Canada's navy changed and shrank in the latter part of the Cold War, but continued to face threats and meet alliance obligations. Despite the addition of some newer vessels, by the late 1970s it faced "rust-out" due to the gradual deterioration of ships and equipment.
This artist's concept for HMCS Iroquois shows a number of the ship's distinctive features, including its large helicopter hangar and twin funnels (centre).
The illustration shows some of the ship's anti-submarine weapons and sensors, including the helicopter landing deck and hangars (centre right), the Limbo anti-submarine mortar in its well (right), and the variable depth sonar equipment (far right). The first of four such anti-submarine destroyers to enter service in the early 1970s, Iroquois gave its name to the entire class (group) of ships.
