Springer (SS-414) was laid down on 3 October 1943
at Vallejo, Calif., by the Mare Island Navy Yard;
launched on 3 August 1944; sponsored by Mrs. M. S.
Tisdale; and commissioned on 18 October 1944, Comdr.
Russell Kefauver in command.
Springer sailed for San Diego on 3 December to con-
duct sea trials and shakedown training. After availa-
bility, she departed Mare Island for Hawaii on 8 Janu-
ary 1945 and arrived at Pearl Harbor the following
week. On 4 February, she steamed to Guam; topped off
her stores and oil; and, on the 17th, sailed for the
Ryukyus to begin her first war patrol.
Springer rode out several heavy storms and was
driven down many times by enemy aircraft, but
she finally spotted two Japanese warships on 11
March. The ships were at a range of 22,000 yards,
steaming at 17 knots, so the submarine surfaced to
give chase. She was forced to submerge immediately
by planes, and the pursuit was abandoned. Later in the
month, the submarine made radar contact with three
ships, and she tracked the largest for three hours.
When it was within torpedo range, she made a surface
attack with four torpedoes. She scored two hits and
the target began to burn. An hour later, Transport No.
18 was still afloat so she sank it with another torpedo.
The submarine returned to Guam on 25 March and
was refitted by Proteus (AS-19).
Springer, Trepang (SS-412), and Raton (SS-270)
sailed on 20 April for the Yellow Sea where they were
to operate as a wolfpack. Eight days later, the pack
checked Tomei Harbor on Fukue Shima. At 0515,
Springer sighted two ships hugging the coastline, but
she found it impossible to close nearer than 6,500
yards. She heard 14 explosions at approximately 0630,
and was being depth charged by the victim's escort.
Springer headed out of the harbor, and sighted the escort returning
alone. At 0830, the submarine fired three torpedoes.
The target went dead in the water. An hour later,
was abandoning ship, Springer fired another torpedo.
It hit under the target's No. 1 turret and blew off her
bow. Two planes and two patrol craft approached, so
SS-414 went deep and cleared the area, leaving
Japan's Submarine Chaser No. 17 to sink.
Springer and Trepang contacted three targets on 30
April. The morning was very foggy, and the subma-
rines decided to make a surface attack. Just as Sprin-
ger reached a favorable firing position around noon,
the fog suddenly lifted and left her exposed to a
destroyer escort crossing her stern with guns firing. Springer
submerged, went deep, and rigged for silent running.
Soon the first of 27 depth charges came down, and all
were uncomfortably close. Speakers were knocked off
the bulkhead, bulos were smashed, and valves were
lifted off their seats. When all was quiet, the subma-
rine surfaced for a look as the fog closed in again.
One more explosion was heard as Trepang sank the
cargo ship Miho Maru.
On the night of 2 May, Springer attacked a ship
and two small escorts with a spread of four torpedoes.
She heard the first explode and saw and heard
two more hits which blew up and sank the frigate
Ojika. The next night, she fired a spread of torpedoes
at a ship making an antisubmarine sweep and sank
the Japanese Coast Defense Vessel No. 25. On 4 May,
American pilots were sighted but, on 14 May, after
watching a dogfight between a Japanese fighter and
four of our carrier planes, she fished the dead enemy
pilot from the water. After removing his papers, the
submarine's commanding officer returned his body to
the sea. The submarine concluded her patrol at Guam,
on 18 May, and was refitted by Proteus.
Springer sailed to Saipan on 16 June and began her
third war patrol the next day. This was a combination
offensive and life guard patrol in the Tokyo Bay area.
On 26 June, she rescued eight men from a downed
B-29 and transferred them to Tigrone (SS-419).
Springer and Trepang were notified that there was
another crew down about 50 miles distant. They raced
to the scene and Springer rescued one airman while
Trepang picked up several days later. After an
uneventful patrol in Suido from 17 to 23 July, the
submarine sailed for Guam.
Springer was at Guam when hostilities with Japan
ceased. She departed there on 17 August and headed
for the west coast of the United States. She arrived at
Mare Island on 5 September 1945 and shortly thereaf-
ter was attached to Mare Island Group, Pacific Reserve
Fleet. In January 1947, her status was changed to in
reserve, out of commission.
In April 1960, Springer was moved from Mare
Island to the San Francisco Naval Shipyard to be
modernized in preparation for her transfer to the
Republic of Chile. She was recommissioned on 24 Sep-
tember and the overhaul was completed on 15 November.
From 19 December 1960 to 19 January 1961, she held
alongside and underway training for the Chilean crew.
Springer was decommissioned on 23 January 1961
transferred to the Republic of Chile and commissioned
in the Chilean Navy as SS Thome on that date. Her
name was struck from the Navy list on 1 September
1972, and her hulk was sold to the government of
Chile as scrap.

(A) PROLOGUE [HANDWRITTEN: (1 of 4)]

SPRINGER was commissioned at Navy Yard, Mare Island on October
18, 1944. She was completed and accepted on November 29, 1944. Reported
to ComSubRon One, and ComSubsFac for duty on that day. Following a
three day loading period departed for San Diego on December 3, 1944.
Operated at San Diego under ComSubRon Forty-Five until December 21, 1944.
During the operating period at San Diego conducted training exer-
cises, contract builders trials and rendered services to the San Diego
Sound School.
The surface vessels with whom SPRINGER operated at the Sound School
were in their early stages of training and could not maintain contact
when SPRINGER used evasive action or submerged below a density layer.
The four days devoted to the Sound School would have been used to advan-
tage for training and the type target service the SPRINGER furnished
could have been rendered as effectively by a Sugar type boat. In view
of the above and the fact that Mare Island Boats have only 14 to 18
operating days before proceeding to Pearl, it is recommended that New
Construction from Mare Island be exempted from furnishing target services
at San Diego.
Arrive at Mare Island on December 23rd for post shakedown repairs
and departed for Pearl Harbor on January 8, 1945. Arrived at Pearl
Harbor on January 15, 1945. Remained in Pearl a period of 19 days of
which 13 days were devoted to training under Commander S. S. BENSON, USN.
The spirit and interest shown by the personnel of the Submarine
Base, Pearl Harbor was sincerely appreciated by all hands aboard SPRINGER.
All work was well done and accomplished with dispatch.

1430 Identified targets as four small patrol craft in formation line
     of bearing 090° relative, distance about one thousand yards,
     speed between three and five knots. Apparently making an AS
     sweep. Posit: 26-07 N 125-14 E.
1515 Formation changed from a northerly to an easterly course.
2020 Surfaced.
2300 Finally got off weather message to CSPAd.
2305 Set course for position to cover approaches to NAHA.

March 1.
0800 Hear voice transmissions of our zoomers over OKINAWA JIMA. We
     are north of the approaches of NAHA HARBOR. Decided that the Japs
     aircraft would be very busy during the strike so remained on the
     surface to increase our chances of seeing any Jap shipping which
     might come out. Tuned in on the lifeguard frequency in case we
     might have a chance to render aid. We also have been picking up
     radar on 152 mcs. all morning.

1310 Sighted plane (FRANCES) - Dove as he was close aboard. This
     was 5th time we have sighted aircraft close aboard and made dives
     yet we have yet to be bombed. Visibility has been poor on all
     one occasion but still I feel we have been sighted at least
     once. It is possible that they want us to believe that we are
     undetected so they can reroute their convoys.
1915 Surfaced.

