The second batch of St Laurent class destroyers introduced design improvements found during construction. Late 1960s four ships of this class were refitted as Improved Restigouche (IRE) replacing the aft gun with an octuple antisubmarine ASROC launcher and the addition of a variable depth sonar. 1980s upgrades included the DELEX ( Destroyer Life Extension ) as her parent class. HMCS Terra Nova (DDE 259) was further modified during the 1990 Gulf War with Harpoon antiship missiles
