cut to the brief 5 hours of the northern summer night.
Hampered by fog, rain, and poor radio reception;
and lacking radar, fathometer, and deciphering equip-
ment; S-18 remained on patrol through the 10th. The
next day, she returned to Dutch Harbor. On the 13th,
she was underway again to patrol west and north of
Attu, then north of Kiska. The weather, as on earlier
patrols, was consistently bad. Habitability in the S-1
class boat was poor. Material defects and design limi-
tations in speed and maneuverability continued to
plague her.

S-18 (SS-123) was laid down on 15 August 1918 by
the Bethlehem Shipbuilding Corp., Quincy, Mass.;
launched on 29 April 1920; sponsored by Miss Virginia
Beil Johnson; and commissioned on 3 April 1924, Lt.
Elliot M. Senn in command.

From 1924 through 1929, S-18 operated out of New
London, primarily off the New England coast but with
annual deployments to the Caribbean for winter ma-
neuvers and fleet problems. Transferred to the Pacific
fleet in 1930, she departed New London on 24 May;
operated off the California coast into the fall; and
arrived at her new home port, Pearl Harbor, on 7
December.

For the next 11 years, S-18 remained based at Pearl
Harbor. In September 1941, she returned to the west
coast; and, three months later, after the United States
had entered World War II, the submarine was ordered
to the Aleutians.

A unit of Submarine Division (SubDiv) 41, S-18
moved north in mid-January 1942. Into March, she
conducted defensive patrols out of the new and still
incomplete submarine base at Dutch Harbor. In mid-
March, she got underway for San Diego; underwent
repairs there until mid-May; then returned to the
Aleutians.

En route, on the 29th, the S-boat received orders to
patrol the southern approaches to Umnak Pass in
anticipation of a Japanese attack. On 2 June, she took
up her station. The next day, the Japanese sent carrier
planes against Dutch Harbor and landed troops on
Kiska and Attu. The war in the Aleutians had begun.
Orders for submerged daylight operations in combat
areas compelled the World-War-I-design submarines of
the north Pacific force to increase their submerged
On the 29th, she sighted an enemy submarine but
was unable to close. The same day, she returned to
Dutch Harbor; and, as at the conclusion of previous
patrols, her commanding officer requested up-to-date
sound and radar equipment.

From 15 July to 2 August, the S-boat conducted
another patrol in the Kiska area; and, on completion
of the patrol, she was ordered to San Diego.

In October, S-18 returned to the Aleutians and, on
the 22d, she cleared Dutch Harbor for her next patrol,
again in the Kiska area. On 3 November, however, she
was recalled and ordered to prepare for a longer, more
distant patrol. On the 12th, she put to sea; but, on the
15th, a crack in the starboard main engine housing
forced her back to Dutch Harbor.

She arrived on the 20th, and her repairs were com-
pleted by the end of the month. On the 30th, S-18
resumed her patrol, moved west, and operated off
Kiska, Kiskinato, Agattu, and Attu. On 22 December,
after 16 days in her patrol area, she lost her starboard
stern plane; and depth control became erratic. On the
28th, she returned to Dutch Harbor.

Repairs and refit took S-18 into the new year, 1943;
and, on 7 January, she got underway again. During
that 28 day patrol, her last, she reconnoitered Attu
and the Semichi Islands. On 4 February, she was
ordered back to San Diego, for overhaul and assign-
ment to training duty.

For the remainder of World War II, S-18 remained
in the San Diego area, providing training services for
the West Coast Sound School. In late September 1945,
she moved north to San Francisco where she was
decommissioned on 29 October. On 13 November, her
name was struck from the Navy list; and, a year later,
her hulk was sold for scrapping to the Salco Iron and
Metal Co., San Francisco.

S-18 earned one battle star during World War II.

Subject: 1st. War Patrol of U.S.S. S-18, record of.

Reference: (a) CSS-45 Confidential Ltr. FC5-45/A16-3, Serial
0217 of 8 November 1944.

1. As requested in reference (a) it is reported that
their is no copy of the 1st. war patrol report in the files of
this vessel.

