The first '''USS ''Trepang'' (SS/AGSS-412)''' was a [[Balao-class submarine|''Balao''-class]] [[submarine]] in the [[United States Navy]]. She was named after the ''trepang'' (or ''trīpang''), an [[Indonesian language|Indonesian]] name for a marine animal called a "[[sea slug]]" or a "[[sea cucumber]]," having a long, tough, muscular body and found in the [[coral reef]]s of the [[East Indies]].

==Construction and commissioning==
When the contract to build ''Trepang'' was awarded to [[Mare Island Navy Yard]] in [[Vallejo, California|Vallejo]], [[California]], SS-412 was to be named ''Senorita'', which would have made her the only U.S. Navy ship to be named for the ''[[Oxyjulis|señorita]]'', a brilliantly colored fish found along the California coast. She was renamed ''Trepang'' on 24 September 1942, and her [[keel]] was [[Keel-laying|laid down]] on 25 June 1943. She was [[Ceremonial ship launching|launched]] on 23 March 1944 sponsored by Mrs. Jane Andre Davenport (''née'' Gorham), the wife of ''Trepang''′s prospective [[commanding officer]], [[Commander (United States)|Commander]] [[Roy M. Davenport|Roy Milton Davenport]], and [[ship commissioning|commissioned]] on 22 May 1944 with Commander Davenport — already a three-time [[Navy Cross (United States)|Navy Cross]] winner — in command.

==Service history==
===World War II===
====May–September 1944====
Following [[Shakedown (testing)|shakedown]] at [[San Diego]], California, ''Trepang'' departed San Diego on 15 August 1944 and proceeded to [[Pearl Harbor]], [[Hawaii]]. where her crew trained and prepared the ship for combat.

==== First war patrol: September – October 1944 ====
Setting out from Pearl Harbor on 13 September 1944 for her first war patrol, ''Trepang'' prowled the waters south of [[Honshū]], the largest and most important of Japan's home islands. She remained below during daylight hours and came up after dark to get a better view as she recharged her batteries and filled up with fresh air. On the night of 30 September, ''Trepang'' spotted a fast [[convoy]] departing [[Tokyo Bay]]. The submarine gave chase and closed in on a group of ships which included two large [[Tanker (ship)|tanker]]s, a small freighter, and an escort. The submarine fired an overlapping spread of torpedoes which struck the freighter, 750-ton ''Takunan Maru'', and sent her to the bottom.

On 10 October, ''Trepang'' attacked her second convoy, which consisted of a pair of tankers and a single escort. Although the submarine claimed a "kill", a postwar assessment of the action did not credit her with a sinking. The following day, the error was reversed. The submarine launched four torpedoes at another Japanese ship, and her commanding officer recorded that all of the "fish" had missed. This time, however, postwar accounting credited ''Trepang'' with the destruction of the 1,000-ton ''Transport Number 105''.

On 12 October, the submarine cruised some {{convert|12|mi|km}} southwest of the entrance to Tokyo Bay. Soon after she came to the surface, and her [[radar]] swept the surrounding seas, four pips showed themselves on the phosphorescent screen—two large and two small—which were identified as two [[battleship]]s and two [[destroyer]]s.

Despite the fact that the phosphorescent waters would make his submarine stand out starkly in the night, Davenport closed at flank speed and fired a full spread of six torpedoes. The "fish" sped through the water toward their targets. He claimed success when explosions rumbled across the water, and flames lit up the night. Davenport turned the submarine to present her stern tubes to the enemy and loosed four more torpedoes. These all missed.

Davenport's gallant and skillfully pressed attacks earned him his fourth [[Navy Cross (United States)|Navy Cross]]. He felt that he had damaged a {{sclass|Fusō|battleship|2}} and had sunk a [[destroyer]], but a study of Japanese records after the war did not verify either claim. [In fact the Trepang had damaged the [[Japanese destroyer Fuyutsuki]] off Omaesuki]<ref>[https://archive.org/stream/TheOfficialChronologyOfTheUSNavyInWorldWarII#page/n553/mode/2up/search/Trepang Official Naval Chronology 12 October 1944]</ref>

Her supply of torpedoes exhausted, ''Trepang'' cleared the area and headed for the [[Marshall Islands]]. She reached [[Majuro]] on 23 October for voyage repairs alongside submarine tender {{USS|Bushnell|AS-15}} and brief training.

