HISTORY OF USS BRILL (SS 330)

The keel of USS BRILL (SS 330) was laid in the yards of the Electric
Boat Company, Groton, Connecticut, on 23 September, 1943. The boat was
launched 25 June, 1944, and was christened by Mrs. P. S. Low. She was
was commissioned 26 October, 1944. First commanding officer was Commander
M. P. Dodge, USN.

The war experience of the BRILL was typical of many U.S. Submarines
built in the late months of the war to reach Pacific waters just in time
to see the battered Japanese Navy and merchant marine high-tail it over
the horizon.

After a period of intensive training in Atlantic and Caribbean waters
the BRILL departed Balboa, Canal Zone, for Pearl Harbor on 23 December
1944. She arrived in Pearl Harbor 8 January 1945, reporting to Com-
mander Submarine Force, Pacific Fleet, for duty.

On 28 January, the BRILL departed Submarine Base, Pearl Harbor T. H.
for Saipan, Marianas Islands. The passage to Saipan was uneventful
without mishap with the exception of W. P. Lavender, CMOM, USN, who
was stricken with acute appendicitis. Arriving at Saipan on 9 February,
Lavender, was transferred to the U.S.S. [UNCLEAR: TMO] for treatment. In Saipan
fuel and provisions were taken aboard and on 10 February, 1945 the BRILL
departed for her first patrol.

The passage from Saipan to the Philippine Islands were uneventful
and the only enemy contacts were U.S. Submarines returning from patrol
which literally seemed to crowd the ocean. On 15 February, land contact
was made on Hainan Island and the patrol area through Luzon Strait was made
that night. From Luzon to the patrol area the only contacts were made
several U.S. and enemy aircraft. On 19 February, land contact was made
on Hainan Island South China Sea, which was then the BRILL's first assigned
patrol area.

On 20 February, a floating mine was sighted and sunk by gun fire.
About 15 minutes after the mine was exploded a torpedo wake was sighted
approaching on the starboard quarter. The BRILL was zigging at the time
and was steadied on a course parallel to the torpedo wake and sighted. Both tor-
pedoes passed down starboard side, the first a distance of about 200
yards and the second about 50 yards.

The BRILL opened the range about 2000 yards, submerged and changed
course to head back to the vicinity of torpedo wake sighted. No sound
contacts could be made with the enemy submarine. From 20 February to 1
March, no enemy shipping was sighted but numerous contacts were made on
sailing junks.

On the night of 1 March, contact was made on three small patrol boats.
The BRILL gained a position ahead on their base course and submerged to
get a closer look in the moon light. It was thought possibly that the
three patrol boats were escorting bigger game, and the BRILL passed be-
tween two of the patrol vessels which were echo ranging and under the

— page 4 —

third which was not. Three depth charges were dropped, not close. These
charges were apparently dropped on general principles or as sucker bait
for honorable U. S. Submarine. It was decided to leave these "Sons of
Heaven" alone who were apparently looking for trouble, the water being
only 80 feet deep.

On 5 March, patrolling submerged, a large tanker with two planes
and two destroyer escorts was sighted at 12,000 yards range. An approach
was commenced immediately on the tanker but was broken off one hour later
because we were unable to close to torpedo range. After surfacing on
the fifth, contact was made on a hospital ship, properly
lighted, on an easterly course, speed 15 knots.

On 6 March, the BRILL joined company with the U.S.S. CHUB for
coordinated patrol in Tonkin Gulf. On 8 March the BRILL was driven
down by a medium enemy bomber and two depth bombs dropped but no damage
inflicted. On 10 March, contact was again made with the CHUB who also
complained of unfriendly treatment by enemy aircraft. On 15 March,
while conducting life guard duty for U.S. Bombers pounding Hainan Island,
a third torpedo wake was sighted which passed the BRILL astern about
100 yards. The torpedo was avoided at flank speed.

On 21 March, 1945 the BRILL rendezvoused with the U.S.S. GURNARD
and received an Australian Army Officer and Malayan native aboard for
special mission, then began patrol down French Indo-China Coast. On
25 March land contact was made on Sakala Island and at night the Aus-
tralian Commando and friend was put ashore. One hour later, party returned
with five natives and the entire party was taken aboard. On the night of
26 March, 1945 the BRILL arrived in Fremantle which concluded her first
patrol. A total of 62 days were spent at sea including 29 days in patrol
area. Miles steamed on this patrol was 15,339 and fuel consumed was
156,570 gallons.

