Large Patrol Vessel

The Naval Service operates two Large Patrol Vessels. These vessels were built in Appledore Shipyards in the U.K. These vessels were commissioned into service in the late 1990s and early 2000s. These vessels patrol the Irish EEZ as well as waters further out into the Atlantic Ocean. In their short service these vessels have completed numerous foreign deployments including L.É. Niamh’s historic far east deployment in 2001.
