The munition was used during Operation Desert Storm, and, according to the Air Force, hit 88 percent of its targets. During Desert Storm the GBU-12 was dropped by F-111Fs, F-15Es, and A-6s, mostly against fixed armor. It was the F-111F tank-busting weapon of choice. Of the 4,493 GBU-12s employed, over half were dropped by the F-111F. An aircraft using an unguided general-purpose (GP) 500-pound (lb) bomb (i.e., a Mk-82) to attack a dug-in tank has a low probability of success in comparison to a laser-guided 500 lb weapon (i.e., a GBU-12) because the accuracy of the latter is much better. Tank plinking, expending a single 500-pound GBU-12 worth $10,000 to destroy a $1.5 million T-72 tank, is not a bad return on tax dollars.
There are two generations of GBU-12 LGBs: Paveway I with fixed wings and Paveway II with folding wings. Paveway II models have the following improvements: detector optics and housing made of injection-molded plastic to reduce weight and cost; increased detector sensitivity; reduced thermal battery delay after release; increased maximum canard deflection; laser coding; folding wings for carriage, and increased detector field of view. (Paveway II's instantaneous field of view is thirty percent greater than that of the Paveway I's field of view).
On 05 January 2000 Raytheon Systems Company, Tucson, Ariz., was awarded a $43,537,250 firm-fixed-price contract to provide for 3,420 MXU 650/B Air Foil Groups, 2,245 MAU 169 H/B Guidance Control Sections, and associated data, in support of the GBU 12 Paveway II Laser Guided Bomb. There was one firm solicited and one proposal received. Expected contract completion date is April 1, 2000. Negotiation completion date was Dec. 29. 1999. Ogden Air Logistics Center, Hill AFB, Utah, is the contracting activity (F42630-00-C-0005).
