Mysterious 'Forcefield' Tested on US Tanks

An anonymous reader writes "Not too long ago General Dynamics announced a successful test of their new Trophy Active Defense System (ADS). The Trophy ADS generates something similar to a force field around one half of a vehicle as a direct reaction to incoming fire. From the article: 'The Threat Detection and Warning subsystem consists of several sensors, including flat-panel radars, placed at strategic locations around the protected vehicle, to provide full hemispherical coverage. Once an incoming threat is detected identified and verified, the Countermeasure Assembly is opened, the countermeasure device is positioned in the direction where it can effectively intercept the threat. Then, it is launched automatically into a ballistic trajectory to intercept the incoming threat at a relatively long distance.'"

    Strange ...

    Ballistic - relating to or characteristic of the motion of objects moving under their own momentum and the force of gravity; "ballistic missile"

    So....... if I keep my enemies at bay by throwing rocks at them, I am protected by a "force field"?

    And the title of the article is MYSTERIOUS force field. The article describes just how the thing works. If you can describe how it works, it's not a mystery.

    Anyway, I'm sick of seeing this stupid story repeated over and over. How many times have I read this in the past two days? Everybody's calling it a force field too. Weird. It's almost like a company has a new product to sell and sent out a press release which was copied by lazy reporters. But that never happens, right?

    It looks more like a point defense system for tanks and other armored vehicles. Very cool, but not as cool as a real force field.

    Still, you've got to admit that this would be a huge psychological deterant. I mean, if I fired RPGs at a tank, and the RPGs (seemingly without cause) pre-detontated before they ever reached the tank, I'd be looking to get the hell out of there and warn all my friends! There would be a lot of "how can fight something like that?" discussions going on that night. :-)

    Defense Update understands that Trophy is design to form a "beam" of fragments, which will intercept any incoming...

    Translation: It's a machine gun. Probably 5.56mm NATO standard, as it's just big enough and the ammo is cheap.

    Basically the same as a scaled down Phalanx.

    Reactive armour has no electronic control, it's just a sheet of explosives sandwiched between two layers of steel held off of the vehicle hull. When a HEAT shell detonates on the surface, the explosive sheet also detonates, disrupting the jet.

    Hate to remind you, but the majority of casualties in Iraq is to Iraqi citizens, largely due to the total absence of security and stability in their country. Casualties in tanks are few in Iraq.

    Oh, absolutely! This is in line with US military doctrine. Create a force so overwhelming it never needs to fight. This is why we have things like Trophy, Land Warrior, and other superiority systems.

  7. Which one is it? by 955301 · · Score: 4, Insightful

    Is it "half of the vehicle" or a "hemisphere of protection"? If it's a hemisphere, I don't expect that they run the protection throught the ground, and if so, that would give full coverable of the vehicle. If it's half, then it's not a hemisphere, because only a quarter of a sphere will protect half of it.

    Maybe this is why people don't like hanging out with me.

    Even if you could fire several RPGs at once just to have one conclude a successful strike, the system is still doing its job by requiring way more resources to take it down. One guy with one RPG taking a tank down is one thing, but having to coordinate half a dozen guys with related weaponry to fire simultaneously is much more difficult to do.

    Not all programmers are peacenik hippies, you know. Even Linux ones.

    I know of several Linux programmers that would probably slaver over the opportunity to program a giant killing machine. (Although perhaps only if it walked and shot lasers and was 50 feet tall. They might not be down with programming an uncool killing machine. I'll have to ask.)

    On a more serious note, do you really think that IBM, HP, Sun, and all the rest of the companies that have paid into and supported this Linux thing would continue to do so if there was such a 'no military use' clause? If you think so, then you have no idea how much of many of those companies revenues come from government contracts, particularly defense ones. Do you think the NSA would help to secure it? I bet even NASA wouldn't touch it. (Most of their contractors who do the majority of the work wouldn't be able to, since a lot of them do a ton of military work on the side.)

    And what is "military use" anyway? Is running a logistics or inventory management system 'military use,' if the inventory being managed is bombs and bullets? What if it's just MREs? What if it's a payroll system for military personnel? How about civilian contractors? Could you use it to run a firewall--if that firewall was in a missile silo?

    Anyone who wanted to make a commercial software product and even had the dimmest hopes of ever selling it to government wouldn't be able to use any code under such a license.
    Not to mention the public-image damage you'd do by associating Linux with yet another political philosophy; as if Free Software isn't controversial enough to sell to management, you want to make sure that there's absolutely no chance that it's taken seriously?

    It would be the best thing in the world for BSD, though...

    Circumstances my friend, circumstances.

    If the US had a bloody dictator who had decided that she didn't like white males with curly blond hair and was committing genocide against them, I would fully support any 'invader' that decided to liberate those like me.

    I would be one of those welcoming them--although I would have likely sought a friendlier country first (if possible).

    If, on the other hand, it was the current gov't of the US being invaded by someone like Saddam Hussein they would find that I was the one taking potshots at them and lobbing home-made napalm cocktails in glass bottles (molotov, too, just to be certain).

    My point is that your comparison is not exactly analogous. Regardless of the validity of many of the stated reasons for invading Iraq (or lack of validity, depending of POV), I don't think that anyone can reasonably deny that Hussein was a bloody butcher of his own people. I remember the news reports of what his sons had been doing. They learned that somewhere, and he certainly could have stopped them. I don't know that going in was the 'correct' solution, but I suspect that any action or non-action taken with regards to Iraq would have led to severe problems. At least something decisive was done, which is a sight more than certain other presidents.

    Holy PR moves Batman!

    My fellow war supporters, here's the situation - all of the reasons we gave for invading Iraq before the war turned out to be hogwash. Whether it was due to lying, incompetence, or (most likely) over-enthusiasm and spin by certain parties best left unmentioned, Iraq posed no signifigant threat to the US in any way. So how do we salvage our dignity? We have to make the war look like a humanitarian effort.

    First - The image of the enemy - we have to make Saddam look as evil as possible. He can't be just another petty dictator, like so many others that we aren't fighting, he has to be Hitler. So give all the grusome details about the evil he's done, but don't put it in perspective to other places, or he won't stand out like we need him to.

    Second - The image of ourselves - we have to make it look like the choice was between waging war and doing nothing - people will always go for a hands-on bad solution over a hands-off good solution. So the fairly effective inspectors and embargos should be dismissed as peacenick-hippie daydreams, and only then can a long, destabalizing war be seen as good. (Especially after our promises of a fast, painless war.)

    Remember the idea we're trying to plant - something had to be done, nobody else had any better ideas, and by golly, we did something. And damn the consquences.
