Seadragon

 

I

 

A small fish more commonly called the dragonet.

 

(SS-194: dp. 1,450 (surf.), 2,340 (subm.); l. 310'6"; b. 27'1"; dr. 13'8" (mean); s. 20 k. (surf.), 8.75 k. (subm.); cpl. 55'; a. 1 3", 8 21" tt; cl. Sarao)

 

The first Seadragon (SS-194) was laid down on 18 April 1938 by the Electric Boat Co., Groton, Conn.; christened during an attempted launching on 11 April 1939; sponsored by Mrs. J. 0. Richardson; and commissioned on 23 October 1939, Lt. John G. Johns in command.

 

Following a shakedown cruise off the east coast and in the Caribbean, Seadragon returned to New England and, on 23 May 1940. departed New London for the Philippines. With ComSubDiv 17 embarked, she arrived at Cayite on 30 November and commenced training operations as a unit of the Asiatic Fleet. A year later, she prepared for overhaul; and, by 8 December 1941 (7 December east of the International Date Line), she had started her yard period at the Cavite Navy Yard.

 

Two days later, on 10 December, she and Sealion (SS-195), moored together, were caught in an enemy air raid against Cavite. Sealion took a direct hit which demolished that submarine and damaged Seadragon, The force of the explosion ripped off part of the latter's bridge. Shrapnel and splinters punctured her tanks and pierced her conning tower, killing one and wounding five. The heat of the explosion scorched her hull and blistered her black paint.

 

Fires and explosions raged along the wharf. A nearby torpedo shop went up and flames reached toward a lighter, loaded with torpedoes, alongside Scadragon and Sealion. Pigeon (AM-47), however, disregarded the danger and moved in to tow Seadragon out into the channel, whence the submarine continued into Manila Bay under her own power.

 

Temporary repairs were accomplished by Canopns (AS-9) and Pigeon; and, on the night of 15 December, she embarked members of the Asiatic Fleet staff. At 0000, 10 December, she headed out of Manila Bay.

 

Escorted by Buhner (DD-222), Seadragon moved south, via Surigao and Makassar strait to Soeraba.ja, where she disembarked her passengers; received further repairs, exclusive of a paint job; and prepared for her first war patrol.

 

On 30 December, the submarine departed the Dutch naval base and set a course for the South China Sea to intercept Japanese shipping off the coast of Indochina. On 8 January, she was in the sea lanes to Cam Ranh Bay. Two days later, she sighted a destroyer; fired two torpedoes which missed; then watched as the destroyer continued on its course without attempting to attack the submarine. Seadragon remained in the area. Shortly after noon, a convoy was heard. One-half hour later, it was sighted, and the submarine began closing the last ship in the column. Shortly after 1300, she fired; missed; and again tried to close to firing position. Within an hour, however, the convoy was safely into Cam Ranh Bay. Seadragon retired eastward. After dark while on the surface, recharging, she sighted a destroyer and attempted to slip away undetected. The destroyer spotlighted her. Seadragon went deep and worked her way eastward through two depth charge attacks.

 

She spent the morning of the 12th evading Japanese patrol planes. In the afternoon, she closed a six-ship convoy; but, as she came to periscope depth for a final check, she was spotted from the air. Three salvos of bombs dropped close aboard, but Seadragon went deep and again made her way eastward—this time to investigate the cause of the plane sightings. She surfaced after 1800. No oil or air leaks were spotted; but her black paint was coming off the entire hull. Red lead undercoating showed from the waterline to the side plating, and, "in spots," on the bow planes and propeller guards. In shallow tropical waters, her original black paint was easily spotted against a light colored background. With red showing, she stood out, regardless of the color of the seabed. From then on, Seadragon ran at 140 feet between periscope exposures, except in areas known to be patrolled by air. She then went to 200 feet.

