New precision munition will protect against swarming boat threats

Raytheon Company has initiated an internally funded program to enhance its combat-proven 155mm Excalibur GPS-guided projectile with a new guidance and navigation unit (GNU) with a semi-active laser (SAL) end-game targeting capability. Addition of the SAL seeker will allow the munition to attack moving targets, attack targets that have re-positioned after firing, or change the impact point to avoid casualties and collateral damage.

This new Excalibur variant using SAL guidance paves the way for GPS-guided Excalibur Ib customers to upgrade their Excalibur Ib guidance and navigation units with a GPS/SAL capability. Recent tests of the SAL seeker have demonstrated the robustness of the design in a severe gun-firing environment.

In addition to 155mm artillery land forces worldwide, the GPS/SAL capability will be available for both 155mm and 5-inch (127mm) naval guns to address moving targets on land and at sea. Counter-swarming boat capability will be the prime focus of the at-sea moving target capability using a high-firing rate, large caliber, affordable munition that can be fired from land or sea platforms. The transition to the naval 5-inch configuration is easily made as the existing 155mm Excalibur Ib GNU design also fits in a 127mm projectile body.
