The 4x4 vehicle was airlifted three miles (4.8km) by a RAF Chinook helicopter on to Caldey Island, reports the BBC.
Caldey Island has only 40 inhabitants, including 18 monks who live at a monastery.
The fire appliance will be manned by volunteers from the small fishing and farming community.
Wing Commander Phil Greville, RAF regional liaison officer in Wales, told South Wales Evening Post: "Air-lifting this type of vehicle underneath a Chinook has not been done before.
"The fire service needed to get a new fire appliance out to the island and we wanted to get this type of fire-vehicle approved for air-lift by Chinook.
"The rural response pump vehicle is in widespread use throughout the UK and in the future, we will be able to fly it to where it is needed when responding to major floods and other emergency situations."
