The Cassiopea class is a heavy series of four patrol boats of the Italian Navy. They were built in the late 1980s on civilian standards. They are designed for patrol in safe areas.

Development and design

In the early 1980s the Italian navy developed two classes of corvettes to replace older vessels. The Minerva class were fully combatant ships to serve as coastal escorts, and equipped with modern sensors and armament, while the Cassiopea class were simpler offshore patrol vessels intended to replace the old Albatros-class corvettes used for fisheries patrol.[1][3]

Vega

Construction of four ships (out of an originally planned eight) was authorised in December 1982, with funding coming from the Ministry of Merchant Marine, while orders were placed in December 1986, with construction at Fincantieri shipyard, Muggiano to merchant ship standards, starting the next year, and the first ship entering service in 1989. A further two ships were cancelled unbuilt in 1991.[1][4]

The ships' main gun armament is a single 76mm/L62 Allargato gun, with both gun and fire control systems coming from scrapped Bergamini-class frigates. The ships are fitted with a flight deck and fixed hangar to accommodate a helicopter type Agusta-Bell AB-212 ASW of the Italian navy. The ship also carries equipment for dealing with pollution.[1] During years 2012/2014 all units were fitted with Selex ES Janus-N IR optronic system. Since 2014 the vessels (first was Libra) were fitted with new navigation biband (X/Ka) Gemini-DB radar of GEM Elettronica.