 

On the 14th, she patrolled in the Cape Varella area. On the 15th, she shifted southward; and, on the 16th, she stood off Hon Lon to wait for a convoy. At 1115, after a periscope observation, she was again spotted and bombed from the air. She returned to Cape Varella where the depth of the water permitted a closer patrol to the shore line.

 

During the next six days, she sighted several targets, but had no luck with her torpedoes. Early on the 23d, she sighted a four-ship convoy which she stalked until daylight, then attacked. At 0806, she fired at the lead ship and scored with a hit on the port quarter. She then fired two at the ship and missed. The third and fourth ships ran off to the southeast and west, respectively. The second ship moved in toward the first; then, listing to port and down by the stern, accompanied it as it ran for the beach. Seadragon surfaced and went after the third ship, but the appearance of an enemy plane forced her to break off the attack.

 

The submarine remained off the Indochina coast for another four days; then set a course back to Luzon. On the 29th, she began patrolling along the coast from Subic Bay to Lingayen Gulf. On 1 February, she took up station off San Fernando and, early on the morning of the 2nd, conducted a night submerged attack on a five-ship convoy. Tamagawa Maru, the fourth ship in line, went down, depriving the Japanese occupation force of a number of the reinforcement troops and the equipment she carried.

 

After the sinking, Seadragon patrolled southward. On the 4th, she arrived off Luzon Point; and, that night, she moved into Manila Bay to take on cargo and passengers at Corregidor. Mooring at 2203, she completed loading torpedoes, radio eauipment, and submarine spare parts at 0300 on the 5th. Shortly thereafter, she moved out; rested on the bottom until after dark; then surfaced to take on pasengers. At 1946, she got underway for the Netherlands East Indies.

She arrived at Sperabaja on 13 February. On the 21st, she left for Tjilatjap. whence she was ordered on to Australia. She reached Fremantle on 4 March and, two weeks later, again headed for the Indochina coast for her second war patrol. At the end of the month, she was diverted to Cebu to take on fuel and food for Corregidor. On the evening of 8 April, she arrived off that besieged base. At 2053, she moored alongside Pigeon, to which she transferred fuel; offloaded 7 tons of food; took on 21 passengers; and, at 2129, she got underway to resume her patrol.

 

She remained in the waters off southwestern Luzon and recommenced her patrol off the entrance to Subic Bay. On the 11th, she sighted several targets but was able to attack only one, a patrolling destroyer. At 1720, she fired three torpedoes. Twenty-nine seconds later, the first torpedo exploded halfway to the target. The second torpedo broached and circled abeam of the target. The destroyer avoided the third torpedo. Seadragon changed course and went to 200 feet to avoid the circling torpedo and the expected depth charging. None of the depth charges was close, but a second destroyer soon joined the first; spotted the submarine as she came up for a periscope observation; and turned on her. Seadragon again went deep, then cleared the area.

 

On the 12th, the submarine started south. On the 20th, she cleared Lombok Strait; and, on the 26th, she returned to Fremantle.

 

On her third patrol, 11 June to 2 August 1942, Seadragon returned to the South China Sea. Arriving in her assigned area on 27 June, she patrolled along the Singapore-Hong Kong routes to the end of the month; then shifted to the Cape Varella area. On the morning of 4 July, she fired a torpedo at the leader of a three-ship formation. The torpedo missed ahead; all three ships changed course toward Seadragon with the leader proceeding down the torpedo track firing her bow gun. Depth charges were dropped indiscriminately. Ten minutes later, the three had turned toward shore. Seadragon then shifted southward to intercept enemy traffic off Hon Lon Light.

 

A few hours later, she sighted two freighters and fired tubes 1 and 2 at the lead ship. Her No. 1 tube did not fire, and her No. 2 torepdo missed astern. Two more torpedoes were fired at the ships; but both missed. Enemy planes arrived on the scene soon afterward and, for over two hours, aerial depth charges in salvos of 2 and 3 were dropped. Despite water depth of 75 fathoms, submarines were visible at any depth against the light colored bottom.

