The Ministry of Defence has announced a £4.6 billion contract under the Global Combat Air Programme, the trilateral effort with Italy and Japan to develop a sixth-generation combat aircraft for service from 2035. Alongside the contract, the Defence Investment Plan states that the UK will commit £8.6 billion to GCAP over the next four years. Defence Minister Luke Pollard described the agreement as a major step towards delivery and linked it to RAF capability, allied cooperation and skilled employment in the UK.
According to the Ministry of Defence, the £4.6 billion award is jointly funded by the three partner nations, has been let through the GCAP Agency and has gone to industry joint venture Edgewing. The work covers the next stage of aircraft design, including the definition of key requirements and the testing needed to move the programme forward. In procurement terms, that marks a shift from political commitment and early concept work towards a more formal design phase. It is the point at which budget announcements begin to connect to programme structure, delivery milestones and shared oversight between the three governments.
The Ministry of Defence says the future aircraft will operate alongside Typhoon, F-35 and autonomous systems, rather than replacing the current combat air mix on its own. The ministry also describes the platform as intended to become the most advanced fighter flown by the RAF, built through digital engineering, artificial intelligence and advanced manufacturing methods. That presentation matters because GCAP is being advanced on two tracks. It is a military capability programme for the RAF, but it is also being used to accelerate new production methods in defence, including robotics, augmented reality and additive manufacturing, which the government says are already shaping design and testing work.
On the industrial side, the Ministry of Defence says the UK's future combat air system already supports 4,500 jobs and a supply chain of about 600 organisations. The official case for spending therefore goes beyond operational need and extends to retaining sovereign design, engineering and manufacturing capacity in combat air. That framing matches the ministry's emphasis on the sovereign industrial base, skilled manufacturing jobs and national security. In practice, a programme of this size spreads work across software, sensors, propulsion, materials, testing and specialist manufacturing, not only across the prime contractors.
The Defence Investment Plan places the GCAP contract inside a wider RAF equipment package. Alongside the £8.6 billion earmarked for GCAP over four years, the plan confirms more than £1.1 billion to upgrade and sustain Typhoon into the 2040s, £2.2 billion for further F-35 purchases and £300 million to begin developing a new UK autonomous combat aircraft. Read together, those figures set out a layered combat air model more clearly than the contract announcement on its own. The government is planning around upgraded Typhoons, a larger F-35 fleet, autonomous systems and a sixth-generation aircraft entering service from 2035.
The wider policy message is about allied procurement as much as hardware. GCAP binds the UK, Italy and Japan into a shared long-term programme, giving each partner access to a broader industrial and research base while also requiring continuing agreement on cost, requirements and schedule. For the UK, the announcement confirms that future combat air remains a priority line in defence spending and industrial policy. The immediate contract milestone is now complete; the next stages are disciplined programme management, sustained funding and progress against the 2035 in-service target set out by the Ministry of Defence.
