AN/SPG-55 was a tracking and illumination radar for Terrier, Standard SM-1 and Standard SM-2 surface-to-air missile systems. It was used for target tracking and missile guidance on numerous ships of the US and a number of allied navies. The AN/SPG-55 was part of the Mk 76 missile fire control system.
