Hardhead

A fish of the croaker family.

(SS-365; dp. 1,526; l. 311'9''; dr. 15'3''; s. 21 k.; cpl. 66;
a. 10 21'' tt, 1 5'', 1 40mm., 1 20mm., 2 .50 cal.; cl.
Balao)

Hardhead (SS-365) was launched by Manitowoc Ship-
building Co., Manitowoc, Wis., 12 December 1943; spon-
sored by Mrs. E. F. McDonald; and commissioned 18 April
1944, Comdr. F. McMaster in command.

Following shakedown training in Lake Michigan the
submarine entered a floating dry dock at Lockport, Ill.,
and was towed to New Orleans, where she arrived 16 May
1944. Hardhead got underway from Algiers, La., 22 May,
and arrived Balboa, Canal Zone, 5 days later. There she
took part in additional training exercises before her ar-
rival at Pearl Harbor 7 July 1944.

Hardhead departed on her first war patrol 27 July and
proceeded to her patrol area off the Philippines. Early
3 August she detected Japanese cruiser Natori east of
San Bernardino Strait, and closed for a surface attack.
The first well directed salvo stopped the cruiser dead in
the water; a second sent her to the bottom. During the
remainder of her first patrol Hardhead rendered lifeguard
services during strikes by fleet aircraft on the Philippines
and operated with a reconnaissance line during the Palau
operation. She arrived Fremantle, Australia, 26 Sep-
tember 1944.

Hardhead's second patrol began as she departed Fre-
mantle 24 October and set course for the Philippines.
While steaming on the surface through the Sulu Sea Oc-
tober she discovered a life raft adrift. In it was Com-
mander (now Rear Admiral) Bakutis, fighter squadron
commander of Enterprise, who had been in the water for
days after being shot down during America's smashing
victory in the Battle for Leyte Gulf. Operating in a co-
ordinated group with Growler and Hake, the submarine
sighted a large cargo ship with escorts 8 November. After
being driven off in one attack, Hardhead aggressively
gained an ahead position and sank Manei Maru. It was
during this attack that Growler was lost. Hardhead per-
formed lifeguard duty off Subic Bay in November and on
the 25th came upon an escorted merchant ship. She sank
a coast defense vessel, damaged the merchantman, and
evaded a retaliatory depth charge attack. Soon after-
ward, the submarine returned to Fremantle, ending an-
other skillful and effective patrol 5 December.

Putting to sea again 24 December, Hardhead began her
third war patrol in the South China Sea. Operating
with Besugo and Blackfin, Hardhead damaged several
ships before sinking Nanshin Maru 2 February 1945. Fol-
lowing lifeguard duty for the B-29 strikes on Singapore
she returned to Fremantle 15 February.

Hardhead's fourth war patrol included a special mine
laying mission. She sailed 20 March 1945 and laid mines
off French Indochina during the night of 2 April. The
submarine then entered the Gulf of Siam, where after
several attacks she sank cargo ship Aruosun Maru 6 April.
Following a visit to Subic Bay to reload 11-15 April, she
patrolled the South China Sea, but found few contacts.
American submarines had by this time reduced Japanese
merchant activity to a trickle. The island nation was
doomed. Hardhead returned to Fremantle 16 May.

Sailing from Fremantle 18 June, Hardhead began her
fifth war patrol, to be conducted in the Java Sea. She
severely damaged a freighter with her deck guns 23 June,
and next day sank four coastal defense craft during an
attack on Ambat Roads with Bullhead. Illness of her
Commanding Officer forced Hardhead to end her fifth
patrol 17 July at Onslow, Australia.

The submarine departed Onslow on her sixth and last
patrol 18 July, and headed back into the Java Sea. She
forced a merchant ship to beach 27 July but found few
targets and returned to Subic Bay 10 August. Soon after-
ward she headed for the Pacific War, in which the submarine had
an aggressive and important part, ended. Hardhead
sailed 31 August and arrived San Francisco via Pearl
Harbor 22 September 1945. She decommissioned 10 May
1946 and entered the reserve fleet at Mare Island.

Hardhead was placed in commission in reserve 8 Febru-
ary 1952 and upon her arrival at New London for conver-
sion was placed out of commission. Following her
"guppy" conversion, including streamlining, installation
of a snorkel breathing apparatus, and larger storage bat-
teries, the submarine recommissioned 24 March 1953. She
joined the Atlantic Fleet for training exercises and tac-
tical drills in the years that followed, operating mainly
in the Caribbean and off the East Coast of the United
States. She sailed for the Mediterranean 7 September
1956 to strengthen the 6th Fleet during the Suez Crisis.

In July 1958 Hardhead joined Submarine Development
Group 2, turning her attention from fleet operations to re-
search and testing of equipment and tactical doctrine.
She operated off the East Coast and in the North Atlantic,
and by 1961 had won four consecutive "E" awards for her
superior performance. Hardhead continued through 1967 to per-
form this vital work in maintaining the technical read-
ity and readiness of the fleet.

Hardhead received six battle stars for World War II
service. All six of her combat patrols were successful.

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

From:

Subject:

1. The first war patrol of HARDHEAD covered a period of 61
days, 34 of which were spent in areas east and southeast of the Philippine
Islands. The patrol was commenced from Pearl Harbor, T.H., and was ter-
minated in Fremantle, W.A. All but the last 12 days of the patrol was spent
in areas under operational control of Commander Submarine Force, Pacific
Fleet.

