Warfare at the Speed of Light

unassimilatible writes "From the They Said It Couldn't Be Done Dept., the Oakland Tribune reports that the Lawrence Livermore Labratory is ensuring that the Pentagon, inside of a decade, could be armed with a beam weapon that is near-instantaneous, gravity-free and truly surgical, focusing to such hair-splitting accuracy that it could avoid civilians while predetonating munitions miles away - perhaps someday even being mounted on Humvees."

      Moreover, all laser guns will, for the forseeable future, remain fair-weather weapons. Airborne particles and vapor diffuse the beam and cut its range enormously. Smart adversaries will attack under cover of smoke or inclement weather.

      "In the first order, lasers are not going to work on bad days," Campbell said. "They're just not."


      Dear Mr. Rumsfield:

      Please schedule all future wars in excellent weather. It's great for the morale of our troops and we get to use our new laser toys.

      Thanks.

    Leaving aside the technical issues of "can you do it," there are the political and moral issues of "should you do it." Precision guided, 100% accuracy is fine until you target the wrong point. The notion that we can have zero collateral damage assumes that we can distinguish between combatants vs. innocents and allies with high accuracy.

    This invention might lower the tragedies of war if we have the intell to discriminate accurately. It might also increase collateral damage/friendly fire if the device inspires overconfidence in those who press the trigger.

    From the article:
    "What we're building," Yamamoto explains, "is a laser weapon."


    And yet it can't be used defensively?
    How about the following quotes?
    "What we're building... Is a laser for cutting through mountians (roads, mines etc.)"
    "What we're building... is a laser to defend our skies, country against missles"
    "What we're building... is a laser to cut underground bunkers on the moon"
    "What we're building... a giant popcorn popper"

    This is kind of sad, when we just exploit technology with weapons in the forefront of our minds and not research or domestic uses! I mean I know they're from the DoD, but with war on their minds, goodness knows what else they're up to.

      Would a gravity-free weapon (even with light) defy General Relativity?

      Gravity is the curving of space-time and light travels through space-time - curved or not.

      If space-time is curved, then light travels a curved path.

      The entire near-instantaneous, gravity-free line is fluff. You can't send a beam faster than light and as long as the beam has momentum (which light does) then it will feel the effects of gravity..

      Will the enemy start using mirrors?

      It depends on the frequency. Regular mirrors work for visible light. Doing optics at other frequencies can be very tricky.

      For instance, your see through microwave door is opaque to the microwaves.

      Come on, is this an article about optics or military equipment? For all conventional intents and purposes, "near-instantaneous" is correct and "gravity-free" almost so. And you know what? In four words, the article has thoroughly described this system's advantages over other weapons.

      Of course, you are probably being facetious and my extreme boredom has driven me to type this reply.

    "... it could avoid civilians while predetonating munitions miles away..."

    So it can avoid civilians who are miles away from the munitions? Even the few dumb bombs dropped on Iraq avoided most citizens in Kuwait...


    I think (that you know) that it means munitions miles away from the LASER could be predetonated (pre- as in before the enemy sends them our way).

    But the real question here is how whether they're implying that the civilians could be detonated too, separately without the munitions, now that we'll have got a big friggin' laser gun...

  15. And bullets don't reflect? by zCyl · · Score: 4, Funny

    you are constantly at risk of the laser beam bouncing back and obliterating you.

    If you stand next to a solid surface, like a tank, and fire a conventional automatic weapon at it, you had better be wearing some serious bullet proof armor.

    The main problem is that any reflecting surface can act as a mirror

    Mirrors do a great job of reflecting low power light. Put a sufficiently high powered pulse laser on the scene, and the behavior of reflective surfaces becomes "non-linear" in the sense that it will simply burn through them.
