Abstract
The keel for the first Canadian designed destroyer escort (DDE), HMCS ST. LAURENT was laid down 22 November 1950, launched November 1951 and completed 1955 followed in quick succession by six more ships of the DDE 205 Class. The 2900 ton DDEs were converted to DDHs commencing in 1962 with the fitment of a large hangar/flight deck complex for an operational 22,000 lb. Sea King helicopter. The last ship, HMCS FRASER, ended over four decades of reliable service by the 205 Class ships in 1994. This paper addresses the structural integrity of the DDH 205 Class over forty-three years in five distinct periods: (a) Eight years as a DDE, 1955-1963; (b) First thirteen years as a DDH, 1963-1976; (c) Two years prior to Destroyer Life Extension (DELEX), 1976-1978; (d) DELEX at twenty-seven years average age post launch, 1979-1982; and (e) Twelve year life after DELEX, 1982-1994. It is believed this is the first factual public record of the corrosion and structural problems experienced by a naval ship class over an entire ship class lifetime and life extension. Techniques developed to eliminate or at least retard such problems are presented.
