1. SEADRAGON departed Scarbabaja to continue on her own power as her skillful crew worked her out into the Bay. Her leaks were plugged and her pressure hull patched in time to take aboard a part of Admiral Hart's staff at Manila. She departed 16 December 1941 for Scerabaja, Java, Netherlands East Indies, where additional repairs were made.

On 30 December 1941, SEADRAGON departed Scarbabaja to conduct her First War Patrol in the South China Seas. On 6 January 1942 she entered the Celebes Sea. On 10 January she twice at t.c.d.a convoy without success while off Cape Varella. On 17, 23 and 25 January she delivered a series of attacks on convoys but obtained only one hit for unverified results. An attack made 1 February was successful. Her luck changed, 2 February 1942, when she attacked a convoy of 2 transports and sank passenger cargo TAMAGAWA MARU of 6,441 tons (170-16N; 119-48'E). She arrived at beleaguered Corrigedor 4 February 1942. Here she loaded two tons of submarine spares, 23 torpedoes, 19 menbers of a naval Radio Intelligence Unit, an Army Major, and 2 naval officers. Departing 5 February, she delivered her cargo and passengers to Scorsabaja then steamed to Fremantle, Australia, arriving 13 February 1942.

SEADRAGON departed Fremantle, 18 March 1942, on route for the second War Patrol in the South China Sea. She had not reached her target area, 31 March, when she was ordered to Cebu to pick up rations for the war effort. She reached Cebu on 3 April and unloaded 12 torpedoes with 250 rounds of 3-inch ammunition to make room for 34 tons of food, then sped for Corregidor, arriving 6 April 1942. Her men worked at a dining speed but had only time to unload seven tons of cargo before Commander Sixteenth Naval District ordered her away from the dock. She stood by off Corregidor for 40 hours, after which time LCDR Furtful was informed that further unloading was not feasible. She took aboard evacuees which included communications officers, 18 enlisted men and an Army Colonel, then headed south for Fremantle where she arrived 26 April 1942.

On 11 June 1942, SEADRAGON departed Fremantle to conduct her Third War Patrol. On 29 June, she reached the Singapore-Pong Kong steamer lane. In the early morning of 12 July, she made two hits which sank cargo HIYAMA MARU of 6,171 tons (130-08'N; 109-33'E). The following day she sank passenger cargo SHINO MARU of 4,163 tons (130-04'N; 109-39'E). In the vicinity of Cape Varella, 16 July, she attacked a convoy of four ships. Torpedoes fired at the second ship in column missed. But SEADRAGON fired two more at the last ship and was rewarded with two hits which sank cargo HAKODATE MARU of 5,302 tons (120-55'N; 109-29'E). She returned to Fremantle, 2 August 1942.

One of the early submarine stories emanating from the Southwest Pacific concerned SEADRAGON. Within the period of her first two war patrols, Japanese propagandist Tokyo Rose circulated a strange report over the airways of Radio Tokyo that the Americans had sent a fleet of red pirate submarines to prey on hapless troop transports and munition ships of Japan. She promised death to the red pirates. Radio monitors may have been mystified but the men of SEADRAGON knew the obvious answer. Her paint scorched and blistered during the attack on Cavite, had flaked to expose her red-lead undercoat and by the time of her first arrival at Scarbabaja, she resembled a shedding lizard. It is

1942, SEADRAAGON departed Fremantle for her Fourth War Patrol in the South China Sea. On 11 September 1942, Seaman First Class Darrell Dean Recorder fell...unconscious to the deck. F'hamacist Wate First Class Wheeler B, Lipes recognized the symptoms of appendicitis and reported to Lieutenant Commander Ferrali that it might be peritonitis and that immediate operation was imperative. He had qualified as a lab technician and acquired a special rating as radiographer. He had seen appendectomies performed but had never expected to perform surgery. When asked by Lieutenant Commander Ferrali if he could perform the operation, Lipes stated "Yes, sir, it's his only chance". SEADRAAGON submerged to select an operating staff. He chose Lieutenant Norvell Ward to act as his chief assistant. Communication officer Lieutenant Franz Hoskins served as enscheftier. Engineer Officer Lieutenant Charles C. Manning, played the part of chief nurse. Lipes improvised surgical instruments. He fashioned a handle for the scalp. Bent exposed served as muscular retractors. A tea strainer became an ether mask. The instruments were sterilized in a solution of torpedo alcohol mixed with water and boiled. A searchlight was rigged over the wardroom table. Lipes removed the appendix and sewed up the incision with catgut in veteran men's. An antiseptic powder made of ground-up sulfa tablets was applied, and bandages completed the successful operation. Lipes was lauded by the Medical Profession for his expert surgery, cited as an example of Navy training and salty submarine grit. SEADRAAGON's operation became a household word and a legend of the submarine force. This remarkable feat was later duplicated by men of other submersives.

