Ship project history: Ordered 30/5/1930, development of O12 project with increased dimensions and additional twin turnable TT in a superstructure fwd from a conning tower. Also one stern TT was added. Double-hulled. At building welding was widely applied to weight reduction. Besides two usual periscopes, submarines were equipped with periscopic antenna for possibility to use the radio in submerged position. On trials they reached up to 19kts surfaced. Both 40mm MGs took places in disappearing installations.
Modernizations: 1942-1943, K XIV, XV: - 2 x 1 - 40/40, 1 x 2 - 533 TT; + 1 x 1 - 20/70 Oerlikon, type 291W radar
