All those Spadeadam runs we did might have been more worthwhile if any of the ECM kit fitted to the tin triangle had been of any use. By the time I flew the beast, all the ECM kit was years out of date and utterly useless...
As I was to learn a year or so later on the F4, all you needed was a couple of locks to wake up the AEO. He would then turn on their missile magnet and we would then have been able to complete the attack without difficulty. Chaff against Pulse Doppler - forget it. IRDs? Only if the Vulcan crew knew you were coming..........which was unlikely unless the Fighter Controllers told them! And even then, no use against SWIFT-enabled Sidewinders.
