His/Her Netherlands Majesty's Ship
From Wikipedia, the free encyclopedia
His Netherlands Majesty's Ship (Dutch: Zijner Majesteits, literal translation: His Majesty's) or Her Netherlands Majesty's Ship (Dutch: Harer Majesteits, literal translation: Her Majesty's) is a ship prefix of the Royal Netherlands Navy for naval ships commanded by an officer. The English abbreviation for both prefixes is HNLMS (Dutch: Zr.Ms. or Hr.Ms.). Sometimes HNMS is used, but this could also mean Norway. One way to avoid the ambiguity of HNMS is to use "HNLMS" for the Netherlands and "HNoMS" for Norway.
