The AN/SPW-2 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 SPW-2 was the data link betweeen the missile fire control computer and the missile itself. The SPW-2 operated independently from the tracking radar, allowing the missile to be guided to an intercept point ahead of the target.

Each SPW-2 antenna carried an platform to mount an television camera, which could be used to track the missile at short ranges and to view calibration targets for system alignment.
