Carriers do not deploy for 12 months. They can be deployed over 6 months at a time, but then when you add in workups, trials, and exercises it can add up to be gone over 80% of the year. The time when there was 18 months between 6 month deployments is now gone, you can be deployed at any time for a long length of time. These days they are out for 6 months, in for a few, then back out again. When you come back from a long deployment you will have stand down where you only have to be in for a few days out of several weeks. But then will be back on teh regular schedules of 7:30 to 4:30 Monday to Friday plus duty days.
