Which modern ship comes closest to battlecruiser duties?

Is any modern ship performing battlecruiser-like duties by showing the flag and projecting impressive power below carrier scale?

The Zumwalt class comes closest in potential, though the comparison is about mission and presence rather than a literal return of the historic type.

The Zumwalt class is the closest modern candidate in potential without being a literal battlecruiser. Its size, distinctive appearance, sensors, and intended long-range strike role could make it a visible instrument of naval diplomacy below carrier scale. The analogy turns on mission and political effect rather than battleship armor or gun caliber. Because the class did not realize every planned capability, this remains a cautious analogy rather than a settled classification.
