A British response to Yamato would be a fleet problem

The discussion argues that British or American forces meeting Japan would normally arrive as formations, not as a single ship accepting a one-on-one contest. That changes what counts as a credible response to Yamato: gun numbers, protection, and the availability of multiple ships matter alongside the quality of an individual battleship. The trial contrasts eighteen 18.1-inch guns with a much larger aggregate battery of 16-inch weapons, making volume of fire part of the comparison. It also frames a possible late Lion modernization as a force-structure choice rather than a purely technical answer.
