It will depend on the rate (job) you pick and where you are stationed. You could go to a ship that is being built so you don't go anywhere. you could get assigned to shore duty at an Overseas location and still not go anywhere. You could go IA to Djibouti, Afghanistan or Iraq. Or you could be assigned to a ship that is constantly out to sea. Even those deployments will range from a few days to weeks to months to over half the year.
