The F-16 Fighting Falcon is directly documented in the 2003 Iraq War through U.S. Air Force reporting and official Air Force reference material. The Air Force fact sheet identifies the F-16 as a major post-September 11 combat aircraft and states that it flew thousands of sorties in support of Operation Iraqi Freedom.
Air Force reporting on the opening air campaign listed F-16 Fighting Falcons among the aircraft that flew coalition strike missions on March 21, 2003, as airpower operations expanded over Iraq. Later Air Force reporting from Balad Air Base documented F-16s flying combat missions, dropping precision-guided munitions, and conducting close-air-support tasks during the continuing Operation Iraqi Freedom campaign.

Timeline
During the initial combat phase, Operation Iraqi Freedom air operations ran from March 19 to April 18, 2003 in the Combined Forces Air Component Commander's reporting period. Coalition aircraft flew 41,404 sorties in that 720-hour period, with fighter and bomber aircraft making up the main strike categories.
On March 21, 2003, Air Force reporting placed F-16 Fighting Falcons in the coalition strike force that attacked Iraqi regime targets at the start of the air campaign. The type remained in use after the invasion phase: a June 2007 Air Force article from Balad described F-16 squadrons rotating through Iraq, with one squadron commander stating that his unit had been among the first non-stealth aircraft over Baghdad on day one of Operation Iraqi Freedom.

Operational role
The sourced record places the F-16 on the United States and coalition side of the 2003 Iraq War. Its documented roles included strike missions in the opening air campaign, suppression of enemy air defenses, precision attacks, and close air support from Balad Air Base during later Operation Iraqi Freedom rotations.
A Center for Strategic and Budgetary Assessments assessment describes the Operation Iraqi Freedom targeting system selecting an F-16 strike aircraft for a time-sensitive attack on a Ba'ath Party headquarters associated with Ali Hassan al-Majid, with the aircraft destroying the villa with precision-guided munitions. The same assessment places that example within a wider pattern of dynamic retargeting and air attacks in support of ground forces.
The later Balad reporting shows how the F-16 shifted into a continuing Iraq role after the initial invasion. Misawa-based F-16 squadrons were described as maintaining suppression-of-enemy-air-defense capability while flying close air support with advanced targeting pods, employing ordnance against enemy forces, and supporting ground operations with shows of force and non-traditional intelligence, surveillance, and reconnaissance.
