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.
Lisbon Naval Base
The Lisbon Naval Base (Portuguese: "Base Naval de Lisboa"), is the main installation and operational base of the Portuguese Navy. Being located at the former Royal Estate of Alfeite on the south bank of the Tagus river's huge estuary, near the city of Almada, the installation is sometimes referred to as the Alfeite Naval Base.
