    Yes, Yoma4, we do need more guns. Guns are cool. Blowing stuff up is cool, too. I don`t particularly like the idea of warfare, though.

    Its impressive that they managed to finally get the fatigue issue ironed out. If I recall, before they would have to replace the rails every time it fired.

    Holy hell man, it`s amazing how we went from giant battleships in WW2 to the tiny Zumwalt class destroyer with a hundred times more firepower.

    Railguns are nice, but the energy requirement makes them as useless as lasers.

    Still, a two-foot-long tungsten rod fired out of one of these reaches upper orbit, and when it comes down it digs around half a mile into the ground, completely destroying anything within a mile of the impact point, with no explosives required.

    A much more likely weapon is the coilgun. Less damage, but far less energy needed.

    wait, railguns really do emit green light? O.o
    or what was that green thing at the first time they fired?

    i read that thing about railguns and i figured they were normal guns, with rails to accelerate the bullet.... *confused*

    That was so badass. America`s gonna pwn with that thing.
    Pea_ooter, as far as I know it uses a magnetic field to push the metal projectile along, like those bullet trains. I could be wrong though.

    It would be cool if we could use a similar mechanism to launch Unmanned Spacecraft. Granted, it`s a lot of force applied in acceleration, but if it were an longer bore with an upward Arc it might be more feasible. Considering it`s effective terrestrial range of 220 Miles, that puts the ISS within Range.

    catbarf, you`re a moron, this gun could run off of this generator:

    http://www.litepower.com/140kw_generator...

    it would fire once every 45 seconds on it, and in this configuration be HALF the size of a current MLRS system with 10 times the range and 10 times the damage. With this the fire rate would be the SAME as the current MLRS system.

    Moron.

    So WTF are you talking about with saying it`s not fesable? The only point to that would be the fact the capacitors for this would take up a room the size of two tanks, but you didn`t even mention that. For tripple the size and 10 times the damage that`s just fine to mount on a ship.

    OOOooooh, it`s called a "railgun" because it`s MADE of rails. Not because it SHOOTS rails. I`m confused, my bad.

    To add to Legion5`s comment, the Zumwalt class destroyers will have 2 36MW generator sets, not to mention if you put this on a nuclear powered ship. Needless to say the electrical power requirements will not be a major issue.

    Power is an issue, because the POWER (as opposed to the energy) is far bigger than the ships generators can handle. Hence the need for capacitors, which can provide such high powers, but take up a lot of space.

    Also, difference between a railgun and a coilgun: Railgun has current flowing along one rail, across a linking bar, and back down the other rail. The magnetic forces push the bar along the rails, which pushes the projectile. They also act to push the rails apart, hence all the bolts. Coilgun has a series of electromagnets, triggered in sequence. Advantage is no moving electrical contacts like with the railgun, drawback is need to control the switching of the magnets.

    Oh, and railway gun: Normal (often very large) artillery cannon mounted on railway tracks for motion (often curved for left-right aiming). Obsolete nowadays.
