GROTON, CONN. — With no sunlight to set day apart from night on a submarine, the Navy for decades has staggered sailors’ working hours on schedules with little resemblance to life above the ocean’s surface.
Research by a Navy laboratory in Groton is now leading to changes for the undersea fleet. Military scientists concluded submarine sailors, who traditionally begin a new workday every 18 hours, show less fatigue on a 24-hour schedule, and the Navy has endorsed the findings for any skippers who want to make the switch.
