UK and France Strengthen Nuclear Defence Cooperation with Inaugural Joint Exercise

For the first time, RAF Typhoon fighters have participated in a French nuclear air exercise, joining forces with French Rafale jets in a demonstration of allied strength and cooperation. This significant event, known as Exercise “Rummy,” represents a considerable advancement in defence collaboration between the UK and France, as outlined in the Northwood Declaration. Such partnerships are essential for safeguarding the UK and countering threats in an increasingly complex global security landscape.

Strengthening UK Defence Capabilities

The UK’s defence posture is being bolstered as RAF Typhoon fighters engage alongside French Rafale aircraft in a nuclear exercise on French soil. Exercise “Rummy” saw British and French forces operating in unison over the Mediterranean, showcasing their readiness and capability to deter potential threats and ensure the safety of the UK.

Launching from Saint-Dizier Air Base in France, the French Rafale conducted a simulated nuclear strike mission, with RAF Typhoons providing crucial escort support. The exercise adhered to stringent safety and security protocols, and it was important to note that no nuclear weapons were involved. Instead, the focus was on enhancing the interoperability of both nations’ forces, ensuring that should the UK encounter a significant threat, its military could respond swiftly and effectively alongside its closest European ally.

Commitment to Collective Security

This exercise underscores the UK’s dedication to confronting any threats in a united front, reinforcing deterrence and ensuring peace and security alongside European allies. As prominent NATO partners and nuclear powers, the UK and France play a vital role in maintaining the security of the Euro-Atlantic region.

Exercise “Rummy” aligns with the UK’s broader strategic objectives, including a £63 billion investment over the next four years aimed at enhancing its nuclear deterrent. This funding will support critical projects such as the Dreadnought and SSN-AUKUS submarines, the development of a new warhead, and other essential nuclear initiatives. The UK is also set to acquire 12 F-35A aircraft and participate in NATO’s nuclear mission, contributing to a more integrated European defence framework.

Statements from Defence Leadership

Defence Secretary Wes Streeting remarked on the significance of the exercise, stating, “This exercise marks a new chapter in the defence nuclear relationship between the United Kingdom and France.” He emphasised the shared responsibility of Europe’s nuclear powers to enhance security and stability within the Euro-Atlantic area, pointing out that this exercise exemplifies the strength of their partnership, the reliability of their deterrents, and their resolve to stand united against emerging threats.

Catherine Vautrin, Minister of the Armed Forces and Veterans, added, “Having independent nuclear forces does not exclude coordination. Our nuclear cooperation with the United Kingdom keeps deepening.” She highlighted that the participation of UK Typhoons in a French nuclear exercise illustrates the potential for coordinated efforts to enhance the overall security of the Alliance and contribute to peace and stability in the Euro-Atlantic region.

A Milestone in Bilateral Nuclear Defence

Exercise “Rummy” marks a pivotal moment in the UK-France nuclear partnership and the cooperative programme established under the Northwood Declaration. This exercise not only demonstrates the commitment of both nations to jointly deter common threats but also highlights the depth of their bilateral nuclear defence relationship. The successful collaboration exemplifies that British and French forces are well-prepared to operate together, thereby safeguarding shared interests and enhancing collective security amid rising global instability.

The UK and France remain steadfast defence allies, bolstered by the refreshed Lancaster House Agreement, which aims to expand their joint deployable forces, enhance nuclear cooperation, and develop the next generation of advanced weaponry.

Operation Rummy took place from 20-21 October 2026, reinforcing the continued importance of sovereign and independent nuclear forces and national decision-making for both the UK and France.
