Iran War Has Cost U.S. Nearly $40 Billion and Fueled Inflation, CBO Finds

The bulk of the spending—$21.7 billion—comes from replacing munitions expenditures, the CBO found, including $13.1 billion for missile defense interceptors and $7.3 billion for land-attack cruise missiles. Other costs include repairing or replacing equipment, increased flying hours for air operations and transportation, and increased fuel costs. However, it does not factor in the cost of damage to U.S. bases and facilities in the Middle East.

The separate report from the Defense Department’s inspector general, released a day before the CBO’s, estimated the cost of repairing “physical damage from Iranian strikes” to U.S. diplomatic facilities in Iraq, Kuwait, Saudi Arabia, and the UAE at approximately $184 million. It also determined that throughout Operation Epic Fury the U.S. military has spent $22.3 billion on munitions and has lost around $3.7 billion in aircraft and equipment, including four destroyed F-15 fighter jets, seven KC-135 tanker aircraft, a dozen damaged or destroyed KC-135 refueling aircraft, and the loss of up to 30 MQ-9 Reaper drones.
