The original quote was Peter Ustinof and the Mouse that Roared.
I agree with DaveJB, to a point, which I shall come to.
The main point was confirmation. Dave should not be too young to remember that notorious Panorama programme when the station commander, no less, in No 1s, stood in the ops room and gave the mission brief for a ****** operation and told the world about Sosus.
Now we would not have expected a ride in a black Omega but to be dragged by the b*ll*cks had we said that.
John Pack, bless him.
Anyway, a short while later, I read a Soviet magazine article which had a table of different NATO sonobuoys and systems and was illustrated with the ray path plots from the SSQ41 all the way to Sosus. I don't recall if it listed the 1C but it certainly had the 24953 and CZ propagation shown.
They certainly didn't need our confirmation (at our squirrel level).
