>Research subs always dive in calm weather so they can surface in an emergency, there would be zero benefit to having a sub as a support vessel.

...Except that it would make it possible to dive in weather that isn't calm. Do you read your own posts?

>Even less so, if the sub needs to be taken out of the water for repair that couldn't be done without astronomical cost on a submarine. It would cost as much as a new submarine to be able to bring it inside the pressure hull, a modification like that would be a new submarine only more complex and costly than the first.

That's precisely why it would be valuable to have. A home base for a deeper diving submersible which provides a dry 1atm shirtsleeves environment in which to repair, recharge and refill it. The cost would not be "astronomical", a new set of nuclear submarines with a large airlock capable of recieving this baby (pictured) are already on the way.
