 In 1945, the two were deactivated and combined forming the Joliet Arsenal.
 The plant was reactivated for the Korean War and renamed Joliet Army Ammunition Plant during the Vietnam War.
 Production of TNT ended in 1976, and the major plant operations closed shortly after in the late 1970s.
 The facility briefly revived an automated load-assemble-pack (LAP) artillery shell operation that was managed by the Honeywell Corporation during the Reagan administration in the 1980s before it was finally closed.
Camp Navajo was originally opened in 1942 in Bellemont, Arizona.

 In 1993 the Department of Defense transferred all ammunition activities to Hawthorne Army Ammunition Plant in Nevada.
 Following the transfer, Camp Navajo was shifted to the Arizona Army National Guard.