After a normal refit by the Submarine Division 302 in Fremantle and
a short training period the BRILL departed Fremantle on 27 April, and
headed for Lombok Strait. Enroute, daily dives, drills, and battle pro-
blems were conducted and on 2 May, 1945 land fall was made on Bali Island.
The passage through Lombok Strait was completed that night. The BRILL's
second patrol was conducted off the East Coast of Malaya. No ship contact
worthy of torpedoing was made. Several days were spent in coordinated
patrol with other U.S. Submarines and on 4 June, 1945 the BRILL departed
patrol area and headed for Subic Bay. On 8 June, 1945 the BRILL arrived
in Subic Bay, Luzon, P. I. and patrol refit was begun by the USS HOWARD
W. GILMORE. On her second patrol the BRILL was at sea for forty two days
and in patrol area 28 days. A total of 7,892 miles were steamed and
95,410 gallons of fuel consumed.

The periods 12-24 June, was spent in refit by Submarine Division 222
and from 25 June to 2 July, training period under the supervision of
Captain R. C. Lake U. S. Navy. On 3 July, 1945 the BRILL departed Subic
Bay and headed for assigned patrol area. On 8 July the BRILL arrived
and joined company with other U.S. Submarines to conduct
coordinated patrol in the Gulf of Siam.

On 11 July, 1945 contact was made on two small patrol vessels. A
surface approach was conducted and in three attacks, eleven torpedoes
were fired scoring one hit. It was then decided that the patrol vessels
were of such shallow draft that the torpedoes were running under their
target except for one lucky one which probably ran shallow. At this
time the BRILL was inside the 10 fathom curve and since it was too dark
to use deck guns she broke off the attack.

On 19 July, while operating with other U.S. submarines, contact was
made with a small convoy, consisting of two merchantmen, a Kamikaze class
destroyer and two small patrol vessels. After fuggling for position each
submarine in turn made an attack and the BRILL made the second attack
about 2140 firing 4 torpedoes at the destroyer. No hits were scored
and no counter attack was made by the escorts, although the escorts were
heard searching.

At this time six torpedoes were heard running from another submarine
attack. At 0400, 20 July, since there was not enough time left for
another attack before dawn, the BRILL broke off and departed the area. On
24 July, two Siamese natives were taken aboard from a raft constructed
of three oil drums lashed together. One of the natives spoke English
and according to him they had been adrift for five days. After a bath
and food they appeared to be in good condition. For the duration of the
patrol no ship contacts worthy of note were made. Several sailing junks
were boarded and the cargo of about five tons of sugar carried by one
of these vessels was jettisonned. This junk was bound from Khot Baru
to Singora. They tried to enter Singora, but were prevented by bombing
and were returning to Khotz Baru.

On 1 August, 1945 the BRILL made rendezvous with the CHUB to give
her 5"/25 ammunition. The sea was rough and transfer was attempted by
rubber boat. After two trips the CHUB's boat sprang a leak and no fur-
ther transfer was made. On 2 August the BRILL set course through the
Java Sea and headed for Lombok Strait. On 3 August she made transit of
Lombok Strait, arriving in Fremantle on 9 August, to conclude her third
patrol before the war ended. On this patrol a total of 9,778 miles was
steamed and 117,420 gallons of fuel consumed. A total of 42 days was
spent at sea including 23 days in patrol area.

In Fremantle, a patrol refit was conducted by Submarine Division 302
on the U.S.S. CLYDE (AS 26). After completion of this refit on 22
August, 1945 Lieutenant Commander R. W. Alexander, U.S. Navy, relieved
Commander H. P. Dodge, U. S. Navy, of command. On 31 August, 1945 the
BRILL in company with the U.S.S. BUFFER, U.S.S. BURRA U.S.S. CHUB departed
Fremantle, for Subic Bay, Arrived in Subic Bay on 9 September, 1945.

The BRILL has been assigned to the active Pacific Fleet.

1. In accordance with the provisions of reference (a) and (b)
Addendum to the Ship's History of this vessel is submitted:

"The ship spent from January 27 to February 5, 1946 in Pearl
Harbor while the Base tried to repair our motors. At the end of this time
they decided to wait for our scheduled overhaul, and sent us to San Diego
on three motors, the fourth being detached electrically. They moved our
navy yard availability date from June 15 to May 1, 1946.

