During wartime, what is the obligation of a flag state?

• A. Give up the vessel in the event of war
• B. Maintain sailing as usual
• C. Cease all trading operations
• D. Pay additional wartime duties

Answer: (A)

The main idea here is that during war the flag state must support its government’s needs for national defense, which can include requisitioning civilian ships for war purposes. When hostilities begin, the state may order ships under its flag to be placed under government control to be used for troop transport, cargo, or other military tasks. In that sense, the obligation is to give up the vessel if ordered, rather than insisting on normal commercial operation. This reflects the sovereign right of a state to marshal resources for national defense and is typically handled with some form of compensation to the owners later on. The other options don’t fit wartime realities: ships don’t continue sailing as if nothing changed, they don’t all cease trading, and paying extra wartime duties isn’t the flag state’s obligation about the vessel’s status in wartime.
