The Elbing class torpedo boats (or Flottentorpedoboot 1939) were a class of 15 small warships that served in the German Kriegsmarine during World War II. Although classed as Flottentorpedoboot ("fleet torpedo boat") by the Germans, in most respects—displacement, weaponry, usage—they were comparable to contemporary medium-size destroyers. The most notable difference was in the armament of the Elbings being fewer in number and of a slightly smaller caliber — compared to the of contemporary British destroyers such as the "L" and "M"-classes.
