Final answer:
The GBU-12 Paveway II adds a Precision Laser Guidance set to a conventional bomb, enabling high-accuracy targeting through laser-seeking technology.
Step-by-step explanation:
The guided-bomb unit that adds a Precision Laser Guidance set is the GBU-12 Paveway II. This is a laser-guided bomb, and the precision guidance is achieved by adding a laser seeker and computer controls to a conventional unguided bomb. This technology allows the bomb to be directed to its target with high accuracy by aiming at laser energy reflected from the target, which is usually designated by forces on the ground or by the aircraft itself. The Paveway system has various versions with improvements in range and precision, including the GBU-10 and GBU-24, expanding the United States' military capabilities in precision strike warfare.
The guided-bomb unit that adds a Precision Laser Guidance set is the Laser Joint Direct Attack Munition (LJDAM). The LJDAM is a guided bomb unit that can be attached to various types of bombs and enables them to be guided using laser guidance systems. This technology improves the accuracy of the bombs, allowing them to hit their targets with precision.
