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, primarily under the cognizance of the Air Force Logistics Command and later the Air Force Material Command. The United States Coast Guard previously operated Coast Guard Air Station Sacramento at McClellan AFB as a tenant activity, operating and maintaining several HC-130 Hercules 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.
