Got to agree with you, it's still a problem now. ASW skills are perishable, and if not constantly exercised are lost. I'm here in Groton still in the community and my friends on the boats worry about it too!

I was a BQQ-5 tech. They now run the Busy-2. It is a much better system but if you have no engine, reactor or reduction gear noise. Your dead. Four to 10 knot cavitation is just not heard well. Let's hope they are looking for new types of sensing. I think we have reached the limits of passive sonar. The fly boys can still go active but the sound absorbing tiles are showing up more and more. Underwater wake detection is limited by the target speed underwater. These new non-nuke boats can stay down longer. We need to work hard on this problem.
