The AN/SPS-48 is a US naval electronically scanned array air search 3D radar system manufactured by L3Harris Technologies and deployed in the 1960s as the primary air search sensor for anti-aircraft warships. The deployment of the AN/SPY-1 and the end of the Cold War led to the decommissioning of many such ships, and many of these vessel's AN/SPS-48 sets were reused on aircraft carriers and amphibious ships where it is used to direct targets for air defense systems such as the Sea Sparrow and RIM-116 SAM missiles. Existing sets are being modernized under the ROAR program to AN/SPS-48G standard for better reliability and usability.
In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/SPS-48" designation represents the 48th 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.
