Italy, Japan, and the United Kingdom have solidified their aviation partnership by signing a £4.6 billion (approximately $6.1 billion) contract under the next‑generation combat aircraft programme, the Global Combat Air Programme (GCAP). This 18‑month agreement, led by prime contractor Edgewing, represents a critical milestone in the design and engineering activities for the new‑generation stealth fighter jet, which is slated to enter service in 2035.
Meanwhile, a significant development has occurred regarding the program’s geopolitical reach. The parties have reached an agreement for Canada to join the GCAP program with observer status.
Canada Officially Joins GCAP as an Observer
Meeting in London, Italian Minister of Defence Guido Crosetto, Japanese Minister of Defense KOIZUMI Shinjirō, UK Secretary of State for Defence Wes Streeting, and Canadian Minister of National Defence David J. McGuinty issued a joint statement formalizing Canada’s participation in the program under observer status.
Observer status will provide Canada with deeper insights into the GCAP, enabling the country to closely understand the program’s governance structure, capabilities, industrial framework, relevant security requirements, and broader partnership opportunities. Meanwhile, Italy, Japan, and the United Kingdom view this step as a critical milestone in aligning strategic priorities and strengthening global security toward future combat air power objectives.
Programme Design Gaining Momentum

The £4.6 billion contract ensures the completion of the programme’s advanced concept and assessment phase, while guaranteeing the continuity of the joint detailed design and development processes. Awarded by the GCAP Agency, which manages the programme on behalf of the three governments, this authorisation directly supports the engineering work of Edgewing, the programme’s design authority. Further details on the programme’s core design contract can be found in our previous coverage.
The £4.6 billion (approximately $6.1 billion) funding covers an 18‑month schedule under Edgewing’s prime contractorship. Conducted jointly by Italy, Japan, and the UK, the programme is focused on developing a next‑generation stealth fighter jet, with entry into service targeted for 2035.
GCAP Agency Chief Executive Masami Oka emphasised that the contract marks a significant step toward the programme’s objectives. “This funding secures the future of GCAP,” Oka said. “The programme contributes to cost‑sharing, joint technology development, and the creation of high‑skilled employment across all three nations.”
Edgewing CEO Marco Zoff highlighted the success of the model: “This contract is a testament to the trust that the three nations and our partners at the GCAP Agency have placed in us. As a single engineering prime contractor working on behalf of all three national industries, we continue to execute this new phase of the programme.”
Strategic Defence Industry Collaboration
Launched in 2022, GCAP stands out as a project that supports the defence industries of the participating countries. The programme aims to advance design and manufacturing capabilities, employment, and intellectual property generation. Subcontractors such as the GCAP Electronics Evolution (G2E) Consortium are also continuing their work on the aircraft’s advanced sensing and communication systems.
