KingPin- Presumably this refers to the TWT's in the radar
system, the EW/ECM systems and not the C3 equipment ?
(the Tomcat was certainly not Korean War vintage!) BRBR

The (h)AWG-9 was old technology that was prevelent in early radars seen on the
F-4(AWG-10), never really modified when available technology was present.

Poor reliability, many MH to maintain.
