The kind of accident any organization should worry about is the one that seems impossible. In 2017, the U.S. Navy was rocked with two collisions at sea. These tragedies resulted in the combined deaths of 17 sailors. While both collisions were under different circumstances, and in-depth investigations remain ongoing, these events have triggered a service-wide review of the demands placed on surface warfare officers, including manning, sleep deprivation, and rising operational tempos. This article examines the way in which the Navy assigns officers to its surface vessels., and suggests improvements that could mitigate future collisions at sea.
