About 100 were built for the Royal Flying Corps but saw only limited use as it was designed for a larger engine which was not available when production commenced and it did not meet performance expectations.

The F.B.14 was a conventional single-bay biplane with two tandem open cockpits and a fixed tailskid landing gear.

A more reliable engine was tested, but the 120 hp (90 kW) Beardmore did not help meet the performance required.

The Rolls-Royce powered F.B.14D, while being used for testing of an experimental gunsight at Orfordness on 22 July 1917, engaged in a German air raid and claimed an unconfirmed shoot-down of a Gotha bomber off Zeebrugge.
