TEHRAN – The aviation losses sustained by U.S. forces since February 28 have become one of the clearest indicators of the operational pressures facing American and allied airpower in the Persian Gulf. 

While U.S. officials have offered differing explanations for each incident, the cumulative record — as reported by American and international media — shows that U.S. and Israeli aircraft have faced significant attrition during the confrontation. These losses, spanning refueling aircraft, fighter jets, drones, and advanced stealth platforms, underscore the risks of operating near a capable and increasingly assertive regional military power.

One of the most consequential incidents was the destruction of a KC‑135 Stratotanker in Iraq, which resulted in the deaths of six crew members. Although the United States maintains that the aircraft was not downed by hostile fire, the loss occurred during a period of intense regional pressure in which U.S. aerial operations were stretched across multiple theaters. A second KC‑135 involved in the same event sustained damage before landing safely, further illustrating the strain placed on U.S. refueling operations. Additional refueling aircraft were also affected elsewhere in the region: according to reporting by the Wall Street Journal, five U.S. KC‑135 tankers stationed at Prince Sultan Air Base in Saudi Arabia were damaged during an Iranian missile strike. While most were eventually returned to service, the incident demonstrated Iran’s ability to threaten high‑value U.S. assets even at fortified bases.

Further losses included three F‑15 Strike Eagles in Kuwait, which U.S. officials attributed to friendly fire. Regardless of the explanation, the incident occurred amid heightened alert levels and rapid‑response operations triggered by the regional confrontation. The destruction of three advanced fighter aircraft in a single event highlights the operational pressures facing U.S. aircrews during this period.

Unmanned systems have also suffered heavy attrition. At least 10–12 MQ‑9 Reaper drones were destroyed or damaged, many of them shot down by Iranian air defenses, with others lost to accidents or missile strikes on regional airfields. These losses have reduced U.S. surveillance and strike capacity at a time when persistent intelligence coverage was essential to regional operations. 
A U.S. F‑35 stealth aircraft was forced to make an emergency landing after sustaining damage believed to have been caused by Iranian fire. U.S. officials acknowledged the aircraft was struck during operations. The temporary loss of an F‑35 — one of the most advanced aircraft in the U.S. arsenal — represents both a symbolic and practical setback for American airpower.

Israel has also sustained aviation losses during the confrontation. Early OSINT assessments confirmed the destruction of at least one Israeli drone during the initial exchange of strikes between Israel, the United States, and Iran. This occurred amid large‑scale Iranian missile and drone attacks targeting Israeli military infrastructure, demonstrating that Israeli unmanned platforms were not immune to the expanding threat environment.

Collectively, these aviation losses — including refueling aircraft, fighter jets, drones, and a fifth‑generation stealth platform — reveal the extent to which U.S. and Israeli air operations have been challenged during the confrontation. The regional environment shaped by Iran’s expanding military capabilities has imposed operational risks that cannot be fully mitigated by technology or defensive systems.
