Britain should install an Israeli-style “iron dome” missile defence system, Penny Mordaunt has suggested, in an unusual intervention highlighting concerns within the government about the increasingly unstable geopolitical landscape.

Ms Mordaunt, the House of Commons leader and a former Royal Navy reservist, again called for an increase in defence spending, saying the government has a “duty to our citizens” to keep them protected as the world becomes less safe.

The UK currently spends just over 2 per cent of GDP on defence, but there are growing calls for this to be increased to at least 2.5 per cent, with some figures pushing for as much as 3 per cent.

Writing for The Sunday Telegraph, in a piece that could be interpreted as a pitch for the future leadership of her party, Ms Mordaunt said the UK must be more ambitious about the amount of resources it puts into defence.

“To those that say, about our defence ambitions, we ‘can’t do’, ‘shouldn’t do’, or ‘can’t afford to do’, I say ‘Look to Israel’ – a nation a fraction of our size that has staved off an attack from a nation 10 times its size,” she told the paper.

The Iron Dome system, developed with backing from the US, specialises in shooting down short-range rockets. It has intercepted a vast number of rockets since it was activated early in the last decade – including thousands during the current war against Hamas and Hezbollah. Israel says it has a success rate of over 90 per cent.

The Iron Dome is supported by the Arrow system, which is designed to intercept long-range missiles including the types of ballistic missiles Iran said it had launched against Israel.

The defence system is extremely expensive to maintain and operate. Reem Aminoach, a former brigadier general and chief financial adviser to the head of the Israeli military, told Bloomberg that it would have cost Israel around $1bn (£808m) to thwart Iran’s attack, with some interceptor missiles costing $3.5m (£2.8m) alone.
