[edit] Design
The MBR-2 was designed by Georgy Mikhailovich Beriev and first flew in 1931, powered by an imported 500 hp BMW VI.Z engine. Production models, which arrived in 1934, used a licence-built version of this engine, the Mikulin M-17 of 680 hp, and could be fitted with a fixed wheel or ski undercarriage.
Beriev also designed a commercial airliner derivation, the MP-1, which entered airline service in 1934 and a freighter version, which followed in 1936.
In 1935, an improved version was developed, the MBR-2bis, powered by the Mikulin AM-34N engine, and fitted with an enclosed cockpit, dorsal gun-turret and enlarged vertical tail. In this configuration, the machine remained in production until 1941. As with the MBR-2, the bis spawned a commercial derivative and the MP-1bis entered service in 1937.
