Recent steep losses of U.S. military aircraft during joint U.S.-Israeli operations in the Middle East have ignited urgent new debate over whether American air power can endure sustained high attrition in a potential future great-power conflict against China in the Indo-Pacific.
In May 2026, the nonpartisan U.S. Congressional Research Service (CRS) published a detailed report documenting that at least 42 U.S. aircraft have been lost or damaged beyond field repair since the launch of Operation Epic Fury, the February 2026 U.S.-Israeli military campaign targeting Iranian military and infrastructure assets. The toll cuts across every major segment of U.S. air power: fighter jets, refueling tankers, special operations aircraft, helicopters, and uncrewed surveillance and strike drones, painting a stark picture of the campaign’s high intensity.
A breakdown of the confirmed losses includes four F-15E Strike Eagle fighters—three destroyed in friendly fire incidents over Kuwait in March, and a fourth shot down over Iranian airspace in April—plus one damaged F-35A stealth fighter, one A-10 Thunderbolt II destroyed by enemy fire, seven KC-135 refueling tankers, one E-3 Sentry AWACS early warning aircraft, two MC-130J special operations transport aircraft, one HH-60W combat rescue helicopter, 24 MQ-9 Reaper strike drones, and one MQ-4C Triton surveillance drone. Several additional aircraft were damaged on the ground at Saudi Arabia’s Prince Sultan Air Base during Iranian missile and drone counterattacks, while the two stranded MC-130Js inside Iranian territory were deliberately destroyed by U.S. forces to prevent capture.
The CRS notes that the U.S. Department of Defense has not publicly released a full official damage assessment, but Capitol Hill lawmakers are already preparing to investigate the wide-ranging operational, budgetary, and defense industrial base implications of replacing these high-value military aircraft. Analysts have attributed the heavy losses to a mix of overlapping factors: tactical mistakes on the battlefield, surprisingly resilient Iranian air defense networks, long-unaddressed vulnerabilities in U.S. operational doctrine, and improved Iranian strike capabilities backed by technical and intelligence support from China and Russia.
Writing for Forbes in March 2026, defense analyst Peter Suciu argued that common fog-of-war challenges contributed heavily to avoidable losses. These include ground crew and pilot errors caused by turned-off emitters or transponders during covert operations, widespread communications overload from constant radio traffic, disruptive enemy electronic warfare, rapidly shifting operational plans, failures in data linking and digital command systems, and human factors such as stress, fatigue, and inadequate training for high-intensity combat. Dense multinational operating environments, conflicting radar readings, unrecognized identification friend-or-foe (IFF) system failures, and pilots forgetting critical combat procedures have also amplified avoidable losses, Suciu added.
Beyond tactical missteps, analysts emphasize that even after months of preliminary strikes, Iran’s integrated air defense network has retained enough operational capacity to impose heavy costs on U.S. air operations. Ahead of Operation Rising Lion—Israel’s June 2025 pre-emptive strikes on Iran’s nuclear program, widely seen as the precursor to February 2026’s Operation Epic Fury—defense journalist Arie Egozi documented that Iran operated a layered, multinational air defense architecture including Russian TOR-M1, SA-5, SA-6, and S-300PMU systems, Chinese-designed HQ-2 and FM-80 batteries, upgraded legacy HAWK missiles, British Rapier systems, and Swedish RBS-70 short-range weapons.
Per Egozi’s analysis, the Russian-built TOR-M1 is capable of engaging fixed-wing aircraft, helicopters, drones, guided missiles, and precision-guided ordnance even in heavily contested electronic warfare environments, while the S-300PMU forms the backbone of Iran’s long-range defense capability, with advanced multi-missile compatibility, extended range, and improved lethality. Iran has also integrated Chinese-built YJ-14 search radars, modernized air surveillance systems, and a unified command-and-control network to protect key national assets including Tehran, military sites, port facilities, and oil infrastructure.
