In spite of the incredible technologic advances over the history of the U.S. Navy, the human operator continues to be the most important part of any system. The Littoral Combat Ship LCS concept proposed to reduce the number of sailors required to run a ship by leveraging new technologies. While the consequences of this manning decision are debatable, the effect of fatigue on a ships crew and their ability to perform is not. Using archival sleep data obtained from LCS-2, this thesis assessed the relationship between fatigue and crew member performance on the Psychomotor Vigilance Test and the Switching Test. While the regression analyses did not yield statistically significant results, the chi-square test showed that a significant departure occurred from the sleep obtained by LCS-2 crew members and the 480 minutes of daily sleep recommended in the NSWW. The effect of fatigue on a ships crew requires further research and a course of action is presented in the recommendations of this thesis that would help researchers obtain the necessary data for proper sleep study analyses.
