The AN/SPS-49 is a United States Navy two-dimensional, long range air search radar built by Raytheon that can provide contact bearing and range. It is a primary air-search radar for numerous ships in the U.S. fleet and in Spain, Poland, Taiwan aboard Oliver Hazard Perry-class frigates, Canada on its Halifax-class frigate (prior to FELEX mid-life upgrade) and New Zealand on its Anzac-class frigates. It formerly served in a complementary role aboard Aegis cruisers with the AN/SPY-1 but the systems are currently being removed during routine upgrade with no replacement.
