If you want to "see the world" visit Europe and the Middle East go to a East Coast SSN or CVN.
If you want the kind of sea stories you don't tell in polite company go to a west coast SSN.
If you want to pull in anywhere outside the united states or canada don't go to a SSBN.
Both SSBNs and CVNs tend to have more predictable schedules.
note: I have never known anyone from a SSGN so I have no input in that regard
Haha...so true.
When I was in, we were all told that if you put in for a Carrier, you will get it and if you put in for a fast boat out of Hawai'i you will get it. I and two other guys in my prototype class put down ssn out of pearl as #1. The rest of the guys, as far as I know, put down everything in-between. Of us three that put ssn out of pearl, all three of us got it. The rest of those yahoos, with a few exceptions, ended up split between two CVNs.
Now, my personal feelings about ssn's having been a sailor on one is basically that is was cool for all of a week, and after that it was hell in a steel tube. A buddy of mine ended up (somehow, it's still not clear HOW) getting transferred from our ssn to a cvn after being on our boat for 2 years. When I saw him again, he wouldn't shut up about how much greater it was on a cvn, and how he can't imagine ever being on a ssn again.
I don't know if I would enjoy a CVN much, but I can sure agree with his sentiments about an ssn. Basically, try to overlook the "coolness" factor when you consider what you want, because that'll wear off pretty quickly when you get to your boat (even though, yeah, the navy will decide ultimately where you will go).
