No. 11 Squadron RAF No. 11 Squadron of the Royal Flying Corps was formed at Netheravon in Wiltshire on 14 February 1915 for "fighting duties", receiving two seat pusher Vickers Gunbus fighters in June, and deploying to France on 25 July 1915. Since all previous squadrons (Royal Flying Corps or other nations) were reconnaissance or army co-operation units, 11 can make a claim to be the oldest dedicated fighter squadron in the world. The squadron has had the honour of having two Victoria Cross winners serve in the unit.
