COME ON GUYS LETS HAVE A HARCORE SCIENCE THREAD! YEAH!

During a test of the effects of Kinetic Energy Weapons (KEW) at the General Motors-Delco test facility, a seven gram Lexan projectile was fired from a light gas gun at a velocity of 23,000 feet per second at this cast aluminum block. The KEW technologies are part of the Strategic Defense Initiative research program to determine the feasibility of implementing a multi-layered defense against ballistic missiles.

Have you got a picture of the projectile?

This thread screams SCIENCE!!!

A small projectile has 32000 feet? That's a lot of feet. And legs. But presumably all those legs make it go fast?

question is, how does a guass gun fire a nonmagnetic object? did it have a magnetic sabot? was there a magnetic ram behind it?

OP says light gas gun, not gauss gun.
In essence, it's a giant air rifle.

Take a look at the pic again. It's right there (I assume)

Looks like it, but I highly doubt the shape is correct.

those sort of tests are carried out in vacuum, so with no air resistance, a cylindrical shape is just dandy.

fun fact: the kinetic energy of the projectile is equivalent to that of a 200lb man falling at 131 mph, a tad under terminal velocity, though in the case of OP's pic, the energy is imparted over a very small surface area.

even though that does sound emmensly fast... im not impressed by the hole it made really...

Air cannon in vacuum? Interesting! If there's only a small distance between the barrel and target it wouldn't matter too much. After all the projectile might not even be outside the air cannon's air pressure muzzle blast wave by the time it hit.

That's fast.

Why is this useful only for anti-air?

You could fire such a thing at a human target and you don't even have to hit it, as only the velocity will kill hte human even if it flies like 15 feet away.

kenetic weapons are a nice idea, you dont need explosives... but, you do need some method of accelerating the projectile. railgun's are the current fashion, the (shown above) dread is a centripital force device that spins metal balls and releases them in a devastative volley. the problem with the railgun, even on a nuke ship they will suck down every bit of power on the ship and still want more, the dread takes ages to spin up and it has to stay spun up to be ready to use... more electricity, so they want to transfer all their weps from explosives (an ak can reputedly be dunked underwater and still be useful) to battery powered weps. the ones being considered for satellites may require (illegal) nuclear power plants or some demi-illegal radioactive battery, essentially we might go to kenetic but it just means electric.

No they wont. I did the calculations in an earlier thread, and if you devoted just one of the gas engines on a modern US destroyer to powering a 64 mega joule rail gun you could fire it once every few seconds, perhaps as slow as 10 seconds between shots if you have terrible transmission efficiency.
>> feasability Anonymous
Since it is missle defence, the weight of the projectile is extremely important. Think rockets carrying 100 of these things, its like a giant space shotgun. (technical term) I would say this is a succesful test.
oh and the projectile is pictured in the middle of the hole.
I would like to know what kind of Al that is though. pure or alloyed?

dod pipe dreams are all about infeasible weapons systems, theres huge money in it, as for feasible wepsys uhh... even our old shit is trump

btw Lexan is what they make iPod and iBook cases out of.

But the point of my post was that is isn't infeasible, even with our current destroyers. One of them contains four generators of the size required.
