The AMX "Ghibli" single-engine ground attack aircraft was the result of a collaborative project between the Italian and Brazilian aviation industries. The project was initiated in the 1980s to replace the dated Italian Air Forces Fiat G-91Y fighter-bomber. The Brazilian Air Force also needed to replace their Italian made MB-326s. The AMX had an aerodynamic lay-out characterized by a high swept wing, and with its Rolls-Royce Spey 807 engine could attain a maximum speed of 1,000 km / h. The Italian version was armed with a 20 mm M61 cannon and could carry an offensive payload of 3,800 kg. The two-seat AMX-T version was established and developed as an advanced training aircraft, but it could also be deployed on combat missions in a ground attack and close support role. Italy acquired 26 AXM-Ts for the Italian Air Force.
