AN/SPS-40

History

The AN/SPS-40 is a 2D long range air search radar that was used mostly by US Navy ships. It was developed in the 1960's. The radar uses the UHF band, which was at the time the minimum acceptable frequency for a search radar system, as lower frequency's cannot provide enough information. Because of this, the SPS-40 has very long range for it's size and power. Different variants were created but none uses a different antenna. Because of this there are no visible external differences between the variants. Most AN/SPS-40 installations were replaced by AN/SPS-49 radars in the late 1980's and early 1990's as part of the New Threat Update (NTU)

the AN/SPS-13 was an S-band 3-D air search radar based on the AN/SPS-2 and was originally intended for use on destroyers. The weight of the antenna was 11,000 lb. The SPS-13 was unsuccessful, only one was build which was fitted to USS Canberra in the early 1960's.
