History
For the vast majority of its operational lifetime, McClellan was a logistics and maintenance facility for a wide variety of military aircraft, equipment and supplies. Initially known as the Pacific Air Depot and Sacramento Air Depot, in 1939 the base was renamed for Major Hezekiah McClellan, a pioneer in arctic aeronautical tests. Born in 1894, he died on 25 May 1936 when his
Consolidated P-30 which he was flight testing crashed near
Centerville, Ohio.
In 1986, the U.S. Air Force established the McClellan Aviation Museum on what was then McClellan Air Force Base. The museum was later chartered by the

aircraft. CGAS Sacramento continues to operate at McClellan following its closure as an Air Force Base and is the only remaining military aviation unit and installation on the airfield.

In 1993, the base was selected by the Pentagon for closure. At first, McClellan was scratched from a list of bases to be closed, but that decision was faced with allegations that the Clinton administration was playing politics. The base was eventually selected for closure, and there were plans to offset the expected loss of $1.5 billion, and 11,000 jobs, to the California economy. The plan relied on privatization and other investment to offset the economic and employment losses. The base is now McClellan Business Park, a growing business enclave that hosts a diverse mix of companies spread across more than 8 million square feet of space of all types. This former military facility is now home to hundreds of private companies, as well as state, federal and local government agencies. It is also home to AmeriCorps*NCCC Pacific Region
