Raytheon successfully fired its new Excalibur N5 projectile during a live guided flight test at Yuma Proving Ground, Ariz. A company-funded initiative, Excalibur N5 is a 5-inch/127 mm naval variant of the combat-proven Excalibur precision projectile used by the U.S. Army, the U.S. Marine Corps and several international armies. It is expected to more than triple the maximum effective range of conventional naval gun munitions and deliver the same pinpoint accuracy of the Excalibur Ib, which is in production today. Excalibur N5 can be used to support several critical mission areas including Naval Surface Fire Support, Anti-Surface Warfare (ASuW) and countering Fast Attack Craft (FAC)
