[QUOTE="alanB, post: 27581, member: 431"] "The Hunt for Red October" is one of the few Tom Clancy books and movies which I still like (was a fan once but after the second Iraq invasion I realised his rather gung-ho outlook wasn't just fiction but actually shared by the real President and most of nation which soured the books somewhat! Anyway I digress). I've always wandered about the spec's of the sonar system. Given that the operators mostly use headphones, what level of amp/s would they need? Obviously the amps would need to be matched to the microphones (I assume) of the sonar array. Are we talking be digital analogue systems overall? (In the book the hip and happening yankee sonar operator makes fun of the Russian valve based systems .... :D) Of course then there is the whole issue of cables! A nuclear sub is a big sucker, and these arrays are usually towed far enough behind the sub so that the turbulence and cavitation etc from the propellers don't affect the signal. Now there's a thorny issue! [/QUOTE]
