The keel of the USS CARP was laid 23 December 1943 at the
Victory Yard of the Electric Boat Company, Groton, Connecticut. The
ship was built under the supervision of Captain T.I. YATES, USN,
Supervisor of Shipbuilding at the Electric Boat Company. Launching
took place at 0800 12 November 1944. Mrs. Will Hess, wife of
Representative William E. Hess, of Ohio, christened the ship the USS
CARP. Fitting out also was accomplished at the Victory Yard. Builders
trials commenced 14 February 1945.

The Prospective Commanding Officer, Lieutenant Commander James
Littletop Hunnicutt, USNR, reported for duty with the Supervisor of
Shipbuilding on 21 October 1944. Carl Eugene Harless, Yeoman first
class, was the first of the enlisted personnel to report for duty
as a prospective crew member. By 10 January 1945, all the officers
and crew had reported for duty and on 15 January 1945, a month of
intensive training commenced for all hands at the New construction
training School, U.S. Submarine Base, New London, Connecticut.

The Officers were:

Lt. Comdr. J.L. HUNNICUTT, USNR. Commanding Officer
Lt. Comdr. C.N.G. Hendrix, USN Executive Officer
Lieut. and C.E. OBERBECK, USNR Communications Officer
Lieut. (jg) R.H. SCHOLDAGER, USNR Torpedo and Gunnery Officer
Lieut. (jg) D.A. HORN, USN Engineering Officer
Lieut. (jg) T.A. CORONEL, USN Asst. Communications
                                Officer
Ensign J.S. GROSS, USN Asst. Engineering Officer
Ensign J.G. BINGHAM, USNR Commissary Officer

. 945, the ship got underway for the first training
period at sea and at 1340 made it's first dive with the crew
underway. All went well. Highlights of the training period were the
full power trail run enroute from New London to Newport, Rhode
Island, and contract torpedo firing, of thirty torpedoes, at New Port,
Rhode Island.

The training period was completed without incident. At 1140 on
14 April 1945, Rear Admiral C.W. STYER, USN, Commander Submarines
Atlantic Fleet, called officially on the Commanding Officer, inspected
the ship, wished us a bon-voyage, and at 1640 that afternoon
underway for Panama in company with the USS MORAY (SS-300) and the
USS GILLETTE (DE 681) as escort.

Training was the keynote of the voyage. "DIVE", "DIVE",
"Stations for battle submerged", "stations for battle surface",
"collision drill", and "school of the boat" were the daily routine.
For variety we had "all compartments - Field Day".

-2- USS CARP

On 25 April 1945 the CARP departed company with the USS MORAY
and USS GILLETTE and proceeded independently to a special operating
area. Here we played "hide and seek" with our anti-submarine
planes and blimps. We could be a little cocky - they weren't dropping
depth charges, but the exercise offered good training for both the
submarine and the submarine search group.

On 26 April 1945 with the anti-submarine exercises completed,
we were escorted by PC-1215 to Limon Bay, Colon, Panama. At 0938 we
entered Gatun Lock #1 and commenced the transit of the Canal. We
moored at pier 2, Submarine Operating Base, Balboa, Canal Zone.
Liberty in Balboa was a welcome relief after two such weeks of train-
ing. However, it was liberty until 2200 only, for next day we were
underway again for mere training. This training emphasized torpedo
firing and torpedo recovery at sea.

On 2 May 1945, Lieutenant Commander C.N.G. HENDRIX, USN, Execu-
tive Officer, was injured by a fall on deck of the USS CARP, and was
transferred to the Navy Hospital, Balboa, C.Z. Lieutenant W.L. SMITH,
USNR, relieved Lieutenant Commander C.N.G. HENDRIX, USN, as Executive
Officer.

On 5 May 1945 we got underway from Balboa, Canal Zone for Pearl
Harbor. This trip was made in company with the USS WOODFORD (AKA 86)
USS RUNNER (SS 476) and USS MORAY (SS 300). A large portion of
this trip was devoted to training in approaches for attack on
the WOODFORD, singly, and as a coordinated group. We arrived in
Pearl Harbor on 21 May 1945.

