USS ''Mahan'' (DD-364) was the lead ship of the United States Navy's s. The ship was named for Rear Admiral Alfred Thayer Mahan, a 19th-century naval historian and strategic theorist. Her design ushered in major advances over traditional destroyers. Among them were a third set of quadruple torpedo tubes, protective gun shelters, and emergency diesel generators. Along with a steam propulsion system that was simpler and more efficient to operate. ''Mahan'' began her service in 1936. She was first assigned to the US Atlantic Fleet and then transferred to Pearl Harbor in 1937. When the Japanese attacked Pearl Harbor on 7 December 1941, ''Mahan'' was at sea with Task Force 12. Their mission to Midway Island was aborted to participate in the post-attack search for the enemy strike force. Unable to locate them, the task force returned to Pearl Harbor. Early in World War II, ''Mahan'' took part in raids on the Marshall and Gilbert Islands. In the Battle of the Santa Cruz Islands, Admirals Chester Nimitz and William Halsey commended the destroyer group (of which ''Mahan'' was a member) for a stellar effort in screening the aircraft carriers and against heavy odds. During the New Guinea campaign to take the northeast coast from the Japanese, ''Mahan'' was engaged in the amphibious landings at Salamaua, Lae, and Finschhafen. She participated in landings at Arawe and Borgen Bay (near Cape Gloucester), New Britain, and provided support for the troop landing at Los Negros Island in the Admiralty Islands. Late in the Pacific War, the Japanese kamikaze relentlessly plagued US Naval operations. On 7 December 1944, a group of suicide aircraft overwhelmed and disabled ''Mahan'' at Ormoc Bay, Leyte, in the Philippine Islands. On fire and exploding, the ship was abandoned, and a US destroyer sank her with torpedoes and gunfire. ==Characteristics== ''Mahan'' displaced at standard load and at deep load. The ship's overall length was , the beam was and her draft was . She was powered by two General Electric geared steam turbines that developed a total of for a maximum speed of . Four Babcock and Wilcox or four Foster Wheeler water-tube boilers generated the superheated steam needed for the turbines. ''Mahan'' carried a maximum of of fuel oil, with a range of at . Her peacetime complement was 158 officers and enlisted men.〔Friedman p. 465〕 The wartime complement increased to approximately 250 officers and enlisted men.〔Roscoe p. 20〕 ''Mahan'' had a tripod foremast and a pole mainmast. To improve the anti-aircraft field of fire, the tripod foremast was constructed without nautical rigging.〔Friedman p. 88〕 In silhouette, the ship was similar to the larger that immediately preceded her.〔Reilly p.28〕 She was fitted with the first emergency diesel generators, replacing the storage batteries of earlier destroyers. Gun crew shelters were built fore and aft for the superimposed weapons. A third quadruple set of torpedo tubes was added, with one mount on the centerline and two in the side positions. This required relocating one 5 inch/38 caliber gun to the aft deckhouse. ''Mahan'' incorporated a new generation of land-based steam propulsion machinery. With boiler pressures increasing to 600 PSI (pounds per square inch), and high-pressure turbines that had double reduction gears, which ran faster and more efficient than that of her predecessors.〔 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 Mahan (DD-364)」の詳細全文を読む スポンサード リンク
