KRIEGSMARINE U-BOATS & MTB SECTIONS

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. The latest variants of this design were capable of ranges of more than 23,000 miles, allowing them to rove far in search of convoys, while their heavy load of torpedoes allowed them to keep pace with a convoy, attacking night after night.
