Conservatives propose £10bn missile shield as rivals challenge funding
The opposition’s Britannia Shield plan covers radar, interceptors and counter-drone systems. It is a pledge for a future government, not an operational defence network.
The Conservatives have proposed spending up to £10bn over a decade on an integrated missile and drone defence network. Details released ahead of James Cartlidge’s Tuesday conference speech describe new radar, command systems and interceptor missiles, alongside counter-drone capabilities and larger missile stocks.
An initial capability, then expansion
The party says a first deployable capability would be delivered during its first term in government, with further expansion over time. The pledge does not establish that a nationwide shield exists, that equipment has been ordered or that all locations would receive equal protection.
The funding dispute
Conservatives link the proposal to their commitment to defence spending of 3% of GDP by 2030, funded through welfare reform and changes to existing spending. Liberal Democrat defence spokesperson James MacCleary disputes whether £10bn would cover a UK-wide system and criticises the proposed welfare cuts.
Labour’s response
Labour challenges the Conservatives’ record and points to its own planned investment in air defence and commitment to 3.5% of GDP on defence by 2035. The competing announcements concern future spending and capabilities; delivery and coverage remain the practical tests.
