Rebreather' Helps Navy Divers Beneath the Waves 31 May 2018, by Warren Duffie Jr
Deep breath: New 'rebreather' helps navy divers beneath the waves 31 May 2018, by Warren Duffie Jr. Panama City. The technology is sponsored by the Office of Naval Research Global (ONR Global) TechSolutions program. TechSolutions is ONR Global's rapid- response science and technology program that develops prototype technologies to address problems voiced by Sailors and Marines, usually within 12 months. "This rebreather system is an awesome opportunity to enhance the capabilities of Navy divers and accelerate their deployments," said ONR Command Master Chief Matt Matteson, who heads up TechSolutions. A US Navy diver gives the okay sign following his dive using the Office of Naval Research Global Navy diving missions include underwater rescues, TechSolutions-sponsored MK29 Mixed Gas Rebreather explosive ordnance disposal, ship hull system, which was developed at the Naval Surface maintenance, recovery of sunken equipment, and Warfare Center, Panama City Division.

HARBOR BRANCH FOUNDATION TECHNICAL REPORT No.21 , HISTORY ·One of the first written records of man's ability to work underwater is found in the writings of Herodotus in the 5th Century B.C. He tells of a diver named Scyllis who worked to recover sunken treasure for King Xerxes. There are many other accounts of divers working underwater by holding their breath for two to three minutes but it was not until 1500-1800 A.D. that any significant advancements were made which could be attributed to present day diving technology. During the period after 1500, a device called a diving bell came into the forefront as a practical tool to explore the underwater world. The device was called a bell because it resembled a typical church bell of the times. The first account of such equipment being used was in 1531. Bells did not advance much until the 1680's when an adventurer named William Phipps from Massachusetts supplied air toa bell by lowering inverted, weighted buckets of air to the divers. The famed astronomer, Edmund Halley, also developed a bell and demonstrated his system in 1690. Other inventions by various people were developed but were all like the first diving bells limited by the fact that air could not oe continuously supplied to the divers. It was not until the turn of the 19th Century that a hand oper ated air pump was developed which could deliver a continuous supply of air. -

Scuba Diving History
Scuba diving history Scuba history from a diving bell developed by Guglielmo de Loreno in 1535 up to John Bennett’s dive in the Philippines to amazing 308 meter in 2001 and much more… Humans have been diving since man was required to collect food from the sea. The need for air and protection under water was obvious. Let us find out how mankind conquered the sea in the quest to discover the beauty of the under water world. 1535 – A diving bell was developed by Guglielmo de Loreno. 1650 – Guericke developed the first air pump. 1667 – Robert Boyle observes the decompression sickness or “the bends”. After decompression of a snake he noticed gas bubbles in the eyes of a snake. 1691 – Another diving bell a weighted barrels, connected with an air pipe to the surface, was patented by Edmund Halley. 1715 – John Lethbridge built an underwater cylinder that was supplied via an air pipe from the surface with compressed air. To prevent the water from entering the cylinder, greased leather connections were integrated at the cylinder for the operators arms. 1776 – The first submarine was used for a military attack. 1826 – Charles Anthony and John Deane patented a helmet for fire fighters. This helmet was used for diving too. This first version was not fitted to the diving suit. The helmet was attached to the body of the diver with straps and air was supplied from the surfa 1837 – Augustus Siebe sealed the diving helmet of the Deane brothers’ to a watertight diving suit and became the standard for many dive expeditions. -

This is a unique and comprehensive summary of world wide development in this field. It is probably not realised what a vital part closed circuit breathing apparatus played in World War II. Apart from escapes from damaged and sunken submarines by means of the DSEA, and the special attacks on ships by human torpedoes and X-craft, including the mortal damage to the "Tirpitz", an important part of the invasion forces were the landing craft obstruction clearance units. These were special teams of frogmen in oxygen breathing sets who placed demolition charges on the formidable underwater obstructions along the north coast of France.
