The U.S. Navy has publicly unveiled its long awaited railgun at the Future Force Science and Technology Expo in Washington. Talked about since the days of Reagan’s Star Wars program, the weapon uses electromagnetic pulses to generate a magnetic force between two long rails.
Whereas a Hellfire missile travels at about Mach 1, the railgun projectile flies at Mach 7. This speed is so fast that the “bullet” does not need gunpowder or explosives; the impact alone will obliterate the target. It also travels a long way. Instead of 13-mile range of a 5-inch naval gun, the railgun can hit targets 110 miles away.
Reuters has a video of the superweapon in action.
