So that's communication over 8 nautical miles, or 15 km, presumably line-of-sight. Consumer equipment (5 GHz wimax ac) can do that with a 20x20 cm directional antenna. Have a look at a Ubiquiti NanoStation, for instance. Sticking up a pole with a 20x20 cm fiberglass antenna on it won't give a radar return distinguishable from wave noise even at calm seas.

Those are tests, not operations. They were against friendly targets, specifically consumer wifi/bluetooth devices (based on the wattages). Had the target been actively looking for attacks, the sub would have been located within seconds. You wouldn't do this against an attacker with any ability to respond physically. The only time this would be useful would be against an unsophisticated target, but then why bother with the sub?
An airborne drone could do, does, the same job at 0.01% of the cost and 1/0 less lives on the line. The sub is ridiculous overkill.
Or to p.27 with a flowchart of the "Afloat Computer Network Operations", which uses Fleet Comms to connect to the Annapolis, which connects to a set of antennas?
You wrote "subs won't be at the center of the flowchart", but the sub literally is the closest box to the center of that flowchart.
