MSFU crews signed ships articles as civilian crew members under the authority of the civilian ship's master. The ship's chief engineer became responsible for the catapult and the first mate acted as Catapult Duty Officer (CDO) responsible for firing the catapult when directed. The single Hurricane fighter was launched only when enemy aircraft were sighted and agreement was reached via hand and flag signals between the pilot, CDO and ship's master. The first CAM ship, Michael E, was sponsored by the Royal Navy while the RAF MSFUs were working up. After a trial launch off Belfast, Michael E sailed with convoy OB 327 on 28 May 1941. She was sunk by U-108 on 2 June. The first RAF trial CAM launch was from Empire Rainbow at Greenock on the River Clyde on 31 May 1941, the Hurricane landed at Abbotsinch. Six CAM ships joined convoys in June 1941. When a CAM ship arrived at its destination, the pilot usually launched and landed at a nearby airfield to get in as much flight time as possible before his return trip. Pilots were rotated out of CAM assignments after two round-trip voyages to avoid the deterioration of flying skills from the lack of flying time during the assignment. CAM sailings were initially limited to North American convoys with aircraft maintenance performed by the Royal Canadian Air Force at Dartmouth, Nova Scotia. CAM ships sailed on Gibraltar and Freetown convoys beginning in September, 1941, after an aircraft maintenance unit was established at the RAF base at North Front, Gibraltar. No CAM aircraft were provided during January and February 1942 after it proved impossible to maintain the catapult-mounted aircraft in flying order during the North Atlantic winter. CAM sailings resumed on 6 March 1942 on North Atlantic convoys and in April on the Arctic Russian convoys with a RAF aircraft maintenance unit in Archangelsk."@en .

There were also 2 dummy catapult ships, just added to worry the enemy, the CAPE CLEAR and CITY OF JOHANNESBURG. And finally 2 true Escort Carriers, HMS AUDACITY and PRETORIA CASTLE, the former ex-German HANNOVER, the latter only used for training. All the follow-on Escort Carriers, although on merchant ship-type hulls, were launched as carriers."@en . "CAM Ship"@en . . "CAM ship"@en . . . .
