The AN/FPN-16 is an operating in X-Band precision GCA (Ground Controlled Approach) radar equipment. It may be used as an independent precision radar system to monitor aircraft final approaches, but is primarily designed to function as an integral part of a complete GCA system which incorporates (in addition to the AN/FPN-16) radio communications and search radar facilities. The purpose of the equipment is to present aircraft altitude, range, and flight course information for use by the Control Center in directing the approach and landing of aircraft during periods of reduced visibility.
Radar Set AN/FPN-16 was put into service in 1951 and is similar to AN/CPN-4 and AN/MPN-11, differs in that AN/FPN-16 does not include the search portion of equipment and is not trailer mounted.
