POLICY WIRE — Tokyo, Japan — Japan, the United Kingdom, and Italy are advancing plans for the Global Combat Air Program (GCAP), a trilateral initiative to develop and manufacture the next-generation fighter jet. According to sources familiar with the matter, a Mitsubishi Heavy Industries factory in Japan is slated to serve as the central hub for the project’s development and assembly.

The GCAP members are currently deliberating the specific roles each nation will undertake in the design and production phases of the aircraft. The UK is expected to establish its center in Warton, while Italy will set up operations in Turin. The Japanese facility will be responsible for overseeing the overall coordination — and integration of the project.

The collaboration aims to leverage the technological and industrial strengths of each participating country to create a cutting-edge fighter jet capable of meeting future defense requirements. The GCAP represents a significant step in international military cooperation, highlighting the shared commitment of Japan, the UK, and Italy to enhance their defense capabilities through joint efforts.

Further details regarding the timeline, budget, and specific technological features of the fighter jet are yet to be disclosed. The project is anticipated to undergo rigorous testing — and evaluation phases before entering full-scale production.
