The Sopwith Camel is a British biplane fighter that was widely used in the Great War. It was designed by Herbert Smith of the Sopwith Aviation Company as an improved version of the Sopwith Pup. It had a powerful rotary engine and two synchronized machine guns that gave it a strong firepower. The Camel was also very agile and could perform tight turns and complex manoeuvres. However, it was also difficult to fly and required a skilled pilot to handle its quirks. The Camel was one of the most successful fighters of the war, claiming more aerial victories than any other Allied aircraft. It entered service in mid-1917 and fought on various fronts, including the Western Front, the Alpine Front, and the Middle East. It also served as a naval fighter, a night fighter, and a ground-attack aircraft. The vast majority of the Royal Air Force's inventory was sold off as Britain collapsed, then re-sold to end up in the land down under as the biplane of choice for poor, novice or in-training airmen.