2. Area coverage was good and most of the patrol was conducted
on the surface. Two days were spent on a plane-guard mission, and there
were no reports or evidence of any downed planes in the vicinity.

3. On 18 August two attacks, one on the surface and one sub-
merged, were made on a target believed to be a battleship. A total of
fifteen torpedoes were fired on these attacks, resulting in eight timed
and observed hits, plus one possible additional hit, as reported by a
bridge lookout. The ship assumed to be the screening vessel, and which
was never visually contacted, took no retaliatory action and interfered
in no way with the attacking submarine. It is regrettable that, in view
of the extreme importance of this target, her immobility after the first
attack, and the absence of any enemy interference, this damaged ship was
not more closely approached in subsequent daylight in order to definitely
and unmistakably establish her identity.

4. HARDHEAD's excellent material condition is reflected in the
absence of material defects during the patrol. The SJ-1 radar will be care-
fully checked and repaired as necessary to minimize the possibility of
further trouble. Upon docking, it was found that several vents and sea
valves require reseating and new gaskets will be required as a result of
more than average corrosion of seats and discs and deterioration of gaskets.
This work is being accomplished. HARDHEAD will be refitted in the normal
period by the Submarine Repair Unit, Navy 137, and Advance Training and
Relief Crew Number Six.

5. The Squadron Commander congratulates the Commanding Officer,
Officers, and Crew of the HARDHEAD for having inflicted extremely important
damage on the enemy.

U.S.S. HARDHEAD (SS365) - Report of First War
Patrol - Comment on.

1. HARDHEAD's First War Patrol was conducted in the
vicinity of SURIGAO STRAIT. It was the first war patrol for the
Commanding Officer, Lieut. Comdr., F. McMASTER, USN., in
command of a Fleet Type Submarine.

2. HARDHEAD fired fifteen torpedoes in two night
surface attacks on a large, fast man-of-war which was identified
by the Commanding Officer as a battleship. The first attack was
made at 0238(ITEM). After this attack a smaller vessel, thought
to be an escort, although it took no offensive action, left the
scene of the attack. The large ship was hit and stopped. While
approaching it after dawn, it was observed to be listed to
starboard with the bow almost awash. At 0713 when about 6000
yards from the target two heavy explosions were heard, followed
by a rumbling noise. The target could not be seen in the
periscope; six minutes had elapsed since the last observation.
Explosions and breaking up noise continued for twenty minutes.
The target sank at Lat. 12°-29'N., Long. 129°-49'E. While
searching the area for wreckage or survivors a chest or drawer
was sighted in the forenoon while submerged, and a large oil
slick after dark on the surface.

3. The Commanding Officer observed the target through
the periscope at a range of about 6,000 yards, and noted the
following distinctive features:

(a) Foremast - large pagoda type, similar to that on
a YAMASHIRO type battleship.

(b) Mainmast - tripod; platform, and stick, similar to
that on a NAGATO type battleship, but located farther aft.

(c) Stack - large high stack near the foremast with
two unidentified shapes aft of it.

(d) Turrets - none observed.

4. On 31 August at Lat. 11°-40'N., Long., 129°-01'E.,
STINGRAY picked up one JAPANESE Officer and three ratings, from
whom the following information was obtained.

(a) They were survivors from the CL NATORI which
received one torpedo at about 0240 (ITEM) on 18 August, 1944.

(b) The ship attempted to proceed eastward after the
attack, but heavy seas caused flooding, and the ship was
abandoned at about 0715. It sank bows first soon thereafter.

(c) The only other vessel present was Transport No. 3,
an armed transport of about 1,000 tons, similar to a Destroyer.
It was undamaged and left the scene soon after the initial attack.

5. The information derived from the POW interrogation
checks so closely with the details of the attack appearing in the
patrol report, that there is little doubt that the ship sunk by
HARDHEAD was the CL NATORI. Except for the number of stacks, all
of the distinctive features noted by the Commanding Officer in
his description of the target apply very closely to this ship.

6. The information in the Narrative and in the Radar
Section of the patrol report, on the subject of Radar Counter-
measures, is of considerable value.

7. The award of the Submarine Combat Insignia is
authorized for this patrol.

8. The Force Commander congratulates HARDHEAD's
Commanding Officer, Officers, and Crew, on inflicting the
following important damage on the enemy:

21 November
0236 Enroute submerged patrol station off Port Natalvi.
SJ contact, 099T, 9,000 yards. Sound heard two sets
of echo ranging. Ceiling in sight but visibility
poor against coast. Decided to avoid. Lat 15-31N
Long 119-36E. Ship contact No. 19.
0310 SJ contact, 109T, 20,000 yards. Believed SJ running
had been faulty on first contact so commenced track-
ing and went ahead flank to gain position ahead.
Target course 170T, speed 10 knots.
0325 Target group difficult to analyze but at 16,000
yards appeared to be one large ship with several
escorts. Sent contact report to HKE.
0350 Target group doubtfully identified as two escort
vessels. On the flanks of several small ships which
are probably landing craft. Decided to attack star-
board screen from a position which would place other
targets on torpedo tracks.
0400 At 5,000 yards sighted starboard screen and it appeared
to be medium sized escort vessel.
0417 Target had zigged at 25° to course 195T presenting
about a 75° starboard angle on the bow. With 30 min-
utes to go before morning twilight headed in for
attack at 15 knots. Then range had closed to about
4000 yards the target zigged back to 170T and the
set-up looked poor. None of the other targets were
in sight because of land in background. Decided to
shoot and at
0427 Fired six torpedoes at a medium sized PC or [UNCLEAR: other], tor-
pedo run 2500 yards, 135° starboard track, 1° div-
ergent spread. All missed. Should not have fired
with set 2 feet and 4 feet. Target
had changed course to the right about the time torpedoes
passed him, turned on a red masthead light and
chased at about 14 knots. Evaded without difficulty.
Could have run ahead of this group and
looked them over after dawn but wanted to be off
Salvador for submerged patrol since it was the only
section of coast nearby where close patrol could be
maintained.
0438 Heard 5 or 6 end of run explosions. Informed HKE
that contact was escort vessels.
0506 Submerged for patrol 6 miles off Salvador Island.
0632 Sighted unidentified plane, elevation 1°, 7 miles.

