Her Majesty's Naval Base, Portsmouth (
HMNB Portsmouth) is one of three operating bases in the United Kingdom for the British
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.
