Experimental diving in the US Navy started in 1912 at the Brooklyn Navy Yard under the leadership of Chief Gunner George D. Stillson. [1] Stillson's research program ultimately led to increasing diver capabilities from 60 feet (18 m) to over 300 feet (91 m) of depth based on Haldane's decompression work with the Royal Navy.
Royal Navy Northern and Southern Fleet Diving Groups and Fleet Diving Units 1, 2 and 3 are the clearance diving units specialising in various types of equipment and operations. Special Air Service Boat Troop is the Army special forces unit that undertakes water operations (emphasis of insertion onto land)
On February 16, 1965, United States Navy Divers Fred Jackson and John Youmans were killed in a decompression chamber fire at the Experimental Diving Unit in Washington, D.C., shortly after additional oxygen was added to the chamber's atmospheric mix. [46] [47]

Diving is a minor sport in India. Diving in India is administered by the Swimming Federation of India . Two Arjuna awardees , Bajrangi Prasad (1961) and Manjari Bhargava (1974) together with the Swimming Federation of India and the Army Sports Institute are working to uplift the sport in India. [ 1 ]
In July 1906, on board HMS Spanker off the west coast of Scotland, Rothesay, young Haldane jumped into the Atlantic Ocean with the experimental diving suit. The study was published in a 101-paged article in The Journal of Hygiene in 1908; where Haldane was described as "Jack Haldane (age 13)" for whom it "was the first time [he] had ever dived ...
The use of simple symmetrical exponential gas kinetics models has shown up the need for a model that would give slower tissue washout. In the early 1980s the US Navy Experimental Diving Unit developed an algorithm using a decompression model with exponential gas absorption as in the usual Haldanian model, but a slower linear release during ascent.
Experimental work by E.H. Lanphier at the US Navy Experimental Diving Unit indicates that: [1] Higher inspired oxygen partial pressure at 4 atm (400 kPa) accounted for not more than 25% of the elevation in end tidal carbon dioxide above values found at the same work rate when breathing air just below the surface.
