Overview
On February 28, 2026, the United States, in coordination with Israel, initiated military operations against Iran initially under the designation Operation Epic Fury (OEF). The conflict has involved air, maritime, and missile combat engagements across the Middle East. The pace of combat activity declined amid a ceasefire in April. Within weeks, some strikes resumed, and conditions remain fluid.
The Department of Defense (DOD, which is ""using a secondary Department of War designation,"" under Executive Order 14347 dated September 5, 2025) has not published a comprehensive assessment of combat losses in OEF. During a May 12, 2026, hearing, Acting Pentagon Comptroller Jules W. Hurst III testified that the department's cost estimate for military operations in Iran has increased to $29 billion. "A lot of that increase comes from having a refined estimate on repair or replacement costs for equipment," he said.
Listed here are 42 on September 14, 2026, published a Lead Inspector General (Lead IG) Report to the United States Congress on Operation Epic Fury (OEF), which assessed certain equipment losses relating to operations against Iran between April 1 and June 30. Some analysts and DOD officials have published varying estimates of the cost to replace lost equipment, including aircraft. In September 2026, the Congressional Budget Office (CBO) estimated the cost of equipment losses as of August 1 at between $1.9 billion and $3.3 billion, depending on DOD plans for replacements.
Listed below are 81 fixed-wing or rotary-wing aircraft, including uncrewed aircraft (i.e.,systems (UAS, or drones), reportedly lost or damaged in OEFU.S. operations against Iran since February 28, according to news reports and, statements by DOD and U.S. Central Command (CENTCOM), and the DOD Inspector General (DODIG, which was designated the Lead IG for OEF). The number of aircraft damaged or destroyed may remain subject to revision due to multiple factors, which may include classification, ongoing combat activity, and attribution. Some damaged aircraft may have been returned to active service.

Potential Issues for Congress
These reported incidents may raise several considerations for congressional oversight:
- Information available to Congress.
It is unclear whether DOD has provided Congress an accounting of the aircraft lost in OEF. Congress may assess whether or not it has sufficient information and time to evaluate the potential effects of aircraft damage and losses in U.S. military operations and potential DOD plans or programs to develop or procure replacements.
- Budgetary impacts. Aircraft losses could generate unplanned costs for their replacement, repair, or sustainment. Congress may consider whether or not to approve, reject, or modify potential reprogramming actions or supplemental appropriations or to make adjustments to planned procurement and readiness accounts.
Force sufficiency. It is unclear how the extent of aircraft losses may affect DOD's ability to meet current operational requirements, maintain global force posture, and respond to unforeseen contingencies.acquire replacements.
- Budgetary impacts. Members of Congress may consider whether or not to approve, reject, or modify requests for funding relating to the replacement or repair of aircraft lost or damaged in OEF.
Force sufficiency. Congress may assess whether losses in certain high-demand platforms that are aging and limited in number, such as the E-3 Sentry, create capability gaps or increase risk in other theaters. - Industrial base capacity. Congress may assess whether current production lines and supply chains
are capable of replacingcan replace lost aircraft within time frames needed to meet DOD operational requirements. Congress may seek information about the extent to which competing demands—including foreign military sales or production constraints—may affect DOD's ability to regenerate capacity.
- Operational risk.
Reported losses may provide insights into the survivability of U.S. aircraft in contested environments. Congress may assess whether reported losses reflect changes in the threat environment or in adversary capabilities. Congress may also assess whether any changes to the threat might signal the need to adjust U.S. adjust U.S. equipment; operational concepts,; tactics, techniques, and procedures,; or basing posture.