1900 Surfaced.
2355 Radar contact with threo ships 342° T range 22,000 yards.

March 18.
0000 Started tracking the rear target which was on a southerly coursc
and closing the range and giving evidenco of 10 cms radar at
intervals on the SJ. Original plot and track showed all three
targets making about 15 knots. Continued to track this target
on a base coursc, speed 11, which headed for AGUNI SHIMA until at
0027 A check on the other two targets revealed that they were on a
westerly coursc and the range was opening. It looked as if we
had been picked up and were being eased away from what appeared
to be the main targets. Came to west to work our way around and
regain contact with the other two.
A sweep to the west and north revealed nothing. At this point
it looked as if we were out of luck so headed back for AGUNI
assuming that the ships would join up in the vicinity of the pass
west of AGUNI.
0215 Picked up our first target again bearing 142° T, range 20,000.
Plot and TDC showed he had maintained base coursc and speed
since we left him to sweep to the west.
Decided it was time SPRINGHAM sunk a ship, radar or no radar,
so commenced working into firing position and at
0303 Fired four bow tubes across sea, depth six feet at torpedo run
of 2200 yards.
Observed and saw two hits. Target started firing from a
twin mount but more or less at random.

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

0317 Target was showing the same size pip on radar as before firing
     so decided he needed some more attention. He had been calling
     the beach 9000 yards away for help so decided to go in on the
     ST to get close range shot and avoid his guns. Dove at range 4500.
0346 With periscope bearings, ST ranges and TDC set up steady on we
     fired #5 tube. Torpedo ran hot, straight and normal and was
     tracked out on correct bearing by sound but nothing happened.
     Depth set was 6 feet, sea was fairly rough (6 - 10 feet). When
     #5 torpedo was noted to run under, decided to turn and fire
     three Mk 18's at zero depth cross-sea.
0348 Reversed course. Made ready three tubes aft. Observed target
     still showing 3/4 knot at range of 520 yards.
0353 When range was 750 we fired 8, 9 and 10 tubes.
0354 Observed, felt, and heard torpedo explosion and we felt certainly
     this should finish him. When smoke cleared away target was still
     seen although lower in water. Gurgling noises and breaking up
     noises could plainly be heard.
0400 Heard two explosions which may have been target's depth charges.
     Came to 45 feet to get SJ on him. SJ had him range 2510 and
     while we were making sweep target sank. Loud crackling and
     breaking noises were heard and where good pip showed only seconds
     ago there was now nothing.
0406 Two loud explosions close aboard which could have been either
     aerial bombs or his depth charges. All this time the breaking
     up noises could plainly be heard. Nothing could be seen through
     ST scope and only radar contact was AGUNI SHIMA ten thousand yards
     away. So went to 150 feet and rigged for depth charge.
     I think this target sank for the following reasons:
     (a) Three torpedo hits seen and heard.
     (b) Although dark we were able to see him through #1 scope
         from time of diving until just before last explosion
         and radar sweep.
     (c) Very loud breaking up noises ½ hours after Mk. 18 explosion.
     (d) Loss of radar contact at very close range (2500 yards)
         when we had been on him for several hours.
0600 Secured from depth charge stations.
1200 Posit: 27-03 N 126-52 E.

(C) WEATHER.

The weather seemed to vary directly with the distance from land.
When in close the weather invariably was clear, calm and pleasant. As
soon as radar lost land contact the skies clouded up, the winds blew up
a good sea and this condition would remain until we headed back. In
general, weather was overcast shifting in a few hours from calm and clear
to cloudy and overcast.

(D) TIDAL INFORMATION.

Set encountered below 28° N was from 010° T to 020° T, velocity 3/4 to
1½ knots. Above 28° N the set was 045° T instead of the usual 012° T.

(I) MINES.
    Sighted drifting mine 27-17 N 125-58 E but rough seas made it
    too risky to attempt approach on it.
    Second drifting mine 26-40 N 125-10 E which evidently was dud as
    we hit it with the SO several times.

(J) ANTI-SUBMARINE MEASURES ENCOUNTERED.
    No radar equipped planes were encountered.
    An anti-submarine sweep by four small patrol craft was twice
    encountered.
    One anti-submarine patrol vessel searching with echo ranging was
    encountered and attacked in the pass between OKINOERABU JIMA and YORON
    JIMA. This was after a night we had spent on surface close in to the
    beach at OKINOERABU JIMA.

(K) DEFECTS AND DAMAGE.
    (1) #1 Generator Cooler: Outboard plug blew out of #1 generator
    cooler at 400 feet thus grounding out #1 generator at cable terminals.
    It is recommended that suitable protective shields be installed over
    terminal boxes.
    (2) Master gyro and Auxiliary gyro: Both gyros lost vacuum. It
    would be helpful if spare rotors were provided in "on board" spares.
    (3) #4 Main Engine overboard exhaust: #4 main engine overboard
    exhaust valve gasket burnt up when auxiliary engine circulating water
    overboard valve became loose from its stem. This gasket was replaced
    at sea.
    (4) Main Motors: #3 main motor brush rigging is excessively
    noisy. Cause undetermined - possibly high commutator bar.
    (5) Periscopes: (Number 2) This periscope is useless in high
    power until it has been exposed over thirty seconds. The oil seal on
    the hoisting piston is inadequate and there has been a large volume
    oil leakage past the piston ever since the beginning of the patrol.
    In its present state of development the garlock packing of the hull
    gland is not satisfactory.
    (Number 1). The hull gland packing is unsatisfactory.
    In order to prevent excessive leakage the gland must be tightened so
    that it is almost impossible to rotate the scope.
    There is a rattle in the shear structure of such volume
    as to make standard speed submerged a hazard.
    (7) Torpedo: During this patrol a split load of Mk. 23 and Mk.
    14-3A torpedoes were carried forward and Mk. 18-2 torpedoes carried aft.
    Performance of the Mk. 18-2 torpedoes was very satisfactory. With
    the exception of two dead battery cells (cell #62 torp. #57862 and cell
    #23 torp. #57786) no difficulty was experienced in carrying out the
    prescribed routine upkeep.

A hot run occurred in #1 tube (Torpedo # 39881) when
firing circuits. Despite constant warnings and concentration upon
instructions contained in "Routine, Maintenance For Submerged Torpedo
Tubes", the interlock was broken and ready to fire lever raised before
the impulse air was bled down. The hot run that resulted when the
firing key was hit in attempting to bleed down the 225# solenoid air
line, was of short duration and with the exception of a flattened nose
on the war head, the torpedo sustained no serious damage. The
heat liberated in the tube warped the water check valve slightly so
that it failed to seat properly. This defect was remedied by the ship's
force and operated satisfactorily in subsequent torpedo attacks.
No other difficulty was experienced with the air torpedoes carried.

(L) RADIO.

(1) Material: Two failures of the TBL-7 occurred. Symptoms of
the first were: failure of the first intermediate amplifier tube to
light, with no current readings past the master oscillator. Operation
on intermediate frequency was satisfactory. Trouble was traced to
switch S-6, a snap type which was jammed in the intermediate frequency
position.
The second failure, which came just as one of the regularly
schedule weather reports was to go out, was also a switch failure.
Switch S-1A and S-1B in the master oscillator oven had jumped its
contacts, due to the friction clutch on the extension rod coming loose.
The M.O. then had no grid tank. Symptoms shown on the front of the
panel were satisfactory lighting of all tubes, and a healthy M.O. plate
current, but no subsequent plate current readings. Further, a beat note
could not be obtained from the master oscillator and the frequency meter.
No receiver troubles were encountered. The performance of the RBH
in the wardroom was satisfactory, with the San Francisco evening news
received each evening. The RBS, although a very sensitive receiver,
tended to show frequency drift, and constant attention was necessary to
keep it on the schedules when it was used for them.
A second mixer switch has been installed, and it is planned to mix
the two RAL's in one, and the RBS and the RAK in the other.

