^One Million Joules... duh!

Seriously though, she probably doesn`t. She`s just reading the cue cards. The actual muzzle velosity was over mach 7 per the written article. The link is provided.

Oh by the way, a joule is a unit of energy, equivalent to 1 newton exerted over a distance of 1 meter or 1N x m.

A megajoule is a unit of work/energy. It makes no sense to say that something was fired with a velocity of xx megajoules, although it would make sense to describe the accelleration upon firing. (F=ma, w=Fd, m is constant, d [distance] would obviously increase, increasing the overall work w. W is mostly dependent on accelleration of the projectile, since mass would have to be pretty small). However, it would still make the most sense to say something fired with a force of xx kilonewtons.

Actually all us military equipment has to be hardened against EMP, and must pass an EMP pulse test before it is used in the field

Wow...just think...when the oil is gone and we dont have anything to fall back on because we didnt put enough cash into funding alternate energy research and production...we will have all these new badass weapon to kill each other. Horse drawn electromagnetic railguns FTW!

Go to google and type define:joule

It`s an overlooked seach-option that I use a lot. Try it.

"During the test, the gun almost instantaneously propelled an aluminum slug weighing slightly more than 7 pounds to Mach 7 – or more than seven times the speed of sound."


"Thursday’s test produced a record 10.86 megajoules, which sent the 7-pound aluminum slug at Mach 7 (more than 5,000 mph) for 80 meters, a roughly 20-millisecond ride."

The flames were from friction.