Voyage repairs were made by the USS FULTON; followed by eight
days of intensive training in the Pearl Harbor area. The CARP's
first and only war Patrol was described by her Commanding Officer,
Lieutenant Commander Hunnicutt:

The CARP left Pearl for Saipan on the eighth of June in company
with the USS MORAY. The passage was uneventful except for the
sighting of a torpedo wake near Wake Island. We arrived in Saipan
on June 20, and remained there for seven days while undergoing minor
repairs and taking on stores. We left Saipan on the 27th of June
and arrived at our first lifeguard station at Kii Suido on the second
of July. Here we contacted a Japanese patrol craft and sank same on
the morning of July 3rd. The next day we patrolled submerged around
Shiono Misaki and that night set out to search for a downed aviator.
The search was unsuccessful, and on the morning of July 5 we set
course for Hachijo Shima. From here we proceeded eastward to a
rendezvous with other submarines. We then commenced a sweep toward
the coast of Honshu clearing the road for the carrier strike of July
10 on the Tokyo area.

Our sweep completed, we proceeded northward and commenced a
submerged patrol off Ryori Saki. On July 13th we made two torpedo
attacks on an enemy AM (minesweeper) patrolling off Todo Saki, both
of which were unsuccessful.

— page 5 —
-3- USS CARP

We next proceeded eastward to make another sweep to clear the
path for the task force that bombarded Japan on the eighteenth of
July. Our sweep completed, we proceeded northward to our next patrol
area off Yetorofu Jima. We conducted our first battle surface against
six Japanese Sea Trucks, of which we sank two and damaged four with
our 5" and 40 MM guns, in a running gun battle which lasted about an
hour. We were prevented from finishing off the Sea Trucks by Japanese
aircraft which dropped two depth bombs fairly close aboard. The sea
trucks were wooden ships of about 500 tons each.

We next proceeded to Eruan Misaki in the sea of Okhotsk where we
contacted several Russian ships; from there to Shiretoko Misaki and
then back to Yetorofu Jima.

Early in the morning of the 26th of July we contacted several
targets in a dense fog, and commenced attack. We sank the largest of
the group, estimated to be a 4,000 ton ship with one torpedo hit of a
two torpedo salvo fired at close range. We decided to remain on the
surface and close in and shoot at very close range at the second
target. At 500 yards range we sighted the target which opened fire
with what appeared to be 40MM guns and machine guns. Our ship sustained
only a few hits from machine guns and these caused no appreciable
damage. We fired one torpedo which hit the target amidships resulting
in a terrific explosion. The target was estimated to be a 1,200 ton
escort of the CM (Minelayer) class. After seeing the torpedo hit we
submerged and upon surfacing some twenty minutes later, saw a survivor
in the water. We circled in an attempt to recover the survivor, but
lost sight of him in the fog and were unable to locate him again.

On succeeding days we patrolled off the southeast coast of
Yetorofu Jima. A heavy fog usually prevailed with resultant low
visibility. We entered the harbor of Hotohappu Wan in a heavy fog,
but could locate no targets.

On July 30 in a heavy fog, we contacted what appeared to be a
single target and made an unsuccessful torpedo attack on it before
discovering that the contact actually consisted of four 100 ton
luggers very close together. We closed in at high speed on the sur-
face and opened fire at about 400 yards. We sank two of these luggers
with our 40 MMs and .50 cal. and left a third burning.

As the fog lifted the OOD sighted a beached AK of about 3,000
tons with several small luggers nearby. We were being fired at from
what appeared to be a shore battery, so submerged and headed for the
target. The visibility decreased again, however, so we turned away to
wait for more favorable conditions. The next morning the fog lifted;
we surfaced and headed for the target again and this time fired three
torpedoes from our bow tubes, all of which hit, demolishing the target.
We had come in to less than 70 feet of water to fire our torpedoes and
it was at this depth that we were detected by a lugger which was acting
as a picket for the AK. The lugger dropped two depth charges on us
but they did no damage. As the depth of the water increased we eased
down to 70 feet and headed for deep water.

— page 6 —
-4- USS CARP

A look around a few minutes later showed three luggers astern,
chasing us. Numerous explosions were heard, some of which were depth
charges being dropped by the picket boats, and some of which appeared
to be shells hitting the water, probably from a shore battery. A
heavy fog closed in; so we surfaced and proceeded to Yetorofu Kaikyo.

