 Welcome to All Hands Update, I'm Petty Officer Ian Cotter. The Office of Naval Research has developed a safe and highly efficient, electrically heated thermal undergarment to keep divers warm. Since the 1960s, the U.S. Navy has been researching diver thermal protection. The research conducted at Naval Surface Warfare Center in Panama City, Florida compares the new suit to the currently used dry suit. The undergarment uses new technology, generating lower power than other available suits. Because salt water has a lower freezing temperature than fresh water, ocean temperatures can drop as low as 29 degrees Fahrenheit. Operating in these cold temperatures can lead to loss of muscle strength and the ability to operate tools. The suits are being tested to work in both wet and dry environments and for other specific missions. For more information, visit the Office of Naval Research website.
