[1] In early 1941, the Royal Navy made provisions for seaplane flying training at Lawrenny Ferry.

[1] 764 Seaplane Training Squadron used the facilities, which included a main hangar, three concrete aircraft pens, an eighteen-foot (5.5 m) slipway and fuel storage, before moving permanently from RAF Pembroke Dock.

The base officially became a Royal Naval Air Station under the control of RNAS Lee-on-Solent (HMS Daedalus) and played a key role in Seaplane Flying Training Part II, which included Seaplane conversion and gunnery courses.

[1] However, with the decline in training demand, the base was reduced to Care and Maintenance status in November 1943, with only three months’ notice required to re-commission and resume flying.

[1] The need for Seaplane Training had diminished by the middle of 1943 and eventually 764 NAS was officially disbanded at RNAS Lawrenny Ferry on 7 November 1943.
