Navy Unveils First Active Laser Weapon In Persian Gulf (cnn.com)

schwit1 shares a report from CNN: In the sometimes hostile waters of the Persian Gulf looms the U.S. Navy's first -- in fact, the world's first -- active laser weapon. The LaWS, an acronym for Laser Weapons System, is not science fiction. It is not experimental. It is deployed on board the USS Ponce amphibious transport ship, ready to be fired at targets today and every day by Capt. Christopher Wells and his crew. It costs "about a dollar a shot" to fire, said Lt. Cale Hughes, laser weapons system officer. LaWS begins with an advantage no other weapon ever invented comes even close to matching. It moves, by definition, at the speed of light. For comparison, that is 50,000 times the speed of an incoming ICBM. For the test, the USS Ponce crew launched the target -- a drone aircraft, a weapon in increasing use by Iran, North Korea, China, Russia and other adversaries. In an instant, the drone's wing lit up, heated to a temperature of thousands of degrees, lethally damaging the aircraft and sending it hurtling down to the sea. "It operates in an invisible part of the electromagnetic spectrum so you don't see the beam, it doesn't make any sound, it's completely silent and it's incredibly effective at what it does," said Hughes.

Granted, if it's a 50kw laser then it doesn't need to reflect very much for very long to damage someone looking right into the reflected beam, but I still think the usefulness and practicality of actually fielding a target with reflective armor which a laser would fire at is vastly overstated.

      Completely incorrect. You can find ample information on the topic from now-public documents of the former SDI program.

      Lasers do not have infinite energy. In order to apply the effect you want (whatever that is), you need to leave it on the target for a characteristic "dwell time". That is normally on the order of 1 to 10 seconds. Mirroring the surface of the target can increase this about 1 to 3 times. Adding an aerosol fog can do that again. The idea is not to completely defeat the laser, but make it take so long to work that the target beside it remains untouched simply because you run out of time.

      The other thing to note is that the tracking systems pointing the laser are far from perfect and the beam tends to "wander" over the target. Generally, only some part of the target receives continual energy. In that case, the mirrored portions will reflect enough energy to eliminate any effect, as they will cool off when the beam moves off that spot again. While the main target area doesn't have this advantage, it might mean the hole you punch is too small to be useful.

      And finally, there is the movement of the target itself. This is gross movement, like spinning the rocket booster of an ICBM or turning your boat back and forth across the path to the target. This only works if the dwell time is fairly long, otherwise, the laser will do its damage while you're still maneuvering. Adding mirroring can stretch that time enough to make such gross movements practical.

      Combining these techniques, mirroring, aerosols and spinning, it was pretty obvious any sort of space-based chemical laser would not work against ICBMs. Against boats is another matter, but given the extremely low power of this device, and the obviously faked tests I've seen, I suspect it is essentially useless for anything other than drones, which can't really combine these effects usefully.

It's just stupid. A coat of spray paint is not going to protect you from a 50kw laser, chief. Not even a little bit. There are going to be so many imperfections in that surface that will absorb the energy from the laser and burn up, causing distortions around them which will do the same, it will be a runaway effect and your so-called "protective coating" is going to be a cloud of fine particles floating around the target as it gets destroyed. A protective coating will also possibly be fatally flawed if the surface has any dust, grease, oil, bug guts, water, etc on it. It's absolutely idiotic to think otherwise, but that doesn't stop you guys from running in any time there's a story about laser weapons to suggest "hey, maybe if we hang a disco ball from it."

      Once a warhead is into its reentry phase, your goose is pretty much cooked. You could theoretically stop them with a kinetic kill, but the probability of intercept extremely low. Warheads also tend to be extremely rugged, dense objects (given the Uranium casing and all that), and so aren't a good candidate for LASER weapons.

      Where a LASER really shines (if you'll pardon the pun) is destroying the launcher during the boost phase, or in the case of what's on the USS Ponce, also dealing with cruise missiles and the like. In order to maximize their throw weight (how big of a warhead and/or how far), missiles tend to be built as lightly as possible. During the boost phase of a ballistic missile, all you need to do is weaken its structure enough that the launch forces cause it to fall apart. You don't need to burn a hole through it, you don't need to melt it, you just need to weaken it enough that it buckles under the g-forces. It's a similar thing with the cruise missiles that would be affecting a warship, you just need to compromise them structurally.

      There are some good descriptions how a ballistic missile attack works - I recommend watching one (or reading about it).

      Short version: stopping a ballistic missile is really hard except in the boost phase (when it places the bus in orbit). Attacking the bus before the projectiles separate is extremely hard for many reasons, attacking the projectiles after they have separated is harder still. A practical ballistic missile will have many fake projectiles plus other countermeasures and hitting even one projectile (fake or real) is extremely^2 hard. Overwhelming any reasonable interception system is trivial for any of the large states having ballistic missiles. Which leads to your suggestion:

      Lasers have a short range - air isn't a vacuum. To be able to shoot down incoming projectiles from a MIRV equipped ballistic missile means that there have to be high-flying laser equipped planes in the air. Each of those planes have to have a power source for the laser, one that can be placed into and working at a high-speed, high-altitude airplane. Let's assume that the lives of the pilots and crew is important and remove a lightweight (read: essentially unshielded) nuclear reactor as a power source, even if they are considered expendable having the crew suffer from acute radiation poisoning isn't good if they are to carry out their mission. So what other power source can we have that have enough power density to be usable? Perhaps it'd be possible to use a chemically pumped laser. Much less power density and a lot of practical problems (the waste product being extremely corrosive would be one of those).

