Laser weapons edge toward use in US military

A sci-fi staple for decades, laser weapons are finally becoming reality in the US military, albeit with capabilities a little less dramatic than at the movies.

Lightsabers—the favored weapon of the Jedi in "Star Wars" films—will remain in the fictional realm for now, but after decades of development, laser weapons are now here and are being deployed on military vehicles and planes.

Boeing, Lockheed Martin, Northrop Grumman, Raytheon—all the big defense players—are developing prototypes for the Pentagon.

The Navy has since 2014 been testing a 30-kilowatt laser on one of its warships, the USS Ponce.

Lockheed Martin has just announced a 60-kilowatt laser weapon that soon will be installed on an Army truck for operational testing against mortars and small drones.

The weapon can take out a drone from a distance of about 500 yards (meters) by keeping its beam locked onto the target for a few seconds, Jim Murdoch, an international business development director at Lockheed, told reporters this week.

But unlike in the movies, the laser beam is invisible to the naked eye.

By focusing the beam onto a target, the technology rapidly heats the inside of an incoming mortar round, causing it to explode mid-air. An impressive feat considering the round is moving at hundreds of miles per hour.

The laser weapon can also pierce the outer skin of a drone, taking out key circuits and making it crash.

For the moment, the lasers being tested are all of about this same power.

Defeating a missile

Mark Gunzinger, a senior fellow at the Center for Strategic and Budgetary Assessments, sees that relatively small output increasing rapidly.

Within just a few years, he expects far more powerful prototypes of more than 150 kilowatts.

Such a laser could knock out a missile sideways on, where it is most vulnerable.

He said special operations forces want to test such a system by 2020 on an AC-130 gunship that specializes in ground support for troops.

And within six to eight years, US forces could begin using laser systems of more than 300 kilowatts, he added.
