Submarines: A long-ranged submersible, the Type IX was the most successful U-boat of the war, with each vessel averaging over 100,000 tons of shipping sunk. One Type IX, U-107, made the most successful convoy mission of the war, with nearly 100,000 tons of shipping sunk out of Freetown in Africa.
MTBs: The R1-class of R-Boat (from the German Räumboot, meaning minesweeper) was intended to be used as a shallow water minesweeper but, as the war went on, it became a multi-role craft. Its duties expanded to include patrol, antisubmarine, convoy escort, minelaying, and rescue operations. Some classes of R-Boat, such as the R310, were fitted with torpedo tubes, though performance was very modest compared to craft specifically designed for the role.
