Direct proof of use
The GBU-16 Paveway II 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 table lists 219 GBU-16 laser-guided bombs expended during Desert Storm.
The Federation of American Scientists' GBU-16 profile gives the same Desert Storm count and attributes virtually all of those drops to U.S. Navy A-6E Intruders, noting that the aircraft could self-designate targets for laser-guided-bomb delivery.

Campaign chronology
Operation Desert Storm's air campaign ran from January 17, 1991 to February 28, 1991. GAO describes it as a 43-day U.S.-led coalition air campaign against Iraq, with large-scale use of aircraft, munitions, and missiles.
Within that campaign, the public record supports GBU-16 use as an air-delivered laser-guided munition rather than as a transferred or captured weapon. The available sources identify the U.S. Navy as the documented user and the A-6E Intruder as the principal delivery aircraft for the recorded 219 GBU-16 drops.

Operational role
The sourced record places the GBU-16 on the coalition side of the conflict in U.S. naval air operations. Its documented role was air-delivered precision strike and interdiction: a 1,000-pound Mk 83-class bomb body fitted with a Paveway II semi-active laser guidance kit and released from aircraft against Iraqi targets.
NAVAIR identifies the GBU-16 as a 1,000-pound bomb modified with the common Paveway II laser-guidance kit, and FAS lists its mission as air interdiction against mobile hard, fixed soft, and fixed hard target categories. The Desert Storm sources do not provide a public sortie-by-sortie target ledger for the 219 GBU-16 drops, so the strongest supported claim is the munition count, user, platform, and broad air-interdiction role.
