Royal Navy Submarine Museum

The Royal Navy Submarine Museum is a naval museum in Gosport that focuses on submarine warfare and naval operations. It displays submarines, torpedoes, and equipment across exhibition halls positioned next to Portsmouth Harbour.

The collection started in 1963 as the Submarine Branch Collection and was first housed in HMS Dolphin. It moved to its current location in 1978, becoming a dedicated naval museum that documents submarine history.

The museum displays Jolly Roger flags that submarines raised after successful operations, a custom that reflected how crews marked their achievements. These flags show how submariners developed their own way of celebrating their work during wartime.

Visitors can tour the museum from Wednesday to Sunday, with guided visits of the HMS Alliance submarine included. It is helpful to check opening times before arriving and book guided tours in advance if you want a more detailed experience.

The HMS Alliance, positioned outside the water, is the last remaining ocean-going submarine from the Second World War in Britain. The vessel shows how cramped conditions were aboard these boats and gives visitors a direct sense of life inside a working submarine from that era.
