The first XM982 Excalibur artillery shell fire test was conducted in early November 2004. The shell hit the target area less than 3.4 meters from the aim point located at approximately 20 kilometers from the artillery gun, the new XM777 howitzer, which fired Excalibur. Its precision strike capability represents lower collateral damage since its fielding in 2007 with the US Army's 25th Infantry Division which is also equipped with the Stryker vehicle family. In June 2006, the US Army awarded Raytheon a $42.7 million contract for fiscal year 2006 production of 335 Excalibur projectiles and related test articles and services. Excalibur's accuracy was set to 4.5 meters after 12 successful guided flights. In 2011, the program's scope was scaled down from 30,000+ to only 7,474 units to be procured.

The Excalibur Block Ia-1 is a production variant qualified for ranges of 15 miles or 24 kilometers. The Excalibur Block Ia-2 is qualified for ranges of 26 miles or 40 kilometers. The Raytheon M982E1 Excalibur Block Ib is a lower-cost, higher-reliability alternative to the Block Ia round.

The Raytheon-funded Excalibur S is a 155mm artillery shell featuring a dual-mode GPS and laser guidance system. The Excalibur S round is fired with a target assigned by GPS location but can score a direct hit on a different target after being terminally guided with a laser designator. This variant adds a laser spot tracker (LST) to the Excalibur Ib artillery projectile. The new guided projectile is intended to attack moving targets, engage targets that have re-positioned after firing, or change the impact point to further avoid casualties and collateral damage. The first live fire test of the Excalibur S was announced in June 2014.

The Raytheon Excalibur N5 is a 5-inch (127mm) artillery projectile intended for use by surface warships utilizing 127mm cannons such as the Mk 45 naval gun system. The N5 is the naval variant of the Excalibur round and could be upgraded with the laser guidance of the Excalibur S projectile. The first live fire demonstration of the Excalibur S is planned for late 2014.

The Excalibur Shaped Trajectory (EST) is a further variant of this precision guided projectile introduced in October 2018 to meet the US Army requirements. The EST variant enables field commanders to eliminate targets in hard-to-reach locations or on-the-move by selected the projectile’s terminal or final phase attack angle. For example Excalibur EST makes possible to engage a bunker positioned on the opposite side of a mountain slope, target a multi-story building from the side rather than the top or defeat enemy assets positioned under highway overpasses. Raytheon completed the EST variant development in October 2018 being ready to move forward with serial production and fielding.
