nmrsnr: The reason laser weapons are not particularly practical: Retroreflectors.

They are also the only weapon that can be defeated by sufficiently white paint.


From what I've read that's not a serious concern as the lasers are powerful enough to simply burn through white paint and reflectors are both too heavy and too hard to maintain. A coating reflective enough to bounce a 30 kw laser wouldn't stay clean or unscratched long while exposed to the elements.

"For the United States, thanks to pioneering efforts of American companies like Lockheed Martin and the military, laser weapons are no longer the stuff of Star Wars and Star Trek. "

Want to know more?

Seriously, this reads like a pamphlet from the Lockheed both at Farnborough.

mrshowrules: fireclown: mrshowrules: So as long as the enemy uses drones with a matte finish, stick to the flight plan, on clear days and maintain a constant speed, they don't have a chance.

That's how it is TODAY, yes.

I haven't seen significant advancement since I was 8 years old.  Rail-gun technology has more potential.


I don't know shiat about fark-all, but railguns and battlefield lasers seem to have different applications to me. Like, you use a railgun when you want to dump a couple megajoules of energy into a target all at once, and a laser is for when you want to make a neat hole in one particular part of a target. Shooting a rail gun at a drone seems to be like shooting a .50 at a sparrow.

HoratioGates: mrshowrules: I'm also talking out of my ass a bit.  The drone isn't the target.  If it was, you could simply use cheap radio jamming equipment.  The drone is a proof of concept.  The goal is missiles.  They already have shiat to take out jets very effectively.  Since the St. Ronnie days, the golden grail is to take out a nuclear missile with a laser.  Not going to happen.  Missiles move to fast, and are too shiny to keep a hot enough laser beam on them long enough to destroy them.  Heck, the missiles have heat shielding on them also because of the air friction.

That's got me thinking... what spectrum would you need to go through the heat shielding but not the uranium.  Heat the uranium to prematurely detonate the charge.


I... don't even know where to begin with this.

Egoy3k: 'real lasers are invisible'

You know what? fark it. I don't care anymore, just say whatever you think is correct. Make definitive statements about shiat you don't understand and speak with authority about them because who gives a shiat anymore? fark your journalistic integrity, fark your viewers or readers fark it all, doing shiat like research is farking work and fark that.


Meh, I give them a pass if at the end of the day people have a closer expectation of reality than before.

Yes, the author could have said "unlike in films an observer would not be able to see the light of the laser as it was fired. Lasers are highly collimated, meaning that they do not disperse in vacuum, an have very little to bounce off of in regular air. As a result, unless you were in the direct line of fire of the laser you wouldn't see the shot, rendering the laser effectively invisible."

But explanations are hard, invisible lasers sound cooler, and at the end of the day, the average person would takeaway that this beam weapon won't look like Star Wars.

In near-term future battles, the U.S. military can choose to bring laser weapons mounted on vehicles, vessels, and more, to war. By comparison, the weapons of any enemy will look like bows and arrows.

How do you feel about spears and shields?

mrshowrules: Know a rail gun can deliver a tremendous about of energy that will definitely destroy a missile. It just can't hit it because even a projectile at Mach 5 is too slow to reliable hit a far away target moving at similar speeds. You can't hit a bullet with a dumb bullet that can't steer. Except a rail gun has more potential. The projectiles could be made faster and faster and they could be configured in larger and larger arrays and they could be fired in rapid secession. Simultaneously, you will improve targeting ability. So one day, you could point a rail gun at an ICBM 500 miles away with an array that shoots 100 projectiles (a millisecond) at Mach 10 and eliminate a missile.


Boost phase intercept is the more straightforward application for a railgun.

Velocity is a HUGE consideration when tracking a moving target, be it a drone or a ballistic missile. It's hard as hell to shoot a ballistic missile as it arcs over head because you're chasing it from behind and below. Hitting it with a laser is as simple as pointing the laser at it (and leading by maybe 1 millisecond's worth of travel if it's 200 miles above).

For a drone, yes, the laser would be overkill from that perspective, but I can imagine in a lot of urban environments it might be better to blast a couple laser shots upward than to expend a thousand rounds of CIWS in a vertical direction. I am not sure how the rail gun plays into this, though.

WTF? Forget the lasers. I was too distracted by that horrible farking article written at about a 3rd grade reading level by someone who was obviously fapping furiously to the thought of the US military kicking some foreign ass.

I expect mainstream news outlets to be kind of dumbed down, but holy crap. Fox is going to be at "See Spot run" levels pretty soon.
