Did ammunition count toward treaty displacement?

Did a warship's ammunition count toward its standard displacement under the naval treaties?

Yes, although declared loads could understate the magazine capacity a ship was actually designed to carry.

A viewer asks whether the thousands of shells in the comparison would count toward standard displacement. Ammunition did count, although navies did not always report treaty figures candidly. A ship could declare one normal load yet possess magazine space for substantially more rounds. An autoloader's rate could therefore force designers to trade treaty weight against the hidden volume and capacity needed for useful endurance.
