1918: 1st Fixed U.S. Field Station in Houlton, ME.
11 Nov 1918: The first fixed U.S. field station at Houlton, ME began operation. The Houlton Radio Intelligence Station intercepted German diplomatic communications, primarily from its Nauen Transmitter Station. MI-8 created the Radio Intelligence Service, using selected Signal Corps personnel for the sole purpose of supporting strategic intelligence through radio intercepts during World War I. The United States intelligence services built Houlton as the first unit of its type, and its success helped to lay the foundation for many more United States long-range radio-intercept stations.
