Keep thinking

Danger Room reports on a DHS initiative to place a laser-equipped UAV 60,000 feet above airports in the national airspace structure as a way of blinding terrorist launched MANPADS. Which would probably be a more cost-effective way of defending against that particular threat than equipping all domestic airliners with flare dispensers linked to a passive missile warning system. Never mind your false alarm rate, or the risks of popping off magnesium incendiary devices over densely populated neighborhoods.

That is, it would be a more cost-effective system so long as we can be sure there aren’t any clouds between the UAV and the missile’s sensor.

    …and Seattle year-round? :D

    Details…details…details…

    bet it takes eleventy billion dollars to make that observation.

    To my knowledge, we don’t have that wiz-bang flying over Baghdad yet. Sounds pork-a-licious to me.

    With the right gear, that could mean a good, high res LIDAR over cities. Great for traffic enforcement.

    We just need to put F-22s over all our major cities. It knows when you’ve been good or bad…

    Actually DHS is testing laser based self protection systems on some aircraft, including some FedX jets.

    They seem to work wel, though expensive.

    Biggest issue I have with the concept of the UAV is timelines and getting energy into the seekers from off-axis. The latter would be a big issue in my view.

  • Well there are several types of lasers many do not work under 3,000 feet well, so if this system uses Argon Laser for instance it could hit certain targets at certain altitudes and if it uses something else and was that high Flight Level 60 then it could not. So, it would not be too much of a problem or help much with ground targets, but it would be very wise for air-targets.

    Now then, if it had capability of decending below 3,000 feet or the elevation was higher than 3000 AGL then it could do both ground and air targets from 60,000 ft. It’s a good idea really and if it were a dirigible, it could stay up there for years and some of the gas in the blimp could be used for keeping it aloft, thus it would be pretty safe, and at that altitude no airliners (currently) would run into it.

    I think the idea is worthy actually.

    It’s not so much the lasers – although the way I understand it, they have trouble punching through clouds – but the targeting system will definitely have a problem looking through the inevitable undercast to see an IR missile launch.

    Fair weather friends.

    MANPADS vs. big multi-engines are over-rated.

    2 engine DHL cargo bird out of Iraq- survived
    C-17 out of Iraq- survived
    C-5 out of Iraq- survived

    Yeah they are dangerous. And I would worry more about smaller aircraft.

    ELP- I have the powerpoint from DHL about that flight. Used it as a case study in aircraft stability and control, then again in stealth and survivability. They survived that hit and flew admirably. . .but I wouldn’t count on that kind of resolution every time.

  • Quick question(s) (I’m OUTCONUS and Japanese keyboards are immensely difficult to type on, I’ve no idea how Skippy does it) for everyone:

    Given that:
    1. The system would have a prolonged dwell at FL600 (I’m imagining some manner of tether).
    2. You would need to confuse and blind a MANPAD sensor at close to ground level almost immediately after launch.

    Question:
    1. Blindness? Not on the part of the missile sensor, but if you’re doing what you’re (please forgive me for being intentionally vague and then getting myself into some sort of trouble) doing at that power level, you’re going to blind some poor schmoe on the ground.

    2. What happens when the mooring line parts? (I’d like to refer everyone to the scene in ‘Hope and Glory’ where the blitz baloon breaks loose.)

    3. FAR Part 91 students on solo, anyone?

    3.a. Light civil folks not paying attention to detail? (I remember a conversation between LAX Approach and a rather lost Cessna 172 who, after some prompting “acknowledged” that he was IFR certified and knew better than to be in that area at that time.)

    By the way: I understand that there are government foax that read this here discourse. If you’re in the mood for spendin’ some dough and don’t know what type of target to throw it at, I sure could use a Mamiya 645ZD and some decent glass for said. I’ll take purty pictures with it and everything. Maybe send you some. I’d need a paltry $40,000 (USD) to pay for the works. E-mail me and I’ll tell you where to send the cashier’s (no personal, no credit, cash is okay, Euros or Yen preferred,) check.

  • When using a Japanese key board just remember that many of the shift key functions are different. So long as Romanji is selected its not too hard.

    It’ll never work. Everyone knows that the spate of recent tornado activity and resulting cloud cover are all George W. Bush’s fault. If he had signed the Kyoto treaty then global warming would be on the retreat and we would all be enjoying clean, cloud-free skies.
