Tupolev ANT-22

ANT-22 and MK-1

Manufacturer: Tupolev
First flight: 1934

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 a follow-up to the ANT-8. Its enormous weight severely crippled its performance; it never got beyond the experimental stage.
