So this is the laser gun the navy wants.
Called the FEL -- for free-electron laser, which doesn't use a gain medium and is therefore more versatile -- it was tested in February consuming a blistering 500 kilovolts of energy, producing a supercharged electron beam that can burn through 20 feet of steel per second.
This is a test firing of a smaller demo.
A futuristic laser mounted on a speeding cruiser successfully blasted a bobbing, weaving boat from the waters of the Pacific Ocean -- the first test at sea of such a gun and a fresh milestone in the Navy's quest to reoutfit the fleet with a host of laser weapons, the Navy announced Friday.
"We were able to have a destructive effect on a high-speed cruising target," chief of Naval research Rear Adm. Nevin Carr told FoxNews.com.
The test occurred Wednesday near San Nicholas Island, off the coast of Central California in the Pacific Ocean test range, from a laser gun mounted onto the deck of the Navy’s self-defense test ship, former USS Paul Foster.
In a video of the event, the small boat can be seen catching fire and ultimately bursting into flames, a conflagration caused by the navy's distant gun. Some details of the event were classified, including the exact range of the shot, but Carr could provide some information: "We're talking miles, not yards," Carr said.
The Navy set fire to a bobbing and weaving boat with a new laser gun mounted to a cruiser -- a first-of-its-kind test that moves the prototype closer to reality.
The Navy, Army and other armed forces have been working to incorporate so called "directed energy" laser weapons in a range of new guns, from tank-mounted blasters to guns on planes or unmanned balloons. But this marks the first test of a laser weapon at sea -- and proof that laser rifles are no mere Buck Rogers daydream.
“This is the first time a [high-energy-laser], at these power levels, has been put on a Navy ship, powered from that ship and used to defeat a target at-range in a maritime environment,” said Peter Morrison, program officer for the Office of Naval Research.
"The Navy is moving strongly towards directed energy," Carr told FoxNews.com.
The weapon, called the maritime laser demonstrator, was built in partnership with Northrop Grumman. It focused 15 kilowatts of energy by concentrating it through a solid medium -- hence the name.
"We call them solid state because they use a medium, usually something like a crystal," explained Quentin Saulter, the research office's program officer. It was used in Wednesday's demonstration against a small boat, but Carr told FoxNews.com that this and other types of laser weaponry could be equally effective against planes and even targets on shore.
"To begin to address a cruise missile threat, we'd need to get up to hundreds of kilowatts," Carr said.
20 feet of steel per second? I am speechless.
