Designed in the late 1950s and procured by Canada through a dynamic acquisition program in the early 1960s, the CH-124 Sea King helicopter has served Canadians with distinction since May 24, 1963.

Given the capabilities of a larger helicopter, crews could carry more armament, more fuel, and a suite of avionics—with capacity for growth. Considering the rapid advancement of submarine capabilities in the 1950s, the CHSS-2 became a potent counter-punch to non-friendly submarines. Over time, it proved capable of acting as an autonomous, multi-role ASW weapon system…
