U-Boat Type VIIC, Kriegsmarine `Workhorse` of WW-II
Type VIIC was a slightly modified version of the successful Type VIIB, they had basically the same engine layout and power, but were slightly larger, and heavier which made them not quite as fast as the VIIB.

The VIIC was the `Workhorse` of the German U-boat force in World War II from 1941 onwards-some 568!! boats of this type were built throughout the war. The first VIIC boat being commissioned was the U-69 in 1940. The VIIC was an effective fighting machine and was seen in almost all theaters of war although their range was not as long as that of the Type IX.

The larger mine-laying Type VIID was a direct variant of the VIIC.
