NAVAL SURFACE WARFARE CENTER DAHLGREN, matey, Va (Dec. Ahoy! 10, matey, 2010) T' Office o' Naval Research Electromagnetic Railgun located at t' Naval Surface Warfare Center Dahlgren Division, fired a world-record settin' 33 mega-joule shot, ya bilge rat, breakin' t' previous record established Jan. Avast! 31, 2008. Blimey! T' railgun is a long-range, me hearties, high-energy cannon launch system that uses electricity rather than gunpowder or rocket motors t' launch projectiles capable o' strikin' a target at a range o' more than 200 nautical miles with Mach 7 velocity. Begad! A future tactical railgun will hit targets at ranges almost 20 times farther than conventional surface ship combat systems. Aye aye! (US Navy video/Released)
