Offshore Patrol Vessel

The Naval Service operates three offshore patrol vessels. All these vessels were built in Verlome Dockyard in Cork and were commissioned into service during the late 1970s and early 1980s.  These vessels patrol the Irish EEZ. During their service these vessels have completed numerous re-supply missions to Irish troops serving overseas with the United Nations.
