A space-age "force field" capable of protecting armoured vehicles and tanks by repelling incoming fire is being developed by British military scientists.

This is pretty damn cool.

I hope it isnt as bad as the plasma shield the US air force developed for thier sattelites

on the side note the bullet deflection magnet idea is awsome preventing direct impacts.

it seems to merely produce a magnetic field by dumping energy into the armor... I mean sure, its new tech, but its nowhere near star trek yet. Maybe soon when we can project the field better, but .. not yet

Enterprise had something called "polarised hull plating". Which is essentially what this stuff is.

Also, since this force field thingy makes an extremely short lived, but powerful magnetic field it is an in-built ECM too, like a weak explosively pumped flux compression generator. The technology should have alot of other uses too, the ability to dump alot of energy in a very short time into a mag. field should be useful for that US railgun project for example.

The energy required to make a strong enough EM field to repel a fast moving massive object is going to be a lot more than a tank could likely produce.

Seems more likely some smart scientist had an idea and is doing some research into the subject. Then someone in the media heard about it, started foaming at the mouth and flailing about wildly while screaming "STAR TREK" repeatedly and writing an article about it. The article mentions "bullets and shrapnel" which are hardly a threat to a tank. Seems likely that a rocket propelled grenade or a heavy anti-tank shell moving at hundreds of miles per hour is less likely to be deflected and more likely to go "lol electromagnetic what?" before impacting the tank with a very small change of course that won't effect much.

Of course I could be wrong. But I'd love to know where a tank is going to get the energy to do this. Being able to store lots of energy doesn't explain where it's going to get that energy from. Though regardless, this is nothing at all like a "shield" as seen in traditional sci-fi.

Quote:
When a threat from incoming fire is detected by the vehicle, the energy stored in the supercapacitor can be rapidly dumped onto the metal plating on the outside of the vehicle, producing a strong electromagnetic field. Scientists behind the project claim this would produce a momentary "force field" capable of repelling the incoming rounds and projectiles.

Although it would last for only a fraction of a second, if timed correctly it could prevent rocket propelled grenades, which detonate on impact, from reaching their target. The supercapacitor could then be rapidly recharged ready for another attack. The idea is similar to the force fields portrayed in science fiction movies which produce an invisible protective shell around a vehicle or object.


Quote:
He said: "The supercapacitor material can be charged up and then discharged in one powerful event to repel incoming fire. "You would think this would require huge amounts of energy, but we have found it can be done with surprisingly small amounts of electrical power.

The article semi-explains this as a quick-stop reflect-barrier, not a continuous running shield, but as said, the thing is still in development and is subject to change/cuts/cancellation.

Interesting idea. However such a system would really need to augment existing armour rather than replace it. It's all well and good having some fancy mechanism that defeats shaped charges and projectiles but you'd then come up short against blast effects and the like.

This. Star Trek shields are pure fiction, but this idea has the potential to do two things:

1) Set off the fuse on incoming missiles. A contact-fused RPG is going to explode when you give it a nice hard smack that makes it think it just hit the tank. Detonating short of the target severely reduces the armor penetration.


2) Damage/deflect incoming solid shots. It's the same general principle as reactive armor, you don't 100% stop the projectile, you just disrupt it enough that it can't penetrate your armor effectively. For example, anti-armor tank shells use a long rod to focus as much force as possible on a small area of armor. Hit it off-center away from the tank, and by the time it hits your armor it is tipped sideways slightly and everything is no longer concentrated on the same point of your armor. End result: you still get hit, but none of the delicate bits inside the tank get damaged.

My biggest question is where this energy comes from, which isn't explained. Being able to store energy is great and superconductive armor is awesome, but you still need to be able to get a charge from somewhere. Of course the engine itself can be used to charge the capacitor, but how much energy are we talking about?

"Relatively" small doesn't really say anything at all.

Intersting how simple such an effective system is. My only question is what are they gonna make now to counter/kill tanks with this system fitted onto it.

hmmm.... making a field that can decelerate a projectile to speed where plating can simply make it bounce off, instead pretty much stop the projectile, seems to be the right choice due to technical limitations. think of the EM field as an armor hardener instead of a proper shieldRazz

good thing about this tech is that it will probably mean less armor plating, meaning lighter vehicles, OR increased survivability of current plating.


it might also mean that we will probably start to see ceramic-based composite projectiles to counter it.

The technology behind this has been shown on documentaries and there are several articles on the internet, it seems that the idea behind it is to reduce the weight and thickness of armour on IFVs and APCs rather than for use on main battle tanks. Vehicles like the Striker and Warrior are very vulnerable to high calibre armour piercing rounds and man portable shaped charge warheads (RPGs, Milans etc) and being able to protect those kind of vehicles without masses of composite armour and additional jury rigged external structure would be a huge improvement over the current light armour technology.

Unless they can get the armor to last more then a fraction of a second this is never going to work. How would the tank be able to activate the armor at the exact moment the RPG hits?

And beyond that, I have doubts such armor could stop an anti-tank projectile.

it really depends. increasing survivability by 1% is still a massive increase. And as Tyran said, I can see this actually be of more use on light vehicles than MBT's.

decreasing the armor weight would mean even more mobile vehicles, thus increasing survivability by a good margin.

a lightly armored buggy armed with TOW's and Hellfires making circles around a tank without it's turret being able to keep up for example.

Given that the entire point is that the technology is being designed to do precisely those things, I suspect you'd be surprised.

Sounds more like a point defense system like in Homeworld than Star Trek egg style shields. As someone has said, the Star Trek shields don't make much sense from our current understandings of science.

I imagine spaceships in the future having this kind of electromagnetic plating, heavy armour and flak screening rather than 'shields'.


btw how expensive is an EMP weapon? Surely this system cannot replace armour as it cannot be hard to disable?

complements, not replaces.

I can see it being overwhelmed by either non-metalic projectiles (ceramic polymer projectiles?), EM blasts (nukes at close range?), or simple saturation tactics.
