of the SEAHORSE is fair. ALl engines are definitely in need of a major overhaul.
The SEAHORSE WILL enter the yard for regular overhaul.

Commander Officer, officials and men of the SEAHORSE for another aggressive,

exceedingly well conducted and successful war patrol. The Commanding Officer
of the SEAHORSE is further congratulated for the extremely efficient manner in ,
which he controlled the offensive-reconnnaissance group during the PALAU 'T'andings,
The sinking of an enemy destroyer at this time rendered a severe blow to the enemy
in one of its weakest spots. '' ' .

         4525 Kcs. Not a good signal because of exces-
                           sive interference and very noisy
                      most of the time.
        9090 Kcs. Reception was generally good with
                         fading between the hours of 1800 to
                   2000 zebra. Some enemy interference
                      was noted on the l100 zebra schedule.
                      The 1300 and 1600 zebra schedule was
                      generally good without interference.
         14390 Kcs. Pood signal with fading in late
                          afternoon.
       The following tabulation is given on the new HAIKU frequencies:
         4515 Ks. Noisy but with a strong signal at
                      night with considerable interference.
                          Can be copied with some difficulty
                          at night but not receivable in
                        daytime.
         6045 Kcs. Pood reception at night with fading
                        and interference during daylight
                        hours.
         9515 Kcs. Good durning hours of darkness and
                          late afternoon with much interfer-
                          ence between 1800 to 2000 zebra.
         16730 Kcs. Especially good durning morning day-
                        light hours but fading towards night.
      All of ComSubSep serials W'e received. numerous transmissions
      were made botb to CombSap传达, to members of the Zoo and to the
     Wolf pack. Little d'ifficulty was experienced in any of these
     transmissions except the u~sual trouble found when trying to raise
     shore statiows durking daylight hours. Enemy jamming of d rtrans-
     missions was not experienced on this patrol.
     Of the four Wolf Pack frequencies assiqned, 2102 kcs. and 2204
     kcs. were f ound to be satisfactory. interference was encountered
     on- 2006 Kcs. and 21 60 Kcs. which was due to some of our own
     forces using these frequencies for voice transmissions. It is
     suggested that these frequencies be replaced by others in the
     2000 kcs. band to eliminate this interference. The secondary
     or low frequency was not utilised at any tim e on this pack
     operation.
     Excessive tuning of the transmitters of various m nbers of our
     submarine force in the area was noted. Tuning of the transmitl4 ers
       of all members of the pack before leaving port cannot be too -

                  - Report of Sixth War Patrol.
              to us with promptness. However, it is considered
              a matter of sufficient importance to note that we
              received the contact report 7 hours and 35 min
              uites after the contact was made something less
              than 300 miles from us. This time delay presum
              ably represents the time required to relay the
              report all the way back to Pearl via the aircraft
              communication channels and then send it back out
              on the submarine schedules. It is recommended
              that serious effort be made to get search planes
              and submarines on a common radio frequency while
              patrolling a common area.
    § September 1944
         0432 Entered area assign'd for patrol while waiting
              to join Zootormination on D-2 day (13 September).
              Decision was made to conduct surface patrol
              across area to western boundary; can then back to
              westward to give buttar area coverage in absence
              of the other branches of the pack
              and SEGUNDO rojoinf, SEATRO will patrol eastern
              lane of area in accordance with BER pack patrol
              plan for the waiting period.
  9 September 1944
       1116 High' parasites watch reported and periscope on the
              port quarter, range about 1500 yards (Ship con
              tract +ll). Evaded at enemy speed. Sighting
              was confirmed by two bridge lookouts and 7j.0.O.D.
              The description given by those sighting it is
              illustrated by sketch;
             It was soon twice. The last time.it was exposed
             the two or three feet, assuming that it might have
             been an envoy cargo submarine enroute to Palau
             traveling submerged by day, we patrolled on to
             southward and then cut across to place ourselves
             on his route to Palau at dark. Patrol bock along
              this route that might was unproductive.

Subject:                                 U.S.S. SEAHORSE - Report of Fifth War Patrol.

(1) RADIO

Radio reception of HAIKU was good at all times during the patrol except from 1900 to 2000Z when 90OC FCS faded out completely, and 4525 LCS was not reliable because of Japanese interference. The lack of reception during this hour has been noted on all of the SEAHORS&'6s five patrols. It is suggested that a shift to 14,390 FCS be accomplished at 1900 Z instead of 2000Z to remedy this. No effective interference by the enemy was noted on the HAIKU reception except that noted above.

The SD radar still continues to give objectionable interference, completely blocking reception at times. It has been noted, however, that the SD gives very little interference on the RBH-2 which is a Superheterodyne receiver.

The following is a tabulation of results obtained from all HAIKU listening frequencies:

| Centering Numeric Code | Tuning         | Result        |
||||
| 16,68 KCS             | Not used.    | Characteristic current. Fixed during glow hook-up. |
| 56 KCS                | Not used.    | Characteristic current. |
| 4525 KCS              | Good signal; slight current during | ship-signals in this area. Great current at night. Good readability. |
| 9090 KCS              | Characteristic current. Kew info detection otherwise impossible. Characteristic current. Cool black alert.    |
| 14,390 KCS            | Characteristic current. Kew intro/writing on waco (word aggregation humanized). Characteristic current. Most recent documentation recently updated with intellect and intuition. Characteristic current again. Cluster received but clearer. Characteristic current main box. Characteristic current operating => Possible to be identified. Characteristic current. Located at 10 year ship date. Characteristic current basic. Characteristic current and relatively readable lengthened in spite of increased fruit-shape.

