ANT-29, DIP by A.N.Tupolev

14k b/w drawing of ANT-29 (by I.G.Sultanov) from History of aircraft construction in the USSR V.B.Shavrov Vol.2 p.11

evelopment of the MI-3D/ANT-21bis type, fighter with absolutely unique armament. It was armed with a recoilless 102mm cannon DRP designed by L.V.Kurchewski. To eliminate the recoil, a weight was ejected by a nozzle fitted below the tail.
Construction started on June 1, 1933. The aircraft inherited all problems of its predecessor, and failed to pass factory tests. State acceptance trials, scheduled for first half 1936 never took place.
The gun was quite non-practical. Plus it completely lost its value with introduction of RS-82 rockets, which could be accommodate on any fighter without major modifications of the aircraft.
No mass production.