(2) Reception: The following table will indicate the fre-
quencies used on station to the best advantage in the reception of the

(II) RADAR DEFECTS AND DAMAGE.

SJ: The routine amount of work was done on the SJ-1, with no
major defects noted. A ringtime was taken every day with the OBU
wavemeter, and when the lowered value for this characteristic indicated
it, a tuneup was done. The value of the OBU cannot be emphasized too
much. Its ability to provide an echo in resonance with the SJ so that
the receiver tune can be checked without target echoes is a great aid.
Minor defects were all concerned with tube failure, with the only
trend noted as being toward rectifier tubes. The regulated rectifier
tubes especially seemed prone to failure, four going out, plus two bad
tubes found in the spares. Four of the 5U4G's were lost in the base.
Performance of the gear was satisfactory. Maximum ranges obtained were:

Submarine                               15,000 yards
150 ton lugger                          15,000 yards
Jap DD                                  20,500 yards
Small patrol vessel                     10,000 yards
Lend (Formosa)                          95,000 yards

The SJ is an excellent navigational aid but its usefulness as
such would be increased a hundred fold if the ranges were measurable
out to 80,000 yards.

ST: The material performance of the ST was satisfactory. A variable
frequency wavemeter such as that furnished for the SJ-1 is desired for
the ST. The OBU was tried on the ST with poor results. Maximum ringtime
was obtained at points where no crystal current was observed on the meter.
Operational performance gave the following maximum ranges:

Katori cruiser                          11,100 yards
Land                                    30,000 yards
Jap DD                                  5,000 yards (not a maximum)

SD: No matter how you slice it or how many times you modify it,
it is still an SD radar. It is not even good for searching where the
enemy isn't. I have felt the need for a reliable and secure air search
radar more keenly on this than on any previous patrol. Skies were
almost continuously overcast and when picked up, planes were always
uncomfortably close. Lack of adequate warning is a serious handicap
and will become so more and more as we move in and the enemy has smaller
and smaller areas to search. I can think of no piece of equipment
aboard submarines which is more urgently needed than an air search radar.

SPA - APR: The only failure of the SPA or APR was with the SPA
pulse analyzer when the power transformer, reference symbol T201, Galvin
Mfg. Corporation Drawing or Specification number 25046383, burned out,
tube 2X2/879, burned out, and resistors, R 201 and R 202 burned out.
The probable cause of the transformer and resistors burning out was
the failure of tube 2X2/879. The trouble was corrected by renewing the
tube, transformer, and resistors with spare parts from the equipment spares.
It is recommended that submarines be furnished a 30 megacycle signal
generator to use in aligning the IF stages of the APR receiver and to check
the sensitivity of the receiver when on war patrol. At present it is im-
possible to determine whether or not the APR receiver is operating satis-
factorily on patrol due to the lack of suitable test equipment.

(N) SONAR MAJOR DEFECTS AND DAMAGE.

The hand train for the QB has developed a clicking noise. The
bearings were removed and cleaned to no avail. This will be inves-
tigated during the refit.
The JK-QC receiver picks up a high pitched whine from the ST.
The tone of the whine varies when the pulse repetition rate of the ST
is varied. It was temporarily cured when a bad tube in the IF of the
receiver was found. Subsequent use brought the whine back, and the
former remedy has not removed it. This is an item on the refit list.
No other defects were noted.
Operational performance of the gear was, in general, satisfactory.
This run tended to confirm our suspicions that the JP outperforms the
supersonic gear only on large targets, as for example the Katori whose
screws were tracked out to 20,000 yards by JP, but only to 12,000 yards
by JK or QB. On light targets whose screw noises are more towards the
supersonic the JK is superior.
Sound conditions were uniformly good, except for the occasional
presence of shrimp and porpoises. The absence of layers undoubtedly
contributed to this, as did the lack of shallow water.

(O) DENSITY LAYERS.

None encountered. Cards forwarded as per current instructions.

(P) HEALTH, FOOD AND HABITABILITY.

The food was of the usual high standard provided the submarines.
The ventilation in the forward torpedo room is unsatisfactory and
conductive to ill health. There are only two exhaust louvres in the
compartment; one in the officers shower and one in the officers head.
A compartment which berths sixteen men needs some positive exhaust
from the compartment.

(Q) PERSONNEL.

(a) No. of men on board during patrol | 75
(b) No. of men qualified at start of patrol | 42
(c) No. of men qualified at end of patrol | 50
(d) No. of unqualified men making 1st run | 30
(e) No. of men advanced in rating. | 1

This is my first war patrol without a Filipino mess boy aboard.
The cheerfulness, interest, and high standard service of the Filipino
boys added a great deal to life in the Forward Battery. They were
excellent submariners and fine shipmates. It is with regret that we note
their departure from submarines.
This patrol was the first for 30 and marked the return to combat
duty after many months for the rest of us. The performance of duty by
the old hands and the enthusiasm of the new men left nothing to be
desired.

(U) COMMUNICATIONS AND SONAR COUNTERMEASURES.
Communications
(1) No enemy transmissions were intentionally (on our part)
intercepted.
(2) We found heavy jamming (generally beam) on 6045, with occasional
random CW on 9090. On several of our transmissions we found heavy random
CW on the ship to shore frequency, with 8470 generally more prone to
this than 4235. Jamming was more noticeable in the mornings, about
equally heavy on 1230 and 8470. NFM was never contacted in the morning
and only twice in the evening. Evening transmissions went off with more
dispatch than the morning average morning time being 101 minutes and
62 minutes for the evening with one 2½ flail accounting for the high
morning average.
(3) Our only deceptive tactics were slow, deliberate, sending,
and a steadfast refusal to transmit without receiving authentication
from the station giving us "K". If shore stations could be taught
(a) authenticate when answering a call-up (b) do not ask ships to send
V's (c) to break in when a group is missed, transmission time would be
materially shortened.
Only apparent attempt at enemy deception was when someone, using
VAK-1, told us to go ahead and, when asked for authentication, gave us
the same authenticator as we gave him originally. (It didn't work).
(4) No comments.

Sonar Countermeasures
(1) Enemy pinging heard was all on 17 KC from patrol boat, cruiser,
and its escort DD.

SUBMARINE DIVISION EIGHTY TWO

Care of Fleet Post Office,
San Francisco, California.
25 March 1945.

From: The Commander Submarine Division EIGHTY-TWO
To : The Commander-in-Chief, United States Fleet.
(1) The Commander Submarine Squadron TWENTY.
(2) The Commander Submarine Force, Pacific Fleet.
(3) The Commander-in-Chief, U. S. Pacific Fleet.

Subject: U.S.S. SPRINGER (SS414) - Report of War Patrol
Number ONE.

1. The first war patrol the USS SPRINGER was spent
in the OKINAWA GUNTO area. This war patrol was of fifty (50)
days duration of which twenty-six (26) days were spent in the
operating area.

2. Despite thorough area coverage only two contacts
worthy of torpedo fire were made. The first against a KOTORI
Class cruiser and destroyer could not be closed to an attack
position because of an unfavorable course change. SPRINGER sur-
faced, after this frustrated attack, but was forced to dive twice
by planes, probably from the cruiser, so that successful pursuit
was denied. The other contact was attacked.

