I was skimming through my latest periodical from the Naval Submarine league and VADM Donnely CSF made this statement. "...The TB-29 is a very capable TA and, when it works, clearly detects contacts that are invisible to other acoustic sensors. But, with a 19% reliability, my CO's have an understanably hard time trusting that it will be there when they need it the most."
This floored me, and I wonder how in the world this TA could have made it to the boats with this kind of poor reliabilty rating. I would have an inbound TLAM heading right to the factory that makes these things.
