The Electromagnetic Railgun (EMRG) is a high-risk, yet high-payoff technology that uses electricity rather than chemical propellants to launch projectiles.

FORBES: U.S. Navy Pioneers Next-Gen Electric Weaponry

The electromagnetic railgun is a long-range naval gun that will fire precision-guided hypervelocity projectiles to ranges greater than 200 nautical miles.