1948 Weak SJ interference bearing 313T.
2050 Sent BARBHEAD Serial Three reporting Ensign McCUE
     rescued and results to date.

22 November
     Surface patrol west of Manila. Uneventful. Too rough
     for effective submerged patrol off shore.

23 November
0452 Received contact report from LST: Three targets
     bearing 145T, range 20,000 from 14-24N, 119-32E
     on course 240, speed 15 knots.
0700 to Covered courses 230 to 270, speed 15 to 10 without
1100 Contact. Convoy probably headed south for Palawan
     Passage. Could not contact LST after contact report
     was sent.
1213 Set course for Caiman Point to intercept northbound
     convoy.
1531 12 miles off Caiman Point, headed south.
2005 SJ radar contact, one large ship, one small, off
     Hermana Mayor Island bearing 101T, 17,000 yards.
     Target course 010T, speed 12 knots. Decided to inter-
     cept off Mena Point and come around at flank
     speed. Ship contact No. 20. Lat 15-49N Long 119-34E.
2050 Target group off Caiman Point very close to coast.
     Difficult to maintain radar contact.
2111 Contact on second escort about 6,000 yards ahead of
     target. Escorts sighted and took position with first
     escort about 1000 to 1500 yards on port beam, second
     escort about 2000 to 2500 yards ahead.
2136 Hit target bearing 145T, 13,000 yards submerged to
     radar depth about 7,000 yards off Mena Point and headed
     in to close the coast. New moon, very low in west, and
     visibility very poor towards coast.
2150 Doubtful radar range and bearing on target 115T, 6300
     yards. Placed ship at periscope. This placed
     target very near coast on course 020T which headed
     him for Mena Point.
2155 Periscope depth. Could not definitely locate leading
     target. Sound condition to attack very poor.

CONFIDENTIAL

FIRST ENDORSEMENT to
U.S.S. HARDHEAD - Report
of SECOND War Patrol.

From: The Commander Submarine Squadron TWENTY-SIX.
To: The Commander in Chief, United States Fleet.
Via: (1) The Commander Submarines, Seventh Fleet.
(2) The Commander Seventh Fleet.

Subject: U.S.S. HARDHEAD (SS365), Report of War Patrol
Number Two.

1. The Second War Patrol of HARDHEAD, and the first for the
present Commanding Officer as such, covered a period of forty six days,
thirty five of which were spent north of the Malay Barrier. HARDHEAD
was one unit of a coordinated search and attack group, composed of
GROWLER, HAKE, HARDHEAD, with Commander Oakley, Commanding Officer
GROWLER, in command of the Group.

2. Area coverage was good, and in addition to two successful
torpedo attacks, life guard missions were skillfully carried out, two
Naval Aviators from Enterprise being rescued. It is noteworthy that
these two officers, picked up by the same submarine, three weeks and
400 miles apart, were from the same Fighter Squadron.

3. In three torpedo attacks twenty one torpedoes were fired
for a total of five hits, with one possible additional hit.

Torpedo Attack No. 1: In the early morning of 8 November, after
having been skillfully coached to a contact by GROWLER, a submerged
radar and periscope approach was made on a closely escorted large
tanker; four torpedoes were fired at a range of 800 yards for four
hits, resulting in the sinking of this valuable ship. Depth charging
by the escorts was prompt and persistent, but no damage was sustained
by HARDHEAD.

Torpedo Attack No. 2: This attack, on 21 November was a pre-dawn
surface attack on what appeared to be a group of escort vessels. Owing
to darkness and close land background, the identity of the whole group
was never clearly established, but no large vessel was contacted. Six
torpedoes were fired at a medium PC or AK, at a range of 2500 yards,
135° track, and all torpedoes missed. HARDHEAD evaded on the surface,
and no further attack was attempted.

Torpedo Attack No. 3: On the night of 25 November a submerged
night radar - periscope approach was made on a closely escorted AK.
Six torpedoes were fired at the AK, followed immediately by four at
a PC or AK escort, which was hit by one torpedo and blew up. Due
undoubtedly to a fire control error, the torpedoes fired at the AK all
missed. Ten minutes later one torpedo which had been reloaded forward
was fired at the AK, which then presented a 168° track angle. A timed
explosion resulted, checking for a torpedo run of 5200 yards. This is
deemed a possible hit.

Subject:          U.S.S. HARDHEAD (SS365) - Report of Second War
                  Patrol - Comment on.

                  1.      HARDHEAD's Second War Patrol was conducted off
the west coast of LUZON with GROWLER and HAKE in a Coordinated
Search and Attack Group, commanded by GROWLER's Commanding
Officer, Commander T. B. OAKLEY, U.S.N. It was the first war
patrol for Commander F. A. GREENUP, U.S.N., in command of a
Fleet Type Submarine.

