Britain is quietly updating its defense playbook as fears grow that it may be unprepared for a direct Russian attack, with new war-readiness plans reportedly being drawn up behind closed doors.
UK-Russia tensions have been heating up, with Kremlin mouthpieces ramping up talk of invasions and even nuclear strikes.
Back in January, during an appearance on channel Russia-1 top Russian propagandist Vladimir Solovyov warned of using Russia’s Poseidon nuclear drone to flood Britain, which he calls the Kremlin’s top enemy due to its strong Ukraine support.
The UK ranks among Europe’s biggest backers of Ukraine, pledging around US$3.6 billion a year in aid. PM Keir Starmer confirmed the support during his first visit to Kyiv in January, where he met with President Volodymyr Zelensky.
Rishi Sunak, Starmer’s predecessor, pledged ongoing support for Kyiv, committing to stand by Ukraine “for as long as it takes.”
Since the beginning of the Russo-Ukrainian war in 2022, Kremlin propagandists have frequently warned of a potential world war, threatening strikes on NATO territory in response to aid and weapons sent to Kyiv by the Biden administration and other alliance members.
But in March 2024, Russian President Vladimir Putin officially dismissed claims that he planned to attack a NATO member, calling the accusations "sheer nonsense."
Back in January, in his Inauguration Day message to President Trump, Putin said Russia welcomed Trump’s pledge to prevent a third world war, adding his congratulations on Trump’s return to office.
Meanwhile, Kremlin mouthpiece Solovyov mocked Britain’s defense planning, telling viewers across Russia’s 11 time zones that “the main goal for Britain and Europe is to defeat Russia.”
Taunting Prime Minister Starmer, Solovyov doubled down on threats, saying, “Now we're all gonna get together in a coalition of the willing,” while repeating ominous warnings against British and European troops.
In response, British military leaders warn that years of underfunding have left the country vulnerable. Now, a decades-old war contingency plan is reportedly being refreshed to prepare the UK for possible conflict.
The classified plan outlines how the UK government would respond in wartime—from moving the Royal Family and key politicians to bunkers, to keeping public broadcasts up and running during a crisis.
There are growing fears that the UK is vulnerable to Russia, especially given that Putin’s forces reportedly have a much larger arsenal of weapons at the ready.
The report also warns that Britain may be ill-prepared to defend key infrastructure like gas supplies, undersea cables, and nuclear plants in the event of an attack.
The revised homeland defense plan is expected to outline how the UK would respond if a foreign power launched a direct strike on British soil.
The updated plan will now factor in potential missile and nuclear strikes, reflecting a vastly changed threat landscape since it was last revised in 2005.
Created by the Cabinet Office’s Resilience Directorate, the plan will guide the Prime Minister and Cabinet on managing wartime operations, including when to seek shelter in the Downing Street bunker or relocate outside London.
The plan is expected to review strategies for critical infrastructures like rail, road networks, courts, postal services, and phone lines. However, it’s unlikely the document will be made public for decades, if ever.
A risk assessment released in January warned that a successful attack could lead to civilian and emergency service casualties, along with severe economic damage and disruptions to vital services.
In April, officials simulated the first night of Russia's bombardment of Ukraine to test the UK's air defenses.
The wargame tested the UK's response to multiple types of munitions attacking from various directions. Air Commodore Blythe Crawford, former head of the RAF Air and Space Warfare Centre, said the outcome was "not a pretty picture."
The wargame revealed vulnerabilities, such as a shortage of airfields and insufficient hardened shelters, leaving bases and fighter jets exposed.
Defense officials are urging Britain to create its own version of Israel's highly regarded Iron Dome system to defend against missile attacks.
In October 2024, MI5 chief Ken McCallum warned that the UK’s support for Ukraine makes it a prominent target in Putin’s eyes, with continued acts of aggression likely on British soil.
Over the past year, McCallum revealed that investigations into state-sponsored threats, including plots by hostile nations, had risen by 48%.
McCallum highlighted the diverse threats MI5 is tackling, including terrorism, state-backed sabotage, and assassination attempts, all set against the ongoing war in Europe.
Amid rising fears and tensions, a government spokesperson assured that the UK has comprehensive plans, developed and tested over many years, to handle a variety of potential emergencies.
