AN/APS-116
AN/APS-116 was an operating in X-Band anti-submarine warfare (ASW) search radar. AN/APS-116 was able to detect a submarine periscope in 15.5 nautical miles.
The AN/APS-116 was designed to detect submarine periscopes and antennas in rough seas. The system’s scanner is mounted in a nose radome, and the radar is integrated with the aircraft’s data systems. The APS-116 was also used for navigation and surface search.
The APS-116 used a traveling-wave-tube (TWT) transmitter that drives a cross-field amplifier.
