Very briefly, I think there's potential value there in at least three ways.
First is any economic spinoff from the domestic economic activity, which you would offset against any price difference somewhere else.
Second, having a domestic shipbuilding industry is important for sustaining whatever ships you build, and you want to maintain that capability.
Third, in terms of exports, we have already seen, though not on the NSPS, the national shipbuilding procurement strategy, component, at least one major announcement about the export of some of the technology that went into the upgraded Halifax class frigates.
