HMS Alliance is Britain’s only remaining World War II submarine and stands as a memorial to the 5,300 British submariners who have lost their lives in service.
A tour of Alliance begins in the forward torpedo store, then on through the accommodation space to the control room, where experienced submariner guides demonstrate the navigation systems including diving and surfacing. The tour continues through the galley and on to the heart of the submarine, the engine room, before culminating in the aft torpedo compartment, where the guides explain how submariners would escape in an emergency. Along the way, you can also peer through the working periscopes to view Portsmouth Harbour.
HMS Alliance forms the centrepiece of the Royal Navy Submarine Museum along with Holland I and X24, the museum also contains thousands of photographs, documents, ship plans and artefacts. The Royal Navy Submarine Museum is located in Gosport on the former site of HMS Dolphin; home to the Submarine Service for 100 years. A complimentary waterbus takes visitors across the harbour from Portsmouth Historic Dockyard.
Silent and Secret
A new permanent exhibition exploring the history of the British nuclear at-sea deterrent is now open at the Royal Navy Submarine Museum. The new exhibition opens on the 50th anniversary of HMS Resolution launching. It will reveal the challenging nature of working in these submarines and help promote discussion about why the nuclear deterrent was adopted.
Life under the sea poses challenges that go unseen and unheard. The exhibition will present an insight into life on board the "Silent & Secret" Polaris submarines, using personal accounts and key displays drawn from a number of National Museum of the Royal Navy sites, private lenders and other museums. Visitors will be able to hear stories and see documents and personal possessions of those who served in the Polaris submarine fleet.
