The Royal Naval Submarine Museum Gosport allows you to trace the history of submarine development from the age of Alexander the Great to the present day. You can then visit the Holland 1, the Royal Navy's first submarine . You can then take a look at the X24 and LR3. There are torpedoes, guns and missiles to see.
HMS Alliance, the submarine you can go on board, was commissioned in 1947 and allows you to experience life on board a submarine. As your guide (an ex-submariner) takes you through the ship they describe life on board in the 45 minute tour. You can look through the periscopes of HMS Conqueror towards Portsmouth Harbour. There is even an opportunity to be a Captain in the trainer control room. There are galleries telling the history of the submarines and how nuclear physics drives today's submarines.
There is a gift shop and picnic area as well as a restaurant. The museum has a water bus stop which links Portsmouth with the museum. There is a remembrance corner which commemorates those who gave their lives to the submarine service. It includes their medals and tells of how 14 Victoria Crosses were awarded. A visit to the historic ships of Portsmouth is not complete without a visit to the Navy’s under water fleet.
The Royal Navy Submarine Museum was founded as a "Submarine Branch Collection" in 1963. It consisted of three small rooms which were made available in HMS Dolphin, the submarine base. In 1982 a new building was opened as a submariners memorial next to HMS Dolphin. In 2002 the museum won the Pilgrim Trust Conservation Award in recognition of their Holland 1 conservation project.
The John Fieldhouse Building is shaped like a submarine, with the building housing the historic HMS X24 and honours the late Admiral of the Fleet, Lord John Firldhouse the most senior submariner in history. He was in charge of the victorious British Forces in the Falklands War of 1982.
