This will be a project to keep an eye on. The US decided the technology in the F-22 is not something that should be sold, so Japan decided to work on their own stealth fighter. It’s called the X-2.
The X-2 is more of a proof of concept right now, but it’s already flown. This will be interesting to watch over the next few years. The implications for the balance of power in Asia, export sales, and other factors will be fascinating.
