The U.S. war in Iran has cost $25 billion so far, Reuters reported, citing a senior Pentagon official who provided the first official estimate of the American military’s price tag for the conflict.

Jules Hurst, who is performing the duties of the comptroller, told lawmakers on the House Armed Services Committee that most of that money was for munitions.

Hurst did not detail what that cost estimate included and whether it took into account the projected costs of rebuilding and repairing ⁠base infrastructure in the Middle East damaged in the conflict.

Rep. Adam Smith, the top Democrat on the House Armed Services Committee, responded to Hurst: “I’m glad you answered that question. Because we’ve been asking for a hell of a long time, and no one’s given us the number.”

The $25 billion cost is equal to the entire budget of NASA for this year, according to Reuters.