On 22 September 1942, SEADRAAGON made unsuccessful attacks on a cruiser and a cargo ship, and on the night of 30 September, another attack was broken off when she was illuminated by searchlights and forced down by enemy escorts. In the vicinity of Makassar Straits on 10 October 1942, she fired two torpedoes for two hits which sank 1st Class SEADRAAGON. She was destroyed on 2 November 1942 and underwent routine overhaul.

On 23 November 1942, SEADRAAGON departed Brisbane for her Fifth War Patrol, conducted in the area east of New Britain in 1st, George's channel. In the vicinity of Rabual on 8 December 1942, she fired torpedoes at a destroyer. Put the first torpedo threw a plume of smoke observed by the destroyer who maneuvered clear and SEADRAAGON was forced down. On 11 December 1942, she fired two torpedoes at another destroyer, observing one hit as she dived to avoid depth charging. On 20 December 1942, she fired four torpedoes at an enemy submarine headed for Rabual. A leak of fire and black smoke appeared over the stern of Japanese submarine 1-4 of 1,995 tons. She was observed to

20 June 1956 and she was launched 16 August 1958, under the sponsorship of Mrs. Robert L. Dennison, wife of Vice Admiral Dennison, Deputy Chief of Naval Operations (Plans and Policy). The nuclear-powered attack submarine was commissioned 5 December 1959, Lieutenant Commander George P. Steele, USN, in command. Based at New London, SEADRAGON is scheduled to leave that port in August 1960 for a new home port of Pearl Harbor. In making passage to Pearl Harbor she will make the first east-west transit of the Arctic Ocean, collecting data on operations in the Arctic Ocean and will survey ice conditions. She will also cruise under the polar ice to the North Poles.

5 December 1959, Lieutenant Commander George P. Steele, USN, in command.

SEADRAGON has a length overall of 267 feet, 8 inches; extreme beam of 25 feet; light displacement of 2382 tons; submerged displacement of 2861 tons and complement of 10 officers and 75 men. An attack-type submarine and a sister ship of the famed SKATE (SS(N) 578), she is equipped with the most advance submarine weapons and also has the capability of guiding to target, missiles which have been fired by other ships. Though designed for 85 men to live comfortably while submerged for long periods of time, she and other nuclear-powered submarines are equipped with respirators packaged in synthetic leather and stored in various parts of the ship. Each lightweight respirator had either a ten or twenty-five foot length of hose that connects with a full-vision facepiece containing a speaking diaphragm. The wearer can plug into any of the outlet position which draw on the submarine's low-pressure air system. This system has a number of 3000-pound pressurized tanks - used for surfacing and torpedo firing. The air is reduced to 100 pounds of pressure before passing through a filter into the mask. The filter removes vapors and other matter. This special breathing gear is especially designed and placed to be reached quickly during any condition that would not permit the crew to breathe the ship's normal air supply. One such condition would be in case of fire under the Arctic ice pack when the submarine can't surface. A speaking diaphragm permits use of the submarine's sound power telephone system during an emergency. SEADRAGON's reactor plant is an advanced type of the one that powered the NAUTILUS and SKATE on their voyages beneath the Polar ice cap. It should propel her over a hundred thousand miles without refueling.

After commissioning, SEADRAGON departed for the Caribbean for shakedown cruise, during which she visited San Juan, Puerto Rico, and St. Thomas, Virgin Islands. She then returned to Portsmouth to prepare for the first East-to-West Arctic passage of a submarine from the Atlantic to the Pacific. Embarked for this cruise was Arctic expert Commodore Owen C. S. Robertson, RCN, Canadian Naval Attache in Washington, and a team of scientists who would make hydrographic and oceanographic studies, including the use of sonar and underwater television to study the ocean around the submarine, the sea ice overhead and the bottom below. By watching the monitor screens inside the submarine, crewmen could watch the ice, keeping a lookout for "ice lakes" where the ice is relatively thin and the submarine could break through and surface.

