US Successfully Tests Self-Steering Bullets 216

Posted by Soulskill from the bad-news-for-Neo dept.
mpicpp sends this report from The Independent: The United States Department of Defense has carried out what it says is its most successful test yet of a bullet that can steer itself towards moving targets. Experienced testers have used the technology to hit targets that were actively evading the shot, and even novices that were using the system for the first time were able to hit moving targets. The project, which is known as Extreme Accuracy Tasked Ordnance weapon, or Exacto, is being made for the American government's military research agency, DARPA. It is thought to use small fins that shoot out of the bullet and re-direct its path, but the U.S. has not disclosed how it works. Technology in the bullet allows it to compensate for weather and wind, as well as the movement of people it is being fired at, and curve itself in the air as it heads towards its target.

Also you can make the rounds sub sonic, so they don't make that loud crack sound from the sonic boom without reducing accuracy. Note that this will require the shooter to remain sighted on the target until the round hits, in order to guide the bullet to target, as there is no practical way to put long range sensors in a bullet.

          This instantly reminded me of an 80's movie called Runaway with Tom Selleck, who is a part of a special task force to hunt down and destroy malfunctioning "runaway" robots.

          Their handguns could lock on a target and program the bullets just before firing to stay on their target, although they looked more like miniature rocket based missiles with their own tiny engines and guidance fins.

          I remember a number of the larger scenes giving a bullet-point-of-view type thing as the target goes running away and try to evade the shots by going around corners and obstacles, even purposely missing other people, before embedding into their target and exploding.

    • Only problem is that you need a 'spotter' to do so. The current system uses a 'real-time optical guidance system help track and direct projectiles.' This means that the guidance system has to be able to see the bullet so it can send corrective commands to the bullet. So in order to shoot around corners, you'd need a 'spotter' with the guidance system with a view of what's around the corner.

      How can you not be "self directed" if you are compensating for "movement of the target". It has been given a target and actively modifying its flight profile in flight. There must be some intelligence and/or sensing and/or feedback to do this. Seems like an exercise in semantics to call it not-self-directed (at least in flight).

      Is this a disclaimer to avoid getting these bullets confused with things like autonomous killbots? Though it is pretty easy to assume killbots will overwhelming choose these bullets as ammo :-)

      • The same way laser-guided bombs aren't self-directed. I'm guessing here that the gun puts an IR laser dot on the target and the bullet homes in on that. Keep the dot on target and you should hit.

        • With these the guiding laser could be included in the sniper scope. Just keep the target in your scope until the target is destroyed.
          Lase guided bombs require a plane to drop the bomb. With this the sniper can do everything himself.

        Probably not much. It's one reason why they still teach hand-to-hand combat: technology can break. A sniper still would need to learn how to stalk, recon an objective/target, and hit something at a very long range (which includes computing the shot).

      yeah, pretty much this. Fins wouldn't work well because they'd have to readjust their position constantly as the bullet rotates. Considering the speed at which they rotate, it'd make much more sense to just mess with the internal weight distribution of the bullet.

      • The summary mentioned that these are shot from a "smooth bore" rifle. Meaning no twisted landing to make the bullet spin, like a shotgun. So unknown from the info given if the bullet even does spin. The reason most bullets spin are to keep it stable in flight so it doesn't start tumbling. *IF* it used fins somehow, I'm sure that is what would keep it stable in flight instead.

    • More likely they slightly adjust the centre of gravity while the bullet is rotating. Adjusting the mass internally would be simpler and more reliable then fins.

      IIRC most of our military rounds are intentionally weighted off center so they tumble after hitting a target instead of leaving a straight exit wound. I'm thinking these things might just be bullets with fins and springs to keep the flight path straight. You'd be amazed how much a little wind can affect a bullet at 100 or 200 yards, let alone long distance shots, when you consider how short the duration of their flight is and how much kinetic energy they have in such a dense object.

      • The mass could be moved forward and back without changing the direction of the bullet - so long as the bullet is rotating. If it stops rotating, say by hitting an object, then it would absolutely start to tumble. But I was referring to moving the mass perpendicular to that. Basically a pendulum inside the bullet. This would result in the bullet tumbling right away if not controlled. But if controlled, could be used to direct the bullet - at least in theory.
      • While in the Marines I had to take regular rifle qualification tests. One year I was in Okinawa for the test and the weather was crazy that day. There are wind flags on the range that are supposed to help you adjust. For the 500 yard shots there are three flags between you and the target. On that day they were all blowing in different directions, which I could have dealt with, but they also kept changing directions.

      This is the most information I could find. Maybe someone else can do better:

      Design and Demonstration of a Guided Bullet for Extreme Precision Engagement of Targets at Long Range Performing for the DARPA Extreme Accuracy Tasked Ordnance (EXACTO) program, the team developed a revolutionary .50 caliber bullet guidance system that will be used to produce the smallest, fastest, highest g projectile to date that is fully guided. To perform across a 70,000-g launch acceleration, they designed a first-of-a-kind, two-body bullet with a decoupled aft section that despins from 120,000 to 0 rpm in under 300 ms. This required the implementation of an innovative, alternator controlled, despun aft section that provides sufficient maneuverability but low drag for the bullet to remain supersonic out to maximum range.
      The team worked within an 11-month time frame to deliver a system that exceeded all of the accuracy requirements across a variety of night- and daytime ranges, moving targets, wind speeds and directions, and other environmental conditions. The effort culminated in May with a physics and experimentally-based, fully integrated hardware- and software-in-the-loop demonstration that not only validated superior system performance, but also exceeded designated product requirements over all ranges and all target motion challenges. For this accomplishment, the program was recently awarded Phase II to continue the design and development of the guidance mechanics and electronics in collaboration with a commercial sponsor. The outstanding technical achievements demonstrated in the design, fabrication, simulation, and testing of this miniaturized guidance system are well-deserving of this award.

      There's also a picture of a model that differs from those that appear in most other press releases.

      From what I could find out, it looks like Draper Laboratories does the Guidance, Navigation, and Control (the interesting part), Teledyne does the optical target acquisition/locking (semi interesting), and Orbital ATK makes the ammunition part -- probably primer, charge, casing, and shell.

There are a few narrow applications where naval bombardment would still be the optimum choice, amphibious landing support for example, but those cases can generally be dealt with using a combination of other weapons. Don't get me wrong, main gun fire kicks ass, but it's just not as useful as it used to be for ship to ship combat.
      • Ship to ship combat is a thing of the past, excluding sub vs sub or patrol boat vs patrol boat. Big guns are for raining cheap and efficient death along the shoreline and 25 miles inland. Should at least have big guns on ships like the Wasp and America.

It's easier to just make use of missile cruisers and air strikes to fill the same role. As a former Marine, yeah I'd prefer naval gunfire, but that's just not an efficient choice for the navy.
