The 84th Combat Sustainment Wing was a wing of the United States Air Force based at Hill Air Force Base, Utah from 2005 to 2014. Its history dates back to the 84th Fighter Wing of 1949. Its mission was to provide system support manager functions for air-to-surface munitions, and multiple Command, Control, Communication and Intelligence (C3I) systems, and supply chain management for space systems, C3I systems, landing gear, power systems and multiple aircraft programs. Perhaps its most notable subordinate organization was the 84th Combat Sustainment Group.
