Cachalot

The sperm whale.
*Cachalot* (SS-33) was renamed K-2 (q. v.) on 17 No-
vember 1911 prior to her commissioning.

17 k.; cpl 43; a. 1 3", 6 21" tt.; cl. *Cachalot*)

*Cachalot* (SS-170) was launched 19 October 1933 as
V-8 (SC-4) by Portsmouth Navy Yard; sponsored by
Miss K. D. Kempff; and commissioned 1 December 1933,
Lieutenant Commander M. M. Kimmel in command.
After shakedown, further construction, tests, and
overhaul, *Cachalot* sailed for San Diego, Calif., where on
17 October 1934 she joined the Submarine Force, U.S.
Fleet. Operating until 1937 principally on the west
coast, she engaged in fleet problems, torpedo practice,
antisubmarine, tactical, and sound training exercises.
She cruised twice to Hawaiian waters and once to the
Canal Zone to participate in large-scale fleet exercises.
*Cachalot* cleared San Diego 15 June 1937, bound for
New London, Conn., and duty in an experimental torpedo
firing for the Newport Torpedo Station, and sound train-
ing for the New London Submarine School until 26
October 1937 when she began a lengthy overhaul at
New York Navy Yard. A year later she sailed for par-
ticipation in a fleet problem, torpedo practice and sound
training in the Caribbean and off the Canal Zone, and
on 16 June 1939, reported at Pearl Harbor for duty with
the Submarine Force and the Scouting Force.
War came to *Cachalot* as she lay in Pearl Harbor
Navy Yard in overhaul. In the Japanese attack of 7
December 1941, one of her men was wounded, but the
submarine suffered no damage. The Yard work on her was
completed at a furious pace, and on 12 January 1942
she sailed on her first war patrol. Fueling at Midway on the
way, she conducted a reconnaissance of Wake, Eniwetok,
Ponape, Truk, Namonuito, and Hall Islands, returning
to Pearl Harbor 18 March with vitally needed intelli-
gence of Japanese bases. Her second war patrol, for
which she cleared from Midway on 9 June, was con-
ducted off the Japanese home islands, where she dam-
aged an enemy tanker. Returning to Pearl Harbor 26
July, she cleared on her final war patrol 23 September,
penetrating the frigid waters of the Bering Sea in sup-
port of the Aleutians operations.
Overage for strenuous war patrols, *Cachalot* still had
a key role to play during the remainder of the war,
which she spent as training ship for the Submarine
School at New London. She served here until 30 June
1945, when she sailed to Philadelphia where she was
decommissioned 17 October 1945. She was sold 26 Janu-
ary 1947.
*Cachalot* received three battle stars for World War II
service.

1. This patrol is the longest that a submarine of
this force has been away from its base, and it is gratifying
to note that health and morale of the personnel were excellent
upon return to the base.

2. Remarks on previous patrols concerning surface
cruising to and from station, apply equally to this patrol.
Too much time was consumed to and from station because of
cruising submerged during daylight, resulting in a reduction
in the days on station.

3. After the attack on February 24, 1942, the
CACHALOT should have remained at periscope depth to observe
results of the attack particularly on a damaged ship if she
served. Positive evidence of sinking must be had or an
attempt made to push home an attack on a damaged ship if she
is not seen to be sinking. Further, had CACHALOT remained
at periscope depth, the source of fast screw noises be-
lieved to be destroyers could have been observed with the
possibility of attacking.

4. Due to lack of evidence, no damage to the
enemy is credited CACHALOT, although there is a possibility [STAMP: RECEIVED S-C FILES]
that one torpedo hit was made. [STAMP: Room 2055]

Subject: U.S.S. CACHALOT War Patrol, Comments on.

1. The bombing of the CACHALOT is of particular
interest in that this is the first known instance in which
the Japanese have made a night air attack on any ship. It
emphasizes the importance of equipping all submarines with
radar at the earliest opportunity. It is probable that the
submarine was detected by means of its wake as it was making
9 knots when sighted. The fact that the plane was showing
running lights might indicate that a simultaneous search was
being conducted by several aircraft.

2. Although conclusive evidence is lacking it appears
probable that the enemy ship was sunk by the attack on February
24, 1942 as otherwise it should still have been visible after
coming to periscope depth thirty minutes later.

3. The report shows that 8441 miles were covered with
a fuel expenditure of 56760 gallons, indicating that about
23000 gallons remained after returning to port, exclusive of the
12,000 gallons obtained at Midway. This demonstrates the unusual-
ly high cruising radius of both the CACHALOT and its sister ship.
This ship was away for 66 days which is the longest period that
any submarine has yet been away from its base. The health and
morale of the crew were excellent upon return although the patrol
was conducted under many difficulties. This reflects greatly
to the credit of the Commanding Officer. It is unfortunate that
more opportunities for attacking the enemy did not occur due to
scarcity of shipping in the areas patrolled.

