Direct proof of use
USCENTAF's April 2003 Operation Iraqi Freedom munitions summary listed one GBU-28 laser-guided bomb among guided weapons expended by coalition air forces. Human Rights Watch reproduced the same air-war appendix line in Off Target, identifying the GBU-28 as a 5,000-pound bunker-buster and citing USCENTAF's Operation Iraqi Freedom data.
The available direct sources support use by the U.S.-led coalition at the campaign level. They do not identify the exact aircraft, target, date of release, or strike location for the single GBU-28 listed in the 2003 Iraq War expenditure data.

Timeline
The source-backed timeline for this conflict is limited to aggregate air-campaign reporting. The weapon's documented 2003 Iraq War use falls within the Operation Iraqi Freedom air campaign summarized by USCENTAF on April 30, 2003.
Human Rights Watch published Off Target in December 2003 and used the USCENTAF munitions data as an appendix source for weapons used in the air war, including the single GBU-28 expenditure.

Narrative
In the 2003 Iraq War, the GBU-28 appeared as a rare hard-target munition rather than a routine strike weapon. USCENTAF's munitions table placed it among laser-guided bombs and recorded only one GBU-28 LGB expended, compared with thousands of smaller GBU-12 and JDAM-series guided bombs in the same campaign summary.
That limited count fits the weapon's role as a specialized penetrator for hardened or buried targets. The public aggregate data confirms one use in the conflict but does not provide enough detail to connect the bomb to a named bunker, leadership site, or specific sortie.