SUMMARY OF ATTACKS
3.
Attack No. 1 is covered in a supplement to this report.

Attack No. 2. Three ships were contacted by radar at 2355
yards on 17 March. Tracking was begun on one ship which gave
evidence of having radar similar to our SJ. As tracking progressed
the other two larger ships were seen to have changed course to
westward. Contact was lost on these two ships and could not be
regained, despite a search in this direction. Contact was re-estab-
lished with the ship first tracked, and position was attained for
a night surface radar attack. Four torpedoes (MK 14-3A and MK 23)
were fired at what appeared to be a DD or CM (EU). Range at firing
was 3000 yards; torpedo depth set at 6 feet; track angle 90° (S)
and torpedoes were fired along the rough of the sea. Two hits were
observed from the bridge.

Attack No. 3 followed attack No. 1 by forty-three minutes
and was delivered against the same target. As the result of the
first attack the target practically stopped but did not sink.
Inasmuch as the target was calling a shore station with search-
light and firing his guns at random, SPRINGER dove to deliver the
coup de grace at close range using the ST periscope and radar.
One MK 14-3A torpedo was fired at range 900 yards with depth
set at 6 feet. Sound reported the torpedo ran out to and then
under the target.

Subject: U.S.S. SPRINGER (SS414) - Report of First War Patrol
(4 February to 25 March 1945).

1. The first war patrol of the SPRINGER, under the com-
mand of Commander R. Kefauver, U.S. Navy, was conducted in the Okinawa
Gunto area.

2. The SPRINGER on her first war patrol had few opportuni-
ties to attack the enemy despite thorough area coverage. A series of
persistent attacks on what was estimated to be a destroyer or mine-
layer sent her to the bottom.

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

4. The Commander Submarine Force, Pacific Fleet, congratu-
lates the commanding officer, officers and crew of the SPRINGER for
this aggressive, successful war patrol. The SPRINGER is credited with

(A) PROLOGUE.

     SPRINGER arrived GUAM from first war patrol on 25 March 1945 and
was assigned to CSS-20, U.S.S. PROTEUS and CSD-82 for refit.
     The refit was more than satisfactory. The SPRINGER crew and officers
returned from rest camp to a boat which was scrupulously clean and
shipshape. To the U.S.S. PROTEUS and RELIEF CREW SUBDIV-82 we extend
a hearty and grateful well done.
     Commencing April 13, SPRINGER received normal training period under
Commander L. T. STONE, U.S. Navy.
     Three officers, Lieut. J. B. GRANT, Lieut.(jg) C. J. GIBSON and
Ensign R. L. MYERS were detached, Lieut. (jg) GIBSON, twenty-four hours
prior to sailing due to acute appendicitis. Replacements were Lieut.
J. J. EARLEY, Ensign E. J. GAINES and Ensign J. C. MEYERS.
     Readiness for sea 20 April 1945 as Task Unit 17.24 in Coordinated
Attack Group 17.24 with U.S.S. TREPANG and U.S.S. RATON.

April 28.
0135 Decided to take a look at TOLEI Harbor on FUKUE SHIMA on the
      chance that something may come out. Notified TREPANG and
      RATON of my intentions.
      With 3 saturated pips on us at 76, 97, and 152 mcs., dove and
      started in to KURO SHIMA. I intend to be due south of this
      small island at dawn so as to cover both southern approaches.
0430 First accurate fix placed us 1.3 miles east of intended posit
      but in center of SE channel.
0515 Sighted one big DD and a large ship similar to LST type, page
      141 of ONI222-J, range 7500 yards. This ship seemed much larger
      than the pictured 1500 tons and he was making 16 knots. We
      could not get closer than 6500 yards with a 115° port angle
      on the bow as he hugged the coast line of FUKUE SHIMA very
      closely. Three channels and we picked the wrong one!
0625 Heard 14 explosions which might be TREPANG or RATON getting
      into them. Hope so.
0757 Sound picked up pinging 250° T which is the bearing our two
      targets should have been on.
0816 Posit: 32-32N. 128-49 E. Sighted DD at range 8250 bearing
      250° T with zero angle on the bow. Lovely position.
0823 With range 4500 decided to ease off the track. We just got
      started when target turned toward and gave us a 10° angle on
      the bow. Decided that down the throat was only solution
      so headed towards again.
0826 With 1700 yard range raised scope to fire but found he had
      very kindly changed course to give us a 65° starboard angle.
      Made quick change in set up and at
0827-30 Fired three torpedoes with 50° right gyro.

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

0828-12 First torpedo hit. Target was either blown around or turned
           toward listing heavily to port so we went deep rigging for
           our first shellacking.
0829     No screws, no depth charges. Only crackling and popping noises
           so came back up for a look.
0830     Observed target dead in water with his after 1/3 bent and at
           90° angle to keel. He was not sinking so decided to give him
           some help. (Photographer took movies and several still shots).
0854-30 In position to fire with range 880 yards bearing steady, course
           steady, gyro angle 4½. Fired #5 tube. Torpedo was observed
           to run 5 - 10 yards ahead. Two lifeboats and one life raft
           now in water.
0855     Sighted JAKE hovering over target.
0855-30 Fired #6 tube with same result as #5 range 785. This fish
           passed directly beneath loaded life raft causing much excitement
           and confusion among said occupants, but no damage to either
           target or raft. Decided to turn and open out for a stern shot.
           All hands seem to agree that it's time to abandon ship and noted
           two of the officers come out forward hatch all dressed up with
           swords, sashes and all. One had a sash which trailed from the
           main deck clear to the waters edge. Quite a touching scene and
           as everyone seemed ready to meet their master, at
'0902-20 Fired #8 tube at stack. Range 950.
0903     Observed hit under #1 turret which eliminated the bow and the
           two loaded life boats which were still alongside. JAKE was an
           interested and ineffective witness probably muttering their
           well known "What a deplorable situation".
0904-30 Target observed to upend and vanish with 180 dive angle.
           Posit: 32-34.5 N. 128-52 E. Definite information as to
           what type this target was is requested from Fleet Intelligence
           Center.
1200     Posit: 32-27.5 N. Long. 128-40 E.
1245     Sound picked up screws at 295 T. Observed two trawlers and
           two planes evidently searching. Went deep to avoid. In view of
           low run and fact that we have been down since 0135 decided to
           let these pass unmolested.
2000     Surfaced.

April 29.

0635     SD and SJ contact closed to 3 miles. Dove.
1200     Posit: 32-39 N. Long. 125-14 E.
1240     Surfaced in nice thick fog.
1530     Sighted two floating mines; posit: 33-02 N. 124-51 E.

April 30.

