It is located within the Naval Support Activity Panama City in Panama City Beach, Bay County, Florida. Purpose The functions of the Navy Experimental Diving Unit are to test and evaluate diving, hyperbaric, and other life-support systems and procedures, and to conduct research and development in biomedical and environmental physiology. NEDU also provides technical recommendations to the Naval Sea Systems Command to support operational requirements of the US armed forces. History Brooklyn Navy Yard Experimental diving in the US Navy started in 1912 at the Brooklyn Navy Yard under the leadership of Chief Gunner George D. Stillson. Stillson's research program ultimately led to increasing diver capabilities from to over of depth based on Haldane's decompression work with the Royal Navy. This resulted in the first publicat ...

Momsen Lung
The Momsen lung was a primitive underwater rebreather used before and during World War II by American submariners as emergency escape gear. It was invented by Charles Momsen (nicknamed "Swede"). Submariners trained with this apparatus in an deep Escape Training Tank at New London, Mare Island, or Pearl Harbor. It was introduced as standard equipment on ''Porpoise'' (P)-class and ''Salmon''-class boats. The device recycled the breathing gas by using a counterlung containing soda lime to remove the carbon dioxide. The lung was initially filled with oxygen and connected to a mouthpiece by twin hoses containing one-way valves, one for breathing in and the other for breathing out. The only known emergency use of the Momsen lung was during the escape from on October 25, 1944. Thirteen men (of thirty survivors) left the forward escape trunk: five were picked up by the Japanese; three more reached the surface "but were unable to hang on or breathe and floated off and drowned"; the ...
