The AN/SPS-49 is a United States Navy two-dimensional, long range air search radar built by Raytheon that is capable of providing contact bearing and range. The radar is also used by several other countries, such as Australia, Canada, Spain and Taiwan aboard Oliver Hazard Perry class frigates and Canadian Halifax class frigate.

First tested in 1965 aboard USS Gyatt (DD-712) and introduced in 1975, the SPS-49 serves as a primary air-search radar aboard numerous ships world wide. It is also serves in a complementary role aboard Aegis cruisers with the AN/SPY-1. It is an L band radar operating in the 850 - 942 MHz band and has a range of 250 nautical miles. The orange-peel parabolic shape of the antenna creates a narrow 3.3º beam reducing the probability of detection or jamming. It is also capable of rotating at 6 rpm for long range mode or 12 rpm in short range mode.[1]
