Fox News reports that the Navy’s experimental Rail Gun has tripled its projectile energy output …

An electromagnetic railgun offers a velocity previously unattainable in a conventional weapon, speeds that are incredibly powerful on their own. In fact, since the projectile doesn’t have any explosives itself, it relies upon that kinetic energy to do damage. And at 11 a.m. today, the Navy produced a 33-megajoule firing — more than three times the previous record set by the Navy in 2008.

“It bursts radially, but it’s hard to quantify,” said Roger Ellis, electromagnetic railgun program manager with the Office of Naval Research. To convey a sense of just how much damage, Ellis told FoxNews.com that the big guns on the deck of a warship are measured by their muzzle energy in megajoules. A single megajoule is roughly equivalent to a 1-ton car traveling at 100 mph. Multiple that by 33 and you get a picture of what would happen when such a weapon hits a target.
