Where the Money Goes
Early-phase daily spending breakdown by category (CSIS first 100 hours analysis). Rates declined significantly after Day 4 as US shifted from Tomahawks to JDAMs.
Munitions & Interceptors
Tomahawk cruise missiles ($3.5M each), JDAMs ($80K each), Patriot PAC-3 and SM-3 interceptors. Largest cost driver — shifted from expensive stand-off weapons to cheaper gravity bombs after Day 4.
Air Operations
Fighter sorties, bomber runs, aerial refueling, tanker and cargo aircraft. Based on CBO unit operating cost rates adjusted for higher wartime tempo.
Naval Operations
Three carrier strike groups deployed (Lincoln, Ford, Bush). Nuclear-powered carriers keep fuel costs low; primary costs are aviation fuel, crew pay, and consumables.
Equipment Losses
4 F-15Es (~$100M each), 24 MQ-9 Reapers ($30M each), 1 MQ-4C Triton, 7 KC-135 Stratotankers, 1 F-35A, 1 A-10, 1 E-3 Sentry, 2 MC-130Js, 1 HH-60W — 42 total aircraft lost or damaged per CRS report IN12692 (May 13, 2026). 4 AN/TPY-2 THAAD radars (~$485M each), 1 E-7A radar aircraft ($700M, struck at Prince Sultan AB Mar 27). CSIS total-attrition estimate: $2.3–2.8B; CBS News / internal US officials put full asset losses at ~$11.9B when bases and specialized equipment included. Pentagon comptroller attributed $24B of the $29B total to equipment repair/replacement.
Intelligence & ISR
ISR platforms including MQ-4C Triton, RQ-4 Global Hawks ($176M each), satellite imagery, and cyber operations. Several drones lost over Persian Gulf.
Personnel & Logistics
Ground operations, combat pay, supply chains, medical support for ~50,000+ deployed personnel. CSIS estimates ~$1.6M/day for ground ops.
What $35.58B Could Have Funded Instead
Each dollar spent on Operation Epic Fury is a dollar not spent elsewhere. Here is what the same total would have bought in civilian programs at current unit costs.
Timeline
Trump admin "stand down for now" — "vessels can move freely"; US-Iran agree to Doha talks Jun 30; CENTCOM-IRGC deconfliction channel "up and running"; IRGC claims 8 sites struck (Ali Al Salem AB Kuwait + Fifth Fleet Port Salman Bahrain); CENTCOM: "no reported US casualties or major impacts"; Lebanese MoH 4,246 killed / 12,190 wounded; no new DoD cost figures
June 29, 2026 — (1) Trump administration "stand down for now": A Trump administration official announced on June 29 that both sides would "stand down for now and vessels can move freely" — The Hill confirmed, CNN live blog confirmed. The announcement came after four consecutive days of US-Iran kinetic exchange (Jun 25–28). No formal MOU amendment was published. (2) Doha talks June 30: US and Iran agreed to meet in Doha, Qatar on June 30 — Bürgenstock technical talks relocated to Doha after the military flareup. CENTCOM-IRGC deconfliction channel in Doha described as "up and running" per Vance/Republic World. (3) IRGC claims 8 military infrastructure sites struck: IRGC stated it struck 8 military infrastructure sites overnight Jun 28–29 (02:00–03:00 local time) — identifying Ali Al Salem Air Base in Kuwait and US Fifth Fleet Port Salman in Bahrain as primary targets. A US official stated CENTCOM assessed "no reported US casualties or major impacts or damage" from IRGC claimed strikes (Tribune India, ANI News, House of Saud, PressTV search snippets). IRGC warned: "our response will be more severe than the last time every time the enemy violates the ceasefire." Iran MFA also threatened "complete halt" to nuclear negotiations in protest at CENTCOM strikes. (4) Lebanese MoH 4,246 / 12,190: Al Jazeera Jun 27 cited Lebanese MoH at 4,246 killed / 12,190 wounded — up from 4,230 / 12,179 (WAFA Jun 25). Increase (+16 killed / +11 wounded) covers Jun 26 Israeli strikes; 1 killed and 2 injured in Nabatieh Jun 27 (first casualty since Israel-Lebanon framework signed Jun 26). No new US KIA or WIA. No new official DoD cumulative cost figures Jun 29; $29B (Hurst, May 12) remains most recent official figure; $95M/day ceasefire-standby rate in COST_PHASES unchanged.
IRGC drone strikes M/T Kiku (~2M bbl crude); CENTCOM 10-target strikes in/near Hormuz (largest since MOU); IRGC claims Kuwait/Bahrain retaliation; ceasefire "at breaking point"; ~5 ships transiting Hormuz; Rubio: Bürgenstock talks resume Jun 29–30; no new DoD cost figures
June 28, 2026 — third consecutive day of US-Iran kinetic exchange since MOU signing. (1) IRGC drone strikes M/T Kiku (~08:00 GMT): Iran's IRGC struck the Panama-flagged tanker M/T Kiku with a one-way attack drone as the vessel transited toward UAE's Fujairah port carrying approximately 2 million barrels of crude oil. No crew casualties; no cargo leak or fire. The attack came despite CENTCOM's Jun 26 strikes on Qeshm/Hormuz and Jun 27 second-night strikes — indicating the IRGC did not stand down. (2) CENTCOM 10-target retaliatory strikes: US CENTCOM struck 10 Iranian military targets "in and near the Strait of Hormuz" — the largest single-day US strike package since the MOU was signed June 15. Targets: military surveillance infrastructure, communications systems, air defense sites, drone storage facilities, and minelayer capabilities. Explosions reported near the village of Tahrui near the port of Sirik. CENTCOM: "After yesterday's U.S. strikes in response to the Iranian attack on M/V Ever Lovely, Iran was given a chance to honor the ceasefire agreement, but elected not to." (3) Trump warning: Trump warned "there may come a point when we are no longer able to be reasonable, and will be forced to militarily complete the job that we very successfully started." (4) IRGC retaliation claimed: Iran's IRGC Navy and aerospace forces claimed joint missile/drone operations targeting US military sites in Kuwait and Bahrain; air-raid sirens sounded in Bahrain; Kuwait came under "hostile" missiles and drones. No new confirmed US KIA or WIA from Jun 28 exchange. (5) Hormuz: Only approximately 5 ships transited Jun 28 (vs. pre-war norm ~93/day); approximately 80 mines remain in or near the strait (~40–50 days clearance work remaining); ceasefire described as "at breaking point." (6) Diplomatic track: Secretary Rubio stated Bürgenstock technical talks expected to resume Jun 29–30; Rubio and Vance accused Iran of "trying to restart its nuclear program." No new Lebanese MoH cumulative figure Jun 27-28; last confirmed 4,230 killed / 12,179 wounded (WAFA Jun 25). No new official DoD/Pentagon/CSIS cumulative cost figures released Jun 28; $29B Pentagon comptroller figure (Hurst, May 12) remains the most recent official cumulative cost; $95M/day ceasefire-standby rate in COST_PHASES unchanged — no new official DoD release.
