The Kriegsmarine's
torpedo boats of World War Two were intended to be used in the same way as had
been done during the first World War, To single out a larger surface vessels and
attack it with torpedo's but it soon became obvious that these kind of attacks
were no longer possible. The new generation of torpedo boats built after the first
Word War were more like small destroyers, But those built in the 1930 were lightly
armed and were designed for mainly torpedo attacks. These vessels turned out to
be of no practical use so they were used for escort duty, mine laying, surface
patrols or U-boat training.
