Navy: Dahlgren Railgun test is successful

the Navy has the goal of using the railgun to fire 200 nautical miles with Mach 7 velocity using 64 megajoules with full deployment to ships in about 2020-2025.

The Office of Naval Research said railgun achieved a world-record 33-megajoule shot. That energy measurement means the Navy could fire projectiles at least 110 miles.

var _phPubId = ‘dkr04’;
var _phWidth = ‘300’;
var _phHeight = ‘250’;
var _phBgColor = ‘#ebebeb’; // For background color
var _phBorderColor = ‘#999999’; // For border color
var _phTextColor1 = ‘#006699’; // For Link 1 color
var _phTextColor2 = ‘#333333’; // For Link 2 color
var url = ‘http://ph.affinity.com/ph-adcloud-m.js?’ + ‘h=’+escape(location.hostname) + ‘&pb=’ + escape(_phPubId);
document.write(unescape(“%3Cscript src='” + url + “‘ type=’text/javascript’%3E%3C/script%3E”));

The railgun uses kinetic energy to fire a projectile. The new munition would eliminate the need for a high-energy explosive, and put sailors farther away from harm’s way.

The railgun is being developed for use on a wide range of ships.
