A modern battleship built around power, railguns, and missiles

What would a battleship designed with current and near-future technology look like?

It would be a heavily protected power-and-magazine platform with long-range railguns, roughly 240 missile cells, layered laser and gun defenses, and extensive crewed and uncrewed aviation.

The concept uses three twin railgun mountings around 9.2-inch caliber, aiming for roughly 250 to 300 nautical miles of gun reach. About 240 vertical-launch cells provide flexible missile capacity beyond the railguns' envelope. Lasers and 40 mm or 76 mm weapons supply closer defense, while helicopters and uncrewed aircraft extend sensing and targeting. Heavy protection concentrates on power plants, magazines, and vital systems, with modular propulsion intended to keep an electricity-intensive ship maintainable.
