Summary[edit]

Summary
Description	330-PSA-262-63 (USN 711388): The Steinke Hood, an air inflatable escape appliance for use by submarine personnel, was developed by Lieutenant Harris Steinke at the U.S. Naval Submarine School, New London, Connecticut. The hood is attached to a submarine life jacket. Expanding air from within the life jacket passes through the hood to ventilate it and keep it expanded during the ascent. The escapee, with his head in the hood, has enough air available to breathe normally during his ascent. Photograph released November 14, 1963. (2015/10/27).
