Explosion Museum of Naval Firepower

Immerse yourself in the world of weaponry and firearms which is fearsome, powerful and inventive at Explosion Museum of Naval Firepower.

Learn of the damage that was done by the collection of guns, cannons, torpedoes, modern missiles – and even a nuclear bomb – at the former 18th century armament depot of Priddy’s Hard in Gosport, which houses the museum.

Hear the incredible personal stories of those who handled these weapons, including the 662 female munition workers who played a crucial part in the First World War, preparing weapons that helped to win battles. The Explosion Museum of Naval Firepower is a must if you are looking for great family days out in Hampshire.
