Ernesto Horacio Crespo is an Argentine retired Brigadier General(Lieutenant General) and former Chief of Staff of the Argentine Air Force.
In 1982, Crespo, who was the commander of the Fourth Air Force Brigade at the time, was commanded to create, deploy, and command the Fuerza Aérea Sur (English: Southern Air Force); the military organization that would control both Air Force and Argentine Navy air units that would later take part in the Falklands War (Spanish: Guerra de las Malvinas).
From 1985 to 1989 he acted as Chief of Staff of the Air Force under presidency of Raúl Alfonsín. During the Carapintadas conflict within the Argentine Army, the Air Force under his command, stood in defence of the democratic government.
During his mandate, the Argentinian Air Force developed the Condor missile, which was later discontinued in the early 1990s during the Carlos Menem presidency because of political pressure from the United States.
