ABF? Yikes, that's miserable work. That's "purple shirt" work in the flight deck. You'll never get the stink of JP-5 off yourself. Flight quarters can be set before dawn and go on all day and into the night. It's hot and dangerous work. I don't know what your ASVAB scores look like, but if you want a sure shot at sea duty, and a good job while doing it, try something like Sonar Tech (surface), Quartermaster or Operations Specialist. Even Gunner's Mate will get you on sea duty with good working conditions. Don't worry, you're going to see plenty of the world.