==== Second war patrol: November – December 1944 ====
On 16 November, ''Trepang'' got underway for the [[Philippine Islands]] leading a "[[Wolfpack (naval tactic)|wolfpack]]" which also included sister ships {{USS|Segundo|SS-398}} and {{USS|Razorback|SS-394}}. The wolfpack's nickname was "ROY'S RANGERS" as ''Trepang''{{'}}s own commanding officer, Roy M Davenport, was the officer in charge of the pack.

The weather was dark, windy, and rough on 6 December as ''Trepang''{{'}}s conning tower broke the surface after a day's submerged inshore patrol off [[Luzon]]. While shifting course toward deeper water, she detected a group of ships approaching from the northward. Upon closing to investigate, ''Trepang'' counted seven large ships and three escorts in the convoy which slowly approached the Philippines.

''Trepang'' radioed news of her "find" to her packmaster and then submerged. The submarine shot straight and true, sending freighter ''Banshu Maru Number 31'' and cargo ship ''Jinyo Maru'' to the bottom in quick succession and damaging a third vessel, ''Fukuyo Maru''. However, as ''Trepang'' came about to administer the coup de grace to ''Fukuyo Maru'', the third cargo ship obligingly blew up and sank. Meanwhile, as ''Segundo'' and ''Razorback'' arrived on the scene, ''Trepang'' fired all of her remaining torpedoes at a fourth ship which, she reported, blew up and sank soon thereafter. However, this fourth sinking was not confirmed by Japanese records. In the meantime, the other two American submarines were trying to finish off the fleeing remnants of the shattered convoy and managed to sink two ships, one with the aid of American naval aircraft. ''Trepang'', now out of torpedoes, sped back to Pearl Harbor, arriving before [[Christmas]].

Following this war patrol, Davenport, one of the most highly decorated submariners of the war, left ''Trepang'' for shore duty as an instructor at the [[United States Naval Academy]].

==== Third war patrol: January – March 1945 ====
Again sailing for Honshū, ''Trepang''—now under Cmdr. Allen R. Faust—teamed up with submarines
{{USS|Piper|SS-409}}, {{USS|Pomfret|SS-391}}, {{USS|Bowfin|SS-287}}, and {{USS|Sterlet|SS-392}}, known as "Mac's Mops," on an anti-picket boat sweep past [[Nanpō Islands]], the eastern island chain south of [[Tokyo]], to clear the sea lanes for the [[aircraft carrier]]s of [[Task Force 58]] which in turn was about to strike the Japanese home islands to neutralize them during the assault on the strategic island of [[Iwo Jima]]. ''Trepang'' encountered no worthwhile targets during the patrol and had to settle for performing lifeguard duty for [[aircraft carrier]] assaults on Tokyo. On 24 February 1945, the submarine sank the 875-ton freighter ''Usuki Maru'' and blew the bow off another small coastal vessel. While maneuvering to finish off the crippled ship, several antisubmarine vessels appeared on the scene from behind a nearby headland and converged on the fleet boat. ''Trepang'' dove deep as the Japanese subjected her to a seven-hour [[depth charge]] barrage. On 14 March, ''Trepang'' sank the IJN Guardboat ''Kaiko Maru'' off Inubosaki.<ref>[https://archive.org/stream/TheOfficialChronologyOfTheUSNavyInWorldWarII#page/n637/mode/2up/search/Trepang Official Navy Chronology 14 March 1945]</ref> On 17 March, ''Trepang'' attacked and sank 117-ton picket boat ''Tsukiura Maru'' (a converted [[bonito]] and [[Tuna|tunny]] [[fishing boat]]) off [[Tori-shima (Izu Islands)|Torishima]].<ref>The Maru Special, ''Japanese Naval Vessels No. 53, "Japanese support vessels"'', {{cite web |url=http://www.kojinsha.co.jp/ |title=Ushio Shobō}} (1981), p. 62
</ref>

