COMUSNAVSO:COMFOURTHFLT

COMUSNAVSO/COMFOURTHFLT, or Commander, U.S. Naval Forces Southern Command / U.S. Fourth Fleet, traces its origins to World War II, when the original Fourth Fleet was established in 1943 to counter Axis naval threats in the South Atlantic. After deactivation in 1950, the command’s mission was assumed by other naval entities until its reestablishment in 2008 to address modern security challenges in the Caribbean, Central, and South American regions. Today, COMUSNAVSO/COMFOURTHFLT conducts a range of missions including maritime security, humanitarian assistance, disaster relief, and multinational exercises to strengthen partnerships and promote regional stability. Headquartered at Naval Station Mayport, Florida, the command operates as the naval component of U.S. Southern Command (USSOUTHCOM).
