WWII sparked a second rush by allied countries for ships. As opposed to the Great War of 1914-1918, this time the theatre for war was primarily at sea which meant Davie had to produce more sophisticated vessels to combat the new threat. Davie built over 60 ships during this short period for the Canadian, British and French navies. These included corvettes, frigates and landing craft for active operations as well as minesweepers and auxiliary ships to support the navies and merchant shipping fleet.
