Project history: Submarines of "combined"
type storing powerful torpedo armament at possibility to laid mines. In
construction experience of building of D class submarines
was used, and also decisions borrowed from raised British subarine L55.
Saddle-tank hull. Mines were carried in two horizontal watertight
tubes and laid astern.
Submarines of II series were built for Baltic and Black Seas. In 1934 for
Pacific Fleet there was begun building of XI series, in which construction
a number of changes was brought. These submarines
were laid down on European shipyards, then taken apart and transported by
railways for completion to the Far East. Maximal diving depth for II and XI series was 90 m; for subsequent 100m.
Modernizations: 1941-1943, all: - hydrophone; + Mars-16 hydrophone
1944, L-8, L-11, L-12; 1945, L-7, L-9: + type 129 sonar
