NATIONAL HARBOR, Md.–The Navy’s top officer unveiled new technology Monday that allows ships to shoot down drones or other vehicles for about the cost of a pack of gum.
The USS Dewey tested an onboard laser weapons system in July 2012, in which it successfully shot down a test drone. Navy Adm. Jonathan Greenert, the chief of Naval Operations, screened video of the event while speaking at the Sea-Air-Space expo.
