Which area does the U.S. 4th Fleet operate in and where is it located?

• A. Caribbean, Central and South America, and surrounding waters; Mayport, Florida
• B. Atlantic Ocean; Norfolk, Virginia
• C. Mediterranean Sea; Gaeta
• D. Arctic Ocean; Anchorage

Answer: (A)

The U.S. 4th Fleet operates in the Caribbean, Central and South American regions and the surrounding waters, and its home is Naval Station Mayport in Florida. This setup is focused on security cooperation, counter-narcotics efforts, and rapid response within that Latin American and Caribbean theater, aligning the fleet’s mission with the geography it covers.

Why the other options don’t fit: the Mediterranean area is the domain of the 6th Fleet, based near Naples, Italy; the broad Atlantic region is associated with the 2nd Fleet, based in Norfolk, Virginia; and the Arctic/ Anchorage option doesn’t correspond to a current U.S. Navy fleet’s recognized area of responsibility.
