 The three sub-munitions fly in a formation about 1.5 meters in radius, and have enough kinetic energy to manoeuvre to meet a target evading at 9 g at 7,000 meters.Earlier laser guidance systems used a single beam that had to be kept on the target at all times, the missile homing in on laser energy reflected off the target, if it moved off the target, the reflection would end and guidance would be lost until the target was regained.The problem could be reduced by making the laser's beam wider, but only at the cost of lowering accuracy and reducing the amount of energy being reflected.