February fifth a jubilant BRILL again headed east. The
remainder of the trip was uneventful. Steaming alone was a pleasant relief.
Early the morning of February twelfth (fourteen months since departing from
New London) we tied up in nest alongside U.S.S. SPERRY (AS-12) at San Diego
California. A few hours later fifty percent of the crew was streaming ashore
for thirty days annual leave. The remaining fifty percent settled down to a
routine of upkeep and liberty.

Personnel has proved our major problem during this rehabili-
tation and leave period. We transferred one officer, Lieutenant (junior grade)
W.R. Miller, D-V(S), USNR, and forty one men to release from active duty. The
Chief of the Boat, J. Poltz, CTM (SS), Fleet Naval Reserve, was transferred
to Mare Island for further assignment and Alex DiCicco, MOMM (SS), U.S. Navy,
took over. On the black side of the ledger we have received since our
arrival, two officers and twenty seven men, but personnel will continue to
be a major problem for several months.

(C) WEATHER
The weather in Tonkin Gulf was almost continually overcast and
occasionally foggy as described in the Coast Pilot.

(D) TIDAL INFORMATION
Currents were influenced greatly by the weather but the following
generally prevailed:
At the southeast coast of Hainan and south to 17-00N the set is
from south southwest to southwest and the drift .2-.5 knots. South of
17-00N the current bends to the southeast and parallels the Indo China
Coast with a drift of .5-1.0 knots. West of 108-00E and along the south-
west coast of Hainan the currents were weak and variable generally being
of about .2 knots.

(E) NAVIGATION AIDS
None were sighted.
The unsounded part of Tonkin Gulf between Tourane and Hainan was
thoroughly covered and the least sounding obtained was 46 fathoms and
the greatest 52 fathoms.

The following soundings are located with fair accuracy:

16-51.5 N           51 fathoms           17-14.5 N           47 fathoms

Numerous junks and fishing sampans were sighted in the Tonkin Gulf area.

(G) AIRCRAFT CONTACTS

There were a total of 27 aircraft contacts in the Tonkin Gulf area.
Of these 14 were SD radar contacts which were not sighted. Of the air-
craft sighted two were single float seaplanes and two were dive or torpedo
bombers acting as convoy escorts. The remainder of the aircraft sighted
were medium bombers, some of which were probably our own. One attack was
made by aircraft during the course of which three bombs were dropped.
This contact was by radar alone at 5 miles. Three night dives were made
for close radar contacts.

(H) ATTACK DATA

No attacks made.

(I) MINES

A total of 5 drifting mines were sighted. One was detonated by 20 MM
gun fire. One was detonated by .30 caliber machine gun fire. Two were sunk
without detonating by .30 cal. machine gun fire. On the remaining occasion
the ship was forced to dive before the mine could be destroyed and it
was not located again. Three of the mines were sighted in positions such
as to indicate that they had broken adrift from the Yulinkan minefield.
The position of the other two would indicate that they had probably
drifted down Tonkin Gulf to the westward of Hainan.

No mine laying or mine sweeping operations were observed.

(J) ANTISUBMARINE MEASURES AND EVASION TACTICS

On the one occasion that this vessel was attacked by aircraft two
bombs were dropped during submergence. Several minutes later a single depth
charge was dropped which showed on the depth charge indicator as starboard,
aft and below.

The keel depth at that time was 120 feet.

Torpedo wakes were sighted on two occasions. On the second occasion
three wakes were reported by lookouts but only one was identified to
the satisfaction of the Commanding Officer.

(K) MAJOR DEFECTS AND DAMAGE

Hull and Machinery:

1. Cylinder Head Studs:-

During the patrol a total of 12 cylinder head studs were broken
and replaced by the ships force. Nine studs were replaced on #4 main engine
and one stud each on #1 and #3 main engines. General Motors Model 278.

Before starting our patrol, all studs on each main engine were
checked at a torque of 650 lbs-feet, the pressure recommended by the manu-
facturer. The studs on #4 main engine were again checked at this pressure on
February 7, 1945, after two studs had been broken. During this check, it was
discovered that the pressure on some studs reached as high as 725 lbs-feet,
while on others it had dropped to the neighborhood of 575-600 lbs.-feet. As
the troubles persisted - three more studs being found broken - all the studs
on #4 main engine were slacked off and re-torqued to 650 lbs-feet on February
18. This operation seems to remedy the troubles temporarily for no more broken
studs were experienced until March 4, 1945, when two more studs on #4 main
engine were found broken and replaced. The troubles continued through March
22, when one broken stud on #4 main engine was replaced. No further troubles
was experienced during the return trip to port after the replacement of this
stud.

