The campaign waits a month for imminent technology that can be incorporated into the initial battleship design. That choice avoids beginning construction with systems already known to be obsolete when a short delay can prevent it. Even so, radios, fire control, armor, and other equipment continue advancing during a capital-ship build of roughly two years. A launch-day refit is therefore treated as inevitable, using the much shorter modernization period to bring the completed hull up to the standard reached while it was under construction.

Long builds make launch-day refits inevitable
Research is delayed briefly so new ships start with better systems, yet a two-year battleship build still guarantees further upgrades before service.
