How the United States would answer World of Warships Satsuma

What does the panel think of World of Warships Satsuma, and how would the United States Navy respond if it existed?

Massing Essex-class carrier air groups would be the main answer, with a very large American battleship also possible if the threat were known early.

The fictional Satsuma carries four twin 510 mm turrets, heavy secondary batteries, substantial protection, and a meaningful anti-aircraft suite. The panel's primary American response is not a one-for-one gun duel but the mass production of Essex-class carriers and concentration of their air groups. If the Japanese ship were known early enough, the United States might also complete one or more very large battleships from its own design studies. The answer therefore combines industrial carrier warfare with a possible prestige and surface-combat response rather than relying on a single counterpart.
