  • Israel's 'Iron Beam' laser weapon may join combat service soon

    From Fred Bloggs@21:1/5 to All on Mon Oct 16 04:52:18 2023
    The system is designed to destroy short-range projectiles too close for the Iron Dome system to intercept effectively.

    It should be good for drones too, taking a cue from Ukraine where they're proving to be very disruptive. Drones are moving slow enough to get adequate dwell time out of the laser. IIRC the system, which has been in development for a while, was originally
    designed as an anti-drone air defense ADAD. Drawback is they need a system at each and every area they want to defend, which could add up to being a lot.

    They need something like that. Hamas fired 5000 cheap rockets into
    Israel and claimed to have 100K more available. No smart kinetic
    weapons will ever be available to intercept a huge number of dumb
    rockets. Even a laser defense can be overwhelmed by thousands of
    rockets, all a few seconds out.

    But offense against defending lasers shouldn't be difficult. Make lots
    of shiny rockets and shells. Have any laser defense systems actually
    worked?

    Interesting that Hamas used suicide pilots in motorized hang gliders,
    and not drones.

    Some iman said that western religions are the religions of life, and
    Islam is the religion of death.

    Israel has that Tamir interceptor for the small stuff. It's not cheap for the system but IIRC the interceptor is 50k$:

    https://en.wikipedia.org/wiki/Iron_Dome

    Patriot is out of the question at $$$ millions per missile.

    Even a laser defense can be overwhelmed by thousands of
    rockets, all a few seconds out.

    There are things they can do to extend the reaction time. Like detect the launch and not wait for a surveillance radar of lidar to pick it up. Problem with those dumb Qassam things HAMAS uses is just that, they're dumb projectiles, so they need to be
    damaged enough by the laser to destabilize their flight. That spells a very powerful laser.


    But offense against defending lasers shouldn't be difficult. Make lots
    of shiny rockets and shells. Have any laser defense systems actually
    worked?

    They do have a demonstrated capability of taking down drones at long range with their laser.

    Maybe Alibaba doesn't sell them.

    Islam in this context is just a spiel they use to attract low IQ dupes into the fold. The religion proper is based on Judaism, Christian and some other beliefs ( far eastern?).

    Bit or Reagan starwars perhaps...
    quote:
    "According to the company, the naval version will take 4 to 5 years to reach active availability."
    Slow drones could use some reflective materials as protection.

    It may be easier to attack the drone electronics with microwave beams and also jam their GPS (send fake GPS) and
    jam their communication frequencies.
    That technology exists.

    Oh, not so fast; shiny things are usually metal, and metals obey Ohm's law; reflection is a consequence of mirror currents in the metal.

    Get the currents high enough, and Ohm's law guarantees heating. Missile becomes hot gas
    on "this end toward enemy".
