E-Guard: Expediting Submarine Escape Time Calculations
Abstract
When faced with a distressed submarine (DISSUB) scenario, Sailors rely on the DISSUB Guard Book to make decisions about whether to await rescue or attempt an escape. Unfortunately, a 2020 preliminary research study demonstrated that performance on Guard Book-required calculations is poor, with only about 50 of individuals arriving at the correct answer. The current study tests whether an electronic version of the Guard Book (E-Guard) may help Sailors overcome some of these calculation errors. Forty-five active-duty submariners completed escape time calculations using either the paper Guard Book or the E-Guard; calculations were conducted both in an unstressed, laboratory environment, and in a classroom immediately upon completion of an emergency training simulation in the Damage Control trainer. Submariners were significantly more accurate and completed the calculations significantly faster when using the tablet-based E-Guard compared to when using the traditional paper version of the Guard Book. Recommendations for how to improve performance on both paper Guard Book and E-Guard platforms are provided.
