Hampton Roads
Beginning in 1917, as the United States became involved in World War I under President Woodrow Wilson, formerly rural Sewell's Point became the site of what grew to become the largest Naval Base in the world which was established by the United States Navy and is now known as the Naval Station Norfolk.

The Naval Sea Systems Command (NAVSEA) is the largest of the United States Navy's five "systems commands," or materiel (not to be confused with "material") organizations. NAVSEA consists of four shipyards, ten "warfare centers" (two undersea and eight surface), four major shipbuilding locations and the NAVSEA headquarters, located at the Washington Navy Yard, in Washington D.C.