The next day, August 1, we contacted a whale killer vessel,
trying to get a harpooned whale alongside. We fired three torpedoes
at this target, but the whales speeded up just after firing and all
three torpedoes missed. We had insufficient ammunition to make a
battle surface Woth while and as the target turned away and headed for
shallow water, we were unable to get another shot with our torpedoes.

That afternoon we set our course for Midway and arrived at Mid-
way the 7th of August. A two week recuperation period was given the
officers and crew; while our boat was being refitted by the USS
GRIFFIN and the relief crew of Sub Div 121. This was followed by
long interminable days of waiting for orders, for war with Japan had
officially ended. We departed Midway on 1 September 1945 in company
with the USS HOE, and arrived in Pearl Harbor on 5 September 1945.
After a 10 day stay in Pearl Harbor, we departed for Seattle, where
we arrived on 22 September 1945.

The CARP'S first and only war patrol was a successful one.
Officers reviewing the patrol made the following comments: "The
patrol was characterized by aggressiveness and veracity of purpose."
"This Patrol is noteworthy for the excellent area coverage and
persistent search whichresulted in many contacts."

By Directive dated March 1946, USS CARP (SS 338) has remained
in active duty status, attached to the U.S. Pacific Fleet.

            beach that radar could not pick them up.

            Second target was identified as a CM (EU); sank: Lat. 45°-11'-28"N

0650 (I) Both radars back in commission, but no contacts.

1200 (I): Lat. 45-21 N, Long. 149-05 E.

29 July 1945

0437 (I) Ship sighted from bridge, bearing 310° T, range about 15,000 yds.
Target appeared to be a whale killer. No target on radar. Turned
away to track, but target headed into Hitokappu Wan. (Ship
contact No. 13).

0447 (I) Fog closing in, headed for target.

0528 (I) Submerged, hoping target would come back out of harbor.

0635 (I) Sighted smoke in harbor on same bearing that target was last seen.

0843 (I) Sighted small fishing boat bearing 302° T, range about 5,000 yds.

1124 (I) Fog closed in leaving visibility only a few hundred yds. Surfaced
in Hitokappu Wan for a radar search of the harbor. Only one small
pip on radar. Closed target to 1,000 yds. before it came into
sight. Target identified as a Sampan, possibly a picket boat.
(Ship contact No. 14).

1210 (I) Visibility improving, left the harbor and commenced surface patrol
about 3 miles off harbor entrance.

1200 (I): Lat. 44-51 N, Long. 147-44 E.

30 July 1945 (Cont'd)

1032 (I) Radar reported that contact now appeared to be four small targets
           very close together.

1037 (I) Manned 40MM's and 50 cal. guns and headed for target group.

1044 (I) Targets sighted at range of 300 yds. and identified as 4 luggers
           (100 ton, E.C.) targets commenced firing 30 cal. machine guns.

1045 (I) Opened fire with 40MM's and 50 cal. guns. At this range,
           practically all of our shots were hits.

1046 (I) One target burning badly.

1048 (I) Secured firing as targets went out of sight in the fog. Believe
           two of these targets were completely destroyed, with a third one
           also left burning. Hits were obtained on the fourth, but he was
           still firing his 30 cal. machine gun when we left him.

1118 (I) As fog lifted, OOD sighted ship with bow up on beach at
           Lat. 45°-11'-12" N, Long. 148°-14'-45" E. (Ship contact No. 16),
           range 6,000 yds. OOD reported gunfire which he believed was
           coming from a shore battery. Turned away to look target over.
           Sighted several luggers near him, which were probably unloading
           his cargo. We had wasted one torpedo firing at the four luggers,
           but they had led us to this more worthwhile target.

1123 (I) Submerged and headed for target.

1157 (I) A total of 6 luggers are now in sight.

1254 (I) Visibility closed in to about 1500 yds., so turned away to wait
           for more favorable conditions for attack.

2008 (I) Surfaced, patrolling back and forth, standing watch over our new
           prey.

1200 (I): Lat. 45-10 N, Long. 148-17 E.

