The AN/SPS-52 is a United States Navy long-range air search 3D radar that is capable of providing contact bearing, range and altitude. It was used on Baleares and Brooke-class frigates, Charles F. Adams and Hatakaze-class destroyers, Tarawa and Wasp-class amphibious assault ships, Galveston, and Providence-class cruisers and other ships. It was replaced by the AN/SPS-48 on newer ships and ships that received upgrades. The antenna is mechanically rotated for azimuth but electronically scanned for elevation.
In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/SPS-52" designation represents the 52nd 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.
