context_page_description: The history of the Royal Air Force, the air force of the United Kingdom, spans a century of British military aviation.
  The RAF was founded on 1 April 1918, towards the end of the First World War by merging the Royal Flying Corps and the Royal Naval Air Service. After the war, the RAF was greatly reduced in size and during the inter-war years was used to "police" the British Empire. The RAF underwent rapid expansion prior to and during the Second World War. During the war it was responsible for the aerial defence of Great Britain, the strategic bombing campaign against Germany and tactical support to the British Army around the world.
  During the Cold War, the main role of the RAF was the defence of the continent of Europe against potential attack by the Soviet Union, including holding the British nuclear deterrent for a number of years. After the end of the Cold War, the RAF took part in several large scale operations, including the Gulf War, the Kosovo War, the War in Afghanistan, and the Iraq War.
context_section_description: While the British were not the first to make use of heavier-than-air military aircraft, the RAF is the world's oldest independent air force: that is, the first air force to become independent of army or navy control. The RAF was founded on 1 April 1918 by the amalgamation of the Royal Flying Corps and the Royal Naval Air Service and was controlled by the British Government Air Ministry which had been established three months earlier. The Royal Flying Corps had been born out of the Air Battalion of the Royal Engineers and was under the control of the British Army. The Royal Naval Air Service was its naval equivalent and was controlled by the Admiralty. The decision to merge the two services and create an independent air force was a response to the events of World War I, the first war in which air power made a significant impact. The creation of the new force was based on the Smuts Report prepared by Field Marshal Jan Smuts for the Imperial War Cabinet on which he served.
  To emphasise the merger of both military and naval aviation in the new service, many of the titles of officers were deliberately chosen to be of a naval character, such as flight lieutenant, wing commander, group captain, and air commodore.
  The newly created RAF was the most powerful air force in the world on its creation, with over 20,000 aircraft and over 300,000 personnel (including the Women's Royal Air Force). The squadrons of the RFC kept their numerals while those of the RNAS were renumbered from 201 onwards.  At the time of the merger, the Navy's air service had 55,066 officers and men, 2,949 aircraft, 103 airships and 126 coastal stations.  The remaining personnel and aircraft came from the RFC. A memorial to the RAF was commissioned after the war in central London. The RAF's last known surviving founder member was the World War I veteran Henry Allingham who died in 2009 aged 113.
  Following the end of World War I and the accompanying British defence cuts, the newly independent (and still temporary) RAF waited nine months to see if it would be retained by the Cabinet. 6,500 officers, all holding temporary commissions or seconded from the Army and Navy, applied for permanent commissions. The Cabinet sanctioned a maximum of 1,500 and the Air Ministry offered 1,065 to the applicants, publishing the first list on 1 August 1919, 75% of them short-term (two to five years). The service as a whole had been reduced in strength to 35,500.
