Not only could an operational FC-31 help fill the ranks of PLAAF medium and light fighter squadrons, but it could also be adapted for China’s emerging CATOBAR aircraft carrierprogram. This would give China a stealthy fighter that can project power far from the Chinese mainland.
If this redesign proves fruitful, it's all but guaranteed China will move to export the FC-31 to anyone with the cash to buy it. Many countries either can't afford, or are not allowed to buy, the Lockheed Martin F-35 from the US. These nations could turn to China and the FC-31 to provide them with a “poor man’s” Joint Strike Fighter. Pakistan, in particular, is a very ripe candidate to join the FC-31 program early on–especially as new aircraft join the Indian Air Force’s fleet, including the PAK-FA based on Russia’s stealthy T-50 fighter.
The FC-31 appeared for the first time over four years ago, and the fact that already moved from “YF” configuration to a near production configuration is telling. It shows how committed China is to developing multiple stealth fighters as part of a high-low capability mix, and to take a larger share of the fighter export market abroad.
