Hull classification symbol (Canada)

The Royal Canadian Navy uses hull classification symbols to identify the types of its ships, which are similar to the United States Navy's Hull classification symbol system. The Royal Navy and some European and Commonwealth navies (19 in total) use a somewhat analogous system of Pennant numbers.

In a ship name such as HMCS Algonquin (DDG 283) the ship prefix HMCS for His or Her Majesty's Canadian Ship indicates the vessel is a warship in service to the Monarch of Canada, the proper name Algonquin may follow a naming convention for the class of vessel. The hull classification symbol in the example is the parenthetical suffix (DDG 283), where the hull classification type DDG indicates that the Algonquin is a guided missile destroyer and the hull classification number 283 is unique within that type. Listed below are various hull classification types with some currently in use and others that are retired and no longer in use.
