Laser Weapon System

Laser used for test

For years, the U.S. Navy has been pursuing a workable ray gun that could provide a leap ahead in ship self-defenses. Now, with a series of tests of a system called the Laser Weapon System, or LaWS), it may be one step closer to that goal. Naval Sea Systems Command (NAVSEA), the service's technology development arm, announced today that LaWS had "successfully tracked, engaged, and destroyed" a drone in flight, during an over-the-water engagement at San Nicholas Island, California.
