When does a vessel carrying infantry become a landing ship rather than a landing craft or boat?
Short answerWhen its role expands from the local ship-to-shore movement to strategic transport and support of the landing operation.
NotesA landing craft conducts the ship-to-shore movement, although larger craft can also undertake a shore-to-shore passage. A landing ship transports a force over a strategic distance and then conducts or supports the landing. It may make the landing itself or carry smaller landing craft. Operational scope and capability define the distinction.