2. Examination of the ship's log discloses that the 1st.
war patrol of the U.S.S. S-18 was made in Alaskan waters and very
probably between the dates 15 March 1942 to 27 March 1942, depart-
ing and returning to Dutch Harbor, Alaska.

3. Lieutenant Commander William J. Millican was in command
of this ship at that time. It is believed that the Commander Sub-
marine Division FORTY-ONE was the Immediate Superior in Command and
that he was also the Commander Task Group 8.5.

4. No further information is available on this vessel.

Serial 028 of Apr.21,1942.
18 May 1942

From: The Commander Submarine Squadron FOUR.
To : The Commander Submarines, Pacific Fleet.
Subject: U.S.S. S-18 - Patrol Report - Forwarding of.

1. This report of the S-18's second war patrol was
received after the report of her third war patrol.

2. This report again emphasizes the difficulties
encountered by a small submarine operating in Alaskan waters dur-
ing the winter months. Their effectiveness at such times is
questionable.

3. One of the major defects encountered by the S-18
on its patrol was the icing up of the antennas. This will con-
tinue to be a source of trouble on all patrols in sub-freezing
weather with this type of antenna. The ice on the antenna not
only grounds the antenna to the hull, but the additional weight
soon becomes great enough to break the wires or bend the radio
stub mast so that the antennas sag dangerously near the deck and
superstructure. This condition makes both transmitting and re-
ceiving impossible until the antenna can be de-iced.

4. The difficulty of reception can be overcome by
providing all submarines going on northern patrols with the
"doughnut" type of loop antenna designed by Lieutenant P.C. Gail,
U.S. Naval Reserve, for underwater reception of radio signals.
This loop, which has been described in previous correspondence,
is completely enclosed in thick waterproof rubber outside the
hull, and therefore is not subject to the usual difficulties
caused by water or ice collecting on it. It has enabled vessels
to receive radio signals while submerged and has in some cases
been found superior to the flat top antenna for reception on the
surface when a suitable coupling unit is provided. Submarines
basing on Pearl Harbor and not equipped with direction finders
have been equipped with this type of submerged loop. However,
the difficulty of transmitting is not overcome by substituting
this loop for the flat top, and

CONFIDENTIAL
U.S.S. S-18 - REPORT OF 2ND WAR PATROL
Period from 7 February to 23 February 1942.

Area: 600 miles on course 240° from Attu Island, thence approxi-
mately 150 miles easterly on course 280° until 150
miles east of Paramushiru Island (northern Kuril group);
thence direct line back to Attu Island.

Zone time: for this report - zone plus twelve date and time is
used throughout.

1. Underway from Dutch Harbor, Unalaska 1030, 7
February. Sighted unidentified vessel 50 miles north of Unmak
Island afternoon of the 8th. Dove and conducted approach. Iden-
tified vessel as a Russian freighter on easterly course. Ceased
approach and surfaced. Entered Kiska Harbor afternoon of 11 Feb-
ruary and anchored to land sick man. Underway morning of 12th.

2. Almost continuous gales and subsequent rough and
mountainous seas were experienced. While the weather chart shows
zero percentage of calms in this area for month of February and
prevailing northwest winds, it is to be emphasized that these
winds are almost unceasingly of gale force. Speed frequently had
to be reduced to keep from burying the boat in the seas. On 19
February, in approximate position Lat. 50°N., Long. 160°E. ship
was forced to dive, it being impossible to keep green water from
coming down the conning tower hatch.

No thermometer survived topsides. The average air
temperature in the conning tower varied between 22° and 32°F.
During the days south and west of Attu bridge personnel were ex-
posed to constant drenching from salt water spray, hail, and snow
storms. Ice collected on the bridge up to two inches or more in
thickness. The gun was unusable due to its continual iced con-
dition, even had the personnel been able to keep a footing on
deck. The weight of the ice collecting on the radio antennas
broke two out of the three.

The engine water injection reached a low of 31°
for nearly a day in approximate Lat. 49°N., Long. 165°E. Keyport
Torpedo Station, Washington, advised against putting anything in
the torpedo water, hence considerable concern was experienced
over the possible freezing of the water in the torpedoes. The en-
gine injection water temperature rose soon after to about 34°.

U.S.S. S-18 - REPORT OF 2ND WAR PATROL, Cont'd.

