Two reports released last week by the U.S. government shed light officially, for the first time, on the damage Iran has inflicted on the Pentagon’s aerial fleet since the war began almost seven months ago. TWZ has combined their accounting with open-source intelligence (OSINT) reporting and our own tracking to produce a comprehensive graphic visualizing what the U.S. has lost - and what it will cost to replace.

The picture it paints is not a pretty one, with implications should the U.S. trade blows with a peer adversary in the Pacific. In This Article Drone Fleet Takes The Brunt Of The Blow The Crewed Aircraft Tally The True Cost Explained Reports Highlight Strain On America’s Munitions Stockpile The Impact On Deterrence SHOW 2 MORE On September 14, the Pentagon’s Lead Inspector General (IG) released its first quarterly report to Congress on Operation Epic Fury (OEF), which included aircraft casualties suffered by the U.S. from the beginning of the war on February 28, 2026, through June 30.

The Congressional Budget Office (CBO) followed the next day with even more detail, assessing the costs incurred during combat operations against Iran with an overview of aircraft losses through August 1, as well as the estimated replacement cost in 2026 dollars. TWZ went a step further, continuing where both reports left off with the help of the OSINT community, to update our previous visualization and tally losses through September 18, incorporating damage from attacks by the Islamic Revolutionary Guard Corps (IRGC) on American bases in the Middle East over the past two months.

The final accounting can be viewed in the high-definition graphic below. TWZ/IAN ELLIS-JONES Drone Fleet Takes The Brunt Of The Blow America’s MQ-9 Reaper drone fleet has absorbed the bulk of the damage and accounts for the largest single line-item expenditure in the CBO’s letter to the ranking member of the House Budget Committee.

According to the Lead IG, “as many as 30” MQ-9A Reaper drones were destroyed in “various circumstances,” while the CBO booked 24 at a unit cost of $30 million (based on the Foreign Military Sales program), which totals $720 million to $900 million in lost equipment. The cost of a fully kitted-out Reaper can approach $50 million, depending on the sensors, weapons, and other mission equipment it carries.

The Air Force Chief of Staff, Gen. Kenneth Wilsbach, told the House Armed Services Committee in May that the Reaper was the war’s “most valuable player.” But both numbers are stale. The Washington Post reported in August that at least 45 Reapers, approximately a quarter of the pre-war fleet, were shot down, crashed, or destroyed on the ground, citing three U.S. officials familiar with the matter.

That figure covers MQ-9s lost across the Middle East, including those downed over Iran and by the Houthis in Yemen. The Air Force is on record admitting that the Reaper fleet shrank to 135 airframes as of May, down from an official total of 165 at the start of fiscal year 2026. Another two have been shot down since the Post’s report, according to open-source intel, bringing the total to 47, or more than $1.4 billion based on the CBO’s methodology.

While every Reaper lost is expensive, in some cases at least, each would represent a soul, or crew, that may have been at risk in a previous era’s conflict, and no dollar figure captures that trade-off.

Photo: USAF General Atomics’ iconic MQ-9A is no longer in production, and the service does not view the newer, in-production MQ-9B as a platform to meet its current needs and cost demands.

Instead, it is targeting a replacement with a unit cost of around $10 million (excluding sensors) and pushing to accelerate the program to acquire these lower-cost platforms, dubbed the Massed Modular Aircraft (MMA). “If you don’t like losing an MQ-9A that cost on the order of $50 million, with the sensors, you’re probably not going to like losing an MQ-9B at a higher price point,” Lt.

Gen. Christopher Niemi, the Air Force’s Chief Modernization Officer, said at a roundtable in September, according to a report from Air & Space Forces Magazine. In June, the USAF confirmed to TWZ that after a relatively frantic hunt for additional airframes, it was planning to purchase a number of unused Reapers from General Atomics, which turned out to be fewer than 10.

There is no easy answer to this problem, as cheaper alternatives cannot replace all the capabilities provided by pricier platforms. There are several more attritable alternatives in development, such as the General Atomics Wildfire, which the company is building specifically to meet the needs outlined in the MMA program.

An MQ-4C Triton went down over the Persian Gulf in April after squawking a lost-link code and general emergency on its way back to Naval Air Station Sigonella in Italy. The Navy logged it as a Class A mishap and the cause remains unknown. There are only 20 in the fleet, and at $150 million a pop, the loss represents a significant outflow.

Navy budget documents place the unit price higher at $238 million. And, in late May, U.S. Central Command (CENTCOM) announced that Iran shot down an MQ-1 over international waters.

CENTCOM declined to tell TWZ whether it was an Air Force Predator, which is officially out of service, or an Army Gray Eagle platform, and neither appeared in the government reports. The Crewed Aircraft Tally In terms of manned aircraft, the KC-135 Stratotanker fleet took the biggest hit. The workhorse aerial refueling tanker is primarily tasked with keeping America’s fighters, bombers, and cargo haulers airborne, and crews have been flying nearly nonstop sorties to support active operations in the CENTCOM area of responsibility (AOR).

