A British 9.2-inch heavy cruiser and its rivals

What if Britain built a 9.2-inch heavy cruiser in 1937-39?

It would likely accelerate rival large-cruiser programs and become a major Royal Navy fast-fleet asset.

The likely British configuration uses three triple 9.2-inch turrets in a compact capital-ship-style layout. Such a ship would sit above treaty heavy cruisers without requiring a full battlecruiser. Germany would have to reconsider the safety of the Deutschland class, Japan might accelerate its own heavy-cruiser response, and the United States could bring the Alaska program forward. For Britain, the result would be a powerful fast-fleet combatant able to alter calculations around older and smaller ships. Real Royal Navy investment still had to prioritize the carrier program, so this attractive cruiser should not displace aircraft-carrier construction.
