The US Navy ordered a ship named "USS" before the name "USS". Navy non-delegation, the name of the private ship begins with "USNS" and represents "US Navy Ship". The name of the ship is officially elected by the Navy Secretary and is usually used to commemorate important people and places. In addition, each ship has a character-based hull classification symbol (eg, CVN or DDG) to indicate the type and number of the ship. All vessels listed on the Navy list are registered in the Navy Ship Register, which is part of the "Naval List" (required by Article 29 of the United Nations Convention on the Law of the Sea). The registry keeps track of data such as current status of ship, commissioning date, date of discontinuation. Ships removed from the register before disposal are said to have been shot down from the register
