Long Description:
Las Vegas Air Force Station was initially part of Phase II of the Air Defense Command Mobile Radar program. The Air Force approved this expansion of the Mobile Radar program on October 23, 1952. Radars in this network were designated “SM.” The radar site is located on top of Angel Peak, which is north-northwest of the city of Las Vegas, and east of Mt. Charleston.

The Air Force constructed about 24 main buildings in two LVAFS areas, the Operations and Cantonment Areas. Construction in the Operations Area consisted of four radar towers, four operational buildings, one water pump station, a power building, and five large aboveground fuel tanks. The Cantonment Area contained approximately 5 dormitories a dispensary, a mess hall, an administration building, an automotive shop, a maintenance shop, a storage building, a recreation building, one underground gasoline storage tank, and one large above-ground fuel oil tank. Each building had a smaller day tank for storage of heating oil. Three septic tanks comprised the sewage treatment system.

The station became operational on 1 April 1956 when the 865th Aircraft Control and Warning Squadron was assigned to the new station. The squadron initially used AN/FPS-3 search and AN/MPS-14 height-finder radars at this site, and the station functioned as a Ground-Control Intercept (GCI) and warning station. As a GCI station, the squadron's role was to guide interceptor aircraft toward unidentified intruders picked up on the unit's radar scopes. In 1958 an AN/FPS-20A replaced the AN/FPS-3 search radar.

During 1961 Las Vegas AFS joined the Semi Automatic Ground Environment (SAGE) system, initially feeding data to DC-21 at Luke AFB, Arizona. After joining, the squadron was redesignated as the 865th Radar Squadron (SAGE) on 15 October 1961. The radar squadron provided information 24/7 the SAGE Direction Center where it was analyzed to determine range, direction altitude speed and whether or not aircraft were friendly or hostile. It also became a joint-use facility with the Federal Aviation Administration (FAA). On 31 July 1963, the site was redesignated as NORAD ID Z-163.

An AN/FPS-26A height-finder radar joined the site in 1963. In 1964 an AN/FPS-27 search radar set was installed, and in 1965 the AN/FPS-20A was retired from Air Force service (reportedly, the FAA retained this radar set). In 1968 the AN/MPS-14 height-finder radar was removed.

In addition to the main facility, Las Vegas operated several AN/FPS-14 Gap Filler sites:

Boulder City, NV (SM-163A): 35°59'44?N 114°51'48?W? / ?35.99556°N 114.86333°W? / 35.99556; -114.86333? (SM-163A)
Lathrop Wells, NV (SM-163B): 36°38'43?N 116°20'19?W? / ?36.64528°N 116.33861°W? / 36.64528; -116.33861? (SM-163B)
The 865th Radar Squadron (SAGE) was inactivated 31 December 1969. In 1970 the Air Force relinquished the property to the Department of Interior and transferred accountability for all improvements, with the exception of Buildings 18 and 40, to Clark County. Accountability for Building 18 was transferred to the Atomic Energy Commission (currently DOE) and accountability for Building 40 (Radar Tower FPS-20) was transferred to the Federal Aviation Administration (FAA).

Today, all main buildings in the Operations Area are currently in use. The FAA operates the radar facility in Building 40. DOE maintains Building 18 and leases space to Nellis Air Force Base, and other government and private entities. Clark County leases all other buildings in the Operations Area to other government and private organizations.

The former Cantonment Area is used by Clark County Juvenile Court Services, Spring Mountain Youth Camp (SMYC). Buildings 5, and 44 have been removed, but the foundations are currently used for various functions. The FAA continues to operate the AN/FPS-20A today as part of the Joint Surveillance System (JSS). Both facilities (SMYC and FAA) are restricted access
Squadron number: 865 AC&W Sq.
