During the mid-1980s, Embraer was working on the Short Tucano alongside a new version designated the EMB-312G1, carrying the same Garrett engine. The EMB-312G1 prototype flew for the first time in July 1986. However, the project was dropped because the Brazilian Air Force was not interested in it. Nonetheless, the lessons from recent combat use of the aircraft in Peru and Venezuela led Embraer to keep up the studies. Besides a trainer, it researched a helicopter attack version designated "helicopter killer" or EMB-312H. The study was stimulated by the unsuccessful bid for the US military Joint Primary Aircraft Training System program. A proof-of-concept prototype flew for the first time in September 1991. The aircraft features a 1.37 m (4.5 ft) fuselage extension with the addition of sections before and after of the cockpit to restore its center of gravity and stability, a strengthened airframe, cockpit pressurization, and stretched nose to house the more powerful PT6A-67R (1,424 shp or 1,062 kW) engine. Two new prototypes with the PT6A-68A (1,250 shp or 930 kW) engine were built in 1993. The second prototype flew for the first time in May 1993 and the third prototype flew in October 1993.

Following a world trend towards the replacement of jet trainers with lower-cost, turboprop trainers, in July 1990 the French Air Force initially ordered 80 slightly modified variants, designated as the EMB-312F.
Within 21 months of the contract having been signed, the first prototype took flight on 16 August 1980, bearing the FAB serial 1300.
