The AN/SPG-49 is an guidance radar developed for use with the RIM-8 Talos missile. It was part of the Mk 77 Talos FCS. This radar was first deployed on the Galveston class cruisers, which were rebuilds of Cleveland class cruisers. The first installation was commissioned in 1958.

The original specification called for the SPG-49 to be mounted on an Mk 37 GFCS pedestal, the SPG-49 being considered to be an universal long-range fire control system for guns as well as missiles. This seems not to have been done operationally.
