Could the Queen Elizabeths defeat Yamato together?

Would all five Queen Elizabeth-class battleships together be enough to defeat Yamato?

Probably, but only at severe cost, with most of the British squadron likely lost or badly damaged.

Five Queen Elizabeth-class battleships could probably defeat an isolated Yamato through combined heavy-gun fire, but the result would be ruinously expensive. The answer imagines most of the British ships being lost or badly damaged before the last survivor finished the engagement. This is a deliberately narrow ship-against-squadron counterfactual, separate from the earlier warning that Yamato would normally operate with escorts and other capital ships. Concentration supplies the necessary firepower, yet it does not make the matchup efficient or safe.
