How would one completed postwar Sovetsky Soyuz affect naval history?
Short answerIt would probably slow Western battleship retirements because several navies would retain ships able to meet it at short notice.
NotesThe scenario keeps one Sovetsky Soyuz in operational Soviet service well into the Cold War. Britain and France would then have reason to retain at least a few heavy ships rather than allow their capital-ship capability to disappear quickly. The United States would likewise keep additional battleships available. Because the Soviet ship might sortie at any time, opponents would need an active counter instead of assuming that a retired ship could be reactivated after a crisis began.
