The aircraft was first flown on 5 January 1925 and delivered to the Marine Aircraft Experimental Establishment at Felixstowe on 14 March, where it was subjected to a series of strenuous tests, including dropping the aircraft onto the water by stalling it at a height of 30 ft (9 m): the aircraft withstood all trials, and after a year an inspection revealed only negligible corrosion.

Approximately 100 Felixstowe F.3s were produced before the end of the war, including 18 built at Malta Dockyard.
Three Valentia prototypes were built by the Vickers Company at their Barrow works (Walney Island perhaps), having been ordered in May 1918 as a potential replacement for the Felixstowe F.5.
