MBR-2 series with M-17 engine, G.M.Beriev
Series production of the MBR-2 started on Taganrog State Aircraft Factory N°31 (Named after G.Dimitrov) in 1934. It differed from the TsKB-25 prototype only by engine (BMW-VI replaced by domestic clone M-17).
About 1/3 of all 1365 built MBR-2 w ere of this modification.
MBR-2 is a mixed construction (mostly wooden) flying boat with shoulder wing and pusher engine, installed on high struts above the wing. Four-blade variable-pitch (???) propeller is a 'composite' of two standard 2-blade propellers (diameter 3.0m). Balance floats are located close to 1/2 of the wing span. Tailplane is installed on 1/2 of the fin. Aircraft is provided with dual controls (starboard column is removable). For winter operation MBR-2 detachable skis may be installed. Some aircraft were actually built in amphibious configuration. Protected fuel tanks are located in center wing section (2x330l). Two removable tanks (215l each) may be installed in the hull.
Armament included two TUR-6 open installations for 7.62mm DA, replaced later by TUR-8 with ShKAS machineguns. Normal bomb load - 400kg. Installation of unguided RS-82 was studied, but never became a production option.
Photoequipment is installed in the nose. Radio receiver and transmitter (in pilot's cockpit) is a standard option. All three (nose, pilot's and rear) cockpits are connected by ship-style voice pipes.

MBR-2 was very easy to built and maintain. It proved also quite a seaworthy, capable to land and takeoff from waves up to 0.7m. Reliable sturdy aircraft played large role in Great Patriotic War, being a major ASW aircraft of Soviet Naval aviation. Serving at all theaters, it performed reconnaissance, bombing, escort and even air-to-air combat against Nazi bombers (while protecting convoys).
Retired military MBR-2 with M-17 were used in civil service as MP-1T cargo planes.
