The Conservative Party said its “Britannia Shield” would have three components – new advanced radar systems, upgraded command and control systems to integrate information from across Britain’s defences and rapidly decide a response, and new interceptor missiles as well as counter-drone capabilities.
The three-tiered design of the proposal is similar to the British Army’s current Sky Sabre, external air defence system.
This system – which can intercept munitions and aircraft as well as integrate with wider air defences – was deployed by the UK to the Middle East earlier this year for defensive action against Iranian attacks.
In his speech at the conference in Birmingham, Cartlidge will say: “With a £10bn budget, this would be one of Britain’s most significant military programmes since the cold war.
“But one that is totally necessary because of the threats we face.”
Streeting said in response: “They [the Conservatives] cut the Army to its smallest size since Napoleon and left a £17 billion hole in the equipment plan.
“Their own defence secretary, Ben Wallace, admitted our Armed Forces had been ‘hollowed out and underfunded’.”
The Conservatives said their plan would be funded within their existing commitment to spend 3% of GDP on defence by 2030, paid for by welfare reform and reprioritisation of existing expenditure.
Prime Minister Andy Burnham has been under pressure to set out how he will reach Nato’s 3.5% of GDP spending target by 2035, up from an estimated 2.6% this year.
The current Labour government’s Defence Investment Plan includes more than £350m to double the number of Sky Sabre systems operated by the British Army, with ground-based air defence sitting alongside air and maritime capabilities.
