Many dives were made to inspect sunken enemy ships in an attempt to recover materials of intelligence value. Salvage operations were not the only missions assigned to Navy divers during the war. By 0915 on 7 December 1941, salvage teams were already at work cutting through the hull of overturned battle ship USS Oklahoma (BB-37) in an attempt to save Sailors trapped inside the ship. Navy divers plunged into World War II with the Japanese attack on Pearl Harbor. The apparatus, called the McCann-Erickson Rescue Chamber, was proven somewhat effective in 1939 when it was used to rescue the crew of USS Squalus (SS-192) that suffered a catastrophic valve failure off the Isle of Shoals.
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. The incident, along with other submarine accidents, sparked new interest in diving operations. The first divers to reach the submarine at 102 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. In 1927, USS S-4 (SS-109) was lost in a collision with the Coast Guard cutter USS Paulding. After World War I, diver-training programs were cut and the school was not reinstituted.

Navy Diving Manual was published, and the Navy Diving School at Newport, Rhode Island, was established. As a direct result of the program, the first U.S. Throughout the three-year program, divers went progressively deeper, eventually reaching 274 fsw. 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. Navy divers rarely went below 60 fsw (feet of seawater), and that was a real problem for submarine rescue operations.
submarine force also came with it an increase in accidents, collisions, and sinkings. The beginning of the twentieth century marked the development of a weapon of immense potential-the submarine. David Farragut’s ships to locate and disarm Confederate mines, and in 1898, Navy divers investigated the mysterious explosion of USS Maine while anchored in the harbor of Havana, Cuba. During the Civil War’s Battle of Mobile Bay, swimmers were sent ahead of Adm.
Navy has used divers on the salvage and repair of ships, construction, and other military operations. Since the middle of the nineteenth century, the U.S.
