I am building a accurate HMNB Portsmouth, home to the Royal Navy for hundreds of years. Using google maps with the 3d mode enabled, im trying to make this place. i think its coming along pretty well :) All ships within this map are 100% my own builds.


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);^[2] the shipbuilding, repair and maintenance element of the base was privatised in the late-1990s/early-2000s.

The base is home to one of the oldest dry docks in the world, as well as being the headquarters for two-thirds of the Royal Navy's surface fleet. The base is also home to a number of commercial shore activities (including a ship repair facility operated by BAE Systems Maritime); naval logistics, accommodation and messing; and personnel support functions (e.g. medical and dental; education; pastoral and welfare) provided by Defence Equipment and Support.

The base is the oldest in the Royal Navy and it has been an important part of the Senior Service's history and the defence of the British Isles for centuries. At one time it was the largest industrial site in the world.^[3] Around the year 2000, the designation HMS Nelson (which until then had been specific to Portsmouth's Naval Barracks in Queen Street) was extended to cover the entire base.

The Naval Base Commander (NBC) since June 2018 is Commodore Jim Higham. The Captain of the Base (COB), since September 2018, is Captain David George Royal Navy. The harbour is under the control of the Queen's Harbour Master (QHM), working to the Captain of the Base, is currently Commander Steve Hopper, who is the regulatory authority of the Dockyard Port of Portsmouth, an area of approximately 50 square miles (130 km²) that encompasses Portsmouth Harbour and the Eastern Solent. QHM Harbour Control is based in the Semaphore Tower building. Shipping movements are handled by a team of admiralty pilots headed by the Chief Admiralty Pilot, Nick Randall.

Portsmouth naval base is home to two-thirds of the Royal Navy's surface ships, and employs up to 17,200 people. In addition, Portsmouth has built sections for, and will be home port to, the two new Royal Navy aircraft carriers, HMS Queen Elizabeth and HMS Prince of Wales. They required the harbour to be dredged to allow safe entry and exit.The project was intended to secure the base's future for the next forty years and would revitalise shipbuilding in the city; but, due to budget cuts in 2013 shipbuilding in Portsmouth was closed in favour of BAE keeping its yards in Glasgow open. It has been speculated this was to help retain Scotland in the union during the 2014 Scottish independence referendum and it has been suggested by the BAE chairman that shipbuilding could return to the city if Scotland voted for independence.

In 1985 a partnership between the Ministry of Defence and Portsmouth City Council created the Portsmouth Naval Base Property Trust to manage part of the historic south-west corner of the Naval Base, under a 99-year lease, as a heritage area: Portsmouth Historic Dockyard. It allows members of the public to visit important maritime attractions such as Mary Rose, HMS Victory and HMS Warrior.
