U.S. Military Operation in Iran Costs Up to $500 Million Daily, Research Shows

The ongoing U.S. military campaign against Iran, designated Operation Epic Fury, has cost the United States between $22.3 billion and $31 billion over its first five weeks, according to research from the American Enterprise Institute (AEI) ^[1]. The operation, launched by President Donald J. Trump on February 28, 2026, has involved retaliatory strikes across multiple Middle Eastern countries, including Iran, Iraq, Kuwait, Saudi Arabia, Jordan, and Qatar ^[2].

Additional analysis by the Center for Strategic and International Studies (CSIS) estimates the daily cost of the conflict at approximately $500 million ^[1]. According to a CSIS cost estimate update, the first six days of fighting alone resulted in approximately $1.4 billion in losses ^[3]. The Iran War Cost Tracker, an independent online monitor, displayed a live estimate exceeding $43 billion as of early April ^[4].

Scope and Scale of Financial Toll

Research from the American Enterprise Institute places the total expenditure for the five-week period at up to $31 billion ^[1]. This figure encompasses costs for damaged and destroyed military equipment, personnel losses, and ongoing operational expenses. A separate CSIS analysis, citing Pentagon briefings to Congress, estimated the cost for the first six days at $11.3 billion ^[5].

The daily operational cost, estimated at around $500 million by CSIS, reflects the intensity of the campaign ^[6]. This expenditure rate indicates the conflict is consuming financial resources at a pace comparable to prior major U.S. military engagements. According to AEI senior fellow Elaine McCusker, replacing equipment damaged in Iranian retaliatory strikes has required an additional $2.1 billion to $3.6 billion ^[1].

Key Equipment Losses and Repair Challenges

Significant U.S. military assets have been damaged or destroyed during the conflict, according to research summaries. These include a Boeing E-3 Sentry airborne warning and control system, multiple radar systems in Qatar and Jordan, and naval base facilities in Bahrain ^[2]. The USS Gerald R. Ford aircraft carrier also requires repairs following issues with its waste systems during an extended deployment ^[2].

The cost to replace this damaged equipment is estimated between $2.1 billion and $3.6 billion, according to AEI ^[1]. Repair timelines vary significantly. ‘Damaged equipment can sometimes be repaired in days, while some destroyed systems will take years to replace on a one-to-one basis,’ said Elaine McCusker, a senior fellow at AEI ^[2]. This highlights the long-term logistical and financial strain beyond immediate operational costs.

Specific Asset Damage and Personnel Casualties

Beyond high-value systems like the E-3 Sentry, the operation has seen the loss of more than a dozen MQ-9 Reaper drones, multiple F-15E fighter jets, and a KC-135 tanker, according to reports ^[2]. The scale of material loss contributes directly to the soaring cost estimates provided by analysts at AEI and CSIS.

The human cost of the operation has also been documented. Research indicates that 13 U.S. soldiers have been killed and 373 others injured since the conflict began ^[2]. These casualty figures are part of the broader assessment of the operation’s toll, which includes both financial and human dimensions.

Strategic Implications and Operational Strain

Analysts note that the operation has strained U.S. military resources ^[2]. The loss of critical radar systems, in particular, has raised concerns about vulnerabilities in regional missile defense networks, according to CSIS analysts ^[2]. The financial and material costs are impacting broader U.S. strategic readiness, the institutes reported.

The high daily expenditure occurs alongside a White House proposal for a record $1.5 trillion defense budget for fiscal year 2027, a request influenced by the costs of the Iran conflict and other global commitments ^[7]. The Congressional Budget Office has previously noted that operations and maintenance can constitute a major portion of defense spending, a reality underscored by the current conflict’s burn rate ^[8]. The ongoing costs have prompted scrutiny from some lawmakers and analysts regarding the campaign’s duration and strategic objectives.

Conclusion

Research from major Washington think tanks quantifies the substantial and ongoing financial burden of Operation Epic Fury. With daily costs estimated at $500 million and total expenditures over five weeks reaching up to $31 billion, the campaign represents a significant drain on U.S. military and fiscal resources. The costs encompass extensive equipment losses, complex repair challenges, and personnel casualties.

As the conflict continues, these financial metrics provide a tangible measure of its impact, beyond the geopolitical and human toll. The data underscores the scale of the commitment as the administration navigates the war’s strategic and economic consequences.
