My understanding is that sub is so quiet that it escapes our acoustic detection technology.

Are the MADs adequate?

No. The subs we are talking about selling them are quiet but not above detection and they have serious limitations. The boomers that we have now are so quite they make no noise. I was a FTB in the Navy back in the early 90's and I asked one of the sonar guys about tracking the Ohio class subs we have. He said that they are so quiet that the trick to detecting them is to listen for a void in the water.