While U.S. and Israeli strikes did degrade Iran’s largest fixed-site air defense systems such as the S-300PMU, hundreds of mobile, concealed, and dispersed short-range systems survived pre-emptive attacks and continue to pose a major threat to coalition aircraft. Lower-cost, highly portable systems have proven particularly difficult to suppress. The Robert Lansing Institute (RLI) reported in February 2026 that under a €500 million contract signed in December 2025, Russia agreed to supply Iran with 500 Verba man-portable air defense systems (MANPADS) and 2,500 9M336 missiles for delivery between 2027 and 2029. The RLI notes that Verba MANPADS are optimized to engage low-flying aircraft, helicopters, cruise missiles, and drones, and their widespread deployment across Iran has already significantly complicated U.S. air operations, increased attrition risk for low-altitude airframes, and forced coalition aircraft to alter flight routes, cruising altitudes, and mission timelines. MANPADS deployed around high-value Iranian sites also create localized no-fly zones that hinder intelligence, surveillance, and reconnaissance (ISR) operations, combat search and rescue (CSAR) missions, and rapid strike sorties.
The heavy attrition experienced during Operation Epic Fury has also exposed critical gaps in the U.S. military’s core operating doctrine for high-intensity conflict, the Agile Combat Employment (ACE) framework. As analyst Michael Blaser outlined in a 2024 Proceedings article, ACE is designed to increase aircraft survivability by dispersing airframes across multiple small bases and relocating them frequently to outpace enemy targeting cycles. However, Blaser argues that this strategy relies on two unrealistic assumptions: that adversaries lack the long-range strike capacity to hit dozens of dispersed airfields simultaneously, and that enemy kill chains—the sequential process of identifying, tracking, and attacking targets—will remain slower than the U.S. military’s ability to generate sorties and relocate aircraft.
The CRS report’s documentation of six U.S. aircraft destroyed on the ground at Prince Sultan Air Base by Iranian counterstrikes—five KC-135 tankers and one E-3 AWACS—directly illustrates this vulnerability. Blaser adds that modern artificial intelligence, machine learning, and persistent space-based surveillance have cut adversary kill chains to less than 24 hours, allowing peer competitors to identify and target dispersed U.S. aircraft faster than U.S. crews can relocate them to new positions.
These doctrinal and operational vulnerabilities have been further exacerbated by alleged intelligence and targeting support provided to Iran by China and Russia. The report notes that China has supplied Iran with commercial satellite imagery, access to ground receiving stations, and AI-powered intelligence tools that can process satellite data, flight tracking, and commercial shipping information to identify U.S. deployments. Chinese private firms have also used AI-enabled open-source intelligence (OSINT) to map U.S. force positions and reconstruct coalition flight patterns. Russia, meanwhile, has reportedly provided Iran with its own satellite imagery, real-time targeting data, and ISR support tracking U.S. troops, warships, and aircraft, enabling far more precise Iranian strikes on U.S. radar sites, command infrastructure, and forward positions. Together, this support has helped Iran build a distributed, plausibly deniable intelligence network that underpins its most effective counterstrikes.
The strategic implications of these losses extend far beyond the Middle East, directly shaping U.S. military planning for a potential future conflict with China in the Pacific. Unlike Iran, China fields a far larger, more capable missile arsenal, has a much deeper defense industrial base, and operates a far denser integrated strike network across the Indo-Pacific.
A 2023 report from the Center for Strategic and International Studies (CSIS) led by analyst Mark Cancian already warned that the U.S. and its regional allies could lose hundreds of aircraft in a conflict over Taiwan, with 90% of those losses occurring on the ground to pre-emptive Chinese missile strikes. The report attributed these projected losses to China’s large, sophisticated arsenal of ballistic and cruise missiles, which can target the small number of fixed air bases available to U.S. forces across the Western Pacific.
If the heavy attrition seen in Operation Epic Fury is any indication, future conflicts against peer great-power competitors will not be decided by which side fields the most technologically advanced stealth fighters. Instead, victory will likely go to the power that can keep enough of its air fleet dispersed, survivable, and operational through weeks of sustained missile and drone attacks.
