USS Trout (SS-202)

USS Trout (SS-202) patch


The USS Trout (SS-202) was a Tambor-class World War II era submarine.

The namesake of the USS Trout is any of certain small, fresh-water fishes, highly esteemed by anglers for their gameness, their rich and finely flavored flesh, and their handsome (usually mottled or speckled) coloration.

The radio call sign of the USS Trout was: NAN - ABLE - XRAY - CHARLIE.

On February 8, 1944, the Trout, captained by Lieutenant Commander Albert H. Clark, left Pearl Harbor for her eleventh and final war patrol.  After fueling at Midway Island on the 16th, she headed for the East China Sea, and was never heard from again.  The Trout was expected to be back at Midway by about April 7, 1944.  By April 17th she had failed to appear and she was reported presumed lost.  The official announcement of the Trout's loss was made on July 22, 1944. 1

Navy Department Communiqué No. 532, July 22, 1944

1. The submarines USS Trout and USS Tullibee are overdue from patrol and must be presumed to be lost.

2. The next of kin of casualties of the Trout and Tullibee have been so notified.


Loss Possibility

The Trout probably met her end on February 29, 1944, at the geographic location 22°-40'N, 131°-45'E, which is southeast of Okinawa in the Philippine Sea.  Japanese records reviewed after the war revealed that one of their convoys was attacked by a submarine on that date near that position.  The submarine sank the 9,245-ton cargo vessel Sakito Maru, and damaged the passenger-cargo vessel Aki Maru and the transport Tozan Maru.  The IJN destroyer Asashimo detected the submarine and delivered a counterattack, dropping twenty depth charges.  The attack brought up a lot of oil to the surface and a loud underwater explosion was heard.  The Trout was the only American submarine operating in that area at that time. 2


A list of the personnel lost with the Trout is maintained at http://www.oneternalpatrol.com/uss-trout-202.htm.

The Trout received eleven battle stars for her World War II service and the Presidential Unit Citation for her second, third, and fifth patrols.  Her Alden-McDonald score is nineteen vessels sunk for 43,709 tons and eleven vessels damaged for 104,333 tons.  The SORG score for the Trout is sixteen vessels sunk for 97,000 tons and seven vessels damaged for 83,000 tons.  She was scored by JANAC for sinking 37,144 tons in twelve enemy vessels, including the Japanese submarine I-182.  However, according to Vernon J. Miller, "There is no question that Trout did encounter an enemy submarine, but no sinking was achieved.  The identification of the submarine remains unknown, but it definitely was not I-182, which, at the time of the attack, was operating off the New Hebrides." 3

4.  The Nisshin Maru and the Trout crossed paths twice, and the tanker was damaged by the submarine both times.  The first attack occurred on April 10, 1942, during the Trout's third patrol.  The second attack happened during the Trout's seventh war patrol.

5.  During her eighth war patrol, on April 7, 1943, the Trout laid twenty-three Mark 12 mines off Borneo in the South China Sea.  On May 26, 1943, the Japanese-controlled oil tanker Palembang Maru hit one of the mines at 02°-02'N, 109°-13'E, was damaged and towed to Singapore, where she was under repair until November 1944.