31 July 1945

1027 (I) Fog lifting, beached AK in sight, submerged and headed for target.
           The target's bow appeared to have been broken where it hit the
           beach.

1101-33 (I) Fired 3 torpedoes from bow tubes, with 000° gyro, 2,300 yards,
           range, 155 starboard track, depth set 4 ft. Commenced swinging
           left, running at 58 ft., with 2 fathoms of water under the keel.
           The water was calm and I could see the surface turbulence of
           these Mark Eighteens. The Japs on the AK could also see them, as
           many of them rushed to the rails and started pointing, and then
           began firing at the torpedoes with machine guns. (Attack No. 6).

31 July 1945 (Cont'd)

1104-12 (I) First torpedo hit amidships, sending a column of water over a
            hundred feet in the air.
1104-48 (I) Second torpedo hit, with a terrific explosion.
1105-30 (I) Third torpedo hit. The ship was a complete wreck.
1108 (I) Took a sweep around to check on screws reported by sound. One
            Lugger had closed in on our beam. He was headed for us and only
            about 300 yds. away. This lugger had previously been observed
            patrolling back and forth about 4,000 yds. from the AK, apparently
            acting as a picket. Lowered the scope and ran at full speed.
1110 (I) Two depth charges dropped by the lugger.
1112 (I) We now have 3 fathoms under the keel; so eased down to 70 feet and
            continued out for deep water. Heard numerous explosions, some
            identified as depth charges and some as gunfire, probably from
            shore batteries.
1116 (I) Took a look around. Sighted 3 Luggers astern, chasing us.
            (See special report).
1240 (I) Visibility about 200 yds; surfaced. Headed for Yetorofu Kaikyo.
1823 (I) Sighted smoke bearing 048° T.
1848 (I) Sighted ship bearing 048° T, range about 18,000 yds. (Ship contact
            No. 17).
1904 (I) Lost contact, target apparently went in close to shore, possibly
            to anchor.
1200 (I): Lat. 45-11 N. Long. 148-23 E.

1 August 1945

0620 (I) Sighted ship bearing 048° T, range about 20,000 yds., commenced
            tracking. This is apparently the same ship that we sighted at
            1848, 31 July. Target is patrolling back and forth.
0700 (I) Submerged and headed for target. Identified target as a whale
            killer.
0900 (I) Target has line out from bow to marker buoy with a flag marker.
            Believe target has harpooned a whale and is trying to get it
            alongside.
0914 (I) Commenced firing three torpedoes from bow tubes with a 005° gyro,
            124 port track, 1350 yard torpedo run. Target speeded up just
            after firing and all torpedoes missed. (Attack No. 7).

0920 (I) Target started dropping depth charges, and reversed course.
           Started coming right to get another shot, but target turned
           away and headed for shallow water. We have only 3 rounds of 5"
           so don't think it worth while to battle surface. Target is close
           enough to beach for protection of shore batteries.

1249 (I) Surfaced and headed through Itorofu KaiKyo.

Description: Target is believed to have been a medium freighter, judging from
turn count, number of escorts, and range at which target was
contacted by radar. Target was contacted by SV radar at 22,550
yds, in company with three other smaller vessels, probably
escorts.

Ship sunk: One unidentified ship. Lat. 45-10-23"N. Long. 148-26-24 E.

Damage determined by: Explosion of torpedo was heard after period of time
corresponding to torpedo run. Targets screws were
heard to stop, and target's pip on PPI scope was
seen to split in two and then disappear.

U.S.S. CARP (SS338) GUN ATTACK NO 1 PATROL NO. 1

Time: 1637 LZT Date: 7-18-45 Lat. 44-24-30 N, Long. 146-58-54 E

Target: 6 Wooden Sea Trucks.
TARGET DATA - DAMAGE INFLICTED

Sunk: Two Sea Trucks, of approximately 500 ton each. (E.C.).
     First: Lat. 44-24-30 N, Long. 146-58-54 E.
     Second: 44-25-32 N, Long. 146-57-54 E.

Damaged: Four Sea trucks of 500 tons each. (E.C.).

Damage determined by: Two of a group of six sea trucks were seen sinking as
                     result of gunfire. The other four were smoking heavily
                     at time submarine was forced to submerge because of
                     enemy aircraft attack.

