Three Royal Canadian Navy ‘Tribal’ class destroyers (from left to right), Nootka, Haida and Micmac, seen in company with three of the new, St Laurent class destroyer escorts at Oslo, in the late 1950s or early 1960s. It’s interesting to note how the apparently lightly-armed, post-war vessels are significantly bigger than the ‘Tribals’, the Royal Navy’s largest destroyers for most of World War II.