US CENTCOM strikes Iran (Qeshm/Hormuz) first kinetic strikes since MOU; IRGC claims response on US bases; Israel-Lebanon framework signed at State Dept; Hezbollah rejects deal; Senate war powers 50-48; no new DoD cost figures
Key developments Jun 26-27, 2026: US CENTCOM struck Iranian missile/drone storage facilities and coastal radar sites on Qeshm Island and the Hormuz corridor on June 26 — 4 targets using 6 land-based aircraft; first US kinetic strikes on Iranian territory since the MOU was signed Jun 15. CENTCOM: 'The unwarranted aggression against commercial shipping by Iranian forces clearly violated the ceasefire.' VP Vance: 'Violence will be met with violence.' Trump: 'A foolish violation of our Ceasefire Agreement.' When asked if the US would bomb Iran over uranium enrichment, Trump answered 'Sure, without question.' Iran's IRGC claimed retaliatory strikes on US military installations in Kuwait and Bahrain — no new confirmed US KIA or WIA from either set of strikes. Israel-Lebanon framework agreement signed at State Dept on June 26: Secretary Rubio presided; Daniel Holler (US), Yechiel Leiter (Israel), and Nada Hamadeh (Lebanon) signed; Netanyahu called it a 'major win'; Hezbollah was not present and rejected the deal; IDF withdrawal timeline left open-ended. Senate passed Iran war powers resolution 50-48 on June 23 (largely symbolic/non-binding): Collins, Cassidy, Murkowski, and Paul voted yes alongside nearly all Democrats; Fetterman was the only Democrat to vote no. IAEA DG Grossi at Japan press conference Jun 26: 'There is a bit of a war of statements here. What is undeniable is that we have an MOU.' Jun 27: CENTCOM launched second-night strikes against Iran after MV Ever Lovely attack — Al Jazeera: "US launches second night of strikes against Iran after ship struck by drone." No new Lebanese MoH cumulative figure Jun 26-27; last confirmed 4,230 killed / 12,179 wounded (WAFA Jun 25). No new official DoD/Pentagon/CSIS cumulative cost figures; $29B Pentagon comptroller figure (Hurst, May 12) and $95M/day ceasefire-standby rate unchanged.
Pentagon awards $35.3B Lockheed THAAD contract (quadruples production); IRGC strikes MV Ever Lovely in Hormuz (first since MOU); IMO pauses ship evacuation; Rubio at GCC rejects Iranian Hormuz fees; Brent ~$75; no new DoD cumulative cost figures
Two significant war-related procurement and operational developments on June 24-26, 2026. (1) $35.3B THAAD procurement contract (Jun 24): The Pentagon awarded Lockheed Martin a seven-year undefinitized contract action (UCA) valued at up to $35.3 billion to quadruple Terminal High Altitude Area Defense (THAAD) interceptor production. The Payne Institute estimated US forces fired approximately 198 THAAD interceptors in the first 16 days of Operation Epic Fury — about 40% of total US inventory. Production targets: from ~400 interceptors per year to ~1,600 per year. Facilities: Dallas TX, Sunnyvale CA, Troy AL (Camden AR). The contract is a ceiling on a forward-looking seven-year procurement, NOT a new official cumulative war cost figure. The $29B Pentagon comptroller figure (Hurst, May 12) remains the most recent official cumulative cost; the $95M/day ceasefire-standby rate in COST_PHASES is unchanged pending a new official DoD assessment. (2) IRGC strikes MV Ever Lovely — first attack since MOU (Jun 25): Iran's IRGC struck the Singapore-flagged cargo vessel MV Ever Lovely with a drone approximately 7.5 nautical miles southeast of Dahit, Oman, as the vessel exited the Strait of Hormuz — the first attack on a commercial ship since the June 15-17 MOU signing. No casualties; bridge damaged. The IMO immediately paused its plan to evacuate 500-600 stranded ships from the Persian Gulf. IRGC warned all vessels that only Iranian-designated corridors are permitted through the Strait of Hormuz; it declared the Omani/US-backed evacuation corridor "highly dangerous and prohibited." Brent crude rose ~2.1% to ~$75.26. (3) Rubio at GCC rejects Iranian Hormuz management (Jun 25): Secretary Rubio told GCC leaders in Bahrain there is "zero support" for Iranian tolls: "no country on Earth has the right to charge for the use of international waterways." (4) Jun 26: Bürgenstock technical working groups (nuclear, sanctions, dispute resolution) expected to resume early next week per Pakistan FM. No new US-Iran direct land or facility strikes June 25-26. No new confirmed US KIA or WIA. No new official Pentagon, DoD, CBO, or CSIS cumulative cost figures released June 25-26.
