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.
HMCS Nipigon, built in the early 1960s, was rebuilt in the early 1980s and remained in service until the late 1990s.
Nipigon, which entered Canadian service in 1964, was modified during its construction to accommodate the helicopter facilities (centre and centre left) and variable depth sonar (far left) that was being retrofitted to other Canadian ships. In the late 1970s and early 1980s, Nipigon was one of the Canadian ships selected for a destroyer life extension (DELEX) program that replaced electronics, machinery, and weapons, and upgraded and repaired the ships' hulls.
