Electromagnetic Railgun: An Innovative Naval Program

Electromagnetic Railgun:

An Innovative Naval Program

What is the electromagnetic railgun? In a word, innovation. This weapons system will bypass the traditional use of chemical propellants or rocket motors for firing projectiles or missiles. Instead, electromagnetic railguns mounted on U.S. naval vessels will use electricity to launch projectiles farther and faster than any ship in today's fleet. When fully operational, the electromagnetic railgun (EMRG) will:

Because of its design, EMRG uses electrical energy to deliver a time-critical strike rather than the chemical agents in warheads and propellants that can place crews and ships in jeopardy. EMRG represents significant advances in Navy and Marine Corps capabilities, extends the range of Marine Corps combat capability and distributed operations, and improves safety aboard sea vessels. The electromagnetic railgun is just one more leap-ahead technology catapulted by scientists at the Office of Naval Research.

A Historic Railgun Moment
The Office of Naval Research made history Jan. 31, 2008, with the muzzle velocity of its electromagnetic railgun at the Naval Surface Warfare Center Dahlgren Division. Fired at 2,520 meters per second, the shot generated 10.64mj of muzzle energy.

I still can't get over the fact that the projectile can travel 200 miles and still hit the target going Mach 5. Yikes! Welcome to the future!

The problems with this are heat, power required, and recharge. It is not ready yet.

A lot of potential in that weapon system if the can get it developed to use on a ship.

Its a wonder the rounds dont burn up from heat at those speeds.

The future? This is an old ongoing project and the article is likely a pitch to make it current to keep Hussein from cutting it from the budget.

You need to watch discover TV more, the work on these things has been going on for years. The discovery demosrtations a couple of years back were something.

It would require atleast 1.21 Gigawatts and a flux capacitor.

and to think I was once impressed by “Dora” the German 800mm
railway gun which had a range of about 23 miles.

The mission of the Dosthra remains unclear. The most curious thing about this aircraft was that it was armed with a weapon called “Metallstrahl”. Metallstrahl was a type of rail gun that used magnetic forces to attract and repel steel bullets and launch them at tremendous velocity.

Whether or not a rail gun was actually mounted in this aircraft or not, it is a fact that such a weapon was under development by the Germans in this time frame.

Hilter was working on it:http://discaircraft.greyfalcon.us/DOSTHRA.htm

There’s also reliability - being able to do multiple shots. There’s enormous pressure on the gun to break apart.

It’s a viable technology but it’s not going to be in the field for a long time.

The Flux capacitor has always been the problem.

LOL,

Its a wonder the rounds dont burn up from heat at those speeds.

The SR-71 spy plane(Also known as the blackbird)officially flew at Mach 3.5, but I've heard people speculate that they flew as fast as Mach 5, and it heated up to it was red hot and even expanded a few feet while doing this in the air and it was made of Titanium. So if they made the projectile out of Titanium or something harder I can see them going that fast.

As far as hitting something that far away and being on target I can't see that being done, but who knows with computers, and the right elevation at that speed who knows you just might hit the target. And I doubt if wind is much of a factor.

Would anybody know how fast the fastest rifle bullet goes in terms of Mach speed.

As far as I know, the fastest production rifle bullet is the .220 Swift, which reaches 4000 feet/second.

Experimental "rifles" (some are smoothbore to reduce friction from the rifling), have reached 5000 fps, sometimes a bit more.

The absolute limit is sonic velocity in the propellant gas.

A light gas gun typically uses hydrogen as the propellant gas and can reach mach 16. The hydrogen is compressed by firing a piston in a traditional naval rifle, and then using the piston to compress the hydrogen. These are laboratory items, and are not suitable for field use.

Because they do not use propellant gases, light rail guns do not have this limitation and can reach much greater velocity.

There’s another big problem: shooting at anything with anything from 200 miles away is only good against motionless targets. The Iowa class ships never had that problem for some reason....

Pull the Iowa class battleships out of mothballs, refit them with nuclear reactors, replace the 16” guns with EMRG’s and GO TO TOWN! By using large banks of capacitors to store energy that can be discharged quickly, the power plant can be run at near max capacity to recharge them quickly.

I believe the material of choice is tungsten.
