The United States keeps an extensive network of military installations in key locations throughout the globe. These facilities facilitate humanitarian or peacekeeping efforts, cooperative operations with allies, and prompt reaction to threats, all of which contribute to America's worldwide military policy.
Each facility serves a distinct geopolitical and operational function and is dispersed throughout North America, Europe, Asia-Pacific, the Middle East, Africa, South America, and Oceania.
Why does the US have Military Bases all over the World?
With the largest network of military installations in the world, the US is able to help its friends, project power, and retain its influence on the world stage. From massive air bases to tiny drone hubs and cooperative facilities, the United States maintains more than 750 military locations throughout more than 80 nations and territories as of 2025. In times of crisis, several US military bases around the world can be quickly deployed for strategic, logistical, and operational reasons.
Together, these installations serve as the foundation for American military supremacy from the Pacific islands to Eastern Europe.
