I don't disagree, now any changes are strictly because of normal design spiral changes. Suspect we'll still get small local changes as things go obsolete between now and build, but now down to space layouts.
Much more extensive then that though; our trade and the RAN trades are based on the RN trades; the AEGIS system certification is based around the USN operator/maintainer setup. We might end up smashing the CSE techs and Combat ops together to a certain extent. Honestly that work is about 5 years behind already with how brutally slow we are at the training review.
It's a sweet design though, but I think the additional watchkeeping requirement for AEGIS is going to kill the RCN. I also don't think we are prepared to maintain all the remote operation capabilities that you will need to safely operate the plant normally, when the MSED is down to 10-15% of the full crew complement. At least we convinced the crewing people a rounds person is still necessary, because that's how the systems are designed to be operated. If we let it degrade like we have the CPFs, and try and crew it with half the core people, we'll end up losing it to a normal peacetime event.
