The Antonov A-9 was a single-seat sailplane designed and built in the USSR. In 1952, on the basis of the A-9, A Manotskov developed an original experimental glider with flapping spring-mounted wing - the Kazhuk. It was first flown in 1953 and on 9 June 1954, it participated in the air show at Tushino airfield. Eventually only 27 were built. In March 2009, this Kazhuk was first reported with the museum at Monino.
