The AN/SPG-51 is an American tracking / illumination fire-control radar for RIM-24 Tartar and RIM-66 Standard missiles. It is used for target tracking and Surface-to-air missile guidance as part of the Mk. 73 gun and missile director system, which is part of the Tartar Guided Missile Fire Control System.[2]
Aircraft tracking is based on monopulse radar utilizing Pulse-Doppler radar signal processing in MK 74 MOD 14 and MK 74 MOD 15. The MK 74 MOD 15 configuration includes continuous-wave radar tracking in addition to pulse-Doppler tracking. It provides illumination for bistatic radar operation associated with missile guidance in all configurations. Older systems rely on conical scanning rather than monopulse.

Variants
- SPG-51: Original Model.
- SPG-51B: Upgraded SPG-51 designed for use with Improved Tartar (IT) missile.[9]
- SPG-51C: Automatic acquisition and tracking, increased reliability, and improved ECCM capabilities, clutter rejection, and multiple target resolution.
- SPG-51D: Klystron replaced with traveling-wave tube to permit the transmission to be chosen from a much wider bandwidth. Increased use of integrated circuitry and digital circuitry.[10]
- SPG-51E: Proposed "universal fire control radar" capable of controlling the RIM-8 Talos as well as Tartar.[11] Not built in quantity.[12]
