The Excalibur N5 is a Raytheon-funded initiative for a new 5-inch (127-millimeter) naval variant of the combat-proven Excalibur precision projectile. Raytheon officials say they expect the N5 to more than triple the maximum effective range of conventional naval gun munitions and deliver pinpoint accuracy. "Excalibur N5's range, precision and lethality will revolutionize naval gunfire and increase the offensive firepower of our Navy's destroyers and cruisers."
THE MIL & AERO BLOG, 6 Oct. 2015. U.S. military and defense industry smart munitions experts may be on the verge of another technology-crossover success story as industry technicians work to convert a satellite-guided artillery munition for use with naval guns aboard Navy surface warships.
At issue is the U.S. Army Raytheon M982 Excalibur Global Positioning System (GPS)-guided 155-millimeter artillery shell, which has a built-in ruggedized GPS receiver and uses satellite signals to help guide itself to its intended target.
The Excalibur artillery shell first was fielded in Iraq in 2007 for urban or complex-terrain engagements in which collateral damage must be kept to a minimum. It can hit targets as far away as 25 miles, or detect and attack moving targets in cities and other complex terrain after being fired at high angles.
Now engineers at the Raytheon Co. Missile Systems segment in Tucson, Ariz., are working on using Excalibur technology for naval guns to enable surface warships to engage sea-borne or land-based targets with precision accuracy.
