The Air Corps currently operates two Casa CN 235 Maritime Patrol Aircraft. These aircraft entered service in 1994 and operate seven days a week usually in the off shore maritime patrol arena.

Working in close conjunction with the Naval Service, the two Casa CN 235 Maritime Patrol Aircraft of 101 Squadron provide an aerial platform for patrolling the Irish Economic Zone, an area of approximately 132,000 square miles or 16% of the total EU sea fisheries. This in itself represents an area almost five times the land area of Ireland and encompasses perhaps one of the most productive fisheries in the world.
