And, yes, I know about LPI radars. But the one thing about a long-range radar is that it has to radiate power, and one side can detect the other's transmitter long before they themselves are detected. Now add space elint to the equation, GPS/Inertial guided missiles with ecm terminal homing and blithely boring holes with the radar on will quickly go out of fashion. Even more so, radar ground sites in known/easily pin-pointed stations. Boats, too, for that matter. Might as well have a huge neon sign saying "Hit me". Even in 1960 we had missiles that could switch to ecm home; not much of a step to homing on AI radar with our progress in micro processors. Now bring in satellite elint and direction . . . Fortunately, F22s or F35s in operation won't do that. Both aircraft have intraflight datalinks for cross-linking data among aircraft as well as other links for e.g. downloading the take from RJs and satellite sensors. The IFDLs allow a flight of F22s to share the radar duty cycle across multiple aircraft in whatever strategy most suits the occasion, meaning that any ESM location data on a particular emitter ages fast, especially if it's cruising at M1.5. All the GPS in the world does you no good if you lose location awareness on the target . It's good to see that Lockheed is catching up to Sweden. As an aside, F35s will have not two but seven IR cameras. The FLIR EOTS sensor is augmented by a six-camera Distributed Aperature System of IR sensors that gives the pilot a 4pi steradian field of view, including places where aircraft structure gets in the way. Very cool system BTW. -- Harry Andreas Engineering raconteur |