 

Seadragon survived the close bombing and continued her patrol. During the next week, she attempted to close several ships, but was unable to attain attack positions. On the night of the 11th, her losing streak ended. Just prior to midnight, she sighted smoke and opened out to the westward to overtake the target. At 0156 on the 12th, she began her approach; and, 14 minutes later, she fired three torpedoes. Two hit, but the third missed astern. A merchantman, Hiyama Maru, began settling. By 0219, she had been abandoned. Seadragon submerged and resumed her patrol eight miles northeast of Cape Varella.

 

On the morning of the 13th, Seadragon torpedoed and sank her second victim of the patrol. Shinyo Maru was hit approximately 50 feet abaft the beam and settled immediately. Seadragon moved out of the area and hunted along the Haina Varella routes for a few days. On the 16th, she was back off Cape Varella; and, soon after 1030, she fired on a four-ship convoy. Five minutes later, the torpedoes exploded on the beach. The four ships turned toward Seadragon, and commenced firing their guns. Seadragon fired two more torpedoes and went deep. A few minutes later, she came to periscope depth. Only three ships remained on the surface. Hakodate Maru had been sunk.

 

On 20 July, Seadragon departed the South China Sea and made her way south to Australia. On 26 August, she departed her Australian base for her fourth war patrol and again set a course for the coast of Indochina. On 10 September, she moved through Apo East Pass. On the 11th, her progress into the South China Sea was delayed by an emergency appendectomy performed successfully by the pharmacist's mate. On the 12th, she arrived on station and commenced patrolling the steamer lanes west of Macclesfield Bank. At dusk on the 16th, she headed for Cape Varella.

 

Not until the 22d, however, while off Can Ranh Bay, was she able to gain a firing position on a suitable target. On that morning, she fired four torpedoes at a cruiser escorted by two destroyers. No explosions were heard, but her torpedoes were seen, and the enemy ships turned on Seadragon and delivered a “well executed depth charge attack.”

 

A week later, on the night of the 29th, the submarine tracked a five-ship convoy; and, at 0122 on the 30th, conducted a surface torpedo attack which damaged one ship. She then ran eastward to attain a position ahead of the convoy but was spotlighted by an escort which had shifted stations. Seadragon went deep; the escort dropped six depth charges and then rejoined the convoy. The submarine surfaced and attempted to make up for lost time. Three hours later, she had overheated her main motor cables and was forced to give up the chase.

 

On the evening of 3 October, Seadrayon departed the South China Sea and, five days later, commenced patrolling the approaches to Balikpapan. On the 10th, she attained a position for a stern tube shot on Shigitre Maru. The cargoman disappeared 47 seconds after the first explosion. On the 11th, the submarine patrolled off Capes William and Mandar. On the 12th, she was off Makassar City. On the 14th, she transited Lombok Strait; and, on the 20th, she returned to Fremantle.

 

Refit was started by Holland (AS-3) at Fremantle and completed by Griffin (AS-13) and Fulton (AS-11) at Brisbane. On 23 November, she departed the latter and headed for the Bismarck Archipelago for her fifth war patrol. On the 29th, she entered her area and commenced patrolling the Rabaul-Shortland routes. On 1 December, she closed the New Britain coast to intercept Buna traffic, and, during the next 10 days, conducted several unsuccessful approaches on enemy formations. On the morning of the 11th, she sighted a freighter with one escort rounding Cape St. George and fired two torpedoes at the merchantman. One hit under the main mast, damaging but not sinking the target. The escort delivered a depth charge attack, then took the damaged vessel under tow for Rabaul. Enemy planes prohibited Seadragon from delivering the coup de grace.