                  2.      HARDHEAD made three torpedo attacks which resulted
in one large AO and one escort vessel being sunk, and one large
AK being damaged.

                  3.      Enroute' to the area HARDHEAD intercepted a message
to another submarine directing a search for a downed aviator in
the SULU SEA. Being near the reported position the Commanding
Officer headed for the spot and within two hours after receiving
the message located and picked up Commander F. E. BAKUTIS, U.S.N.,
Commanding Officer of VF-20 attached to U.S.S. ENTERPRISE. Com-
mander BAKUTIS had been adrift on a small life raft for nearly
seven days.

                  4.      HARDHEAD had three two day periods of Lifeguard
duty off SAMAROC POINT. Ensign J. C. CUE, U.S.N.R., also attached
to VF-20 of the ENTERPRISE, was picked up on November 19th. A
most accurate position was given by one of the Fighter Group,
and HARDHEAD was able to effect the rescue expeditiously about
two hours after the plane crashed.

                  5.      The award of the Submarine Combat Insignia is
authorized for this patrol.

                  6.      The Force Commander congratulates HARDHEAD's
Commanding Officer, Officers and Crew on their excellent per-
formance of Lifeguard duties, and on inflicting the following
damage upon the enemy:

         East with scattered low clouds. Passed 8,000
         yards off Nusa Besar.

2112     Ship Contact #1. Sight and radar contact on two
         small and one medium patrol boats stationed just
         North of Southern entrance to Lombok Strait.
         They were evenly spaced across the Strait. The
         largest patrol boat was in a sector of reduced
         visibility in the West. Evaded at 18 knots.

2256 5,000 yards from Bali, squall making up nicely.
     Nearer patrol fired two rounds at range 7,500
     yards. Short 2-3000 yards.

2307 Patrol boat fired three (3) more rounds at range
     5,000 yards just before we entered rain squall.
     Had to head Northwest to clear Bali.

2323 Seven distant depth charges.

2325 2,000 yards off Bali coast. Rain squall cleared,
     full moon. Range had closed to 4,000 yards.
     One round astern ricocheted over bridge,
     Left full rudder and observed splash on starboard
     bow where we would have been so at

2326 Submerged to radar depth 2,000 yards off the
     coast. Paralled target's course hoping he would
     close for a stern tube shot. Target did not
     cooperate so changed course right and closed track
     for a bow tube shot. Went to periscope depth
     when range closed to 2,700 yards and at

2338 Attack #1. Fired two Mk 23 torpedoes from tubes
     #5 and #6, set at 4 feet at a large PC or AM,
     130° port track, range 2,900 yards. Target speed
     16 knots. Used 20 divergent spread and continuous
     periscope bearing. Target changed course 90° to
     the right at about the time torpedoes reached his
     position. Both missed.
     Lat. 8°-20'S Long. 115°-43'E.

2343 Sighted second patrol boat astern of target.

2345 Went deep, rigged for silent running and depth
     charge and evaded on Northeasterly course at
     3-5 knots. Sound reported two more additional
     patrols joined the search party. No depth
     charges were dropped and do not believe they
     ever made contact, probably because of two sharp
     negative layers.

2030 Received instructions from BESUGO to make combined
     attacks from port bow. Took course to change
     position at flank speed. Target group consisted
     of one escort ahead and one well aft on each
     quarter of target.

2100 In position 15,000 yards, 000°T from target about
     7,000 yards off the track using 030°T, as base
     course. TDC bearing 254°T, 4600 yards.
     Commenced approach in training position with
     small port angle on the bow to be in good firing
     position if BESUGO detected and target changed
     course away.

2120 Changed course left to present small silhouette
     to leading escort bearing 155°T, range about
     2500 yards.

2121 Observed two hits on target, one in bow and one
     amidships. Second hit produced flames which
     illuminated vicinity. BESUGO visible at 5,000
     yards without binoculars. Made out details of escort
     ahead. It was a large single stack PC or AM.
     Target which was a large tanker, started sinking
     rapidly by the bow. Ordered shift of targets to
     the escort ahead but the OOD had been blinded by
     the flames since he had been taking continuous
     TBT bearings on the target. Expected fires to
     continue, so at

2122 Submerged to radar depth to continue approach on
     escort.

2123 Only small fire on water visible through periscope.
     Could not make out escort and TDC reported escort
     apparently maneuvering.

2126 Surfaced and changed course for stern tube shot
     at escort. Nothing visible of target except a
     tall column of smoke. BESUGO bearing about 240°T,
     range 5,000 yards. Tracked escort headed our way
     at about 13 knots, range 3,000 yards and closing.
     Angle on the bow 15° starboard. Tracked using
     radar ranges and TBT bearings.

2130 Fired four Mk. 18 torpedoes at escort.
     Torpedo run 2000 yards, 22° starboard track,
     180° gyros. Depth set at 4 feet. Observed one
     torpedo broach and run erratic.
     OOD reported one torpedo track passed close aboard
     the target. All missed. No end of run explosion
     possibly due to shallow water (30 fathoms).
     Lat. 06°-49'N. Long. 102°-58'E. [HANDWRITTEN: Attack #2]
     Not a favorable set-up but gyros were steady at
     180.

