El sistema de artiller\u00eda Excalibur es un proyectil calibre 155 mm guiado por GPS, en servicio desde hace algunos a\u00f1os y de probada eficiencia, con m\u00e1s 1400 disparos realizados en combate. La nueva versi\u00f3n Excalibur\u2013S, agrega la capacidad de batir tambi\u00e9n blancos m\u00f3viles, mediante la incorporaci\u00f3n de un sistema de guiado por l\u00e1ser para la etapa final de la trayectoria. Esto agrega una extraordinaria capacidad a la artiller\u00eda de campa\u00f1a, tradicionalmente apta para batir blancos est\u00e1ticos.<\/p>\n
WASHINGTON \u2014 A new version of Raytheon\u2019s Excalibur precision-guided munition<\/a> demonstrated in a U.S. Navy test at Yuma Proving Ground, Arizona, that it can change course to hit moving targets.<\/p>\n<\/div>\n The Excalibur S proved it can \u201csurvive the shock and stress\u201d of being fired from a Howitzer, then transition from a GPS-guided capability<\/a> to laser guidance and hit a moving target, a Feb. 5 company statement said.<\/p>\n<\/div>\n The “S” version has GPS and a semi-active laser seeker to get after mobile land and maritime targets in GPS-contested environments without a loss in range capability.<\/p>\n<\/div>\n The Army and the Navy both use Excalibur Increment B projectiles, which can be upgraded with the S capabilities, the company said.<\/p>\n<\/div>\n \u201cUsing artillery to engage moving targets gives soldiers more flexibility,\u201d Sam Deneke, Raytheon\u2019s land warfare systems vice president, said in the statement. \u201cArtillery is typically used to hit stationary objects, but Excalibur S expands the capability of artillery on the battlefield.\u201d<\/p>\n Excalibur<\/a> is a known to be a precise weapon, typically hitting less than 2 meters from the target, according to Raytheon.<\/p>\n<\/div>\n Excalibur has been fired more than 1,400 times in combat. The Army shot a round from the gun tube of a prototype of the service\u2019s Extended-Range Cannon Artillery system <\/a>and hit a target at 62 kilometers. The service is developing the ERCA system as part of its Long-Range Precision Fires modernization program, which is the Army\u2019s top priority within its modernization portfolio.<\/p>\n<\/div>\n The prototypes consist of a Paladin howitzer with an M109A7 chassis that upgrades the Paladin Integrated Management\u2019s turret with a 58-caliber, 30-foot-long gun tube capable of shooting farther than 70 kilometers.<\/p>\n
