This event, attended by notable figures including Robb Wight, Director General for Vessel Procurement of the Canadian Coast Guard, Rear-Admiral Josée Kurtz, and the Hon. Sean Fraser, signals the initiation of a significant vessel designed for a variety of missions from fisheries enforcement to search and rescue in the Arctic region.
The National Shipbuilding Strategy has commissioned Irving Shipbuilding to construct a total of eight AOPS vessels, six for the Royal Canadian Navy and two for the Canadian Coast Guard, as well as 15 Canadian Surface Combatants. With the first three AOPS already in service with the Royal Canadian Navy, the upcoming vessels are on track for delivery in the next few years.
The strategy aims to bolster Canada's naval capabilities while stabilizing the nation's shipbuilding industry, enabling Halifax shipbuilders to enhance their expertise and reinforce vital supply chains. This effort ensures the safety of Canada's naval forces and strengthens Canada's international security presence.
