Artillery experts at the Raytheon Co. Missile Systems segment in Tucson, Ariz., test fired nine rounds of the Excalibur Ia-2 precision-guided artillery shell in U.S. Army lot acceptance tests, which means the Excalibur round is ready for U.S. Army and Marine Corps use in Afghanistan. Building on the technology of the Excalibur Ia-1, which was fielded in 2007, the Excalibur Ia-2 includes several upgrades designed to meet the projected threat, while maintaining accuracy of better than six meters. Excalibur Ia-2 also extends the range of Excalibur Ia-1 from 24 to 37.5 kilometers, which is 50 percent farther than conventional artillery. Excalibur’s first-round precision enables it to defeat fleeting and persistent targets. Excalibur complements air-delivered precision when close air support is unavailable or not the best option. With more than 500 rounds fired to date, Excalibur has made its mark on the battlefield.
