The historic £4.6 billion deal signed between the UK, Japan, and Italy marks a pivotal moment in the development of next-generation fighter jets, driving forward the ambitious Global Combat Air Programme (GCAP). This landmark agreement will catalyse the design phase of the sixth-generation aircraft, set to enter service by 2035, with a focus on cutting-edge technologies such as digital engineering, advanced propulsion systems, and sophisticated sensor arrays.
As part of the £8.6 billion commitment outlined in the Defence Investment Plan (DIP), this substantial investment is intended to not only bolster British jobs but also stimulate innovation within the defence sector, ultimately enhancing national security capabilities. Minister for Defence Readiness and Industry Luke Pollard MP highlighted that the programme will provide RAF pilots with a "cutting-edge stealth fighter jet," solidifying partnerships with international allies and supporting thousands of highly skilled jobs across the UK.
The GCAP aircraft is designed to seamlessly integrate with the Royal Air Force's existing Typhoon and F-35 fleets, as well as emerging autonomous systems. It will incorporate complex digital engineering, artificial intelligence (AI), and other groundbreaking technologies, making it the most advanced fighter jet flown by the RAF. Already, the programme has driven tangible advancements in UK digital engineering and advanced manufacturing, including the use of AI, robotics, augmented reality, and additive manufacturing to accelerate design, testing, and production processes.
Beyond its military implications, the GCAP is projected to deliver significant long-term economic benefits to the UK. As a crucial part of the country's broader future combat air system, it currently supports approximately 4,500 jobs nationwide. With a supply chain involving around 600 organisations, the initiative aims to strengthen the UK's sovereign industrial base and secure skilled manufacturing employment.
The Defence Investment Plan also detailed further commitments, including over £1.1 billion for upgrading and sustaining the RAF’s Typhoon force into the 2040s, £2.2 billion for expanding the UK’s F-35 stealth fighter jet fleet, and £300 million to initiate the development of a new UK autonomous combat aircraft.
