McClellan Airfield — Sacramento, United States

MCC refers to McClellan Airfield, a former US Air Force base located in Sacramento, California, that has been converted into a civilian airport and industrial business park since its military closure in the 1990s. Originally McClellan Air Force Base was a major logistics and maintenance depot for the Air Force, and its long runways and extensive infrastructure now support cargo operations, aircraft maintenance companies, and general aviation. The site has also become home to various private aerospace and technology businesses that took advantage of the existing hangars and airfield facilities after the base closed. MCC is not used for scheduled passenger service, but it remains an active airfield for cargo carriers, corporate aviation, and testing operations tied to the surrounding McClellan Business Park.
