Okay, that's big.
That's roughly 200 feet / 60 meters longer than the new Ford Class aircraft carriers... but it probably costs less than 13 billion dollars
They might be a crazy amount of money and might be fast becoming foolishly vulnerable in the modern world of cheap drones, but from an engineering perspective those Nimitz and Ford carriers are incredible machines. 100,000,000 tonnes displacement (a fraction of a big cargo vessel), but they can hit 30 knots.
Neither comes close to the length of the Seawise Giant oil tanker - 458m
I'd love to see any of the three of them up close to get a feel for the scale. There's a thing when describing rockfall where rangers will convert cubic meters to washing machines, which to me means nothing. I always converted rockfalls to aircraft carriers when trying to give the scale of a rockfall. For the largest rockfall in recorded history, it turns out to be the mass equivalent of 16 fully-loaded 1092-foot-long Nimitz-class carriers with 80 aircraft aboard that came tumbling down the walls and across the road in a few seconds in March of 1987.