1015     Radar contact bearing 078°T range 15,000 yards. Commenced
         tracking what appeared to be one large ship with two escorts.
         Sent contact report to TREPANG and RATON. Could only get
         PICUDA answered also but she was too far away for
         any immediate action. Continued tracking these targets on
         surface aided by dense fog. Sent contact report to TREPANG
         on every leg of zig plan.
1200     Position: 34-28 N. 124-18 E.
1205     TREPANG reported contact and that she'd be on port flank.
1220     Commenced approach telling TREPANG we were attacking.
1239     With range 4750, convoy zigged toward putting bow 1,500
         yards ahead bearing 040 relative, angle on bow 90 starboard.
         Had now determined convoy to be one large freighter with
         DD escort and DE escort.
1240     We were standing by to fire when fog lifted as a curtain
         leaving us very naked in full view of DE bearing 130 relative,
         angle on the bow 110. DE turned toward firing all his guns.
         Changed set up to fire down the throat at him and dove with
         escort angle on the bow zero, relative bearing 178. Dove.
         Fired 8, 9, and 10 tubes. These torpedoes were fired solely
         in an effort to disrupt his intentions and confuse the impending
         depth charging.
1241     Made ready #7 tube. Went deep, 200 feet, rigging for silent
         running.
1241-30  Fired #7 tube.
1242-30  Received first of 27 rather close depth charges.
1243     Last depth charge.
1245     Heard what sounded like torpedo hit. Possibly TREPANG.
1245     All quiet so came up for look. Once more fog had set in
         and all clear on ST.
1341     Surfaced.
1351     Received message that TREPANG had got one hit.
1355     Target was now dead in the water with escorts circling her
         carefully. Decided to await dark as this fog was definitely
         unreliable.
1425     Fog lifted and visibility was now 8 - 10 miles.
1643     Observed DD chasing TREPANG.
1720     Received message that TREPANG was going in to attack. Escorts
         had now shoved off about 8 miles evidently looking for us.
1950     TREPANG sunk target.
2300     Sent our 1st to CSP giving results to date.
2355     Headed north for aircraft contact.

May 1.
. 0030 Radar contact 210°T, 13,000 yards. Commenced tracking.
Evidently two spit kits out on A/S sweep or two escorts
encountered with target searching area. Sent message to
TREPANG. Unable to raise RATON all day.
0215 Second pair picked up 300°T, 6,140 yards. Bent on four
mains and hauled out.
0600 Down.
1200 Posit: 35-44 N. 124-05 E.
1930 Surfaced.
2100 SJ contact 36,000 yards. Closed to 1800 yards to find 2 small
fishing boats. Hauled out to northward.

May 2.
. 1200 Posit: 35-15 N. 123-41 E.
2000 SJ contact, 3 ships 270°T, range 36,000. Commenced tracking
and sent contact report.
2116 Received word that RATON was busy pursuing another contact.
TREPANG was too far away to be able to assist.
2243 Manned night battle stations. There is one large ship with
two smaller ones, both on his starboard bow.
2251 Range 4,000 yards. Determined target to be either DD or DE
with two small ships conducting A/S sweep.
2254-20 Range 3310, fired tubes 6, 5, 4, and 3 depth set 6'.
2256-53 Heard 1st explosion (rather light).
2257-02 Observed and heard 2nd and 3rd heavy explosions.
2300 Ship was shaken thoroughly by tremendous explosion. Target
disappeared from screen. Posit: 33-58 N. 122-58 E.
2315 Started in on two remaining pips. Closed to 3600 yards and
saw that targets were small patrol craft. Hauled out to
northward as they are now thoroughly alerted and I think it
a good idea to avoid detection

May 3.
0205 Received word that RATON sunk 5,000 ton AOG.
0600 Down.
1200 Posit: 35-03 N. 124-00 E.
1900 Surfaced.
2100 R/C contact at 60,000 yards. Began to close.
2145 S/H contact 119 T. 20,480 yards, commenced tracking. TREPANG
has a contact and RATON is well to north. Inasmuch as we have
reported that we cannot join TREPANG did not send any contact
report.

2235 Night battle stations. Determined target to be DD again out
     on A/S sweep. Target was pinging and zigging at 10½ knots,
     base course 250°T.
2245-40 Fired 6, 5, 4, and 3 tubes.
2247-40 Observed and felt three hits. This was followed shortly by
     a huge underwater detonation.
2309 Observed huge flash on horizon to westward. This was followed
     by sound of underwater detonation wave. This was end of
     successful attack which TREPANG started several minutes ago.
2328 Target had capsized but was still on PPI so closed to 1200 yards.
2328-30 Fired #1 and 2 tubes at target dead in water ½ R and L set
     on torpedoes. Missed.
2340 Circled target range 1900 when suddenly target disappeared.
     Posit: 34-38 N. 124-15 E.

May 4.

0130 Closed large oil slick with lots of debris looking for
     survivors. Picked up papers but no prisoners. Cleared area
     to north.
     I think that this was one of two, two stack destroyers
     reported by aircraft earlier in the afternoon for the follow-
     ing reasons. His position at contact was a logical possibility
     based on his earlier position. TREPANG sank one of two patrols
     together to the westward of us at 2309, 3 May.
     Next day aircraft reported one destroyer and one patrol type
     operating together. Of the original five these were the
     remaining two available for patrol.
0330 Sent second to ComSubPac regarding Rustlers results to date.
0515 Dove.
1200 Posit: 34-36 N. 124-44 E.

(G) AIRCRAFT.
Two aircraft encountered on morning of 5 May when leaving the
YELLOW SEA are suspected of being friendly. They were not following
the newly established procedure of remaining outside 8 miles until
exchange of recognition. This procedure should be enforced especially
in areas 9 and 12.

(I) MINES.
In direct contrast to usual YELLOW SEA patrols we sighted only
six mines this patrol.

(J) A/S MEASURES AND EVASION TACTICS.
Nothing new in the way of Jap A/S was encountered. They are
evidently concerned about our activity on the traffic route to SHANGHAI.
We should be on the alert for more efficient and better equipped patrols
in this area. The DD's and DE's at present patrolling this area are
using long legged zig zags and are very vulnerable to tracking and
attack from the quarter. Torpedoes on surface on a dark night offer
more chance of success, I think, than other methods of attack.

(K) MAJOR DEFECTS.
1. On 16 May the Auxiliary Engine which was carrying a zero float
on the battery showed signs of losing the load and the engine was
secured to remedy this condition. At this time all temperature and
pressures were normal. Suspecting Governor trouble, the spare Woodward
governor was installed, and the engine started. Immediately on rolling
over, very loud knocks could be heard and the engine was stopped.
Investigation revealed that #7 lower connecting rod bearing wiped and
crankshaft broken cleanly at about the middle of the journal. No
explanation has been found for this failure.
The engine underwent a major overhaul during the last refit. Total
engine hours were 1143.8. Hours since last overhaul 383.7
2. Port stern tube glands leak excessively. Cause is undetermined
but stern tubes should be repacked in refit period.
3. D.R.A.I. - Speed input motor noisy, apparently due to dirty
slip rings. Motor was inspected and mechanical operation was found to
be all right. Complete overhaul has been requested.

(L) RADIO DEFECTS AND DAMAGE.

Bridge IMC switch froze in the talk position, effectively
cutting off all other IMC - 7MC communications. Since this feature
is considered a fifth wheel on the bridge, the press to talk leads
were removed in the amplifier rack, to be repaired in refit.
No radio defects were noticed.

(M) RADAR DEFECTS AND DAMAGE.

