Planes ID'd, Blue & Grey aircraft colours are more likely to be mid-late war.
(From Wiki:) The first Barracudas entered service on 10 January 1943 with 827 Squadron and were deployed in the North Atlantic. A total of 24 front-line squadrons were eventually equipped with Barracudas. The Barracuda first saw action with 810 Squadron aboard HMS Illustrious off the coast of Norway in July 1943 before deploying to the Mediterranean to support the Salerno landings.[11] The following year they entered service in the Pacific Theatre.
The Royal Air Force used the Barracuda Mk II, initially in 1943 with No. 567 Sqn. at RAF Detling. In 1944, similar models went to 667 Sqn. (RAF Gosport), 679 Sqn. (RAF Ipswich) and 691 Sqn.(RAF Roborough). All the aircraft were withdrawn between March and July 1945.[12][13]
Probably a FAA base, but where?
Berets wrong for RAF erks, RN more likely.
Any ID/caption/website from the original source?
The tie-downs on the slipway by the first 2 planes are interesting, btw...
