So why do people go SWO over Subs if they are both stressful?
The money seems to even out (75k bonus for 4 years vs. 20-25k/yr for 5 years). Is it just a personality thing? The math?
The bonuses for nuke are higher than the bonuses for being a conventional SWO, both on the sub and SWO side. Also, submariners get sub pay in addition to sea pay, so we make more during our first tour. However, the bonuses that nuke SWOs get for signing a second 5 year contract are higher and essentially make up for that difference.
Honestly, though, money didn't really factor into my decision to go sub nuke. I went to the recruiter telling him that I wanted to apply for it, and he suddenly started spouting off all this money the Navy was going to throw at me for doing something I wanted to do.
non-nuke SWOs generally don't work on carriers and never attend nuke school. Your career is geared entirely toward command of a ship.
nuke SWOs split their tours between what a non-nuke SWO does and engine room on CVN. In other words, you'll do your first sea tour, get your pin. Then you go to nuke school, and instead of doing your second sea tour on any ship you choose, you'll work in the engine room of a CVN. This dichotomy of jobs continues throughout a SWO/N's entire career. For example, when you screen for XO, you will screen for both XO of a conventional ship, doing normal SWO XO stuff, and you will also screen for XO of the engine room on a CVN.
For submariners, it's the opposite -- you work your way out of the engine room rather than into it. The first thing you do is qualify EOOW, then you move onto other sections, qualify as OOD, and earn your dolphins. Your DH tour might be as the eng, but it might be as the ops or nav officer, in which case you don't do much nuke stuff at all.
