Where is Berger on his idea of hunting subs?

 Anyone know where Berger is on his idea of hunting subs? You remember that he talked about using well decks on amphibs for everything except landing craft and amphibious vehicles.

About the same time he talked about how the Ground Combat Element (they really should dump that and call it the Ground Sea Combat Element) can contribute to hunting subs.

Haven't heard much about it.

Is it still a thing they're working on in the background?
