No. 41 Squadron of the Royal Air Force is the RAF's Typhoon Test and Evaluation Squadron ("TES"), based at RAF Coningsby, Lincolnshire. Its official title is "41 TES". The squadron was formed in 1916 during First World War as part of the Royal Flying Corps and served on the Western Front as a ground attack and fighter squadron. Disbanded in 1919 as part of the post-war draw down, No. 41 Squadron was re-formed as an RAF squadron in 1923 and remained on home service until 1935 when it was deployed to Aden during the Abyssinian crisis.
