GEORGES BANK RADAR STATION
US NAVY'S FABRICATION, INSTALLATION, LAUNCHING AND POSITIONING OF TEXAS TOWERS IN THE NORTH ATLANTIC
US Navy photographic report MN-8213
Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

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 Air 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.[2] Funding for design and construction of the towers was approved in January 1954.
Design
Each tower consisted of a triangular platform, 200 feet on each side, standing on three caisson legs. The structures were constructed on land, towed to site, and jacked up to clear the sea surface by 67 feet. Radar and other equipment was then installed on location.
The platform itself contained two floors housing the living areas; two of the legs held fuel oil for diesel generators, while the third held the intake for the desalination unit. The platform roof served as a helicopter landing area. A rotary gantry was suspended from the platform to allow servicing of its underside.
Each platform was equipped with one AN/FPS-3 (later upgraded to AN/FPS-20) search radar and two AN/FPS-6 height finder radars, each housed in a separate spherical neoprene radome 55 feet in diameter. Originally the towers were to be linked to shore by submarine cable, but this was eventually rejected as too costly; the AN/FRC-56 tropospheric scatter microwave link was installed instead, with an array of three parabolic antennas attached to one edge of the platform...
Texas Tower 2... became fully operational in 1958, as did Tower 3; Tower 4 followed in April 1959. The original plan to integrate these radars into the SAGE system had to be modified when the direct cable connection was eliminated; instead, they were used to provide manual inputs.
All the towers were noisy and prone to vibration from the equipment. The relative flexibility of the supports also caused them to shake and sway in response to wind and waves. The frequent and sustained sounding of the platform's foghorns was also an annoyance to the crew.
Tower 4 was plagued with structural problems from the start. It stood in much deeper water than the other two (185 feet, compared to 80 feet for Tower 2)... three sets of cross braces were added between the legs, attached with pin joints... Crewmen were frequently seasick from the swaying, and Tower 4 was nicknamed "Old Shaky".
On September 12, 1960, Hurricane Donna passed over Tower 4, causing severe structural damage, including the loss of the flying bridge hanging beneath the platform, and one of the communications dishes... it was decided to reduce staffing to a skeleton crew and prepare to dismantle the station... At the approach of another storm in January 1961, evacuation of the station was impeded by the inability of the commander to make contact with any of his three immediate superiors; nonetheless the New Bedford set out for the platform. As the storm built, USS Wasp, which was in the vicinity, was also dispatched with the intent of evacuating the station via helicopter, shore aircraft being unable to take off. Both ships reached the vicinity but could do no more than watch the station disappear from their radar. No survivors were recovered, though divers were sent down on the chance that some might have been trapped in the wreckage. Twenty-eight airmen and civilian contractors perished...
