The game records a partial penetration from an almost 21-inch projectile, a result questioned here as physically implausible. Such a shell could weigh close to three tons, depending on its construction and internal filling. Even without a clean penetration, that mass would deliver enormous kinetic energy together with a large explosive charge. The brief discussion distinguishes a simulation damage label from the scale of the real engineering problem facing armour designers. It also supplies physical context for the earlier super-battleship experiment.

What a 21-inch shell would do on impact
A simulated partial penetration prompts a reality check on the mass, explosive charge, and destructive energy of a near-21-inch naval shell.
