Construcciones Aeronáuticas SA (CASA) was founded by José Ortiz-Echagüe in 1923 and began work on a factory in Getafe in May 1924, building Breguet aircraft under license.

This aircraft was piloted by Captains Ignacio Jiménez and Francisco Iglesias and covered 6746 km in 43 hours 50 minutes.

The other was the Breguet XIX Super Bidon, named Cuatro Vientos (Four Winds); it was flown by Mariano Barberán and Joaquín Collar Serra to Havana in Cuba in 1933.

CASA manufactured the Russian Polikarpov I-15 biplane fighter, producing 287 aircraft before the end of the civil war.

In 1945 CASA opened a factory in Madrid dedicated to manufacturing the parts and sub-assemblies of their various aircraft and those that they had contracts to repair and overhaul.

In 1946 CASA re-established the Projects Office and resumed the design of aircraft based on the firm's proprietary technology.

In 1977, CASA was awarded the contract to design and build the C-101, a trainer and attack aircraft for the Spanish Air Force.

CASA has been a part of EADS, the European aerospace corporation, with Aérospatiale-Matra of France, Dornier GmbH and DASA of Germany since 1999.

EADS was formed in July, 2000 following the merger of Aerospatiale Matra of France, DaimlerChrysler Aerospace of Germany and Construcciones Aeronáuticas S.A. from Spain.

In July 2001 EADS-CASA Military Aircraft marked the beginning of the Eurofighter Typhoon Final Assembly Phase at Getafe.
