Type VII U-boats were the most common type of German World War II U-boat. 703 boats were built by the end of the war. The lone surviving example, U-995, is on display at the Laboe Naval Memorial located in Laboe, Schleswig-Holstein, Germany.

At the start of the Second World War the Type VII class was together with the British U, S and T class and Dutch O 21 class one of the most advanced submarine classes in service.^[7]
