The era of laser warfare may have just begun

United States Navy ships each year face many threats.  While large threats mandate heavy munitions or rockets, the majority of threats are from small motorboats with armed occupants.  Dealing with these threats is tricky -- larger munitions are potentially lethal and expensive.  But using smaller munitions places the ship's crew at risk.  Thus the non-lethal accuracy of a laser weapon would be a highly desirable tool for the U.S. maritime warriors.

Sailors' dreams of having such a weapon at their disposal advanced a step forward to reality, with Northrop Grumman Corp. (NOC) and the U.S. Office of Naval Research (ONR) completing the first live test [press release] of a solid state weapon laser at sea. 

On Wednesday the USS Paul Foster, a decommissioned destroyer, was retrofitted with Northrop Grumman's 15-kilowatt solid-state high-energy laser (HEL) prototype.  The laser creates a high-energy burst of light by running electrons through specially designed pieces of glass or crystals.

The eventual goal of the $98M USD Maritime Laser Demonstrator (MLD) is to install 100-kilowatt lasers on ships.  But the smaller 15-kilowatt system proved it might be sufficiently deadly for some applications.

Motoring into the U.S.'s Pacific testing range near San Nicholas Island off the coast of central California, the ship set its aim at a large inflatable motorboat, moving a mile away.  Firing a pulse of light, the experimental laser struck a crippling blow [video] damaging the engines and setting them on fire.  The target was crippled, floating dead in the ocean.

The success was not easy.  The scientists had to deal with ocean waves that could reach four feet in height.  And they had to deal with the day's humidity and the salty air over ocean waters.

But adverse conditions did not stop the laser from finding is mark with a killing shot.  Describes Rear Adm. Nevin Carr [profile] in an interview with Wired's Danger Room, "I spent my life at sea and I never thought we’d see this kind of progress this quickly, where we’re approaching a decision of when we can put laser weapons on ships.  When we were doing the shot and the engine went, there was elation in the control room.  It’s a big step, a proof of principle for directed energy weapons.  [Ten kilowatt beams like the test laser] can be operated in existing power levels and cooling levels on ships today."

The U.S. Navy could see deployment of lasers to warships over the course of the next decade, though their installation will require new crew training and the development of new battle tactics to fully leverage their capabilities.  Small lasers could be used effectively both against airborne targets like UAVs and against small ships that lack thick metal plating.

Northrop Grumman's rival Raytheon Comp. (RTN) has successfully killed UAVs with a laser system that couples six solid-state lasers with an output of 32 kilowatts.

In the more distant future (the 2020s, specifically) the Navy is working on a "superlaser", a megawatt-class laser capable of cutting through 2,000 feet of steel per second and offering battle-sinking power.  The more powerful ONR laser is called the Free Electron Laser.  Leveraging a new technique called free electron injection, the project has made significant progress already.

Adm. Carr comments, "This is an important data point, but I still want the Megawatt death ray."

The U.S. Navy is not alone in its thirst for laser guns.  The U.S. Air Force is also testing new laser designs that could be mounted to helicopter gunships and used to cripple UAVs, missiles, Humvees and lesser vehicles.

...who cares about non-lethal accuracy for small craft? I'd rather use the laser to kill the occupants from a mile or two out and then take control of the small craft and its contents.

Now obviously in certain cases you're going to want the occupants alive so they can be detained and questioned, but anything you can salvage from the enemy that can then be used against them is a plus.

I wonder how this will change military medicine as well. I'm certain there's going to be laser-based injuries that'll need to be treated, and I honestly don't think any physicians have extensive knowledge in that area. Then again, it may not matter when the "megawatt death ray" cuts a swath through a ship and we end up with cleanly severed heads and torsos, like the beginning of that terrible movie Ghost Ship.

Still though, its a pretty exciting time to be in the Navy. Almost makes me want to go back in.

Oh it's easy, just not cost effective. There are any number of things in the arsenal that could easily take out small craft at range, but they cost about 10 million a pop, give or take.

Lasers are perfect for Navy warfare because the massive energy source needed is already built in; the nuclear reactor.

Once we have lasers that can punch a hole through an armored warship below the waterline, hey, I'm all for this stuff. Don't see why some people are such haters.

Well I was assuming non projectile weapons. You know, anti-ship sea skimming missiles. Cruise missiles etc etc.

Or was I really supposed to assume this technology is really being developed so we can only use it against things the size of bass boats? No. It's going to be mached up bigger and bigger and advanced until, eventually, it WILL be competing directly with much less cost effective solutions. Like the before mentioned guided projectiles.

It's not really going to compete against the other guided missiles since it's going to be very range limited.

