Gunboats Class HSY-55

From Wikipedia, the free encyclopedia

The first pair was ordered in 20 February 1990. This is a design by the Hellenic Navy which uses the modular concept so that weapons and sensors can be changed as required. Appearance is similar to Gunboats Class Osprey 55. Pyrpolitis (P57) was launched 16 September 1992 and Polemistis (P61) 21 June 1993. Completion was delayed by the shipyard's financial problems. Alternative guns and Harpoon SSM can be fitted. 25 fully equipped troops can be carried. Engines are resiliently mounted.
