Any submarine expert here would like to comment how much accurate is his information regarding the sound generated by screw blades and pump jets?
This guy knows nothing exacting about the acoustic performance of either Yasen screws or Borei pump-jets, even if he is an ex-Navy sonar man. Its just general theory without real numbers. You could just as easily apply it to detection of Ohio SSBNs and Seawolf/Virginias. I write it off as typical Yankee bloviating.
no shit is just a general theory...
submarine information of that nature is highly classified.
But as you said he is ex-navy sonar so his ideas are educated.
Tell me have you ever worked on a submarine? no? oh you just read shit on the web and think you know better riiiiiiiiiiiiiiight.
