Berlin, Germany – October 8, 2026 – In a move that has sent ripples through the international defense and political landscape, British Prime Minister Andy Burnham, during his inaugural state visit to Berlin, extended a surprising and significant offer to Germany: joint development of a next-generation fighter jet. This proposal, revealed during a high-stakes meeting with German Chancellor Friedrich Merz at the Chancellery, underscores a potent desire from the new British leadership to forge a deeper, more integrated strategic relationship with continental Europe, particularly with Germany, in the wake of Brexit.
The offer centers on Germany’s potential participation in the Global Combat Air Programme (GCAP), a multinational initiative spearheaded by the United Kingdom, Italy, and Japan. GCAP aims to develop a cutting-edge stealth fighter jet, a project that represents a crucial step in modernizing air power for the participating nations. This overture comes at a critical juncture for Germany, which recently saw its own ambitious Franco-German fighter jet project, the Future Combat Air System (FCAS), falter after protracted disputes. Burnham’s proposal presents a compelling alternative, positioning Germany at the forefront of a significant European defense undertaking.
A Bold Defense Overture: Beyond Bilateralism
Prime Minister Burnham’s willingness to extend an invitation to Germany for the GCAP program signifies a strategic shift. GCAP, a collaborative effort already involving three major global players, represents a significant technological and financial undertaking. Germany’s potential inclusion would not only bolster the program’s capabilities but also signal a renewed commitment to European defense integration, even outside the formal structures of the European Union.
"We are open to Germany participating in this project," Prime Minister Burnham stated at a joint press conference following his discussions with Chancellor Merz. "This is something we are eager to advance in the coming period." The implication is clear: Britain, despite its departure from the EU, views Germany not merely as a bilateral partner, but as a crucial player in shaping the future of European security architecture.
The Kensington Treaty: A Framework for Renewed Alliance
The defense cooperation offer is intrinsically linked to the recently ratified Kensington Treaty, a comprehensive friendship agreement signed in July 2025 during Chancellor Merz’s reciprocal visit to London. This landmark accord, meticulously negotiated, goes beyond mere defense, encompassing a wide array of collaborative initiatives spanning foreign policy, security, and economic engagement. The treaty’s ambitious scope aims to create a robust framework for continued, and in some areas, intensified cooperation between the two nations, even in the post-Brexit era.
Among the treaty’s provisions are measures designed to foster closer ties in areas such as combating hybrid threats, enhancing intelligence sharing, and streamlining diplomatic efforts on the global stage. Furthermore, the Kensington Treaty includes provisions for enhanced people-to-people connections, such as planned visa facilitation for school groups undertaking educational trips, a seemingly minor detail that speaks to a broader ambition to nurture future generations of cross-cultural understanding and collaboration.
Chancellor Merz hailed the treaty and the ensuing visit as "a historic day," emphasizing its potential to unlock "new opportunities for cooperation" between the United Kingdom and Germany. His remarks, particularly the poignant observation that "after Great Britain unfortunately left the European Union, we are now at least bilaterally making a treaty," highlight the unique diplomatic challenge and opportunity presented by this new relationship. It acknowledges the reality of Brexit while simultaneously forging a strong, independent partnership.
Prime Minister Burnham echoed this sentiment, framing the treaty as an essential response to the current global climate. "In challenging times – and these are challenging times – we need cooperation of the highest quality with our closest partners, and Germany is indeed one of our closest partners," he asserted. He further elaborated that the Kensington Treaty is poised to "improve security in Europe, grow the economies of both countries, and raise the living standards of their populations."
Addressing Hybrid Threats and the Post-Brexit Landscape
Beyond the headline-grabbing fighter jet proposal, the Kensington Treaty outlines concrete steps for collaboration on pressing security challenges. Prime Minister Burnham specifically highlighted the joint approach to countering hybrid threats. Both Germany and the United Kingdom, he noted, are "confronted with these challenges, and it makes sense to face these threats together and to support each other in their defense." This shared vulnerability to sophisticated, often state-sponsored, interference and disruption underscores the practical necessity of their enhanced security cooperation.

Burnham’s visit to Berlin is particularly noteworthy as it marks his first official trip to an EU member state since assuming the premiership. This deliberate choice signals a clear intention to re-engage with European partners, even as Britain navigates its post-Brexit reality. His prior visits to Ukraine and the United States already indicated a focus on key strategic alliances.
The British Prime Minister has, in recent weeks, also openly discussed the possibility of the UK’s eventual return to the European Union. This nuanced stance, acknowledging the potential benefits of EU membership while simultaneously pursuing robust bilateral agreements, suggests a pragmatic and adaptable approach to Britain’s international relations. His engagement with Germany, a leading power within the EU, is a critical component of this broader strategy.

Supporting Data and Context:
The decision to offer Germany participation in GCAP is underpinned by several key factors:
- The Failure of FCAS: The collapse of the Franco-German Future Combat Air System (FCAS) project in the summer of 2026 left Germany without a clear path forward for its next-generation air combat capabilities. This void created an opportune moment for Britain to present GCAP as a viable and advanced alternative. FCAS was plagued by disagreements over industrial leadership, technological specifications, and strategic direction, highlighting the complexities of large-scale multilateral defense projects.
- Technological Advancement of GCAP: The GCAP program, while still in its developmental stages, is widely recognized for its ambitious technological goals, including advanced stealth capabilities, integrated sensor fusion, and network-centric warfare integration. These characteristics align with the future operational requirements of modern air forces.
- Economic Synergies: Germany’s inclusion in GCAP would bring significant industrial and technological expertise, potentially enhancing the program’s overall efficiency and innovation. From an economic perspective, such a joint venture could lead to substantial investment, job creation, and the development of cutting-edge aerospace technologies in both nations.
- Strategic Imperatives: In an increasingly volatile global security environment, characterized by rising geopolitical tensions and the proliferation of advanced military technologies, a robust and technologically superior air defense capability is paramount. The GCAP initiative, with German participation, would represent a significant enhancement of collective European and transatlantic security.
