US-Israel Military Campaign Against Iran Costs $3.7 Billion in First 100 Hours, CSIS Reports

KUALA LUMPUR — In a development that has sent shockwaves through global financial and defense sectors, a new report from the Center for Strategic and International Studies (CSIS) reveals that the joint US-Israeli military campaign against Iran has incurred a staggering $3.7 billion in costs within its first 100 hours.

As the conflict, dubbed “Operation Epic Fury,” intensifies, the sheer scale of the financial commitment is raising urgent questions about the sustainability of modern, high-intensity warfare in the Middle East.

According to the CSIS analysis, the primary driver of this astronomical figure is the unprecedented rate of precision-guided munition (PGM) expenditure. In the initial phase of the campaign, over 2,000 missiles were deployed against hundreds of strategic Iranian military installations and critical infrastructure.

The most significant portion of the expenditure—approximately $3.1 billion—is dedicated solely to the replacement of depleted missile stocks. This includes:

• Tomahawk Land Attack Missiles (TLAM): Renowned for their long-range precision but carrying a high per-unit cost.
• Advanced Interceptor Systems: Used to neutralize retaliatory strikes, these defensive assets are essential but increasingly expensive to manufacture.
• Joint Direct Attack Munitions (JDAM): High-volume usage in tactical sorties.

The operation has seen the deployment of high-end stealth bombers and carrier-based strike groups. The fuel, maintenance, and operational overhead for these platforms have pushed the non-budgeted spending to $3.5 billion, forcing the Pentagon to look beyond its current fiscal year allocations.

The timing of this financial surge presents a significant challenge for President Donald Trump. While the administration maintains that the strikes are necessary for regional security, the domestic optics of a multi-billion dollar “100-hour bill” are becoming a political flashpoint.

With the U.S. economy facing its own internal pressures, the prospect of a massive supplemental defense budget is meeting resistance in Congress. Analysts predict that the request for additional funding will spark a heated debate over national priorities, especially as the cost of Operation Epic Fury is expected to climb if the conflict enters a prolonged “war of attrition” phase.

Market observers are closely watching the $3.7 billion figure as a bellwether for global oil prices and shipping insurance rates. If the cost of neutralizing threats in the region continues at this pace, the indirect economic impact could far exceed the direct military spending.

The CSIS report serves as a stark reminder that modern air campaigns against sophisticated adversaries like Iran are not “low-cost” endeavors. Unlike previous asymmetric conflicts, Operation Epic Fury involves overcoming advanced air defense networks, necessitating the use of the world’s most expensive military technology.

Conclusion The $3.7 billion spent in less than five days underscores a new era of warfare where technological superiority comes with a massive fiscal burden. For now, the world watches to see if the strategic gains of Operation Epic Fury will justify its historic price tag.