Details of Action

One 5"/25 and two 40MM guns were used, both firing high capacity ammun-
ition. 108 rounds of 5"/25 high capacity ammunition and 498 rounds
of H.E.I.T. 40MM ammunition were expended. Average range was 3,000
yards, diminishing effectiveness of 40MM fire, many rounds having
exploded prior to reaching targets. TDC was used as rangekeeper
for 5"/25, range and deflection spotting being done by periscope.
Lag in incorporation of range spots to TDC generated ranges resulted
in excessive range dispersion of 5" projectiles.

Target Data - Damage Inflicted

Target: Four Wooden Luggers.

Sunk: One 100 Ton Lugger. (E.C.).

Probably Sunk: Two 100 ton Luggers. (E.C.).

Damaged: One 100 ton Lugger. (E.C.).

Damage determined by: Ships sunk were caught by cross fire of two 40MM and
two 50 caliber machine guns, disintegrating under
concentrated fire that lasted about forty seconds.
Ship damaged was smoking heavily as a result of
incendiary 40MM and 50 caliber projectiles.

Details of Action

Two 40MM and two 50 caliber machine guns were weapons used, firing
at a mean range of 500 yds. Heavy fog and short range made use of 40MM
panoramic sights impractical. All guns performed satisfactorily, but
the 40MM chutes gave some trouble, empty cases having a tendency to pile
up in the chute. It is recommended that chutes be shortened, made of
corrosion resisting metal, and that their diameter be enlarged, to
prevent a recurrence of this.

170 rounds of H.E.I.T. 40MM ammunition and 550 rounds of 50 caliber
ammunition (A.P.T. and I equally divided) were expended.

ANTI-SUBMARINE MEASURES AND ANTI-SUBMARINE TACTICS

One anti-submarine search plane was sighted off Shiono Misaki.
A few hours later two anti-submarine vessels appeared. The plane
was on the surface by a KO. After submerging the KO passed only
hundred yds. from a [UNCLEAR: ship] but did not sink or drop any depth charges.
Three other vessels later swept through the area dropping depth
charges at random.

Three anti-submarine vessels were encountered off Todo Saki.
were closed in and KO to 2,000 yds. in a surface attack. Both
were pinging but would not ever have known they were being attacked
had it not been for our torpedoes, remaining in the rough sea.
They dropped depth charges over for hours at random.

We were bombed once by an anti-submarine patrol plane off
Moturofu Jima.

Following attack on a grounded ship off Moturofu Jima,
were depth charged by two ones being used as picket boats.

Following attack on a whale killer, the two dropped twelve

U.S.S. CARE (SS336) Report of First War Patrol
(K) MAJOR DEFECTS AND DRUGS: (Cont'd)

Bathythermograph

The bathythermograph has failed to register properly
since the first week of the patrol. The temperature input lags
the pressure input so that the trace is almost rectangular.

Periscope Hydraulic Packing

The hydraulic packing on number 2 periscope lifting rods
began leaking about the middle of the patrol. It is believed that
the ring of neoprene grommet type packing is insufficient to
withstand the constant use required.

Ordnance and Gunnery

A minor explosion occurred in M.K. 18-2 (Converted)
torpedo serial No. 57638 when tube containing torpedo was flooded.
This was traced to a faulty gasket in tail charging lead. Four
cells were damaged, but torpedo was put back in commission with
not reduction in speed.

Crosswires of pointer's telescope on 5"/25 rotated during
firing. While this does not change position of intersection of
crosswires, it increases difficulty in getting on target.

Momentary stoppages were encountered in 40M guns due to
empty cases piling up in chutes. It is believed that shortening
and widening chute would have obviated this.

TBT flooded out through rubber gasket on switch box.

Present number of spare transformers furnished for TBT
switch box is insufficient.

It was found that .012" chrome plating on MK 1 signal
projector eliminated corrosion that has been causing trouble
on nonplated and cadmium plated projectors.

(L) Radio

The operation of all radio units was satisfactory, with
no major casualties.

