The AN/SPS-43 was a ship-based, 2-dimensional, air-search radar developed and manufactured by the American firm Westinghouse. The AN/SPS-43 was capable of providing bearing and distance information, but no altitude information. With an antenna that looked like a bedspring, it could detect the range and bearing of a target at a long range (300+ miles); the target would then be picked up by a 3-D radar such as the AN/SPS-48, which assuming the target to be hostile would present the target information to a fire-control radar like the AN/SPG-55. Operating at 0,2 GHz, the AN/SPS-43 was introduced in 1961 and, after several years of service with the US Navy, it was replaced by AN/SPS-49.
