<p>I dont really know too much about it since I was fast attack other than the fact that there’s two crews and they alternate who owns the boat for 6 months at a time. This includes maintenance and underway time. It’s primarily on SSBN’s so they can maximize their operational time, but the SSGNs are doing it too for the same reason. It makes life a lot better from what I hear because you can knock out most of your training requirements when you’re in the off crew. It’s also 6 months you’re guaranteed to go home and sleep in your own bed at night which also is pretty nice.</p>
