Montana, Iowa, and an enduring American doctrine

The Montana studies range along the battleship end of the capital-ship spectrum, while some Iowa paper variants approach the fast-battleship or even one-word battlecruiser boundary. Their roles preserve a consistent American logic rather than creating rival categories for their own sake. Montana supplies the heavily protected battle line intended to absorb punishment, return repeatedly, and deny an opponent a decisive result. Iowa provides the mobile component, updating the earlier South Dakota-Lexington relationship within a simple force structure designed to keep advancing across oceanic distances. The wider procurement lesson is that a simple doctrine consistently matched to national needs can be smarter than novelty because fewer moving parts leave fewer ways for a force structure to fail.