SEADRAGON took aboard the first undersea video tape recorder which would keep a record of the under-ice "Ceiling" on the polar trip. This video tape will be played back by television receivers placed in the "porthole" to provide a realistic view of the underside of the ice cap for crews training in hazardous polar navigation. A joint Navy-RCA effort, the video tape recorder uses tiny transistors instead of vacuum tubes, and is small enough

20 inches by 20 inches by 100 inches) to fit into a torpedo rack. This is sixty percent smaller than usual commercial tape equipment.

On 1 August 1960 SEADRAGON got underway from Portsmouth and headed north between Greenland and Labrador through Baffin Bay where she dived under an iceberg 74 feet long and 180 feet deep. Later SEADRAGON nosed down more than 300 feet to get under an iceberg 879 feet wide and 1,471 feet long. This was the first leg of her voyage in carrying out orders to transit to the Pacific by way of the Northwest Passage and the North Pole.

On Monday, 15 August 1960, SEADRAGON entered Lancaster Sound, the first leg of the Parry Channel. The time between this date and the date of her departure from Portsmouth had been occupied with making the transit, calibrating special ice equipment, and investigating various icebergs encountered in transit. Now she was ready, her men and equipment peaked for the meat of her mission.

The Parry Channel, named for Sir Edward Parry, an English explorer who first discovered and entered it in 1819, is covered for most of the year with heavy pack ice. Moreover, beyond Lancaster Sound, little of the channel is charted. In fact, for the passage beyond Lancaster Sound, the SEADRAGON's Commanding Officer, Lieutenant Commander George P. Steele, USN, used Parry's original journal of his voyage as the best navigational information available. Parry Channel appears on most maps, reading from east to west, as Lancaster Sound, Barrow Strait, Viscount Melville Sound and McClure Strait.

Passing through Lancaster Sound, Barrow Strait, Viscount Melville Sound and McClure Strait, SEADRAGON completed the first transit of the Northwest Passage by any ship at 0215, 21 August 1960, and headed for the North Pole.

Having already passed the North Magnetic Pole during her transit of the Parry Channel, the North Geographic Pole seemed a logical next step. At 1011, 25 August 1960, SEADRAGON became the fourth ship to reach the North Pole. Here, SEADRAGON's crew took time out for a few innings of baseball which saw the players running completely around the world when they rounded the bases, and knocking a home run all the way into tomorrow. The baseball diamond was laid out in such a way that a runner leaving the plate would arrive at first base 12 hours later.

Upon departing from the North Pole, SEADRAGON headed for the Bering Strait and the Pacific. After first calling at the scientific station on Ice Island T-3, she transited the Bering Strait on 4 September 1960 and moored alongside Coast Guard cutter NORTHWIND at Nome, Alaska. Lack of berthing facilities forced the submarine to use the cutter as a dock. Lieutenant Commander Steel received the personal congratulations of Rear Admiral H. H. Caldwell, Commander Alaskan Sea Frontier. He then moved on board NORTHWIND and was presented a key to the city by Nome's mayor, Steve Anderson. A lovely beauty queen presented a hand-sewn sealskin plaque to SEADRAGON from the people of Nome. Across the top was the Eskimo word "Pilautomosine," meaning "may the best of everything be yours."

Report of No. 1 Vr report
(1) General Report (Continued)

The OT was found to be protective early in the trial and not used thereafter.

The U.S. is not visible in V-formation.

A two on per-session sound watch. It is submerged and not seen per-session in the surface. In only one case was it seen to be less than 3000 yards in most cases.

6. Continue timing:
   - Off into China was reported to be 6.5 hours, but 7.0 hours until midnight and then to be 6.5 hours. After 0300, report was reported to be 7.0 hours.

2. Changes made to the report:
   - Around 11:00 a.m. it was reported to be 6.5 hours.

A few of 2/3's trials were missed.

7. Speed used:
   - Speed used was not an in-proceeding to, between, or from station. On station the artillery engine was used on propulsion mostly. A main engine and auxiliary was used in the 3rd and 4th. It was not of advantage operations the following day. The 2nd was used to the 3rd and 4th.

— page 47 —
9. Torpedo net health.

The spirit and morale of the men was excellent throughout the patrol, and we were considerable in view of the great strain and long working hours. Hours were forced to endure from 10 December until the start of the patrol. Even in Sourbayne there wasn't anything for relaxation.

Much nervousness was shown on first contact with the enemy sound patrol but degenerated on subsequent encounters, though no one likes to hear their plight.

Diet deficiency was noticable, especially by the large number of cases of sore gums after about the third week. Numerous cases of Diarrhoea were reported.

