WASHINGTON (AP) — The Pentagon has spent as much as $1.1 billion on U.S. military operations against Islamic State militants in Iraq and Syria since the mission began in mid-June, including more than $62 million alone in Navy airstrikes and Tomahawk cruise missiles.

U.S. Central Command, in data released Monday, said that the Navy has dropped roughly 185 munitions, including 47 cruise missiles launched from ships in the region. Central Command said Air Force fighter jets have far exceeded those numbers, launching close to 1,000 munitions. The data released Monday broke out the $62 million spent on Navy munitions, but provided no cost estimates for Air Force munitions.
