With the growth of the U. Until , U. Navy divers rarely went below 60 fsw feet of seawater , and that was a real problem for submarine rescue operations. In that year, Chief Gunner George D. Stillson set up a program to test diving tables and methods of stage decompression. One goal of the program was to develop better Navy diving equipment as well.
Throughout the three-year program, divers went progressively deeper, eventually reaching fsw. As a direct result of the program, the first U. After World War I , diver-training programs were cut and the school was not reinstituted. The first divers to reach the submarine at fsw were able to make contact with the men trapped inside, but were unable to rescue them due to a hose connection that was feasible in theory but in reality could not provide the men in the submarine with oxygen.
The incident, along with other submarine accidents, sparked new interest in diving operations. The Naval School, Diving and Salvage, was re-established at the Washington Navy Yard during that year, and a rescue chamber that was essentially a diving bell with special fittings for connection to a submarine deck hatch was developed. By on 7 December , salvage teams were already at work cutting through the hull of overturned battle ship USS Oklahoma BB in an attempt to save Sailors trapped inside the ship.
Salvage operations were not the only missions assigned to Navy divers during the war. Many dives were made to inspect sunken enemy ships in an attempt to recover materials of intelligence value.
During the Battle of Okinawa , one UDT removed 1, underwater obstacles in two days, under heavy fire, without a single casualty. Navy diving, of course, is not limited to combat and salvage operations. Increasingly, a major part of the diving mission is the inspection and repair of naval vessels to decrease downtime, and the need for dry-docking. Other aspects include recovery and research of torpedoes, installation and repair of electronic arrays, underwater construction, and the recovery of downed aircraft.
The submarine and her crew sank to 8, fsw, a depth beyond the survival limit of the hull and far beyond the capability of existing rescue apparatus.
Three additional significant areas of improvement included saturation diving, the development of deep diving systems, and progress in advanced diving equipment design. Today, U.

One day, an ND might be in warm, clear, tropical water, and the next in cold, muddy water where their underwater tasks can only be completed by feel.
Navy Divers have been a stalemate of the US Navy since the middle of the nineteenth century. Surprisingly, however, despite their storied history, the Navy did not officially establish the Navy Diver, ND, rate until Eadie, although retired by the start of World War II, returned to duty to serve during the conflict.
The below chart indicates the minimum requirements as well as the automatic qualification scores:. Recruits accomplish this via successful completion of Navy Recruit Training, commonly referred to as Boot Camp. At the 7-week Preparation Course, NDs train in physical fitness, water adaptability, engineering studies, and electrical studies.
The training is 15 weeks long. Here they are further trained to perform underwater ship construction, salvage, and repair using either a surface-supplied-air diving system or SCUBA Equipment prior to deploying to the fleet. NDs may be entitled to other forms of compensation including base allowance for housing BAH , base allowance for subsistence BAS , and billet pay sea pay, submarine pay, hazardous duty pay, etc.
In simple terms, Navy Divers utilize a variety of diving equipment to perform a number of duties such as:. Navy Divers work in a variety of different environments, some of them quite extreme. Trained to do so, as an ND you may work in deep seas or shallow waters. You might find yourself in dark frigid arctic regions or in a clear-blue tropical ocean.
