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.
HMNB Portsmouth
Her Majesty's Naval Base, Portsmouth (HMNB Portsmouth) is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Clyde and HMNB Devonport). Portsmouth Naval Base is part of the city of Portsmouth; it is located on the eastern shore of Portsmouth Harbour, north of the Solent and the Isle of Wight. Until the early 1970s, it was officially known as Portsmouth Royal Dockyard (or HM Dockyard, Portsmouth); the shipbuilding, repair and maintenance element of the base was privatized in the late-1990s/early-2000s.
