Comac C939

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.

Design
In May 2024, the designs for the C939 were reported to have a capacity of 400 seats and a range of 7,000 nmi. The C939 is expected to be a twinjet.

Development
In June 2011, Comac was studying the 290-seat C929 and 390-seat C939 wide-body aircraft. Preliminary plans for the C939 were mentioned in Chinese newspapers in 2015 and 2017.

In May 2024, South China Morning Post reported that the Comac has initiated work on the C939.
