The Hughes SCANFAR system was the first deployed United States Navy phased array radar system installed on the USS Long Beach (CGN-9) and USS Enterprise (CVN-65). It consisted of two search radars, the AN/SPS-32 and the AN/SPS-33. In 1982, the system was removed from Long Beach, and was replaced by the AN/SPS-48 during a comprehensive overhaul.[1] Despite its failure, the lessons learned were applied to the AN/SPY-1 radar and Aegis combat system. Aboard the Long Beach, the system used AN/SPG-55 radars for missile guidance.

• AN/SPS-32 was a wide rectangular antenna for air surveillance.
• AN/SPS-33 was vertical positioned square set for target tracking. According to Navy documentation, the AN/SPS-33 was frequency scanned in elevation and phase scanned in azimuth.[2]
