I'm going to ask the as-of-yet unasked question.
Why do you want to be an officer in the United States Navy?
This is important because as a Nuke SWO (Surface Warfare Officer) who stays beyond their carrier Division Officer tour, approximately 3/4 of your career will be in non-Nuke billets. Also, your job as an officer is to be a leader for the division, run the programs your division is responsible for (i.e. planned/preventive maintenance, approving personnel evaluations, assigning personnel responsibilities, etc.), generally the non-Nuke activities that the rest of the Navy does on a routine basis.
I'm not asking to try and tell you that you are looking in the wrong career field; I ask because I get the feeling that you don't have a good, solid idea of what a commissioned officer does in the in Navy, other than get paid more than most of the enlisted sailors.
I'm also not sure that you are mature enough, at the age of 19 (when you graduate college), to be a Division Officer. Yes, that is a generalized statement based on a stereotype. I make it based on what I dealt with as a Division Chief and my sailors who were 19 years old.
Gather as much info as possible. Do NOT sign an enlisted contract or pursue a Nuke officer position thinking you will be performing engineering work; that's not what Navy nukes, enlisted or officer, do. Navy Nukes operate and maintain the propulsion plant aboard aircraft carriers and submarines, facilitating placing ordnance on station before the bad guys can do the same to us
Best of luck to you as you figure out what is best for YOU!
