Thetis-class gunboat

The Thetis-class gunboats, was a class of five naval ships of the Hellenic Navy, originally developed for the German Navy as Class 420 and first commissioned in 1961. Similar in size to corvettes, all five vessels were built by Rolandwerft, Bremen. In the German Navy there were designated as submarine hunters (U-Jagdboote).

The main armament of Thetis class ships consisted of 20-mm and 40-mm guns, Mk 46 Mod5 torpedoes and mines and A/S mortars. The ships were also equipped with sonar. Later the A/S mortars were replaced by a second 40-mm gun and the single torpedo tubes by triple mountings. Upgrades started in 2000 may have included enclosed 40-mm gun mountings and Rheinmetall 20-mm guns to replace the MGs. The last two ships of the class were decommissioned on 22 April 2010.
