has a new laser-guided, 155mm “Excalibur” artillery shell — with technology that allows the weapon to change course mid-flight — that it’s pitching to the Army and Navy.

Raytheon missile systems is investing in a dual-mode Excalibur variant called Excalibur S. It maintains its GPS guidance system but also adds a laser spot tracker which is a seeker that will detect laser energy from a laser designator and guide to that energy spot on a target,” said Paul Daniels, business development lead for the project, reported Thursday.

One of the advantages of the Excalibur shell is that it can operate in GPS-denied environments, the defense website reported. In the event that an enemy was able to block its GPS guidance system the shell could still be guided by a laser designator in the air or on the ground.
