GBU-12 PAVWAY II

The Guided Bomb Unit-12 (GBU-12) utilizes a Mk82 500-pound general purpose warhead. The operator illuminates a target with a laser designator and then the munition guides to a spot of laser energy reflected from the target. The GBU-12 is a member of the Paveway II series of laser guided bombs (LGBs). These weapons are hybrids. At the core of each is a bomb: a 500-pound Mk 82 for the GBU-12, a 1,000-pound Mk 83 for the GBU-16 and a 2,000-pound Mk 84 for the GBU-10. A laser guidance kit is integrated with each bomb to add the requisite degree of precision. The kit consists of a computer control group at the front end of the weapon and an airfoil group at the back. When a target is illuminated by a laser - either airborne or ground-based - the guidance fins (canards) react to signals from the control group and steer the weapon to the target. Wings on the airfoil group add the lift and aerodynamic stability necessary for in-flight maneuvering.
