U.S. Navy Laser Weapon Shoots Down Drones [Copy link] 中文

During a recent test, a Navy laser using a tracking system from Raytheon shot down four unmanned aerial vehicles

In a grainy, black-and-white video that looks like a home movie of a UFO attack a sleek aircraft streaks through the sky one minute, only to burst into flames the next and plummet into the sea. The silent video, which Raytheon Co. debuts Monday at the U.K.'s Farnborough International Air Show 2010, however, is not science fiction. The defense contractor says it depicts part of a test conducted in May during which the U.S. Navy used a solid-state laser to shoot down unmanned aerial vehicles over the Pacific Ocean.

During the test, the Navy's Laser Weapon System (LaWS), guided by Raytheon's Phalanx Close-In Weapon System sensors, engaged and destroyed four UAV targets flying over water near the Navy's weapons and training facility on San Nicolas Island in California's Santa Barbara Channel, about 120 kilometers west of Los Angeles. The Phalanx—a rapid-fire, computer-controlled, radar-guided gun system—used electro-optical tracking and radio frequency sensors to provide range data to the LaWS, which is made up of six solid-state lasers with an output of 32 kilowatts that simultaneously focus on a target.

Truly amazing, and shocking too

here is a CBS report and a photo (seemly untrue) from Raytheon, one of the laser developer

http://www.cbsnews.com/8301-501465_162-20011041-501465.html

The U.S. Navy has used a a laser weapon to shoot down four unmanned aerial vehicles in a test that rings up memories of Ronald Reagan's "Star Wars" missile defense shield in the 1980s.

The successful test of the Laser Weapon System off the coast of California was announced during the Farnborough International Air Show, which is taking place this week in England.

The technology, jointly developed with Raytheon, used industrial strength lasers, is more than just your run-of-the-mill PR exercise. In its write-up of the technology, Scientific American correctly notes that the shoot-down of the drones over water constitutes an advance over previous Raytheon tests which focused on static targets.

Mike Booen of Raytheon gave USA Today the money quote for the day: "The targets came in over the ocean, and it was a good day for lasers, bad day for drones."

Still, don't expect deployment any time soon. Even if the follow-up tests come through with flying colors, the technology is likely going to take several more years before it's ready for combat situation. (Coincidentally, the breakthrough made the rounds on the anniversary of the day that U.S. astronauts walked on the moon in 1969.

US is decades ahead of any country in the world

Especially in military technology

I'm skeptical as to whether laser indeed are capable of conducting energy sources sufficient enough for it to be able to knock out a craft in the air -- any kind of a craft -- ...  My suspicion centers around the science/theory of electromagnetic pulse radiation that zaps (microwaves) chip components aboard a flying object, any flying object, hence rendering it null...  this is among one of the sciences that china is suspected of engaing going back, wat back, to 2001.
Putin's a killer. This was the claim made by Fox News journalist; Bill O'Reilly during his recent interview with Donald Trump. Trump's reply came in the form of a simple question. What, you think our country's so innocent?

Try telling this to magnetic who thinks that the "Sunburn" is the answer to all China's anti N problems.

I hope everyone remains skeptical and doesn't believe it.  Surprise is the best tactical advantage.

I certainly think it's feasible.  The video looks real: the smoke begins slightly before the spots glow due to heat, the hot spot moves along the body slightly before settling down, and once the spot settles down it begins to puncture the fuselage and things start catching on fire internally (whereas if it were due to chemicals within the fuselage, the insides would catch fire first).  It takes some time before the drone loses control.  It doesn't look like a aluminothermic reaction.  The capability of creating such a laser has been technologically possible for a long time.  The trick was making it practical which it seems they have done.  32kW is not very much.
