these will become more and more common in static locations like the white house and airports. terrorists and hostile nations would benefit greatly from getting 1 lb of RDX in front of a 747 just before landing 200 feet up.

The problem is the lifelong blinding of other people in office buildings when the attacker is low on the horizon. (or lasing up the aircraft your trying to protect.) And for this specific naval application, the NAVY likes ship-board weapons systems to survive near misses from 500lbs warheads. optics of this type i suspect would not. dwell time would, as the article suggests, is the real question.


once i get the props, and large quad 20km kickstarter finished, id like to investigate ultra-high power lasers presumably electric arc

...that just reminded me of james may , dazzle camouflage documentary a while ago .
war ships had weird paint jobs that arent blending into environment but optical illusions .




back to laser , I find it strange how today a person can think its ok to shine a $2 shop laser pointer at the cockpit of a plane
, still happens here in nz .

some peole are missing some thing and unfortunate for the rest of us , one cant simply get IT from any where

These are still illegal under international law. People no longer regularly nuke places for the same reasons. Additionally, there are serious ethical implications of escalating directed energy weapons technology. America has a public image problem, and the perceived strategic deterrent will assuredly create more problems than it can solve. Although the majority of people agree blinding/burning people is wrong, there may be additional problems as is actually written doctrine in some religions that this type of war is prohibited without exception.

Indeed, both the early Nazi-party members and Japanese-emperor never considered Eisenstein's ideas would end the war, and create hundreds of other problems in the past century. Accordingly, I doubt such an individual would hold a country that force feeds prisoners though their anus in high regard.

The US NAVY really needs to worry more about Under Sea Vehicles then UAVs. If i were an enemy, that's how id do it. The laser may sort of be useful in ports.

unless theres some magic wand classified defense system we dont know of, a rolled-over-the-side torpedo /UAS in a port would be difficult to defend against. it could even lay in wait, unlike a normal torpedo. given the noise in a common port, they'd be nearly impossible to detect.

This is not the thread on automated trolling.
Patrick has a crass sense of humor most engineers appreciate.


@Patrick
What was done to a completely innocent German citizen did not serve any medical purpose, and is currently officially classified as sexual assault according to a US medical panel.

“The loss of the moral high-ground makes wars unwindable” (1994 CIA strategist)
The current media narrative for the past decade seems to try to redefine what “moral” implies rather than face the question in honorable discourse.

The real problem of Realpolitik is not a technical one that needs solved, as even a mad-man can attest:
"Wer mit Ungeheuern kämpft, mag zusehn, dass er nicht dabei zum Ungeheuer wird. Und wenn du lange in einen Abgrund blickst, blickt der Abgrund auch in dich hinein." (Friedrich Nietzsche)

Through the miracle of the great all knowing Google:

"He who fights with monsters might see to it that he thereby become a monster. And if you gaze for long into an abyss, the abyss also looks into you of."
(Friedrich Nietzsche)

yeah but here at Chico State we have "beer colon consumption", (which often results in alcohol poisoning). If a nations youth willing subject themselves to this treatment, is it really torture?

In any case, Diane Feinstein (D) from Commun-fornia, has no business criticizing the tactics used in the past. She was not only aware of, but signed off on (EIT's) with great vigor. The only senator or representative who ever really made the moral or legal argument was Jane Harmon, also (D-CA) and she did so while the smoke was still going up. so spare me Diane's false tears, now that were conveniently far enough away from 9/11. Remember, we Americans had seen Anthrax, high jackings, building collapse, and anyone with a brain was worried if the next week or year we'd see worse.

Any true war (of any real length) has involved "questionable" acts. (with a few exceptions like the 6-day war) I fully admit its possible for nations to go to far. like the Russians captured by the Germans. Or the Americans captured and murdered by the Japanese.

Re: US navy laser
Carbon_Rod, Tue Dec 16 2014, 09:31AM

Indeed, rhetoric to re-frame the context of atrocities is not new. The horrendous crimes of WWII Japanese prison camps were notorious, and after the war ended it took many years for people to forget rather than forgive. The only exception was that the people performing the water-boarding on our soldiers served jail time for their acts under international law. Rest assured, people were not concerned about the technical sophistication of the bucket used in the act.

I still predict that "the enemy" will buy lots of silver paint.

Re: US navy laser
Patrick, Thu Dec 18 2014, 04:14PM

kapton and silver paint as with the black hawks, maybe to sacrificial fiberglass asbestos insulation. even 0.5 mm would greatly reduce this systems effectiveness. High temperature epoxy and glass fiber would take alot to punch through. presuming the small drones this system would take on, they'ed be on a one-way-trip, so failing to intercept would be failure to be worth carrying.

shooting the drones we've seen on test footage, we dont know how well they're built. Hire me to be the Red aggressor and ill build a real drone with real attack potential, then we'll see if they can down it. something tells me they want the money but dont want a fair demonstration. Im all for a time of development to bring a system up to capable, but its all suspicious to me.

The Phalanx rotary cannon can take on anything larger, with no paint out-witting 20mm incendiary explosive rounds. For micro drones perhaps 300 cal or 5.56mm NATO round version for that added poof factor, and still be quick to bare aganist pop-up targets.

the biggest threat to air space and nat secuity is pilot training colleges , they operate 5 days a week!

Re: US navy laser
Patrick, Thu Dec 18 2014, 10:40PM

why bother with the college, its all controlled by the attacker. the attacker chooses when, which method and how much effort goes into the individual attempt. Harbors would be easiest to make an attack from.

they could send a 20 drone swarm, that'd be hard to down before enough got through. with modern weapons systems, like lasers and phased radar, 1 kg or pound of RDX closely put in, destroys the weapon system. then like battleships, your not really able to take part in modern sea warfare just float around and watch the battle. the ship would otherwise be left nearly unharmed, this would be the worst case for a superpower with shiny expensive toys, and the best case for a weak-whiny-flimsy nation.

even if this particular attack fails, the flimsy nation could just wait a week, month, or year and swing again.

no need to dump a 500 lb bomb or hurl a 1000lb exocet to kill the whole missile carrier anymore.


civillian airports would be even easier to attack, non maneuvering targets! radar, ILS, tower, aircraft parked. runways dont move, and you can cross the fence with 10 drones, and be gone in your car driving away (DC Sniper) before the first boom goes off.

3 drones with Gold Foil Retroreflector Prisms on all sides could quickly redirect the beam back at the vessel or civilians.
The people that designed this are assuming an enemy is more mentally deficient.

Is it a drone... or a taxidermist's fake eagle... its very illegal to shoot at eagles...

Re: US navy laser
Andy, Fri Dec 19 2014, 05:40AM

Don't know about the laser, but the upscaled h&k311 with caseless rounds, tops 2100rpm 10 years ago, with a discovery channel a newer version with 10krpm and about 1k rounds.
Even with 2.57mm NATO rounds with 10k in the air in a second, then just reload.....

Wouldn't expect to much weapons to target a undersea remote controled version, a opaqe or what ever laser to water, would be better than a sea sprite.
