Project history
In 1943 Germany transferred to Italy 9 submarines of VIIC and VIIC/41 series in exchange for Italian oceangoing submarines which were supposed to be converted to transports for routes to the Far East. In September, 1943 all 9 submarines (S1-9) were accepted by Italian crews in Germany and after armistice signing between Italy and Allies they were commissioned by Kriegsmarine. Two additional boats, S10 and S11, were never actually transferred.
Modernizations
None.
Naval service
All were re-commissioned by Germany 9.9.1943.
