The present-day command structure of the Spanish Air Force issued from a Government decree dated 2d October 1935 of the Spanish Republican Government that placed the Dirección General de Aeronáutica under the authority of a specific ministry, known then as the War Ministry, Ministerio de la Guerra, instead of being under the Presidencia del Gobierno. Following that decree, the Air Force regional units became restructured in 1936. Accordingly, the Spanish Navy-based Escuadra model was replaced by Región Militar divisions which are still operative today. Nowadays the Spanish Air Force is still under a separate ministry, the Ministerio de Defensa.
