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.

[7] Second Lieutenant G. S. M. Insall was awarded a Victoria Cross for an action on 7 November 1915 in which he forced down and destroyed a German Aviatik observation aircraft.

[8] The Gunbus was already obsolete however, and was initially supplemented by a mixture of Bristol Scouts and Nieuport 16s until replaced by the Royal Aircraft Factory F.E.2b of similar layout, but slightly higher performance, in June 1916.

[9] These in turn were replaced by Bristol Fighters in August 1917, these being used both for offensive patrols over German-held territory and for ground attack for the remainder of the war.

Among them were Victoria Cross winner Lionel Rees, as well as Andrew Edward McKeever, John Stanley Chick, Eugene Coler, Albert Ball VC, Frederick Libby, Ronald Maudit, John Quested, Herbert Sellars, Donald Beard, Stephen Price and Hugh Hay Thomas Frederick Stephenson.

[11] The twin Eagles on the Squadron's crest, awarded in May 1937, represent the two-seated fighters operated in the First World War.

In April 1924, these were replaced by the Fairey Fawn despite the fact that they offered little improvement in performance over the DH.9A, moving with them to RAF Netheravon in May that year.

The unpopular Fawns were replaced by Hawker Horsleys in November 1926, in use until December 1928, when the squadron handed the Horsleys to 100 Squadron and was posted to Risalpur in India (now in Pakistan), flying Westland Wapitis in Army co-operation and carrying out punitive air raids against rebelling tribal forces.

[14] The squadron received Blenheim I monoplane bombers in July 1939, moving to Singapore the next month, just before the outbreak of World War II in Europe.

[10] In April 1940 the squadron moved to India, and was briefly based at Karachi before it was ordered to transfer to Aden due to the increasing likelihood of war with Italy.

Personnel of the Larissa-based squadrons spent the rest of the night rescuing people trapped in collapsed buildings.

During 1943, the Squadron re-equipped with Hurricanes and moved to Burma in the ground attack role, supporting the Fourteenth Army.

Javelins replaced the Meteors one year later and the Squadron was based at RAF Geilenkirchen, in West Germany, equipped with this type until another disbandment in 1966.
