The 1934 class Zerstorer was the most numerous type in the Kriegsmarine at the outbreak of WWII. German Destriyers or Zerstorer and Large Torpedo Boats or gross Torpedoboote were basically the same and had very little distinction between them. The term Destroyer did not come into effect witht he German navy7 until the B.97 class which was built in 1914/1915. Unto this time the Torpedo Boats and Destroyers were not named except with a consecutive number and a letter denoting the Naval yard it was built at. The three main builders up to 1912 was Germaniawerft, (prefaced with B) A.G Vulcan (prefaced with V ) and Schichau (prefaced with S) another three yards started building after 1912 and they were Blohn and Voss (prefaced with B) Howaldtswerke (prefaced with H ) and Wilhelmshaven Imperial
While the hulls were relatively old by the time they saw action, these light Destroyers were very effective as convoy escort and attack, providing AA cover for fleet operations and utilizing the ability to mount torpedo attacks against other shipping. Destroyers can carry troops into an amphibious assault or invasion style operations also. Until the advent of Motor Torpedo Boats (MTB’s) the Light Destroyer class were the fastest boats available for battle in the coastal regions and open oceans.
