Operation Epic Fury
US–Iran War Timeline
A single chronological record of the 2026 US-Iran war — Operation Epic Fury — merging war-cost milestones, casualty events, and ceasefire developments into one newest-first timeline.
The 2026 US-Iran war — code-named Operation Epic Fury — began on Feb 28, 2026, when joint US and Israeli strikes hit Iranian military and nuclear installations. Supreme Leader Ali Khamenei was killed in the opening salvo, along with the IRGC commander-in-chief, the armed forces chief of staff, and dozens of senior officers. Iran retaliated within hours with hundreds of drones and ballistic missiles, and the IRGC announced the closure of the Strait of Hormuz to US- and Israel-allied shipping — triggering a global oil-price spike that would shadow the rest of the conflict.
The war moved through distinct phases. The first six days were the costliest: roughly $1.88 billion per day in stand-off munitions and interceptors, with CSIS pegging the first 100 hours at $3.7 billion. As the US established air dominance and shifted from $3.5M Tomahawks to $80K JDAMs, the daily rate fell to about $500M through Day 39. Strikes on the Natanz nuclear facility, the killing of IRGC naval commander Alireza Tangsiri, and Iranian retaliation against the Dimona research center marked the peak of direct hostilities. By the time fighting paused, the Pentagon comptroller had placed direct costs at $29 billion — with $24 billion attributed to repairing or replacing the 42 US aircraft the Congressional Research Service catalogued as lost or damaged.
A Pakistan-brokered ceasefire took effect on Apr 8, 2026, but it was violated within hours and has held only in a contested form ever since. Trump extended the cessation indefinitely on April 21 and declared hostilities "terminated" in a May 1 War Powers letter, yet US and Iranian forces have continued to exchange fire across the Strait of Hormuz — the US striking Qeshm Island and Bandar Abbas, Iran seizing cargo vessels and striking Gulf states including a June 3 drone attack on Kuwait International Airport. The Lebanon theater escalated into a separate war with thousands of casualties. Meanwhile the human cost mounted: 13–15 confirmed US KIA, disputed Iranian military deaths ranging into the thousands, and more than 3,500 Lebanese civilians killed.
The timeline below merges every dated milestone from our three trackers — war cost, casualties, and the ceasefire status tracker — into one chronological view, newest first. Each entry is tagged by category. Only events that appear in those sourced trackers are included; nothing here is invented.

Iran strikes Kuwait airport (1 killed, 63 wounded); US strikes Qeshm Island
Iranian drones struck a passenger terminal at Kuwait International Airport, killing one Indian national and wounding 63, briefly closing the airfield. Kuwait's army intercepted 13 ballistic missiles and 17 drones in the same barrage. Kuwait expelled two Iranian diplomats. Iran also struck Bahrain with drones and three missiles on the same day; Bahrain MoD confirmed it responded but reported no casualties. Concurrently, the US carried out "self-defence" strikes on Iran's Qeshm Island; Iranian media confirmed explosions. Lebanon saw at least 9 killed in Israeli strikes on June 3, including two paramedics, as the death toll continued to climb. (NPR Jun 3 / The National Jun 3 / Al Jazeera Jun 3 / CNN Jun 2–3)
Iran attacks Kuwait airport (1 dead, 63 wounded); CENTCOM strikes Qeshm; House passes war powers 215-208
CENTCOM strikes an Iranian military ground control station on Qeshm Island. Iran retaliates with approximately 30 ballistic missiles and drones targeting Kuwait and Bahrain — IRGC claims to have struck the US Fifth Fleet headquarters in Bahrain and Ali Al-Salem Air Base in Kuwait, both denied by CENTCOM. A drone hits Kuwait International Airport, killing one Indian national and wounding 63 others; the airport briefly closes. Kuwait expels two Iranian embassy staff and "reserves the right to respond." UAE urges unified Gulf opposition. Separately, the US House passes a war powers resolution 215-208 (four Republicans joining all Democrats) directing Trump to end hostilities with Iran — the first such measure to clear either chamber; faces likely presidential veto. Trump says negotiations have gone "very well" and a deal could come "over the weekend."