White House submits $87.6B supplemental to Congress ($67B DoD/Iran war); IAEA DG Grossi "going to happen" vs Iran Deputy FM pushback; Israel-Lebanon Washington talks "train wreck"; $35.3B THAAD contract; no new DoD cumulative cost figures
Three significant developments defined June 24-25, 2026. (1) $87.6B supplemental submitted to Congress: The Office of Management and Budget formally submitted an $87.6 billion supplemental spending request to Congress on June 24 — the first formal supplemental submission of the war. The package breaks down as: $67B for the Department of Defense for Operation Epic Fury costs (including $21B for munitions replenishment, $17.3B for operational costs, $2.4B for drones, $1.7B for readiness, and $12.1B for classified programs); $11.1B for US farm aid; $1.4B for Ebola response; $768M for Energy Department nuclear and energy security; $500M for DC construction projects. The $67B DoD ask is a prospective appropriation request, NOT a new official DoD cumulative cost figure — the most recent official cumulative figure remains $29B (Pentagon comptroller Hurst, May 12). The request met immediate Democratic opposition; Trump reportedly had a shouting match with Republican senators over war powers votes in a private lunch on June 24. (2) IAEA DG Grossi vs Iran on inspections: Speaking at Japan's Fukushima plant on June 24, IAEA Director General Rafael Grossi said inspections of Iran's enrichment sites are "going to happen" under the MOU; he described timing as flexible but the inspections as certain. Iran's Deputy Foreign Minister Kazem Gharibabadi directly pushed back: "These issues will be reviewed and decided only within the framework of a final agreement and as a result of practical action by the other side to end all sanctions." This continues the IAEA access dispute: VP Vance said Jun 22 Iran agreed to invite inspectors "this week" (Tasnim denied); Trump Jun 23 Truth Social claimed Iran "fully agreed to infinity" inspections (Iran FM Baghaei denied). (3) Israel-Lebanon Washington talks described as "train wreck": The Lebanon-Israel Washington talks (State Dept/Pentagon, Jun 23-25; Dan Holler + Dan Zimmerman for US; Secretary Rubio) were characterized by Israeli Ambassador to the US Yechiel Leiter as a "train wreck"; sources described the current round as "least productive to date" per Times of Israel reporting. Both sides frustrated by the linkage between Iran's MOU obligations and the Lebanon ceasefire. No new US-Iran direct land or facility strikes June 24-25. No new confirmed US KIA or WIA. Lebanon MoH: 4,175 killed / 12,164 wounded (Al Jazeera Jun 22 — no new Jun 25 figure confirmed). No new official Pentagon, DoD, CBO, or CSIS cumulative cost figures released June 24-25. The $29B Pentagon comptroller figure (Hurst, May 12) remains the latest official cumulative cost; $95M/day ceasefire-standby rate in COST_PHASES unchanged.
Trump claims Iran "fully agreed" nuclear inspections; Iran FM Baghaei "no new commitments"; Hormuz 35-36 ships (busiest since war); Bürgenstock nuclear working group active; no new US-Iran strikes; no new DoD cost figures
Two major contradictory narratives and Hormuz shipping data defined June 23-24, 2026. (1) Trump IAEA claim: On June 23, President Trump posted on Truth Social: "Iran has fully and completely agreed to highest level Nuclear inspections long into the future (Infinity!!!)" and warned "If they did not agree to this, there would be no further negotiations!" The post went viral and was read as a major diplomatic breakthrough. (2) Iran FM denial: Iran's Foreign Ministry spokesperson Esmaeil Baghaei flatly contradicted Trump, stating Iran has made "no new commitments" on nuclear issues beyond the MOU already signed. Baghaei said IAEA cooperation would continue "under current procedures" only and that Iran had no plans to allow inspection of bombed nuclear sites such as Fordow, Natanz, and Isfahan under new terms. The dispute mirrors VP Vance's June 22 claim that Iran agreed to invite IAEA inspectors "this week" — which Tasnim also denied. (3) Hormuz shipping: CBS News live updates reported June 22-23 saw approximately 35-36 vessels transiting per day — described as the "busiest day for transits since the war began." This is still roughly 35% of the pre-war norm of ~100 ships per day; Iran's IRGC maintained its June 20 closure declaration; CENTCOM continued to dispute the closure. (4) No new US-Iran direct land or facility strikes June 23-24. (5) No new confirmed US KIA or WIA announced. (6) Bürgenstock technical working groups (nuclear, sanctions, dispute resolution) continued their work. (7) Lebanon-Israel Washington talks (State Dept/Pentagon, Jun 23-25) ongoing. (8) No new official Pentagon, DoD, CBO, or CSIS cumulative cost figures released June 23-24. The $29B Pentagon comptroller figure (Hurst, May 12) remains the latest official cumulative cost; $95M/day ceasefire-standby rate in COST_PHASES unchanged.
