Building a balanced twenty-ship historical strike force

Which twenty or twenty-one historical vessels would you combine into a strike force?

For a general-purpose force, the proposed core is Implacable-class carriers and Iowa-class battleships, supported by Atlanta-class cruisers and Battle-class destroyers.

Any fleet choice depends on the operation and opponent. For a broadly capable twenty-ship historical force, the proposed core consists of Implacable-class carriers for useful air groups and armored protection, together with Iowa-class battleships for speed and surface power. Atlanta-class cruisers provide air defense, while Battle-class destroyers perform the remaining escort work. The exercise shows that fleet design depends on complementary roles and threat coverage rather than simply collecting the most individually powerful ships.
