Escort ship Anti Submarine Corvette

ESCORT SHIPS (Anti-submarine corvette) 1961

TRITON One of a class of five small corvettes constructed for the Federal German Navy in the early 1960s and later used for coastal antisubmarine patrols.
Extended Description
THE THETIS CLASS
Originally, these small ships were to have been used to recover practice torpedoes fired during training and on exercise, but it soon became clear that they could not actually fulfil that role, and they were employed as general-purpose service craft instead, particularly in the weapons school's training units. Thetis (P 6114, but also A 1433 and P 6055) was the fourth unit, constructed (like all the rest) by Rolandwerft at Bremen. Laid down in 1960, she was launched on 5 August 1961 and entered service on 10 November 1962. She was decommissioned in September 1992 and sold to Greece, where she became the Elevtheria (P 64) from 30 April 1993.

RE-EQUIPPED FOR A NEW ROLE
During the 1970s, the five ships were taken in hand for modification to the role of coastal submarine hunters, fitted with ELAC 1 BV sonar and a four-tube launcher for Bofors 375mm(l Ain) anti-submarine rockets on the foredeck. They retained their twin 40mm Bofors AA guns aft, but their twin torpedo tubes were exchanged for four capable of deploying wire-guided missiles. They lost their now-redundant crane and associated torpedo recovery gear. On transfer to Greece they were re-equipped with tubes to launch lightweight 12.75in (324mm) torpedoes.
