SCR-296-A

 - A short-range Surface Craft Detection Radar Set - A surface craft detection Radar set built by the Western Electric Company to detect and track seagoing surface craft. Use by the Coast Artillery to provide target range and azimuth data to World War II gun batteries with 6" and larger guns.

SCR-296 Surface Craft Detection Radar
Development of the SCR-296 began in 1941 when the Signal Corps Lab obtained a set from Western Electric Company and enhanced the target tracking ability with a lobe-switching modification. The modified set was designated the SCR-296-A. The Coast Artillery tested it and ordered 20 sets before the attack on Pearl Harbor. After the attack, concern for the safety of harbors and anchorages increased and the Coast Artillery looked to the SCR-296-A radar to provide a surface craft detection radar set for existing 6" and larger gun batteries then protecting all the major U.S. harbors. These harbor defenses were largely outdated and relied upon a complex network of optical spotting stations to provide target data. Advances in ship armament had produced weapons that were capable of offshore bombardment beyond the range of the existing batteries and spotting stations, especially during marginal weather. The SCR-296-A would provide an all-weather target tracking capability near the maximum range of the shore batteries.

The first SCR-296-A was delivered in April 1942, the second in July 1942. The Coast Artillery then had 176 sets on order for delivery before the middle of 1943. This capability coincided with the construction of the new 200 series 6" gun batteries at every significant harbor defense and 100 series 16" gun batteries at selected harbors.

The SCR-296-A Radar equipment was declared obsolete by AG letter on 17 Jan 1946. The tower and radar equipment were to be disposed of while the buildings were to be retained.

Site Operation
When crated, the total weight of the SCR-296-A was 91,763 lbs. The largest component weighed 5,270 lbs. The SCR-296-A package included a tower, a radar operations building, and two power plant buildings. The tower came in heights of 25, 50, 75, and 100 feet and included the wooden antenna housing constructed to look like a water tower. The concrete foundations for the prefab buildings and the tower were engineered by the Corps of Engineers who also erected the structures. The equipment and the equipment installation were usually provided by the Signal Corps. Primary power of 2.3 KW could be supplied by one of two PE-84C generator sets, by post power or by commercial power.