Iran suspends nuclear talks; IRGC threatens Hormuz and Bab el-Mandeb
Iran suspended its exchange of texts with the US on June 1 in protest of Israel's expanding ground and air offensive in Lebanon. IRGC simultaneously threatened shipping in the Strait of Hormuz and Bab el-Mandeb, and Iranian state media reported Tehran was preparing to fully close Hormuz. Foreign Minister Araghchi said there had been no "significant progress" in recent days; Trump insisted talks had gone "very well." Iran's position: war ends only "when it also ends in Lebanon." Brent crude rose ~5% on the day, trading near $95/bbl intraday. (GlobalSecurity Day-95 Jun 2 / Al Jazeera Jun 3 / CNN Jun 1)
Iran suspends talks citing Lebanon; IRGC strikes Sirik Island, claims US airbase retaliation; Brent spikes
Iran formally suspends ceasefire text exchanges with the US, protesting Israeli strikes on southern Beirut and stating it will not return to talks until Lebanon hostilities stop. The IRGC attacks a US military communications tower on Sirik Island in the Strait of Hormuz and separately claims to have struck the Ali Al-Salem Air Base in Kuwait as retaliation — CENTCOM states all Iranian attacks on US forces were intercepted. Trump dismisses reports of a talks suspension as "false and erroneous," insisting "conversations are ongoing continuously." Iranian state media report preparations to fully close Hormuz; the IRGC threatens shipping in both Hormuz and Bab el-Mandeb. Brent crude spikes ~7% intraday and trades above $95/bbl.

CENTCOM launches "measured and deliberate" strikes on Iranian radar installations and a drone ground control station at Goruk and Qeshm Island in response to Iran shooting down a US MQ-1 Predator operating over international waters. US fighter aircraft destroy the ground control station, neutralize air defenses, and down two one-way attack drones that posed threats to merchant shipping. Iran denies the MQ-1 was over international waters.
source: Al Jazeera →US-Iran tentative 60-day MOU agreed; Hormuz reopening and nuclear talks framework
US and Iranian negotiators reach a preliminary memorandum of understanding to extend the ceasefire by 60 days and open nuclear negotiations, though the text still requires Trump's final approval. Key terms: Hormuz shipping declared "unrestricted" with no tolls and Iran given 30 days to remove mines; US naval blockade lifted proportionally as commercial shipping resumes; sanctions waived to allow Iranian oil sales; Iran commits not to develop nuclear weapons and agrees to first-round talks on its 440 kg of 60%-enriched uranium; Lebanon war also to end under the terms. Iran's Tasnim news agency says the text is "not yet finalised." Trump simultaneously rejects any sanctions relief linked to Iran's highly enriched uranium stockpile, calling that "not happening, no."
source: Al Jazeera →Iran war spending strains military budgets; training cuts, maintenance delays
CNN reported that Operation Epic Fury costs are forcing cuts to routine military readiness. III Armored Corps (70,000 troops, Texas) faced a nearly $292M training budget cut in late April. Navy Admiral Daryl Caudle told HASC lawmakers the 2026 Navy budget "did not account for [Operation] Epic Fury," forcing limits on training exercises, flight hours, and new recruit training. Defense budget expert Todd Harrison warned of "hidden costs" from accelerated equipment wear requiring future supplemental funding. No supplemental had been submitted to Congress as of this date; Rep. McCollum had demanded a detailed cost breakdown by June 11 for the defense bill markup.
US "self-defence" strikes on Iran; no confirmed casualties
US CENTCOM conducts self-defence strikes on Iranian missile-launch sites and boats at Goruk and Qeshm Island in response to maritime threats in the Strait of Hormuz. Iran's foreign ministry alleges repeated US naval harassment of Iranian commercial vessels over 48 hours; the IRGC warns of "certain" reciprocal response. No casualty figures confirmed by either side. (CNN May 25 / Al Jazeera May 25)
CENTCOM self-defense strikes on Bandar Abbas and Goruk; Iran claims MQ-9 shootdown; Qatar talks ongoing
CENTCOM launches "self-defense strikes" targeting two IRGC mine-laying boats in the Strait of Hormuz and a surface-to-air missile site near Bandar Abbas that had fired on US aircraft. Iran's IRGC separately claims to have shot down a US MQ-9 Reaper over the Persian Gulf — CENTCOM has not confirmed the loss. Trump simultaneously declares the blockade will remain "in full force" until an agreement is reached. Iranian negotiators travel to Doha for Qatar-mediated talks with the US focused on a ceasefire extension and Hormuz reopening, with officials expressing hope for a final deal "within days." Iran rejects US demands that it surrender Hormuz toll-collection rights; Secretary Rubio says the strait must be "open, unimpeded, without tolls."
source: Stars and Stripes →Trump: Iran deal "largely negotiated," will be announced soon; Qatar formally re-enters mediation
President Trump announces from the Oval Office that a peace deal with Iran is "largely negotiated" and "will be announced shortly," after phone calls with the leaders of Saudi Arabia, UAE, Qatar, Pakistan, Turkey, Egypt, Jordan, Bahrain, and Israeli PM Netanyahu. Iran's Fars news agency dismisses Trump's announcement as "incomplete and inconsistent with reality," stating the Strait remains under Iranian management per the latest exchanged text. Secretary Rubio says there are "good signs" but key gaps remain on enriched uranium and Hormuz tolls. Qatar formally re-enters mediation with a negotiating team arriving in Tehran. CENTCOM announces passing the milestone of 100 commercial vessels redirected from the blockade.
source: Al Jazeera →Khamenei orders enriched uranium stockpile remain inside Iran; nuclear talks reach deadlock
Supreme Leader Mojtaba Khamenei issues a directive that Iran's ~440 kg stockpile of 60%-enriched uranium must not leave Iranian territory, according to Reuters citing two senior Iranian officials. The order directly blocks a core US-Israeli demand — Trump had insisted the material be transferred out and destroyed; Israel had made uranium export a precondition for declaring the war over. Iranian FM Araghchi tells Pakistani mediators the parties have reached a "deadlock" on this specific issue and that discussions will be deferred to a later negotiation stage. Iran proposes as an alternative that the uranium be diluted under IAEA supervision inside Iran. Oil futures rise on the news. Pakistan's highest-ranking defense official travels to Tehran to restart stalled negotiations; Pakistani mediation is subsequently postponed.

