No.11 Group was a part of which air force that emerged as the largest air force in the world in 1918?
No. 11 Group RAF No. 11 Group was a group in the Royal Air Force for various periods in the 20th century, finally disbanding in 1996. Its most famous service was during 1940 when it defended London and the south-east against the attacks of the Luftwaffe during the Battle of Britain.
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.
