Where is the headquarters for the 2nd Fleet?

The headquarters for the 2nd Fleet is located in Norfolk, Virginia. This fleet is primarily responsible for the operational aspects of naval forces in the North Atlantic and the Arctic, as well as supporting NATO operations. Norfolk, being a major naval hub with significant naval infrastructure, serves as an ideal location for the command of the 2nd Fleet, which allows for efficient coordination of naval operations and resources both in the Atlantic and in allied engagements.

The other locations mentioned, such as San Diego, Yokosuka, and Gaeta, are significant naval installations but are associated with different fleets or commands. San Diego primarily supports the 3rd Fleet, Yokosuka is home to the U.S. 7th Fleet, and Gaeta serves as a strategic location for allied operations in the Mediterranean, notably with the 6th Fleet. Thus, their roles and responsibilities differ, solidifying Norfolk as the correct answer for the 2nd Fleet headquarters.
