had a total of 1,583 F.2Bs in squadron service; it was in service with six reconnaissance squadrons stationed in France and five Home Defence squadrons, while further squadrons operating the type in the Middle East and Italy. A total of 5,329 aircraft were eventually constructed, mostly by Bristol but also by Standard Motors, Armstrong Whitworth and even the Cunard Steamship Company. According to Bruce, by the time of the Armistice of 11 November 1918, the "Bristol Fighter ended the war supreme in its class". Postwar Following the end of the war, the F.2B Fighter was soon adopted by the RAF as its standard army cooperation machine. The type continued to operate in army cooperation and light bombing roles in the British Empire, in particular the Middle East and India. In line with this role, which led to its use in a hot climate, Bristol introduced models of the Fighter equipped with 'tropical' radiators and provision for desert equipment. There had also been considerations made into deploying the Fighter as a carrier-based aircraft, which led to an engineless airframe participating in immersion trials in November 1918 and an aircraft being used in deck landing tests, reportedly on board . It was not until 1932 that the F.2B was withdrawn from RAF service, the last "Brisfit" unit being 20 Squadron stationed in India. The type lasted a further three years in New Zealand. Surplus aircraft were allocated to ADC Aircraft, a British company established to act as a seller for wartime aircraft, which passed on large quantities of Fighters to other nations, normally to military operators. Bristol also continued to manufacture and refurbish the type for some time. During the 1920s Bristol proceeded to develop and introduce numerous variants and derivatives of the Fighter, typically capable of carrying higher loads, revised tail units and strengthened undercarriages. The F.2B Fighter was adopted by the New Zealand Permanent Air Force and the Royal Australian Air Force (RAAF), as well as by the air forces of Belgium, Canada, Ireland, Greece, Mexico, Norway, Peru, Spain and Sweden. According to Bruce, relatively few Fighters entered service with the air forces of the various Commonwealth nations, greater quantities having been sold to other nations. Belgium purchased several from ADC Aircraft, and later arranged to produce the Fighter under licence at Sociétés Anonyme Belge de Constructions Aéronautiques (SABCA). In 1920 Poland bought 106 Bristol Fighters (104 with Hispano-Suiza 300
