The direct predecessor of the Ministry of the Air was the Ministry of National Defense, created in 1938 during the first government of Francisco Franco, under the then commander of the Army of the North [es], Fidel Dávila Arrondo.[1] The three branches of the Armed Forces (Army, Navy and Air Force) were grouped under its control.[2] The Ministry of the Air was created in the second government of Francisco Franco; it was defined and regulated by Law of 8 August 1939,[2] whose organization and functions were delimited by Decree of 1 September 1939. General Juan Yagüe was appointed Minister, with Fernando Barron as Undersecretary.[3]
After the end of the Civil War, Yagüe intended to build a new Air Force out of the Aviación Nacional with the help of Nazi Germany and Fascist Italy, and with the clear intention of participating in World War II on the side of the Axis powers.[4] At the beginning of World War II the new Air Force had 14 regiments and 3 groups,[5] composed in turn by 172 fighters and 164 bombers of different types, along with 82 assisting planes and 75 other devices of different types captured from the Spanish Republican Air Force.[6] The reports issued by the General Staff, however, left in evidence the bad state in which the airplanes were, the lack of spare parts and fuel.[7] In the end, the project to expand the Air Force was a failure given the situation in the country, and Yagüe was dismissed and replaced by General Juan Vigón.[4] Since 1940, different locations in Madrid were searched for the future headquarters of the Ministry, and after several options a site in the district of Moncloa-Aravaca was chosen. The lots are acquired by the City Council of Madrid, under then Mayor of MadridAlberto Alcocer y Ribacoba; General Vigón instructed architect Luis Gutiérrez Soto on the renovation of the area and the design of the new building. Although the building was not completed until 1958, it was already fulfilling its mission in 1954.
