The Nakajima B5N shows how Japanese naval aircraft designations worked. The letter marks the carrier-attack-bomber role, the number places it fifth in that design sequence, and the final letter identifies Nakajima as the manufacturer. Special and experimental categories required extra letters as aircraft appeared that did not fit the original labels. The codes offer a practical way to identify role, sequence, and maker while showing how the system accumulated exceptions.
