Israel’s new laser missile-defense system has successfully intercepted mortars, rockets and anti-tank missiles in recent tests, Israeli leaders said Thursday.

The Israeli-made laser system, known as the “Iron Beam,” is designed to complement a series of aerial defense systems, including the more costly rocket-intercepting Iron Dome.

“This may sound like science-fiction, but it’s real,” said Prime Minister Naftali Bennett. ”The Iron Beam’s interceptions are silent, they’re invisible and they only cost around $3.50” apiece, he added.
