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 used on Spruance-class destroyers, Belknap-class cruisers, Leahy-class cruisers, Knox-class frigates, Bronstein-class frigates, Hamilton-class cutters, Raleigh-class amphibious transport docks and many other ship classes. It was replaced by the AN/SPS-49 on newer ships and on ships that received the New Threat Upgrade.
