In mid-March 1972, A-4Q Skyhawks began flying in Argentina. This was a true weapons system, introducing things like the air-to-air missile, resupply, photographic reconnaissance, etc. for the first time. And an on-board operational capacity, unique in the region.
The author Jorge Núñez Padin, based on an exhaustive investigation of a large number of American, English and obviously Argentine documents, describes the process of selection and commissioning of this aircraft.
