SUBMARINERS offers a "day in the life" of a submariner and profiles the amazing teamwork constantly performed, particularly in the nuclear sub, where safety is of vital importance. On a modern nuclear submarine, the distinction between night and day becomes a blur. Isolation, confinement, lack of privacy and intense pressure mark an endless cycle of six hour shifts. It is a world punctuated by constant attack readiness drills, tracking exercises and system checks. A world in which man no longer simply operates the weapon, he lives inside it, plotting the solutions and piloting the vessel on the most secretive of all military missions.
