Re: PLAN submarines Thread II
Sonar operations are very skilled individuals and the data they provide is valuable, during the Cold War Royal Navy SSN used the acoustic signatures to determine how many propellers the Russians were using how many blades in each propellers and even the size and propulsion systems
They could even determine if the propellers were damaged or if one was faulty that is the skill of a SSN commander
Submarine warfare is on a another level when it comes to intelligence
Normally, intelligence services would not release noise levels of enemy subs, even if they are high. This would tell the enemy to make improvements on their subs. It was a U.S. spy, John A. Walker, who gave info to the Russians that their subs were emitting too much noise due to propeller cavitation. After the Russians redesign their propellers to reduce cavitation, the noise level of their subs have decreased significantly.
