It was the US’s own test of their defences the main thing they were “shooting down” were the US’s own fleet of bombers. it was meant as a full scale test and the RAF was invited kinda for the fun of it. They got through without much effort the first time. Second time, they had to use different tactics, use 3 vulcans to bait the air defences but the 4th got through.
Jamming good enough to defeat the entirety of the US air defences and good enough (with some upgrades) to protect it during the blackbuck raids during the Falklands war.
first time can be chalked up to testing such a big system on such a large scale. ofc stuff will go wrong.
2nd one, didnt they need 3 vulcans to jam? and it was not going against full US air defence. only F-102 and ground radars. and if it was the real deal, im sure even with the jamming they could still locate where it was with enough accuracy for a couple AIR-2’s to wipe out the whole formation.
NORAD. It was a test to see how NORAD’s radar network and defense would fair against a full scale Russian bombing assault. After B-47 flew low and first dropping chaff followed by mid altitude B-52s flying in only 1 of the vulcans was detected and considered a kill.
