I suppose fitting it with cameras would have supplemented our Canberra 9s and although not stealthy, flown b*lls out at max altitude, it might have been useful. It has to be remembered, in the 70s we had an air force, why waste resources on trying to make a combat machine out of a business class (quick) bus. Who was going fly it? What other equipment was needed to make it capable: chaff dispensers, flares, missile detector, radar (not the Wx radar it’s fitted with), comms, weapons, paint job, the list would be endless. The sort of war we envisaged back then would have probably overtaken events with Concord and therefore it was/would have been useless.