10. Average rough sea conditions made depth control
uncertain and difficult. Fox schedules from Radio Bremerton (NPG)
on 58 (alternate 83), 3475, 9455, and 12,975 kcs. were copied
with the usual daytime fadings on low frequency. Three (3) or
more schedules simultaneously and received keyed simultaneously
when the antennas had been de-iced. The foregoing frequencies were
with 95% success on high frequency when the antennas had been
de-iced. 58 kcs. proved satisfactory shortly after evening twi-
light and the special submarine broadcast at 0600 (repeated at
1000) of proved wholly satisfactory throughout the patrol.

No information is available on density layers or
sound conditions owing to sea conditions and lack of target
respectively.

Owing to foul weather encountered during the patrol
and to the complete lack of contacts, it is believed that no ves-
sels other than Russian freighters enroute between Seattle and
Petropavlovsk, Russia, are operating in this area at this time.
It is also concluded that S-class submarines should not operate
west of Attu during February since the weather will not permit
them to properly fulfill their missions. Likewise, aircraft
operations owing to aforementioned visibility limitations.

The report of the S-23 fully explains habitability
conditions. This vessel concurs in full and in addition exper-
ienced lower temperatures and ice conditions. The consumption
of potable water averaged 1.9 gallons per man per day for all
purposes. Since so few dives were made on this patrol, it was
not necessary to water the battery. The height of the electro-
lyte was +1 point at the start of the patrol and -7 points at the
end of the patrol with 750 gallons remaining in the battery water
tank.

The crew returned in good health, dirty clothes,
and considerable "saltier" than when they left. Only a few times
was the mess set up since the motion of the ship took too high a
toll of unattended chinaware. The Kiska meteorological station (con-
sisting of four men) radioed Dutch Harbor for medical advice on
the sick man. His case was diagnosed as pneumonia. Fortunately,
the Kiska outfit had on hand, and on the doctor's radioed advice
administered, sulfa-thiazol. The man is recovering, although
still without other than radioed medical advice.

CONFIDENTIAL
U.S.S. S-18 - REPORT OF THIRD WAR PATROL
Period from 15 March to 27 March 1942.
Area: Southern approaches to Unimak and Akutan Passes, Aleutian
Islands.
Time: Local War Time, Willian (+10 z.d.) used throughout.

1. NARRATIVE.
1700 March 15 - Underway from Dutch Harbor, Unalaska to con-
duct submerged patrol in aforementioned area. Five days previous-
ly, the SS MOUNT McKINLEY, a 7500 ton merchantman chartered by
the U.S. Government, had run aground in Unimak Pass. Her SOS
calls revealed her position. On the two days preceding the start
of the patrol D/F bearings by shore stations fixed enemy trans-
missions 200 miles south of Unimak Pass. It was felt that the
vulnerable MOUNT McKINLEY would make excellent "bait" for an
enemy submarine.

0655 March 16 - Dove and conducted submerged patrol eastward
through Unimak Pass. Surfaced at 1904. Uneventful.

March 17 - 22 - Conducted submerged patrol in area 15 to 50
miles south of Akutan and Unimak Passes. Uneventful.

March 23-24 - Underway on surface on southwesterly course
due to heavy seas. Reversed course 180 miles south of passes.
Uneventful.

March 25 - Resumed submerged patrol on northerly course.

0600 March 26 - Dove and conducted submerged patrol through
Unimak Pass. Surfaced at 1954. Uneventful.

0615 March 27 - Dove and conducted submerged approach to
Dutch Harbor. 0800 surfaced and proceeded into Dutch Harbor.

2. WEATHER.
Weather closely conformed to that predicted by weather chart
for this area. On March 23 and 24 wind was from south, force 6
to 8 with corresponding rough seas.

3. TIDAL INFORMATION.
Set and drift are variable dependent upon the wind force and
direction. The opaqueness of the water observed in the Aleutian
Island area is marked. At depths below periscope depth it is

impossible to see any part of the ship through the periscope.
This is believed to be caused by, (1) the low altitude of the
sun during January through March. (2) the minute animal life
present in these waters. The currents through the passes check
with data in the "Current Tables".

4. NAVIGATION AIDS.
None.

None sighted nor heard.

