Hermann Stuckmann began his naval career shortly after the start of the war, in September 1939. He got his basic training on the school ship Schleswig Holstein and took part in the occupation of Denmark in April 1940. In July 1941 he was attached to the U-boat force and served as watch officer for more than a year on U-571 under the command of Kptlt. Helmut Möhlmann.

He left U-571 in May 1943 and three months later commissioned the type VIIC boat U-316, which he commanded until May 1944 as a school boat in the Baltic Sea. In May 1944 he took command of the combat boat U-621 and fought in summer 1944 against the Allied landing ships in the English Channel. During these patrols he sank two landing ships.

Hermann Stuckmann died when U-621 was sunk with all hands on 18 August, 1944 in the Bay of Biscay near La Rochelle by depth charges from Canadian destroyers (Niestlé, 1998).
