USS Trigger (SS-237) was a Gato-class submarine, the first ship of the United States Navy to be named for the triggerfish.
Construction
Trigger's keel was laid down on 1 February 1941 at
Battle of Midway
The submarine sailed for
First patrol: June–August 1942
On 26 June, Trigger got underway for the Aleutian Islands to patrol an area west of Cape Wrangell, Attu Island. She encountered six destroyers, three freighters and a patrol boat, attacking none, before calling at Dutch Harbor on 8 August en route back to Hawaii.
Second patrol: September–November 1942
Roy S. Benson assumed command before Trigger began her second war patrol, conducted from 23 September to 8 November in "Empire Waters" (the seas immediately surrounding Japan). In the early morning hours of 5 October, the submarine sighted smoke on the horizon and headed for it. A vessel soon appeared, coming toward the submarine. As the target approached, the submarine identified it as a small ship. Trigger then surfaced and manned her machine guns. As the target neared, however, the submarine learned that the Japanese ship was larger than initially thought. Enemy shells soon began exploding close to Trigger, and the 4,000 ton ship turned and accelerated in an attempt to ram the submarine. Trigger barely avoided a collision as she submerged for an attack; she launched two torpedoes and heard one hit. She then surfaced and gave chase, only to have the target again open fire. The submarine missed with three more torpedoes and then discontinued the pursuit.
Before dawn on the morning of 17 October, Trigger made a surface attack on a
Near midnight of 20 October, Trigger fired a spread of four torpedoes from very close range, 900 yards (820 m), in a surface attack on a 10,000-ton
Third patrol: December 1942–January 1943
From 3 December 1942 to 22 January 1943, the submarine conducted a combined minelaying and offensive patrol, again in waters surrounding the Japanese home islands. On 20 December, she began planting a minefield off
On 22 December, Trigger sighted a ship approaching from Uraga and made a surface attack. A spread of three torpedoes produced one hit forward of the bridge, and the target started to settle by the bow. The submarine fired one more torpedo into the ship and, when last seen, Teifuku Maru was awash forward with her screws nearly out of the water. On 31 December 1942, she attacked a cargo ship loaded with planes. Trigger fired three torpedoes from extremely close range 700 yards (640 m), and watched two hit. The target began to list to starboard and was down by the bow. Sound reported a heavy secondary explosion. The submarine came up to periscope level and saw the freighter with her stern high out of the water and a destroyer approaching. Trigger went deep and when she next came up for a look, there was nothing to be seen. (The sinking was not confirmed by JANAC postwar.)
On 10 January 1943, a Japanese destroyer approached Trigger, and the submarine fired three torpedoes from 1,600 yards (1,500 m). One hit under the well deck and folded the destroyer's forecastle up at a 45° angle, and another hit the target's stern. Soon, the Minekaze-class destroyer Okikaze sank on an even keel.
Fourth patrol: February–April 1943
Trigger stood out of Midway on 13 February to patrol off the
That night, the submarine fired six torpedoes at a ship that was being towed by a smaller freighter. Five of the torpedoes missed, and the sixth made a circular run and passed over the submarine's engine room. A shaken crew broke off the attack.
On 20 March, the submarine launched three torpedoes at the lead ship in a convoy of four cargo ships. One hit caused the target to list 10° to port and stop, but it soon got underway and rejoined the convoy. Trigger terminated the patrol at the Submarine Base, Pearl Harbor, on 6 April.
Fifth patrol: April–June 1943
Between 30 April and 22 June, the submarine made a patrol which returned her to Empire waters. Directed by an Ultra from Pearl Harbor, Trigger lay athwart the projected track of Admiral Koga's task force returning from Truk. Koga's force came in sight the morning of 22 May, but zigged away, out of range, "a bitter disappointment".[7] On 28 May, Trigger contacted two freighters off Iro Saki and fired three torpedoes at the larger. One hit aft. When last seen, the ship was down by the stern. The next day, the submarine fired a spread of three torpedoes at a small cargo ship. Two missed and the third exploded prematurely. She then fired a fourth torpedo, which apparently hit but failed to explode.
On 1 June, the submarine was searching for Japanese shipping off Sagami Nada when she sighted two columns of smoke. She closed the range toward a firing position, made out two cargo ships, and fired a spread of three torpedoes at each target. Hit in her stern, the lead ship, Noborikawa Maru, sank immediately. The second ship saw the torpedo wakes, turned and passed between them. Trigger then fired a torpedo at the oncoming ship; if the torpedo reached the target, it failed to explode.
Again alerted by Ultra, on 10 June (her last day on station), Trigger sighted an
Sixth patrol: September 1943
On 1 September, after a yard overhaul, Trigger (now in the charge of Commander Robert "Dusty" Dornin) was ready to begin her sixth war patrol. The patrol took her into the East China Sea, off the China coast, north of Formosa. On 17 September, she made two hits on a Japanese freighter, one aft and one on the bow, but both torpedoes proved to be duds. The next day, she again contacted the same ship and launched four torpedoes at her. One struck Yowa Maru, and the 6,435-ton cargo ship slid beneath the waves.
21 September was Trigger's best day. She was patrolling some 30 miles (48 km) north of the
Seventh patrol: October–December 1943
The East China Sea and Yellow Sea were Trigger's objective for her seventh patrol. She stood out of Midway on 22 October and proceeded to her patrol area. At 22:00 on 1 November, she sighted a convoy that was steaming in two columns. When a ship in the nearer column overlapped one in the more distant group, Trigger fired a spread of three torpedoes at them. One torpedo struck the nearer freighter in the bow and one hit the farther ship amidships. The submarine saw the nearer ship go down by the bow, before she herself was forced to go deep where she was severely depth-charged by two escorts.
