PV is on track with my thinking.
throughout many facets of the cold war from the 60s to the late 80s and probably still today, you hear about the American SSN patrolling off some Soviet naval base tasked with picking up a boomer headed out to sea and following him around in case the order ever came to take them out.
yes, im sure that was boring
but if they were to just go active sonar all the time and instantly find that patrolling SSN, then how would he ever sneak in behind the boomer and follow him?
you with me?
we hear about the cat and mouse games that these attack submarines play with one another, following them around or sneaking into their baffles without their knowing... in cold waters its not impossible, ive done it several times. But its nearly impossible because when the mission starts and you get a minute or two in you hear that long lonesome ping. then maybe another and then launch transient and its over, the cat and mouse game is over and you're only 90 seconds into the mission start and now everyone is running around flank speed like call of duty multiplayer style run and gun.
