Yes, as of early 2026, there is a significant and increasing U.S. military presence in Puerto Rico, featuring the reactivation of formerly closed bases to support Caribbean operations. Key installations include the revitalized Roosevelt Roads Naval Station in Ceiba, Fort Buchanan in Guaynabo, and facilities at Rafael Hernández Airport.
Roosevelt Roads Naval Station (Ceiba): Reopened in late 2025/early 2026, this site hosts F-35 fighter jets, helicopters, and, as of Dec 2025, the 158th Air Wing of the Vermont Air National Guard.
Fort Buchanan: Acting as the Army's headquarters in the Caribbean, it is undergoing modernization with a new $30 million operations center, serving as a hub for the 1st Mission Support Command.
Regional Strategy: These bases are actively used for surveillance, logistics, and, in early 2026, supporting military operations related to regional, specifically Venezuelan, stability efforts.
Additional Locations: Operations have
extended to using part of an airport in Ponce for logistics and, by late 2025,
reviving parts of the former Ramey Air Base in Aguadilla.
These moves, driven by the U.S. Southern Command, mark a major return of U.S. military forces to the island.
