We Exist To Win Premierships
It's hard to think of a time when unmanned submarines will make any sense, barring the invention of benevolent and predictable AI that's capable of controlling such a machine.
The main advantage of a conventional sub is how quiet they can be. Meaning they are great at sitting on the sea floor listening for shipping movements. This capability of subs became obsolete with the invention of and improved capabilities satellites.
Further e will never win wars against China, India and other regional behemoths without drones. Russia is one leader in this technology and not surprisingly, as India has their soft under belly and China on their vulnerable east.
Russia is one of the few nations on this planet that can claim they stood by us during WW1 and WW2 and I believe they will be a vital ally again in our time of need. We should be looking at their progress and others, in this area.
No supply lines and no body count. That's the future.
