Watch a Lockheed Martin Laser Destroy a Missile In Flight 177

An anonymous reader writes "As well as providing the equipment necessary to fire missiles, defense contractors also want to offer customers the ability to defend against them. Lockheed Martin is doing just that with its Area Defense Anti-Munitions (ADAM) system. ADAM is a high energy laser system mounted on a trailer allowing it to be transported around quickly to help defend high-value targets. It is still in prototype form, but basically uses a 10-kilowatt fiber laser which can be focused on to a moving target up to 2 kilometers away."

      2KM is kinda useless once the missile has achieved ballistic trajectory.

      At speed of 2.5km/second, the missile will whiz pass this thing quicker than any damage can be done to it.

      Note both the videos show the missile at launch, when they are not at top speed, may work for Hamas to Israel scenario, won't work for North Korea to South Korea type of scenario.

      Sure... but that was implicitly addressed when they discussed the cost of REPEATED use. So this is a Pay (a lot) ONCE, vs a missile (or other ammunition based) system which is Pay (less, but still serious coin) EVERY time you shoot.

      Cost is not a big issue. The big issue is power.

      A laser of this type is almost always a chemical laser because that is one of the best ways to portably produce that much energy in a hurry. The drawbacks of this are
      1) the laser reactant supply needs to be reloaded after every shot or few shots. This is time consuming.
      2) toxic chemical byproducts of the power-generating reaction. If you're defending a base in the middle of the desert, this may not be an issue. If you're defending land that you care about

      • The article refers to a '10-kilowatt fiber laser.' That's means electrical, and probably continuous operation too. 10KW isn't a huge amount of power for something that size. You could run it off of an ordinary engine and generator, though I expect it uses batteries or ultracaps with a generator or external power hookup for charging to avoid keeping an engine spinning all the time.

        Big giants chunks of debris would be no fun, nor would it be if the missile had radioactive material and destroying it turned it into a dirty bomb.

        I'm more curious to know how much of this test was 'real', and how much relied on some of the tricks they've done in the past by essentially making it impossible for it to miss.

        It's not like they haven't stacked these tests in their favor in the past to the point that you'd need whoever might be shooting at you to schedule an appointment and tell you exactly where the missile is coming from. Which kind of defeats the purpose.

          No, that would be the BEST CASE scenario.

          If the missile has radioactive material then:

          1)- It is already a dirty bomb. Destroying it minimizes the damage.
          2)- IT IS A NUKE. Destroying it saves likely a city.

          Neither of these are likely, but you'd rather 1000 dirty bombs than one fissile warhead.

      Considering this a defensive system 2 kilometers means the high velocity threat is nearly on top of what you want to protect.

      Let's say we have a cruise missile traveling at roughly mach 1 or about 1,150 kph - actually pretty slow compared to many missiles. That means that the missile would cover the 2 kilometers in about 6.25 seconds. Better have a hell of a good target tracking system...

      • not all missiles have to reach the ground to deliver their destruction. This seems to be most useful at a distance from the target, in between the suspected launch point and target. Depending on the range of motion, that could nearly double the amount of time to destroy the missile. Like you say, this may require slowish missiles, and a somewhat low trajectory to stay in range. Still, portable tracking, aiming, and power is impressive.

      • Sounds like a point defense system--for when all else fails. The targeting/tracking system need not be limited to the effective range of the laser.
      • by Overzeetop ( 214511 ) on Thursday May 09, 2013 @12:06PM (#43676599) Journal

        A target tracking system for an incoming missile will have a much lower slew rate than the video, where the target is flying perpendicular to the beam. Unless the missile starts doing the Harlem Shake on the way in, it's a sitting duck for a laser adjacent to the target. Also note that the internal tracking system is good to 5km out, so that gives it 10 seconds to lock onto the final trajectory, and it can be tied into a larger tracking system as well.

        This is clearly limited to smaller, slower, less sophisticated munitions right now, but I would anticipate larger power as they get better, which means effectiveness further out and quicker kills. Heck, you don't need any laser research to quadruple the power of this laser - just bring in four of them and target the same incoming vehicle.

        • Uh, a different idea might be to have more than one, spread out. I see no reason why we can't start heating with laser A and continue with laser B. Especially if for any reason scaling them up gets complicated.

        Given the stresses of launch, how long would such a finish remain highly polished, or at least reflective enough to protect against a laser?

        I think you're dealing with a cascade degradation problem anyway. Once a tiny part of the reflective surface loses its reflectivity because the beam melts it, or for whatever reason that can happen, the rocket is done for. There's no problem with laser weapons that can't be solved with the pulse being strong enough and short enough, since you'll never have a 100% reflective surface. Even in experiments with laser-initiated fusion, where the cleanliness and optical properties of the whole system have lab-grade care taken of them, the optical interfaces are a bitch.

        I imagine designers will start to double insulate missiles as well, so that the outer skin can get extremely hot without affecting the inside temperature much.

        • I imagine designers will start to double insulate missiles as well, so that the outer skin can get extremely hot without affecting the inside temperature much.

          Yes, and if the weapon designers decide to send the energy in very short pulses, you end up having to cope with mechanical stresses - the pulse will turn a small amount of the missile surface into plasma which will send a shock wave through the construction. Essentially, this could work like a small HESH warhead.

    • Aluminum is usually the go-to material for broadband reflectance in the visible spectrum. It's about 93% reflective [wikimedia.org] when freshly applied (it corrodes on contact with oxygen to form a thin layer of transparent aluminum oxide which helps protects it from further corrosion but degrades reflectivity - better to coat it with something else). You can improve it a bit with coatings, but those are highly directional. Silver is a bit better for most of the visible spectrum, but falls off quickly towards the blue/

        That would be a 7% absorption in ideal conditions only during initial contact. Once the coating and reflective surface reach a critical temperature then there'd be a cascading failure. The coating would be subject to both ablation and charring, which might actually help the laser more than hurt it.

        There are a lot of factors that would quickly degrade the initial absorption figure (quality of coating, wavelength, surface contaminants, etc...). But even with that, I'd bet that a reflective mechanism would onl

    • Polished chrome varies depending on wavelength. For example a clear plexiglass sheet is opaque to FLIR. On the otherhand an oxidized grey sheet of aluminum plate is a polished mirror at the same wavelength. White aluminum oxide paint may protect it at some wavelengths. Note in the video the targets were painted black. Reflecting 95% instead of absorbing it will require a much higher power LASER.

      This laser with its 1.5km range would be of little use against a maneuverable DF-21D [usni.org] traveling at Mach 10. SM3 is the missile being tapped to for that duty but the kill vehicle is not the big challenge.

      • That *might* be true. Remember that Mach 10 is not the likely speed of the craft at full atmospheric density, and at high speeds the integrity of the heat sheilding is very critical to performance. For an incoming missile, the long range slew rate on the laser will be very low (i.e. easy to acquire and track), and actual penetration of the airframe won't be necessary if the skin is at or near it's thermal limits on final approach to the target.

      It's not quite that simple. If the beam is narrow enough, it won't pass through much rain. If the beam is of the proper wavelength, fog may not deviate it much. Furthermore, there's the little element that the beam will instantly evaporate whatever water it comes close to, so it could very well "buffer" an area around it just by being there. This isn't to say it wouldn't be affected at all, but chances are it could still be effective if calibrated properly.
