The Pentagon told senators behind closed doors that Operation Epic Fury burns $1.9 billion per day — a figure that excludes the missiles being fired and that no one has asked Congress to fund.

Key takeaway

The US is fighting an unfunded war on existing accounts, consuming defence readiness that Congress has not authorised replacing.

Defence Department officials told the Senate Appropriations subcommittee in closed session on Tuesday that Operation EPIC FURY's first six days cost an estimated $11.3 billion — approximately $1.9 billion per day. The figure, disclosed after the briefing by Senator Chris Coons, substantially exceeds the $3.7 billion that CSIS had independently estimated for the first 100 hours. Coons stated the true cost exceeds even the Pentagon's number: $11.3 billion excludes munitions replacement — the Tomahawk cruise missiles, JDAMs, and other precision-guided weapons expended in strikes across Iran, which carry per-unit costs of $1.5 million to $2.4 million.

At the disclosed daily rate, the war's 13-day running total exceeds $24 billion — roughly equivalent to Iceland's annual GDP. Neither The White House nor the Pentagon has requested supplemental funding from Congress. The same Congress rejected the Massie-Khanna War Powers Resolution by seven votes, leaving no legislative mechanism in motion to either fund or constrain the campaign.

The cost disclosure arrived in a closed session — not a public hearing, not a White House budget request. Supplemental war funding historically requires congressional debate: the 2003 Iraq War's first supplemental was $78.5 billion, submitted weeks after the invasion began. The 2011 Libya intervention cost approximately $1.1 billion over seven months. Operation EPIC FURY has spent more in two weeks than the US spent in the entire Libya campaign. Without a supplemental request, costs are being absorbed within existing defence budgets — meaning either other programmes are being deferred or the Pentagon intends to seek retroactive funding once the political dynamics of an active war make denial difficult.

The $1.9 billion per day does not account for economic costs outside the defence budget: the IEA's 400-million-barrel strategic reserve release, the impact on domestic fuel prices as WTI approaches $95, or downstream effects on allied economies. South Korea's KOSPI triggered circuit breakers twice in four sessions . European markets fell 2–3% in a single day . The fiscal cost to the US Treasury is one line in a broader ledger that no single institution is yet consolidating.

Deep Analysis

In plain English

When the US military fights a war, it pays through one of two routes. It can draw from existing defence budget accounts — money set aside for training, maintenance, and equipment. Or it can ask Congress for extra funds, called a supplemental appropriation, which requires a formal vote and public debate. The Trump administration has done neither of the latter. It is spending approximately $1.9 billion per day from existing accounts without requesting congressional approval or additional money. This matters for two reasons. First, Congress is being bypassed on the largest US military operation in over a decade — raising constitutional questions about executive war-making authority. Second, the military is consuming reserves it needs for readiness: training schedules, spare parts, and weapons stockpiles that take years to replace. The true cost is not just the dollars spent — it is the reduced military capacity that will persist long after this conflict ends.

Deep Analysis

Synthesis

The munitions consumption rate creates a cross-theatre readiness problem the $24 billion headline figure conceals. Every long-range precision weapon expended against Iran is unavailable for the Taiwan scenario that US Indo-Pacific strategy is built around. The fiscal cost is theoretically recoverable through future supplementals; readiness depletion on a two-to-five-year munitions replacement timeline is not. The real long-term cost of this operation will be measured in deterrence capacity, not dollars.

Root Causes

Requesting supplemental funding would trigger a mandatory War Powers Resolution debate and force a formal congressional authorisation vote. The administration avoided this by drawing on broad AUMF interpretations and existing appropriations authority. The seven-vote margin on the Massie-Khanna resolution demonstrated the political risk of forcing a formal vote. Fiscal avoidance and legal avoidance are a single strategic decision executed through the appropriations process.

What could happen next?

Meaning
Congress has been effectively bypassed on the largest US military operation in over a decade, with no formal funding authorisation and no war powers vote.

Risk
O&M account depletion within the fiscal year may force an emergency supplemental request, triggering the congressional authorisation debate the administration sought to avoid.

United States×4

Primary parallel: The 1990–91 Gulf War cost the US approximately $61 billion total, but $54 billion was reimbursed by Saudi Arabia, Kuwait, Germany, and Japan through burden-sharing agreements — a net US cost of roughly $7 billion over seven months. The current operation has no burden-sharing framework and has already exceeded that net figure in 13 days.