2134 Target slowed and five minutes later was tracked
     at speed zero. Perhaps the torpedoes spoiled
     his spirit for the chase. Evaded to Northeast
     in company with BESUGO. No estimate is made of
     tanker tonnage because he was never observed at
     close range with an angle on the bow greater than
     30°.

       angle on the bow since settling on a Southerly
       course and was tracked on base course 155° to
       160°, speed 10-12 knots. At times the base
       course appeared to be 140°T, course 160°T was
       direct route for Singapore.

1030 - Tanker changed base course to about 190°T, and
       increased speed to 13-15 knots, at range of
       about 14,000 yards. Used standard and full

1044 Intercepted distress calls from plane #569
       evidently damaged during strike on Singapore.
       Did not hear any answer to plane calls so
       shifted transmitter to 4475 kcs and gave our
       position with reference to lifeguard reference
       point but plane either did not hear us or was
       suspicious. Authenticated call using CSP 1270
       which is used by 14th Air Force for authentication.
       Positions given by plane were at approximately
       02°-25'N, 105°-22'E and 03°-10'N, 103°-53'E.
       HARDHEAD position 05°-06'N, 103°-50'E. Plane
       position reports changed so radically that he
       may have been in doubt as to his location with
       respect to reference point.

(J) ANTI SUBMARINE MEASURES AND EVASION:
No new counter-measures were encountered. Patrol vessels in Lombok evidently made sight or radar contact on a clear night with full moon at a range of 13-14,000 yards. No difficulty was had in evading submerged at 400 ft. at 3-5 knots under a double negative gradient.
Escort vessels in company with a large tanker off Pulo Rodang appeared completely confused and did not counter-attack after a night surface attack.
Extremely noisy water conditions were encountered in the shallow water of areas Dog Two and Dog Three. Shrimp noises were often heard.

(K) MAJOR DEFECTS AND DAMAGE:
The performance of all equip-ment was satisfactory with the exception of the TBL transmitter as noted under Section (L). Two conning tower improvements not undertaken by the tender during last refit because of the heavy work load are considered necessary. They are: 1. Shift firing panels forward to clear SJ radar units. This job is mainly one of shifting foundations and it is not necessary to alter the cables. 2. Provide 7 MC portable microphones for the TDC operator and for the assistant approach officer.

CONFIDENTIAL U.S.S. HARDHEAD (SS365)

(I) RADIO:

1. RECEPTION:

    (a) Reception was excellent throughout the patrol.
        VIXO Baker frequencies 4370,9250 and 12630 came in
        strong and clear but 16150 was never heard long
        enough for solid copy. Only normal interference was
        encountered on these frequencies.

    (b) Reception on the Wolf Pack frequencies was excellent.
        TBL voice modulated signals were used almost entirely
        with excellent results. The SD antenna was successfully
        used for submerged reception on these frequencies.

    (c) The VHF was not used in the patrol area.

2. TRANSMISSIONS:

Date | Time | Station Worked | No.Grs. | Total Time | Freq.
-----|------||||-------
24 Jan. | 01052 | VIXO | 23 | 16 mins. | 12705
10 Feb. | 02437 | CHN | 50 | 22 mins. | 8470
11 Feb. | 04533 | VIXO | 39 | 26 mins | 8470
13 Feb. | 09053 | VIXO | 42 | 15 min. | 8470

3. CASUALTIES:

    (a) Abnormally high filament, plate and bias voltages
        were observed on the TBL transmitter. This trouble
        was due to a broken pig tail on the speed regulator
        brush (E-422). After the brush was replaced and
        regulator contacts cleaned and adjusted operation was
        normal.

    (b) The TBL high frequency Master Oscillator selector
        switch jumped the track and jammed in between positions
        1&2. This necessitated pulling the transmitter from
        the bulkhead and removing the side of the crystal oven
        in order to clear and re-adjust the switch.

    (c) The motor by pass condenser (C 102-11) in the VHF
        shorted out. This condenser was replaced from spare
        parts and operation was normal.

4. APR-1/SPA:

    The APR-1 was manned at all times on the surface.
    APR-1 contacts are given in detail in section (U).
    APR-1 total operating hours this patrol 932. SPA
    total operating hours this patrol 10. There were no
    APR-1/SPA casualties.

5. IFF:

    The ABK and BN were not used in the patrol area, but
    operated satisfactory on test and South of Onslow, W.A.
    BN total operating hours this patrol 107.
    ABK total operating hours this patrol 99.

U.S.S. HARDHEAD (SS365) - Report of Third War Patrol.

1. The third war patrol of the U.S.S. HARDHEAD was conducted in the
SOUTH CHINA SEA as part of a coordinated attack group consisting of the BESUGO
and HARDHEAD, and for part of the patrol, the U.S.S. BLACKFIN. The Commanding
Officer of the U.S.S. BESUGO was the O.T.C. The patrol lasted fifty-three days,
forty of which were spent north of BALABAC BARRIER.

2. Area coverage was excellent. Five contacts with targets worthy
of torpedo fire were made. Three were developed into attacks. Two, an AO pre-
viously damaged by the BLACKFIN and the BESUGO and on another occasion a DE,
could not be closed for attack because of a change in base course after the
HARDHEAD was submerged.

3. Attack No. 1. In transiting LOMBOK STRAIT heavy patrol boat ac-
tivity forced the HARDHEAD to submerge near the northern entrance. A set-up was
obtained and two torpedoes fired at an AM or PC which had been firing her guns
at the HARDHEAD. Both missed. The target maneuvered either just before torpe-
does reached her or as a result of their passing. At any rate when the patrol
boats formed up for an attack they were unable to regain contact on the HARDHEAD.

