Flag Officer, Carriers and Amphibious Ships (FOCAS) was a senior Royal Navy post that existed from 1970 to 1979. However, its antecedents date to 1931.
A Flag Officer with specific responsibilities for command of aircraft carriers within the Royal Navy was first established in September 1931 with the appointment of Rear-Admiral Reginald Henderson as Rear-Admiral, Aircraft Carriers.[1] He was succeeded by Rear-Admiral the Hon. Sir Alexander R. M. Ramsay later Vice-Admiral, Aircraft Carriers. The post was held by successive flag officers under the titles listed below. In June 1968 the post Rear-Admiral, Carriers was renamed to Flag Officer, Carriers and Amphibious Ships (FOCAS). The post was renamed Flag Officer, Third Flotilla in December 1979.[2]
The office holder reported to different senior flag officers during its existence including the Commander-in-Chief, Home Fleet,[3] the Commander-in-Chief, Western Fleet and finally the Commander-in-Chief Fleet.
On hauling down his flag as Vice-Admiral, Home Fleet Aircraft Carriers, about 27 April 1943, Admiral Lyster was appointed Flag Officer Carrier Training and Administration at HMS Monck (HQ Combined Training, Largs), which was transferred from 1 June 1944 to HMS Faraway, a training establishment & HQ of Flag Officer Carrier Training, at Greenock. He served in that post until 17.03.1945.[6]
Duties may have included (a) being responsible for the Fleet Air Arm afloat (b) ensuring the operational effectiveness of Carrier Task Groups.[3] Probably referring to pre-1967 when Home Fleet still existed.
