The problem is the size and weight. It could not be done. There is no machinery to my knowledge that could accomplish this. Submarines have played a central role in each of your novels. Subs serve as a great platform for the kinds of stories I like to tell.
Subs are also unbelievably sneaky.
Essentially they are great black steel tubes sliding through the water with enough power to obliterate anything they choose to target. It depends upon how the deep the water is. The deeper the water the less likely a successful rescue attempt. I would venture to say, the U.S. would be successful in these circumstances. It would take months.