Attack No. 2. On 6 January 1945 four torpedoes were fired at
one of three escorts, a PC or AM, of a tanker which the BESUGO had contacted,
tracked, and set on fire. The HARDHEAD was standing by to fire at the tanker
if the BESUGO missed or the tanker started to sink, the HARDHEAD shifted to the escort. The torpedoes missed. One was soon
to run erratic. However, the torpedoes evidently discouraged the escort and
allowed the two submarines to retire unmolested.

Attack No. 3. On night of 2 February 1945 after an hour and
twenty minutes tracking, four torpedoes were fired at a small unidentified AO
or AK. Two hits were obtained and the target sank immediately.

4. Life guard duty was performed on two occasions.

5. The ship was clean and the bearing and appearance of the officers
and crew attest to a high state of morale.

Subject:          U.S.S. HARDHEAD (SS365) - Report of Third War
                  Patrol - Comments on.

1.        The Third War Patrol of the HARDHEAD, under the
command of Commander F. A. GREER, U.S.N., was conducted in the
SOUTH CHINA SEA as a member of a Coordinated Search and Attack
Group consisting of HARDHEAD, BESUGO and BLACKFIN.

2.        The first attack was made on 30 December in LOM-
BOK STRAIT. After being driven down by close gunfire HARDHEAD
attacked the largest of several anti-submarine vessels with two
torpedoes. There were no hits but this torpedo attack apparently
discouraged the enemy patrols because no counter-attacks developed.
On 6 January HARDHEAD joined BESUGO to make an excellently planned
simultaneous attack on a target group consisting of a large, es-
corted AC. As the attack worked out BESUGO sank the AC and HARD-
HEAD pressed home his attack on an escort. Four MK 18 torpedoes
were fired but no hits were observed; and again no counter-attack
was made by the enemy. On 2 February HARDHEAD attacked and sank
a small tanker with two hits out of four torpedoes fired.

3.        This patrol is an interesting study in submarine
group tactics. The several boats were ably directed by Commander
LOGAN in BESUGO, but HARDHEAD and BLACKFIN in return, presented
an excellent example of individual boat cooperation.

4.        The award of the Submarine Combat Insignia is
authorized for this patrol.

5.        The Force Commander congratulates the Commanding
Officer, Officers and Crew of the HARDHEAD on this well conducted
patrol during which the following damage was inflicted upon the
enemy:

## The Story of the "Lost" Submarine USS Harder (SS-257)

The USS Harder (SS-257), a Gato-class submarine, earned a legendary reputation during World War II, becoming one of the most decorated submarines in the U.S. Navy. Commanded by the highly aggressive and successful Commander Samuel Dealey, the Harder was known as "Hit 'em Harder" for its daring tactics and impressive string of sinkings.

**Early Patrols and the Rise of a Legend:**

Commissioned in December 1942, the Harder quickly proved its mettle. Its first four war patrols, all under Dealey's command, were highly successful, sinking numerous Japanese ships, including destroyers, tankers, and cargo vessels. Dealey's strategy often involved attacking Japanese destroyers directly, a risky but effective tactic that earned him the Medal of Honor.

**The Fifth War Patrol and the "Destroyer Killer":**

The Harder's fifth war patrol, from May to July 1944, cemented its legend. During this patrol, the Harder engaged in a series of audacious attacks, sinking five Japanese destroyers in a single week. This incredible feat earned Dealey the nickname "Destroyer Killer" and further solidified the Harder's reputation as a formidable adversary.

**The Sixth War Patrol and the Tragic Loss:**

The Harder departed for its sixth war patrol on August 5, 1944, from Fremantle, Australia, bound for the South China Sea.

(G) AIRCRAFT CONTACTS

Friendly aircraft contacts exceeded enemy aircraft contacts
in the patrol area which included the Java Sea, Gulf of
Siam and area near Great Natuna Island.

Only two enemy aircraft were sighted, one in the Java Sea,
and one south of Pulo Condore.

Procedure while patrolling near MOROTAI and PALAWAN
plane search sectors is to call all plane contacts on
VHF before diving even if possibility exists that plane
is enemy.

TARGET DATA - DAMAGE INFLICTED

Description: The target group consisted of three ships; one
large tanker, one small MFM freighter, and one small
engines aft trawler. The target group was sighted
from the bridge at 14 miles. SJ Radar contact was
gained at 19,600 yards.

Ships Sunk: None

Ships Damaged: One large empty tanker, 10,000 ton (EU), similar to
Rikko Maru, page 283, ONI 208J Revised.

Damage Determined by: One timed hit was heard and observed for-
ward of the bridge. The target settled
by the bow and slowed to 6½ knots.

Target Draft 10 ft Course 250 Speed 9½ kts Range at firing

FIRE CONTROL AND TORPEDO DATA

Six torpedoes were fired in a night surface attack using TBT
bearings and Radar ranges. One and three quarter degrees spread
was used between torpedoes, spreading from aft. forward.
The spread used should have obtained four hits. Further anal-
ysis showed that only one hit could have been obtained. Misses
are attributed to firing of torpedoes when gyros were improperly
matched.
The forward room was ordered to match by hand, when the gyro
match check showed the gyros to be slow in matching. Just before
firing the regulators were shifted back to automatic without
obtaining a good gyro check.

C-O-N-F-I-D-E-N-T-I-A-L

FIRST ENDORSEMENT to
U.S.S. HARDHEAD (SS365)
Report of Fourth War
Patrol.

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

Subject: U.S.S. HARDHEAD (SS365) - Report of Fourth War Patrol.

