Britain this week showed off a new laser weapon that its military says could deliver lethal missile or aircraft defense at around $13 a shot, potentially saving tens of millions of dollars over the cost of missile interceptors that do the job now.

Newly released video of a test of what the United Kingdom’s Defense Ministry calls the DragonFire, a laser directed energy weapon (LDEW) system, captured what the ministry says was the successful use of the laser against an aerial target during a January demonstration in Scotland.

“It’s a potential game changer for air defense,” the video says as a bright laser beam pierces the night sky over a firing range in the remote Hebrides archipelago, creating a ball of light as it hits its target.

The Defense Ministry says the DragonFire can precisely hit a target as small as a coin “over long ranges,” but it did not offer specifics. The exact range of the weapon is classified, it said.

The laser beam can cut through metal “leading to structural failure or more impactful results if the warhead is targeted,” a UK Defense Ministry statement said.

And it is claimed it also take out its targets for a tiny fraction of what current air defense missiles cost.

The Defense Ministry put the price of firing a 10-second laser burst at around $13. In contrast, the Standard Missile-2 used by the United States Navy for air defense costs more than $2 million per shot.
