The Su-80 program was supposed to start in the late 1990s, but due to lack of funds, it was postponed for several years.
The first model of the turboprop transporter Sukhoi S-80 was shown at the 46th Paris International Air and Space Show, 2005.
Two General Electric CT7-9B turboprop engines are housed in bays at the front of the tail booms.
The four pre-series aircraft were of a short-fuselage design, while the fifth, sixth and seventh prototypes were stretched by 1.4 m (4 ft 7 in) allowing an extra row of passenger seats.
