Navy successfully demos a ship-mounted High Energy Laser (HEL)
I was expecting spectacular explosions, a la Star Wars, so I was slightly disappointed by their absence. Regardless, this is pretty cool technology!
This is the first successful use of the Navy's Marine Laser Demonstrator (MLD). It's a ship-mounted High Energy Laser, developed by the Office of Naval Research in cooperation with Northrup Grumman, which was fired at an unmanned motor boat. More info is here.
