We were aware of Operation Bolo a few years later. But I never knew much about it until I recently read Old's book. [AF and the Nav never shared anything!] And now I'm pissed! Although Naval Air was far ahead of the Air Force at the time, I now decades later have learned what I should have known back then, and what Olds belatedly learned - That there was an almost instant translation of enemy fighters' and their controllers' transmissions available to us, but never given!
We were never told, because of OPSEC. Halfway through 1972 I belatedly learned – and probably not should have learned - what Olds had learned 5 years earlier to his anger, when I visited our Red Crown controllers on the USS Truxton. That fruitful visit set up a smaller, Bolo-type deception a few days later that worked because we now knew the bad guys had similar technology and translators. It nearly got me a MiG.
The Spooks saved a lot of Intel that we in the arena could and should have used. Unfortunately and apparently, Vietnam was not worth showing our hand. They saved that particular intel for a future showdown with the Soviet Union.
What you implied (but were too polite to say) is that the DOD/National Intel power structure didn't think fighterpilots' lives were worth risking letting that capability become known to the Russians and Slopes
