Dominion torpedo craft depended on budgets more than design

Could the Dominions have built fast torpedo craft under 600 tons before the Second World War?

They could build useful coastal craft, but budgets, support costs, and competing fleet priorities would determine whether the programs became operational forces.

Small fast torpedo craft offered a relatively affordable way to threaten stronger ships near defended coasts. Dominion yards could build or assemble suitable vessels if a clear local requirement existed. The decisive obstacle was financial and institutional: governments had to fund crews, bases, maintenance, and training as well as hulls. British and local priorities could also divert limited money toward cruisers, escorts, or shore defenses with broader peacetime utility.
