This has significantly changed in the last 5 years. Pilots are now being much more integrated into mission execution. When teaching at the rag 2018-20 I definitely noticed the "iron cockpit curtain" when flying with native E-2C Pilots (I'm a native E-2D dude). ICS improvements and community mentality has led to a significantly more integrated crew. Hell, they were in the early stages of a T-4O (tactical fourth operator) syllabus for pilots when I was there.Caveat that I’ve been out of the E-2 world for a while so my info’s a bit dated, but I flew the Hawkeye 2000 birds in the Fleet and E-2D in flight test. The division of crew duties in the E-2 is pretty stark. The pilots don’t do much “mission” stuff and the FOs don’t have much to do with flying the plane. The former part may have changed with the D’s Tactical Cockpit - the pilots have the ability to bring up a mission display and they have a kneeboard with trackball and keyboard - but since they aren’t trained AICs they can “see” a lot more than they can “do”.
I liked being an AIC but I wish I’d known that as a Hummer FO most of the fun parts of flying you get to experience is limited to what you can see peeping through the little window in the back around the starboard nacelle. By the same token, I’ve known some E-2 pilots who felt kind of bored not being involved in the actual mission (most of them are happy to leave the nerd shit to the Trunk Monkeys, though) and the only “tactical” thing they do is flying around the Boat.
That said, the D is pretty cool. It can actually do what NGC promised it’d be able to do, the weapon system is light-years beyond what the APS-145 planes could do.
