I think I can connect a couple of your questions.
DND and the CAF play a very important role in all of these projects, and the requirement-setting is done by DND. To the extent that DND has a view that two or three choices are adequate to serve and protect the CAF, it would articulate that. Only at that point.... It needs to be accepting of more than one solution if we can bring these other considerations to the table. It will have the last say on the requirements.
