The Frigate Ecojet (in Russian: Фрегат Экоджет, transliterated as Fregat Ekodzhet), is a program for the development of a new wide-body medium-haul civil aircraft using new aerodynamic, and design configurations.The primary goal of the Frigate Ecojet program was the development of a range of new wide-body medium-haul aircraft, intended to be operational by 2018.Sergey Grachev, director of marketing sales for the Frigate Ecojet stated 'It is impossible to develop and create this kind of aircraft here'.[5] When moving to Europe the company will also seek to harmonize cockpit design with a competitor to reduce pilot training costs.In August 2017, initially powered by 177–226 kN (40,000–51,000 lbf) PD-18R or PS-90A20 but lacking modern engines, the twinjet was modified into a Freejet four-engined design powered by modern 12–14 tf (26,000–31,000 lbf) engines introduced for the single-aisle market: the Irkut MC-21's Aviadvigatel PD-14, the Pratt & Whitney PW1100G or the CFM International LEAP powering the A320neo and the B737 MAX, losing a little in aerodynamics and weight and raising the maximum take-off weight from 130 to 140 t (290,000 to 310,000 lb) for a range of 3,500 km (1,900 nmi) for 300 passengers in an all-economy 10-abreast triple-aisle cabin, increasing to 4,680 km (2,530 nmi) with 244 passengers; it has a wingspan of 48.53 m (159.2 ft) and over length of 49.65 m (162.9 ft) with eight emergency exits.
