Bristol F2B serial J7624 of A Flight 2 Squadron, Royal Flying Corps
The Bristol F.2 Fighter was a British two-seat biplane fighter and reconnaissance aircraft of the First World War flown by the Royal Flying Corps. It is often simply called the Bristol Fighter or popularly the “Brisfit” or “Biff”. Despite being a two-seater, the F.2B proved to be an agile aircraft that was able to hold its own against opposing single-seat fighters. Having overcome a disastrous start to its career, the F.2B’s solid design ensured that it remained in military service into the 1930s, and surplus aircraft were popular in civil aviation.
Only 52 F.2As were produced before production switched to what became the definitive Bristol Fighter, the Bristol Type 14 F.2B which had first flown on 25 October 1916. The first 150 or so were powered by the Falcon I or Falcon II engine but the remainder were equipped with the 275 hp (205 kW) Falcon III engine and could reach a maximum speed of 123 mph (198 km/h). The F.2B was over 10 mph (16 km/h) faster than the F.2A and was three minutes faster at reaching 10,000 ft (3,000 m).
F.2Bs often carried a second Lewis gun on the rear cockpit mounting, although observers found the weight of the twin Lewis gun mounting difficult to handle in the high altitudes at which combat increasingly took place in the last year of the war. A number of attempts were made to add forward firing Lewis guns on a Foster mounting or similar on the upper wing – either instead of, or in addition to the Vickers gun. Unfortunately this caused interference with the pilot’s compass, which was mounted on the trailing edge of the upper wing. Some F.2Bs were fitted with a Lewis gun offset to starboard to minimise this effect