As most of the studs found broken were on #4 main engine, it may
be possible that faulty studs were installed at the factory. In any event,
the head studs on all main engines will be thoroughly checked and re-torqued
during the refit to attempt to remedy this grave defect.

(K) MAJOR DEFECTS AND DAMAGE (CONT'D)

2. Cylinder Liners:

During the patrol the following cylinder liners were replaced:

No. One Main Engine - No. 12 unit and No. 13 unit replaced
6 February, 1945.
No. Two Main Engine - No. 3 unit and No. 6 unit replaced
13 February, 1945. No. 6 unit replaced
again on March 23, 1945, after 107
hours in use.

Upon inspection, there was no visual indication of cracks in the
liners taken from #1 main engine. The loss of engine cooling water, which led
to replacement of the liners being cracked, was no longer evident after replace-
ment. The loss of cooling water may have been caused by leaky rubber grommets
on both units.

No. 13 unit liner of #2 main engine showed a visible crack around
one of the liner stud holes. The stud concerned was measured and found to be
0.001 inches over size, which may have been the cause of the cracks. Additional
spare liner studs were measured and out of the total of twenty-four carried
as spares, it was found that three studs were each 0.001 inches over-size.

No. 6 unit liner of #2 main engine was replaced twice during the
patrol. Each time, there was no visual indication of a liner crack, the loss
of cooling water may again have been due to leaky grommets.

When preparing one spare liner for replacement it was cracked while
inserting one of the studs. The stud was checked with the standard 5/8" die
before inserting it; but never-the-less the liner cracked around the hole when
the stud was approximately three quarters of the way home. It is believed that
the design weakness of the liner around the stud holes was the main cause of
most of the liner trouble.

It is intended to have four liners, which showed no visible cracks,
pressure tested during the refit period to determine if they are suitable for
further use.

3. Injectors:

Three main engine unit injectors were replaced, and subsequently
repaired, by the ships force. In every case, it was found the injector failure
was caused by the disintegration of the porous bronze fuel oil filter which
caused a seizure of the push rod or leaking of spherical check valve. If
possible, the bronze filters will be replaced by stacked washers during the
coming refit period to prevent similar failures in the future.

4. Bow Buoyancy Vent has repeatedly failed to close hydraulically
but never failed to open. This first occurred in New London where E.B. Co.,
worked on the vent operating valve in the control room. Pearl Harbor checked
the alignment of the shafting, realigned the stuffing gland on the after
bulkhead of bow buoyancy, and refitted the screen around the after vent flapper-
valve. At Saipan the shafting was again checked for alignment and proper operation.
After each of the above overhauls, the vent operated properly for a short
time.

The exact cause for this difficulty has not yet been determined.
Another complete check of the system will be made during the refit.

ORDNANCE AND GUNNERY

No major defects.

(L) RADIO

Transmissions:

5 February - Called Saipan on 4155 and 6310 Kcs several times with no
response. Called WQO (any shore station) on 4235 Kc. NPG and
NGK answered. Gave NGK the message receiving proper authen-
tication. NPM rogered on Sub Fox.

17 February - Called VIXØ several times on 4235 Kcs and then sent message
blind. Heard VIXØ strength one asking for repeats. An un-
known ship station interposed, and worked VIXØ for us. Sent
repeats and received roger on VIXØ fox schedule.

20 March - Called VIXO on 4235 Kcs and delivered message with no
difficulty.

26 March - Same.

Casualties:

15 March - TBL-12 failed to operate. Trouble was quickly traced to 860
tube in H.F. master oscillator. Tube was replaced and normal
operation resumed.

For a period of two (2) days (7 March to 9 March) radio
communication with the CHUB (SS329) failed. Signals from
other friendly submarines were clearly audible on the area
frequency during this time. The antenna proved to have zero
resistance to ground. Hand hole plates were removed from
the lead-in trunk to check for flooding and was found dry.
Power output on the antennas was checked and all three were
found to be radiating. The insulators were checked for
fouling or cracks. Normal communication was resumed seven
hours later, although no explanation can be given.

