Direct proof of use
The GBU-24 Paveway III is directly documented in the 1990 Gulf War through the U.S. Government Accountability Office's postwar evaluation of the Operation Desert Storm air campaign. GAO's munition-cost and expenditure table lists 284 GBU-24 laser-guided bombs and 897 GBU-24/109 laser-guided bombs expended during Desert Storm.
Air Power Australia's contemporary technical review of Desert Storm precision-guided munitions also identifies the newer GBU-24 and GBU-27 Paveway III weapons as Gulf War laser-guided bombs fitted to Mk 84 or BLU-109 bomb bodies. It describes the GBU-24A/B with the BLU-109/B penetrator warhead as the principal Paveway III subtype used in the Gulf.

Campaign chronology
Operation Desert Storm's air campaign began on January 17, 1991 and ran until the February 28, 1991 ceasefire. GAO describes the campaign as a 43-day U.S.-led coalition air campaign against Iraq, and its public expenditure table places the GBU-24 and GBU-24/109 inside the laser-guided-bomb inventory used during that campaign.
The sources support use by coalition air forces as an air-dropped munition, not a transfer, possession-only, or captured-use claim. The clearest public count is GAO's combined 1,181 GBU-24-family expenditure figure when the GBU-24 and GBU-24/109 rows are read together.

Operational role
The sourced record places the GBU-24 on the coalition side of the 1990 Gulf War in U.S.-led air operations. Its documented role was air-delivered precision strike with a 2,000-pound-class Paveway III laser-guided bomb, including a hard-target role when paired with the BLU-109 penetrator body.
Air Power Australia describes F-111F/Pave Tack aircraft using GBU-24s and GBU-15s against bridge supports during the late-January road and bridge interdiction phase. That source also credits the F-111 force's campaign contribution in part to Pave Tack and GBU-10/12/15/24 weapons, while GAO cautions more broadly that public Desert Storm data do not always permit precise target-level conclusions for each munition.
