Pentagon war costs reach $38 billion
A congressional watchdog puts the Pentagon’s direct Iran-war costs at $38.1 billion, with weapons replacement the largest expense.

What happened
The Congressional Budget Office estimated that the Pentagon spent $38.1 billion on the Iran war through 1 August. It projected $2 billion to $3 billion in additional monthly costs if fighting continues. The agency also warned that replacing depleted missile-defence interceptors could take at least five years.

Questions
- What is the budget office?
- It is Congress’s nonpartisan fiscal analyst, preparing independent spending estimates for lawmakers rather than setting Pentagon policy.
- Why could household prices rise?
- The agency linked a projected inflation increase to higher energy costs spreading through the economy after disruption in the Strait of Hormuz.
- How depleted are interceptor stocks?
- The report put use at as much as two-thirds since the war began, leaving a lengthy replenishment task.
- Why does replacement capacity matter?
- The CBO warned that depleted stocks could limit the Pentagon’s ability to respond to another major conflict before replacements arrive.
