A Pentagon watchdog has revealed that the United States lost dozens of aircraft, including at least 30 MQ-9 Reaper drones, and that hundreds of buildings and structures used by the US were damaged or destroyed by Iranian attacks during the conflict.
The report published on Monday by the Department of Defense
inspector general offers the first official account of the losses Washington
has incurred in the war from 28 February to 30 June.
Moreover, the report acknowledges that the US is running
short on its munition stockpile and facing “bottlenecks” in supply chains,
contradicting President Donald Trump’s repeated pushback. On Monday, Trump said
the US is producing “more Exquisite and Elite Weapons than at any time in our
History”. Previously, he asserted that the US has “virtually unlimited”
ammunition after reports of shortages by the US media.
An estimated $22bn was spent on expended munitions between
28 February and 30 June during Operation Epic Fury (the name of the US military
operation), the report said, adding that the war has cost $33bn during the same
period.
Throughout the war – beginning with the US-Israel attacks on
Iran in late February – Tehran has routinely bombed US bases and assets in the
Gulf region. For most of those attacks, Gulf countries and Washington said the
incoming strikes had been intercepted and thwarted.
But the Pentagon’s report paints a picture of significant
damage and losses running into millions of dollars to US forces and facilities
in the region, far more than previously acknowledged.
Currently, the US and Iran are locked in a diplomatic
deadlock, with the Strait of Hormuz, a global oil chokepoint, remaining almost
entirely blocked.
So, what losses has the US incurred in its war on Iran?
How many US personnel
were killed?
The Pentagon’s report says the Defense Department has
reported that at least 11 US military personnel were “killed in action”, while
seven died in “non-hostile events” during the war.
At least six were killed at Kuwait’s Port Shuaiba on 1
March; one in Saudi Arabia on the same day; three at Jordan’s Muwaffaq al-Salti
airbase, or the Al Azraq base, on 17 July; and one at Iraq’s Erbil airbase on
19 July, in Iranian attacks.
The report added that at least six personnel were killed
after a premier jet-powered aerial refuelling tanker KC-135 crashed in Iraq on
12 March, while another was killed after an MH-60S helicopter crashed in the
Arabian Sea on 1 July.
These killings were already public.
The mandatory report to the US Congress added that at least 417 US military personnel were wounded in Iranian attacks until 30 June.

How many aircraft did
the US lose?
The US losses covered everything from front-line fighters
and attack aircraft to aerial-refuelling tankers, airborne command-and-control
planes, rescue helicopters, and unmanned surveillance aircraft.
F-15E: At least four of these two-seat $30m fighter jets
were destroyed. Three of these twin-engine fighter-bombers used for
air-to-ground strikes as well as air-to-air combat were shot down by friendly
fire over Kuwait on 1 March. A fourth was shot down during combat over Iran in
April. All aircrews were recovered.
F-35A: At least one of the US’s prized stealth multirole fighters, designed to penetrate heavily defended airspace, was damaged in Iranian fire in March.
A-10: At least one of the heavily armoured ground-attack
aircraft, designed primarily to provide close air support to troops on the
ground, was shot down by Iranian fire.
KC-135: At least seven of these large aerial-refuelling
tankers, which extend the range and endurance of US combat aircraft, were
damaged or destroyed. One crashed in Iraq on 12 March during a refuelling
mission, killing all six crew members; five others were damaged on the ground
by Iranian missiles and drones in Saudi Arabia. A seventh aircraft was also
involved in the Iraq incident and is included in the broader loss count.
E-3 Sentry: At least one of these airborne early-warning and
control aircraft was damaged on the ground at Saudi Arabia’s Prince Sultan
airbase in a subsequent Iranian strike.
HH-60W helicopter: At least one of these four-blade,
twin-engine, medium-lift utility military helicopters was damaged by Iranian
fire during a combat search and rescue mission.
MQ-4C Triton: At least one of these $240m high-altitude,
long-endurance unmanned surveillance aircraft, designed primarily for maritime
intelligence and surveillance, crashed in April.
AH-6 helicopter: The US forces destroyed four of these
small, highly manoeuvrable helicopters after they were deemed unrecoverable
during a combat search and rescue operation in Iran.
AH-64 Apache: At least one of these twin-engine, four-bladed
attack helicopters, built with a tandem cockpit for a crew of two, was shot
down near the Strait of Hormuz on 8 June.
MH-60S: At least one of these US Navy multi-role helicopters
crashed in the Arabian Sea on 1 July. Three of the four crew were wounded and
rescued, while the fourth was listed as missing.
MQ-9 Reaper: As many as 30 of these long-endurance armed unmanned aircraft used for surveillance, intelligence gathering, and precision strikes were destroyed.
The Iranian military has claimed to have inflicted further
damage on US assets, shooting down surveillance and attack drones near the
Strait of Hormuz several times. Tehran also captured a US submersible Dive-LD
earlier this month.
What losses did US
military bases suffer in the region?
The report further underlined the assertion by the US
Central Command (CENTCOM) that Iranian attacks damaged and destroyed hundreds
of buildings and structures at US military installations in Kuwait, Bahrain,
Qatar, UAE, Saudi Arabia, Iraq, Oman, and Jordan during the conflict.
It did not provide any additional detail or specifics on
these damages.
From previous reporting, we know that several US facilities
were temporarily shut down or moved due to Iranian attacks.
The report noted that the “establishment of adequate naval
bases and support ports posed significant challenges before and during” the US
military campaign against Iran, “arising from complexities and due to uncertainties
with host nation access permissions to utilize ports for fleet resupply”.
“An issue with shifting logistics support and infrastructure
to Diego Garcia has been distance, with extended sea transit requiring 14- to
18-day logistics cycles,” the report quoted CENTCOM as saying.
How Iranian attacks
damaged US diplomatic facilities in the Gulf
The watchdog’s report noted that the US diplomatic
facilities in four countries: Iraq, Kuwait, Saudi Arabia and the UAE, suffered
damage from Iranian attacks, with an estimated total cost of $184m.
In addition, Washington incurred an estimated cost of $24.5m per month in construction project delays due to ordered departures and travel restrictions in Baghdad, Jerusalem, Tel Aviv, Cairo, Amman, Kuwait City, and Muscat.
Iraq
The report quoted the US Department of State as saying the
Iraq mission faced more than 600 attacks until the end of June, costing up to
nearly $157m.
The US Consulate General in Erbil’s new consulate compound
suffered damage to multiple buildings. The US Embassy in Baghdad suffered
damage “but to a lesser extent”, the report said, adding that the Baghdad
Diplomatic Support Center, located near Baghdad International Airport, suffered
extensive damage.
Kuwait
On 5 March, the US Embassy in Kuwait City suspended
operations due to “regional tensions”, attacks, and damage to embassy
facilities, the report said, costing nearly $14.75m.
Saudi Arabia
On 3 March, two Iranian drones struck the US Embassy in
Riyadh, causing material damage, costing about $11.5m.
UAE
The US Consulate General in Dubai sustained damage to a
utility building, the US State Department reported, costing nearly $120,000.