(L) RADIO (CONT'D)
Comments:
The AN/BEC-4 V.H.F. transceiver was used only during lifeguard operations.
Only one transmission was heard and that was unintelligible. No
transmissions were attempted.

The KDS radio receiver proved in-dis-pensible for the VIXØ for schedule,
as the RIL-7 was most satisfactory while in patrol area.

(M) RADAR
1. SD-5 Radar.

The SD-5 radar equipment, with the exception of a few minor casualties,
all tube failures, was in excellent operating condition for the duration
of the patrol.

2. SJ-1 Radar.

The SJ-1 radar equipment was an unending source of trouble from the
time of entrance into the patrol area until the present date. It was and
is in relatively poor operating condition judging from the performance
obtained prior to entering the patrol area. The personnel assigned the
task of maintaining the radar equipment have left no stone unturned to
get at the seat of the trouble but have been unable to do so. In fact,
they are to be commended for returning the SJ-1 equipment to its present
state, even though it is still below normal.

The troubles started when the magnetron which was in use began to
double mode and cause a high standing wave ratio to be set up in the
waveguide. The magnetron had been in use since commissioning and had
about 770 filament hours, so its failure was nothing to be alarmed about.
However, when this magnetron was replaced with another (No. 23729), it
arced internally. This was found to be caused by a grounded filament.

All tubes in the modulation generator of the transmitter and the
modulation network have been replaced. R36, a fusing resistor was found
to have been burned out by the arcing.

Trouble still exists in the SJ-1 transmitter but, with the equipment
aboard and the space facilities, it has been impossible to isolate.

Another trouble which occurred was the continual failure of the A and
B regulated rectifiers.

-25-

ENCLOSURE (A)

— page 33 —
(M) RADAR (CONT'D)
It was found that the whole trouble was due to faulty installation.

Several connections in the junction box located in the conning tower
were very poorly made and were intermittent open circuits. This put a
load on the regulated rectifiers that caused the poor rectifier tubes to
fail much too often. This condition was remedied by repairing the
faulty connections and operation has been normal since the repairs were
effected.

3. ST Radar

Except for occasional tuning difficulty the ST radar equipment was
in normal condition for the duration of the patrol.

4. APR-1 and SPA-1 Radar Detection equipment.

The APR-1 search receiver turned in very disappointing results for
the duration of the patrol. No checks could be made on its operation
due to lack of test equipment. The poor results obtained are probably
due to poor installation and inexperienced operating personnel. The SP-1
pulse analyzer was useful as a tuning indicator for the ST radar equip-
ment.

There were so many internal noises present which were indicated by
the APR-1 that it was quite difficult to pick up external signals.
Better shielding of leads is suggested as a remedy for this difficulty.

(N) SONAR GEAR AND CONDITIONS

Contacts:

1 March - After initial contact by radar three patrol boats were picked
up at a range of 8,000 yards and tracked in. Echo ranging was
heard at 17 Kcs. Submarine was submerged to 90 feet in is-
othermal water. Position - Lat. 18°-21' S. Long. 108°-35' E.
Time - 2100 G.

5 March -, A large tanker was detected at 12,000 yards by JP sound gear.
JK and QC supersonic gear detected the target at 10,000 yards
and two escorts at 9,000 yards. A temperature drop of 4° (72-68)
degrees existed between depths of 30 and 50 feet. Position -
Lat. 18°-24' N. Long. 110°-13' E. Time: 1100 G.

25 March - JP detected the sound of breakers on the beach of Sakala
Island at 7,000 yards. The sea was dead calm with glassy
surface. No density layers were present. Position - Lat.
06°-35' N. Long. 116°-18' E. Time: 1200 H.

(O) DENSITY LAYERS

While in the patrol area, a total of eight major density layers
were experienced, as follows:

Date        Lat.        Long.       Type        Feel Depth
                                    Gradient
3/3/45      17-31       109-01      2° Negative 65-125'
3/4/45      17-41       109-57      6° Negative 65-155'
3/4/45      17-42       109-57      7° Negative 45-145'
3/4/45      17-42       109-57      2° Negative 65-95'
3/5/45      18-19       110-04      5° Negative 40-65'
3/10/45     16-32       108-24      Isothermal  0-135'
3/14/45     17-53       110-05      3° Negative 85-130'
3/17/45     18-11       108-15      3° Negative 45-105'

The general shallowness of the water throughout the area was
probably responsible for the isothermal water encountered in most all
cases.

