the high-energy laser hit more than 90 mortar bombs

That could have saved a lot of lives in Iraq and Afghanistan. I hope it actually works. Not a huge fan of the tests. Let me know if it works in the field.

"If you're engaging a target at the same range, a 100 kW laser will destroy the target in one-tenth of the time than the 10kW would," said Terry Bauer, a program manager at Boeing, the lead contractor on the project.

Terry is also an active member of the No Sh*t Sherlock Basic Physics club.

Unfortunately it missed the other 910...

Nah actually this will work, just need a dependable and powerful enough lasers. They're wedding the high-speed tracking and targeting radar of the naval CIWS (Close In Weapon System, designed to kill high speed incoming missiles) which is 30+ years old now with a gun that fires bullets moving a tad faster than a 20mm Vulcan round. Or at least I'm assuming what that is, they were also testing pretty much a straight up CIWS still with the Vulcan to shoot down incoming mortars and the video I saw certainly made it look pretty successful.

Like Billy Mitchell's bombers marked the end of the battleship and the line of battle as the ruler of the seas, this tech is going to eventually end the days of artillery as the queen of the battlefield. Or at least it will definitely be the end of dumb plain ballistic artillery. I assume they'll figure out how to teach the next MLRS' missiles to fly evasives, but not sure even that will be enough to beat a really fast-thinking and tracking laser armed close defense weapon.

I knew someone who was in anti-mortars (verbiage?), but never talked enough with them about it. They can pinpoint the location after a few rounds go off. I, very briefly, thought the CIWS might be a good idea, but that was quickly sh*tcanned when I realized those rounds have to land somewhere.

I hope they can get it to work.

I'm sure these guys are on the case:

That's different, that's going after the platform firing. Since the '70s there has been tech to track incoming artillery rounds, calculate the point they were fired from, and send a little counter-battery fire hello of your own back at them. Which of course is why all major players' heavy artillery is highly mobile as it's fire one or two salvos and get moving before the other guy's artillery lands on you.

That won't go away. Still a good idea to try to kill the platform or at least keep them constantly moving and wasting time not firing.

TFA is terminal defense, and honestly when it gets to the point that every company has a couple Strykers with I'M A FIRIN' MAH LAZER close in defense, I don't see how artillery is going to be viable except for saturating defenses with lots of little smart munitions. Which will still work reasonably well against vehicles and troops, but won't be much good for blowing big stuff the fark up.

They had Centurion, which is sort of a ground-based version of the Navy's Phalanx CIWS missile defense system at some of the major FOBs in Iraq.  No idea what advantages a laser has versus a 20mm cannon.

Yeah that was what I remembered with the CIWS. Although yes the rounds were designed to detonate whether they hit anything or not so you didn't have to worry about anything but tiny bits coming down, I remember the engagement times being several seconds at least to ensure a kill. Have to think that given time a laser-based systems would make kills quicker and therefore be able to engage more simultaneous targets with less warning. And given enough electricity, probably considerably greater endurance than even a multi-barrelled gatling. Plus, they're lasers. Yes, Phalanx is cool all on it's own, but, you know, LASERS.

I'm going with range and speed. Light does travel a bit faster than slugs and gravity has less of an effect on light.

It might mean the end (or the deminishment) of sneaky little one or two mortar raids, but if you had three or four,or, in a major war (US vs. China?) scenario, dozens of batteries of ballistic artillery pieces?  You would probably overwhelm the defense system, and 155 ammo is (relatively) cheap.  Will this stop a couple of guys with a mortar tube and 10 rounds?  Sure.  A couple of well supplied batteries of M777s in rapid fire?  I doubt it.

At battlefield ranges, laser weapons only have to find their targets in two dimensions instead of four.

So they fire a laser at an point in the sky from which they expected mortars to come and some of those mortars were destroyed? They caused a massive section of sky to become a no-fly zone including the patch of sky where the drones we have can watch for mortar launches, spent an awful lot of money, and likely only took out a small percentage of the mortars?

Meanwhile: the insurgents loaded their mortar on the back of a Toyota Hilux and drove to the flank of the firebase they were attacking and started over their assault while the DoD boffins spend half an hour retasking the laser to fire in the other direction.

I see one or nine flaws with this thing. Besides, the tech already exists to pinpoint mortar launch co-ordinates. Get that deployed properly and one small team could simply fire back in a few seconds thereby rendering the laser largely redundant. The first shot is always the one that's most effective, it's stopping the second one that's the key. The laser might destroy the subsequent mortar rounds, but firing back quickly could prevent them from being fired at all.

It will stop the crap from the insurgents and the like but it won't stop a serious attack by an enemy who designs their shells to get through:

1)  Design the shells to salvage fuse when they're burned by the laser.

2)  Put some chaff in the shell, probably in it's tail where it's not going to impair the effectiveness.  (Energy going out it's tail normally goes up into the sky.  Shrapnel thrown by it won't hit anything anyway.

This of course does nothing to stop the interception of the shell.  In fact, the salvage fusing makes it a bit easier (the salvage fuse will have to trigger before the laser burns the charge inside.)  The issue is with the next shell--it's coming in behind that chaff cloud left by the first one and thus is harder to track.  So long as the shells are aimed at the laser they will eventually get through.  (If the defenders have a bunch of lasers spread over an area you need to simultaneously engage them all.)

So the Navy is installing a laser system on the USS Ponce, that's truth in advertising and congress probably wouldn't let them go with USS Hershey Bar Shooter. www.stonewallvets.org

The one advantage I'd think would be less crap raining down all over the place creating potential pollution.

Granted, I get the whole we don't want the big explosive device hitting us, and I agree, but if you could do the same with less shrapnel falling out of the sky and lead hitting all over the place from the thousands of rounds those shoot out (unless I'm mistaking it for the mini-guns the navy uses), why not do it.

Besides, energy weapons on platforms like that is probably the future.
