Offshore Patrol Vessels
Sirio Class
The main mission of Offshore Patrol Vessels is to safeguard national interests through patrolling activities and carry out anti-pollution and rescue services. The aft area is often fitted with a flight deck for the take-off and landing operations of one mediumsized helicopter. Typical features of such vessels are the extensive range as well as sea-keeping and manoeuvrability performances, which make them highly flexible from the operational point of view.