SV Radar

The reliable performance of this unit can only be given the
highest praise. The ship has a confidence in the performance of the
SV which was never given any SD or SJ. Typical of the ranges which
this unit has given are:

     Maui, T.H.: 120 Miles (10,000 ft. Mountain).
     Molokai, T.H.: 70 Miles (4,600 ft. Mountain).
     Retorofu Jima, Kuriles: 105 miles.
     Aircraft Carrier: 75,000 yds.
     Decoy Balloon: 10,000 yds.
     Aircraft: 60 miles (Phenomenon).
     Submarine: 20,000 yds. (Reliable).
     B-29: 30,000 yds. (Reliable).
     Convoy: 3 Russian ships; 45 miles (Phenomenon).
     AK, traveling close to beach: 23,000 yds.
     Birds: 4,750 yds.
     Destroyer: 37,000 yds.

As a consequence of this reliable performance, the SV has become
our general search radar i.e. both air and surface search. The SJ
has acquired a secondary role; as search radar when the SV is
serviced; for communications with friendly submarines; for fire
control bearings; for range spottings in gun actions.

The greatest handicap of the SV at present is its lack of
accurate bearing information. While it is realized that this
has not designed for fire control, its superiority as a surface
search radar as compared with the SJ makes some means of obtaining
accurate bearings highly desirable, it is felt that some development
along this line is indicated.

The installation of the VJ-2 in the conning tower served as an
invaluable accessory to the SV for the determination of fire control
bearings, accurate to within one degree. The VJ-2, installed at the
Submarine Base, New London, Connecticut, as an experiment by most radar
personnel, has proved highly satisfactory. The ship now considers it virtually a PPI
picture for interpretation in the conning tower which the best
operator's report from the control room cannot describe.

Casualties are not nearly as frequent as they are with the SJ.
The greatest source of trouble seems to be in the failure of the
5D21's. The possibility of losing four of these simultaneously
in case one fails makes it desirable to have at least 16 spares on
board instead of the 8 allowed for the SV.

          In operating near land, it was observed that when #1 periscope
          was raised, a reflection having the appearance of a rain squall is
          obtained at relative bearing 000 and at the same range as land.

          On July 31, 1945 the maintenance log showed:

               1484 hours operation since installation.
               576 hours of operation in July.
               10 hours out of operation in July.

          The modulation network now in service has 850 hours of operation.
          The network originally installed failed after 700 hours; predicted
          life was 800 hours. The spare network on board will be installed
          before going on the next patrol and it is hoped that a spare will be
          obtained during the refit.

          One spare magnetron on board was useless, apparently because it
          failed to line up properly with waveguide.

          The performance of the SJ radar was generally satisfactory.
          There were the usual number of minor casualties, none of which caused
          the equipment to be out of commission very long. One persistent
          trouble has plagued us since installation: Erratic gain. The grass
          jumps noticeably. The trouble has defied the persistent effort of
          ship's personnel as well as those of the radar repair forces at
          Panama and at Pearl Harbor. It is believed that the IF or AFC
          may be the source of this trouble. If the trouble cannot be
          remedied in the units now on board during the coming refit, it is
          requested that a new transmitter or new range indicator or both
          be furnished.

ST Radar
          Performance satisfactory.

          Typical ranges obtained:

               Land (Submerged): 30,000 yds.
               Land (Surfaced): 70,000 yds.
               Whale Killer: 5,000 yds.
               AM: 6,500 yds.

SONAR GEAR AND SOUND CONDITIONS

(N)
CA-2
The JK-QC and NA gave satisfactory performance throughout the
patrol. The QB, which has been modified with gold braid slip
rings for continuous training and for input to a TDM unit, was far
from satisfactory. The slip rings are a constant source of trouble
and require the finest adjustment for reliable reception. From time
to time there is a loose connection within the head itself and this
will be investigated during the coming refit.

JP-2
Performance satisfactory. The sum and difference listening
attachment and the 5 foot head combine to make JP bearings reliably
accurate. The JP is considered superior to the JK or QB for long
ranges and accuracy of bearing. One picket boat was picked up at
about 400 yds. while we were making standard speed (6 kts).

TDM
The operation of the TDM is described in a special report because of
the great number of casualties experienced. It was out of commission
so often and required so much maintenance that the ship had little
confidence in it as detection gear. However on occasion the TDM
operated very well and it is hoped that this unit will be repaired
during the coming refit, so as to give reliable performance on the
next patrol.

