You can tell it's a "paper napkin" design because it's very literally a linear scale-up of Bismarck all the way to including the now pointless catapult launching area which now has the same square area as an Iwo Jima LPH.
This drawing literally demonstrates near-zero knowledge of nautical engineering. Everything I just said I basically repeated years ago on Spacebattles, where people still wank over this.
Wasn't this ship drawn before?
A former user drew it as an imaginative exercise, yes. With at least a little more practical engineering knowledge thrown in for good measure.
EDIT: My comments apply specifically and only to the "napkin drawing" that was posted before, not to Lord Bladamine's Shipbucket-style attempt.
