UNIPA News 05 June(London)-The United Kingdom faces its most serious security environment since the Cold War and must prepare for the possibility of prolonged, large-scale conflict, according to Chief of the Defence Staff Sir Richard Knighton.
Speaking on the BBC’s Today programme on Friday, Sir Richard said the current threat landscape is the most dangerous he has experienced during his military career. He warned that risks facing the UK have reached levels not seen since the Cold War, citing increased military activity by Russia and evolving forms of modern warfare.
Sir Richard stated that the first five months of this year had witnessed as many incursions by Russian strategic aircraft near UK airspace as occurred during the entirety of 2025. He said Russia was testing Britain’s defenses through conventional military activities as well as cyber operations, sabotage attempts and other forms of hostile activity.
The defence chief described last year’s Strategic Defence Review as a “call to arms,” arguing that the UK’s armed forces must move beyond preparations for short, localized conflicts and develop the capacity to sustain operations during extended wars similar to the conflict in Ukraine.
He emphasized the growing importance of drones, autonomous systems and emerging technologies on future battlefields, saying modern military planning must adapt to rapidly changing warfare requirements.
The warning comes ahead of the expected publication of the UK’s Defence Investment Plan, a document expected to outline defence spending priorities for the next decade.
Earlier this year, Sir Richard and Germany’s Chief of Defence, General Carsten Breuer, jointly called for stronger European rearmament efforts in response to what they described as an increasing threat from Russia. In a joint statement, the two military leaders argued that Europe must confront new security realities and undertake a significant strengthening of its defence capabilities.
Their remarks followed discussions at the Munich Security Conference, where political and military leaders examined the future of European security and ongoing developments in the war in Ukraine.
The latest comments underscore growing concern among European defence officials regarding regional security, military preparedness and the long-term implications of Russia’s actions for the continent’s defence posture.
