How We Build the Arctic and Offshore Patrol Ships

Irving Shipbuilding uses a progressive build approach to construct the AOPS. Over the course of time, 63 smaller units become 21 larger blocks, which become 3 mega-blocks. We will use the same progressive build approach for the Canadian Surface Combatants.

Mega-block Arrangement

Construction in Progress

The first keel unit of the future HMCS Harry DeWolf, sits in the cradles at Halifax Shipyard.
The base of the main keel unit of the future HMCS Harry DeWolf comes together.
Units are stacked on top of the main keel unit to form a mega-block. This is the first of three mega-blocks of the future HMCS Harry DeWolf.
Progress continues at Halifax Shipyard with another level added to the mega-block.
