The AN/SPS-17 is a long-range air-search radar developed for the United States Navy during the early Cold War, primarily used on the Guardian-class radar picket ship. It was the first major postwar P-band air search radar.
Although this radar set did not see widespread service in the U.S. Navy, it led to the development of several far more prolific radar systems, including the AN/SPS-29, the AN/SPS-37, the AN/SPS-43, and the AN/SPS-40.
In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/SPS-17" designation represents the 17th 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.
