Texas Towers
The Texas Towers were a set of three radar facilities off the eastern seaboard of the United States which were used for surveillance by the United States Air Force during the Cold War. Modeled on the offshore oil drilling platforms first employed off the Texas coast, they were in operation from 1958-1963. After the collapse of one of the towers in 1961, the remaining towers were closed due to changes in threat perception and out of a concern for the safety of the crews.
==Planning==
Upon re-formation of the Aerospace Defense Command in 1951 to oversee the nation's developing surveillance radar network, there was concern that shore-based radars along the east coast provided insufficient warning time. A 1952 report from MIT's Lincoln Laboratory looked into the possibility of extending radar coverage by building platforms in the Atlantic using offshore oil drilling technology. They concluded that a set of such platforms, equipped with radars, could extend coverage several hundred miles offshore, giving half an hour additional warning of an attack.〔 Funding for design and construction of the towers was approved in January 1954.〔
