USS ''Tench'' (SS/AGSS-417), the lead ship of her class of submarine, was the only ship of the United States Navy to be named for the tench. Her keel was laid down on 1 April 1944 at the Portsmouth Navy Yard. She was launched on 7 July 1944, sponsored by Claudia Alta Johnson, the wife of Rep. Lyndon Baines Johnson, and commissioned on 6 October 1944 with Commander William B. "Barney"〔Blair, Clay, Jr. ''Silent Victory'' (Philadelphia: Lippincott, 1975), p.1059.〕 Sieglaff〔Sieglaff, as Duty Officer in ''Tautog'' during the attack on Pearl Harbor, had destroyed the first Japanese aircraft by an American submarine. Blair, p.99〕 in command. ==First War Patrol== After completing trials and shakedown out of New London, Connecticut, ''Tench'' departed that port on 20 December for duty in the Pacific. Following brief pauses for training at Key West, Florida, and in the Panama Canal Zone, she reached Pearl Harbor during the latter part of January 1945. An additional training period followed her arrival in Oahu, but only a brief one. On 7 February, she stood out of Pearl Harbor, bound for her first war patrol. After a stop at Saipan for fuel, ''Tench'' returned to sea in company with , , and —the other three submarines in the coordinated attack group (colloquially called a "wolf pack") to which she was assigned. They left Saipan on 27 February and headed for their assigned patrol area which began in the region of the East China Sea southwest of Kyūshū and extended north into the Yellow Sea. On the night of 6 March and 7 March, ''Tench'' passed through the Colnett Strait south of Yoku Shima and into the East China Sea. The four submarines rotated patrol, weather-reporting, photographic-reconnaissance, and lifeguard duties. On 18 March, ''Tench'' received orders to take up lifeguard station off the western coast of Kyūshū during Fifth Fleet carrier air raids on Nagasaki. Just before the noon watch came on duty, the submarine got word of a dye marker sighting (presumably evidence of a downed American aviator) sighted by friendly aircraft in a bay on the coast of Kyūshū near the town of Akune. Under the protective cover of F6F Hellcat fighters, ''Tench'' threaded her way cautiously into the shallow waters of the bay. Just after she discovered the "sighting" had been the result of a reflection of a shoal spot, she received a severe fright. Caught in waters too shallow for her to dive, she proceeded almost helplessly on the surface while a large flight of aircraft approached her from astern. Fortunately the planes proved to be additional Fifth Fleet bombers returning from Nagasaki. ''Tench'' stood offshore and watched while they loosed their remaining bombs on installations near Akune: a railroad bridge, a fuel dump, and a factory. The remainder of March proved relatively unproductive. In the absence of targets worthy of torpedoes, the submarine contented herself with the destruction of floating mines and with the sinking of two tiny trawlers on 28 March. Early on 3 April, an enemy bomber forced her to dive, and she ran submerged for the remainder of the day. That evening, she surfaced once again and soon made radar contact with a good-sized target. The fact the enemy ship carried radar, coupled with the appearance of a second target larger than the first, indicated she was some type of warship escorting a merchantman. Darkness and fog dictated a surface attack. ''Tench''’s report claims the target, the large cargoman, took one torpedo hit and erupted in a splendid pyrotechnic display. Unfortunately, there is no evidence to confirm the kill.〔The JANAC accounting postwar was notoriously unreliable, with Japanese records in chaos.〕 ''Tench''’s first war patrol had begun soon after the invasion of Iwo Jima and continued past the landings on Okinawa. American planners had foreseen the possibility of Japan's attempting to strike back at the Allied forces with what remained of the Imperial surface fleet. They therefore stationed a picket line of submarines off Japan to serve as an early warning system. ''Tench'' received orders to join this patrol line before concluding her war patrol. She was on station off the western coast of the Japanese home islands when the ''Yamato'' task force sortied on 6 April to contest the Okinawa landings. ''Tench'' did not make a sighting, since ''Yamato'' sortied from the Bungo Suido. That station was assigned , which raised the alarm; the picket line was disbanded, and each submarine turned to its own individual mission. In accordance to orders, ''Tench'' cleared the area for an air-sea rescue sweep of the East China Sea before ending her patrol. On 8 April, she picked up the pilot and radioman from a dive-bomber from and then headed for Guam where she arrived on 14 April. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「USS Tench (SS-417)」の詳細全文を読む スポンサード リンク
