China’s official military forum mil.huanqiu.com says in its two reports yesterday that China’s new version of J-31 (also known as FC-31) stealth fighter jet conducted its maiden flight yesterday. It provides the above 7 web users’ photos including two photos of comparison between the old and new versions.
We see in the comparison in the change of the shape of horizontal tail, but mil.huanqiu.com says that there has also been changes to optimize its maneuverability, stealth and loading capacity.
It says that according to information provided by the producer, the warplane is 17.3 meters long and 4.8 meters high with a wingspan of 11.5 meters. Its ceiling is 16,000 meters, combat radius, 1,250 km, maximum horizontal speed, 1,400 km/h and maximum takeoff weight, 28,000 kg.
There is information that it is equipped with active phased array radar, helmet-mounted display and sight system, infrared search and track system, integrated electro-optical targeting system and a single display-panel cockpit.
If the warplane satisfies the standards published by the producer, it will be an excellent high cost-effective medium-sized stealth fighter jet with large range, heavy load of ammunition and multi-function.
J-31 is the only fighter jet in world market that has no generation gap with F-35. As it is much cheaper, it will grab a large market share from F-35.
