AN/SPG-51
AN/SPG-51 is operating in the C-band gun and missile fire-control radar. It includes an X-band continuous wave target illuminator for the RIM-24 Tartar and RIM-66 Standard missiles.
The dual purpose parabolic reflector has a diameter of 7.7 ft (≙ 2.5 m). The version AN/SPG-51D was fitted with a traveling wave tube Older versions of the target tracking radar used a klystron with a peak power of 30 kW only. The illuminator uses a klystron in all versions.
