Cue the I'm an admiral / I'm a lighthouse "give way" joke[1]. As of 2020 we've learned (open source: reuters) that naval vessels may be deadly in hot wars, but don't do so well in full and frank discussions ('shouldering' when grey on grey) with either cargo vessels or arctic-hulled vessels.

Back in fax-spam days, the USN even officially responded to this joke:
“The first time I heard of it was — oh, let’s see, how long — about 10 years ago or so, I think. That story’s so old,” [LANTFLT spokesman, Cmdr. Kevin] Wensing said, “it probably started out back in the galleon days, or back when there was a big lighthouse at Alexandria, Egypt.”
