How another decade of peace transforms the major navies

What would the major navies look like if general war were delayed until 1949?

They would be far newer and more capital-intensive, provided Japan found a way around the resource crisis that historically forced its hand.

The premise requires Japan to avoid the resource and industrial trap that made prolonged peace difficult by the early 1940s. If it does, more Yamato derivatives or super-Yamatos might appear, though Yamamoto could press for a greater carrier programme. France would continue developing Richelieu-like capital ships, while Soviet construction would depend heavily on Stalin's preferences. The British and American fleets would replace many First World War and interwar hulls, leaving force structures that looked very different from those associated with the historical Second World War.
