XM/982 EXCALIBUR is a 155 mm trajectory correctable artillery shell. The shell is fired at high elevation and then glides from its apogee to the assigned target. The rear section of EXCALIBUR is equipped with a base bleed aggregate and rotating stabilization wings. There are deployable canard wings on the front section for trajectory guidance. The shell can deliver different types of warheads and has a range of aprox 60 km.
EXCALIBUR is prepared, programmed and then fired just like a normal shell. The glide flight to target starts after reaching apogee. The shell is corrected in flight towards the pre-programmed trajectory by the GPS-supported navigation system and guidance system.