All of ComSubPac soro I liers were received with the reception of number 26, 63, 62 and 83. Four messages were resurrected during attack patrol. Great difficulty was experienced in transmitting all but the last of five messages because of persistent jamming by the enemy. Because of weak signal strength BLL5 was copied with considerable difficulty while proceeding northward to the equator, but no messages were missed.

On the 4155 KCS Chunking broadcasts reception was very good with a loud and clear signal. It is suggested, however, that several schedules be established at night to insure that all messages were received.

12-38-30 (H) First hit in first target. First torpedo fired at second target at the instant the third torpedo hit up forward. These lark 14 hits were tremendous explosions - by far the best we have obtained with that torpedo. It is interesting in view of the fact that the torpedoes probably struck glancing blows under the counter of the target and the warheads were not crushed before going off. This confirms the theory concerning the effect of impact on the lark l4 torpedo. Two hits heard in the second target as we started down. The second target was also packed with th…

0837 (H) Sighted a JAKE coming out of a cloud with a zero angle on the bow at a range of about eight miles. We were making 18 knots, and thought the jig was up. Dived.

0857 (H) Ateroscale depth. Plane was cavorting over the convoy, zooming the ships, and apparently having a good time.

0920 (H) The pilot could hardly fly like he was and do anything else, so we surfaced, hoping that we would not be sighted.

0930 (H) Plane passed out of sight on course opposite to that of the convoy.

0953 (H) Sighted JAKE flying up the convoy's track. He was on a steady course at this time, and an SD radar range showed him to be at 12 miles. He slowed to 10 knots to cut down our wake until we were abaft his beam.

0959 (H) Back up to 18 knots, pulling ahead of the convoy. The plane maintained his steady course until he passed out of sight. He must have been blind to miss sighting us.

1026 (H) Commenced closing track, maintaining the range at 22,000 yards. The bridges of the ships were in plain sight from our bridge, but we were forced to cut corners in order to reduce the distance to the track in a hurry.

1058 (H) Divers just inside of the 100 fathom curve. The convoy base course was 3350 T., speed 6. By running in at standard speed submerged we would interact with the targets. We could not afford to stay on this surface any longer than absolutely necessary and risk a sighting. As stupid and blind as the plane occupies were, we did not want to stretch our luck any farther.

1156 (H) Sighted two engine bomber (WELL) flying a close A/S patrol over the convoy. A NOTE class DD was the only escort. The rest of the pack wore probably back there engaged in working over schools of fish. The destroyer was patrolling across the bow of the leading ship in the column of three. He would drop back abeam of the leader and then work up ahead, across, and then back down on the other beam. The first ship was an old hulk of about 4,000 tons. He was flying the convoy's pennants at his yard-

17 May 1944.

The Commander-in-Chief, UNITED STATES FLEET.
The Commander +SEVENTY FLEET.

Subject:
U.S.S. SEAHOUSE (SS304) — Report of Fourth War Patrol _
comments on.

1. The Fourth War Patrol of the SEAHOUSE was made under the.
operational control of Commander Submarines, PACIFIC FLEET and the
submarine was routed to Brisbane, Australia for refit under the temporary
operational control of Commander Task Force SEVENTY-TWO.

2. The remarks of the Commander Submarine Squadron EIGHTEEN are
concurred in except as regards evidence of sinking the submarine. The
single timed explosion in attack number four is believed insufficient
evidence to credit sinking.

3. It is noted that Jap depth charges encon.cred in counter
attack on 9 April apparently were set in excess of 435 feet, although
the large up-angle at this time may have caused an erroneous indication
of depth, if the charges were a considerable distance away.

4. This patrol is designated as successful for Combat Insignia
Award.

5. This is the third highly successful patrol for the SEAHORSE
and her Commanding Officer. The Commander Task Force SEVENTY-TWO con-
gratulates the Commanding Officer, officers and crew upon a highly suc-
cessful and aggressive patrol in the face of constant enemy op.o,osition and
anti-submarine patrols for inflicting the following damage on the enemy:

paring the torpedoes, the same experts completely sold the torpedoes
to our torpedo gang and at the same time gave them careful and de-
tailed instructions in their upkeep. The torpedometer's mates
in the after torpedo room knew that they had the best torpedoes in
the world, providing they took care of them as they were instructed,
and they did not hesitate to tell the commanding officer that he
h o u e u u - tnp  ;
had to divide because the torpedoes in the tubes had to come out for
charging, or something else had to be done to them that required the
ship to be steady. We consider this entirely proper, because, after
all, s u m b a r i n e is no better than its torpedoes, and a little extra
work or time lost is of no consequence. Our torpedodic officer, after
torpedo room gang and two electricians' mates responsible for the
Mk. XVII torpedoes we had aboard, hope to take another load t o u n
our next patrol. The fire control party is sold on them, and if we
return t o PAIAU, or a similar area, will request a full load of Mk.
XVIII torpedoes. It is highly desirable, however, -to provide sowe
more practicable means for handling a full load forward. -4 t h
present time, the bunks in the forward torpedo room would be useless
until one savvot, was fired.

The revised table 1 was prepared using the same S.E.A.S.H. file as above, was printed on 10/20/1960, mat 1000, copy 146. Not changed were color and weight changes during the test. The standard uniform temperature was 25,637F. The weight subsequently was assigned along with the seven heaviest figures 194,164,- these will be proportioned in the future to prevent inaccurate records from being misleading. Two copies of the five middle zeros of the original table will be retained for the S.E.A.S.H. file, the reader must verify that the orange file belongs to the test procedure.
