German submarine U-40 was a Type IXA[3] U-boat of Nazi Germany's Kriegsmarine that operated during World War II.[1]

U-40 was built in Bremen by DeSchiMAG AG Weser as yard number 945. She was launched in November 1938 and commissioned in February 1939.[1]

U-40 conducted two war patrols during her career. Both of which were part of the 6th U-boat Flotilla. During her short time in the war, she sank no ships.

U-40 was sunk on 13 October 1939 by a mine in the English Channel.[1]