Routine amount of trouble was experienced with SJ. All troubles
were tubes and all tube troubles concerned rectifier tubes. High
voltage tubes failed twice. PPI 705A rectifier went out. Voltage
regulators in both regulated rectifiers deteriorated gradually, causing
double pulsing of both ST and SJ. Replaced tubes. SJ showed low
sensitivity at beginning of sweep. Replaced TR tube and crystal.
Another tube that gave trouble was the 723A/B local oscillator
for the SJ. Then the original was replaced by Western Electric tubes,
Contract NKS-551, order number 564314-RH-2002, in a routine check, the
A-scope completely lost its sweep, and the PPI showed a half length
sweep, even with the high voltage off. In all, it was found that two of
the three spares aboard (all of that lot number) were shorted. It was
a tense moment when the third one was tried.
Switch, piece number D-3, refused to make contact one evening
before surfacing. It was hurriedly shorted out, and later investigation
showed the interior to be well corroded and the insulation crumbled.
This switch was replaced at the last refit, and lasted just 5 weeks.
Tube V(4)6L6G in the PPI shorted, causing F4 to blow, and
resistors R24 and R25 to burn out. This had happened once before
when terminals 30 and 31 came loose and shorted out. No apparent cause
could be found this time, however. Symptoms were absence of sweep on PPI.
Incidentally, the communications department boasts the only
battle damage on board, having sustained a direct hit on the SJ reflector
from a machine gun bullet on the attack of April 30. The department
steadfastly maintains that the DE knew it was shooting at the most
important part of the boat but is finding trouble gathering adherents
to this theory outside the Communication Gang.
Extra ordinary ranges were obtained with the SJ in the YELLOW
SEA Area, due, it is believed to a temperature inversion. On the night
of 1 May, 2035(I), posit: 36-07 N, 124-05 E, SJ made contact on two
fishing vessels, estimated tonnage 40 tons each at 38,000 yards, true
bearing 147 T, weather conditions: wind 330, force 1 knot, barometer
3005, air temperature 48, sea temperature (main engine injection) 53,
sea dead calm, low haze, but no high clouds.

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

On the following night at 1850(I); position: 35-11 N, 123-33 E.,
SJ made contact on destroyer, range (est) 60,000 yards, true bearing
250 T, relative bearing 070. Tracking was commenced at 35,000 yards,
using lobe switching, signal E3 to E4 (T.D.C. had to use one-tenth
ranges and speeds - see remarks section). Wind 1 knot from 270,
barometer 29.96, air temperature 57, water temperature (main engine
injection) 57. Perfectly clear, sea state 1.
Other range obtained were more or less normal including:
Land 95,000 yards
Submarine 15,000 yards
Medium AK 22,000 yards
DD 20,000 yards

SD-5: The SD was used more this run than ever before, principally
during the lifeguard period. It is a sturdy piece of gear, much like
the horse and buggy, and gave about as much trouble. One 2 x 2 in the
receiver unit shorted out, blowing fuse F903. The transmitter tubes
(801A) were replaced after 550 hours, when reburned echoes were noticed
as much weaker.
Maximum ranges obtained 45 miles on B-29's, 35 miles on F6F's,
and zero on a ZEKE that rode the beam in the morning of 14 May, about
50 feet off the water.
Routine tube changes also included TR tube (1960), and several
of the I.F. tubes (6AC7's) to obtain maximum echoes.

APR-SPA: V201(2x2) High voltage rectifier shorted, burning out
R201, and killing the SPA entirely. Replaced both, and saw unit back
to normal.

BN-ABK: No defects or damage noted.

(N) SONAR GEAR AND SOUND CONDITIONS.

No sound conditions were noted out of the ordinary. All cases
of echo ranging picked up were on 17 kc., including the destroyer of
29 April, and that of 2 May.

(O) DENSITY LAYERS.

Density layers were found as follows:

(U) COMMUNICATIONS AND RADAR COUNTERMEASURES.
:-
1. No intercepts of enemy signals were made on radio, other
   than an excited Japanese voice on 40 mc. immediately after
   the attack on the night of May 3.
2. Heavy jamming noted on 8470 at 0600Z, 7 May, consisting
   of random CW. This was only occasion Nips gave trouble on
   ship-to-shore frequencies.
   Very deliberate random keying of MCW was encountered on
   4475 during the strike of May 11. Very effective, it cut
   all voice communication with our dumbo. Steady Jap CW
   at other times.
   Jap CW transmissions were found at all times on all Topac
   frequencies but none troublesome enough to prevent communications.
3. No deceptive tactics noted or employed. In one instance it
   was necessary to disregard an incorrectly authenticated call up
   in order to accept a message from a boat entering our area.
   This is a dangerous situation and is needless.
4. No photographs of interest were taken.

Radar:-
1. Intercept of radar signals are given in the APR log. It
   is noted that not one of the ship contacts showed any radar
   that we could identify as such. No aircraft radar were
   definitely received either.
2. No jamming was noted.
3. No deceptive tactics employed or encountered.
4. A roll of 35 mm. was taken of possible radar installations
   on KAJI SHIMA. Visual inspection showed what appeared to be
   three ladder type antennae.

(V) REMARKS.

Reception of the Fox schedule this patrol was definitely
improved over the previous run (in the Okinawa area). It was found
that 9050 and 9090 were about equally reliable frequencies, being
best during the period 0600 to 0200Z. Analysis of the reception log
shows that 9050 and 9090 were used during the period 0800 to 0200
almost exclusively, and 13655 from 0200 to 0800. No other frequencies
were used or were necessary. All SubPac serials were copied.
Our transmissions went off with little delay, too, with average
transmission time of nineteen minutes. 8470 was used exclusively for
ship-to-shore contact when outside the entry lane to GUAM.

Once again, a plan is made for a resonant type echo box for the
ST similar to the ones supplied for the SD-5 and SJ-1. Much time is
lost in tuning during periscope exposure when there have been no
previous targets to peak the gear up on.

During operations in the YELLOW SEA, on two occasions enemy
vessels were picked up by radar at ranges beyond 30,000 yards. In
tracking at such ranges it was found that satisfactory results could
be obtained by using one-tenth scale on the TDC. This method elim-
inated the mental gymnastics necessary when the halving or quartering
method is used.

It is suggested that then message is sent to boat ordering them
to report the date for refit the administrative command assigned for
the refit be given. This would greatly facilitate necessary paper
work and eliminate last minute flail upon arrival.

FIRST ENDORSEMENT to
C.O. USS SPRINGER (SS414)/A16-3,
Serial 021 of 18 May 1945.

From: The Commander Submarine Division ONE SIXTY ONE.
To : The Commander in Chief, United States Fleet.

(2) The Commander Submarine Force, Pacific Fleet.
(3) The Commander in Chief, U.S. Pacific Fleet.

Subject: U.S.S. SPRINGER (SS414) - Report of Second War Patrol,
comments on.

1. The second war patrol of the U.S.S. SPRINGER was conducted in the
YELLOW SEA. The SPRINGER was a unit of a coordinated attack group consisting of
the SPRINGER, RATO and TREPANG. Commander R. KEFAUVER, U.S.N., Commanding
Officer of the SPRINGER was in command of the coordinated attack group. The
patrol was of twenty-nine (29) days duration with seven (7) days being spent in
the originally assigned area during which time all but two torpedoes were
expended. The SPRINGER was then assigned life guard duties for seven (7) days.

2. During the seven days in the area, nine contacts with groups of
enemy ships were made. Four of these contacts were trawlers or fishing boats,
too small for torpedo targets. An AP with an escorting DD was sighted while
submerged on the first day in the area but could not be closed. The remaining
four contacts were all developed into torpedo attacks.

Attack 1, 2, and 3.

On the morning of 28 April while submerged, pinging was detected.
Nineteen minutes later a single TERETSUKI class destroyer was sighted apparently
on an A/S sweep. As the approach developed, it appeared that a down the throat
shot would have to be accepted. However, target zigged just before firing. A
quick set-up was obtained and three steam torpedoes were fired at 1500 yard
range, set at 6 foot depth, with 65° starboard track. Gyro angles were large,
52 to 58° right. The first torpedo hit aft. The DD lay dead in the water with
the after third of the ship bent upwards nearly 90 degrees. The crew started
to abandon ship which did not appear to be sinking.

