The Chetverikov MDR-6 was a 1930s Soviet Union reconnaissance flying-boat aircraft, and the only successful aircraft designed by the design bureau led by Igor Chyetverikov.

First flying in July 1937, the MDR-6 was a two-engined high-wing monoplane of all-metal stressed skin construction. The prototype was powered by two M-25 radial engines. A production run of 20 units powered by M-63 engines were produced in 1940 and 1941. All the aircraft were withdrawn from service in 1942 due to structural problems.[1]

Several progressively advanced prototypes were built from 1939 to 1945, but no further production ensued.
