Moscow Air Force Station
Encyclopedia
Moscow Air Force Station is a closed United States Air Force
radar station in Somerset County
, Maine
. Located 6 miles (9.7 km) northeast of Moscow, Maine
, it went operational in 1990 but was closed in 1997 and placed in "warm storage" with minimal maintenance. It was deactivated and placed in "cold storage" in 2002.
(OTH-B) system. The system was based on a frequency modulation/continuous wave (FM/CW) radar capable of detecting and tracking objects at over-the-horizon ranges. In concept it involved bouncing radar signals off the ionosphere
which allows radar to overcome the curvature of the earth.
A small scale test receiver/transmitter was established in central western Maine at what would become Moscow AFS by the early 1980s. Successful testing resulted in the decision to develop operational OTH-B systems for the east and west coasts and in Alaska.
The east coast OTH-B system was designed and built by GE Aerospace and consisted of an AN/FPS-118 radar with the transmitter located at Moscow AFS and the receiver at the newly constructed Columbia Falls AFS
. The transmitter and receiver stations were manned by personnel of the 776th Radar Squadron
. Data processing took place at the Maine Air National Guard
's Bangor Air National Guard Base
which was close to the geographic halfway point between the TX/RX facilities.
The east coast OTH-B system was tested in the late 1980s and went operational when it was handed over to USAF in 1990. It was the largest of the three OTH-B systems and was so powerful that it could even detect changes in ocean currents.
The fall of the Soviet Union
and end of the Cold War
saw the OTH-B systems rendered obsolete for detecting intruding military aircraft, however, the east coast OTH-B continued operations until 1997 and its data saw use by the United States Border Patrol
for tracking aircraft used by drug smugglers, as well as the National Oceanic and Atmospheric Administration
which made use of the measurements of ocean currents and weather patterns.
The facility was placed in "warm storage" in 1997 and in 2002 it was deactivated and placed in "cold storage" with equipment removed from the site. Reports in 2010 indicate that the Moscow AFS property may be divested and sold for a private wind farm
development. The site was put up for auction in September 2011 through the U.S. General Services Administration
. By October 2011, the arrays had been dismantled and removed from the deactivated station, but microwave towers and various buildings remained. As of November 2011, the land was still up for auction.
