UK Tories pledge £10bn 'Britannia Shield' air defence system

The UK Conservative Party has announced a £10bn 'Britannia Shield' air defence programme, framed as a response to NATO warnings about Russian drone incursions. The pledge is a campaign proposal, not a committed procurement, and its feasibility and timeline remain uncertain. It signals a shift in UK defence policy discourse toward homeland air defence, potentially influencing NATO posture and defence spending debates.
