Deadly Accurate GPS Guided Artillery

The M982 Excalibur (previously XM982) is a 155 mm extended range guided artillery shell developed by Raytheon Missile Systems and BAE Systems Bofors. It is a GPS-guided munition capable of being used in close support situations within 150 metres (490 ft) of friendly troops. Excalibur was developed as a longer-ranged alternative to conventional artillery shells, with GPS guidance for improved accuracy. Excalibur has a range of approximately 40 to 57 kilometres (25 to 35 mi) depending on configuration, with a circular error probable (CEP) of around 5 metres (16 ft) to 20 metres (66 ft). 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 munition was co-developed by United States-based Raytheon Missile Systems (guidance system) and the Swedish BAE Systems Bofors (body, base, ballistics and payload). Excalibur is used to minimize collateral damage, for targets beyond the range of standard munitions, for precise firing within 150 metres (490 ft) of friendly troops, or when firing in a straight line from the launching cannon is limited by terrain.
