The war in Iran has revealed a daunting structural flaw in U.S. defense procurement: the cost of defending against Iranian drones far outweighs the cost of the drones themselves.

A single $50,000 drone is being met with interceptors worth millions, highlighting an economic imbalance that is reshaping the future of military strategy.

According to a research note published Tuesday, Alpine Macro chief innovation strategist, Noah Ramos highlighted that 38 days of combat in Iran have solidified a thesis the firm has held since Russia’s invasion of Ukraine: “the economics of warfare are shifting irreversibly.”

When The Math Doesn’t Work

The core problem Alpine Macro identifies is a cost asymmetry that makes conventional missile defense economically untenable at scale. Iran’s Shahed drones cost roughly $20,000–$50,000 per unit.

The U.S. has been intercepting them with PAC-3 Patriot missiles at roughly $4 million each and Terminal High Altitude Area Defense, or THAAD, interceptors at $12–$15 million per missile.

Even with interception rates above 90%, the economics are destructive. Iran can sustain drone saturation attacks indefinitely at a fraction of the cost the U.S. bears to neutralize them.

“The cost asymmetry defining the Iran conflict is the single most important structural force reshaping defense procurement today,” Ramos said.

The problem is compounded by ...
