Post-Corporate, the Tin Triangle's graceful glide-into-the-sunset coincided with the first programme of enhancement (or should that be conception) to Jaguar's self-defence suite; second hand flare dispensers from the States, ECM and chaff pods, and under-wing AIM-9s. And the PWR?; recovered from the outgoing Vulcans!
Drawback was that the PWR's black-boxes were tuned to the length of cabling between Vulcan's cockpit and fin tip, hence 100 feet of co-ax, winding backwards and forwards in Jaguar's spine fairing.