1. The Fourth War Patrol of the U.S.S. HARDHEAD under the
command of Commander F.A. GREERUP, U.S. Navy, was conducted in the Gulf of
Siam and the South China Sea areas and was of 56 days duration. A special
mission was completed successfully on 2 April 1945.

2. (a) Torpedo Attack Number One was a night radar surface attack
on a large empty tanker, one small M.F.M. freighter, and a small engine-aft
trawler. Six Mark 18-1 torpedoes were fired from the bow tubes at the
tanker, torpedo run 2500 yards on an 80 port track, depth set six feet,
spread of one and one-half degrees between torpedoes. One torpedo hit
forward of the bridge. This spread should have obtained four hits; misses
are accredited to control errors as gyros were not correctly matched.

(b) Torpedo Attack Number Two: Three minutes later two Mark
18-1 torpedoes were fired from stern tubes at M.F.M. freighter, torpedo
run 2,000 yards on a 90 port track, depth set four feet, gyro angle small
with a 2 degree spread between torpedoes. Both missed, reason unknown.

(c) Torpedo Attack Number Three: One hour later three Mark 18-1
torpedoes were fired from the bow tubes at the tanker, torpedo run 2,000
yards, on 55 port track, zero gyro angles, depth set four feet. All missed,
probably due to combination of small spread, only 3 torpedoes fired, and
likely evasion maneuvers of target.

(d) Torpedo Attack Number Four: Three minutes later fired
last two torpedoes from stern tubes at tanker, torpedo run 1,900 yards on
a 95 port track, depth set four feet, spread 2 degrees between torpedoes.
Data indicates these misses should have been hits.

(e) Torpedo Attack Number Five: Forty-five minutes later gained
position ahead of tanker and submerged to radar depth. Fired one Mark 18-1
torpedo from forward tubes using periscope bearings and radar ranges.

ed:

          Installed ST periscope.
          Installed 5" gun and one additional 20 MM mount.
          Installed Mk 7 DRT in conning tower.
          Overhauled two main engines and the auxiliary engine.

     Main motor brushes with welded pigtails, manufactured in Fremantle,
which were installed last refit were found to be defective. They were re-
placed with the original type. (Riveted pigtails).

     Lieutenant (jg) W.H. CHAMBLESS, U.S. Navy was detached. Ensign P.R.
vom EIGEN, DE(G), U.S.N.R. reported. Transferred 15 men to the relief crew

4 Chief Petty Officers).

     Officers and crew returned from their respective rest camps on 30 May and
a normal training period under the supervision of Captain P.H. ROSS, U.S. Navy
was commenced on 31 May. Sound tests revealed a noisy starboard propeller.
Redocking and replacement of the propeller were accomplished during the night
of 1-2 June without interference with the training period. Three exercise
torpedoes were fired. Target services were excellent and special emphasis
was placed on ST periscope approaches, day and night.

FIRST ENDORSEMENT to
U.S.S. HARDHEAD (SS365) -
Report of Fifth War Patrol.

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

Subject: U.S.S. HARDHEAD (SS365) - Report of Fifth War Patrol.

1. The fifth war patrol of the U.S.S. HARDHEAD under the
command of Commander F.A. GREENUP, U.S. Navy, was conducted in the Java Sea
area. Patrol was of thirty eight days duration with nineteen days spent in
the area. Life guard services were performed 1 - 4 July off SURABAYA but no
request for services were received.

2. Torpedo Attack No. 1 was a night submerged ST radar attack
on a three ship convoy consisting of one large Sugar Charlie 1000 tons (EU),
one medium coastal minelayer 800 tons (EU), and one subchaser 100 tons (EC).
Four MK-14 torpedoes were fired from bow tubes at minelayer on 115° starboard
track, torpedo run 1150 yards, small gyro angles, depth set 2 feet. One hit
in bow sank the 800 ton (EU), CMC in 8 minutes.

Torpedo Attack No. 2. Seven minutes later 2 MK 18 torpedoes
were fired from stern tubes at large Sugar Charlie on a 60 port track, 900 yard
torpedo run, depth set 2 feet and small gyro angles. First torpedo broached
and ran erratic and both torpedoes missed as the target maneuvered to avoid.

Torpedo Attack No. 3. Thirty minutes later 3 MK 18 torpedoes
were fired from stern tubes at Sugar Charlie on a 90° starboard track, 1100 yard
torpedo run, small gyro angles, depth set 3 feet using 1° spread between tor-
pedoes. All missed.

3. Gun Attack No. 1. The large Sugar Charlie of the above con-
voy was first attacked by gunfire before the torpedo attack. Four rounds of 5"
were fired at a range of 3100 yards. The fifth round missfired and as the re-
turn fire from escorts was quite accurate the HARDHEAD retired to gain a more
favorable position.

Gun Attack No. 2. After missing the large Sugar Charlie
with five torpedoes in two different torpedo attacks the HARDHEAD surfaced and
twenty minutes later attacked with guns. Of 38 5" rounds fired, 12 were hits
which set the ship afire. Numerous 20MM and 50 Cal. hits were obtained and
target sank two hours later.

Gun Attack No. 3. During the attack on the Sugar Charlie
the escorting subchaser stayed at a safe distance of 5000 yards and didn't
interfere with HARDHEAD's attack. This subchaser was then brought under fire
by HARDHEAD. After a forty-five minute gun battle in which HARDHEAD expended
57 rounds of 5", 1100 rounds 20MM and 800 rounds 50 Cal., obtaining numerous
hits, the target was completely destroyed.

