<!-- [[File:Flag of Johnston Atoll (local).svg|thumb|The unofficial flag of Johnston Atoll, designed by Cheryl Velk, was chosen in a contest among the island's residents organized by the Air Force in 2000. The double bird holding four stars represents the Air Force and the Fish and Wildlife Service, while the four stars denote the atoll's islands; the white is for coral, and the blue represents the surrounding ocean.<ref>{{Cite journal|last=Klimeš|first=Roman|date=March 2011|title=Lesser-Known Symbols of Minor U.S. Possessions|url=https://nava.org/wp-content/uploads/2014/10/NAVANews_2011_no209.pdf|journal=NAVA News|volume=209|access-date=March 14, 2021|archive-date=June 6, 2021|archive-url=https://web.archive.org/web/20210606112859/https://nava.org/wp-content/uploads/2014/10/NAVANews_2011_no209.pdf|url-status=dead}}</ref>]] File was deleted from Wikimedia Commons - November 29, 2023   -->
In 2003, structures and facilities, including those used in JACADS, were removed, and the runway was marked closed. The last flight out for official personnel was June 15, 2004. After this date, the base was completely deserted, with the only structures left standing being the Joint Operations Center (JOC) building at the east end of the runway, chemical bunkers in the weapon storage area, and at least one [[Quonset hut]].<ref>{{cite web|title=Mark in the Pacific – The Last Day|url=http://home.earthlink.net/~markinthepacific/id5.html|access-date=April 7, 2012|archive-url=https://web.archive.org/web/20120816133756/http://home.earthlink.net/~markinthepacific/id5.html|archive-date=August 16, 2012|url-status=dead}}</ref>

Built in 1964, the JOC is a four-floor concrete and steel administration building for the island that has no windows and was built to withstand a [[Saffir–Simpson scale|category IV]] [[tropical cyclone]] as well as atmospheric nuclear tests. The building remains standing but was gutted entirely in 2004 during an [[asbestos abatement]] project. All doors of the JOC except one have been welded shut. The ground floor has a side building attached that serves as a facility for decontamination. It contains three long snaking corridors and 55 shower heads one could walk through during decontamination.<ref name="Hurricane"/>

Rows of bunkers in the Red Hat Storage Area remain intact; however, an agreement was established between the U.S. Army and EPA Region IX on August 21, 2003, that the Munitions Demilitarization Building (MDB) at JACADS would be demolished and the bunkers in the RHSA used for disposal of construction rubble and debris. After placement of the debris inside the bunkers, they were secured, and the entries were blocked with a concrete block barrier (a.k.a. King Tut Block) to prevent access to the bunker interior.<ref name="Baseline"/>
