You are all healthy young men, but you are not getting any physical exercise. You are not going topside to get some fresh air and see the ocean. As a nuclear sailor you will never see the sea. You work, sleep and live your entire time at sea in a factory without windows, a building without doors to the outside world. Sprinkled throughout this day we may also go through various drills.
Battle stations is an all hands evolution so everybody is up and at their assigned stations.
The routine seldom varies day after day, week after week. You never see light at the end of the tunnel. As a machinist you are not involved in the excitement of the chase that might be going on in the attack center. The duty officers, fire control people and the sonarmen are doing that. They are tracking the target and making calculations about how to get into the right position to score a certain kill.