 

On the 21st, Seadragon sighted an enemy submarine, made her approach, and fired three torpedoes at the target. The first missed ahead. The second exploded about 18 seconds after firing. The third torpedo hit the enemy submarine. 1-4 sank with her bow vertical. The second torpedo explosion, however, had damaged Seadragon. The force of the explosion had knocked down the personnel in the forward torpedo room, and the torpedo in No. 1 tube, the outer door of which was open, was forced against the tail buffer. The counter effect forced the torpedo forward, shearing off the guide stud and tripping the starting lever. The outer door could not be closed. Depth control was lost. The torpedo was fired. Control was regained as the torpedo exploded on her port quarter.

 

On the 25th, Seadragn damaged another crewman, and, on the 26th, departed the area for Pearl Harbor where she arrived on 7 January 1943.

 

From Pearl Harbor, Seadragon continued on to the west coast. Between 16 January and 8 April, she underwent overhaul at Mare Island, receiving new batteries and radar and changing the position of her 3" mount from aft to a forward position. In mid-April, she sailed west again; and, on 9 May, she departed Pearl Harbor for her 6th war patrol.

 

On the 15th, Seadragon crossed the 180th Meridian and moved toward Micronesia. On the 19th, she commenced patrolling in the Carolines. On the 20th, she surprised and was in turn surprised by sighting a surfaced submarine on a parallel course. The other submarine submerged immediately. On the 22d, she took up station off the Truk Islands and for the next 11 days patrolled the sea lanes to the major enemyanchorage enclosed by Dublon, Fefan, and Uman islands. On 4 June, she departed Truk and moved eastward to reconnoiter Ponape, thence proceeded into the Marshalls to patrol the sealanes converging on Kwajalein. There, the enemy's omnipresent surface and aerial escorts inhibited hunting; but, on the 13th, Seadragon was able to damage a freighter. Four days later, she cleared the area; and, on the 21st, she arrived at Midway, whence she returned to Pearl Harbor for repairs to her steering gear.

 

From 18 July to 30 August, Seadragon conducted her 7th war patrol. Of the 44 days, 31 were spent on station near Wake and in the Marshalls where increased enemy air activity again hindered hunting and limited Scadragon's score to five freighters damaged. In mid-August, she reconnoitered Wotje; and, at the end of the month, she returned to Pearl Harbor.

 

On her 8th war patrol, 24 September to 5 November, Seadragon again returned to the Marshalls and spent 31 days hunting in the sea lanes to Kwajalein. Again Japanese antisubmarine measures hindered hunting; and, of the five ship contacts made, only two could be developed and only one attack was made. On 13 October, she damaged an enemy transport.

 

Seadragon's 9th war patrol, 14 December 1943 to 5 February 1944, took her back to the Carolines where she hunted enemy shipping on the Truk-Saipan route and damaged two, possibly three, cargomen.

 

Refit brought the replacement of Seadragon's “3 deck gun with a 4”; and, on 1 April, she cleared Pearl Harbor for the Japanese home islands for her 10th war patrol. On the 5th, she crossed the International Date Line. On the 15th, she entered Japanese waters. On the 16th, she moved past 6 Shima, and, that night, commenced patrolling off the Bungo Strait and Kii Channel entrances to the Inland Sea. On the morning of the 23d, she sighted four freighters, ecorted by three patrol boats, moving toward Shiono Misaki. She closed the convoy; fired on the third ship, the heaviest laden; then went deep and rigged for depth charging. The patrol boats moved toward Seadragon as Daiju Maru sank and, during the next two hours, delivered a 40 depth charge attack. Later that day, the submarine conducted an unsuccessful attack on a naval auxiliary; and, on the 26th, she moved out into the Tokyo-Manila shipping lanes where she damaged a freighter on the 27th.

