Osprey 55 class gunboat

Osprey 55 class gunboat HS Navmachos (Κ/Φ Ναυμάχος) at Faliron Bay.

The gunboat class Osprey 55 is a Danish-designed class of naval ship currently in service in the Hellenic Navy. Two ships were ordered in March 1988. The first one was laid down on 8 May 1989 and launched on 19 December 1989. The second ship was laid down on 9 November 1989 and launched on 16 May 1990. Armament is of modular design and therefore can be changed. 76-mm guns replaced the Bofors 40-mm in 1995, after being taken from decommissioned Gearing-class destroyers. Options on more of the class were shelved in favour of the Gunboats Class HSY-55.
