Alaska as the heavy cruiser taken to its wartime limit

How should the Alaska class be understood within cruiser classification?

As the scale and capability a heavy cruiser could plausibly reach by the Second World War.

The Alaska class is the logical wartime expansion of the heavy-cruiser idea. Its guns, speed, and scale exceeded treaty cruisers without making the ship a conventional battleship. Once treaty-era limits no longer fixed the design envelope, a heavy cruiser could grow toward this level of capability. The classification is therefore an argument about design lineage and intended role rather than displacement alone.
