History of design and construction

The main designer of the first series of the Dekabrist-class submarines was Boris Mikhailovich Malinin (1889-1949).

He was one of the few engineers who personally participated in the construction of submarines before the Revolution of 1917. Based on this experience and scanty theoretical data, Malinin, with a group of designers, proceeded to development of materials for construction of the first Soviet submarine.

On March 5, 1927, at the Baltic Shipyard in Leningrad, the first three submarines: Dekabrist, Narodovolets and Krasnogvardeyets were solemnly laid down.

The first rivet in the bilge of the forerunner was nailed by S.M Kirov. A silver plate was fastened to the submarine's buoyancy control tank, where B.M. Malinin was named as the submarine construction manager. On November 3, 1928 Dekabrist was launched; on May 19, 1929 submarine Narodovolets was launched, and on October 12, 1931 it became part of the Baltic Sea Naval Fleet.