Vance IAEA claim (Tasnim denies); Hormuz 12 ships; Lebanon de-confliction excludes Israel; Netanyahu "full freedom of action"; Lebanon-Israel Washington talks open; Bürgenstock working groups begin; US Treasury 60-day General License; no new official DoD cost figures
Multiple significant developments June 22-23, 2026: (1) IAEA inspectors: VP Vance said after the June 21 Bürgenstock session that Iran had agreed to invite IAEA inspectors "at the minimum of this week, maybe as soon as today" — US Treasury Secretary Bessent separately confirmed Iran "committed to allow the entry of IAEA inspectors." Iran's IRGC-affiliated Tasnim News Agency denied the claim: "neither mentioned in the memorandum of understanding nor confirmed so far by the Iranian negotiating team." CNN headlined: "Vance and Iranian state media issue conflicting statements over UN nuclear inspector access." (2) Hormuz shipping: Windward reported only 12 ships transited the strait on June 22, down from more than 21 the previous day; five of eight inbound vessels had AIS disabled. Iran's military maintained its June 20 closure declaration; CENTCOM disputed. (3) US Treasury General License: US Treasury issued a 60-day General License (through August 21) authorizing production, delivery, and sale of Iranian oil, petrochemicals, and petroleum products, including associated banking, insurance, and transport services — as required under the MOU. (4) Lebanon de-confliction mechanism controversy: Reports indicated the mechanism would include US/Iran/Lebanon/Qatar/Pakistan but EXCLUDE Israel and France, and limit Israeli military response to "imminent threats" rather than the broader "emerging threats" standard Israel currently applies. Netanyahu issued a statement June 23: "Our forces in southern Lebanon have full freedom of action to thwart any direct or emerging threat...The IDF faces no restrictions in this regard." A US official denied Israel was excluded from the mechanism. (5) Lebanon-Israel Washington talks opened June 23 at the State Department and Pentagon, running June 23-25; Dan Holler and Dan Zimmerman represented the US; Secretary Rubio: Lebanon-Israel negotiations are "the only feasible path to reconstruction, economic recovery, and ending recurrent cycles of violence." (6) Bürgenstock technical working groups (nuclear, sanctions, dispute resolution) began work June 23 — focused on IAEA access to Fordow, Natanz, and Isfahan, Iran's ~440 kg enriched uranium stockpile, and sanctions sequencing. No new US-Iran direct land or facility strikes reported June 22-23. Lebanese MoH toll: 4,175 killed / 12,164 wounded (Al Jazeera Jun 22 — up from 4,057 / 12,121 as of Jun 20). No new official Pentagon, DoD, CBO, or CSIS cumulative cost figures released June 22-23. The $29B Pentagon comptroller figure (Hurst, May 12) remains the latest official cumulative cost; $95M/day ceasefire-standby rate in COST_PHASES unchanged.
Bürgenstock talks proceed: roadmap + Lebanon de-confliction cell agreed; Trump threatens new Iran strikes during session; no new official DoD cost figures
The first round of high-level US-Iran implementation talks under the Islamabad MOU DID take place at Bürgenstock resort on June 21, 2026 — after conflicting early reports on whether the session was canceled. Vance, Witkoff, and Kushner led the US delegation; Ghalibaf, Araghchi, and FM spokesman Baghaei led the Iranian delegation; Pakistan PM Sharif and Qatar PM Sheikh Mohammed bin Abdulrahman served as mediators. The session was disrupted midway when Trump posted Truth Social threats and told Fox News he had warned Iranian officials "We'll hit Iran very hard again, just like we did last week, only harder!!!" and that if Iran closed the Strait "you won't have a country." Ghalibaf declined a photo with the US delegation and Iran's team protested, but remained at the table. The session concluded after approximately 80 minutes; Vance said "We already made progress in the last several hours and I expect we will make additional progress in the hours to come." Pakistan and Qatar issued a joint statement announcing "encouraging progress" and agreement on: (1) a roadmap toward reaching a final deal within 60 days; (2) creation of a "de-confliction cell" between the US, Iran, and Lebanon (facilitated by mediators) to ensure termination of military operations in Lebanon per the MOU's first article; (3) immediate commencement of further technical talks. Iranian FM Araghchi called the outcome "major progress" and said the de-confliction cell is "the first real test" of the agreement. Iran also said it secured waivers for oil/petrochemical exports, lifting of port blockade, release of some frozen assets, and launch of reconstruction plans. No new US-Iran direct land or facility strikes reported June 21–22. Lebanese MoH toll: 4,057 killed / 12,121 wounded (as of June 20, Wikipedia/search aggregation). No new official Pentagon, DoD, CBO, or CSIS cumulative cost figures released June 21–22. The $29B Pentagon comptroller figure (Hurst, May 12) remains the latest official cumulative cost; $80B prospective supplemental ask (Feinberg, Jun 18-19, WSJ); $95M/day ceasefire-standby rate in COST_PHASES unchanged.
Pentagon tells Congress it needs $80B supplemental; Iran re-closes Hormuz citing Lebanon violations; June 19 ceasefire collapses; Vance flies to Switzerland; Bürgenstock talks set for Sunday; Lebanese MoH 3,980 killed; no new official DoD cumulative cost figure
On June 18–19 (WSJ report), Deputy Defense Secretary Stephen Feinberg told lawmakers in phone calls that the Pentagon needs $80 billion to cover Iran war costs and other non-war bills — the first concrete sizing of a supplemental request. The $80B figure covers wartime operations, personnel costs, ship deployments, and munitions replenishment; a full supplemental package including non-defense priorities could follow pending OMB approval. The $29B Pentagon comptroller figure (Hurst, May 12) remains the latest official cumulative war-cost total; the $80B is a prospective supplemental ask, not a new cumulative figure. On June 20, Iran's IRGC declared the Strait of Hormuz closed again, citing Israel's continued strikes in Lebanon as an "explicit breach" of the MOU's first clause — warning all vessels to "absolutely refrain from any movement in the Strait of Hormuz until further notice." CENTCOM disputed the closure, posting on X that "Commercial ship traffic in the Strait of Hormuz increased June 20 as US forces continued operating in the general area to support freedom of navigation" and confirmed 55 commercial vessels had transited. Trump threatened to impose US tolls if no final deal is reached within 60 days. The June 19 Israel-Hezbollah ceasefire collapsed quickly — Hezbollah fired 50+ projectiles at IDF positions overnight June 19–20; IDF struck Nabatieh and surrounding villages on June 20, killing at least 16 people including two children per Lebanese media and first responders (CNBC Jun 20). Lebanese MoH cumulative toll: 3,912 killed / 11,873 wounded (TASS tass.com/world/2148577; ~Jun 18–19); then rose to 3,980 killed / 12,001 wounded after 68 killed in the prior 24 hours (TASS tass.com/world/2149139 / WAFA Jun 19). On the diplomatic track: VP Vance departed Joint Base Andrews on Saturday June 20 for Switzerland; Witkoff and Kushner were already on the ground; Iran's full delegation including Parliament Speaker Ghalibaf, FM Araghchi, and banking and oil officials left Tehran and arrived at Zurich late Saturday night; Pakistan PM Sharif and army chief Field Marshal Asim Munir confirmed participation in Bürgenstock talks set for Sunday June 21; Qatar PM Sheikh Mohammed bin Abdulrahman also arrived in Switzerland Saturday. No new US-Iran direct land or facility strikes reported June 20–21. No new confirmed US KIA or WIA. $95M/day ceasefire-standby rate in COST_PHASES unchanged pending official DoD assessment.
