U-Jagdboot [Submarine hunter] "Thetis" class (420)

The German Navy presented the early 1960s five torpedo fishing boats in service. This should cooperate especially with destroyers and were therefore designed seaworthy and exceptionally large. Over time, the application range of the boats changed. The units have been converted only to fleet service boats and 1974 eventually turned into U -Jagdbooten.

Originally, these vehicles were provided as Torpedo fishing boats for the fleet squadron service. The maritime units should capture their scoring exercise torpedoes in cooperation with the destroyers of HAMBURG class and other units, stored on board and wait. As the boats proved because of their relatively high lift, particularly in rough seas, as unfit, they were converted to U -Jagdbooten.

After laying in the Baltic Sea area, the boats were mostly shut for the Marine schools located there. Early 90s the units were decommissioned and handed over to the Greek Navy. There the vehicles were partially renamed and integrated into the fleet.
