ELI5 why we stopped using large battleships.

Large battleships have the majority of their firepower in side mounted guns, which have a range of 15 km at most and can't shoot up. In contrast, aircraft carriers have an insanely long range and can shoot basically whatever. This gave aircraft carriers a huge advantage over battleships in World War II, to the point where the battleship-centered fleet model was rendered obsolete.

There actually is some speculation that having some battleships would make more strategic sense. But there haven't been any major naval battles since World War II to test this, and since the USA has more naval power than the rest of the world combined there won't be for the forseeable future.
