SCR-296-A - A short-range Gun-Laying Radar Set - A Gun-Laying Radar set built by Western Electric Company. Installed to provide target range and azimuth data to World War II Coast Artillery gun batteries with 6" and larger guns. SCR-296 Gun-Laying RadarDevelopment 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. Immediately after the attack on Pearl Harbor, the Navy expressed concern for the safety of harbors and anchorages. The Coast Artillery did not have a radar to protect the harbors but expected that the SCR-296-A, with lobe switching, could do the job, providing a gun laying radar set for 6" gun batteries and above.
Site Operation  In operation, the SCR-296-A radar could only track one target at a time. Target assignments were made from the harbor HECP/HDCP command posts by telephone, citing the approximate range and azimuth of the target. The SCR-296-A radar operators would then find the target and pass the precise range and azimuth to the plotting room at the gun battery by phone. Two operators were required, one for the range position and one for the azimuth position. The radar operators would continue to track the target and update the plotting room as the range and azimuth changed.  In operation, the range accuracy was about ± 30 yards while azimuth accuracy was about ± 0.20 degree under the best conditions. The set had a dependable range of 20,000 yards on a destroyer size target when properly sited between 150 to 500 feet above sea level. Operating crew consists of 5 men plus a power plant operator and ar radar maintenance man.
* Additional unit included in spares kit.