Counter-parallel: The 2003 Iraq War was initially financed through existing appropriations without formal authorisation before Congress passed 13 emergency supplementals totalling over $800 billion across 20 years. The current administration is replicating the opening fiscal pattern of that approach.

Why it’s relevant now

The Gulf War comparison highlights the absence of any burden-sharing mechanism this time — no coalition partners are offsetting costs at any level. The Iraq War precedent suggests supplemental funding requests are eventually unavoidable, but the political cost of requesting them grows with every week of unauthorised spending.

The $11.3 billion draws primarily from Operations and Maintenance (O&M) accounts — the DoD budget line covering day-to-day readiness, training, and maintenance. Depleting O&M accounts mid-fiscal year forces cancelled exercises, deferred maintenance cycles, and reduced training tempo that are not recoverable within the same year through later supplementals.

The munitions exclusion is the larger fiscal concern. A JASSM-ER costs approximately $1.5 million per unit; a Tomahawk approximately $2 million; a JDAM approximately $35,000. An intensive air campaign expending hundreds of precision weapons daily accumulates replacement costs in the tens of billions across a full replacement cycle — constrained by industrial production rates, not funding alone. Senator Coons' statement that the true cost substantially exceeds $11.3 billion is almost certainly correct by a significant margin.

Consensus view: The Center for Strategic and Budgetary Assessments (CSBA) has documented that modern precision air campaigns consume munitions at rates exceeding current US industrial production capacity, creating readiness gaps that cannot be closed quickly regardless of funding availability.

Counter-view: The Chinese Institute of Contemporary International Relations (CICIR) frames the $1.9 billion daily burn rate as evidence of US strategic over-extension, arguing that simultaneous Indo-Pacific deterrence and a sustained Middle East air campaign is not fiscally sustainable beyond 60–90 days without triggering domestic political crisis.

Key tension: The Stimson Center's security spending programme has noted that munitions replacement lead times of two to five years mean the readiness cost of this campaign outlasts the conflict itself by years — a deferred liability that no supplemental can fully address.

Causes and effects

This Event

$1.9bn a day, no bill to Congress

The Pentagon's disclosed cost of $1.9 billion per day — which excludes munitions replacement — means the war has already cost more than the entire 2011 Libya intervention. At 13 days the running total exceeds $24 billion, with no supplemental funding request submitted and no legislative mechanism to constrain spending after Congress rejected the only war powers challenge by seven votes.

Different Perspectives

China's foreign ministry

Spokesman Lin Jian rejected Treasury Secretary Scott Bessent's 25 August warning that Iranian oil buyers face an "economic D-Day", saying sanctions do not help and that Beijing would safeguard its own rights and interests. China's Iranian crude imports had already halved for unrelated reasons.

Iraq's government and Erbil authorities

Erbil authorities said 10 explosive-laden drones were shot down over the city on 1-2 September with no casualties. Iraq's government condemned the attacks without naming Iran as their source, and neither Washington nor Baghdad confirmed the IRGC's claim to have hit US bases there.

Bahrain Defence Force

The General Command said air defences intercepted several Iranian missiles and drones on 1-2 September and called the use of such weapons against civilians and private property a flagrant violation of international humanitarian law.

Kuwait's Fire Force and foreign ministry

KUNA reported a hostile Iranian drone struck a residential complex in Kuwait City on 2 September; Fire Force spokesman Brigadier General Mohammad Al-Gharib said losses were confined to property. Kuwait's foreign ministry called the attack a clear breach of its sovereignty.

Jordan's Armed Forces

Petra carried a statement that air defences intercepted eight missiles violating Jordanian airspace early on 31 August and 10 of 13 fired on 1 September. The statement named no target and did not address the IRGC's claim to have struck Camp Titin and killed US personnel.

CENTCOM

CENTCOM's 1 September target list named IRGC air defence, radar, maritime and mine-laying sites in Iran but no tanker, after Axios reported anonymous officials describing a Trump-approved "tanker for tanker" drone policy. A CENTCOM spokesman declined to confirm the policy and referred questions to policymakers.
