Senior officials and military representatives from the United Kingdom and France convened in London to enhance nuclear collaboration under the Northwood Declaration. The meeting of the Nuclear Steering Group (NSG), co-chaired by the UK Cabinet Office and the French Presidency, focused on the substantial strides made in fostering coordination between the independent nuclear deterrents of both nations.
The NSG underscored the significance of adversaries understanding that any threat to the vital interests of either country would be met with the unified strength of both military forces. The group praised the recent involvement of the UK in France’s airborne nuclear exercise, known as Operation Rummy, which exemplified the growing operational alignment between the two countries.
Discussing the Forward Deterrence Initiative
In addition, the discussions included France’s “Forward Deterrence” initiative, with the NSG recognising its considerable contribution to European security and its role in complicating the strategic calculations of potential adversaries beyond NATO. This initiative is seen as a vital component of the broader deterrent framework within the Euro-Atlantic region.
Building upon the achievements of the 2010 Teutates Treaty and the establishment of the joint UK-France testing facility, EPURE, the NSG reached an agreement to broaden cooperation across various technical capabilities. This includes initiating reciprocal access to sovereign testing facilities in both countries, thereby enhancing their collaborative capabilities in nuclear deterrence.
Commitment to Non-Proliferation Efforts
The NSG reaffirmed the commitment of the UK and France to uphold and strengthen the global non-proliferation framework. They emphasised the importance of ongoing meaningful engagement with other Nuclear Weapon States, particularly in connection with the Non-Proliferation Treaty review process and the P5 Process. It is noteworthy that France is set to assume the leadership role from the UK in this process starting September 2026.
