![]() A lower cost alternative to the Excalibur is to use the US Army designed M1156 Precision Guidance Kit to turn existing 155 mm shells into precision weapons. Excalibur's extended range is achieved through the use of folding glide fins, which allow the projectile to glide from the top of a ballistic arc towards the target. While much more expensive at $68,000 per shell compared to a $800 unguided M777 shell, it is less expensive than the $150,000 rocket used in US guided-missile systems like M142 HIMARS and M270 Multiple Launch Rocket System. Excalibur has a range of approximately 40 to 57 kilometers (25 to 35 mi) depending on configuration, with a circular error probable (CEP) of 4 m, while unguided Western artillery shells can land up to 150 m (500 feet) from the target at a range of 24 km (15 miles). Įxcalibur was developed as a longer-range alternative to conventional artillery shells, with GPS guidance for improved accuracy. By October 2018, over 1,400 rounds had been fired in combat. Versions that add laser-guidance capability and are designed to be fired from naval guns began testing in 2015. By 2016, unit costs were reduced to US$68,000 per round. In 2015 the United States planned to procure 7,474 rounds with a FY2015 total program cost of US$1.9341 billion at an average cost of US$258,777 per unit. ![]() ![]() It is a GPS- and inertial-guided munition capable of being used in close support situations within 75–150 meters (250–490 ft) of friendly troops or in situations where targets might be prohibitively close to civilians to attack with conventional unguided artillery fire. The Excalibur was developed and/or manufactured by prime contractor Raytheon Missiles & Defense, BAE Systems AB ( BAE Systems Bofors) and other subs and primes in multiple capacities such as Camber Corporation and Huntington Ingalls Industries. Army Research Laboratory (ARL) and the United States Army Armament Research, Development and Engineering Center (ARDEC). The M982 Excalibur (previously XM982) is a 155 mm extended-range guided artillery shell developed in a collaborative effort between the U.S. ![]()
