Project history: Works over new cruiser submarine were begun in 1934. Created as a result XIV series submarines had double-hull construction (the light hull was fulfilled completely welded) and strong armament. Mines were carried in mine-ballast tank and were laid "under herself". Besides two main diesels there was one more, ensuring cruising speed and battery recharging. On trials it was possible to reach set parameters of speed, but war experience has shown, that the endurance is much less than ordered. Maximal diving depth was 100m. From lacks there were marked weakness of an light hull and unsuccessful form of fore end because of what the boat strongly buried into a wave. With beginning of operations absence of non-bubble torpedo launching system has made itself felt (it was considered, that such large submarines after torpedo launch will be held on depth) that compelled commanders to shoot from maximal distances.
Modernizations: 1942, K-3, K-22: + type 129 sonar
Naval service: K-1 was lost between 5 and 28.9.1943; presumably, she was lost on mines laid by German cruiser Admiral Hipper off Novaya Zemlya. K-2 was lost between 26/8 and 7.9.1942; presumably on a mine. K-3 was lost between 14 and 23.3.1943 off Porsanger-fjord. K-22 was lost 7.2.1943 off Cape Harbaken, possibly on a mine. K-23 was sunk 12.5.1942 by German submarine chasers UJ1101, UJ1109 and UJ1110 and aircraft at Cape Nordkyn.