6. AIRCRAFT.

7. ATTACKS.
None

8. A/S MEASURES.
None.

9. MAJOR DEFECTS.
None

10. RADIO RECEPTION.
Solid with the help of repeat schedule.

11. SOUND.
No targets. While proceeding through Unimak Pass on March
26 a waterfall was heard 10,000 yards away.

12. HEALTH AND HABITABILITY.
No alteration was made in ship's routine, numerous colds
developed due to dampness and usual low temperatures. None
serious.

13. FACTORS OF ENDURANCE REMAINING.
Torpedoes | Fuel | Lub. | Battery | Water | Provisions | Personnel
100%      | 84%  | 80%  | 60%     | 75%   | 20 days    | 20 days

14. This vessel and S-23 were directed to make preparations
to depart for San Francisco on 27 March, being relieved by the
S-34 and S-35 which vessels departed Bremerton that date. S-18
and S-23 departed Dutch Harbor on March 29, 1942.

15. Potable water consumed for all purposes averaged 1.5
gallons per man per day. It is to be noted that during the last
part of the patrol, the ship was submerged 14 hours a day. A
glance at the Nautical Almanac shows that on April 1 there are
only 5½ hours between the end of evening twilight and the be-
ginning of morning twilight. Between May 25 and July 25 there
is no period of darkness in these latitudes.

16. ADDITIONAL REMARKS.
    Since this vessel departed from Bremerton on 12 January
1942 all upkeep and routine repair work other than minor welding
has been performed by ship's force. Thus, time in port between
patrols has not been a period of rest and recreation. In spite
of this fact morale is extremely high. Except for a feeling of
disappointment that no targets were found all hands are keen and
watches are stood efficiently. However, all hands are physically
tired and their efficiency will begin to drop off rapidly unless
a leave and recreation period is afforded at first opportunity.

1. NARRATIVE.

15 July 1300(W)    In accordance with Commander Task Group Eight
                   Point Five's Operation Order Five dash Forty-
                   two underway from Dutch Harbor, Alaska, for
                   patrol area.

17 July 0500(X)    Arrived in patrol area and commenced submerged
                   patrol.

18 July 0400(X)    Received despatch orders from Commander Task
                   Group Eight Point Five to proceed to new area
                   in time to arrive in area prior to daylight
                   July 22. Area: Initial point bearing 241°T.,
                   distant eight-five miles from Sirius Point,
                   Kiska Island and maintain patrol along Sirius
                   Point bearing line to distance of 20 miles from
                   initial point.

19 July 2200(X)    Set course for new patrol area.

21 July 1600(X)    Arrived on station and commenced surface patrol.
                   Diving only during daylight when visibility, due
                   to fog, was reduced to such an extent that the
                   sound gear was more effective in detecting tar-
                   gets than possible by sighting. This condition
                   existed on this station consistently from 0500
                   to 1100 daily.

27 July 2300(X)    Received despatch orders from Commander Task
                   Group Eight Point Five to intercept one enemy
                   auxiliary and one destroyer standing north at 12
                   knots from Segula Island. Set course and speed
                   to intercept enemy at daylight.

28 July 0400(X)    Received despatch orders from Commander Task
                   Group Eight Point Five to return to patrol
                   station if enemy not contacted by daylight.
        0500(X)    Enemy not in sight, set course for patrol
                   station.
        1130(X)    On station, resumed patrol.

30 July 1000       Heard sixteen detonations from either depth
        1130 (L)   charges or impact bombs. No vessels were in
                   sight and no screws were heard.

U.S.S. S-18 - REPORT OF FIFTH WAR PATROL - PERIOD FROM JULY 15,

30 July 1415(X) Received orders from Commander Task Group Eight
                     Point Five to shift station along arc twenty-
                     five miles southwest. The heading of this
                     message was garbled but we believed it was for
                     us so we proceeded to new station.
       1845(X) Received orders from Commander Task Group Eight
                     Point Five to return to Dutch Harbor. The head-
                     ing of this message was also garbled. Set
                     course for Dutch Harbor and informed Commander
                     Task Group Eight Point Five of this action. No
                     reply from him indicated the message was for us.

