No hard feelings.
I was going to go into the differences between officer and enlisted training and the differences in their jobs, which would be easy to do in a face to face discussion, but difficult to word correctly on a public forum without it being misinterpreted or taken as an insult by both sides of the fence.
Against my better judgment, I'll try to generalize:
You are correct that no officer will ever know as much about RC division equipment as the RC division chief/LPO. Same goes for every other division.
I would say "in general" officers get more crosstraining and integrated plant operations training and experience than enlisted (ie the typical RC div guy probably doesn't know as much about seawater or lube oil systems as an officer, or the typical officer knows much more about RC div equipment than the typical mechanic, etc). At prototype, the o-gangers had to stand every watch in the plant multiple times.
I'd also say, "in general" that officers delve much more into theory, calculations, etc. I've known many prior-enlisted officers. Without exception, they tell me the officer pipeline was much harder than the enlisted pipeline. As example, in my commercial SRO class, we were given an NRC fundamentals pre-test prior to being taught the material in class, just to see where we stood. The entire class was prior navy, with the vast majority prior enlisted. Only 2 guys passed the test: one held an RO licence at another commercial plant, the other was a recently separated officer (the officer scored the highest in the class).
What does all this mean?...absolutely nothing! Could a bunch of officers start up the reactor on their own...probably. Could they start up the engine-room on their own...highly doubtful. Could they maintain or repair any of the equipment...even more doubtful. Everyone has their own part to play, and their success both in the navy and in the commercial world depends more upon their own work-ethic and judgment...neither of which is unique to officers or enlisted.
I have an enormous amount of respect for enlisted nukes. The crap they put up with compared to their financial compensation would be hard to comprehend were it not for love of country or other reward. They are almost without exception, extremely intelligent and could make much more money elsewhere.
Hope I did not offend anyone with my generalizations. If so, it was not my intention.
