Over-the-Horizon Backscatter Radar Network, Moscow Radar Site Transmit Sector One Transmitter Building, At the end of Steam Road, Moscow, Somerset County, ME

Significance: The Over-the-Horizon Backscatter radar network was an important physical and scientific product of the Cold War. From theories that had been conceived in the days of early long-distance radio transmissions, and building on over three decades of research into the subject, the network was a tremendous technological and military accomplishment. Although it was only starting operation as the Cold War was ending, the ability of a radar system to warn against low-flying aircraft at distances of up to 1,800 miles away was an amazing step forward in air defense. This structure is one of three transmitter buildings that monitor the signals transmitted by the arrays in each sector. The building in sector one is the largest of three transmitter buildings.
