http://www.foxnews.com/scitech/2010/06/03/navy-shoots-aircraft-really-big-raygun/The U.S. Navy has a raygun -- and it's a big one.
In a red-letter week for the military, the Naval Sea [COLOR=blue !important][COLOR=blue !important]Systems[/COLOR][/COLOR] command "successfully tracked, engaged, and destroyed” several unmanned aircraft with its Laser Weapon System, otherwise known as LaWS. and on the ground, iRobot unveiled its gift to the Pentagon -- the 710 Warrior designed to clear an entire 45 square meter minefield in one blow.
But first, the raygun.
According to The Register, "it represents the first Detect-Thru-Engage laser shoot-down of a threat representative target in an over-the-water, combat representative scenario." LaWS is fitted to the Navy's "R2-D2" robotic gun turret and looks every bit like what you'd expect a raygun to look like.