Twenty-seven minutes later the SPRINGER having maneuvered into
800 yard range fired two steam torpedoes from the stern tubes on an 80° track
with 180 gyro angles, depth, 6 feet. Both missed slightly ahead. Six minutes
later another steam torpedo was fired from the stern tubes. This torpedo hit
under No. 1 turret eliminating two loaded lifeboats alongside. Target sank verti-
cally a minute and a half later. During the last two attacks a JAKE plane was
observed flying around the target but apparently had no bombs as it made no
attacks. Four hours later a "Hunter-Killer" group composed of two trawlers and
two planes searched the area, but SPRINGER avoided detection.

                Attack No. 4.

                On the morning of 30 April, in a dense fog, radar contact was made
on a three ship convoy which later turned out to be an AP or AK escorted by a
DE and a DD. After tracking for two hours SPRINGER started attack. The TREPANG
meanwhile had taken position on opposite flank. Just before reaching firing
position, the fog suddenly lifted exposing the SPRINGER to a full view of the DE
escort which immediately turned towards her firing all guns. SPRINGER put her
stern to the DE and dived, firing three steam torpedoes "down the throat" at a
1000 yard range. This was purely a defensive measure with "hopes", but all
torpedoes missed. Two minutes later twenty-seven (27) rather close depth charges
were dropped, but no damage was sustained by the SPRINGER. During this period
TREPANG attacked and got one hit in the AP or AK. Two hours later SPRINGER sur-
faced in the unreliable fog and together with the TREPANG played hide and seek
with the escorts, waiting for an opportunity to polish off the main target.
Late that night the TREPANG made another successful attack on the target while
the escorts were apparently looking for the SPRINGER.

                Attack No. 5.

                On the night of 2 May radar contact was made on three ships at
36,000 yards. A night surface radar approach was made. At 4,000 yard range the
ships were identified as a DD or DE with two smaller patrol boats on an A/S
sweep. At 3,000 yards range four steam torpedoes, set at 6 foot depth, 5° left
gyro, were fired from the bow tubes on a 100° port track at the DE or DD. Two
hits were heard and observed and a possible third hit was heard. Three minutes
later target disappeared from radar screen. SPRINGER closed the point where
target had been. Only the two small patrol boats remained and being too small
for torpedo attack SPRINGER retired.

                Attacks 6 and 7.

                On the night of 3 May radar contact was made at 10 miles on a single
destroyer on an A/S sweep. A night surface radar approach was made at a range
of 2,700 yards, four steam torpedoes, with 20° right gyro, depth set at 6 feet,
were fired from the bow tubes on a 100° track. First three torpedoes were
heard and observed to hit. Target capsized but did not sink. Forty-three
minutes later two more steam torpedoes were fired from the bow tubes at 1,200
yards range. Both missed. While SPRINGER was maneuvering for another shot,
target suddenly disappeared. Upon closing the point of disappearance, a large
oil slick with plenty of debris was found. Some papers were recovered from the
water, but no survivors were seen.

                3.      All torpedo attacks were well planned and executed in a determined,
resolute manner, resulting in inflicting maximum damage to the enemy encountered.

                                                                - 2 -

         4. While on life guard duty, no opportunity was presented to effect
any rescues. SPRINGER had the pleasure of witnessing four of our own planes
knock down a Jap plane. Upon closing the point of attack, the dead Jap pilot was
picked up. Search of his clothing revealed several papers which were taken, after
which he was replaced "over the side."

         5. Exceptional radar ranges were obtained in this area probably due to
atmospheric conditions.

         6. The SPRINGER was very clean and shipshape upon her return from
patrol. Her material condition is very good. She will be given a normal refit
by the U.S.S. PROTEUS.

         7. The health of the officers and crew is excellent. The morale of
all hands in this fighting ship is of the highest state.

         8. It is noted that 22 men were qualified during this patrol, 74 men
out of a crew of 79 being qualified upon her return. This is considered
exceptional.

         9. The Administrative Division Commander extends his heartiest con-
gratulations to the Commanding Officer, his officers and crew on the completion
of this excellent, well conducted and aggressive patrol, which, although of
short duration, was highly productive and very damaging to the enemy's ever shrink-
ing navy, particularly to his anti-submarine force.

         10. It is recommended that the SPRINGER be credited with inflicting
the following damage to the enemy:

                                   SUNK

         1 DD (TERETSUKI CLASS) (EC)        2300 tons Attacks 1, 2, 3
         1 DE or DD             (EU)        1000 tons Attack 5
         1 DD                   (EU)        1700 tons Attack 6, 7

                                   Total Sunk 5000 tons

Subject:    U.S.S. SPRINGER (SS414) - Report of Second War Patrol
            (20 April to 18 May 1945).

            1. The second war patrol of the SPRINGER under the com-
            mand of Commander R. Kefauver, U.S. Navy, was conducted in the
            Yellow Sea areas. The SPRINGER along with the U.S.S. TREPANG and
            the U.S.S. RATON formed a coordinated attack group with the command-
            ing officer of the SPRINGER as group commander. Lifeguard services
            were rendered in addition to offensive patrol.

            2. This very aggressive and well conducted patrol pro-
            duced eight contacts worthy of torpedo fire. In eight well executed
            attacks the SPRINGER sank two destroyers and one destroyer escort.
            The coordination of this group was excellent.

            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 SPRINGER
            for the completion of this highly aggressive, determined patrol.
            The SPRINGER is credited with having inflicted the following damage
            upon the enemy during this patrol:

                                S U N K

(C) WEATHER.
    The weather was generally good with only a couple days with
    moderately heavy swells and varying visibility.

(D) TIDAL INFORMATION.
    Most of the time was spent in the KUROSHIO with strong
    easterly currents encountered conforming with the charts.

(E) NAVIGATIONAL AIDS.
    Only two of the several lighthouses sighted turned on
    light for our benefit. HINO MISAKI and IRO SAKI burned with
    normal characteristics.

(F) SHIP CONTACTS.
    None.

(G) AIRCRAFT.
    Only four Jap aircraft were sighted during the entire patrol
    that were definitely identified. One of these was attacked by our
    fighter cover.

(H) ATTACK DATA.
    None.

(I) MINES.
    Eleven mines were destroyed. Nine by explosion and two
    by sinking. Three additional were sighted while we were on special
    missions and ignored. One type "B" buoy was sunk by gunfire.

(J) ANTISUBMARINE MEASURES AND EVASION TACTICS.
    No picket or patrol craft were sighted during patrol. Our
    aircraft have done an excellent job. One plane dropped two bombs
    after we leveled off at two hundred feet just to let us know he
    saw us.

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

(K) MAJOR DEFECTS AND DAMAGE.

