Yeah, but the Saudis turned against China, ran off with the technology and became America’s core ally instead. Don’t think China would touch a hot plate twice.
If the FC-31 is as good as the F-35 or better (as the redesign indicates it will be), then it is FAR to sensitive to sell to any country that is not completely aligned with China.
Selling artillery pieces and ancient drones is one thing, selling state of the art stealth fighters is a whole another matter.
Besides if even the F-35 is criticized for being expensive, how can the FC-31 be justified to foreign buyers? Last time Shenyang wanted 70 million $ apiece + R&D costs to finish it, and that was before WS-19 and the redesign. For reference, non VTOL F-35s go for 80 million $. Maybe the rich Saudis will take it, but again they can’t be trusted with it.
Maybe Shenyang can utterly gut it and make a monkey model that’s safe to sell with a reasonable price tag, but that would be almost a new plane, and also a bit of an insult to the original plane (?)
