The Indicator from Planet Money

How Iran is wasting American resources

March 19, 2026

Key Takeaways Copied to clipboard!

  • Iran is employing a cost-effective strategy by using drones costing thousands of dollars to force the U.S. to expend multi-million-dollar missiles, thereby depleting U.S. munitions stores. 
  • The U.S. military has historically favored 'exquisite weapons' (high-end, precise munitions) which take years to produce, creating a vulnerability when faced with high-volume, low-cost attacks like those from Iran. 
  • The U.S. is beginning to counter this threat by deploying anti-drone systems and developing its own low-cost drones, like the Lucas drone modeled after the Iranian Shahad 136, while experts advise shifting focus toward quantity over extreme quality in munitions production.

Asymmetric Drone Warfare Economics

  • Key Takeaway: Iran is leveraging inexpensive drones (costing thousands) against U.S. multi-million-dollar missiles, exposing a significant economic imbalance in the conflict.
  • Summary: The conflict highlights a strategy where Iran uses waves of cheap drones to force the U.S. to use ’exquisite weapons’ like Tomahawks and Patriots, depleting U.S. stores. Iran’s Shahad 136 drones are described as small, propeller-driven aircraft using GPS for impact. This tactic aims to exhaust the U.S. supply of high-end munitions.
High Cost of Exquisite Weapons

(00:03:31)
  • Key Takeaway: U.S. guided missiles, such as the Tomahawk and Patriot, cost millions per unit and require slow, manual production processes, contrasting sharply with low-cost drone manufacturing.
  • Summary: Exquisite weapons are defined as top-of-the-range systems that take years to build up in inventory, sometimes involving manual assembly like drilling screws in white lab coats. Presidents favor these weapons because they are precise and limit collateral damage, though errors in targeting can still lead to civilian casualties, as noted in a strike involving a Tomahawk missile.
Munitions Depletion and Response

(00:05:07)
  • Key Takeaway: The high expenditure rate in the conflict rapidly depleted U.S. missile inventory, forcing the Pentagon to reposition defense systems from other regions.
  • Summary: The U.S. drained an estimated 10% of its Tomahawk inventory in the first three days of the war, leading the Pentagon to move missile defense systems from South Korea and the Indo-Pacific to the Middle East. In response, the Pentagon is deploying anti-drone cannons and launching the ‘drone dominance initiative’ to acquire 200,000 drones by 2027.
Shifting Military Strategy Advice

(00:06:42)
  • Key Takeaway: Military experts advise the U.S. to focus on quantity and producibility for lower-cost munitions, acknowledging the U.S. is less mature in using Shahed-type drones than Iran.
  • Summary: The U.S. is currently less mature than Iran in the operational use of smaller, high-volume drones. The recommended strategy involves enabling Congress to fund low-cost munitions over multiple years, allowing companies to invest in faster, larger-scale production capacity, viewing this as necessary insurance for future conflicts.