 

On 28 April, she commenced patrolling the Nagoya-Saipan route. In May, she took station off the entrance to Sugura Wan and, on the 3d, shifted to the Tokyo-Guam-Saipan-Truk sea lanes. Two days later, she hunted enemy traffic at the entrance to Sagami Wan. On the 13th, she headed for Midway. On the 17th, she caught an armed trawler in a surface attack; set it afire with 4" gun salvos; then closed the target to take off the uniformed enemy crew. The surviving crew members refused to surrender, and Seadragon continued eastward. On the 21st, she crossed the 180th Meridian and stopped at Midway; thence got underway for Pearl Harbor, arriving on the 25th.

 

Reengined at Mare Island during the summer, Sea-dragon returned to Pearl Harbor on 7 September and departed on her 11th war patrol, a coordinated patrol with Shark (SS-314) and Black fish (SS-221), on the 23d. She arrived at Saipan to top off on 3 October. On the 4th, Shark and Blackfish continued on to the wolf-pack's assigned area in the northern China Sea. Sea-draffon, delayed by the need for repairs, did not depart until the 5th. On the 9th, she arrived off Batan Island, established contact with Shark and Blackfish, and took position in a scouting line in the pack's assigned area.

 

On the night of 21 October and the morning of the 22d, the group went after an enemy warship formation lead by a carrier. At 0615 on 24 October, Shark reported a contact, and Seadragon headed for the scene. At 0730, the contact was sighted through the high peri-scone, but it proved too distant. At 0920, Seadragon sighted three enemy merchantmen in a loose column with a torpedo boat destroyer and an airplane as escorts. At 1055, she fired four torpedoes at the lead freighter.

 

The first torpedo broached and ran erratic, alerting the escort which started for Seadragon. Seadragon rigged for depth charging. Soon thereafter, two torpedo explosions were heard; and, at 1101, the first of 8 depth charges was dropped. At 1154, Seadragon went to periscope depth. The escort was milling around picking up survivors four miles astern. The remaining merchant ships were ahead of the submarine and making only 2 or 3 knots. As Seadragon prepared to fire again, the destroyer rejoined the formation. At 1114, Sea-dragon fired four more torpedoes. Three hits were observed. The submarine's second target of the day sank in less than two minutes.

 

Seadragon went deep. Fifteen depth charges followed. At 1310, the submarine returned to periscope depth. The deck of the sole remaining freighter was crowded. The freighter was smoking heavily and moving slowly. The escort circled the freighter. At 1404, Seadragon fired. The first torpedo tore off the freighter's bow. The rest of the ship went under quickly. At 1405, the first of 25 depth charges was dropped.

 

Postwar examination of Japanese records identified the sunken ships as the cargo ship, Eiko Maru, and the passenger-cargomen, Taiten Maru, and Kokuryu Maru.

 

At 1858, Seadragon tried unsuccessfully to raise Shark. She had been sunk after attacking the contact of her 0615 transmission.

 

On 26 October, Seadragon headed toward Luzon. On the 27th and 28th, she searched for downed aviators; and, on the 29th, she was ordered to return to Midway.

 

Arriving at her destination on 8 November, she commenced refit; and, on 3 December, she headed west for her 12th war patrol. The patrol took her back into Japanese waters where she hunted enemy shipping and searched for downed aviators into January 1945. On the 10th, she moved into the Bonins, where she continued those two roles. On 19 January, she set a southerly course; and, on the 22d, she arrived at Guam to complete her last war patrol.

 

The next day, Seadragon continued on to Pearl Harbor, and, after refit, returned to California to Drovide training services to naval air units. In May, she was transferred back to the Atlantic Fleet and, for the final months of the war, provided training services at Guantanamo Bay and Key West. In September, she moved north to New London, thence to Boston where she was decommissioned on 15 November 1945. Less than four months later, on 8 February 1946, she wasrecommissioned to assist in the inactivation and preservation of submarines, including U-boats, at Hingham, Mass. On 29 October 1946, she was again decommissioned and berthed as a unit of the Atlantic Reserve Fleet where she remained until struck from the Navy list on 30 April 1948.

 

Seadragon earned 11 battle stars during World War II.
