The Royal Flying Corps brigades were organizational formations of British military aircraft and personnel during World War I that typically controlled several wings. The air brigade system was introduced into the Royal Flying Corps in late 1915 and initially retained by the Royal Air Force on its establishment on 1 April 1918. Following the Allies' victory later that year the air brigades were disbanded in 1919. Subsequently, the RAF was restructured with commands comprising groups and groups comprising wings without the need for brigades.
