The original "H" Class design of 1919 was for a twin engined airship of approximately 80,000 cubic feet volume. Commander Lewis Maxfield (who was to have commanded the ZR-2, better known as the ''R38'', and died in its crash) suggested that a small airship which could be used either as a tethered kite balloon, or be towed by a ship until releasing its cable, would be able to scout on its own.〔Shock, James R., U.S. Navy Airships 1915-1962, 2001, Atlantis Productions, Edgewater Florida, ISBN 0-9639743-8-6, page 35〕 The concept was an airship similar to the later Army Motorized Kite Balloons. ==Operational history== After test flights at Wingfoot Lake, ''H-1'' was shipped to Rockaway in May 1921. During the summer of 1921, ''H-1'' completed six flights and, on its seventh, a hard landing pitched the crew out of the control car. ''H-1'' free ballooned as far as Scardale, New York where a farmer was able to grab the rip cord and tie the blimp down. During the night it was deflated. The deflated ''H-1'' was shipped back to Rockaway in time to be destroyed in the hangar fire of August 31, 1921.〔Shock, James R., U.S. Navy Airships 1915-1962, 2001, Atlantis Productions, Edgewater Florida, ISBN 0-9639743-8-6, page 35〕 A second H-type was acquired on a Navy contract but supplied directly to the U.S. Army which operated it as the OB-1. OB-1 varied in several ways from the H-1.〔Shock, James R., U.S. Navy Airships 1915-1962, 2001, Atlantis Productions, Edgewater Florida, ISBN 0-9639743-8-6, page 36〕 The shift from hydrogen to helium lift gas in 1923 seriously degraded the OB-1's performance. The OB-1 was damaged on 6 October 1923 and never re-inflated as the forthcoming TA type airship would meet the training role. OB-1 was declared surplus at the end of 1923.〔Shock, James R., U.S. Army Airships, 1908-1942, 2002, Atlantis Productions, Edgewater Florida, ISBN 0-9639743-9-4, page 60〕 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「H-class blimp」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
