OK, someone more current correct me if I'm wrong, but if I had anyone come up to me on the street tomorrow and tell me they were quitting NROTC and applying to OCS for an aviation slot, I'd tell them they were on crack, and to put it down and sign the drug waiver. USNA and NROTC are the Navy's two guaranteed sources for every year's quota of unrestricted line officers, whatever BUPERS says that is. Whatever's left gets filled in at OCS. So for a given year group, if you want an aviation slot, your best bet is to start early and get in NROTC or (God forbid) USNA. Otherwise, you're fighting over the scraps that NROTC and USNA couldn't fill for whatever Big Navy's quota was that year.
And if you want to be a fighter guy, great. So did a whole bunch of 18-year-olds before you (including me before I discovered Prowlers. I wanted to be a Tomcat guy when I commissioned; I got better later on). Set yourself up for Plan B and Plan C. In other words, what other platform do you want if you can't be a fighter guy? And what college major do you want if you can't serve period? That way, if you get fighters, great. But if you change your mind, don't make the cut, or get screwed over by the bureaucrats, you've still got options. Don't set yourself up to be that guy who's bitter about not getting jets, or not getting fighters, AF or Navy. That guy is a huge self-centered douche, and nobody likes him. Heck, nobody likes the fighter guy who's a huge self-centered douche, either. Movies aside, humility is a thing. Confidence != arrogance.