Since a laser only goes in a straight line, you're going to run into limitations with enemy ships being over the horizon when they're far away. You'll probably be limited to 20 miles or so.

If a ship is shortly beyond that, they could shoot a RIM-67 Standard at it ($400k) which is good for about 60 miles, or they could use a Harpoon ($1.2 million, good for over 60 miles), or they could use a Tomahawk (about $1.4 million) that's good for about 1,300 miles.

So let's say at 20 miles you have a few options. Lob stupid shells at the target, hoping to get a hit. Fire a million dollar missile, let's not forget the cost of the launcher systems and sub-systems and support systems...

OOOORRR warm up the megablaster!

I think saying this would "not" compete is being a bit presumptuous. Although, touche', I could be being a bit too optimistic.

It can actually be done...

You know truth be told why not station 3-4 snipers on every ship? Keep them on duty and when something goes up they fire away. I don't know how much their bullets cost but even if it costs $10 and the extra sea pay is another say $100 a month for a 6 month deployment and 1 round fired that's $610...A bit cheaper then all the other situations we've been given...

If it's anything better then a small watercraft...Well then blow it up.

My dad was always scored the highest in his marksmanship qualifications, he was no sniper mind you but he was a good shot...far from the best...I've seen him shot a bird which was flying at 100 yards away with a .22. I Trust our snipers are better shots then my dad. With that being said I'm confident they are up to par for the mission.

The power required to generate a laser pulse like this you can't just fit in a van(much less the laser itself). 15MW. Aka enough power to power several city blocks. Until we get suitcase nuclear reactors, I think we're good. And it's not like you can just hook it up to the power lines.

This technology should not be develop due to the risks of proliferation.

To late! History shows that often new ideas are developed in several places around the world around the same time, not just in one place. For example, prior to World War 2 RADAR was developed by both the British and the Germans, and at the end of the war both the British and the Germans had jet fighters. So don't be surprised if at least one other country has something in a similar or more advanced state of development.
As we saw with the American aviator who was ridiculed by military strategists for promoting the idea of dive bombing warships, I think his name was Mitchel, just because you don't want a weapons technology to be used for moral reasons or because you think it is impractical, doesn't mean people that don't like you will have the same thoughts.

As I recall, the nobles and knights of the medieval period tried to outlaw crossbows for similar reasons. It put a powerful ranged weapon in the hands of relatively untrained people. It takes years to train a skilled military archer; and weeks to train an effective crossbowman.

This weapon allows for untraceable targeted killings from miles away that conventional and nuclear weapons cannot. Output power of 25KW over a fraction of a second will easily be fatal to humans. You can fit a megawatt class generator into a van. There should be treaties banning the development of such weapons before they become a threat to our society. Providing funding for overcoming the technical challenges limiting this tech is like pouring fuel on the fire.

First off, you don't just McGyver up a home laser to assassinate someone with. Just trying to build one will get your red flagged as many of the materials needed are restricted. And his claim that a van can hold the power source, ok sure, maybe. But how are you going to GET that power supply? Wal-Mart?

Secondly, the idea that suddenly assassinations will skyrocket due to lasers is absurd. Rocket launchers are far easier to acquire and are just as deadly. How many RPG attacks have been used against a U.S President, to use his example?

Why bother spending millions on something, assuming you can even get your hands on everything required, when in all cases a .50 cal sniper rifle or hand held rocket launcher is cheaper, more effective, and easier to obtain and dispose of?

A van is pretty small for 1MW. This is a 1.4MW generator

Also, I'd like to see a report that 15kW for a fraction of a second would be fatal to a human. Even if the fraction is 1/2 and assuming no atmospheric attenuation and 100% absorption, that's only 7.5kJ of energy, enough to heat 1 kg of water 1.8 degree C. If it got you in the eyes you'd be blind, and if the spot size were small enough you'd get very serious burns, but death would probably take longer.

Now, even if 15kW was lethal, how big is the weapon? This isn't some crappy laser pointer, the size of the optics needed to collimate a laser to a small dot a mile or more range is huge. This won't be a portable weapon any time in the near future.

Compare that to a 50cal sniper rifle. In capable hands it's range is over a mile, it can be moved, set up and shot by one person if need be. Available now, and yet society has survived.

Plus, if a naval vessel wrongfully engaged a civilian vessel (even if according to the Navy's ROE it was in the right to do so), replacing motors causes less headlines than trying to recover body parts.

Spruance is a family of destroyer class vessels. Pinnace, corvette, destroyer, cruiser, heavy cruiser, battle cruiser, battleship, dreadnought etc. are classes of warship. Within those classes you have families of specialized versions of those classes.

The Spruance class destroyer is a specific subset of the Destroyer class of warship. There are many destroyers both modern and obsolete, Almost all destroyer class vessels, US and foreign, are not Spruance class ships. However all Spruance class vessels are destroyers.

