The Vickers F.B.5 (Fighting Biplane 5) (known as the "Gunbus") was a British two-seat pusher military biplane of the First World War.Armed with a single .303 in (7.7 mm) Lewis gun operated by the observer in the front of the nacelle, it was the first aircraft purpose-built for air-to-air combat to see service, making it the world's first operational fighter aircraft.
The design was a development of the earlier Vickers F.B.12 prototypes; [2] and was a two-bay biplane with a high-mounted nacelle for the pilot and an initial armament of two .303 in (7.7 mm) Lewis Guns. Behind this was a water-cooled 200 hp (150 kW) Hispano-Suiza engine driving the propeller.
The Vickers response, the F.B.11, designed by R. L. Howard-Flanders, was a large, single-bay, biplane of tractor layout. The pilot and one gunner sat in separate but closely spaced cockpits under the trailing edge of the upper wing, while a second gunner sat in a nacelle, or "fighting top", attached to, and extending forward of the upper wing.

At the start of the First World War, Vickers entered into a partnership with the Hart Engine Company to develop a 150 hp (110 kW) nine-cylinder radial engine designed by Hart. This engine was planned to power a number of new designs by Vickers, the first of which was a small single-engine pusher biplane fighter , the F.B.12 .
