The government has currently committed about £790m for integrated air and missile defence (IAMD) in the Defence Investment Plan.Cartlidge will say that the British version of the Iron Dome will have new advanced radar systems to detect threats, a new command and control system and a new stockpile of missiles and counter-drone capabilities.That would in practice be a fundamentally different model to the Israeli Iron Dome system, which protects a country a twelfth of the size of Great Britain and is primarily designed to counter short-range threats like rockets and artillery, with other defence systems that counter longer-range missiles.Other European countries, including Germany, Greece, Cyprus and Poland, are investing significantly in air defence systems, though the UK is under limited direct threat from ongoing conflicts, unlike some of those nations.The Conservative leader, Kemi Badenoch, said that Labour were “failing that basic test” of keeping the country safe.
The chancellor, John Healey – who previously quit as Keir Starmer’s defence secretary over the limitations of his defence settlement – is now unlikely to set out when the UK will meet the target of spending 3% of GDP on defence until next year’s spending review.“The world will not wait for Britain to get ready. War has returned to Europe. Missiles and drones are transforming warfare in the Middle East. Cheap weapons can now threaten cities, military bases and critical infrastructure in ways that would have sounded like science fiction a generation ago,” Badenoch said, announcing the air defence investment.“If a missile or drone is launched at Britain, we do not get a second chance to wish we had prepared.
Families can make their own choices. Businesses can build and innovate. But only government can defend the country.”Explore more on these topicsConservativesKemi BadenochDefence policyNatoMilitaryConservative conference 2026IsraelnewsShareReuse this content
