ROME— The United Kingdom (UK), Italy, and Japan have taken a key step to stabilize the Global Combat Air Programme (GCAP), signing a short-term funding contract to maintain development momentum.
The agreement ensures continued progress on the sixth-generation fighter project while the United Kingdom finalises its broader defence financing strategy.
Leonardo (LON), BAE Systems (BAE), and Japan Aircraft Industrial Enhancement Co., Ltd. continue to lead industrial development through their joint venture, Edgewing. The programme aims to deliver a next-generation combat aircraft by 2035.
The latest agreement reflects coordinated trilateral efforts to avoid disruption caused by budget uncertainty.

UK Unlocks Funding for GCAP Fighter
The GCAP joint programme office announced a £686 million ($906 million) development contract with Edgewing, designed to sustain engineering and design activities for the next three months.
The funding acts as a stopgap measure while the UK prepares its Defence Investment Plan.
Officials from the trilateral agency stated that the contract strengthens cooperation and accelerates delivery across partner nations.
The funding ensures that engineering teams remain active and that key design milestones continue without interruption during the transitional period.
The agreement marks the first unified contract signed directly between the three governments and Edgewing, replacing earlier fragmented national funding arrangements.

Funding Pressure
The UK continues to face pressure to finalise its Defence Investment Plan, which has been delayed amid fiscal constraints and a reported £28 billion gap in defence spending projections.
The absence of a completed plan created uncertainty around long-term commitments to GCAP and other defence programmes.
Despite these challenges, the UK government has recently moved to support aerospace manufacturing continuity. A separate £1 billion contract awarded to Leonardo for AW149 helicopter production highlighted efforts to protect domestic industrial capability while broader funding decisions remain pending.
Programme stakeholders have expressed concern that funding delays could affect delivery timelines. Japan has previously indicated that it wants the GCAP fighter to remain on track for its 2035 target.

Edgewing’s role expands
Edgewing, the industrial lead for GCAP, now plays a central role in managing technical development across the three nations.
According to Defense News, the company confirmed that the new contract enables uninterrupted engineering work and supports planned programme milestones.
The joint venture also noted that GCAP represents a unique global collaboration in combat aircraft development, with full technical responsibility placed under a single international prime contractor structure.
This model integrates design and development efforts across all partner nations for the first time in such a programme.
Masami Oka, GCAP Agency Chief Executive, stated that the contract marks a shift from separate national contracts to a unified international structure. This change aims to improve coordination and streamline programme execution across all stakeholders.
