Defending Against Drones

theodp writes "The US has not had to truly think about its air defense since the Cold War. But as America embraces the use of unmanned aerial vehicles, Newsweek says it's time to consider how our greatest new weapon may come back to bite us. Smaller UAVs' cool, battery-powered engines make them difficult to hit with conventional heat-seeking missiles. And while Patriot missiles can take out UAVs, at $3 million apiece such protection carries a steep price tag, especially if we have to deal with $500 DIY drones."

    I'll bet dollars to doughnuts that I can disable a $500 drone with little less than a portable radio, my laptop and a couple of bucks worth of radioshack equipment. Thing about the drones is that they TOO have weaknesses. And a safe, unbreakable, unhackable, wireless, remote control interface costs a LOT more than $500. And an EM emitter, or even just a remote jamming device, or in case of a wireguided or automated drone a laser to interfere with or destroy the optics seems like pretty easy to come by and cheap solutions.

    And for those really high tech drones that can survive these kinds of odds. I'm sure we can spend a cheap stinger on. Why anyone would WANT to make the leap all the way to a patriot missile, made for smashing down objects the size of a spaceshuttle is beyond me.

      it depends on the drones
      remote controlled DYI drones uses analog video (easy to jam) and FHSS UHF radio signals for control (hard to jam, but not that hard. also crackable to get the control)
      completely independent ones (like the one linked).. i dunno what you're planning, EMP wave?
      they do not need any ground communication. in fact, they one single weakness: they use GPS for orientation. The USA can disable the GPS whenever necessary.
      However some other positioning systems are coming up and its not impossible to make them fly to the right location without GPS control, actually, even without any of the satellite based systems, only using sensors and image analysis (tho those aren't as easy and well known at the DYI ones)

    As US war hero Maj General S.Butler, the most highly decorated Marine by the time of his death (not to mention also single-handedly preventing the closest coup d’état overthrow of a United States President), described US foreign "defense" policy way back in the 1930's:

    I spent 33 years and four months in active military service and during that period I spent most of my time as a high class thug for Big Business, for Wall Street and the bankers. In short, I was a racketeer, a gangster for capitalism. I helped make Mexico and especially Tampico safe for American oil interests in 1914. I helped make Haiti and Cuba a decent place for the National City Bank boys to collect revenues in. I helped in the raping of half a dozen Central American republics for the benefit of Wall Street. I helped purify Nicaragua for the International Banking House of Brown Brothers in 1902-1912. I brought light to the Dominican Republic for the American sugar interests in 1916. I helped make Honduras right for the American fruit companies in 1903. In China in 1927 I helped see to it that Standard Oil went on its way unmolested. Looking back on it, I might have given Al Capone a few hints. The best he could do was to operate his racket in three districts. I operated on three continents.

  3. We're back to WWI by Trailer+Trash · · Score: 4, Interesting

    Read about the history of air warfare during WWI, with the rise of airplanes. The situation is analogous to drones. Ultimately, drones will have defenses and counter-attacks. It's not been a big deal yet because we're fighting people who don't have access to the technology, but that will change.

    Seriously. If we can shoot down mosquitos with optically guided lasers for $50, surely we can shoot down drones?

    Why would you think it would actually be easier for a drone to get through?

    Because you can afford to swarm them. Do you know how much a Tu-95 bomber costs? Divide by $500, and you've got the number of toy flying bombs you might have to contend with instead. If you're spending tens of thousands to shoot each one down you're losing the war even if you're not taking any direct damage from the drones themselves.

    I can think of a zillion things to hit just flying by line of sight.

    You could target oil tankers, hell even oil refineries.

  7. Terror weapon by oh2 · · Score: 4, Interesting

    Consider a small freighter, 200 km off New York. It launches a few hundred small unmanned planes, guided by a small computer autopilot. Each plane carries four thermite stick bombs, similar to the ones used in WWII. When the planes reach the vicinity of New York they climb to a few hundred meters altitude and start dropping the thermite devices. What was cutting edge tech 70 years ago is garage tech today.
