Camp Navajo began its tenure as Navajo Ordnance Depot in 1942 with the purpose of storing ammunition to be used in the World War II fight against Japanese forces in the Pacific. At the time, the base was one of the largest in the United States, boasting over 220 miles of roads, 50 administrative and housing buildings and 800 ammunition storage facilities. Following World War II the base called back activity and was renamed to Navajo Army Depot in 1965. In the 1982 it was renamed to Navajo Depot Activity, and in 1993 the name was changed to present day Camp Navajo. In 2002, government approval was given to allow the base to deal directly with the civilian public.



Camp Navajo has had a large number of units stationed on it over the last several decades. While the base does have occasional tenant and temporary units, it maintains only five permanent forces. The 1404th Transportation Company, 362nd Ordinance Company , 819th Sapper Engineer Company, 856th Military Police Company, and the 194th Engineer Detachment.


Camp Navajo has remained largely the same since its establishment in 1942. The same road infrastructure remains, with several additions being made over the past decades. The original 800 ammunition storage facilities remain on the base as well. The base has, however expanded to 170 permanent structures, with a vast majority (140) being used for personnel housing. The remaining buildings are designated for administration, classroom facilities and storage.

At any given time Camp Navajo has the ability to house at least 600 temporarily assigned soldiers, sailors, airmen or Marines. Senior enlisted and commissioned service members have additional private housing options within the base. Those coming to Camp Navajo on permanent station have several options for renting or buying in the local community, as well as on post housing areas.
