Fort Huachuca, AZ
Cochise County, AZ
Fort Huachuca is a United States Army installation under the command of the United States Army Installation Management Command. It is located in Cochise County, in southeast Arizona, about 15 miles north of the border with Mexico. Sierra Vista, which annexed the fort in 1971, is located south and east of the post, and Huachuca City, is to the north and east. Its major tenants are the Army Network Enterprise Technology Command (NETCOM)/9th Army Signal Command and the United States Army Intelligence Center. Libby Army Airfield is located on post and shares the runway with Sierra Vista Municipal Airport; it is on the list of alternate landing locations for the space shuttle, though it has never been used as such.
Fort Huachuca is also the headquarters of Army Military Affiliate Radio System (MARS). Other tenant agencies include the Joint Interoperability Test Command and the Electronic Proving Ground.
The fort is also home to a radar-equipped aerostat, one of a series maintained for the Drug Enforcement Administration by Lockheed Martin. The aerostat is based northeast of Garden Canyon and, when extended, supports the DEA drug interdiction mission by detecting low-flying aircraft attempting to penetrate the United States.