Because of the lack of contacts, the Bathythermograph was not used
in conjunction with the sound gear for sound range predictions.

(U) COMMUNICATIONS, RADAR, AND SONAR COUNTER-MEASURES
Communications Countermeasures:

Enemy interference was present on all frequencies, both tactical
and administrative. No deception during ship shore or ship-ship trans-
missions was noticed. On several occasions evidence of a monitoring
receiver was shown by increased jamming coincident with transmissions
by boats on area frequency.

Subject: U.S.S. BRILL (SS330) - Report of First War Patrol.

1. The first war patrol of the U.S.S. BRILL under the command of
Commander H. B. DODGE, U. S. Navy, was conducted between the Indo China coast
and Hainan. Patrol was of 60 days duration of which 29 days were spent on
station.

2. Only one contact worthy of torpedoes was made during the entire
time in the area. This one contact was a large tanker escorted by 2 DE's, with
two single engine dive or torpedo bombers as air cover. Initial range 12,000
yards, angle on bow 80 starboard, speed 14-15 knots. This target could not be
closed. The closest range reached was 7,100 yards. About ten hours later a
properly marked hospital ship was contacted on an easterly course speed 15 knots.

3. On 20 February two torpedoes were fired at BRILL from a submerged
submarine, both passed down starboard side. Again on 15 March in the same vicin-
ity a torpedo missed 100 yards astern. In both instances BRILL cleared area,
dove and returned to vicinity but no contact was ever gained with the enemy sub-
marine.

4. On 21-25 March, BRILL conducted a special mission which was
successfully completed.

5. The BRILL on arrival from patrol was clean and ship-shape. Refit
will be completed in normal time. Morale is high as evidenced by the attitude
of the officers and crew.

6. The Squadron Commander welcomes BRILL to this area and congratu-
lates the officers and crew upon the completion of their first war patrol. It
is regretted that no damage was inflicted upon the enemy.

1. The First War Patrol of the BRILL, under the command
of Commander H. B. DODGE, U.S.N., was conducted in the areas of
the SOUTH CHINA SEA between the INDO-CHINA coast and HAINAN ISLAND,
and in the approaches to TONKIN GULF.

2. No contacts which were worthy of torpedo fire could
be closed. A single contact on a large tanker was observed to
pass at a minimum range of 7,100 yards. On two occasions the enemy
fired torpedoes at BRILL, and in each case effective evasive action
by BRILL was followed by an aggressive attempt to locate the enemy
submarine in order to launch a counter attack.

3. On 25 March, BRILL conducted a Special Mission which
is covered by a special report.

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

5. The Force Commander congratulates the veteran Command-

(L) RADIO
    TBL-12. Prior to departure on patrol, trouble developed while calib-
    rating frequencies to be used in patrol area. After four days of constant
    work by relief crew technicians, the condition was improved slightly.
[HANDWRITTEN: BUSHIPS]
    It was noted by the ships force that the master oscillator plate cur-
    rent was abnormally low and that under certain operating conditions no zero
    beat point could be determined when tuning to standard frequency due to
    parasitic oscillations. (Noted on Bands 2,3,4 and 7, high frequency master
    oscillator).
    Frequencies set by dial readings as calibrated before leaving for area,
    were satisfactory. Trouble was experienced in loading the antenna. On 15
    May, after tuning to give a maximum antenna current of seven amperes, the
    transmitter was secured upon completion of a transmission. Eight minutes
    later, the current had dropped to five amperes and signal strength (Cobia)
    from 3-4 to 0 to 1. Further tuning did not help. Atmospheres were very
    heavy and the three boats called (HAWKBILL, COBIA and BESUGO) were heard
    with difficulty; BESUGO best at strength 2 to 3. Ten hours were spent in
    clearing the message to those addressees.
    RAL - Used almost entirely for BAKERS Fox schedule.

            cuit. No transmissions or receptions on the latter.

      function.

   B. No high voltage in pulse analyzer.

   C. Brightness control inoperative.

[HANDWRITTEN: 3-XRA]

-12- CAUSE AND REMEDY

B. Intermittent sync voltage due to
   bad connection in cable from
   selector unit to rango unit. Re-
   paired cable and operation re-
   turned to normal.

