The Blohm & Voss BV 155 was a German high-altitude interceptor aircraft intended to be used by the Luftwaffe against raids by USAAF Boeing B-29 Superfortresses.〔 Work started on the design in 1942, but the design went through a protracted development period and was still under construction when World War II ended. ==Background== The performance estimates of the B-29 Superfortress first started reaching German command in early 1942. The B-29 would attack in a cruise at an altitude that no German plane could operate effectively. In the hope of countering attacks by this formidable bomber, the Luftwaffe would need new fighters and new destroyers as soon as possible. Work on a special high altitude fighter was started by Messerschmitt, but in 1943 the project was passed to Blohm & Voss. The result was the Bv155 prototype that made its first test flight in September 1944.〔Lepage 2009, p. 228.〕 The saga of the BV 155 began at Messerschmitt in the spring of 1942. At that time, it was known under the designation of Me 155, and was a company proposal for a carrier-based single-seat fighter. The Me 155 was intended to be based aboard the aircraft carrier , then under construction. In the interest of economy and simplicity, the Me 155 was to use as many Messerschmitt Bf 109 components as possible, being basically a navalized version of the earlier Messerschmitt fighter. The Me 155 was to be powered by a DB 605A-1 liquid-cooled engine of 1,475 PS (1,455 hp, 1,085 kW). The fuselage was more-or-less that of the standard Bf 109G, but with an entirely new wing. The undercarriage retracted inwards into wing wells, providing the wider track required for safe carrier landings. Standard naval equipment such as folding wings, catapult spools, and arrester gear were to be fitted. Proposed armament was an engine mounted 20 mm MG 151 cannon and two 20 mm MG 151 cannons and two 13 mm (.51 in) MG 131 machine guns in wings. It had an estimated maximum speed of 649 km/h (403 mph). Detail design of the Me 155 was complete by Sept 1942. However, the numerous delays in the ''Graf Zeppelin'' seemed to indicate that the completion of the carrier would be at least two years away. Messerschmitt was told to shelve the Me 155 project for the indefinite future. Work on the ''Graf Zeppelin'' carrier was eventually abandoned. In order that all of that work on the Me 155 project not go entirely to waste, Messerschmitt adapted its design in November 1942 to match a ''Luftwaffe'' requirement for a fast single seat bomber. A single 1,000 kg (2,210 lb) SC 1000 bomb was to be carried. All of the carrier equipment and most of the armament was removed from the aircraft. Additional fuel tanks were provided and an elongated, non-retractable tailwheel was added to provide ground clearance for the large bomb. The proposal was designated Me 155A. 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「Blohm & Voss BV 155」の詳細全文を読む スポンサード リンク
