XM982 Excalibur

XM982 Excalibur

The XM982 Excalibur is a 155 mm extended range guided artillery shell presently in development by Raytheon Missile Systems and BAE Systems Bofors.Cite web|url=http://www.globalsecurity.org/military/systems/munitions/m982-155.htm|title=XM982 Excalibur 155mm Precision Guided Extended Range Artillery Projectile|accessdate=2007-05-27|publisher=Globalsecurity.org]

Overview

The "smart" round is expected to have a range of approximately 40 to 57 km depending on configuration with a circular error probable (CEP) of around 10 m. The 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. The accuracy is achieved through the use of a GPS guidance system. In contrast, standard U.S. 155 mm shells have a CEP of 200 to 300 m at moderate ranges.Cite web|url=http://www.globalsecurity.org/military/systems/munitions/m982-155.htm|title=XM982 Excalibur 155mm Precision Guided Extended Range Artillery Projectile|accessdate=2007-05-27|publisher=Globalsecurity.org]

The munition is being developed with $55.1 million in financial assistance from Sweden, which expects to receive service rounds in 2010. As of 2008, unit costs are $85,000, potentially dropping to $50,000 in full-scale production. [ [http://www.strategypage.com/htmw/htart/articles/20080828.aspx Cannot Get Enough Excalibur] ]

Initial combat experience with Excalibur in Iraq in the summer of 2007 was so successful (92% of rounds falling within 4 meters of the target) that the US Army planned to increase the production rate to 150 rounds per month vs the previous 18 rounds per month.

The combat value of the projectile was indicated by the US Army's decision to rate it as one of the "Top 10 Army Greatest Inventions of the Year Award for 2007".
