The Tupolev I-12 (also known as the ANT-23) was a prototype Soviet fighter aircraft that never reached production. The I-12 was of unconventional design with twin booms made of water pipes containing recoilless rifles and two engines in a push-pull configuration. The aircraft first flew in 1931 but did not enter production due to disappointing performance and operational difficulties such as the inability for the pilot to escape the aircraft without hitting the propeller arc behind him. The second prototype from Tupolev (designated ANT-23bis) was never completed.[1] Specifications{{aircraft specifications|plane or copter?=plane |jet or prop?=prop |ref=Shavrov 1985[1] |crew=one |capacity= |payload main= |payload alt= |length main=9.5 m |length alt=31 ft 2 in |span main=15.6 m |span alt=51 ft 2 in |height main= |height alt= |area main=30 m² |area alt=322.9 ft² |airfoil= |empty weight main= |empty weight alt= |loaded weight main=2,400 kg |loaded weight alt=5,291 lb |max takeoff weight main= |max takeoff weight alt= |more general= |engine (prop)=Gnome-Rhône 9Ak |type of prop=radial engines |number of props=2 |power main=392 kW |power alt=525 hp |power original= |max speed main=300 km/h |max speed alt=162 kn, 186 mph |cruise speed main= |cruise speed alt= |stall speed main= |stall speed alt= |never exceed speed main= |never exceed speed alt= |range main= |range alt= |ceiling main= |ceiling alt= |climb rate main= |climb rate alt= |loading main=80 kg/m² |loading alt=16 lb/ft² |power/mass main=326 W/kg |power/mass alt=0.2 hp/lb |more performance= |armament=