On Monday, 26 January, about one-third of crew suffered from food poisoning, believed to have been caused by best served Sunday, midnight. This necessitated going to watch and watch among the heli-ty men for 24 hours.

Crew morale was good. The crew was reported as being transferred to the tender.

All hands lost weight during the patrol.

10. General Remarks:
   (a) More 7x50 binoculars are needed. Present allowance of 4 does not permit the commanding officer to have one for use on the bridge. It is felt that each boat should carry at least six so that there will be one spare available to replace any that may become damaged or flooded.

(b) There are only 44 bunks installed necessitating the use of hot bunks. At present there are no mattresses for these. It being necessary to throw them all overboard. A most unsatisfactory condition. In port it is necessary for 1/3 of crew to sleep ashore or on the deck. Bunks were lost in Carite.

   Observed two DD and 1 air patrol escorting 7 A.F.s, 1 DD was ahead of convoy and 1 DD was at 2D of convoy.

2. Violin of Subic Bay

   At 03:48, Wednesday, April 8, 3 Submarines sighted DD on southerly course and at 04:35 this DD reversed course to north. At 03:10 DD observed on south-belly course again. From observations of movements it is believed this DD patrolling line Cabra Island to Subic Bay at speed of about 10 knots, alternately echo ranging and listening.

   At 0805 Saturday, April 11, sighted at 4th DD standing toward Subic Bay from Cabra Island following some sound tactics. At 1649 following some sound

(1) Major defects and casualties

DEFECTS:
Same defects as items 1, 2, and 4 of previous report.

CASUALTIES:
1. Scored rod on #4 main engine.
2. Cracked lower liner in #2 main engine. This engine was in commission for only a short time on this patrol. When final adjustments were put on on 1-15th it was discovered that clearances between altered crosshead nuts where improper and it was not until March 26th that #2 main engine was motorized. A scored rod revealed that a lower head was cracked and as no grinding in tool was visible a spare could not be fitted.
3. Babbit band worn away on one piston of #1 main engine.
4. Ice machine circulating water discharge line leaking in negative tank.
5. Drain line developed more holes.
6. Two-way speaking system Conning Tower transmitter cable flooded out.

   - Adequate supply of both maintained.
4. Sound Gear:
   - An increase in accuracy and efficiency of sound personnel was noted on this patrol.
5. Communications:
   - No remarks.
6. Speeds Used:
   - One and two engine speeds were used to maintain schedules, changed, then higher speeds were used to maintain schedules. Fuel was not a consideration after change of mission.
7. Navigation:
   - The position of ship was accurately known at all times.
8. Morale and Health:
   - Morale was excellent.
   - Health on this patrol was much better than on previous patrol. An adequate supply of vitamin tablets is believed vital in maintenance of health of crew.

2 WAR FACTOR
(1) General Remarks (Cont'd)
9. General Remarks:
(a) More 7 x 50 binoculars are needed.
(b) All torpedoes on board were received from Corregidor Feb. 4, 1942, and prepared for firing immediately. They have been in fully ready condition since. All torpedoes were given a thorough check on March 30-31, running engines on air and operating steering and depth engines. Storing provisions in torpedo rooms has prevented inspection of the torpedoes since then.
(c) It is recommended that all submarines be provided with the latest publications for purposes of warship and merchant ship identification. Present ones are considerably out of date.

While making approach on above ship sighted a convoy of four ships bearing 327 true, range about 16,000 yards, zig zagging on about base course 135 true, ships in line bearing similar to TURKAL M.K.U type 9 knots. At first three ships were similar to TURKAL M.K.U type freighter o. about 7000 tons. Leading ship unidentified as to type. It was camouflaged with blue, gray, and white paint, and looked like a large edition of the BUSHBELL.

Lat. 00-13-00 S. Long. 118-39-00 E. Sighted a submarine bearing 195 true, range 8,000 yards, on northerly course. Believed to be TAUTOG. Ran to eastward to avoid.

: 25 July 1942

Lat. 2-55-10 S. Long. 118-33-00 E. Sighted smoke bearing 043 true, and heard faint pinging on port side. At 1745 sighted masts of ship bearing 060 true, ship on southerly course.

Ship passed abeam, hull down but determined to be a freighter and from position determined it to be on course 175 true, standing down for Mackassar City.

Pinging faded out, but at no time was any escort seen. At 1902 surfaced with intention of gaining position ahead for moonlight periscope approach if possible, and if not, a position for dawn attack north of assumed northern entrance to Mackassar City. Determined target speed of 10 knots by tracking. However, at 2021 Sighted ship bearing 195 true, having all appearances of a DD he'd decided directly for us, so dove to 200 feet.