The US Senate votes 50-47 to advance a war powers resolution directing Trump to end hostilities with Iran — the measure passes its procedural vote after Sen. Bill Cassidy (R-LA) flips following his primary defeat. Republicans Rand Paul, Susan Collins, Lisa Murkowski, and Cassidy join nearly all Democrats. The full resolution still requires a final vote, House passage, and faces near-certain presidential veto. Separately, Trump reveals he postponed a planned US military strike on Iran at the request of Qatar's Emir and other regional leaders who urged continued diplomatic track. Iran's First Vice President declares Tehran will no longer permit "enemy" military equipment transiting the Strait.

Drone strikes Barakah nuclear power plant perimeter in UAE; IAEA condemns attack
A drone launched from western Iraqi territory strikes an electrical generator on the outer perimeter of the UAE's Barakah Nuclear Energy Plant in Abu Dhabi's Al Dhafra region, sparking a fire. UAE air defenses intercept two drones but a third hits the generator. No injuries reported; radiation levels normal; all four reactor units continue operating. No group claims responsibility — the UAE's Defence Ministry calls it a "treacherous terrorist attack" and launches an investigation. Saudi Arabia intercepts three additional drones from Iraqi airspace on the same day. IAEA Director-General Rafael Grossi expresses "grave concern" and warns that military activity targeting nuclear facilities is "absolutely unacceptable." The attack triggers sharp criticism from Qatar and Saudi Arabia and a UN Security Council emergency session (condemned May 26). Iran does not claim the attack.
source: Al Jazeera →Trump-Xi summit concludes: China pledges no military equipment to Iran; CENTCOM: Iran defense industrial base 85% degraded
The Beijing summit concludes with a White House readout stating Trump and Xi "agree Iran can never have a nuclear weapon" and that the Strait must be free of tolls and military obstruction. Xi pledges China will not provide military equipment to Iran and expresses interest in purchasing more US oil to reduce dependence on Hormuz. Treasury Secretary Bessent tells CNBC that China will work "behind the scenes" on Iran, calling it "very much in their interest" to reopen the strait. Separately, CENTCOM Admiral Brad Cooper testifies to the Senate Armed Services Committee that Iran's defense industrial base has suffered degradation exceeding 85%, with more than 100 commercial vessels redirected from the blockade. Israel and Lebanon extend their April 16 ceasefire by 45 days following Washington talks.
source: CNBC →CRS: 42 US aircraft lost or damaged in Operation Epic Fury
The Congressional Research Service published IN12692, "U.S. Aircraft Combat Losses in Operation Epic Fury: Considerations for Congress," tallying 42 aircraft lost or damaged: 24 MQ-9 Reapers, 1 MQ-4C Triton, 4 F-15E Strike Eagles, 7 KC-135 Stratotankers, 1 F-35A, 1 A-10, 1 E-3 Sentry, 2 MC-130Js, and 1 HH-60W. The CRS noted the count "may remain subject to revision" due to classification and ongoing activity. Six aircrew were killed (KC-135 crash Mar 12). The report reinforced why $24B of the $29B total cost is attributed to equipment repair and replacement.
Senate war powers resolution fails 50-49; Trump-Xi Beijing summit opens
The Senate's seventh War Powers Act vote to halt the Iran war fails 50-49 — the closest margin yet. Republican Sen. Lisa Murkowski votes for the measure for the first time, joining Collins and Rand Paul; Democrat John Fetterman again crosses the aisle to defeat it. Murkowski cites the expired 60-day WPR clock: "I haven't received clarity from the administration on where we stand." Separately, President Trump meets Chinese President Xi Jinping in Beijing; both sides agree the Strait of Hormuz "must remain open" to support the free flow of energy, and Xi states China opposes any effort to charge a toll for its use. Xi signals China will work behind the scenes to facilitate Hormuz reopening but demands no concessions on Taiwan in exchange, per analysts. Trump claims Xi assured him China would not supply military equipment to Iran.
source: Al Jazeera →Pentagon comptroller: war cost now $29B
Pentagon comptroller Jules Hurst testified before House and Senate appropriations subcommittees that the Iran war has cost $29B — up $4B from the $25B figure given April 29 — attributing the increase to "updated repair and replacement of equipment" and "general operational costs." The $29B figure excludes base damage costs. Defense Secretary Hegseth declined to specify when a supplemental would be submitted; Rep. Calvert urged one "sooner rather than later." Harvard economist Linda Bilmes projected a $1 trillion total cost including long-term costs; Rep. Ro Khanna cited a $631B estimated total economic impact.
US imposes new sanctions on Iranian nuclear and missile procurement networks
The US Treasury imposes new sanctions targeting Iranian entities and individuals involved in nuclear research with possible military applications and ballistic missile/UAV procurement networks. Entities and individuals in China, Iran, Belarus, and the UAE are designated for enabling Iran's military to secure weapons and raw materials for missile and drone programs. No new direct US-Iran military strikes reported.
source: The Hill →Trump: ceasefire on "massive life support"
Trump publicly called Iran's peace proposal response "stupid" and "a piece of garbage," saying he "didn't even finish reading it." Iran demanded an end to the regional war (including Lebanon), lifting of the US blockade and sanctions, release of frozen assets, and compensation for war damage. Trump rejected the proposal as "totally unacceptable." Lebanon-Israel intensive talks scheduled for May 14–15 in Washington. No new official war-cost figures released this week; Pentagon supplemental request remains unsubmitted to Congress.
Hezbollah drone kills IDF reservist; Trump calls ceasefire "on life support"
A Hezbollah explosive drone attack near the Lebanon border kills an IDF reservist — the first confirmed Israeli soldier killed in the period since the April 16 Lebanon ceasefire. Separately, Trump says the US–Iran ceasefire is on "massive life support" after calling Tehran's latest proposal "garbage." Trump aides signal he is more seriously considering resumption of major combat operations. Ceasefire negotiations are deadlocked over sequencing: Iran demands Hormuz and sanctions be resolved before nuclear talks; the US demands Iran halt enrichment and surrender 440 kg of highly enriched uranium first.

