BRUSSELS, BELGIUM / EuroWire / – NATO defence ministers approved an update to the alliance’s nuclear capabilities on June 18, 2026, during a ministerial meeting of the Nuclear Planning Group in Brussels. The decision covers nuclear modernisation, stronger planning capacity and further adaptation of NATO’s deterrence posture. The alliance said the step aims to keep its nuclear deterrent safe, secure, effective and credible.
The Nuclear Planning Group serves as NATO’s senior body for nuclear deterrence matters. It reviews nuclear policy, doctrine, planning, force posture, capabilities and exercises. All NATO members take part except France, which maintains an independent nuclear policy. The Brussels session came during a wider defence ministers’ meeting chaired by NATO Secretary General Mark Rutte.
NATO said strategic nuclear forces remain the supreme guarantee of allied security. The alliance also said its nuclear posture helps preserve peace, prevent coercion and deter aggression. Ministers reaffirmed that nuclear weapons form part of NATO’s wider deterrence and defence framework, alongside conventional forces, missile defence, space capabilities and cyber capabilities.
Nuclear Planning Group backs modernisation
The decision did not include public details on specific weapons, basing changes, deployment numbers or procurement costs. NATO described the update in broad policy terms. It said ministers agreed to modernise nuclear capabilities, strengthen nuclear planning capacity and adapt the deterrence mission to allied security interests.
Rutte said ministers would continue to improve nuclear planning and ensure the deterrent remains fit for purpose. His comments followed the Nuclear Planning Group statement and linked the decision to the alliance’s wider defence readiness agenda. The meeting also took place as members prepare for the NATO summit in Ankara.
Alliance keeps arms control policy
NATO says it remains committed to arms control, disarmament and non-proliferation. It also says it will remain a nuclear alliance as long as nuclear weapons exist. The alliance’s nuclear arrangements rely on national capabilities, allied planning and forces assigned to the deterrence mission under long-standing consultation and command structures.
The nuclear update adds to a series of 2026 defence discussions focused on readiness, spending, industry output and support for Ukraine. NATO has kept nuclear policy under regular review through the Nuclear Planning Group since 1966. The Brussels decision keeps that process active while leaving operational details undisclosed to the public.
