In making Explosion, a whole host of specialist subcontractors - audio-visual specialists, model-makers, graphic designers, computer animators worked on different parts of the project. At the same time the museum's small band of conservators, technicians and volunteers have prepared many of the artefacts which are featured in the exhibition.
The work was finished in February 2001 and then, after a period of testing and trials, the museum was fully open to the public in March 2001. The galleries and displays that have been created represent the first phase of development for the museum.
His Royal Highness, The Duke of York formally opened this new museum on Monday 30 April 2001. Prince Andrew had a personal tour of the exciting interactive museum by Director of Explosion, Michael Nutt and unveiled a plaque to commemorate the occasion. The Duke of York was introduced to former workers of the Priddy's Hard Armaments Depot where Explosion is situated and volunteers who carried out some of the conservation work on the exhibits. Bill Adnitt, conservation volunteer said, 'The Duke of York was very knowledgeable about the gun barrels and breeches. We would be pleased to have His Royal Highness on our team any day'.
Explosion was set up as a Charity and run initially by a Board of Trustees. In 2002, the Museum was absorbed by Gosport Borough Council. It remained under council management for seven years.
In October 2009 the Portsmouth Naval Base Property Trust completed the acquisition of Priddy’s Hard and the Museum from Gosport Borough Council.
A new summer waterbus service linking Portsmouth Historic Dockyard to Priddy’s Hard and the Royal Navy Submarine Museum was introduced in 2013, when the Museum joined the National Museum of the Royal Navy group of Museums.
