The Comac C939 is a planned long-range wide-body twinjet airliner family being developed by Chinese Comac as a competitor to the Boeing 777 and Airbus A350. It is designed to be larger than the other two models in its domestically produced aircraft line: the Comac C919 and Comac C929.
In May 2024, the designs for the C939 were reported to have a capacity of 400 seats and a range of 7000nmi.[1] The C939 is expected to be a twinjet.
In June 2011, Comac was studying the 290-seat C929 and 390-seat C939 wide-body aircraft.[2] Preliminary plans for the C939 were mentioned in Chinese newspapers in 2015 and 2017.[3]
In May 2024, South China Morning Post reported that the Comac has initiated work on the C939.[1] [4]