==== Fourth war patrol: April – May 1945 ====
Following her return to [[Guam]] in March, ''Trepang'' headed for the [[Yellow Sea]], a "hazardous duty" area due to its vast stretches of shallow water. Despite the danger, the submarine performed well, sinking the 1000-ton landing craft ''Transport Number 146'' on 28 April; the 4667-ton, heavily laden freighter, ''Miho Maru'' two days later; and ''Minesweeper Number 20'' which blew sky-high with a hit on her magazine on 4 May. In addition, the submarine surfaced to shell a junk with a load of lumber. The sole member of this victim's crew, a Korean, understood little sign language, and looked to be of little value for intelligence purposes, so he was put back on board his barely seaworthy craft, with tools and food, and sent on his way.<ref>[http://navsource.org/archives/08/pdf/0841221.pdf The official summary reports that the submarine just destroyed his lumber cargo but not his barely seaworthy vessel]</ref> Leaving the Yellow Sea, ''Trepang'' did a short tour of lifeguarding for [[B-25 Mitchell]] strikes on [[Shanghai]], [[China]], and for the continuing series of [[B-29 Superfortress]] raids on Tokyo, before she returned to Guam.

==== Fifth war patrol: June – July 1945 ====
''Trepang''{{'}}s fifth war patrol was divided into two parts—the first saw the ship operating in a lifeguard capacity while the second gave her a more offensive role off northeastern Honshū and eastern [[Hokkaidō]]. In the former role, she arrived on station to the southeast of Tokyo Bay. On 22 June 1945, she was on the surface in the [[Pacific Ocean]] {{convert|20|nmi|0}} southeast of [[Daiozaki Light]] on the coast of [[Honshu]], [[Japan]], when a flight of seven [[United States Army Air Forces]] [[Boeing B-29 Superfortress|B-29 Superfortress]] [[bomber]]s jettisoned three [[Aerial bomb|bombs]] which straddled her, one landing {{convert|1,000|yd|sigfig=2}} off her [[Port and starboard|port]] [[Bow (ship)|bow]] and two landing {{convert|2,000|yd|sigfig=2}} off her [[Port and starboard|starboard]] quarter. She suffered no damage or casualties.<ref>Hinman & Campbell, p. 305.</ref>

Having experienced two previous tours of lifeguarding, ''Trepang''{{'}}s men otherwise expected a series of long dull days, spent moving in circles, squares, or triangles to break the monotony. However, shortly before 12:00 on 24 June 1945, her first day of lifeguard duty, lookouts spotted a blossoming parachute overhead and soon saw the splash of a crashed [[North American P-51 Mustang|P-51 Mustang]] fighter damaged while escorting Superfortresses to Tokyo. ''Trepang'' bent on full power and soon picked up the downed aviator, [[Second Lieutenant]] Lamar Christian, [[United States Army Air Forces|USAAF]], safe and sound. During the maneuver, another Mustang, piloted by [[First Lieutenant]] Frank Ayres, USAAF, radioed that it, too, was in trouble; and the pilot requested permission to bail out. ''Trepang'' replied telling Ayres to "be patient" until the first rescue was complete. Ayres circled the submarine until Christian was safely on board the submarine. Ayres then executed a perfect jump and landed some {{convert|400|yd|sigfig=2}} away from ''Trepang'' and was soon hauled on board.

On 27 June 1945, ''Trepang'' turned the two airmen over to the submarine {{USS|Tigrone|SS-419}} which was on her way home with 30 other aviators already on board. In the middle of the transfer, the submarines picked up a radio message from a "Boxkite" (rescue search plane) that the surviving crew of Superfortress 44-70109 of the [[504th Bomb Group]],{{citation needed|date=February 2023}} downed on 26 June 1945, was floating a mere {{convert|7|nmi}} from the Japanese seaport of [[Nagoya]]. Accompanied by her [[sister ship]] {{USS|Springer|SS-414}} which had also been discharging passengers to ''Tigrone'', ''Trepang'' surged ahead.