C. Modulation network case was as-
   sumed to be punctured since it
   was covorod with oil. Network
   was replaced and operation re-
   turned to normal. Total time
   equipment was out of commission -
   four hours.

D. 5U4G tube in cach rectifier bad.
   Replaced tubes and fuse and op-
   eration returned to normal.

E. Checked tubes in modulation
   generator, replaced an 807 which
   tested low. Took waveforms and
   voltage and resistanco checks,
   found base multivibrator to be
   functioning improperly. Replaced
   VR 150-30's and inaggie output
   returned to normal. Double sweep
   on A scope. Adjustment of "on
   time" and "coarse repetition
   rate" corrected sweep.

CAUSE AND REMEDY

A. Horizontal centering potentio-
   meter was burned out. Replaced
   and operation returned to normal.

B. Open winding in power trans-
   former high voltage secondary.
   Transformer replaced and oper-
   ation returned to normal.

C. Mechanical linkage between knob
   on front panel and potentiometer
   broken. Makeshift repairs woro
   effected and operation returned

By the use of the RBS and RAL and all the frequencies, VIXO could usually
be copied.

2. Jamming - See above.

3. Deception -

20 May an unknown station interfered with communications on area
frequency. The signals were loud and clear and there was evidence of the use
of a monitoring receiver. The signals sent consisted of unrelated characters
that were probably thought to confuse the boats transmitting then. Such
procedure signs as AR, K, AA, etc., were sent, but apparently the sender had
no idea of their use.

the last day on station did the BRILL stay on the surface in order to contact
our Navy search planes. This was most unfortunate as several worthwhile con-

but unsuccessfully, to report these contacts direct to the BRILL on the sub-
marine area frequency. One aircraft contact report was relayed via CTF 71 to
the BRILL, but arrived twenty-four (24) hours late, and was garbled due to the

1. The Second War Patrol of the BRILL under the command
of Commander H. B. DODGE, USN, was spent off the East Coast of MALAYA.
There were no contacts with nor any damage inflicted on the enemy.

2. Considering that no known enemy air contacts were made
and that our own search planes were searching this area daily and
attempting to communicate with BRILL too much time was spent sub-
merged to cover this area thoroughly and effectively.

3. The award of the Submarine Combat Insignia is not

          as a Kamikaze class destroyer and he became the target. The
          range at that time was 5000 yards, large starboard angle on the
          bow.
2142 G Commenced firing salvo of 4 torpedoes from bow tubes. Target
          course 305, speed 12 knots, track angle 75 starboard, gyro angle
          000, torpedo run 2900 yards, firing interval 8 seconds, depth
          6 feet. Spread by periscope 2 at MOT, 1 at bow, 1 at stern.
          Two minutes after firing the target turned toward and all tor-
          pedoes missed.

          No counterattack developed although three escorts were heard
          searching.
2316 G Surfaced.
2318 G Radar contact and SJ interference at 075° T, range 11000 yards.
          This was determined to be BUMPER and fell in astern of her.
          Convoy at 060° T, range 21000 yards.

          mission.
0205 G COD reported unable to affect repairs to radar and breaking off
          attack.
0410 G BUMPER reported all torpedoes expended.
          There was not enough time left for end around before dawn and
          sounding showed 14 fathoms. Broke off tracking and sent out mes-
          sage informing other boats that we were departing area.

and 45° starboard. Decided that target, a Kamikaze class destroyer
was constant helming on a base course 000°. We were about on
the track and hoped to get a stern tube shot with high speed tor-
pedoes.
0729 G Target has been on a steady course for two minutes. Realized
that he was not running a constant helm but a snap zig of about
3 minute legs. Range 1400 yds, speed 20 knots, only a zig to-
ward would give us a shot. Started coming left to bring bow
tubes to bear.
0730 G Target took a big zig left leaving us with a large angle 170°
track shot which was not considered possible.

(G) AIRCRAFT CONTACTS
A total of 8 aircraft contacts were made during this patrol.
3 of the contacts were by SD radar only. They were quite close and
no IFF response was obtained so dove.

Of the 5 visual contacts one was a PRIVATEER which circled the ship
and one passed out of sight at long range unidentified. The remainder
was a flight of three aircraft sighted at too great a range to be identi-
fied. There was no IFF response from this group and they were believed
to be enemy.

