    Navy test of the BAE-developed electric rail-gun planned for deployment on the new DDG-1000 Zumwalt-class destroyer.

    This supergun is designed to fire a 40-pound projectile at 4,500 to 5,500 miles per hour using electrical impulse energy rather than gunpowder.

    So, what's with the fire?

    The projectile's friction was probably ionizing the particles as it passed through the wall.

    Was it just me, or did it look wobbly as it was flying through the air?

    My hypothesis would be super heated plasma from the energy dump used to push 40lbs of projectile from 0 to over 4500mph in like really quick time.

    It's a .10 mm, right?

    You have to admit the 'Grandma font' type in the second video looks idiotic - Cold War meets computer noob.

    Other than that, I'm happy to see this progressing. It'll probably be used on me one day.:rofl:

    I thought they canceled the railgun project?

    Navy wants it, Congress not so much. Armed Services Committee tried to kill it but the project is still alive. They got a couple prototypes for testing earlier this year. It will be 7-8 more years, if ever, before they could have anything operational. Seems to me in the current budget climate it looks shakey.

    The videos posted are almost a year old.


    Not sure about the project though. I hope it is still in place as I find it really cool.

    Some Thoughts On This...

    I've read that a variation of this technology could conceivably launch spacecraft. Of course, the equipment and payload would have to survive the violence of the launch cycle, though.

    Don't the newest aircraft carriers, and some of the older retrofits use an EM catapult these days?

    This kind of weapon would be especially vulnerable to an EMP attack, wouldn't it?

    Not much to work with if you handload.

    The only drawback is it doesn't work on cloudy days.

    Awesome weapon system,I'm curious to the cost advantage vs disadvantage.

    Well I don't know about the weapon system, but the unit cost for the ship they want to put it on, Zumwalt Class Destroyer, is said to be 3X the unit cost of a B2 Stealth Bomber and climbing. Plus as costs continued to escalate during the project they downsized the number of ships and capabilities of each ship.

    In the long run it will take up less space and you can store more ammo, since you wont need any powder or propellent, which normally takes up a ton of storage space. You will also have longer range and better accuracy.
    Of course there are 2 big downsides to it at this current time. The cost is Very high, and the power requirement is pretty crazy and not compact in size at all.
