The Museum of RAF Firefighting aims to to re-establish and develop a narrative of the story of military firefighting with a particular emphasis on the Royal Air Force.

They cannot tell that story, without telling the story of firefighting in general so in effect, there are two museums in one.
They have 50 vehicles and over 20000 exhibits that allow them to do this.
They are based at RAF Scampton, Lincolnshire.
