Royal Navy Submarine Museum

Get up close to HMS Alliance at the Royal Navy Submarine Museum, the only remaining Second World War era submarine. Explore the decks and narrow corridors, look through the original periscope and hear the stories of those who served onboard.

See the museum’s other submarines including Holland I and X24 as well as photographs, documents, ship plans and artefacts from another time.

Discover Silent and Secret, a new exhibition which follows the Royal Navy's at sea nuclear deterrent telling the story of those who served under water for months at a time. See objects that retell hidden conflicts and first-hand accounts from crew onboard.

Take in the history of the site and find out what it was like to face danger underwater. See how a crew of 65 were fed in a galley the size of a broom cupboard.

*COVID Notice: Please note that ALL visitors wishing to go on board HMS Alliance, are required to wear face-covering even if they have a medical exemption. This is due to the restricted airflow onboard the submarine.


After you’ve explored inside the museum, head outside to the memorial garden or to view the harbour area.

If you're looking for the perfect souvenir, head to the museum shop and discover something for every memory made. From pencil toppers to blends of Royal Navy inspired spirits, there's a keepsake for everyone inside.

The Royal Navy Submarine Museum is the perfect place for an adventure with family and friends. Explore HMS Alliance, look through the periscope and hear the stories of those who served on her.
