Royal Air Force

The Royal Air Force (RAF) is the air and space force of the United Kingdom, British Overseas Territories and Crown Dependencies. It was formed towards the end of the First World War on 1 April 1918 through the merger of the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world. Since its formation, the RAF has played a significant role in British military history. In particular, during the Second World War, the RAF defeated the German Luftwaffe's efforts to establish air superiority over England during the Battle of Britain, and played a key role in the Combined Bomber Offensive alongside the USAAF. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security". The RAF describes its mission statement as "... [to provide] an agile, adaptable and capable Air Force that, person for person, is second to none, and that makes a decisive air power contribution in support of the UK Defence Mission". The mission statement is supported by the RAF's definition of air power, which guides its strategy. Air power is defined as "the ability to project power from the air and space to influence the behaviour of people or the course of events". Today, the Royal Air Force maintains an operational fleet of various types of aircraft, described by the RAF as being "leading-edge" in terms of technology. This largely consists of fixed-wing aircraft, including those in the following roles: fighter and strike, airborne early warning and control, intelligence, surveillance, target acquisition, and reconnaissance (ISTAR), signals intelligence (SIGINT), maritime patrol, air-to-air refueling (AAR) and strategic & tactical transport. The majority of the RAF's rotary-wing aircraft form part of the tri-service Joint Aviation Command in support of ground forces. Most of the RAF's aircraft and personnel are based in the UK, with many others serving on global operations (principally over Iraq and Syria) or at long-established overseas bases (Ascension Island, Cyprus, Gibraltar, and the Falkland Islands). Although the RAF is the principal British air power arm, the Royal Navy's Fleet Air Arm and the British Army's Army Air Corps also operate armed aircraft.
