In the 1960s, new aircraft were incorporated, including the F-86F Sabre jet fighter and the Douglas A-4 Skyhawk mainly used for ground-attack. U.S. Air Force Major Manuel J. Fernandez, a Spanish-speaking Sabre ace who shot down 14 enemy aircraft in the Korean War on board that aircraft, was dispatched to the Mendoza airbase from 1960–1962 to personally train Argentine pilots flying the model. During the 1970s, the Air Force re-equipped itself with modern aircraft, including Mirage III interceptors, IAI Dagger multi-role fighters (Ex-Israeli, comparable to the Mirage V), and C-130 Hercules cargo planes. A counter-insurgency airplane, the Pucará, was also manufactured and used in substantial numbers. The Air Force also had an important role in the 1976 coup which lead to a military dictatorship that lasted until 1983.
