By 1957, Fiat Aviazione was in the process of establishing the first production line for the G.91 at their facility at Turin-Aeritalia Airport, Piedmont, Italy. In total, Fiat constructed 174 G.91s of various variants for Italy, along with an additional 144 G.91 R/3 variants for West Germany (including 50 that had been ordered and then cancelled by Greece and Turkey). The first order was for 50 aircraft from Aeritalia, then Dornier and other German firms had an order for 232 machines, which was later increased to 294. The "Luftwaffe" (German Air Force) also bought 44 G-91T/3 two-seat trainers and another 22 were produced in Germany, ending production in 1972.
