It has been reported in Japan that Tokyo is finalising its policy on how to jointly develop the engine of its upcoming F-X fighter with Britain.
The Mitsubishi F-X is a sixth-generation stealth fighter in development for Japan and it is the nation first domestically developed stealth fighter jet. It is hoped that the aircraft will replace the Mitsubishi F-2, a design based on the F-16, by the mid–2030s.
According to the report here:
“Several government officials have revealed. The government wants to solidify the framework of cooperation by March next year. A prototype will be manufactured from 2026, with the aim of starting flight tests in the 2030s. The UK will participate in the development of the air intake for jet engines and the area near the exhaust. These parts also have importance closely related to the stealth performance of the aircraft and the overall shape.”
It was also previously reported that Rolls-Royce will partner with Japan’s IHI Corporation. According to Asahi here.
“Anonymous Japanese officials told the news outlet that Japanese Prime Minister Suga spoke on the issue with British Prime Minister Johnson during the G7 summit last month. At the end of June, officials from Japan’s Defense Ministry travelled to Britain for talks on the issue. Britain’s Rolls Royce is currently involved in the Tempest program as well.”
The report adds:
“According to several Japanese government officials, an exchange on joint engine development was held at a meeting between Prime Ministers Yoshihide Suga and Johnson at the G7 Summit held in the United Kingdom in June.”
