Ship History
The submarine "Revolutionary" was laid down on April 14, 1927 under the serial number 27/192 on the slipway of the factory number 198 in Nikolaev . When attempting to launch in March 1930, inadmissible rolls arose. The submarine project was recognized as wrecking, the chief designer and his assistants were sentenced to imprisonment for several years, but they were soon released on parole, and after the redesign of the diving-surfacing system , the boat was launched on April 6 , signed on December 30, 1930 acceptance certificate, the boat went into operation, received tail number 11. On January 5, 1931, the boat became part of the Black Sea naval forces.
During the war years, D-4 made 16 military campaigns, including 6 transport flights to besieged Sevastopol . Drowned the German transport “Boy Federsen” (the former Soviet “Kharkov”, 6,689 gb), the Bulgarian transport “Varna” (2,141 gb) and, probably, the German transport “Santa-Fe” (4,627 gb). Everything is near Cape Tarkhankut.
November 11, 1943 the boat went on a military campaign. The last time "D-4" was seen on December 1 from the submarine " Shch-209 ". The exact place of death and the causes of death are unknown, it is assumed that a minefield is undermined. Initially, it was believed that the boat was sunk by four German auxiliary anti-submarine ships, but in that episode the Sch-209 was attacked and received minor injuries.
