Youre taking the bait.

It's almost certainly the best excuse they could think up to placate the masses.

Sounds plausible but it would have been identified 10 years ago which is why everyone in the thread thinks it's a dubious claim.

One I would have believed more is that they're worried about being too reliable on the offshore wind which can be easily attacked by a foreign navy or maybe a smaller group.

There is a Belgian company that can use temperarure & other fluctuations in underseas power & cimmunication cables to detect nearby objects etc. I'm sure they are willing to help the US navy if they can convince them the US is a solid NATO partner… ( oh, wait, that might have become difficult…)
