Role Reconnaissance flying boat

The Tupolev ANT-22 (also known as the MK-1) was a large flying boat built in the Soviet Union in 1934. A huge aircraft consisting of two hulls and powered by six engines in three nacelles in a push-pull configuration, it was based on the ANT-11, which was never built.[1] Its enormous weight severely crippled its performance, and it never proceeded beyond the experimental stage.