To make designations more confusing the general classes designate function in tactical terms and may refer to non-naval craft such as an airship that functions as an aircraft carrier. This class is not currently in service, but has been used by air forces historically and may be revived in the modern world of UAVs.

Not necessarily. There are high temp paints out there that can survive the high temperatures. Aircraft that were designed to drop atomic bombs were often painted in antiflash white paint that was designed to reflect away the intense flash of light generated when an atomic bomb is detonated.

Besides that, not all items turn black when they burn, some have white ashes. You'll find that with aluminum covered in white paint, the heat is dissipated faster than it's absorbed in that location.

Intended use of Laser

This is a modification of the program to replace the old Phalanx CWIS systems with lasers. The original system uses a m61 6 barrell 20mm cannon.

Thr Phalanx is not deemed sufficient for the new supersonic or stealthy missiles being fielded by Russia and China. (India too, but India is no longer viewed as an opponent.) While other CIWS systems use 30mm or even 35mm shells, we use the same poor ones as are in our fighters. These lack sufficient size or flight dynamics. The Navy now seeks to skip the entire use of shells. The two replacements are the SeaRAM, which replaces the 20mm cannon with an 11-cell launcher for the RIM-116 Rolling Airframe Missile, and various laser systems in lieu of the 20mm cannon. Such systems must be capable of hitting both ships, and air targets like cruise missiles, drones, and jets. A laser system is a perfect match for our Nimitz and new Ford Class nuclear carriers.

Unfortunately that's not where modern warfare is going.

Most of the threats the U. S. Navy faces on a daily basis are from these small boats, not from some destroyer. Somali pirates, Iraqi insurgents attacking, or attempting to attack the Al Basrah oil terminal, all use small craft like this. USS Cole? Small craft.

Right now, this laser could be mounted on many Navy and be a benefit to the crew.

The only possible way we're going to need the weaponry to sink a destroyer or larger is if we entered into a war with China or Russia. That won't happen for awhile, if ever.

Especially considering electronic warfare is more crippling to a large enemy.

I was impressed by the pics in the article. But if you actually look at the video, it happens so slowly... definitely less impressive. Any pirate worth their salt would be able to dodge once they realized what was happening. Or get out a mirror...

I don't know, it seemed to take about 5 seconds from the time that the laser hit until the motor caught fire. You very well might not notice that until it's too late, especially since you're likely concentrating on that big steel warship bearing down on you. If the production version halved the time, there would be almost to time to react.

It was a proof of concept test with a 15 kW laser. It was more about target acquisition and tracking a small target bobbing up and down in 4 ft swells. Production models are to range from 100 kW to 1 MW.

Since it could lock on and track in 4 ft swells, it is highly unlikely any sea craft could maneuver away, regardless of a pirate's salinity.

Mirrors are not 100% reflective. A typical mirror has around 85% reflectance. Really expensive laboratory quality mirrors might reach 95%. 15% of 100 kW is 15 kW. So if the motor was protected by mirrors, a 100 kW laser would do to it what the 15 kW laser did to the black painted motor.

Of course, since you can't see the laser at all, you wouldn't know they were firing until your motor caught fire.

This entire test screams anti-pirate weaponry to me. I doubt they plan to use lasers any time in the near future against hardened targets; planes and missiles are just so much more effective than a weapons system where you have to get into close visual range.

I see this being used on destroyers patrolling in areas like Somalia where you have a number of small, fast, maneuverable craft filled with heavily armed occupants. Rather than try to take them out with the big guns, you disable the craft and bring them into custody.

So now the US Navy resorts to cannibalism? Well I guess if the Democrats could do as they wished to the military, they might have to resort to that.

The last direct, successful attack of a US Navy ship, the USS Cole, was done by a small skiff like this. And it left 17 people dead and a rather large hole in the side of the boat.

He didn't say lasers would have. He's simply pointing out to the OP that small vessels can still be threats.

You'd think this kind of reasoning would be common place....Idiocracy takes one more step towards the realm of reality.

Lasers wouldn't have made any difference with the Cole. They saw the boat approach, but were not allowed to fire upon them due to their rules of engagement.

Also our warships have plenty of weapnos to take out small boats, like .50 cals etc. Lasers will be useful once they are higher power, can repeatedly fire w/o overheating and have their targeting figured out.

This weapon is not ment for ship to ship combat, atleast not large ship combat. There's plenty of threat from small ships, and you don't try to hit those with 19 inch guns. Especially when you might want to not kill the people on board.

This weapon however is made for large ship to ship combat and is developped for just that reason:

Laser my ass. I'll take 2 of these.