However, sound could not hear any screws, so knew it must have been a sail boat.

Surfaced and continued pursuit. However, the 34 minute delay precluded any possibility of moonlight periscope approach, and assumed presence of escort vessel determined against surface attack after noon sent at 0300. Therefore stood down for a point 7 miles ahead of where ship should be at dawn.

Dove in Lat. 5-15-00 S. Long 118-36-00 E when it was thought the target was seen looming up in the morning haze. However, smoke of the ship was not seen below the horizon until bearing 359 true. The bearing of the smoke changed rapidly to the right and it was determined that the ship was making an entrance in the vicinity of Lt. 5-00-00 S, much to our chagrin. This may be the regular entrance for south bound ships or warning of our presence may have been given by a lookout posted in one of the many fishing vessels we had great difficulty in avoiding in that vicinity. The ship itself was never seen after dawn.

5. DATE: 13 July 1942
LOCATION: Lat. 13-05-30 N, Long. 109-36-00 E.
METHOD: Periscope - Mark VI PARISCOPE BEARING: 345-1/2
GYRO ANGLE: Zero
TARGET COURSE: 340 true
TARGET SPEED: 12 knots (104 rpm) MASTHEAD HEIGHT USED: 110 ft.
TARGET NO.: 1, and 3
PLATING INTRAVAL: 0 - 10 sec.
FIRST SET OF AIM: Bow, Stern
1 hit TIME TO ALIOLION: 00 sec. TORPEDO RUN: 1500 yards

First torpedo hit about 50 feet ahead stem. Ship settled rapidly by bow, 5 minutes after explosion his bridge was awash, stern well up. 12 minutes after hitting, an explosion was heard as it hits boilers had gone up. At 0705 there was no trace of the ship. Gave a few of the men a look at a sinking ship. Good on moral.

6. DATE: 16 July 1942
LOCATION: Lat. 12-55-30 N, Long. 109-29-15 E.
METHOD: Periscope - Mark VI PARISCOPE BEARING: 190-1/2

TARGET SPEED: 110 ft. SIDEWAYS: No. 5 and 6
PLATING INTRAVAL: 0 - 8 seconds
PENNITS OF AIM: Foremast, mainmast. Both missed
PERISCOPE DEPTH: 63 feet

Believed both passed under the target. Torpedo run too short for torpedoes to take proper depth, and perishes that had not fully armed. A range taken about two minutes after firing was 1250 yards. At 4-45 and 4-56 minutes after firing explosions were heard as the torpedoes hit the beach.

1. On 4 July 1942 the target fired upon at 0747 turned down torpedo track and commenced firing bow gun at periscope. Later explosions wore heard as if the ships dropped about 1/2 depth charges indiscriminately.

2. On 4 July 1942, at 1345, which was 33 minutes after conducting attack, the submarine was in position to attack the torpedo and depth charges. At 1345, the submarine was in position to attack the torpedo and

two niles to southward at which time he changed course to the south again disappearing at 2345 on a bearing of about 160 true. At 0044 surfaced and ran out to northeastward. This vessel was at 260 feet during depth charging and remained deep until surfacing, with exhaust valves leaking badly throughout. To avoid using the [CRUZ pump, which pounds heavily, the water in the engine room bilges was removed by a bucket brigade and put in #3 and 4 sanitary tanks which were blown overboard when full. Not the best method, but satisfactory.

4. 16 July 1942, after attack on convoy the enemy retaliated by gun fire at first and then numerous explosions were heard about 30 minutes later as if they were coming from light airplane bombs. A general hit and miss pattern, none very close.

5. 26 July 1942, after attack on freighter the small escort vessel came down the track and dropped two depth charges near the point of firing, steamed around for a few minutes then departed.

6. From observations it is believed an air patrol is the only general A/S measure in use along the Indo-China Coast with an A/S vessel being employed when available and when submarine activity becomes very pronounced in one locality.

Torpedo Data Computer - While conducting sound exercises with H.M.S. VOYAGER it was discovered the range would not generate. Complete investigation disclosed the reason to be a mechanical failure in the Range Resolver Unit. This could not be repaired without complete disassembly of the machine which was impracticable with facilities at hand. The Torpedo Data Computer could be used for firing with an instantaneous set up, but not generation or tracking.

10 June 1942

Number 4 Main Engine - Scored Piston rod on #6 unit.