2 August 1400(W) Arrived Dutch Harbor, Alaska.

2. WEATHER.

       The sea varied from being smooth to moderately rough. How-
ever, most of the time the sea was smooth. A dense fog was al-
ways present from 0400(X) to 1000(X) daily and as a rule fog was
present in the late afternoons and early evenings. About fifty
percent of the evenings were foggy. Star sights were never ob-
tained due to a constant early morning and evening overcast. The
only means of navigation was by advancing sun lines. Sun lines
were not obtained as often as desired due to overcast skies and
poor horizons.

3. TIDAL INFORMATION.

       The current was found to set eastward at 0.75 knots.

4. NAVIGATIONAL AIDS.

       None.

5. VESSELS SIGHTED.

       None.

6. AIRCRAFT SIGHTED.

       Three friendly PBY planes were sighted in the vicinity of
Dutch Harbor the first day of the patrol and one PBY plane in the
same vicinity on the last day of the patrol.

7. SUBMARINE ATTACKS.

       None.

8. ENEMY AS MEASURES.

None encountered.

9. MAJOR DEFECTS EXPERIENCED.

(a) During the early part of this patrol run a leak developed
between the bulkhead of number seven fuel oil tank and the reserve
lubricating oil tank, which is number eight fuel oil tank. Three
hundred gallons of lubricating oil was used from the reserve lubr-
icating oil tank prior to the lubricating oil from this tank becom-
ing contaminated to such an extent that it was no longer useable.
Remaining in the sump tank on 23 July was pumped into the reserve
lubricating oil tank and lubricating oil tank for the remainder
of this patrol run.

(b) On 28 July a zero ground appeared in the starboard main
motor compensating field circuit. The ground was located in the
jumper cable between the starboard main motor starting resistance
R2 and R3 as shown on blueprint 123-S-3-0-029-L. The breakdown of the
insulation on this cable was caused by the collection of moisture
by cable from sweating of forward engine room bulkhead. The star-
board main motor was out of commission for a period of seven hours
during which time the ground was located and reinsulated.

O. RADIO RECEPTION.

NPM Fox schedules were copied at all times with from good to
excellent reception. An attempt was made at 0400(W) on 18 July
to transmit our first message to NPM on the 4235 series using the
master oscillator as there is no crystal aboard for this frequency.
This attempt was unsuccessful and all others were cleared without difficulty
through NHB or NPR on 4805 kcs., crystal being used for this frequency.

Messages were not given serial numbers on this patrol.

1. SOUND CONDITIONS AND DENSITY LAYERS.

Although there was no opportunity to check sound conditions
due to the absence of shipping, it is believed that sound conditions
in this area are excellent. Past experience in this vicinity has
shown the above to be true.

Density layers were not investigated.

a few colds being the only ailments noted.

Habitability was only fair due to the damp air which eventually
made the bedding damp.

17. REMARKS.

During this patrol a change was made to COP 1161(B) by despatch.
This change was given to the other boats in this group by despatch
enciphered in the cipher machine. This vessel does not have a
cipher machine and consequently did not receive this change. The
same message came out in a system that we have but the radio oper-
ator failed to copy it solid and the message was useless.

Commander Task Group Eight Point Five was informed of the
above and stated that in messages to and from this vessel the old
system without changes would be used. This was satisfactory up
until the 30th of July. On this date two messages were received
by this vessel with garbled headings. From the text of the messages
it was correctly assumed that they were addressed to us and we
executed the action required by then.

To avoid a repetition of the above it is suggested that each
vessel prior to going on patrol be furnished a list of about thirty
names of trees, cities, rivers, etc., and that these names be used
consecutively in consecutive messages as internal indicators to

Enclosure: (A) Reference (a) with Enclosure (A) thereto.

1. The fifth War Patrol of the U.S.S. S-18 covered
a period of nineteen days, of which fourteen were spent on
station. Recall from patrol was made necessary in order to
prepare S-18 for departure for San Diego, in accordance with
directive from higher authority, for upkeep and Sound School
services.

2. The station of the S-18 on a patrol are north-
west of Kiska was dictated by covering operations for a
planned bombardment of Kiska Harbor by the Main Body. Weather
prevented the bombardment at that time and recall was timed
with its temporary deferment.

