The United Kingdom is in the process of updating a significant national strategy aimed at readying the entire country — from its armed forces and law enforcement to healthcare and industrial sectors — for a potential transition to wartime readiness, as disclosed by the military’s top official.
Air Chief Marshal Sir Richard Knighton announced plans for a revised version of the “Government War Book,” stressing the need for a new resilience approach inspired by Cold War strategies but tailored to modern society and current infrastructure.
During the London Defence Conference, Knighton also noted the impact of Britain’s warning to potentially intercept vessels associated with Russia’s “shadow fleet.” Although no ships have been boarded yet, the threat has compelled Moscow to provide escorts for these tankers or reroute them away from UK waters, with some still observed near the coast. Knighton affirmed readiness for boarding operations, stating, “We are prepared.”
One of the military’s significant challenges is revitalizing the Royal Navy, British Army, and Royal Air Force to a state of wartime readiness after years of underinvestment following the Cold War’s conclusion. Prime Minister Sir Keir Starmer and Defence Secretary John Healey have committed to increasing defense spending to 3.5% of GDP from slightly over 2%, but not until 2035.
The anticipated 10-year Defence Investment Plan, outlining future weaponry and capabilities, is yet to be released, leaving the defense industry in uncertainty. Knighton suggested that delays may be due to the Ministry of Defence’s push for quicker access to additional Treasury funds, expressing a preference for a well-funded and achievable plan, even if finalization takes longer.
At the core of Knighton’s discussion was the initiative led by the Cabinet Office to revive the government’s war book concept, first established during World War I. These plans historically ensured the UK’s preparedness by detailing mobilization strategies for the military, civilians, and industry during crises, including measures like school closures, hospital coordination, food rationing, and safeguarding national assets.
Although the system was phased out post-Cold War due to maintenance costs, Knighton indicated its modernized revival. He emphasized NATO’s approach to transitioning to conflict, which involves both military and civilian aspects, stressing the need to fortify critical infrastructure — such as energy, water, and transportation systems — against natural disasters and potential threats.
Knighton highlighted the necessity for future infrastructure advancements to consider unconventional threats, necessitating altered priorities and long-term governmental planning. He warned that the stability enjoyed by Britain in recent decades is under pressure, underscoring the importance of raising public awareness about potential threats and citizen involvement in strengthening national resilience and supporting the armed forces.
