The Congressional Research Service (CRS) report said the aircraft losses ranged from advanced F-35 stealth fighters and F-15E Strike Eagles to MQ-9 Reaper drones and KC-135 aerial refuelling tankers. The report added that the overall financial cost of the damaged or destroyed aircraft could exceed $29 billion.

According to Stars and Stripes, the US military lost 24 MQ-9 Reaper drones alone during the conflict. The report also detailed the loss or damage of several manned aircraft, including an F-35A Lightning II reportedly hit by Iranian ground fire, three F-15E Strike Eagles shot down in a friendly fire incident over Kuwait, and multiple KC-135 tankers damaged during Iranian missile and drone strikes on bases in Saudi Arabia.

Questions over transparency and military readiness

The findings have intensified debate in Washington over transparency surrounding the Iran campaign. Lawmakers have pressed the Pentagon for a clearer accounting of military losses and operational readiness after the campaign. The CRS report reportedly relied on Pentagon statements, CENTCOM disclosures and media reports, while cautioning that the numbers could still change because some damage assessments remain classified.

Rising tensions between Washington and Tehran

The controversy comes amid renewed tensions between Washington and Tehran. Iran warned that any fresh US military action could widen the conflict beyond the Middle East. At the same time, US President Donald Trump signalled that Washington was considering further military options if negotiations with Tehran collapsed.

Meanwhile, criticism has also emerged within the US Congress. The New York Post reported that the US Senate recently advanced a war powers resolution seeking to limit further military action against Iran without congressional approval, reflecting growing unease over Operation Epic Fury and its long-term consequences.
