Boris Mikhailovich Malinin (1889-1949) was a Soviet shipbuilding scientist who designed the Shchuka-class submarines produced in 1930-1945.
Shchuka-class submarines were remarkable for their relatively cheap production, simple maintenance, manoeuvrability and robustness. These submarines were extensively used in combat in the Great Patriotic War and sank many enemy ships. Some submarines of this class became guard submarines for their battle merits.
