A laser-based air defence system that hopes to deploy from next year to neutralise enemy rockets and drones will cost just $2 per interception, Prime Minister said on Wednesday.

currently depends on shoot-down systems that launch interceptor missiles costing between tens of thousands and millions of dollars to track such projectiles.

But the Iron Beam system, a prototype of which was unveiled last year, uses lasers to super-heat and disable aerial threats.

Bennett predicted it would enter service by early 2023.

"This is a game-changer, not just because we are striking at the enemy military, but also because we are bankrupting it," he said during a visit to the system's state-owned manufacturer, Rafael Advanced Defense Systems.

"Until today, it cost us a lot of money to intercept each rocket. Today they [the enemy] can invest tens of thousands of dollars in a rocket and we will invest $2 on the electricity for intercepting that rocket," Bennett said in a video issued by his office.

Palestinian groups have retaliated to Israeli attacks by firing rockets and mortar bombs at Israel. Israel has also intercepted drones it suspects were launched by Iranian-backed fighters.

Israel has also fired repeated barrages of missiles, particularly at besieged Gaza, where in May 2021 a brutal 11-day Israeli bombing campaign . Rocket fire from Hamas and other Gaza militants killed 13 in Israel.
