History

COMUSNAVSO

The Commander, United States Naval Forces Southern Command (COMUSNAVSO) was established in February 2000, with headquarters at Naval Station Roosevelt Roads, Puerto Rico which in early 2004 relocated to Naval Station Mayport, Florida. COMUSNAVSO serves as a main link between the U.S. Navy and the navies of South America, Central America, and the Caribbean, and is at the forefront of U.S. engagement in the Western Hemisphere. The command consolidates functions previously conducted by the Commander, Western Hemisphere Group, formerly in Mayport, Florida and the Commander, South Atlantic Force, U.S. Atlantic Fleet (COMSOLANT), formerly located at Naval Station Roosevelt Roads, Puerto Rico. COMUSNAVSO was built around the core of COMSOLANT, that was established in June of 1958 with headquarters in Trinidad and Tobago and was moved to Roosevelt Roads, Puerto Rico in 1973. COMSOLANT had participated in annual "UNITAS" deployments around South America since 1960, and routinely deployed to Africa for the West African Training Cruise since 1980.

In addition to UNITAS, COMUSNAVSO participates in navy-to-navy exercises, counter drug operations, port visits, humanitarian missions, disaster relief, new horizons, and protocol events. COMUSNAVSO exercises military command and control of all assigned ships and units, and represents the U.S. Southern Command with respect to naval matters in the region.