      Anyway let's assume we have enough power density to fire the laser and kill a projectile. Hooray! It's just that the missile that delivered that projectile also delivered 9 others. Plus (let's say) 20 decoys. How fast can the laser recharge and kill the rest? If you have looked at a youtube video that is reasonably informative you'll know that the time frame the laser plane can kill projectiles is extremely short. And then there's the problem that a real attack could use multiple missiles targeting the same area making it impossible to stop the attack. As I wrote above overwhelming any reasonable defense is trivial if the missiles are available, that's the reason being MAD is the only sane solution to the problem.

      Laser light is coherent and doesn't follow the inverse square law. A perfect laser would maintain its energy density at any range. Real world lasers suffer from slight incoherence causing it to slowly spread with distance, and from atmospheric absorption.

      Nevertheless, this one shot cost at least $40 million +. The second will result in a cost of $20 million per shot. And, what's the lifetime of the hardware, replacement of end-of-life parts costs and other maintenance costs? It'll take many more than 40 million shots to get down to $1 per shot.

      Typically, costs such as this are analyzed as static and dynamic. So a one-time acquisition cost of $40 million, plus $1 of electricity per shot. That allows you to easily compare to other systems (dunno the acquisition cost of a howitzer-type gun, but I do know the shells cost a few hundred dollars each). A crew of three sounds about the same as a regular small gun (one person to load, one to select and track a target, one to aim and fire), so there's no difference in cost there.

      Moving targets can take a circuitous and rapidly change directions.

    U.S. Troops in S. Korea Can Never Escape Strikes by KPA's Long-range Artillery: Panmunjom Mission

    A spokesman for the Panmunjom Mission of the Korean People's Army (KPA) released a statement on Friday over the recent desperate and undisguised moves of the U.S. to provoke a nuclear war against the DPRK and perpetuate its forces' presence in south Korea.

    The statement said:

    On Tuesday the U.S. imperialist aggressor forces, which moved the Command of their 8th Army present in south Korea to Humphrey Base in Phyongthaek of Kyonggi Province, invited bosses of the south Korean puppet government and military and even human scum including ultra-right conservatives to an "opening ceremony of the new building" of the Command.

    The commander of the 8th Army in his "welcoming speech" praised the south Korean lackeys, terming the move an "event demonstrating the solid south Korea-U.S. alliance" and allowing journalists to look round the interior of the base.

    As far as the transfer of the U.S. 8th Army Command to Phyongthaek is concerned, the U.S. has pushed ahead with it in collusion with the puppet regime since 2003 in order to move its aggressor forces bases in south Korea to the areas south of the River Han to get rid of the striking range of the KPA's long-range artillery strike.

    Lurking behind it is the ulterior design of the U.S. to save its troops only, indifferent to the plight of the south Korean puppet army at stake.

    The U.S. imperialists are busy hyping the transfer of their 8th Army Command, the shock brigade that will play a flagship role in igniting a war against the DPRK. This fully revealed the U.S. scenario to perpetuate its military presence in south Korea and stand in confrontation with the DPRK to the end in league with the south Korean puppet warmongers.

    The U.S. regards the Korean peninsula as a vantage point of strategic importance where the strength of maritime forces and the strength of land forces are interchanging. It is the century-old Asia policy of the U.S. to occupy the whole peninsula with south Korea as its springboard and thus realize its wild ambition for dominating the world.

    It is a tragedy of the U.S. that it is unaware of the tremendous might of the army of the DPRK.

    The bases of the U.S. imperialist aggressors in south Korea, the primary targets of the KPA, can never escape the mercilessly annihilating strikes by its long-range artillery, no matter whether they are located in Phyongthaek or in Pusan.

    The U.S. imperialist warmongers will never escape the miserable destruction if they persist in foolhardy military confrontation moves in south Korea despite the warnings of the KPA.

    The responsibilities of the signatories towards ALL child soldiers, whether they are with the forces of an armed state or otherwise:

    Article 7

    1. States Parties shall cooperate in the implementation of the present Protocol, including in the prevention of any activity contrary thereto and in the rehabilitation and social reintegration of persons who are victims of acts contrary thereto, including through technical cooperation and financial assistance. Such assistance and cooperation will be undertaken in consultation with the States Parties concerned and the relevant international organizations.

    2. States Parties in a position to do so shall provide such assistance through existing multilateral, bilateral or other programmes or, inter alia, through a voluntary fund established in accordance with the rules of the General Assembly.

    The US's obligation was to treat Khadr as a child soldier, not a soldier. And to consider him a victim of acts contrary to the protocol, specifically Article 4.1 on the use of anyone under 18 not recruited as the soldier of a nation, and not to use anyone under 18 in combat.