The two submarines raced to save the Superfortress's crew. ''Trepang'' put on full speed and arrived on the scene first. She found eight survivors in four groups of rafts, spread over about {{convert|4|nmi}} of ocean. By the time ''Springer'' arrived on the scene, ''Trepang'' had picked up seven of the fliers.  ''Springer'' picked up the last man.<ref>[http://navsource.org/archives/08/pdf/0841221.pdf Summary of Ships History]</ref> Four other members of the Superfortress crew did not survive, either having been either trapped in the plane, killed when their burning [[parachute]]s failed, or gone missing.{{citation needed|date=February 2023}}

On 30 June 1945<ref>[http://www.combinedfleet.com/sorg.php?q=412 Combined Fleet Summary USS Trepang]</ref> En route to a rendezvous with submarine {{USS|Devilfish|SS-292}}, ''Trepang'' sighted a small, troop-laden freighter — described in an official ship's history both as a 492-[[displacement ton]] [[minesweeper]] and a 600-[[gross register ton]] [[cargo ship]], in either case armed with two 37-millimeter guns — and sank the ship with her deck guns. A dozen or so Japanese soldiers from the flaming vessel refused to be picked up and taken prisoner and so were left to drown.<ref>[http://navsource.org/archives/08/pdf/0841221.pdf Official summary of ships history pp. 3 and 9 at Navsource.org]</ref>

Subsequently patrolling off the eastern coast of [[Honshū]], ''Trepang'' went scoreless until 7 July 1945 when she spotted a coastal convoy of three ships. She torpedoed and sank the lead ship—''Koun Maru Number Two''—but the other vessels conducted evasive action and sped away from the scene at full speed. Heading to seaward, ''Trepang'' suddenly shuddered under the impact of two depth-charge explosions. A solitary Japanese plane had spotted ''Trepang''{{'}}s shadow in the shallow waters and had attacked her with depth charges. All missed their mark.

Given another lifeguarding assignment, ''Trepang'' stood on the alert to pick up possible downed airmen from British and American [[aircraft carrier]] strikes on the [[Japanese archipelago|Japanese Home Islands]]. During this tour in July 1945, she rescued one pilot, [[Lieutenant, junior grade]], Bill Kingston, [[United States Naval Reserve|USNR]]. In addition, on 14 July 1945, she witnessed a [[shore bombardment]] conducted by three [[battleship]]s and a [[heavy cruiser]] against [[Kamaishi, Iwate|Kamaishi]], Japan, during which, reportedly, ''Trepang'' sank a 100-gross register ton [[Lugger]] with her [[deck gun]].<ref>[http://www.combinedfleet.com/sorg.php?q=412 Combined Fleet]</ref>

By now, the war was moving fast, and ''Trepang'' returned to Pearl Harbor for a refit. There, she watched the tumbling succession of staggering headlines—first the [[atomic bomb]]s on [[Hiroshima]] and [[Nagasaki, Nagasaki|Nagasaki]], the [[Soviet Union]]'s entry into the Far Eastern War, Japan's tentative acceptance of surrender terms, and finally, on 15 August, peace at last.

=== Post-World War II ===
After completion of her refit, ''Trepang'' departed Pearl Harbor and arrived at San Diego on 3 September 1945. [[Ship decommissioning|Decommissioned]] on 27 June 1946 and placed in [[Reserve fleet|reserve]] at Vallejo, California, at the [[Mare Island Naval Shipyard]], ''Trepang'' remained in reserve until 1967. She was redesignated as an [[Auxiliary ship|auxiliary]] submarine and given the [[hull classification symbol]] '''AGSS-412''' on 11 June 1962.

==Disposal==
Struck from the [[Naval Vessel Register]] on 30 June 1967<ref name="FriedmanSubs1-dates"/> ''Trepang'' was authorized for disposal on 22 December 1967. She was sunk as a [[Target ship|target]] in the [[Pacific Ocean]] off [[Southern California]] during Exercise "Strike Ex 4-69" on 16 September 1969 by the combined gunfire of the destroyers {{USS|Henderson|DD-785}} and {{USS|Fechteler|DD-870}}.<ref name="Register"/>

==Honors and awards==
''Trepang'' received five [[battle star]]s for [[World War II]] service and a [[Navy Unit Commendation]].

==In media==
While in reserve, ''Trepang'' appeared in "Dennis at Boot Camp," the ninth episode of the fourth season of the American [[situation comedy]] ''[[Dennis the Menace (1959 TV series)|Dennis the Menace]]'', first broadcast in the [[United States]] on 25 November 1962.<ref>{{Cite web|url=https://www.imdb.com/title/tt0557922/plotsummary?ref_=tt_ov_pl|title = "Dennis the Menace" Dennis at Boot Camp (TV Episode 1962) - IMDb| website=[[IMDb]] }}</ref>
