The British Air Force, officially known as the Royal Air Force (RAF), is the aerial warfare service branch of the United Kingdom. Established in 1918, it was the first independent air force in the world. The RAF's primary roles include defending the UK and its interests, providing air support for ground forces, and conducting humanitarian missions. The RAF operates a variety of aircraft, including fighter jets like the Eurofighter Typhoon and transport planes such as the A400M Atlas. It plays a crucial role in international peacekeeping and disaster relief efforts, often collaborating with other branches of the military and allied nations.
