Northrop Grumman's Maritime Laser Demonstrator (MLD) is a 15 kilowatt solid state laser specifically designed to be mounted on ships. On Wednesday, the MLD underwent its first test, successfully disabling a small boat by setting fire to its motors. The range on this test was about a mile, and the laser was able to stay locked on its target despite the relative motion of its ship and the target boat in what I'd personally call heavy seas:
This is really just a first little taste of the capabilities of naval laser systems, and in a few years, the MLD is intended to be shooting down incoming missiles. A few years after that, we'll have an incredibly destructive free-electron laser ready to go. And it can't be too soon, according to the Navy:
"This is an important data point," said Rear Adm. Nevin Carr, director of the Office of Naval Research, "but I still want the Megawatt death ray."
Yep, don't we all. (wired.com)
