SCANFAR
The Hughes SCANFAR was the first phased array radar system to be deployed by the US Navy, 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. Aboard the Long Beach, the system used AN/SPG-55 radars for missile guidance.
Despite its failure to enter widespread service, the lessons learned were applied to the follow-on Aegis Combat System and the associated AN/SPY-1 passive electronically scanned array (PESA) radar.
