I actually believe the radar surveillance excuse (on a technicalities only), if that's what this is going to come down to. The ocean is a big empty place and prime for picking up radar reflections as the background is pretty quiet.
However... how on earth was this not identified like 10 years ago way before these projects were even started? Seems pretty obvious in hindsight.
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.