Subject: U.S.S. HARDHEAD (SS365) - Report of Sixth War Patrol.

1. The sixth war patrol of the U.S.S. HARDHEAD began at ONSLOW,
Australia, where Lieutenant Commander J. L. HAINES relieved Commander F. A.
GREENUP, because of the latter's illness. Training was conducted between
ONSLOW and LOMBOK Straits, using other submarines in passage as targets.
The patrol was of twenty-four days duration, of which nineteen days were
spent north of the Barrier.

2. As is not unusual in these latter days of the war, only
three worthwhile contacts were made, and all three were aggressively
attacked. A fourth contact consisting of four motor launches was lost
in the gathering dusk against the shoreline.

3. Gun Attack No. 1 was against a PC-13 class subchaser in
bright moonlight close to the northeast coast of BALI, in the early morning
hours of 23 July 1945. Fire was opened with the 5" gun at 3700 yards, and in
spite of heavy return of fire, probably about 3 inch, the PC was exploded and
sunk by the 15th salvo.

Gun Attack No. 2 was against a good-sized SCL of about 1500 tons.
This was also by moonlight just after midnight on 28 July 1945. The ship
was picked up by SJ radar at 7200 yards, one mile off the northeast coast of
BALI, not far from the attack on the PC five days previous. Fire was
opened at 4300 yards, and the SCL headed for the shore. Some fire was returned
but no splashes seen. The ship beached herself as HARDHEAD closed in with
20MM fire. Twenty-five minutes after commencing to fire, the ship burst
into flames from stem to stern and burned for 24 hours. It was determined
to be totally destroyed by observation the following day.

4. A lugger was contacted on the morning of 4 August 1945. It
was closely screened by a JAKE type plane and could not be attacked with

Subject: Mine Field - Description of.

Reference: (a) Annex "D" to Commander Task Group Seventy-One
Point One Operation Order Number 41-45 (Des-
cription of mine plant).

Point One Operation Order Number 41-45 (Area
and general location of mine plant).

Enclosure: (A) Four copies of overlay of mine plant.
(B) Procedure.

1. In accordance with reference (a) the HARDHEAD (SS365)
laid a field of 23 Mark 12 mines off the FRENCH INDO CHINA Coast,
in the vicinity of PULO OBI, in a rectangle bounded by the follow-
ing points:

(a) 8°-25'-50"N, 105°-03'-15"E
(b) 8°-20'-00"N, 105°-05'-20"E
(c) 8°-18'-10"N, 105°-00'-10"E
(d) 8°-24'-00"N, 104°-58'-05"E

SHIP HANDLING PROCEDURE
TOP SECRET

1. In preparation for the mine plant a tracing was prepared
of the desired area and line which included PULO OBI and ad-
jacent islands. This tracing was drawn to a scale of 1" =
2,000 yards. The tracing was placed on the DRT table, was
oriented by radar fixes, and was used to keep the ship conned
exactly on the line; the ship being conned from the Conning
Tower.

MINE HANDLING PROCEDURE

1. The plant consisted of 23 Mark 12 mines, ten mines were
loaded in the Forward Torpedo Room on the level of tubes 3 and
4, and thirteen mines were loaded in the After Torpedo Room on
the level of tubes 9 and 10. (See sketch #1 for loading
arrangement).

2. In preparation for the plant, mines were rearranged as
outlined in sketches #2 and #3. It was necessary to hoist the
forward mine in #10 reload position in order to pull one mine
from #10 tube.

3. The Torpedo Data Computer was used to space the mines 500
yards. The following set up was used in the TDC:

Target Speed                               0
Continuous Relative Bearing                180°
Initial Range                              1000 yards
Initial Time                               0

The halving device was used to prevent the necessity for
shifting the range dial at 8000 yards. Own ship speed was
maintained at 5 knots on the surface.

Mines were fired from the Conning Tower upon orders from
the TDC operator.

Impulse pressure forward - 190 Psi.
Impulse pressure aft     - 170 Psi.

Loading difficulty aft caused the spacing between the last
two mines to be 590 yards. TDC ranges, computed and actual
firing times, and tube sequence are shown in the following
table:

NARRATIVE
4 August, 1945

Decided to use Mark 27 torpedo because of
air escort.

1230 Had run directly under target and was now ahead
     of him. Rigged for silent running and went to
     170 feet.

1233 Flooded #7 tube.

1234 Equalized pressure through trim manifold.

1235 Opened outer door.

1236 Bearing began moving left and changed course
     left making 2/3 speed.

1242 Bearing steady; slowed to 1/3. JP sound
     reports screws at required noise level.

1243 Fired #7 tube. Target bearing began moving up
     starboard side.

1249 Very mild but definite explosion heard
     throughout the boat. No change in target screws.
     Having never heard a cutie explode assumed
     that ours had not hit or had bounced off.

1318 Periscope depth. Target bearing 063°T, range
     4,400 yards, angle on the bow 170° starboard.
     No damage apparent.

Target screws were heard 18 minutes after
firing on JP and considerably longer on JK.
Target zigged right at about the time of firing
and passed about 250 yds from firing point
3 minutes after firing.
Five and one half minutes after firing a
mild explosion was heard. Target bearing was
048° relative. This was a definite explosion
heard throughout the boat.
Nine minutes after firing a momentary sharp
noise was heard which may have been our own.
The torpedo ran out the tube normally. The
torpedoes screws were never heard on either