HULL: No. 1 Periscope (ST). During refit after
1st patrol, April 1945, SubDiv 82 and PROTEUS pulled cylinders and
pistons through misunderstanding of request. PROTEUS not having
piston "O" rings similar to installation on SPRINGER, replaced later
type of piston and ring with obsolete types. This was not known
until it was too late to change back. During second patrol it
functioned normally. On July 1st, during morning routine exercise
of periscopes in hoist and train, it refused to raise. Port piston
was functioning normally, but starboard was frozen. After repeated
efforts scope finally raised. On attempting to lower, the starboard
piston was again frozen. After determining it wouldn't lower,
disconnected starboard piston from yoke and lowered scope with port
piston and tackle.
Repeated attempts to pull out piston with a chain fall proved
fruitless. Yoke retaining ring is stripped and probably bent. Piston
rods seem to be bent and bearing races and rings in yoke may be warped.
Replacement of cylinders and pistons, lapped to each other,
using type in #2 periscope is requested. Ship has pistons and rings.

ENGINEERING: Auxiliary Engine Exhaust Gasket
The aux-
iliary Engine continues to burn out the #4 Main Engine exhaust
exhaust valve gasket. The gasket is always burned
in the top, outboard corner.
Removal of the immersion box inspection plate while the engine
was running revealed the following:
1. A sufficient amount of cooling water from the horizontal
spray ring flows over the valve disk in the open position,
but little or none comes from the vertical spray ring
which cools to valve seat.
2. When the engine circulating water temperature requires
closing the overboard by-pass valve, the flow of cooling
water from the spray rings practically ceases.
It is believed that a slight increase in the diameter of the
circulating water piping leading to the immersion box, and the
blanking off of the aux. Engine discharge to the compensating
system would provide a suitable remedy, and this will be suggested
during the next refit.
The gasket was replaced by our spare at sea.

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

(L) RADIO DEFECTS AND DAMAGE.

None noted. The "old faithfuls" TBL, RAK and RAL gave their
usual consistent performance. The only possible weakness is the
inclusion of the RAK in the radio allowance. Now that the low
frequency days of the past for submarines, the useful days of the
RAK are at an end. Now that submarines must guard two high frequencies
in addition to the skeds (4475 and 3310), the NPH frequencies can no
longer be fed into a mixer switch, and quick fades in the signal or
jamming on one frequency may cause important messages to be lost or
unnecessary time in waiting for a repeat. The Pearl Harbor local
frequency and the distress frequency can be covered by the RAL. It
is suggested that the RAK be replaced by an RAL or RBS.

(M) RADAR.

SJ-1: Performance: Overall performance for the run was
creditable, with a total of 5 hours lost time in making repairs. Of
this, only 1 hour and 40 minutes was lost in "emergency" repairs.
The principal use of the gear was in navigation, with constant
ranges of 90,000 - 100,000 yards obtained on land.
SJ-1 shone as an aircraft detector with ranges on aircraft
up to 40,000 yards reported. It was extremely useful in vectoring
our dumbo cover and in guiding the night missions.
Friendly submarines were contacted at a range averaging
11,000 yards.
The customary minor, but troublesome, derangement of the
various radars were encountered. Following is a list of troubles
and remedy taken:

SJ-1 Radar: Low ringtime and crystal current, low I F gain,
and false echoes at 1500 and 80,000 yards caused by C-22 (A & B) in
transmitter unit broken down. Defective crystal (IN21). Vertical
jitter on "A" scope caused by loose terminal post at terminal 21 in
range indicator. Bad focus on tube. Dynamic focus and focus video
stage had no effect, caused by defective C-R tube. No power to entire
assembly, voltage only to terminals 23 and 24 caused by failure of
main switch in main control unit. This trouble occurred twice during
the run, necessitating a final cure by wiring around the switch and
using the fuse in the main power leads as a switch. It is suggested
that the additional load of the ST radar through this switch may be
enough to overload it. A higher capacity switch for D3 is recommended.

- 14 -

— page 80 —
C-O-N-F-I-D-E-N-T-I-A-L

No intensity control on C.R. tube in range indicator caused by
defective C.R. tube. Double pulsing in the SJ and unstable tuning
caused by bad 5U4G in the "B" regulated rectifier. The same trouble
also appeared in the "A" rectifier.

ST Radar: Not used on patrol. See Section "K".

SD-5 Radar: SD was used continuously on this patrol, being
keyed at intervals from 40 seconds to 3 minutes depending upon the
tactical situation.
First contact was by SD on the DAVE which dropped two on us
making us realize that we loved this much-maligned radar very dearly.
Ranges on B-29's varied from 10 to 40 miles with recognition
out to 60 miles.
Ranges on land reached 40 miles, and in some cases exceeded
the SJ's.
No serious derangement of the gear was noted. Transmitter
tubes were changed after 607 hours of service. Several I F tubes
were replaced.

APR Intercept Receiver: (See countermeasures section for
performance). SPA scope would not focus (intermittent) caused by
increase in R116 in resistance from 0.56 megohms to 10 megohms.
Replaced.

(N) SONAR AND SOUND CONDITIONS.
Nothing unusual was encountered on sound conditions.
Material troubles were minor. QB gear twice refused to
echo range. The first time it was traced to a broken primary lead
on the power transformer, the second to a faulty keying
relay. QB-JK training went out entirely, with the main power fuses
being blown when the training motor generator was started. Trouble
was traced to a low rated fusing, and an improperly adjusted overload
relay dash pot.

(O) DENSITY LAYERS.
None located. All bathythermograph cards were forwarded in
compliance with current instructions.

(U) COMMUNICATIONS, RADAR AND SONAR COUNTERMEASURES.

Reception of Fox schedule was good and only one serial, not
pertaining to us, was missed by us and other boats.
A reception log was kept during the entire run and best
reception frequencies and times are listed as follows:

GCT                               Fox

22-24                             13655 and 9090

The relay or tape on 9090 and 9050 seemed to jam quite
regularly during the early morning hours. Reception on this run was
very satisfactory from an operator's viewpoint.

Comparatively few radar equipped planes were encountered
while innumerable land based radars were encountered within sight of
any land. It was a rare occasion when the scope was clear. Log of
APR intercepts follows:

Subject:

1. The third war patrol of the U.S.S. SPRINGER
under the command of Lieutenant Commander J.F. BAUER, U.S.N.,
was conducted off the east coast of Honshu in the Lifeguard
League during the period 16 June to 27 July, 1945, a total
of 42 days, 33 of which were on station. Although much of
the time was spent within sight of enemy shores no "all day"
dives were made.

2. Numerous air contacts were made but only four
were definitely identified as Japanese. No contacts were made
with enemy ships.

3. On 26 June, one hour and twenty-five minutes
after receiving word of a downed plane, the SPRINGER rescued
eight aviators who were crew members of a B-29. On 27 June
Lt. Col. Howard Hugos, U.S.A., command pilot of a group of
B-29's, was rescued.

4. On 9 July in Lat. 34-06 N., Long. 137-34 E., the
SPRINGER sighted and took pictures of what appeared to be a
type of sono buoy. On 11 July approximately fifty miles east-
erly of the above position, a second buoy, similar to the first
one, was sighted. Both buoys were sunk by rifle fire.

5. The SPRINGER returned in good material condition.
Refit will be accomplished in the normal time.

6. The Administrative Division Commander congratulates
the Commanding Officer, officers and crew of the SPRINGER upon
the completion of that vessel's third war patrol during which
nine aviation personnel were rescued.

(16 June to 27 July 1945).

1. The third war patrol of the SPRINGER, under the command of Lieu-
tenant Commander J. F. Bauer, U.S. Navy, was devoted to lifeguard duties south
of Honshu.

2. As a result of widespread, alert area coverage of enemy waters

cue downed B-29 aviation personnel. Both rescues were made in an efficient man-
ner, eight aviators being rescued on the first occasion and one the next day.

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 SPRINGER for this successful per-