RADIO COUNTERMEASURES

Only slight interference, due to enemy signals, was encountered
throughout the period on all sub-fox frequencies except 9050 KC's.
Heavy interference was encountered at all times on 9050 KC's.
NPM's signal failed frequently as if caused by a faulty transmitter.

Slight jamming of the CW type on 9050 and 13655 KC's was
encountered off Honshu during period of July 5 to July 15. This
type of jamming is easy to combat.

Both reception and transmission were very good during the
patrol.

SONAR COUNTERMEASURES

On one occasion two A/S vessels in company were pinging
simultaneously, one on 14.7 kc. and the other on 17.5 kc.

REMARKS

(V)
A range step delay unit was manufactured by Lt. (jg) Plummer,
as a portable unit for use with the SJ or SV for increasing
the range stop 40,000 yds. This made it possible to read
radar ranges accurately out to 84,000 yds., and was found very
useful.

It was necessary to renew two cracked main engine cylinder
liners during this patrol. This makes a total of five liners
renewed since commissioning 28 February 1945, and is considered
excessive for engines that should be reliable.

Subject: U.S.S. CARP (SS338) - Report of War Patrol Number One.

1. The first war patrol of the U.S.S. CARP (SS338) under the
command of Lieutenant Commander J.L. HULLICUTT, USNR was conducted along the
East Coast of Honshu and in the Kurile Islands. Thirty-two days were spent
in the patrol area.

2. The patrol area was covered in an aggressive and thorough manner
and yielded numerous small ship contacts. Every effort was made to investigate,
close and attack each contact.

3. On 13 July two Mark 18-2 torpedoes were fired from a good firing
position at an AK in a radar surface attack but both torpedoes missed. A
submerged approach was made on the same AK and one Mark 18-2
torpedo was fired, depth set 3 feet, in a force 5 sea. This torpedo prematured
about 400 yards short of the target.

On 26 July an unidentified medium freighter was sunk by one Mark
18-2 salvo in a surface radar approach in a dense fog. Target
was never sighted although torpedo run was 580 yards. A half hour later a
small AK in company with the previous target was sunk by one Mark 18-2
hit, torpedo run 360 yards, while CARP was under gun fire from the AK. Tonnage
of the AK was estimated at 1200 tons.

On 30 July in a dense fog one Mark 18-2 torpedo was fired at
what appeared to be one target but later was identified as four 100 ton luggers.
Two of these luggers were sunk, two probably sunk and damaged in a well conducted gun
shoot. Visibility improved following the gun action and a beached AK, apparently
undamaged except for a damaged bow, was sighted. A submerged approach was con-
ducted the following day and three Mark 18-2 hits demolished the target.

On 1 August three Mark 18-2 torpedoes fired in a submerged approach
at a whale-killer type target, missed due to target increasing speed just after
torpedoes were fired.

Two 500 ton wooden sea trucks were sunk and four damaged on 18
July in a smartly executed gun action. Destruction of the damaged sea trucks
was prevented by the sudden appearance of a plane which bombed CARP after she
had submerged.

4. The CARP arrived from patrol in an excellent condition of clean-
liness and material. Morale is naturally high. It is expected that refit will
be completed in the normal time.

1.
The first war patrol of the CARP, under the command of Lieutenant
Commander J. L. Hunnicutt, U.S. Navy, was conducted off the Honshu Coast and in
the vicinity of the Kurile Islands.

2.
The first half of this patrol was devoted mainly to lifeguard
services off the Honshu Coast. During this time the CARP was a member of a
coordinated submarine group which conducted surface sweeps for picket boats in
advance of the Third Fleet's approach to the Honshu Coast. No opportunities
occurred to rescue aviators. This patrol is noteworthy for the excellent and
persistent search which resulted in many contacts. Practically all
of these contacts were small craft. The CARP availed herself of every opportunity
to strike the enemy; and in one case she penetrated shallow waters to completely
destroy a stranded cargo ship.

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

4.
The Commander Submarine Force, Pacific Fleet, congratulates the
commanding officer, officers, and crew of the CARP for this aggressive, well
mined, well conducted and profitable patrol. The CARP is credited with having
