The Irish AC became an AW139 operator in 2006, and has six units on strength (serialled 274 through 279). Of those, "274" shown here is the only AB139 (the others are AW139's), and served as "Air Corps 112" when photographed. "AC112" is a joint air ambulance helicopter service operated by the Irish Air Corps and the Irish National Ambulance Service (NAS) since 2012. Previously called "MEDEVAC 112", the service was redesignated to "AIR CORPS 112" in 2016. The IAC provides the flight crew, while the NAS is responsible to staff the medical personnel.
