| Description | LC-DIG-HEC-24896: “Depth of 500 feet reached by U.S. Navy Divers in recent test of Helium-Oxygen for air supply.” Record dives – deep as 500 feet – have been recently made at the Washington Navy Yard and off USS Falcon submarine rescue off Portsmouth, New Hampshire, by divers using U.S. Navy standard diving suits and with a mixture of helium-oxygen for air supply. A depth of 500 feet was reached under simulated sea conditions in the diving tank. Heretofore, 306 feet was the greatest depth reached by divers wearing standard rubber diving suits. Ship-Fitter First Class H.H. Frye, USN, takes a sample for analysis from the helium bottle after mixing gas with oxygen in preparation for dive in tank. Photographed by Harris and Ewing, August 9, 1938. (8/7/2015). |
