Full displacement is a measure of a naval ship's size.

The ship is complete and ready for service in every respect, with liquids in machinery at operating levels; authorized complement of crewmembers and their effects; full allowances of ammunition, provisions, and stores for ship's own use in tanks to full capacity; and cargo, dunnage, passengers, and supplies other than for ship's own use in amounts that will bring the ship to its limiting draft or legal load line.
