The Global Combat Air Programme (GCAP) is a major international defence initiative bringing together the United Kingdom, Italy and Japan to develop a next-generation combat air system. Announced in 2022, the programme aims to deliver a new fighter aircraft by 2035, replacing existing platforms such as the Eurofighter Typhoon and Japan's Mitsubishi F-2.

At its core, GCAP is designed to ensure that partner nations maintain a cutting-edge combat air capability in an increasingly complex global security environment. As threats evolve, modern air forces require more advanced, connected and adaptable systems. GCAP brings together the military, industrial and technological strengths of all three nations to meet this challenge, while also strengthening long-term defence cooperation.
