An analysis of satellite imagery and other data sources identified 274 damaged structures at 24 Middle East installations with a U.S. military presence during the first six months of the war. The assessment, which represents the most comprehensive public accounting of such damage to date, utilized lower-resolution European Union satellite data because major commercial providers halted high-resolution releases of the region early in the conflict. The methodology involved statistical change detection to flag anomalies, which were then verified through persistent visual signs of damage, fire data from NASA, and on-the-ground footage. Iranian state-affiliated media claimed responsibility for strikes that coincided with more than 250 of the identified damaged structures.

Background

• The Pentagon declined to provide specific assessments of base damage, prompting the use of alternative open-source data for verification.
• Many of the affected installations are shared with or owned by allied nations, meaning not every damaged building was exclusively used by U.S. forces.
• The analysis likely undercounts total damage due to reliance on lower-resolution imagery, and it identifies where and roughly when damage occurred rather than definitively proving the cause.
• Independent analysts from think tanks including the American Enterprise Institute and the Center for Strategic and International Studies reviewed and confirmed the findings.