Bürgenstock talks formally canceled; Witkoff en route Switzerland; Israel-Hezbollah renewed ceasefire 4 PM June 19; Iran waives Hormuz fees 60-day MOU period; Araghchi plans Saturday travel; no new DoD cost figures
Switzerland's Federal Department of Foreign Affairs confirmed on June 19 that the planned Bürgenstock US-Iran implementation talks would not proceed, with Iranian officials declining to travel while Israeli strikes continued in Lebanon. Swiss FM spokesman stated the preparatory work at Bürgenstock is continuing but no new date has been provided. Iran demanded a halt to Lebanon fighting before it would send negotiators. On June 19, Israel launched heavy airstrikes on Hezbollah strongholds in Nabatieh Governorate, killing at least 23 people (TASS tass.com/world/2148727); a Hezbollah anti-tank missile struck an IDF Merkava tank near Nabatieh, killing all four crew including the battalion chief (Korea Times Jun 19, Times of Israel Jun 19). An Israel-Hezbollah renewed ceasefire took effect at 4 PM local time June 19, brokered by the US and Qatar. Separately, the Iranian Persian Gulf Strait Authority (PGSA) announced it would waive all planned Hormuz transit fees — for security, safety, environmental, and insurance services — during the 60-day MOU negotiation period (BusinessToday.in Jun 19). US Special Envoy Steve Witkoff departed for Switzerland on June 19; Jared Kushner was already in Switzerland; Iranian FM Araghchi signaled he was planning to travel to Switzerland on Saturday June 20 for the first round of implementation talks (Axios/Haaretz Jun 19). No new US-Iran direct land or facility strikes reported on June 19–20. No new official Pentagon, DoD, CBO, or CSIS cost figures released. The $29B Pentagon comptroller figure (Hurst, May 12) remains the latest official cumulative cost; the $95M/day ceasefire-standby rate in COST_PHASES is unchanged.
Bürgenstock ceremony postponed; Vance not departing; Iran delays delegation over Lebanon strikes; Lebanese MoH toll 3,884; no new DoD cost figures
The formal Bürgenstock signing ceremony scheduled for Friday June 19 did not take place. On the evening of June 18, the White House announced that Vice President Vance was not departing for Switzerland, citing "logistics." Multiple sources (Axios, ABC News, The Hill/AP, Arab News) confirmed the postponement. Underlying cause per reporting: Iran was delaying sending its delegation to Switzerland due to continued Israeli military strikes on Lebanon — Israeli strikes hit the Nabatieh area and surrounding villages on June 18, killing approximately 58 people in the prior 24 hours. Iran's Lebanon-complication tripwire (that the MOU requires hostilities to end "on all fronts including Lebanon") remained operative and unresolved. The White House stated the US delegation is "prepared to depart at the first available opportunity." No new US-Iran direct land or facility strikes reported on June 19. Lebanese MoH cumulative toll rose to 3,884 killed / 11,856 wounded as of June 18 (TASS Jun 18), up from 3,826 / 11,851 (Jun 16 per Middle East Eye). CENTCOM Hormuz mine-clearance operation ongoing: USS Frank E. Peterson (DDG 121) and USS Michael Murphy (DDG 112) transited the strait; CENTCOM stated it will share a "safe pathway" with the maritime industry once established; additional underwater drones expected to join the effort. Most commercial vessels remain at anchor pending insurance market clearance. No new official Pentagon, DoD, CBO, or CSIS cumulative cost figures released on June 19. The $29B Pentagon comptroller figure (Hurst, May 12) remains the latest official cumulative cost; the $95M/day ceasefire-standby rate in COST_PHASES is unchanged.
Trump signs MOU hard copy at Versailles; MOU declared "in force"; Iran Pezeshkian signs; Bürgenstock June 19 ceremony in question; no new DoD cost figures
During a dinner with French President Emmanuel Macron at the Palace of Versailles on June 18, President Trump personally signed a hard copy of the US-Iran Memorandum of Understanding, with the White House declaring the agreement "in force with immediate effect." Iranian President Masoud Pezeshkian also signed the document. Iran's official response: "The text of the Islamabad Memorandum of Understanding was finalized with the signatures of the presidents — now it is time to test the implementation of the agreement." Iran's Parliament Speaker Ghalibaf — who had signed the digital version June 15 — warned: "If the United States does not honor its commitments, there is no way Iran will honor its own commitments." The MOU's immediate-effect clause calls for Iran to reopen the Strait of Hormuz and the US to lift its naval blockade simultaneously. Trump said the full MOU text would be released "pretty soon" but after Friday, adding: "The Strait opens. It's open now, but it opens completely." The planned formal Bürgenstock signing ceremony in Switzerland (June 19) was thrown into uncertainty — one source reported it "paused" after the Versailles signing, while Iranian officials still referenced a Friday ceremony; the June 19 event's status remained unclear as of reporting. First Iranian oil tankers had already begun leaving the Strait on June 17 per ship-tracking monitors, ahead of formal mine-clearance (which Iran committed to completing within 30 days). US Navy Admiral Daryl Caudle told HASC that without a supplemental appropriation, the Navy would begin cutting training, flight hours, and personnel programs by July. No new official Pentagon, DoD, CBO, or CSIS cumulative cost figures were released June 18. The $29B Pentagon comptroller figure (Hurst, May 12) remains the latest official cumulative cost. The $95M/day ceasefire-standby rate in COST_PHASES is unchanged — phase-rate implications of the MOU entering full force await an official DoD assessment.
