The Conservatives have proposed spending £10 billion over ten years on a new UK air defence system if they return to government. Named Britannia Shield, it would bring together radar, command systems, interceptor missiles and equipment to counter drones, according to the party’s announcement reported by ITV News.
The plan is an opposition party pledge. No decision has been made to build the system, and the Conservatives have not published a detailed design showing which sites it would protect or how the proposed budget would be divided between equipment, operations and maintenance.
What would the system do?
The Conservatives say Britannia Shield would help defend Britain, its overseas territories and military bases against missile and drone attacks. Shadow defence secretary James Cartlidge described it as an integrated system with several layers of protection. The party proposes allocating about £1 billion a year for a decade to the project.
The party initially called the proposal, in essence, a British version of Israel’s Iron Dome. Badenoch later said it would not replicate the Israeli system. She told broadcasters that Britain needs a system tailored to the threats it faces. The change in description leaves an important question for voters: what level of protection would £10 billion actually buy?
How would it be funded?
Badenoch says the spending would form part of the Conservatives’ wider pledge to raise defence expenditure to 3% of UK economic output by 2030. The party points to proposed welfare changes and other spending decisions as ways to fund its defence plans. Those changes would themselves require political approval and have not been implemented.
The proposal has drawn criticism from other parties. Labour says it is already investing in air defence and challenged the Conservatives’ defence record. The Liberal Democrats questioned whether £10 billion could provide complete protection across the UK. Neither criticism establishes what the proposed system would cost; that depends on its final scope, which has yet to be set out.
