The Antonov A-7 was a Soviet light troop military glider of World War II. ==Development== Shortly after the German attack in 1941, Soviet headquarters realized a need for transport gliders and ordered the development of several designs. Oleg Antonov offered a light glider, of which preliminary sketches had been drawn in 1939. It was first named RF-8 (''Rot Front-8'') and was essentially an enlarged variant of a sports glider, the RF-7. Following trials, its capacity was increased from 5 to 7 persons (including pilot). The A-7 was an all-wooden high-winged monoplane, with a retractable undercarriage.〔 It was evaluated in late 1941 and ordered for production, under the designation A-7 (Antonov, 7 persons). Approximately 400 were built. In late 1942 – early 1943, an unusual variant was tested – a tanker glider, fitted with 1000 litre fuel tank, hauled by DB-3 bomber, which was refuelled during flight in order to increase range. It was not produced. 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「Antonov A-7」の詳細全文を読む スポンサード リンク
