UK, Italy and Japan Award £4.6 Billion GCAP Development Contract to Edgewing

The trinational GCAP Agency on July 3 awarded a £4.6 billion ($6.1 billion), 18-month contract to Edgewing, the BAE Systems-Leonardo-JAIEC joint venture, to complete concept work and begin detailed design of the sixth-generation fighter targeted for service entry in 2035.

The United Kingdom, Italy and Japan on July 3, 2026, awarded a £4.6 billion (approximately $6.1 billion) development contract for the Global Combat Air Programme (GCAP), the sixth-generation fighter the three nations intend to field by 2035. The contract was placed by the GCAP Agency, the intergovernmental body that manages the program on behalf of the three governments, with Edgewing, the program's trinational industrial prime contractor.

The 18-month contract covers completion of the aircraft's advanced concept and assessment phase and the start of joint detailed design and development, funding what officials described as key design and engineering activity. It replaces an interim arrangement worth £686 million, awarded in April 2026, which expired on June 30.

"With this long-term funding, the future of GCAP has never been more assured," said Masami Oka, chief executive of the GCAP Agency, adding that the contract "represents trust placed in us by all three nations." UK Defence Procurement Minister Luke Pollard said the milestone "strengthens our partnership with international allies" and supports thousands of highly skilled jobs across the UK.

Edgewing, which acts as prime contractor and design authority for the fighter, is a joint venture of three national champions:

• BAE Systems (United Kingdom)
• Leonardo (Italy)
• Japan Aircraft Industrial Enhancement Co. Ltd. (JAIEC), the Japanese industry vehicle led by Mitsubishi Heavy Industries

Edgewing chief executive Marco Zoff said the program's momentum "is being driven by our disruptive new model of defence collaboration," with a single unified engineering prime spanning the three countries. Alongside the airframe work, a trinational sensing and communications consortium (G2E) is developing the aircraft's integrated sensor suite, while a separate power and propulsion consortium is responsible for an engine intended to give the fighter extended range and persistence.

Launched in 2022, GCAP is designed to replace the Eurofighter Typhoon in service with the Royal Air Force and the Italian Air Force, and the Mitsubishi F-2 flown by the Japan Air Self-Defense Force. The award follows the UK's Defence Investment Plan, published the previous week, which committed £8.6 billion (about $11.4 billion) to the program over four years — a signal of long-term funding that industry executives said gives the effort planning certainty through the decade.

The contract also lands at a moment when GCAP stands as Europe's only active sixth-generation fighter development, after the rival Franco-German-Spanish Future Combat Air System (FCAS) effort collapsed in June 2026, according to Breaking Defense.

The detailed design and development phase now underway is intended to mature the fighter's configuration ahead of prototype construction. The partners have consistently maintained 2035 as the in-service target, an ambitious timeline by the standards of recent combat aircraft programs; further production and integration contracts are expected as the design is frozen over the coming 18 months.
