I really want to know how they figured out rail erosion. The technology for guidance, capacitors, etc has been there since the 90s but rail life was awful.

If/when they do, the technology/material sciences will be highly secret.

23 mile range for surface bombardment. $500 7# steel slug hitting like a 1000# bomb at Mach 7. The idea is to put it on figures and destroyers for shallower waters for surface support or closer range fucking things up. 

Still a hell of a lot safer than a full magazine of shells if something goes wrong or they take a hit. Then again, fuck if I know what will happen if caps that big pop off.

It's cool to watch the evolution into something resembling a weapon.

But why isn't this Top Secret.  It's almost like the manufacturer wants us to get into a RailGun race.....


And what are they shooting at?     Where's it landing?

Why is there smoke?  Like from gunpowder??

Railguns don't use chemical propellant they use magnets so???

Potentially stupid question. Why is there a cloud of smoke after it fires when it isn't burning propellent?

That was a major selling point - getting the energetics off ships.  Another plus is you basically at least double your magazine capacity because you no longer have to carry separate powder charges.  Safety comes into play because you can't get a round cooking off in a hot gun.  Believe me, a misfire in a hot gun is an asshole puckering event!

A capacitor that big exploding would be "exciting" though...

Neat.

Can someone explain the muzzle report? Is it just a reaction from heat with the atmosphere? I was under the impression an inert slug was accelerated with magnets, so there wouldn't be some chemical reaction on that end.

ETA: Beat by a few minutes.

rail erosion. they're up to hundreds of shots per barrel now and aiming for thousands, so the problem must be fixed.

supposedly it's better rail material plus metallic lubrication.

I was gonna make a big deal out of the tent, and it not being weatherproof and thus too sensitive for naval operations.

Hey this is probably a dumb question but where is all the white smoke coming from?  There is no burning propellant so is it from the heat and friction ?

I imagine it's also the lubricants on the rails causing the smoke.

So, when can I get my man-portable Gauss rifle?

Two questions:

1. How practical is that thing in terms of energy requirements, maintenance, etc.

2. How is it superior to conventional ordnance?

Is it the answer to a Buck Rogers question that really doesn't need answering? I mean, it's cool and all, but isn't it bazillions of dollars when we already have guns?

To answer number 2, you can't jam a bullet.

And if it's going REALLY stupid fast, you can't shoot it down either.

I don't think they've ever shown the gun without the shrouds on it, so you don't see much.  There are a couple of outfits building them, with the 'how' well known.  It's going from 'how' to practical use that's the bastard.  They kinda tend to blow up or eat themselves if not done right.  But that's something you can't tell by looking at the outside.

They've shot at everything from trucks to (I think) 12x foot thick reinforced concrete walls.  Straight shots not lobbed though.

You're looking at probably thousands of amps getting shoved through the system in a tiny tiny fraction of a second.  The smoke and flame is from the heat literally vaporizing part of the rails and a decent chunk of the protective cover on the slug.  So not smoke so much as eleventybillion degree cloud of vaporized metal and plastics flashing off in the air.  At least my understanding of it.

I think they solved the issue with rail erosion by ceramic coating them, but haven't really seen anything to confirm that.  It was a huge issue that they seemingly got past though.  Before it was one shot, replace the rails, one shot, etc because it was destroying them so fast.

They were going to mount it on an Arleigh Burke class last I heard.  Those are powered by 4x 19,570kW turbines, so they make a good amount of power.  The big issue was getting caps to charge fast enough to be usable but not pop on them.  Granted, this is all non .mil stuff I've read, so reality could be way different.  Could have been the Zumwalt too.  Memory is kinda shit these days.
