I think that it is becoming clear that the program keeps getting softer and softer and apparently so are the baby nukes. If someone can't survive power school from being on 35-5's saying they need more free time there is no way they would survive on a submarine. I studied for 40 hours a week and had more than enough time to PT at least 4 times a week and get kind of crazy on the weekends. Being a nuke on a submarine takes mental toughness. In my opinion is prototype absoltely necessary, probably not. However it puts young sailors in stressful situations to weed out more people that can't handle the fleet. It also provides shore billets for guys that want to stay in the Navy. I'm positive not many people could survive 20 years straight out at sea though I have seen it before. The CMC in NY when I was there was on his first shore tour and he had been in for like 25 years. If you are at sea on a sub you can expecto to be on the boat (including duty) for at least 80 hours a week. Enough to make you wish you were actually at sea because it is just easier to know that you arent going home. Enjoy the pipline folks, it just gets harder after that.
