The chief executive of Rolls-Royce Holdings has said he would be “definitely open” to Germany joining the UK’s next-generation fighter jet project, known as the Global Combat Air Programme (GCAP), arguing that additional partners could expand production and future sales opportunities.

About the Programme

The advanced aircraft is being developed as a successor to the Eurofighter Typhoon and is currently a joint initiative between the United Kingdom, Italy, and Japan. Rolls-Royce is responsible for developing the engine for the new combat aircraft.

The programme, also referred to as Tempest, aims to deliver a sixth-generation fighter intended to enter service by 2035.

Potential Expansion and Geopolitical Context

Speculation about Germany joining GCAP has increased following tensions within the Future Combat Air System (FCAS), a separate joint effort between France and Germany. Reports indicate disagreements between major industrial partners, including Dassault Aviation and Airbus.

German officials have previously signalled concerns about the direction of FCAS, contributing to broader discussions about alternative collaboration options.

Rolls-Royce’s chief executive, Tufan Erginbilgic, said expanding GCAP membership could increase procurement commitments, noting that participation often leads to purchasing alignment among partner nations. However, he emphasized that decisions on new partners ultimately rest with governments rather than companies.

The UK government has indicated it remains open to additional partners joining the programme while maintaining delivery timelines.

Defence Investment and Economic Impact

European governments have been increasing defence spending amid heightened security concerns. Industry leaders argue that investment in military technology can also generate broader economic and technological benefits, including spillover into civil aerospace and export markets.

Erginbilgic noted that defence capabilities contribute to the UK’s ability to export military aircraft and support domestic industrial growth, highlighting the interconnected nature of defence and commercial aerospace sectors.

Company Performance and Market Reaction

Rolls-Royce recently reported a 40% increase in annual profits, reflecting progress in its turnaround strategy and strong demand in power systems, particularly from data centre infrastructure.

Market movements followed geopolitical developments, with defence stocks experiencing volatility. Shares in some defence companies rose, while Rolls-Royce shares edged lower amid concerns about potential impacts on global travel demand.

Government Position

A UK government spokesperson reiterated that, alongside Japan and Italy, the UK remains open to other partners joining GCAP, while keeping the programme on schedule and maintaining delivery commitments.

Outlook

The future composition of the fighter programme will depend on diplomatic alignment, technical integration, and procurement agreements among participating nations. Analysts suggest that while expansion could enhance industrial participation, it may also require careful coordination to avoid delays in the development timeline.
