St. Laurent class Destroyer

First major warships designed and built in Canada were similar to the British Type 12 Whitby class but with American equipment. They were refitted from destroyer escorts (DDE) to helicopter-capable ships (DDH) in mid-60s. All but St. Laurent received a second refit during the 1980s known as DELEX ( Destroyer Life Extension ) which give them new electronics, machinery, and hull upgrades. 14 ships were planned but production shift to the Restigouche_class after the seventh unit.
