History
The AN/SPG-51 is an guidance radar developed for use with the RIM-24 Tartar missile. This radar was first fitted on the Charles F Adams class destroyer. The first installation was commissioned in in 1960. The SPG-51 is used mostly in combination with the Mk 74 Tartar FCS
As originally developed, SPG-51 had an transmitter that was marginal for the improved (17.5 nm range) Tartar missile. Because of that, the later SPG-51A introduced an much more powerful transmitter. SPG-51B, available from 1963 onwards, introduced speed gate filtering which allowed the radar to track targets trough clutter and at higher noise levels. Most SPG-51B's were later updated to SPG-51C standard. The C standard introduced a major upgrade to the electronics, swapping the vacuum tubes for solid state and reducing the complexity of the system to make maintenance easier and reliability higher. SPG-51D was introduced with the Tartar-D (digital Tartar) fire control system, and had an much upgraded transmitter and some modifications to the base antenna.
SPG-51E never reached operational service, and was intended as a universal fire control for both Tartar/Standard and Talos. Talos leaving USN service in the late 1970's made that this development was no longer needed.
The SPG-51 is still in active use by many foreign navies, but has left US Navy service with the decommissioning of the Kidd class destroyers in 1999. In addition to the Kidd, the SPG-51D is still in service on the Durand de la Penne class. The last ship using SPG-51C, the Cassard class, left service in 2021. SPG-51B and earlier did not last beyond 1995.
