Navy tests new electromagnetic railgun that can fire projectiles from ships at 4,500mph

The Navy have developed a weapon that will use a ship's self-generated power to fire at long-range targets.
This means that the electromagnetic railgun launcher uses electricity instead of chemical propellants.
Magnetic fields created by high electrical currents accelerate a sliding metal conductor, or armature, between two rails to launch projectiles at 4,500mph.
The railgun is powered by electricity that has been generated by the ship and stored in a 'pulse power system'.
Next, an electric pulse is sent to the railgun, creating an electromagnetic force accelerating the projectile up to Mach 6.

Popular Mechanics has speculated that the railgun might end up being installed on board one of the three ships in the Zumwalt class, the experimental super-destroyer with a power plant strong enough to operate the weapon. The recently commissioned USS Zumwalt has been experiencing difficulties with its 155mm Advanced Gun Systems, designed around the projectiles that cost around $800,000 apiece.

Thats awesome but why would there be fire and smoke?

They haven't shown what it does to a target at distance. Until then I'm not impressed.

This has been in development for a long time. Glad to see it actually get used -and (gasp) possibly save the Navy money.

a projectile going mach 6 would be terrifying. Wonder what the rounds per minute is.
ETA: this is a 155mm shell for reference.

What is this projectile made of? I hope they zero in on the target fairly quickly when they sight it in.

Thought it was a simple question, if no propellants used.

In WWII the Germans had a rail gun that would go 2 mph.

4,500mph.

this isn't going to happen in any real numbers for a long, long time.

More than a mile in one second.

talk about needing to use this strictly on high value targets

Why in the hell are they they expensive? It could just be a regular ol 16" shell. I imagine those are highly conductive.

I would imagine that it's the R&D behind the thing more so than the actual materials.

Projectile cost seems high? The railgun should be saving money.

Anything moving that fast would probably have enough friction with the air to create some form of fire. Like when the shuttle reenters the atmosphere. The cloud of smoke is probably water in the air turned to water vapor. (IMHO)

I'd imagine the projectile would have to be of a strong enough material to maintain structural integrity going that fast and absorbing that much initial force.
