Why Australia designed Bathurst-class corvettes

How much is known about Canadian and South African defence science during the Second World War?

Much of it was integrated with Britain, while Australia developed enough naval-design capacity to create the Bathurst class for its own needs.

Canadian and South African defence science was heavily integrated into the wider British imperial system. Canadian and South African governments had invested little in independent research systems. Australia had built enough naval-architecture capability to produce an independent design. Its yards could also use better machinery than the deliberately simplified Flower-class approach. Australian distance and concern about Japanese minelaying pushed the Bathurst class toward requirements distinct from North Atlantic convoy escorts.
