Abstract : The Navy Clothing and Textile Research Facility (NCTRF) conducted physiological studies which established that the experimental Type B Submarine Deck Exposure Suit (SDES) prototype was a possible replacement for the Interim SDES currently worn on submarines. The Type B SDES prototype was then used as the basis for construction of the new Mod I SDES prototype, and additional Mod I prototypes were procured for further studies. Static buoyancy studies of the new Mod I SDES prototype and the Interim SDES revealed that the Mod I SDES provided an additional 9 pounds of buoyancy. Buoyancy studies of a human test subject wearing each SDES immersed in water indicated that the Mod I SDES had an increased buoyancy of 20 pounds. Each SDES was worn with insulated gloves and boots and the buoyancy of these items was included in each SDES's total buoyancy. The water pickup of the Mod I and the Interim SDES used in the man-in- suit buoyancy study was found to be equal, thus negating the need of the waterproof slide fastener used in the Interim SDES. Field evaluation studies indicated that the new Mod I SDES prototype provided more thermal protection than the Interim SDES when evaluated under wet, windy sub-freezing temperatures aboard Naval and Coast Guard vessels.
