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.
Pearl Harbor
Over the years, Pearl Harbor remained a main base for the US Pacific Fleet after World War II along with Naval Base San Diego. In 2010, the Navy and the Air Force merged their two nearby bases; Pearl Harbor joined with Hickam Air Force Base to create Joint Base Pearl Harbor-Hickam.
