I understand completely.
We've had an exhaustive conversation here on shipbuilding and icebreakers. I've pretty much asked all the questions that I have on this project. They've been answered. Thank you very much for bringing your answers and insights here.
I want to ask some general questions for folks who might be watching the committee.
There's a universe of issues and subject matter that the PBO could study, and time and resources are limited. How does PBO decide what to study? What about this project got your attention, so to speak?
