The California State Military Museum is located at 1119 Second Street in the Old Sacramento State Historical Park. It is only a few minutes walk from the State Capital, The California State Railroad Museum and several other fine museums, parks, and tourist attractions. The museum, opened by Governor Pete Wilson in 1991, is the official military museum and historical research center of the State of California. This was reinforced on 11 September 2002 when Governor Gray Davis signed legislation making the museum a permanent museum under the California State Military Department and providing permanent funding for the museum. Finally on 13 July 2004, Governor Arnold Schwarzenegger signed legislation to amend the Government Code to make the museum the state's official military museum.
The Aerospace Museum of California Foundation is a 501 (c) (3) non-profit organization that was formerly known as the McClellan Aviation Museum. The Museum has been in existence since 1982. The name was changed in 2005 to reflect the new vision focused on education and to reflect the full heritage of aviation and aerospace in the Sacramento region.
