The M982 Excalibur (previously XM982) is a 155 mm extended-range guided artillery shell developed in a collaborative effort between the U.S. Army Research Laboratory (ARL) and the United States Army Armament Research, Development and Engineering Center (ARDEC). [5]
Each Excalibur round costs around $100,000, while even unguided 155 mm rocket-assisted projectiles, such as the experimental XM1113, cost almost $15,000 each.
The M982 Excalibur was fielded as a guided shell that effectively hit within 6 m (20 ft) of a target, but the Army developed the XM1156 as a cheaper alternative. The PGK fuse can be screwed onto existing M549A1 and M795 projectiles, be fired from M109A6 Paladin and M777A2 Howitzer artillery systems, and hits within 50 m (160 ft) of the target ...

XM1113 extended-range artillery round, shown here at a range demonstration, uses a rocket-assist motor. M777A2 – Block 1A software upgrade. Addition of an Enhanced Portable Inductive Artillery Fuze Setter (EPIAFS) to enable Excalibur and precision munition compatibility.
The United States developed the similar M898 SADARM system (which also descended on a ballute to attack the top surfaces of armoured vehicles), but this was discontinued in favor of the GPS guided M982 Excalibur round. US artillery units also largely deploys the M712 Copperhead laser-guided round for the anti-tank role.
The M795 is a 155 mm high-fragmentation, steel (HF1)-body projectile, filled with 10.8 kilograms (23.8 lb) of TNT.It weighs approximately 47 kilograms (103 lb). The high-fragmentation steel body is encircled by a gilding metal rotating band, making it compatible with 3W through 8S (M3A1 through M203A1) zone propelling charges across all current 155 mm howitzers.
