A ship can already lag current technology by the time a long construction period ends. The new battleships will therefore enter refit as soon as they join the fleet instead of treating completion as the end of development. Real warships likewise pass through trials that expose defects and reveal changes needed for reliable operation. Post-trial work can correct those faults while installing the best equipment available before the ship begins sustained deployments.

Why new warships may need an immediate refit
An immediate in-game refit reflects the real gap between a ship's design date, trials, and entry into operational service.
