The I-218 was an attack aircraft designed and built in the USSR from 1947.

Development

Alekseyev designed the I-218 as a heavily armed, and armoured, attack aircraft for use in close support and anti-tank missions. The twin boom aircraft had a central nacelle housing the pilot and gunners cockpits as well as the engine and forward firing armament. All armoured and highly stressed parts were manufactured from 30KhGSNA nickel-steel. Flight testing may have commenced in 1948, but there is no direct evidence of this. Shortly after completion Alekseyev's OKB was closed and Alekseyev was sent to TsAGI (Tsentrahl'nyy Aerodinamicheskiy i Ghidrodinamicheskiy Institoot- central aerodynamics and hydrodynamics institute) before being given the task of supervising Dr. Brunolf Baade and his German team at OKB-1. The designation I-218 is in doubt and the aircraft may have been called, simply 218.
