The Consortium for the GCAP Power and Propulsion System is progressing toward ground-testing the engine demonstrator.

Avio Aero (Italy), IHI Corporation (Japan) and Rolls-Royce have moved a step closer to ground-testing the engine demonstrator for the Global Combat Air Programme (GCAP), following a series of consortium design reviews.

United by a shared vision, the consortium is driving the generational change in power and propulsion required to deliver the world’s most advanced next-generation combat aircraft. By strengthening their collaborative approach and reaching key technological milestones, the partners are advancing the capabilities that guarantee the future security of our nations.

Momentum with the Power and Propulsion System

The trilateral partnership is moving from strength to strength through enhanced consortium collaboration, uniting the partners into one truly collaborative international team.

The past year has seen the opening of a dedicated Collaboration Hub in Reading, UK, creating a central location for partner co-location and closer collaboration with the GCAP Agency and Edgewing. More than a physical workspace, it represents a tangible demonstration of the long-term commitment, trust and collaboration that underpins the international partnership.

Technology development also continues to advance. The consortium reviews have moved the programme towards final approval of the all-new centre line engine demonstrator design, with continued progression of component manufacturing. Over 100 subscale component tests have been completed so far, bringing the consortium closer towards ground-testing the trilaterally-developed engine demonstrator, which will gather critical data to understand and shape the design and development of the full power and propulsion system for GCAP.

The engine demonstrator plays a crucial role in de-risking the programme, demonstrating maturity of innovative technology and integrated architecture, whilst being a mechanism to test and refine processes, tools and ways of working—contributing towards shortening the design and development cycle for GCAP.

Europe’s security landscape is changing rapidly

As defence budgets rise and EU programmes expand, civil technology providers are becoming vital contributors to Europe’s strategic autonomy. The event will act as a neutral platform for dialogue between technology suppliers, integrators, and decision-makers shaping the next generation of European defence capabilities and aims to open doors between civil industry and defence procurement, providing practical insights.

Edoardo Curti, General Manager of the Defence Business Unit, Avio Aero, said: "The progresses achieved by the teams across our three companies in developing the engine demonstrator represent a significant milestone in our shared commitment to delivering next-generation capability and meeting our customers’ evolving requirements. We are proud to continue strengthening our collaboration with Rolls-Royce and IHI, laying the groundwork for a strong, long-term partnership under GCAP.”

Noriyuki Nakamura, Senior Technical Advisor, Aero Engine, Space & Defence Business Area, IHI Corporation, said: "Within this international framework, IHI is integrating Japan’s cutting‑edge engine technologies with the outstanding expertise of Avio Aero and Rolls‑Royce to shape a new generation of power and propulsion—the ‘heart’ of tomorrow’s combat aircraft. By building a network of trust and co‑creation that transcends national and corporate boundaries, this multi‑decade endeavour will open new horizons for the defence aerospace engine industry and nurture future business, talent and international partnerships.”

Phil Townley, Director of Future Programmes, Defence, Rolls-Royce, said: "We aren’t just generating thrust; we are creating a flying power station capable of managing the unprecedented electrical and thermal loads required by next-generation sensors and weapon systems.“Working as one trilateral team with Avio Aero and IHI, we are breaking down geographical and industrial boundaries to deliver this capability at pace.”

Economic engine: strengthening skills and industry

The consortium is driving economic prosperity and a highly-skilled talent pipeline across all three nations. The programme currently sustains more than 9,000 highly-skilled aerospace roles worldwide and continues to invest in the development of future talent across the partner nations.
