The United States Department of War updated its estimate to Congress, reporting $47.1 billion spent on military operations in the Iran conflict as of October 16, 2026.

A comprehensive overview of ongoing and historical armed conflicts, military engagements and geopolitical tensions shaping the world today.

Escalating conflict between Iran, the US, and regional powers centered on Iran's closure of the Strait of Hormuz, military strikes across the Gulf, NATO's response, and broader diplomatic and economic fallout including sanctions, cyber warfare, and the Israel-Lebanon front. The maritime confrontation between the United States and Iran expanded alongside Iranian missile attacks elsewhere in the region. Iran said it targeted ten vessels near the Strait of Hormuz, while the United States denied that its warships were hit. Jordan said it intercepted 18 of 20 Iranian missiles directed towards a U.S. base, with the remaining two landing in unpopulated areas without reported casualties.
