Royal Navy Submarine Museum

Royal Navy Submarine Museum

Discover the extraordinary life of a submariner first-hand at the Royal Navy Submarine Museum.

Explore the depths of Britain’s only surviving Second World War-era ocean-going submarine, HMS Alliance.

See and feel how crew members packed into its small spaces and hear from ex-submariners about how they lived and protected the country in such challenging conditions. Take a peek at Portsmouth Harbour through Alliance’s working telescopes.

Meet a submariner and hear his stories of living on board a submarine. Find out what it was like to share jokes in cramped conditions and how to feed a crew of 65 from a gallery the size of a broom cupboard. The Royal Navy Submarine Museum is a memorable day out for all the family and is a ‘must visit’ when looking for fun days out in Hampshire.
