Description
Notes: The VII.A had limited fuel capacity, so 25 Type VII.B boats were built between 1936 and 1940 with an additional 33 tonnes of fuel in external saddle tanks which added another 2,500 nautical miles (4,600 km; 2,900 mi) of range at 10 knots (19 km/h; 12 mph) surfaced. More powerful engines made them slightly faster than the VII.A. They had two rudders for greater agility. The torpedo armament was improved by moving the aft tube to the inside of the boat. Now an additional aft torpedo could be carried below the deck plating of the aft torpedo room and two watertight compartments under the upper deck could hold two additional torpedoes giving it a total of 14 torpedoes.Class Overview
