True precision weapon
The Excalibur projectile is a true precision weapon, impacting at a radial miss distance of less than two meters from the target. Unlike “near precision” guidance systems, the Excalibur weapon provides accurate first-round effects at all ranges in all weather conditions. This weapon system also extends the reach of .39-caliber artillery to 40 kilometers, .52-caliber artillery to 50 kilometers, and .58-caliber artillery to 70 kilometers.
By using the Excalibur projectile's level of precision, there is a dramatic reduction in the time, cost and logistical burden associated with other artillery munitions. Analyses have shown that on average, it can take at least 10 conventional munitions to accomplish what one Excalibur weapon can.
The Excalibur munition is compatible with every howitzer with which it’s been tested. This weapon is fully qualified in multiple systems, including the M777, M109 series, M198, the Archer and PzH2000. It’s also currently compatible with the AS90, K9, DENEL G6, and CAESAR 6x6 systems. Excalibur has been successfully fired from the U.S. Army's Extended Range Cannon Artillery, or ERCA, and plans are underway to integrate it with other mobile artillery systems.
The Excalibur projectile’s precision, coupled with its ability to be integrated on multiple gun systems, enables both the U.S. and its coalition partners to provide overmatch capabilities against land targets in a variety of combat environments. This includes stationary land targets.
Sweden, Canada, Australia, Jordan, India, Spain and the Netherlands have chosen the Excalibur precision-guided projectile to address vital security interests, and several other international partners are finalizing procurement plans.
Raytheon Missiles & Defense has developed the Enhanced Shaped Trajectory, or EST, software for the current Ib that enables soldiers to eliminate targets in hard-to-reach locations by selecting the projectile's terminal or final phase attack angle. It was successfully tested in 2018 and is now being deployed to U.S. forces.
Excalibur HTK features an armor-penetrating warhead and leverages the proven and tested Small Diameter Bomb design. This variant autonomously locates the target with an all-weather seeker design effective against imprecisely located and moving targets.
The company has developed a laser-guided version of the projectile, the Excalibur S. This variant incorporates a digital semi-active laser seeker, allowing it to hit moving targets and engage and strike targets without accurate location information. It also reduces the risk associated with GPS jamming.
A 5-inch naval variant, the Excalibur N5 munition, is a sea-based projectile that has more than doubled the maximum range of conventional 5-inch munitions and provides the same accuracy as the land-based version.
The Excalibur precision-guided projectile is co-developed by Raytheon Missiles & Defense and BAE Systems Bofor.
