Catapult Armed Auxillary Ship

CAM ship with Hurricane on catapult


HMS Patia was a Catapult Armed ship or Fighter Catapult ship. It was a representative of the Pegasus Class consisting of Ariguani, Maplin, Patia, Pegasus and Springbank with FAA aircraft. Each of these merchantmen were equipped with one Fleet Air Arm or RAF fighter and a temporary catapult. When threatened by enemy planes, the fighter took off. When it was done, it ditched, and the pilot was (theoretically) picked up by the merchant ship's convoy.

As an interim measure until more escort carriers could be made, selected British or Dominion merchant ships were fitted with an obsolescent Hawker Hurricane fighter to protect the ship convoys against air attack or reconnaisance overflights. The pilot was the only Fleet Air Arm or RAF crew member on board, and had little to do unless the plane was needed. If an emergency arose, the aircraft would be catapulted off to do combate, then the pilot had to ditch and be fished out of the water. Though the aircraft could only be used once, they even had their landing gear deleted to save weight, they could save a convoy from air attack.

The first catapult launch from a moving ship was by Lt.Cmdr. H.H. Mustin in a Curtiss AB-3 flying boat on 16 July, 1916, launched from the USS North Carolina (ACR-12). In the second world War the first FAA pilot shot from a catapult ship was by Lt Birrell in 1941.
