The United Kingdom, Italy, and Japan have entered into an international treaty to develop a stealth fighter with supersonic capability and a radar able to provide 10,000 times more data than current systems, the governments announced Thursday.
The agreement was signed by U.K. Defense Secretary Grant Shapps, Japan defense minister Minoru Kihara, and Italy defense minister Guido Crosetto in Tokyo, coming one year after the formation of the Global Combat Air Program (GCAP).
