The great fleet sailing on the sea, with the helicopter in the foreground.
KENSUKE (OFF):“She's downright gorgeous! After all, that's the pride of the U.N. forces, the full-scale aircraft carrier...”

UrsusArctos: Lovely overhead shot showing the ships in a parade formation, designed to impress anyone taking photographs or video - in this case, Kensuke. Of course, out in the open ocean they wouldn't be cruising this close to one another, that would bring a serious risk of collision and overly concentrate naval assets that are meant to function dispersed from one another kilometers apart. (Even from an in-universe perspective, it puts them at increased risk of damage. It'd take just one N2 mine, for instance, to wipe them all out). I wouldn't be surprised if this idiotically dense formation made things worse when the inevitable Angel-related mayhem began.
thewayneiac: It's an entertainment thing; sort of the same principle as when they show the asteroid belt so densely packed that you could almost hop from one to another, when the average distance between asteroids is actually about 100,000 miles.