Subject: U.S.S. CACHALOT - Second War Patrol, Comments on.

1. CACHALOT returned from patrol in good material
condition and with her crew in exceptionally good health and
spirits.

2. Discounting small craft, only two contacts were
made. Previous experience indicates that similar poor results
may be expected unless the submarine patrols in the immediate
vicinity of the shore where the vast majority of enemy ships
are routed. This known fact was not utilized by CACHALOT as a
study of the track chart reveals she spent the majority of her
patrol well clear of the coast.

3. Results of the one attack are disappointing.
After firing one torpedo and registering a direct hit on an
unescorted 9,200 ton tanker, CACHALOT allowed the enemy to take
the inititive, went to 250 feet and made no further attempt to
return to periscope depth where the crippled tanker might well
have been sunk. A more determined and aggressive attack would
undoubtedly have resulted in the loss of a valuable ship to
the enemy.

Subject: U.S.S. CACHALOT War Patrol - Comments on.

1. The results obtained by CACHALOT on this patrol
are disappointing. The vessel was in the area approximately twen
one days. In addition to small craft only two contacts were
made. One of these was attacked with doubtful results, although
one hit was made.

2. It is appreciated that luck enters into the numbe
of contacts made when a submarine is operating in a large area.
When, however, contacts were not made during the first few days
in the area, the Commanding Officer should have searched the ship
lanes near the shore lines where past experience and his instructi
indicated traffic might be expected.

3. The material condition of the CACHALOT shows a
decided improvement over the condition upon returning from the
previous patrol. It is noted that there were no failures of the
trim, drain and compensating lines. These lines were completely
renewed by the Submarine Base in a period of three weeks just
prior to this patrol. This indicates the high quality of work
accomplished by the Submarine Base when the Navy Yard estimate
for the same job was six weeks.

4. This patrol was not aggressively conducted. One
torpedo was fired at a tanker and observed to hit. The tanker
then appeared to take the initiative, the CACHALOT going to deep
submergence where she remained for five hours and ten minutes.
This tactic is inexplicable to the Squadron Commander.

              1. Although the CHOPLOT evidenced an aggressive
spirit on this patrol, no positive results were obtained.

              2. The remarks of Commander Task Group Eight Point
Five in enclosure (A) are concurred in. The presence of a sub-
marine on station, even when no positive results are obtained,
still has considerable strategic value. The enemy is forced to
zig-zag and use uneconomical speeds, to lengthen his
lines of communications by routing his ships along indirect
tracks, to maintain constant vigilance and to suffer a constant
mental hazard. On this particular patrol, as stated in paragraph
four of enclosure (A), the CHOPLOT indirectly, by her presence
alone, assisted in the destruction of two enemy destroyers.

              3. Because of the lack of any positive evidence of
a hit, the CHOPLOT is not credited with having inflicted any
damage on the enemy in the attack. As there has been no
opportunity to interrogate the commanding officer regarding the
time the explosions heard were torpedoes exploding at the end of
the run.

Subject: U.S.S. CACHALOT - Report of Third War Patrol.

Enclosure: (A) Original and one copy of subject report.

1. The assigned area was covered in a thorough
manner. That contact with the enemy was made on two
occasions is disappointing, particularly in view of the poten-
tialities of the SJ radar for night search. The scarcity of
contacts was due in a large measure to enemy activity in the
ALEUTIANS reaching a minimum during the thirty-one day period
the CACHALOT spent on station.

2. One contact did not present an attack oppor-
tunity. On the other occasion, on October 10, the CACHALOT,
after developing two radar contacts in darkness in the con-
fined waters of VEGA BAY, and after firing at the first target,
found herself hemmed in by destroyers, one ahead and one astern.
The initiative was maintained as long as was reasonably possible.
It is notable that, against the mountainous land background,
no radar contact, and tracking down to no sight range, was accomplished.
While the failure to detect the destroyers by radar may have been
due to their presenting a smaller target, it was more probably
due to concentration on the tracking of targets already detected.
The use of the SJ radar in darkness is, of course, analogous to
the use of the periscope in daylight and hence during an attack
should include periodic, but thorough, sweeps to avoid being
surprised by escorts.

3. The Commanding Officer reports in the narrative
that both torpedoes fired at the freighter missed ahead, while
in the action report he estimates the possibility of one hit.
He is not available for questioning on this divergence in the
report, nor for ascertaining the estimated speed of the target,
which is not listed. From the fact that the target had been
tracked at slow speed and was seen to back and turn towards, the
belief is expressed that both torpedoes did miss ahead. It is
quite possible that the CACHALOT was sighted prior to firing.
The firing of the third torpedo, at a destroyer ahead, while the
submarine was backing and swinging with full rudder to avoid an
enemy torpedo coming up astern, is considered to have been fully
