Metal storm is kind of lame actually. Shoots really fast - reloads really slow.

Interesting. Sounds like an effective tool to take out enemy planes, maybe missiles, and line-of-site surface targets not obscured by the horizon, but I wonder what the arc over its effective range would be. Eg, can it hit over-the-horizon targets, or does it shoot too far in a straight line so the projectile just flies harmlessly over their heads (from 500ft above the surface, the horizon is only ~32 miles away, much less than the 250 mile range)? Also, since the projectile appears to be only a metal slug and doesn't carry any explosives, what is its minimum speed to cause significant damage, and what is the maximum elevation at which it can be fired and still have that minimum speed when it returns to the ground to hit its target? I'm sure they've got all this figured out already, but I'd be interested to see their ballistics calculations.
Um, how do you propose to hit a plane with a cannon?
It's enough of a challenge to do it with lasers and they - for all intents and purposes - go in perfectly straight lines and hit instantly.

Right... anti-air artillery is SUCH a novel concept...
The 40mm Bofors on the ship I served on could blow a 2m "sausage" out of the sky on a consistent basis. And those do only about 1km/s muzzle velocity.
That's not much of a challenge, actually, given enough altitude and contrast. There are a number of visual tracking systems already since the 70's at least, it was a backup to radar tracking for instance on the ship I served on.
The cameras that follow the spaceshuttle launches for instance can track it at _very_ far ranges and very high altitude.
Well it's the same(more or less) gun as the AlliedAA in BF1942, actually.

Talking about guns on ships?

now thats what I call a gun
These things make such a lovely sound when firing (from a distance of course) kind of like a buzzing bee. Crazy thing can munch through its mag of 1500 rounds in 20 seconds. Ands its fully automatic from aiming to firing Guden.
Agree about the Metal Storm though, and I would expect the first shots fired would be less accurate and less powerful. Hmm, wonder if under a fast rate of fire the later rounds could catch the first ones up?
Interesting about that rail gun though, to accelerate something from 0 to 13,500 mph in 0.2s, wouldnt that need like a 500m barrel?

But why would you want to reload ?
If you assume the projectile was , say, a 1kg mass, then 13000mph=> 5813m/s so at the start it'd have ~16M joules of energyfbg1 said:
According to one site,
(Bah! why can't they do everything in metric... bet it's a bloody yank site
)so that's about 3.7 MJoules/kilo.
Looks like that would be the same as about 4kg of dynamite (assuming an insignificant amount of drag).

Right, but AA shells are of the fragmenting variety. These are straight kinetic projectiles, and unless the caliber is rather substantial all that's going to happen if they hit a plane is they punch a small round hole straight through the 1-2mm aluminium-skinned airframe and the bullet continues merrily on its way, assuming it didn't strike some sort of vital component inside or one of the fuel tanks.
Was that a supersonic sausage flying at stratosphere altitude by any chance? Somehow I can't envision that to be the case.
Strange then that most of the US missile defense shield tests have been such spectacular failures so far. Same with the "patriot" weapon system, I might add...

They've found that the best way to shoot down missiles, even those at supersonic speeds is simply to get as much metal in the air as possible. That's why the likes of phalanx is deployed on ships with as accurate targeting as possible, but primarily to put as much ordinance as possible into the path of the missile. Same with airplanes.
Heck, a relatively soft and slow seagull hitting the canopy or being sucked into the engine intake can take out a plane, what do you think thousands of rounds of hot metal going at hundreds of miles an hour are going to do as they go though the airframe?

Zabag,
According to what I've read, it's actually not that easy to hit airplanes with gatling cannons for a variety of reasons (limited range is a major one), and even the phalanx missile ship defense system is considered fairly ineffective and is destined for replacement.
Furthermore, if it's one thing a railgun can NOT be said to do, it's to put a lot of metal in the air simultaneously. With the firing rates proposed (what was it, 1 round every 10 seconds?), it's more like taking potshots at an airplane as it wooshes by.

It's been in production since 1978, so I'm not surprised it's due for replacement. 4500 rounds per minute or tungsten and depleted uranium isn't slow.
