A GPS-guided, inertial measurement unit-aided, fin-stabilized, 155mm projectile flies a ballistic trajectory during its ascending branch, then a guided trajectory during its descending branch to preprogrammed target coordinates. It provides precision guidance and dramatically improves accuracy to less than 10 meters compared with hundreds of meters for conventional artillery ammunition. This increased reliability increases the probability of destroying the target and decreases the number of rounds needed to fire. The range capability increases from 25.3 kilometers to 37.5 kilometers.
