Sonofabitch. A rail gun that pushes a 7 pound projectile at over 5000 mph.
Operational range of 200 miles.

Think about that, folks. E = 0.5 * m * v^2

Convert (loosely): 7 pounds to 3kg, 5000 mph to 8000 kph to 8000000 meters per hour to 2240 meters per second (that's goddamn fast, by the way)

E = 0.5 * 3 * 2240^2 = 7.9 MJ

That's a lot of fucking J.

Seriously. Like 2000kg of TNT, or ~5040 pounds.

That's fucking cool.

* footnote: no, no footnote, but it was just on an episode of Universe that the Navy, in 2008, created this rail gun, and they said it's the most powerful rail gun in the world. Makes me wonder if we have more powerful ones now.

3. for my visualization - 2240 meters/sec = @25 football fields or so/sec.
