The kanji 艦 is a phono-semantic compound (形声文字, keisei moji). The left side is the radical 舟 (ふね, fune), meaning "boat" or "ship." The right side is 監 (かん, kan), which means "to supervise" or "to oversee." Therefore, the character depicts a ship (舟) that is being supervised or commanded (監). Over time, the meaning evolved to represent a warship or a ship of the navy because these were the vessels typically under the command of a fleet commander. The development reflects how the character became associated with military vessels.