26 June 1942

Number 1 Main Engine - Broken Piston Rod on #9 unit.

28 June 1942

Number 1 High Pressure Air Compressor - Discharge line from 4th stage split. An improvised patch lasted for about 2 weeks until the split became progressively longer.

10 July 1942

Negative Tank - Gasket worked loose permitting tank to fill when submerged.

27 July 1942

Number 4 Main Engine - Lubricating Oil discharge line from engine to purgatory cracked. Unable effect repairs. Engine out of commission.

Instantonous Overload Relays to Port Motors Flashed - Disconnected instantaneous overload circuit on port side.

QC Sound Gear - A slight binding was noted near the start of the patrol which made training difficult. This binding became progressively worse until on 26 July it became impossible to train or raise the sound head.

1. RADIO RECEPTION WAS VERY GOOD THROUGHOUT THE PATROL. AT TIMES VIAD FADED OUT TO A VERY WEAK SIGNAL, AND ON A FEW OCCASIONS JAMMING WAS NOTED. HOWEVER ON THOSE FEW OCCASIONS THE SCHEDULES FROM VHM WERE COOLIES. IN GENERAL IN THE SOUTH CHINA SEA VHM WAS CLEARER AND SIGNAL STRENGTH GREATER THAN VIXO.

2. ON 4 JULY 1942, IN THE VICINITY OF LAT. 12° 18' N., LONG. 109° 36' E., A LAYER OF FRESH WATER BETWEEN 120 AND 70 FEET WAS ENCOUNTERED, MAKING IT NECESSARY TO PUMP OUT 6000 POUNDS IN ORDER TO PENETRATE AFTER HAVING RUN AT 280 FEET FOR A NUMBER OF HOURS WITH A 1/3 TRIM.

3. SOUND CONDITIONS IN THE SOUTH CHINA SEA IN DEPTHS OF WATER LESS THAN 100 FEET WERE VERY POOR WITH CONSIDERABLE WATER NOISE EXISTING. ON 4 JULY, THE RANGE TO THE TARGET HAD DECREASED TO 1500 YARDS BEFORE SOUND COULD HEAR THE SCREAMS.

4. WITH 60 MAN ON BOARD, BERTHING ARRANGEMENTS WERE NOT OF THE BEST. WITH 46 TUNKS AVAILABLE, AND USING HOT BUNKS, IT WAS STILL NECESSARY FOR A NUMBER OF THE MEN TO EITHER REMAIN AWAKE OR SLEEP ON THE DECK. THE ONLY SOLUTION SEEN AT THIS POINT IS TO CARRY EXTRA MATTRESSES FOR THOSE WHO MUST USE THE DECK.

5. WITH THE V-POR COMPRESSION STILL IN OPERATION NO TRUMPET WAS EXPERIENCED IN MAINTAINING SUFFICIENT POTABLE AND BATTERY WATER TO MEET ALL NEEDS. IT WAS NOT NECESSARY TO RUN THE STILLS WHILE SUBMERGED. THE MINIMUM AMOUNT OF POTABLE WATER ON HAND AT ANY TIME WAS 3540 GALLONS. THE BATTERY WAS RUNNING WELL.

6. ON TWO ATTACKS, THE FIRST AND THE LAST, THE TORPEDO DATA COMPUTER WAS SORELY MISSED FOR TRACKING PURPOSES, ESPECIALLY IN THE LAST. IT IS FELT A TRUER ESTIMATE OF THE SPEED WOULD HAVE BEEN OBTAINED IN BOTH CASES, AND ESPECIALLY THE LATTER, WHERBY A 2-1/2 KNOT DIFFERENCE IN SPEED WAS REPRESENTED BY A 5° ERROR IN TARGET COURSE, USING A MOORING BOARD SOLUTION. SUFFICIENT TIME WAS NOT AVAILABLE TO GAIN ANY INFORMATION FROM A TIME BEARING PLOT. ON ALL OTHER ATTACKS THE LACK OF A TORPEDO DATA COMPUTER WAS NOT OF ANY CONSEQUENCE, AND ITS ABSENCE NOT FELT. EVEN BEFORE THE TORPEDO DATA COMPUTER WAS FOUND TO BE OUT OF COMMISSION, IT WAS THE INTENTION TO PARALLEL IT WITH A TIME BEARING AND MOORING BOARD PLOT, SINCE THE ADDITION OF A SIXTH OFFICER HAS MADE THIS PRACTICABLE.
