World’s Most Powerful Electromagnetic Railgun Tested by the U.S. Navy

Quote:
At full capability, a future rail gun will be able to fire a projectile more than 200 nautical miles (ten times farther than current Mk 45 five inch guns) at a muzzle velocity of mach seven and impacting its target at mach five. These high velocity projectiles will be able to destroy targets by kinetic energy, rather than with conventional explosives.

"uses electromagnetic energy instead of explosive chemical propellants to fire a projectile"

So whats all the fire from??

I think that's "Plasma" because it's going so fast, it ignites the air.

See meteors and the Space Shuttle re-entry.

That is some wild stuff! My son built a small rail gun for a high school electronics project that would shoot a nail across a room and into a 2X4, but this thing is very impressive. I can't imagine the power requirements to fire such a large device. It took 20 amps @ 110v just to shoot a nail 15 feet and into a piece of wood.

Note the atmospheric lensing at the front of the projectile!

This test was around 10 "megajoules" IIRC, and this was only about 1/3 of potential.

Cool.

Best,

Kurt
