The British Mark VII Submarine Escape Immersion Suit SEIS which provides thermal protection and the Steinke Hood which does not, were evaluated for single-man and group escape 2- and 3-man teams from a simulated top egress United States Navy escape trunk. For both escape appliances, egress time increased linearly as a function of team size. Three-man teams and two-man teams escaped faster with the SEIS than with the Steinke Hood there was no difference for one-man escapes. Single-man escape times with the SEIS were comparable to those obtained by the British. When compared with side and tube egress, top egress offers a substantial reduction in escape time and therefore in total bottom time. Safe escapes from depths in excess of 450 feet by teams of more than two men are feasible from a top hatch configuration but are not possible from a side or tube egress configuration. A submarine escape system employing top egress and the exposure protection of the SEIS is recommended.
