For the first time, a solid-state laser has successfully destroyed a flying drone in a naval environment.

The tests, performed by Raytheon with the Navy, occurred off of San Nicholas Island, Calif. over several days in late May. Four UAVs were destroyed, according to Mike Booen, vice president of directed energy.

Booen spoke with DoD Buzz in an exclusive interview at the Farnborough Air Show. The company mounted six 5.5kw solid-state lasers with a Phalanx gun system. The radar used the Phalanx’s targeting system, Booen said. And the famous guns could be used to supplement the radar.



Aside from UAVs, the laser could be used against Katyushas and other smaller rockets, as well as against swarming small boats, a growing threat to large Navy ships. Of course, the means it could, in theory at least, be used against pirates.

The effort was funded by Raytheon internal research dollars until the May shootdown, Booen said, when the Navy paid. Booen would not disclose how much the company has spent and deferred all questions about Navy funding to the service. The laser effort is not yet a program of record, meaning there is no dedicated money for it in the Pentagon budget. After additional testing, Booen said the company thought it could become a regularly funded program by 2016.

Depending on how long it can be "fired" in a burst, the range and how long it would take to recharge the capacitors (because i'm assuming it would require a fairly large chunk of energy). It could revolutionise Air Defense. Because as long as you can track the target accurately enough, you could potentially get a 100% hit rate on inbounds.

I'm assuming the power requirements would be the biggest limitations on a ship/aircraft based version.

IF you look at the video in the link it "appears" to take a few seconds to "burn" its way into the UAV so you are not looking something, at the moment, that knock repeated attacks from agile high-subsonic or supersonic missiles. It's a step forward but still not quite there.............

Yes, but that is only 32kw of laser. Thats Basically the same amount of power as you would use if you plugged 16 2000W floor heaters into the wall.

It also depends how thick the "skin" of their remote control aircraft was.

Like I said its a step nothing more nothing less...........certainly not a rule changer............

Not yet, but when they scale up that proof of concept to a deployable weapon with the power of an LM2500 powering it (or a glow in the dark power plant on the USN's carriers) then you will have serious fast knock down capability (albeit one that will degrade rapidly in conditions of cloud, fog, haze, snow, spray etc).
