Blocks, tackles, and other shipboard gear could move heavy rounds between magazines and guns without asking crews to carry every load by hand. The ammunition traveled with the warship instead of requiring horses, wagons, roads, and a separate supply column. Naval designers could therefore use much larger shells, while a mobile army had to balance projectile power against the burden of transporting guns and ammunition overland. The comparison shows how the transport platform shaped artillery design as well as supply.

Why ships could carry heavier shells than armies
A ship's tackles and floating transport capacity let naval guns use ammunition that would be far harder to move with a field army.
