Eighteen American service members died in Operation Epic Fury, and 417 were wounded in action through June 30. Those are the first numbers in the Pentagon watchdog’s first official accounting of the Iran war, published Monday, and they are the ones to sit with before anything else in it.

The hardware column is where the drone story is. The Department of War inspector general, writing as Lead Inspector General for the operation, counts as many as 30 MQ-9 Reapers destroyed between February 28 and June 30. That is more than every crewed aircraft loss in the report put together, and it is six more than the 24 DroneXL counted in April.

The watchdog puts the operation’s cost at $33.4 billion as of June 29, including $22.3 billion in expended munitions and $3.7 billion in equipment losses, with infrastructure repairs excluded because nobody has decided yet what the rebuilt bases will look like.

The Casualty Table Comes Before the Aircraft Table

Eighteen Americans died. The casualty table records six killed at Kuwait’s Port Shuaiba on March 1, one in Saudi Arabia that day, six in a KC-135 collision over Iraq on March 12, and five more in July in Jordan, Erbil and the Arabian Sea.

Seven of those deaths are logged as killed in action inside the reporting window, seven as non-hostile, and four more as killed in action in July. There is a bookkeeping detail underneath that split: the Defense Casualty Analysis System counts everything before July 7 as Operation Epic Fury and everything after it as “overseas operations,” which means the war’s running total now lives in two places.

Reaper Losses Outnumber Every Crewed Aircraft in the Table

Twenty-one crewed airframes were destroyed or damaged, by the report’s own count: four F-15Es, one F-35A, one A-10, seven KC-135s, one E-3 Sentry, one HH-60W, four AH-6s, one AH-64 Apache and one MH-60. The uncrewed column lists 31 aircraft on its own.

Three of the four F-15E Strike Eagles were downed by friendly fire, the fourth by enemy fire. Five of the KC-135 tankers were hit on the ground in Saudi Arabia by Iranian munitions, and the E-3 Sentry was damaged where it sat, also on a Saudi ramp. The report gives no date or location for the single MQ-4C Triton it lists as crashed, seven months after a Triton vanished from radar near Iran on February 22 while flying out of Al Dhafra.

At roughly $30 million an airframe, the arithmetic DroneXL used in April to reach $720 million for 24 Reapers now runs closer to $900 million. The Air Force’s own number is higher: Lt. Gen. Christopher Niemi told senators in May that a Reaper with a full sensor package can cost up to $50 million.

The Report Never Explains How the Reapers Died

Table 5 disposes of the war’s largest loss in eight words: “As many as 30 destroyed in various circumstances.” No split between shoot-downs and aircraft caught on the ground, no count of link failures, no mention of jamming. The footnote credits CRS and a CENTCOM vetting comment.

That gap matters because the cause determines the fix. A Reaper killed by a Bavar-373 battery is an argument about survivability in contested airspace. A Reaper lost when its satellite link dropped is an argument about electronic warfare, and the two lead to different aircraft and different budgets. CENTCOM has not published the split, and the classified appendix that accompanies the report is not going to settle it for the rest of us.

The number itself is also the conservative one. The Washington Post reported on August 13, citing three US officials, that at least 45 Reapers had been lost, roughly a quarter of the fleet, a figure Air Force Times carried alongside the service’s replacement plans. The inspector general’s count stops on June 30 and the fighting did not.

Iranian Attack Drones Hit Embassies and Moved a Navy Hub

Two Iranian one-way attack drones struck the US Embassy in Riyadh on March 3, causing about $11.5 million in damage and a shelter-in-place order across three Saudi posts. Diplomatic damage in Iraq, Kuwait, Saudi Arabia and the UAE totals roughly $184 million.

Iran also aimed one-way drones and ballistic missiles at Bahrain, and the Shahed strikes that reached Bahrain and Kuwait pushed US Naval Forces Central out of its main Gulf logistics hub. The replacement arrangement runs through Diego Garcia on 14- to 18-day resupply cycles, which is how a cheap airframe rearranges a fleet’s supply chain without sinking anything.

The defensive side of that ledger is the one nobody publicizes. The regional integrated air-defense network intercepted more than 6,000 one-way drones and more than 1,500 ballistic missiles aimed at US and partner forces, on top of the Iranian drones CENTCOM shot down over the Strait of Hormuz in June. Read the loss table against that interception count and the picture is a defense that mostly held while the ISR fleet burned down anyway.

Congress Is Being Asked for $2.4 Billion in Drones

The White House sent Congress an $87.6 billion supplemental request on June 24, of which $67.1 billion goes to the Department of War. Unmanned aircraft systems get their own $2.4 billion line, cybersecurity and autonomy get $5.1 billion, and munitions take $21 billion of the total.

Gulf partners are buying the other half of the problem. The UAE cleared $2.1 billion for a fixed-site system built to defeat low, slow and small drones, and Kuwait bought $2 million in counter-drone platforms, both through emergency or routine arms sales notified between March and June. Ukraine-built interceptors were already flying at US bases in Jordan in March.

The watchdog has one counter-drone project open, and its subject is telling: an evaluation of whether the Pentagon’s counter-UAS systems can work together at all, and what it would take to standardize them. That audit was announced with no completion date attached.

DroneXL’s Take

The Reaper did what it was built to do, and Niemi is right that its speed and altitude are decades-old technology carrying a sensor package that isn’t. His line to reporters on September 3: “we are going through them at a rate that is concerning to us.”

That is a general saying the quiet part in budget language. What the report documents underneath it is harder: a single mid-tier adversary with Russian-derived air defenses and working electronic warfare removed more American uncrewed aircraft in four months than every crewed loss combined, and there is no factory to call. General Atomics shut the MQ-9A line in 2025. The usable fleet was down to about 135 airframes when Lt. Gen. David Tabor testified in May, against a stated floor of 189. You cannot buy your way out of an attrition problem with a catalog that no longer has the item in it.

My read is that the Massed Modular Aircraft program is now the most consequential drone procurement in the US, and almost nobody outside the trade press is watching it. The Defense Innovation Unit opened it on July 7 and closed submissions on July 23. Air Force officials have said concept-refinement awards are expected in the first quarter of fiscal 2027, which starts next month, and Air Force Secretary Troy Meink has directed an acceleration that could pull the fiscal 2031 fielding target forward by about two years.

Watch two things after that. The next quarterly Lead IG report covers July through September, the period when strikes resumed and four more Americans were killed in action, and it will show whether the Reaper number keeps climbing toward the Washington Post’s 45. And watch whether anyone in that MMA competition commits to a price with the sensors included, because $10 million for an air vehicle and $50 million for a mission-ready aircraft are not the same claim, and the second one is what actually flies.
