Note: This is a sub-section of Royal Aircraft Factory.

Twin-engined three-seat multi-purpose aircraft. Powered by two 150 hp R.A.F.5 or two 250 hp Rolls-Royce Mark 1. It was designed by S. J. Waters and Henry Folland.

The F.E.4 was a twin-engine biplane aircraft built by the Royal Aircraft Factory in 1916. Intended as a cannon armed ground-attack aircraft, it was unsuccessful, only two being built.

Shortly after the outbreak of the First World War, the Royal Aircraft Factory began development of the F.E.4, a twin engined aircraft intended for ground attack to be armed with a Coventry Ordnance Works COW auto-cannon.

The design had large two-bay biplane wings, with the longer upper wing fitted with strut-braced extensions that could be folded down during hanger storage. The lower wing was attached to the fuselage halfway up, so the aircraft sat close to the ground. In addition to the conventional landing gear there was a set of wheels mounted to the nose of the fuselage, to prevent damage if it tipped forward. The tailplane was large, with a central fin and two additional vertical surfaces for rudders.

The fuselage housed a crew of three, with the pilot and forward gunner sat in tandem in a large forward cockpit with dual controls. Despite a limited field of fire caused by being sat behind the pilot, the forward gunner was to be armed with two Lewis guns and a COW gun. A rear gunner sat behind the wings in a second cockpit.

The two engines, RAF 5s, were installed just above the lower wing in a pusher configuration.

The first F.E.4 was built in March 1916, and the second in July 1916. The second aircraft was fitted with Rolls-Royce Eagle engines, and did not include the rear cockpit. The intention was to put the rear gunner in an elevated section mounted above the wings, accessible by a ladder and hole in the upper wing, but this was never built.

Both aircraft were tested at Central Flying School, Upavon beginning in May 1916, but neither performed well.

In September 1916 the second F.E.4 was fitted with bomb-carrying equipment for further testing. Designs were created for engine upgrades, intended for RAF 3As, RAF 4As or RAF 4Bs, but no work was actually done.

They were still extant in July 1917 but were eventually broken up.
