Warrior and Black Prince would overmatch the shogunate navy

How would HMS Warrior and HMS Black Prince be used if sent to support the Imperial side in the Japanese civil war, and could the shogunate deter them?

They would overwhelm the shogunate navy, which lacked ships capable of stopping or credibly deterring the two armored frigates.

The counterfactual sends HMS Warrior and HMS Black Prince to support the Imperial forces during the Japanese civil war. Their size, protection, and firepower lie well beyond what the shogunate navy could answer directly. The panel therefore sees no credible naval deterrent capable of stopping the two ironclads. Their presence would remove the shogunate fleet as an effective obstacle to Imperial coastal operations. The short exchange illustrates the extreme technological gap a first-generation ocean-going ironclad could create against a smaller transitional navy.
