Pentagon: ISIS fight has cost $424 million

The war against the Islamic State in Iraq and Syria (ISIS) has cost the United States about $424 million.

That’s the war’s price tag since the U.S. military began its bombing campaign on Aug. 8, Pentagon spokesman Rear Adm. John Kirby told reporters on Tuesday.

Kirby said the mission, recently dubbed Operation Inherent Resolve, costs an average of $7.6 million per day.

{mosads}U.S. forces have so far launched more than 260 airstrikes in Iraq since early August and more than 100 in Syria since September.

Earlier this month, U.S. Central Command said the Pentagon had spent $62 million on Navy airstrikes and Tomahawk cruise missiles.

Some of the cost stems from the military presence in Iraq, where there are more than 1,400 U.S. personnel. No U.S. troops are in Syria. 

The Associated Press recently estimated the war has cost the U.S. more than $1 billion, but that’s since mid-June, when President Obama first authorized U.S. troops to deploy to the region to help Iraqi forces counter the Islamic militant group.

A September report from the nonpartisan Center for Strategic and Budgetary Assessments estimated the war could cost the U.S. between $2.4 million and $22 billion per year depending on a possible increase in U.S. troops.