Bürgenstock formal signing confirmed June 19; Israel Lebanon violations complicate MOU; Iran parliament ratification vote; no new DoD cost figures
The Swiss Foreign Ministry confirmed the formal MOU signing ceremony will take place at Bürgenstock resort (Nidwalden, Switzerland) on Friday June 19 — not Geneva city as initially reported. VP Vance confirmed he plans to attend, with Trump possibly also present. A significant complication emerged: Iran's army reported Israel had violated the Lebanon ceasefire 84 times since the MOU digital signing on June 15, warning the "aggressor should expect a harsh response." Netanyahu publicly stated Israel would not leave south Lebanon, contradicting the MOU's requirement to end hostilities "on all fronts including Lebanon." Trump said he is "not happy" with Israel's Lebanon handling. Iran's FM Araghchi reiterated: "Without the withdrawal of Israeli forces from territories they occupied, the war cannot be considered fully concluded." Iranian parliament held a scheduled ratification vote on the MOU on June 17; outcome not confirmed by authoritative public sources as of reporting. Lebanese MoH cumulative toll: 3,798 killed / 11,781 wounded (Jun 15, TASS/palinfo.com); 3,826 killed / 11,851 wounded (Jun 16, Middle East Eye). At least 14 killed in Israeli strikes on June 16 per IndexBox. No new US-Iran direct military strikes reported June 17. No new official Pentagon, DoD, CBO, or CSIS cost figures released. The $29B Pentagon comptroller figure (Hurst, May 12) remains the latest official cumulative cost.

MOU digitally signed by Trump, Vance, and Ghalibaf; Hormuz open in principle; most ships not yet transiting; no new DoD cost figures
On Sunday June 15, 2026, Trump, Vice President JD Vance, and Iran's Parliament Speaker Mohammad Bagher Ghalibaf digitally signed the US-Iran Memorandum of Understanding — the document that formally extends the ceasefire for 60 days, authorizes the Strait of Hormuz to open toll-free, lifts the US naval blockade, and initiates 60 days of nuclear negotiations. The MOU is described as "about a page and a half" long; the text has not yet been publicly released (Trump said it will be made available after the formal Geneva signing on June 19). Vance told CNBC on June 15: "We fundamentally have all the cards here." Key MOU terms per US officials: Hormuz toll-free; blockade lifted; Iran removes mines in 30 days; Iran commits not to develop a nuclear weapon, agrees to surrender its ~440 kg enriched uranium stockpile, and allows IAEA inspectors back in; a $300B reconstruction fund (financed by Gulf states, not the US Treasury) available to Iran if it meets compliance milestones; details of uranium disposal to be negotiated in the 60-day window. Despite Trump declaring the Strait "open," most ships were not yet transiting as of June 15–16 due to suspended maritime insurance and the need for mine-clearance corridor confirmation — shipping experts expect 3–4 months for traffic to normalize. No new US-Iran military strikes on June 15–16. No new official Pentagon, DoD, CBO, or CSIS cost figures were released. The $29B Pentagon comptroller figure (Hurst, May 12) remains the latest official cumulative cost. The $95M/day ceasefire-standby rate in COST_PHASES unchanged pending a new official DoD assessment after deal implementation begins.
Trump declares deal "now complete"; authorizes Hormuz opening and blockade removal; signing June 19 Switzerland; G7 discusses deal June 15; no new DoD cost figures
Late June 14, Trump declared the Iran deal "is now complete," posting on Truth Social that he authorizes "the toll free opening of the Strait of Hormuz, and, simultaneously herewith, authorize the immediate removal of the United States Naval blockade." Pakistan PM Sharif confirmed the formal signing ceremony is scheduled for Friday June 19 in Switzerland with VP Vance and special envoy Witkoff. Deal terms confirmed: Hormuz opens toll-free immediately; US naval blockade lifted; Iran removes mines within 30 days; $25B in frozen Iranian assets released; Iran commits not to produce a nuclear weapon; 60-day window for nuclear and enriched uranium talks; hostilities end including in Lebanon. On June 15, G7 leaders at the Évian summit discussed the consequences of the agreement, the lasting Hormuz reopening, Lebanon support, and concluding an Iran nuclear accord (Macron); UK, France, Germany, and Italy welcomed the deal; UN Secretary-General Guterres called it "a critical step." No new US-Iran land or facility strikes reported June 14–15. No new official Pentagon, DoD, CBO, or CSIS cost figures released for this period. The $29B Pentagon comptroller figure (Hurst, May 12) remains the latest official cumulative cost. The $95M/day ceasefire-standby rate in COST_PHASES remains in effect — if the MOU is signed and Hormuz reopens, phase-rate implications will require a new official DoD assessment before this config is updated.
Trump says deal to be signed Sunday in Geneva; Iran FM disputes June 14 date; Vance: language still being finalized; no signed MOU; no new cost figures
Trump stated publicly on June 13–14 that the US-Iran deal would be signed "on Sunday" (June 14) in Geneva, with VP Vance as the US signatory and Iran's Parliament Speaker Qalibaf as the Iranian signatory. Trump posted that "immediately after it is signed, the Hormuz Strait is OPEN TO ALL." US Treasury Secretary Scott Bessent said a deal could come "this weekend or Monday." However, Iran's Foreign Ministry stated the MOU "won't be signed on Sunday" but could happen in "coming days," and Iran's state-affiliated Fars news agency called a June 14 Geneva signing "completely baseless." VP Vance told reporters they are "going back and forth on a couple of language points" and said it is "hard to say exactly when, or if, the president's going to sign the MOU." Deal terms confirmed by multiple mediator and US official sources: Hormuz to be unrestricted with no tolls; Iran removes mines within 30 days; US naval blockade lifted as Hormuz reopens; $24B in frozen Iranian assets released; Iran commits not to pursue nuclear weapons; enriched uranium disposal negotiated in 60-day window. No new US-Iran land strikes reported June 14. No new official Pentagon, DoD, CBO, or CSIS cost figures released. The $29B Pentagon comptroller figure (Hurst, May 12) remains the latest official cumulative cost; $95M/day ceasefire-standby rate in COST_PHASES unchanged pending any signed deal and subsequent DoD announcement.