No pertinent information.

(J) ANTISUBMARINE MEASURES AND EVASION TACTICS

No antisubmarine measures were encountered other than echo-ranging
by convoy escorts. No counterattacks developed after any of our four at-
tacks. Ran silent after the night submerged attack on 19 July. The boat
was slightly heavy after the attack, and settled to 90 feet during sound
search by escorts. At times it seemed that they must have contact but no
attacks developed.

Regained periscope depth as soon as it was felt to be feasible to use
speed. Nearest escort was at 4000 yards. Cleared at periscope depth.

FIRST ENDORSEMENT to
USS BRILL (SS330) -
Report of Third War
Patrol.

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

Subject: U.S.S. BRILL (SS330) - Report of Third War Patrol.

      1. The third patrol of the BRILL under the command of Commander
H. B. DODGE, U.S. Navy, was conducted in the Gulf of Siam. Patrol was of
thirty seven days duration with twenty three days being spent in the area.
From 17-19 July the Commanding Officer of the BRILL was O.T.C. of an attack
group consisting of DUGARA, BUMPER and SUPREME.

      2. Torpedo attack No. one. On 11 July the remnants of a convoy,
previously attacked by HAILERHEAD, was contacted and attacked. This was a
night surface radar attack on one unidentified ship and one escort. On first
approach four Mk-14 torpedoes were fired from stern tubes on a 95° starboard
track, small gyro angles, depth set six feet, with a torpedo run of 3000
yards. All torpedoes missed. On second approach, 30 minutes later, four
Mk-18 torpedoes were fired from bow tubes, on a 95° starboard track, gyro
angle 35° R, depth set six feet with a torpedo run of 2500 yards. One hit
was obtained and target remained stopped for 15 minutes and then went ahead
at 3 knots. On third approach, fifty minutes later, three Mk-18 torpedoes
were fired from bow tubes on a 110° starboard track, small gyro angles,
depth set 4 feet, with a torpedo run of 2100 yards. All torpedoes missed.
At the conclusion of this attack the BRILL was inside the 10 fathom curve,
and as it was too dark for a gun action no further attacks were made.

      Torpedo Attack No. Two, was a night submerged attack using
ST radar on a convoy consisting of three small cargo vessels escorted by 3
small escorts and one Kamikaze Destroyer. The Kamikaze Destroyer was selected
as the target and four Mk-18 torpedoes were fired from bow tubes on a 75°
starboard track, zero gyro angle, depth set six feet, with a torpedo run of
2900 yards. Two minutes after firing target turned towards and all torp-
edoes missed.

      3. On 28 July a Kamikaze Destroyer was contacted which was making
20 knots and zigging every three minutes. Stern tubes were brought to bear
so that Mk-14 torpedoes could be fired. A very favorable attack position
was reached with a range of 1400 yards and a 75° starboard track. The BRILL
did not fire though the target still had at least a minute more on this leg of zig.

A16-3, serial 27, (no
date), Report of Third
War Patrol.

From: The Commander Submarines SEVENTH FLEET.
To: The Commander in Chief, UNITED STATES FLEET.
Via: The Commander SEVENTH FLEET.

Subject: U.S.S. BRILL (SS330) - Report of Third War Patrol -
(3 July to 9 August, 1945).

1. The Third War Patrol of the BRILL under the command
of Commander H. B. DODGE, U.S.N., was conducted in the GULF of SIAM.

2. Three night surface attacks were made on two small
unidentified ships believed to be the escorts and remnants of a con-
voy previously attacked by the HAMMERHEAD. Eleven torpedoes were
fired and one hit was heard on the second attack. That damage was
inflicted is evidenced by the fact that the target stopped for
fifteen minutes and then proceeded at about half his former speed.
The second opportunity for attack was on a KAMIKAZI destroyer es-
corting a convoy. Four torpedoes were fired in a night submerged
attack and all missed because the target turned toward. A second
opportunity to sink this troublesome KAMIKAZI was presented a few
days later when the submerged BRILL maneuvered into a favorable
attack position but waited too long to shoot and the destroyer
zigged away.

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

4. The Force Commander compliments the BRILL on the safe
completion of this patrol and regrets that more damage was not in-
flicted on the enemy. The following damage is assessed:

DAMAGED

1 - Unident 1,000 Tons.
