Japan, the United Kingdom, and Italy have formally established the international organization GIGO to oversee their joint development of a next-generation fighter jet, known as the Global Combat Air Program (GCAP). The organization is headquartered in southern England, with former Japanese Defense Councilor Masaomi Oka appointed as its first chief executive officer. The three countries are accelerating the project, with a trilateral videoconference involving their defense ministers emphasizing expedited progress. While Saudi Arabia has been considered a potential partner, its inclusion is contingent on the project's advancement and resolution of outstanding issues. However, recent statements from a BAE Systems executive indicate that the likelihood of new partners joining the UK-Italian-Japanese fighter jet project is diminishing. Meanwhile, BAE Systems is advancing its own next-generation Tempest fighter jet program, with over 3,500 personnel involved, including 300 UK companies and more than 100 firms on the demonstrator. The Tempest demonstrator, a large supersonic crewed combat aircraft developed in partnership with Rolls-Royce, MBDA UK, and the UK Ministry of Defence, has accumulated more than 300 flight hours in simulated environments. BAE is also optimistic about securing orders for 150 additional Eurofighter Typhoon jets, with potential buyers including Turkey, Qatar, and Saudi Arabia.
