The Military Museums is a reorganization of the former Museum of the Regiments in Calgary, Alberta, announced by Sophie, Countess of Wessex, on June 3, 2006. The new museum comprises the former Museum of the Regiments as well as the relocated Naval Museum of Alberta and an Air Force Wing consisting of artifacts currently being acquired.
The Museum of the Regiments was formally opened by Queen Elizabeth II on 30 June 1990, on what was then CFB Calgary. The museum, partnered with the Calgary Military Museums Society (CMMS), was a joint venture of the four military regiments in Calgary at that time, each with its own gallery.
The Military Museums preserves and documents the history of all three branches of the Canadian Forces and predecessor services (the Royal Canadian Navy, Canadian Army, and Royal Canadian Air Force), with a focus on Alberta history, through an extensive public gallery and archival holding.