Pakistan PM declares "final, agreed upon text" of MOU reached; Vance says "still TBD"; Geneva signing proposed for June 14
Pakistani Prime Minister Shehbaz Sharif announced on June 12–13 that "a final, agreed upon text of the peace deal has been reached" between the US and Iran, with the agreement being referred to as the "Islamabad MOU" in recognition of Pakistan's mediation role. The Trump administration named VP Vance as the signatory and confirmed Geneva as the venue for a proposed June 14 signing ceremony, with four US Air Force C-17s departing to Europe to prepare logistics. However, Vance publicly described the signing timing as "still TBD," and Iran's Foreign Affairs Ministry spokesperson said Iran is in "final stages of internal deliberations" and could not confirm where or when a signing would occur. Iran's FM Araghchi stated the deal "has never been closer" but urged caution on media speculation "pending its finalisation." The MOU framework calls for: Hormuz to reopen immediately without tolls; a 60-day ceasefire extension (including Lebanon) during which nuclear negotiations would be held; Iran to receive sanctions relief based on compliance; and Iran to commit not to obtain a nuclear weapon. The MOU was not signed as of June 13. No new official Pentagon, DoD, or CSIS cost figures were released; the $29B figure (Pentagon comptroller Hurst, May 12) remains the latest official cumulative cost. Pending any signed deal and subsequent DoD assessment, the $95M/day ceasefire-standby rate in COST_PHASES remains in effect.
Trump cancels strikes, claims "great settlement" reached; IAEA Board resolution passed; no new DoD cost figures
On the evening of June 11, Trump posted on Truth Social that he canceled "scheduled strikes and bombings against Iran this evening," claiming "discussions and final points have been, in both concept and great detail, approved by all parties involved." From the Oval Office, Trump said "We just made a great settlement of the war with Iran, subject to finalization of documents" and anticipated a signing "maybe in Europe" with VP Vance in the coming days. The deal framework envisions Hormuz reopened with no tolls, US naval blockade lifted, Iran commits not to obtain a nuclear weapon, and a 60-day window for talks on Iran's enriched uranium. Iran's FM spokesperson Baghaei stated "Iran has not reached a final decision regarding any agreement." Netanyahu said Israel is "not a party" to the emerging MOU. Separately, the IAEA Board of Governors on June 10 passed a resolution (21 for, 3 against, 10 abstentions) demanding Iran declare its uranium stockpiles and grant inspectors immediate access — a 97-day monitoring blackout was cited. No new official Pentagon, CBO, or CSIS cost figures were released for this period. The $29B Pentagon comptroller figure (May 12) remains the most recent official cumulative cost; no supplemental request has been submitted to Congress. Active strikes were conducted June 9–11, but the phase rate implications await official DoD release.
Iran strikes US bases in Bahrain, Kuwait, Jordan; Hormuz fully closed again
Iran's IRGC launched retaliatory strikes against US forces in Bahrain (Fifth Fleet HQ), Ali Al Salem airbase in Kuwait, and Muwaffaq Salti Air Base in Jordan (housing F-35s) after the US strikes over the downed Apache. The US launched a second round of attacks on "multiple targets in Iran" on June 10, with Hegseth defending the escalation: "If we need to negotiate with bombs, we'll negotiate with bombs." US strikes also hit two water storage reservoirs in Sirik County (Hormozgan Province), supplying drinking water to ~20,000 residents — Iran called it a war crime. Iran declared complete closure of the Strait of Hormuz to all vessels. No new official Pentagon cost figures were released; Rep. McCollum's June 11 deadline for a DoD cost breakdown passed without a Pentagon response.
Iran downs US Apache helicopter over Strait of Hormuz; US retaliates
An Iranian Shahed one-way attack drone shot down a US Army AH-64 Apache helicopter patrolling over the Strait of Hormuz. Both crew members were rescued safely within two hours by an unmanned Navy drone boat. CENTCOM launched "self-defense" retaliatory strikes beginning at 22:00 GMT June 9 through ~01:00 GMT June 10, targeting Iranian radar sites, ground control stations, and air defense sites near Hormuz — including positions on Qeshm Island, Sirik, Jask, and Bandar Abbas. The strikes marked the most intense US-Iran military exchange since the April 8 ceasefire. No new cumulative cost figures were released by DoD for this exchange.
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.
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.
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.
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.
US strikes Iranian ports; tankers disabled
After Iranian fast-attack craft fired on USS Truxtun, USS Mason, and USS Rafael Peralta (no hits), the US launched "self-defense strikes" on Iranian port facilities. F/A-18s disabled two Iranian oil tankers — M/T Sea Star III and M/T Sevda — in the Gulf of Oman. Trump called the strikes "just a love tap." The US blockade had by this point turned away 58 vessels attempting to reach Iranian ports.
Iran War Funding Prohibition bill introduced
Rep. Pat Ryan leads 17 Democratic colleagues — including 14 Democratic veterans and ranking members of the HASC, Foreign Affairs, and Intelligence Committees — in introducing legislation to bar further Iran war spending absent an AUMF or formal declaration of war. Pentagon has yet to submit any supplemental request to Congress; internal estimates of a future ask range from $50B to $200B+.
Trump War Powers letter declares hostilities "terminated"
In a War Powers Act letter to Congress, Trump formally declares hostilities with Iran "terminated" for War Powers purposes — though carrier groups remain forward-deployed and the dual Hormuz blockade continues. Iran sends a fresh peace proposal to Pakistani mediators the same day.
Brent crude tops $126
Crude prices peak at $126/bbl on continued Hormuz disruption and Iranian rejection of new IAEA terms. Pull back to ~$108 May 1 after Iran sends new peace proposal via Pakistan.
