Permission was granted to form the Escuela Militar de Mecánicos de Aviación on 12 March 1921. This unit evolved into the branch that is called the Fuerza Aérea de Guatemala (FAG) today. On 30 June 1929, the Cuerpo de Aviación Militar de Guatemala was formed, which was renamed Cuerpo de Aeronáutica Militar in 1936. The FAG is a relatively small air force. It has relied mostly on US aircraft types during its history. The F-51 Mustang, C-47 Dakota, T-33 and Huey are typical examples of this. Some of these aircraft still serve the FAG today, the C-47 Dakota for example, albeit in the Turboprop variant. The FAG has no jet aircraft, and PC-7s and T-35s are used for training. A single Arava carries out transport augmenting the Dakotas mentioned before. A few modernization programme have been started in the 2000s although this has so far not led to delivery of new armed aircraft, although both Super Tucanos and IA-63 Pampas have been mentioned. With a number of Cessna 208s and a DHC-6-400 Twin Otter, mainly light transport aircraft have been acquired the last few years.