Early the next morning (2 November), Trigger launched three torpedoes at a freighter and scored one hit. At 00:50, she attacked the ship again with another three-torpedo spread. Two of them hit forward, and Yawata Maru went down, bow first, in a vertical plunge. Two hours and 25 minutes later, Trigger launched three torpedoes at a 7,148-ton transport. All hit, and Delagoa Maru disintegrated. On 5 November, the submarine attacked a convoy of three cargo ships protected by one destroyer and two planes. Trigger fired three bow tubes at the second ship in the convoy and one bow tube at the third before going deep to avoid the escort which dropped 20 depth charges. Thinking she was clear, the submarine came to periscope depth and was greeted by five near bomb misses.
On 13 November, Trigger made a submerged approach on a convoy of nine merchantmen and four escorts. After the Japanese ships zigged, the submarine found herself between two columns of ships, but Trigger had no torpedoes remaining in her bow tubes. She emptied her stern tubes at the last and biggest ship, believed to be a transport, from a
Eighth patrol: January–February 1944
Trigger stood out to sea on New Year's Day 1944 to begin her eighth war patrol, this time in the Truk-Guam shipping lanes. On 27 January, she sighted the conning tower of an Ro-class submarine dead ahead. Trigger set up to fire a bow shot from 800 yards (730 m). She came to periscope depth and saw the Japanese submarine, then less than 100 yards (91 m) away, was preparing to attack. Trigger submerged to 150 feet (50 m), expecting a torpedo at any minute, but sound heard no torpedo screws. She came up to periscope depth and saw the Japanese periscope so she decided to make an end around. When Trigger returned to periscope depth, the enemy had disappeared.
Four days later, she contacted a convoy of three ships accompanied by two Fubuki-class destroyers. The submarine scored two hits on the coastal minelayer Nasami, which disappeared in a cloud of smoke and debris. The nearer destroyer began closing the range, and Trigger missed it with four aft tubes. She caught up with the convoy again and fired five torpedoes at the last ship. Two hits produced flames that reached mast height and several secondary explosions that marked the end of the 11,933-ton converted submarine tender Yasukuni Maru. Over three weeks later, the submarine terminated the patrol when she arrived at Pearl Harbor on 23 February.
Ninth patrol: March–May 1944
On 23 March, Trigger (now in the able hands of Commander
Trigger met submarine USS Tang on 14 April and exchanged information by line gun. The next day, Trigger's executive officer went on board Tang by a rubber boat, to borrow an air compressor part and to make plans for a coordinated search and attack. On 18 April, Tang's executive officer delivered spare parts for the air compressor to Trigger, and she continued on patrol.
Shortly before midnight on 26 April, Trigger contacted a convoy of six ships off the eastern Palaus. She fired six torpedoes, from 2,400 yards (2,200 m), at four ships that were closely bunched and overlapping. Four hits were seen and heard, with a big explosion on each ship. Suddenly, a terrific explosion blew up one of the closer ships. One of the more distant ships stood straight up on her bow and sank immediately. At six minutes after midnight, Trigger launched three torpedoes at another group of ships and heard one timed explosion. At 01:57, she launched four torpedoes at a damaged cargo ship and two at an escort. The cargo ship received two more hits. Five minutes later, the submarine fired three stern tubes at a group of three escorts, and the middle one disappeared in a cloud of smoke. During the attack, Trigger sank the 11,739-ton passenger/cargo ship Miike Maru and heavily damaged the destroyer escort Kasado, the 9,467-ton cargo ship
Tenth patrol: September–November 1944
On 24 September, Trigger got underway to take station off the east coast of Formosa and perform life guard patrol for bomber strikes due on 12 October. The morning of the strikes, she rescued a pilot from aircraft carrier USS Bunker Hill whose burning plane had crash-landed nearby. On 19 October, as the invasion of the Philippines was about to begin, Trigger contacted a convoy of two Takao-class heavy cruisers, one Nagara-class cruiser, two other light cruisers, and several destroyers with air cover. Trigger had no chance to fire but reported the contact. On 30 October, she launched four torpedoes at a tanker but missed. She then fired another four from her stern tubes and heard one hit the target before running up the periscope to watch the other three blow off part of the stern, but the ship did not sink. Trigger went deep as 78 depth charges were rained down on her within the next hour, but caused no damage. The damaged 10,021-ton tanker Takane Maru was later sunk by submarines USS Salmon and USS Sterlet. The next morning, Trigger received word from Salmon that she had been heavily damaged by depth charges and was unable to submerge. Trigger rendezvoused with Salmon that night and was joined by USS Silversides and Sterlet to escort the damaged submarine to Saipan. They were provided with air cover from the Mariana Islands and arrived at Tanapag Harbor on 3 November. A week later, Trigger departed with six other submarines but was ordered to discontinue her patrol on 17 November and returned to Guam.
Eleventh patrol: December 1944–February 1945
On 28 December 1944, Trigger headed for the Bungo Suido-
On 29 January, the submarine made radar contact from 23,000 yards (21,000 m) on a large convoy with six escorts and well covered by aircraft. As she closed, the moon came out bright and clear. An enemy bomber turned and started in as radar picked up another plane coming in astern at 5,000 yards (4,600 m). The submarine went deep, and the convoy slowly pulled away. The next day, the ship was ordered to terminate her patrol, and she returned to Guam on 3 February.
Twelfth patrol: March 1945
