US Bomb, Guided, GBU-24A/B
The GBU-24/B, GBU-24A/B, and GBU-24B/B are air-to-surface bombs with a low- level laser guidance system. Target illumination is achieved by a laser illumination device which may be ground mounted or may be carried in a target spotting aircraft. The GBUs are used against heavily defended tactical surface targets when a high degree of accuracy is required. The GBU-24A/B consists of a WGU-39/B guidance control unit, a BSU-84/B air foil group, and an ADU-548/B adapter group attached to a BLU-109/B penetrator bomb. The GBU-24B/B consists of a WGU-39B/B guidance control group, a BSU-84/B air foil group, and an ADG-770/B adapter group attached to a BLU-109A/B penetrator bomb.
