The Type XI U-boat was planned as an artillery boat; its main armament would have been four 128-mm guns, in two twin gun turrets. It would have also carried an Arado Ar 231 collapsible floatplane. Four boats (U-112, U-113, U-114, and U-115) were laid down in 1939, but cancelled at the outbreak of World War II. Had the Type XI U-boat been constructed, it would have had a completely new hull design and a submerged displacement of 4,650 tons – she would have been by far the largest of the U-boats and the second-largest diesel submarine after the Japanese I-400-class submarine. Its purpose was to engage ships (including escorts) in artillery duels at relatively long range, then dive away if they came within a certain threshold distance. Many anti-submarine escorts of WW2 including the Flower corvettes would have been too small and too poorly equipped with forward guns to cope with this approach.
