Mackenzie class destroyer escorts - Making good with what you got

Background & History

The Mackenzie class destroyer escorts were a class of 4 destroyer escorts built by Canada in the 1950’s and were the successors of the Restigouche class destroyer escorts, these ships were the 3rd iteration of the St. Laurent class destroyer escorts which were the first major warship designed by and built in Canada, the St. Laurent brought many elements which made them good vessels however within a decade the class would rapidly evolve as half of the St. Laurent class were cut and reordered to an improved version which was the Restigouche class and following that class was the Mackenzie class which was to be a more advanced design however in the end the Mackenzie class remained in its close ties to the St. Laurent class as what started out as a class meant to be one of Canada’s answer to fill the role of ASW in NATO turned out 4 new classes total.

The Mackenzie class was originally planned to be a new design which included stronger machinery which produced greater power as well as be larger than the previous ships while retaining the same abilities, however despite the class originally supposed to be the next major design which improved on the previous ships but due to problems with the budget of the program the Mackenzie class was instead had to be built as repeats of the Restigouche class though affording to make some improvements. Even the total of ships came out to have problems as a total of 6 ships were ordered but in the end only 4 were completed as Mackenzie class vessels, the last 2 were instead reordered to similar specifications of a modernization which was in the works for the St. Laurent class which installed a helicopter and accompanying hanger and this class was the Annapolis class, even the last ship of Mackenzie class was completed differently as HMCS Qu’Appelle used only American 3 inch guns rather than the mix of British and American guns, granted due to the guns finally being unavailable at that point. The class itself entered service in the 1960’s however in service they would receive minimal modernizations beyond the DELEX modernization of the 1970’s which extended the service lives of the St. Laurent, Restigouche, Mackenzie, and Annapolis class as they received more modern systems to allow them to deal with modern soviet submarines as they were some of the last steam powered vessels in Canadian service and were extended in their service lives while awaiting their replacements, however in the case of this class they were at that point the least capable of the 4 classes as they had originally Limbo mortars and torpedo tubes which could be used for ASW, however all the other classes had some element which was included to allow them to be capable of effective ASW against modern submarines such as the helicopters of the St. Laurent and Annapolis class, and the ASROC on the Restigouche class however the Mackenzie class at best received better torpedos in service but in the end the Limbo mortars were removed due to how old they were, due to their lack of major modernization they were primarily used as training vessels rather than the other classes but remained in service until the 1990’s.

The ships themselves were armed with 4 3 inch guns in 2 twin turrets, normally this would be in the form of 2 3 inch/70 Mark 6 British built guns and 2 3 inch/50 Mark 22 guns in a Mark 33 turret however in the case of Qu’Appelle she only had the 3 inch/50 guns (as seen in the second image), the ships also had 2 Mark 4 Limbo anti submarine mortars located at the rear of the ship, they also had the provisions for 2 single Mk.2 “K-gun” launchers whited used homing torpedoes however they may not have been used in service as the other classes also at points had provision for these but never used them so it’s uncertain if these were used ever, later on however the K gun launchers were replaced with 6 12.75 inch (324mm) Mark 32 torpedo tubes in 2 triple mounts and by the 1990’s the Limbo mortars were removed however retained their original gun armament.
