They have successfully tested a rail gun for the US Navy

[thewayne]

8 MEGAJOULES OF POWER! The one they plan on fielding will be at an estimated 64 megajoules.

It can shoot 95 miles UP. And has an estimated range of 200 miles, and the projectile will get there in six minutes. A Tomahawk cruise missile takes eight minutes.

So the range on the guns increases to such that they don't even need to be particularly near the battle site to provide support. I wonder what kind of craters those shells will make when they touch down?
