Close range maritime reconnaissater, similar to successful MBR-2 aircraft. The general layout was unchanged, while size and weight were decreased approximately by 50%. Radial engine with tractor propeller was installed.

Construction - mixed. Wooden hull covered with fabric. Wing spars - wielded steel tubes, skin - fabric. Retractable main landing gear and tail skid allowed MBR-5 to operate from both shore and sea. Two machineguns were installed in covered turrets, bombs under the wing also covered with fairings.

Aircraft was ready in August 1935. Performance was very good, but factory trials were plaqued with series of minor troubles (fire, failures). During flight to Sevastopol for state acceptance, the only aircraft was crash-landed. MBR-5 was restored in September 1936, but project was cancelled.