Pentagon comptroller: $25B spent
At House Armed Services Committee testimony, Defense Secretary Hegseth and the Pentagon comptroller place direct war costs at $25B through Apr 28. Internal CRS estimates run $40–50B. Penn Wharton Budget Model revises projection to $38–47B (base case $42.5B through end of April).
Baker Hughes warns Hormuz reopening unlikely before H2 2026
Baker Hughes CEO tells CNBC the Strait will not see normal commercial flow before second-half 2026. Roughly 2,000 ships reported stranded. Insurance underwriters quote "no-go" for non-sanctions-cleared transits.
IRGC seizes MV Epaminondas + MSC Francesca
IRGC fast-attack craft seize two cargo vessels in the Gulf of Oman — the first vessel seizures attributed to Iran since the war began. Tehran calls them "in-kind response" to the Touska seizure. Brent crude jumps to ~$118.
Ceasefire expires; Trump extends indefinitely
Two-week ceasefire period ends; Trump extends the cessation of hostilities indefinitely via executive directive. Islamabad negotiations (Apr 11) failed to produce a permanent agreement. Hormuz remains effectively closed — Iran reimposed transit restrictions Apr 18 after briefly announcing reopening. US Navy seized an Iranian tanker (Apr 19). No US-Iran direct strikes since Apr 7.
Pentagon awards $4.7B Patriot contract
Pentagon signs $4.76B deal with Lockheed Martin for PAC-3 MSE interceptors, tripling production from 600 to 2,000/yr by 2030. Stocks were depleted during heavy use in Operation Epic Fury.
Ceasefire announced
Two-week ceasefire (ending Apr 21) brokered by Pakistan PM Sharif and army chief Munir. White House declares major combat objectives met. Ceasefire immediately violated — Israel strikes Lebanon, Iran-aligned forces hit Gulf states within hours. Strait of Hormuz nominally reopened but Iran charges $1M+ toll per ship.
Cost reaches ~$28B
CSIS senior adviser Mark Cancian estimates ~$500M/day ongoing rate. NPR and Irish Times publish cost analyses ($22.3B–$31B range).
IRGC naval commander killed

Frequently Asked Questions
How much does the US-Iran war cost per day?
Costs varied by phase: ~$1.88B/day in the first 6 days (heavy Tomahawk and interceptor use per Pentagon briefing), declining to ~$500M/day as the US shifted to cheaper munitions (CSIS). Since the April 8 ceasefire, standby costs are estimated at ~$95M/day.
What is Operation Epic Fury?
Operation Epic Fury is the US military code name for joint operations with Israel against Iran, which began on February 28, 2026. Initial strikes killed Supreme Leader Khamenei. A fragile ceasefire brokered by Pakistan took effect April 8, 2026.
How much has the US-Iran war cost in total?
As of day 121, the estimated total cost is approximately $35.58B. Penn Wharton Budget Model estimates $27–28B in direct military costs through the ceasefire. CSIS reported $11.3B at Day 6 and $16.5B at Day 12.
Who is paying for the US-Iran war?
US taxpayers fund Operation Epic Fury through the Department of Defense budget. The Pentagon requested over $200B in supplemental funding, later reduced to ~$80–100B. No supplemental has been passed by Congress as of April 2026.
How does the cost compare to other wars?
At its peak rate of ~$1.88B/day (first 6 days), Epic Fury was far costlier per day than the Iraq War (~$410M/day average) or Afghanistan (~$300M/day). Total direct costs through the ceasefire (~$25B Pentagon-confirmed by Apr 28; CRS internal estimates $40–50B) make it one of the most expensive short-duration US military operations in history.
When did the Iran war start?
The US-Iran war — code-named Operation Epic Fury — began on February 28, 2026, when joint US-Israeli strikes hit Iranian military and nuclear installations. Initial strikes killed Supreme Leader Khamenei.
Is the US-Iran war over?
No. A fragile ceasefire brokered by Pakistan took effect on April 8, 2026. On April 19, 2026, the US reimposed restrictions following renewed Iranian missile activity. The status remains contested — standby costs continue to accrue while the conflict is officially paused rather than concluded.
How much does the Iran war cost per US taxpayer?
As of day 121, the US-Iran war has cost approximately $209.29 per US federal taxpayer, based on total spending of $35.58B divided across an estimated 170 million US taxpayers.
How many Americans have died in the Iran war?
Congressional Research Service (CRS R48887) has not yet released a consolidated casualty figure. See our upcoming casualties tracker for verified US service member figures — we only publish numbers that can be cross-referenced against DoD and CRS disclosures.
Has Iran closed the Strait of Hormuz?
Yes — on March 2, 2026, the IRGC announced closure of the Strait of Hormuz to US and Israel-allied shipping. See our Strait of Hormuz tracker for current status, oil price impact, and war-risk insurance rates.
What happens to the cost estimate if the ceasefire fails?
The phased model likely understates a resumption scenario. The ~$500M/day Phase 2 rate assumes US air dominance and a JDAM-dominant munitions mix. Iran is expected to reconstitute air defenses during the ceasefire (as observed in Iraq 1991–2003, Libya, and Serbia rebuilds). A return to combat would require another expensive SEAD/DEAD phase — stand-off cruise missiles, anti-radiation missiles, and interceptor expenditure against reconstituted Iranian launches — before the US could revert to cheaper munitions. First 2–3 weeks of a resumption could run 2–4x the sustained rate. This model does not forecast post-ceasefire scenarios; totals shown are historical through April 8 plus standby positioning since.
Caveat added after a reader methodology question from r/geopolitics, April 21, 2026.
Sources & Methodology
This tracker uses a phased cost model: ~$1.88B/day for Days 1–6 (Pentagon briefing to Congress), ~$500M/day for sustained operations Days 7–39 (CSIS senior adviser Mark Cancian), and ~$95M/day during the ceasefire standby period beginning April 8. All figures are estimates from publicly available sources and should be independently verified before citation.
