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.

DragonFire: UK laser could be used against Russian drones on Ukraine front line

27 minutes ago

A UK high-power laser weapon could be sent to Ukraine to take down Russian drones, the defence secretary says.

According to Grant Shapps, the weapon could have "huge ramifications" for the conflict in Europe.

The DragonFire weapon is expected to be rolled out by 2027, but Mr Shapps said he wanted to "speed up" production and make it available sooner.

It follows a successful trial of the laser, carried out against an aerial target for the first time in January.

The laser was originally expected to be operational by 2032, but new reforms intended to speed up government procurement of weapons mean that it will now be ready five years earlier.

Directed energy weapon replaces million-dollar missiles at 13 cents a shot

A new directed energy weapon is being rolled out to bolster British defense capabilities. And, at 13 cents a shot, it's just as effective, but a lot cheaper than the multi-million dollar missiles it's designed to replace.

The Radio Frequency Directed Energy Weapon (RFDEW) is part of the British government's policy to respond to a changing geopolitical situation, placing the country's defense on more of a war footing as it increases spending to 2.5% of GDP by 2030. This policy change also includes fast-tracking the rollout of lasers and other directed energy weapons.

The latter is extremely important, because, well, knocking out a drone that costs a few grand with a missile costing millions of dollars per round is bad economics – see, for example, the US$1.3-2.5 million Sea Viper missile used to take out a US$20,000 drone, as reported by Navy Lookout. Also, missile stockpiles tend to be pretty small, and swarms of cheap drones could easily exhaust them.
