Also speaking from utter naivety, this seems like a super good idea. Each submarine gets a little attendant constellation of drones. Control them with Bluetooth. Or usb cables.

Or whiskers! That's how cats and catfish do it. A dozen 300' plastic prongs protruding frontward.

Or, to combine the two : TENTACLES!

Nice idea, but how many ship-lengths does a submarine need to slow down from full to zero speed? Probably more than a few.

The submarine in SeaQuest DSV had mini underwater drones called whiskers that did this job:
