The UK Conservative Party has announced a proposal to invest £10 billion into a new nationwide missile and drone defence system, dubbed "Britannia Shield," if they return to government. Described as a "British 'Iron Dome'" in reference to Israel's defensive network, the system is designed to protect the UK's critical national infrastructure, military bases, and sovereign territories from advanced aerial threats.
The proposed shield would consist of three main components: advanced radar networks, upgraded command and control systems to rapidly coordinate defensive actions, and new interceptor missiles alongside counter-drone capabilities. The Tories stated that this proposal would significantly strengthen the UK's air defences at a time when Nato allies are warning of repeated Russian drone incursions.
Speaking at the Conservative Party conference in Birmingham, Shadow Defence Secretary James Cartlidge will call the initiative "the most significant upgrade to UK air defence for generations" and "one of Britain's most significant military programmes since the cold war." Cartlidge is expected to argue that the £10 billion program is "totally necessary because of the threats we face." The party also highlighted a House of Commons defence committee report from last November, which warned that the UK lags behind its European allies in planning to defend its mainland and overseas territories from military attacks.
According to the Conservatives, the multi-billion-pound project would be financed through their existing commitment to allocate 3% of the UK's GDP to defence by 2030. This spending target would be met through welfare reforms and the reprioritisation of existing government expenditure.
The proposal drew sharp criticism from Defence Secretary Wes Streeting, who dismissed the pledge and pointed to the Conservatives' "abysmal record" during their 14 years in power. Streeting remarked, "They owe Britain an apology, not another lecture." He accused the Tories of reducing the British Army to its smallest size since the Napoleonic era and leaving a £17 billion deficit in the military equipment budget. Streeting also cited former Tory Defence Secretary Ben Wallace, who previously acknowledged that the UK's armed forces had been "hollowed out and underfunded."
The proposed "Britannia Shield" draws on a three-tiered architecture similar to the British Army's active Sky Sabre air defence system. Sky Sabre, which is capable of intercepting missiles and aircraft and integrating with broader defensive networks, was recently deployed to the Middle East to counter Iranian attacks. It was also previously stationed in Poland to support Ukraine, and was showcased in 2022 at the Royal Artillery's change of colours parade at Baker Barracks on Thorney Island.
Under the current Labour government, the Defence Investment Plan has allocated more than £350 million to double the British Army's inventory of Sky Sabre systems, integrating ground-based air defence with air and maritime capabilities. Meanwhile, Prime Minister Andy Burnham has faced ongoing pressure to outline how the UK will achieve Nato's target of spending 3.5% of GDP on defence by 2035, up from an estimated 2.6% this year.
