Finley Air Force Station
785th Radar Squadron

Finley Air Force Station is a closed United States Air Force General Surveillance Radar station. It is located 1.5 miles (2.4 km) west-northwest of Finley, North Dakota. It was closed in 1979 by the Air Force, and turned over to the Federal Aviation Administration (FAA).

Today the site is part of the Joint Surveillance System (JSS), designated by NORAD as Western Air Defense Sector (WADS) Ground Equipment Facility.

History

Finley Air Force Station was part of the last batch of twenty-three radar stations constructed as part of the

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.

The 785th Aircraft Control and Warning Squadron began operations with an

AN/FPS-6
B?) was added during 1959.

At the end of 1959 Finley AFS joined the

Duluth AFS
, Minnesota in 1963. 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.

In 1962 Finley operated an

AN/FPS-90
height-finder radars. The AN/FPS-6 was removed in 1969. Over the years, the equipment at the station was upgraded or modified to improve the efficiency and accuracy of the information gathered by the radars.

In addition to the main facility, Finley operated four unmanned

AN/FPS-18
(P-29C/D) Gap Filler sites:

The Ground to Air Transmitter-Receiver (GATR) facility was located off-station at 47°30′40″N 097°54′05″W / 47.51111°N 97.90139°W / 47.51111; -97.90139, roughly one mile northwest of the main station.

Over the years, the equipment at the station was upgraded or modified to improve the efficiency and accuracy of the information gathered by the radars. The site was transferred to the

ADTAC. The 785th Radar Squadron (SAGE) was inactivated, and radar operations at Finley AFS (Z-29) ceased, on 30 December 1979 when a new Joint Surveillance System
(JSS) was activated at the former GATR site about a mile to the northwest.

The new Finley JSS site (Z-303/J-75) began operations with an

public auction
on 9 July 2000. It is now being demolished.