3. The S-18 had no contact with the enemy on this
patrol.

4. The Commanding Officer's decision to dive during
daylight only when visibility was reduced to such an extent that
sound gear was more effective in detecting targets than sighting
is not approved nor was it in accord with the doctrine established
by Commander Task Group Eight Point Five despatch 130111 of July.
That doctrine, which developed from several lost attack opportu-
nities through simultaneous sighting by submarine and target, is
that when visibility from the bridge and through the periscope
is approximately equal submarine patrol is conducive to the best
results. The use of sound gear under these conditions serves to
increase the effectiveness of the patrol.

5. The suggestion of the Commanding Officer with
respect to the use of internal serial despatch indicators was
placed in effect after his departure, all despatches being
addressed to the Task Group. Lack of an I.C.M. device in S-18
necessitated special handling of traffic to that ship.

(E) Copy of U.S.S. S-35 Third War Patrol.

1. The patrols of the S-18, S-31, S-32, S-33, and S-35
were all conducted under very similar circumstances, in areas very
close to each other and during the same period of time. No definite
contacts were made and no torpedoes were fired.

2. Kleinschmidt stills, and "SJ" Radars will be installed
in all S-class submarines when material is available. The Bureau of
Ships has informed this command that fathometers are now available
at San Diego at the rate of 4 or 5 per month. Three sets "JC" equip-
ment will be available at San Diego by October 1, 1942, and five
more in November.

3. The buoy mentioned on page 3 of the S-32 report may
have been a Dan buoy used to mark a mined or bombing area. This may
indicate the presence of mines in the area.

4. The thin plating in the superstructure of the HOLLAND
type S-class submarines has always been a weakness. The plan to
remedy this, suggested by the Commanding Officer, S-31, may have
merit and should be studied further. Comment on this, by the Com-
mander Submarine Squadron FORTY-FIVE, is requested.

5. The recommendation that a pharmacist's mate be allow-
ed for this class submarine is concurred in. This has been made
the subject of separate correspondence to the Bureau of Personnel.

2. As the war progresses, experienced personnel
will become less in number aboard each submarine. Many new
and inexperienced men will appear in submarine crews. It
is, therefore, necessary that commanding officers be ever
cognizant of this fact. They must direct their officers to
assure that they and all petty officers constantly train
these men to guard against personnel errors causing material
failures and subsequent early patrol terminations.

from patrol after nine days on station to remove a serious
dental case and to make her available for a full patrol on a
more distant station. Enroute to the new station, in start-
ing engines after a dive, the starboard main engine housing
was cracked as a result of turning over with water in the
cylinders. The S-18 is now undergoing repairs at the Sub-

1. The Seventh War Patrol of the S-18 covered a period
of twenty-eight (28) days, of which sixteen (16) days were spent
in patrol areas. The entire patrol was spent in areas dictated by
support of a Task Force operation. No contacts were made with the
enemy. The patrol was well conducted and each assignment was smart-
ly executed. Nevertheless, the lack of targets was noticeably detri-
mental to the morale of the crew.

2. Investigation as to the cause of the erratic depth
control on December 20 discloses that the starboard stern plane is
missing. An attempt will be made to shift the spare plane from the
S-35 to the S-18. A serious electrical fire occurred in the S-35
and damage is such that she can not operate submerged until she is
completely overhauled. The knock and misalignment in the port main
motor will be corrected.

    poles. As decision was made not to use the port motor except in
    emergency. Port engine was used on the shaft because the engine
    clutch helped steady the shaft. This bearing gave lesser symptoms
    of the same trouble on the last patrol.

1. This patrol covered a period of twenty-four
days, of which fifteen days were spent in the patrol area.
The reconnaissances of HOLTZ BAY, CHICHAGOF HARBOR and SAR-
AJA BAY were very complete, but those of the SEMICHI ISLANDS
should have included the southern sides to make the negative
information conclusive. No contacts were made.

2. The weather conditions encountered were sev-
ere, but typical in this area during the winter months. The
morale of the crew and the material condition of the S-18
was excellent considering the severity of this patrol. She
will depart for SAN DIEGO when ready for scheduled navy yard
overhaul.
