The Army views and handles aviation much different than the other services, seeing it largely as something to support the rest of the service and not a tool that can work independently. Their pilots are just as skilled as any other in the US military but they really don't get involved in the larger air campaign and their skill set doesn't generally include it. That is reflected in the composition of their aviator corps, which is predominantly CWO's and not regular officers. That is the most basic reason CWO's won't work very well in larger Naval Aviation.
There is a large chunk of Naval Aviation that is a support role.
I would say all of rotary, a good chunk of Maritime (because flying ISR tracks does not take a genius), C-2’s, TACAMO, and UAV’s could all be a relatively low impact switch.
The E-2 would be doable up front, leaving your tube slugs as URL...
I don’t think fiddling with the Rhino or Growler cadre would be a good idea.
I flew with multiple CWO’s in 46 and they were, for the most part, really good. The only issues I saw were the same you get from the prior-E’s that couldn’t let the past go...and we have plenty of those in the URL side of the house.
I still believe the Brits do it right, with a career/command track and a non-command track...
