Leninets-class submarine

The Leninets or L class were the second class of submarines to be built for the Soviet Navy. Twenty-five were built in four groups between 1931 and 1941. They were minelaying submarines and were based on the British L-class submarine, HMS L55, which was sunk during the British intervention in the Russian Civil War. Some experience from the previous Dekabrist-class submarines was also utilised. The boats were of the saddle tank type and mines were carried in two stern galleries as pioneered on the pre-war Russian submarine Krab (1912). These boats were considered successful by the Soviets. Groups 3 and 4 had more powerful engines and a higher top speed.
