Fighter catapult ship

Fighter catapult ships (FCS) also known as Catapult Armed Ships were an attempt by the Royal Navy to provide air cover at sea. Five ships were acquired and commissioned as Naval vessels early in the Second World War, and these were used to accompany convoys. The concept was extended to merchant ships which were also equipped with rocket-assisted launch systems and known as Catapult Aircraft Merchantmen (CAM ships). Both classes could launch a disposable fighter (usually a Hawker Hurricane) to fight off a threat, with the pilot expected to be rescued after either ditching the aircraft or bailing out close to the launching ship.

The ships

There were five fighter catapult ships, collectively known as the Pegasus class. Two, Patia and Springbank, were lost during the war. They were each equipped with a Fulmar or "Hurricat" (an adapted Hurriane Mk.1A).

She was a training ship from 1941 to 1944, in reserve from September 1944 and subsequently an accommodation ship. Maplin's war service was on Atlantic convoys and her "Hurricat" was the first to destroy a Luftwaffe aircraft, a Focke-Wulf Fw 200 in August 1941. The pilot was Robert Everett of 804 NAS.[2][3]
