Britain and France have agreed to deepen cooperation between their independent nuclear deterrents, including expanded technical collaboration and reciprocal access to national testing facilities.
Senior officials and military representatives met in London on 10th November under the UK–France Nuclear Steering Group, established through the Northwood Declaration.
The meeting reviewed progress towards closer coordination between Europe's two nuclear-armed powers.
Expanding Technical Cooperation
Both governments agreed to expand cooperation on nuclear-related technical capabilities and begin reciprocal use of sovereign testing facilities.
The arrangements build on the 2010 Teutates Treaty, which established cooperation on nuclear weapons technology and led to the development of the joint EPURE testing facility in France.
The latest agreement extends this existing partnership while preserving independent national control over each country's nuclear forces.
Recent Joint Military Exercise
The meeting followed Britain's first participation in a French airborne nuclear exercise.
During Operation Rummy on 20th–21st October, RAF Typhoon fighters escorted French Rafale aircraft conducting a simulated nuclear strike mission over the Mediterranean.
No nuclear weapons were involved.
The exercise demonstrated closer operational coordination between British and French forces under the Northwood Declaration.
Implications for European Security
Officials also discussed France's Forward Deterrence initiative, which seeks to strengthen the contribution of French nuclear capabilities to European security.
Both governments emphasised that closer coordination could complicate the calculations of potential adversaries threatening either country's vital interests.
Britain and France will continue operating independent nuclear deterrents, with national authorities retaining responsibility for decisions concerning their use.
The two countries also reaffirmed their commitment to international nuclear non-proliferation arrangements.
