A development of the Hispano-Suiza Ybrs engine licence-built in USSR since 1935 under the designation M-100. That licence was purchased in order to obtain a powerful inline engine for fighter aircraft. Vladimir Yakovlevich Klimov was responsible for the licence purchase, introduction of the engine to production and further modifications.
In comparison with the M-100, the M-103 had increased compresion ratio and RPM of the supercharger. The cruise power increased from 780 to 850 hp. In 1938 the M-103A version, with the take-off power of 1,000 hp was introduced. The M-103 was used in the SB-2 bomber aircraft. As a result of subsequent changes and improvements of the license, the new Klimov’s engine, M-105, known later as VK-105, appeared. It was built in large numbers during World War II.
