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 five to seven persons (including pilot).
The A-7 was an all-wooden high-wing monoplane, with a retractable undercarriage.
It was evaluated in late 1941 and ordered for production, under the designation A-7 (Antonov, seven persons). Approximately 400 were built. In late 1942 – early 1943, an unusual variant was tested – a tanker glider, fitted with a 1000-litre fuel tank, hauled by a DB-3 bomber which was refuelled during flight in order to increase range. It was not produced.
