The United States military lost, damaged, or destroyed 42 aircraft during combat operations in Iran [1].

These losses occurred during Operation Epic Fury, a campaign that has tested U.S. aerial capabilities. The disclosure follows reports that the Pentagon has not publicly detailed the extent of these losses, leaving the U.S. Congress to provide the figures [1].

The aircraft lost include various fighter jets and other military planes [3]. The specific types of aircraft lost reflect the intensity of the engagement in Iranian airspace, where U.S. forces have faced sustained opposition since the start of the conflict.

Financial estimates for the replacement of these assets vary significantly across reports. One estimate places the total replacement cost at $29 billion [2]. However, another report suggests a much lower figure of $2 billion [4].

These figures highlight the scale of attrition experienced during the campaign. The discrepancy in cost estimates may stem from differing valuations of specific airframes, or the inclusion of associated equipment and infrastructure.

Operation Epic Fury continues to be a focal point of U.S. military strategy in the region. The loss of 42 aircraft as of May 2026 underscores the risks associated with the current operational environment in Iran [2], [3].

The gap between Congressional reports and Pentagon disclosures suggests a tension regarding transparency in wartime attrition. Furthermore, the massive variance in replacement cost estimates, ranging from $2 billion to $29 billion, indicates uncertainty in how the financial impact of Operation Epic Fury is being calculated or reported to the public.
