What is a typical call sign for a large container ship under U.S. flag?

• A. KBZY
• B. WBX1469
• C. NADN
• D. KPH

Answer: (A)

A typical call sign for a large container ship under U.S. flag begins with the letter "W," which is designated for U.S. vessels. The portion that follows usually comprises a combination of letters and numbers that conform to specific requirements used to differentiate these ships in maritime communication. The format of a call sign is essential for identification in communication systems, especially under the Global Maritime Distress and Safety System (GMDSS). A call sign like "WBX1469" follows this U.S. convention, consisting of the prefix "W," which signifies the vessel’s nationality, followed by a mix of letters and numbers for unique identification. In contrast, call signs like "KBZY," "NADN," and "KPH" do not adhere to the standard format used for large container ships under the U.S. flag, as they either start with characters not designated for U.S. vessels or do not follow the numeric sequence typically found in U.S. maritime call signs.
