U.S. Navy Railgun Auto-Loader Test Mach Six Payload

The Office of Naval Research (ONR) demonstrates the Navy's electromagnetic railgun initial rep-rate fires of multi-shot salvos at the Naval Surface Warfare Center Dahlgren Division. The railgun relies on a massive electrical pulse, rather than gunpowder or other chemical propellants, to launch projectiles at distances over 100 nautical miles – and at speeds that exceed Mach 6.
