GM Designer. Beriev after the transfer of the plant in the CDB. Menzhinsky engaged in the development of its project. With the participation of the Air Force Institute, he opted for the sea near scout. Originally, he had planned to do an all-metal aircraft, However, representatives of the Research Institute of Naval Aviation insisted on a wooden structure. Considering this request, Beriev decided to make a wooden car, as simple as, designed for mass production. During the design was a large volume of research on various models in wind tunnels and experimental TsAGI pool.

After finishing the project design, Beriev submitted it to the technical council of CDB, We approved the project and decided to build a prototype, were designated as CDB-25. By the fall 1931 g. aircraft was built, but the engine M-27 which was supposed to be installed on aircraft, not produced in series. Plant manager ordered to immediately stop all work, and the fate of the plane hung in the balance. I had to urgently look for the new engine and the decision of GM. Berieva install a license engine M-17, true, with less power. spring 1932 g. disassembled the plane by rail delivered in Sevastopol on gidrobazu plant number 45. The first flight was scheduled for 30 April, but he did not take place. Plane on erratic truck was launched, but the truck did not want to move away from the plane of the bottom even with the boat jerks. When the plane out of the water, It revealed, kuzbaslakom that covered the bottom of the boat stuck to erratic box truck, who forgot to grease grease. Only 3 May the second attempt managed to lift the plane in the air. Factory tests conducted by test pilot B.L. Bukhgolits. Tests passed quickly, there were even no different dovodok. The aircraft showed good flight data, It was stable in the air and on water, easy to manage.
MBR-2 was recommended in a series and adoption. At a meeting of representatives of the Air Force and the aviation industry against unexpected start-up in the series spoke AN. Tupolev. Instead, "this piece of wood," he offered his all-metal flying boat MBR-2. At the suggestion of the Chief of TsAGI NM. Kharlamov GM. Beriev instructed to develop a passenger version of the MBR-2, expand which will be much easier to manufacture. But then 1933 g. Chief CDB becomes SV. Ilyushin, and GM. Beriev was appointed head of the brigade number 5 (sea planes). The issue of the serial production of the MBR-2 was resolved, determined and the plant - № 39 Taganrog. After eliminating the drawbacks factory produced two series for military trials, and then began mass production MBR-2, which was terminated in the second half 1940 g. Originally built car with an engine M-17, and then M-34 (all were released 1365 cars of all modifications).
A modification of the MP-1 for a long time served as places for civil aviation, where there were no airfields. crew PD. Asipenka this aircraft set several world records in the class seaplane. The parade of the MBR-2 began arriving in 1934 g. In 1937- 1938 gg. flying boats GM. Beriev seaplanes were the main naval aviation. MBR-2 was involved in three wars: in August 1938 g. in Lake Khasan, at 1940 g. during the Finnish War and the Great Patriotic War. From the first days of the planes involved in combat operation and used around the clock, and mainly in the land theaters. Large losses of aircraft soon forced to switch to night bombing assault against. After the war ended combat service grown old MBR-2. A little more than they were exploited in the CAF.
