The upgraded Mogami is heavier while retaining roughly the same engine power. Quoted displacement rises to about 4,800 tons standard and 6,200 tons fully loaded. The stated increases are around 900 tons standard and, more tentatively, 700 tons at full load; the standard-displacement increase does not exactly match the earlier rounded baseline. Range remains good in this assessment, although no numerical range is supplied. A thirty-two-cell Mark 41 battery doubles the sixteen-cell baseline used earlier.
