About thirteen full salvos from an eight-gun battleship could put a roughly 1,850-ton Tribal-class destroyer's displacement worth of shells into the air, by a rough calculation. The comparison is intentionally illustrative rather than a firing formula. Heavy-gun ammunition consumption quickly becomes an industrial and logistical problem.

A rough comparison turns shell weight into fleet scale by asking how many battleship salvos equal the mass of a Tribal-class destroyer.
