If the US Navy kept developing the Olympia line

What would the US Navy look like if it continued developing the USS Olympia design lineage?

It would likely field larger and faster cruisers that complement battleships and preserve global flagship and presence roles more cheaply.

The ships would become faster, larger, and more heavily armed as the Olympia lineage evolved. For the United States, investing in such cruisers could make more sense than relying entirely on a battleship program. Large cruisers could reinforce the battle fleet, serve as station flagships, and carry out worldwide cruiser missions at lower operating cost. Their survival into later decades might preserve those roles after battleships disappeared, although treaty definitions would still shape how far the line could develop.