Two were destroyed and up to seven have been damaged, although the Air Force has become relatively efficient at repairing the damaged aircraft enough to fly them home. In a tragic incident on March 12, a collision between two Stratotankers that was “not due to hostile fire or friendly fire,” according to CENTCOM, resulted in the loss of six airmen after one of the aircraft went down over western Iraq.

Photo: Andrew McKelvey Three F-15E Strike Eagles were destroyed early in the conflict due to friendly fire over Kuwait, and one was shot down over Iran on April 3, leading to a massive combat search and rescue (CSAR) operation. “Roughly eight” more were damaged in a recent salvo of ballistic missile fire on Muwaffaq Salti Air Base in Jordan, first reported by CBS News and confirmed by Air & Space Forces Magazine, both citing unnamed U.S. officials.

President Donald Trump dismissed the reports, telling NewsNation there was “no damage, no nothing.” The daring CSAR mission to save the two F-15E crew members who ejected inside Iran, one of whom 60 Minutes interviewed on September 13, took place between April 3 and 5. While no American lives were lost during the operation, several aircraft were destroyed, including two MC-130J Commando IIs and four Night Stalker MH-6 Little Bird helicopters (which TWZ was first to report), representing, at north of $400 million, the costliest single operation of the war for aircraft inventory.

The mission reportedly included more than 150 aircraft and 92 special operators on the ground deep in enemy territory. The MC-130Js became stuck on a temporary remote airstrip and were deliberately destroyed by American forces to prevent capture, along with the Little Birds operated by the 160th Special Operations Aviation Regiment (SOAR).

An HH-60W Jolly Green II was also struck but continued flying. The CBO booked the MC-130Js at $300 million, and the five helos at $122 million. Two A-10C Warthog close air support jets also took hits.

The first, while flying in a “Sandy” escort role during the rescue operation, was hit by enemy fire. “This pilot continued to fight, continued the mission, and then upon exit, flew his aircraft into another country and determined that the airplane was not landable,” Chairman of the Joint Chiefs of Staff, Gen. Dan Caine, said during a presser in April. “The pilot then made the decision to eject over friendly territory, and was quickly and safely recovered.” The second Warthog sustained damage on the ground in Jordan during the IRGC’s latest round of strikes referenced above.

The jet, serial number 81-0005, was struck on the taxiway at Prince Sultan Air Base in Saudi Arabia on March 27, one of just 16 Sentries the service had left after initially deploying six to the theater before the conflict kicked off. The IG report lists it as damaged, but that is generous, considering that photographs and satellite imagery show the plane cut in half with the rear fuselage destroyed.

The CBO report is more candid, categorizing the Sentry as lost in battle and assigning a $500 million replacement value. The Pentagon tried to cancel the E-7 program last year, but has since reversed course, after Secretary Pete Hegseth said the department’s mindset “completely changed.” GOOGLE EARTH/USAF (COMPOSITE IMAGE) A handful of other hits round out the tally.

A 5th-generation F-35A Lightning II Joint Strike Fighter (JSF) was struck by Iranian fire in mid-March and forced to make an emergency landing. As far as we know, this was the first time an F-35 took hostile fire in combat. The following week, a first-person-view (FPV) short-range kamikaze drone successfully targeted a U.S.

Army Black Hawk parked at a base outside Baghdad, Iraq. The next month, images circulated by Iranian state media, which TWZ did not independently verify, showed a CH-47F Chinook wrecked on the ground at Camp Buehring in Kuwait. And, in June, an AH-64 Apache was shot down near the Strait of Hormuz.

Recent retaliatory attacks by IRGC forces on U.S. bases have damaged additional aircraft in the weeks following the CBO’s cutoff date. Another four helicopters were hit since September 10, @DefenceGeek, a UK-based OSINT researcher and flight tracker, told TWZ. His team at @MATA_osint reviewed open-source videos and identified them as H-60 models, likely UH-60M/L variants.

The True Cost Explained Through August 1, the CBO estimated that the losses represented nearly $1.9 billion in 2026 dollars, but that figure only counts hardware the Pentagon “would have to change its plans to replace.” If the department sought funding to replace everything it lost with platforms available today, the true cost rises to $3.3 billion.

For example, the A-10C Warthog is no longer being built, and the CBO assesses that if it were to be replaced with an F-35A instead, the price balloons from $0 to $120 million. Similarly, since the F-15E has no active production line, the replacement cost of four F-15EX would total $400 million, compared to $0 on paper.

The CBO figure also includes a $500 million charge for a lost THAAD AN/TPY-2 radar, a prized air defense asset, one of only eight radars the Army has for its THAAD batteries. It is (obviously) not an aircraft but counted in the report’s accounting. Taking into consideration the losses suffered since the CBO’s assessment on August 1, and the cost to repair damaged aircraft, which is not included in the table above, the $3.3 billion figure could top $4 billion.

Additionally, CENTCOM told the IG that “hundreds of buildings and structures” were damaged and destroyed at various bases across the AOR, in addition to miscellaneous equipment, sensors, and other installations that...
