Project history: First submarines built in Germany after a cancellation of Versailles limitations. As prototype Finnish submarine Vesikko, designed in Germany on the basis of coastal submarines of types UB-II and UF of the First World War period was been taken. II series submarines differed from a prototype by increased machinery power and fuel stowage and improved manoeuvrability. These submarines received in Kriegsmarine nickname "canoe".
Single-hulled, with internal ballast tanks. Operational diving depth was 80m, maximal 120m; diving time was 25-35sec. Welding, widely used at building, allowed to lower hull weight. Differences between types were brought together basically to increasing of hull dimensions and fuel stowage. First two series originally did not receive artillery, guns were installed already during service; since type IIC 20mm MG has been included in the project. Instead of torpedoes submarines could carry 12 TMA or 18 TMB mines.
To beginning of war majority of boats of II series served in training role, but then they began to be got to take part in battle operations, including minelaying.
Modernizations: 1942-1943, many survived: + FuMO 30 radar, FuMB 1 Metox ECM suite
1943-1944, most survived: - FuMB 1 Metox ECM suite; + FuMB 3 Bali, FuMB 6 Palau ECM suites
1944-1945, some survived: - FuMO 30 radar; + FuMO 61 radar
Naval service: U138 was sunk 18.6.1941 by British destroyers Faulknor, Fearless, Foresight, Forester and Foxhound W off Cadiz. U144 was torpedoed 10.8.1941 by Soviet submarine Shch-307 W off Dago. U147 was sunk 2.6.1941 by British destroyer Wanderer and corvette Periwinkle NW off Ireland.
Following submarines were scuttled by crews: U137, U139, U140, U141, U142, U146, U148, U151 and U152 5.5.1945 at Wilhelmshaven.
U143, U145, U149 and U150 surrendered and were scuttled by Allies during operation "Deadlight".
