The U.S. Navy yesterday test fired an incredibly powerful new big gun designed to replace conventional weaponry aboard ships. Sci-fi fans will recognize its awesome power and futuristic technology.
The big gun uses electromagnetic energy instead of explosive chemical propellants to fire a projectile farther and faster. The railgun, as it is called, will ultimately fire a projectile more than 230 miles (370 kilometers) with a muzzle velocity seven times the speed of sound (Mach 7) and a velocity of Mach 5 at impact.
The test-firing, captured on video, took place Jan. 31 in Dahlgren, Va., and Navy officials called it the “world’s most powerful electromagnetic railgun.”
Oh great, now the US has railguns too….
But I hope they know about the problems with railgun technology..
1. The first problem with a practical railgun is the power supply. But a big ass naval ships nuclear reactor should have the juice needed.
2. And one other problem is the gun itself. It literally tears itself a part. They lack the material science to withstand the violent EM forces used to launch the projectile.
