The United States Air Force (USAF) is the aerial and space warfare branch of the U.S. military, responsible for defending the country through air and space power. It conducts missions involving air support, transportation, reconnaissance, and missile defense. Formed as a separate service in 1947, the USAF plays a critical role in national security and global military operations.

The Air Force also engages in humanitarian missions and disaster response, contributing to both defense and aid efforts worldwide.
