… In 2016. "23 pounds ain't heavy. But it sure hurts when it hits you going at seven times the speed of sound. That's what a prototype Navy weapon called a "rail gun" can do, and it does it without a single gram of gunpowder or rocket fuel — just electricity. For many missions, a rail gun is better not just than current cannon but than the laser weapons the Navy is testing this summer in the Persian Gulf (I'll explain why in a minute). And, after years in development and hundreds of test shots on land — see the video for a small sample of the destruction — the rail gun is finally going to go to sea. "We're beyond lab coats, we're into engineering now," Adm. Jonathan Greenert, the Chief of Naval Operations, told the audience at the Navy League's annual megaconference here, Sea-Air-Space 2014. "It's going on a Joint High Speed Vessel in 2016."…"

Barrel wear is a real constraint. |

Possible dumb question: If it's fired without gun powder using just electricity, why the flame out the barrel when fired? |

My guess is when you push the air out the barrel at Mach 7, it heats up a bit. |

I love how some news stories are saying "super top secret gun design" hell they have been working in it since before I was 17 years old and I have been reading about it all along because we build a 4ft long 100 caliber one in shop class that could blast through 3 solid cinder blocks at 2000+ FPS. That was in 1988-89 so just how secret could this weapon ever be? I just don't understand why it has taken the navy so long to build such a simple weapon when high school students could build a working prototype 27 years ago. @ PzGeneral: the flash is part of the barrel and guide melting and turning to plasma :) makes for a cool light show. also one of the big problems firing faster then MK5. @ Stryderg: the air is vented past the mags to stop presser buildup and to help cool them. Yes I have been reading a lot about this weapon for years. :) I know they have over come a lot of big problems. last time I look the so called tube was not a solid closed part. |

Definitely air pollution then. So, the EPA will ban its use. |

If you think that is air pollution check out the gasses from 1 oz of modern gun powder :) |

Possible dumb question: If it's fired without gun powder using just electricity, why the flame out the barrel when fired? Copper plasma, the air heated to the point that it splits from N2 and O2 dimers to monatomic and highly reactive N and O, which then rather explosively recombine… And that doesn't mention the billion-volt artificial lightning bolt created inside the barrel! |
