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 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

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
258:(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
