The Spanish Air Force as a separated branch of the Spanish Armed Forces was officially established on 7 October 1939, after the Spanish Civil War. Francisco Franco as head of Spanish state and commander-in-chief named himself 1st captain general of the Spanish Air Force. General Ángel Salas Larrazábal, a veteran fighter pilot, has been the only honorary Air captain general (1991-1994).
