If ammunition capacity is the problem, why not build larger warships?
Short answerBecause larger ships cost more, make larger targets, and lose some basing and access options; magazine depth remains one part of a wider design balance.
NotesA viewer suggests that ammunition-capacity problems could be solved by building larger warships. Added size also makes a larger target and raises the cost of each hull. Bigger ships cannot use as many bases and may be unable to pass through some constrained waters or facilities. The design tradeoff sets valuable magazine depth against affordability, access, and the number of ships a fleet can sustain.
