The Annapolis class destroyer escort was a class of ships that saw service with the Royal Canadian Navy and Canadian Forces from the 1960s-1990s. The RCN had intended to place a six ship order under the Mackenzie-class of destroyer escorts; however, the last two vessels were built to the St. Laurent-class DDH design and were classed under the new Annapolis-class designation. Both ships spent the majority of their career split between Canada's Pacific and Atlantic coasts with the Annapolis being at Esquimalt and Nipigon at Halifax.
