An extra battleship at Denmark Strait or in the Mediterranean

What effects would the hypothetical Subjugator have at Denmark Strait and in the Mediterranean?

It is expected at Denmark Strait first, where its heavy guns would threaten Bismarck, with a possible later Mediterranean deployment against Littorio.

The hypothetical battleship Subjugator is considered more likely to be available at Denmark Strait than in the Mediterranean. Other ships could cover the Mediterranean requirement in the scenario. Its heavy gunfire is expected to make the engagement much harder for Bismarck. A later Mediterranean deployment would pose a comparable threat to Littorio. These are conditional judgments about the imagined deployment, without a detailed reconstruction of either battle.
