AN/SPS-40
Sign in to saveAlso known as SPS-40
The AN/SPS-40 is a United States Navy two-dimensional, long range air search radar that is capable of providing contact bearing and range. It was replaced by the AN/SPS-49 on newer ships and on ships that received the New Threat Upgrade. The SPS-40, being a vacuum tube design, was notoriously sensitive to the vibration from shipboard gunfire. A later redesign into a largely solid-state system not only improved its performance (cutting the number of cabinets by more than half) also featured one of the best MTI (Moving Target Indicator) units in the fleet - a rarity in the early 1970s.

In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/SPS-40" designation represents the 40th design of an Army-Navy electronic device for surface ship search radar system. The JETDS system also now is used to name all Department of Defense electronic systems.