Trump: ceasefire "on massive life support"; 4th round Oman talks conclude
Trump declares the ceasefire is "on massive life support" and calls Iran's response "the weakest right now after reading that piece of garbage they sent us," adding "I didn't even finish reading it." The fourth round of US-Iran talks takes place in Muscat, Oman — Foreign Minister Araghchi and US envoy Steve Witkoff lead three-hour negotiations brokered by Omani FM Badr al-Busaidi. Iran proposes a joint nuclear-enrichment project with regional Arab states and US investment as an alternative to dismantling its program; Witkoff denies this is under discussion. Both sides call talks "difficult but constructive" and agree to continue. Iran's FM spokesman Baghaei defends demands as "reasonable" and "legitimate." Talks precede Trump's planned Middle East visit.

Iran delivers counter-proposal; drones strike MV Laya off Qatar; UAE and Kuwait intercept UAVs
Iran sends its formal response to the US 14-point plan via Pakistan. Tehran's counter-proposal demands: end to war on all fronts including Lebanon, compensation for war damage, recognition of Iranian sovereignty over the Strait of Hormuz, lifting of the US naval blockade, guarantees against future strikes, full sanctions removal, and end to the Iranian oil sales ban. Trump calls the response "TOTALLY UNACCEPTABLE." Same day, an Iranian drone sets fire to MV Laya (Liberian-flagged bulk carrier) in Qatari waters 23 nm northeast of Doha — crew extinguished the blaze, no casualties. UAE intercepts two Iranian drones; Kuwait intercepts two more. LNG carrier Al Kharaitiyat transits Hormuz via Iranian-permitted northern route, suggesting Iran is selectively granting passage.
source: Maritime Executive →US presents counter 14-point proposal; Iran reviewing; ceasefire "day 70"
Washington delivers its own 14-point document to Tehran via Pakistan: Iran must halt uranium enrichment for 12 years, hand over ~440 kg of 60%-enriched uranium stock; in return, the US would lift sanctions gradually, release frozen assets, and withdraw the naval blockade as compliance milestones are met. Iran's parliament speaker Ghalibaf calls the plan "more of an American wish-list than reality." Iran states it is "reviewing" the document. Trump posts on Truth Social threatening "escalated military action" if Iran does not quickly agree, calling Iranian leadership "lunatics." Ceasefire enters Day 70 with no formal peace agreement.
