What does the Irish Naval Service do?

The Naval Service is the State’s principal seagoing agency maintaining a constant presence 24 hours a day, 365 days a year throughout Ireland’s enormous and rich maritime jurisdiction, upholding Ireland’s sovereign rights. The Naval Service is tasked with a variety of roles including defending territorial seas, deterring intrusive or aggressive acts, conducting maritime surveillance, maintaining an armed naval presence, ensuring right of passage, protecting marine assets, countering port blockades; people or arms smuggling, illegal drugs interdiction, and providing the primary diving team in the State.

The Service supports Army operations in the littoral and by sea lift, has undertaken supply and reconnaissance missions to overseas peace support operations and participates in foreign visits all over the world in support of Irish Trade and Diplomacy.  The eight ships of the Naval Service are flexible and adaptable State assets. Although relatively small when compared to their international counterparts and the environment within which they operate, their patrol outputs have outperformed international norms.
