World’s Most Powerful Rail Gun Delivered to US Navy

The world’s most powerful functional rail gun capable of accelerating projectiles up to Mach 8 has been delivered to the Navy. The new rail gun is a 32-megajoule Electro-Magnetic Laboratory Rail Gun. The Navy eventually hopes to have 64-megajoule ship mounted rail guns. The lab version doesn’t look particularly menacing — more like a long, belt-fed airport screening device than like a futuristic cannon — but the system will fire rounds at up to Mach 8, drawing on tremendous amounts of electricity to generate the current for each test shot — via Slashdot
