The Fourth Fleet operates out of which location?

The Fourth Fleet operates out of Mayport, Florida. This fleet was established to serve primarily in the Caribbean and South American regions, and its headquarters in Mayport enables it to effectively support operations and maintain a strong naval presence in those areas. The location in Florida provides strategic access to key maritime routes and allows for rapid deployment of naval forces as necessary.

The other options, such as Naples, Italy, Yokosuka, Japan, and Norfolk, Virginia, are associated with different fleets or commands within the U.S. Navy. For instance, Naples is primarily associated with the Sixth Fleet, Yokosuka is home to the Seventh Fleet, and Norfolk is home to the U.S. Atlantic Fleet. Each location serves specific strategic purposes aligned with their respective operational theaters.
