In the encyclopedia it says that this weapon fires a round at 49,212 fps. Thats about mach 44, although our current railgun can fire a round at mach 7, does that make sense?

Yes, more or less. It's five hundred years in the future, and Orbital Defense Stations fire rounds at 'a significant fraction of the speed of light'. It's hardly unreasonable to see this thing shooting a small projectile at that speed.[[User talk:Didactic Angel|Didactic Angel]] 00:18, 21 October 2012 (EDT)

==Energy==

I did some mathematics regarding its muzzle energy. I assumed that, since from descriptions it seems to fire a tungsten penetrator round (not dissimilar to the DU penetrators used in anti-tank rounds), the projectile would be very long for a .21 calibre projectile. So the weight of the projectile would be perhaps a third of a pound. My mathematics states that, at 15,000 metres per second, it'd have a muzzle energy of roughly 15,000,000 joules. For comparison, a high-grain .50 BMG round has about 15,000 joules of force. That's a difference of ''one thousand times''. I'm a little doubtful about putting that figure on the page, though, since 15,000,000 joules is ''extraordinarily'' high - as in, enough to take out a Scorpion tank in one hit, or to punch through the hull of a UNSC Frigate. Can anyone check my maths here?[[User talk:Didactic Angel|Didactic Angel]] 00:18, 21 October 2012 (EDT)
