Raubvogel (1923)

 The six Raubvogel (German:"Bird of prey") class torpedo boats were developed from earlier designs shortly after World War I and came into service in 1926 and 1927. They were the first to use electrical welding for hull construction to reduce displacement and they also introduced geared turbines. During the Second World War these ships were referred to as the Möwe class by the Royal Navy.

Despite the innovations, and unlike contemporary German destroyers, the Raubvogels were successful sea-boats, although limited to coastal waters, and most remained in service until 1944, by which time all had been lost. Well before this time, however, the deficiencies of their concentration on torpedoes became apparent: their anti-aircraft weaponry was wholly deficient, and had to be upgraded, and their guns were also minimal.

The immediately following six ships of Raubtier ("predator") class had been intended to mount 12.7 cm guns but, instead, received updated 10.5 cm weapons. Speed and range were improved. Otherwise, they displayed the same good and bad points as the Raubvogels and experienced similar operational conditions and upgrades.

They entered service in 1927 and 1928 and all but one had been lost before mid 1942.

During the St. Nazaire Raid ("Operation Chariot"), the destroyer HMS Campbeltown was altered by the Royal Navy to look like a Raubvogel class torpedo boat.

All twelve vessels were built at Reichsmarinewerft Wilhelmshaven
