Based on the successful design of the Flottentorpedoboot 1939, the Flottentorpedoboot 1941 should improve the few flaws of their predecessors. Therefore the engines were more powerful and additional anti aircraft artillery was added.
15 of those boats were ordered in 1942-1944, but none of them was completed. At the end of the war, the few ships already launched were in different stages of construction, one of them, the T37
was very close to completion. Those ships which could be moved to the west were towed away from Elbing, but their construction was not continued.
