U.S. Navy Successfully Uses Laser to Shoot Down Drones

Posted by Charles Cooper

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.

These sucessful tests of the Laser Weapon System on moving targets of a naval ship are definitely encouraging, but, I understand that lasers have major problems working in adverse weather conditions,i.e. heavy fogs, heavy squalls and rainfalls, etc.
Do some of you more knowlegeable people have any clues on whether or not, they have found answers to these problems?

Raytheon is an unknown quantity at this point

I think that this systems would not be practical for a naval ship,because the time of reaction is 20-30 sec,i think Phalanx 20mm + SEA RAM are good choice,but for defending ground targets from artillery shells or rocket artillery on the ground can prosper.

Another problem would be the energy-some ASBM are deflecting laser beams but if the laser is enough potent then it won't be a problem-and this means a lot of energy but imagine a rocket is guided to the ship so here every second is important and is far more difficult to launch another missile interceptor or to react with cannon-for example harpoon is traveling over 240m/second so it's hard to intercept(not to mention P-800) so really instead of launching and shooting a better option is to use HEL(high energy laser)-this Laser phalanx version that destroyed the drones was 50kw,but for tactic Anti ship missiles it must be 3 to 4 times more powerful because Heat Resistant Coating Layers (HRCLs) that are now installed on Tactical Antiship ballistic missiles this lasers are often Oxygen iodine lasers(chemical) and the good news is their range-more than 15km another morepowerfull lasers is again chemical but they use deuterium fluoride carbon dioxide which is Megawatt powerful laser-well this is IT-range more than 10000km(in space 500 000) but they are heavy and expensive but if it can save life's then their use is OK.

They often have energy burst that lasts 3-5 seconds,and one laser has capacity for minimum 15 pulses which means the target will come in sight.

it's wort pointing that Megawatt lasers work in micron wavelenght -meaning they can be used against variety of targets.
