AN/SPS-32

The AN/SPS-32 was a long-range air search and target acquisition radar developed by Hughes for the US Navy. The AN/SPS-32 operated together with the AN/SPS-33, which was the square array used for 3D tracking, into one system known as SCANFAR. It  was installed on only two vessels, the cruiser USS Long Beach and the carrier USS Enterprise, placing a massive power drain on the ship’s electric system. The technology of the AN/SPS-32 was based on vacuum tubes and the system required constant repairs. The SPS-32 was a phased array radar which had a range of 400 nautical miles against large targets, and 200 nautical miles against small, fighter-size targets.
