Diving Types, Helmets and SCUBA Equipment



The U.S. Navy Deep Sea Diving program consists of several classifications of divers. These are: Second Class Diver, First Class Diver, Saturation Diver, and Master Diver. There are other SPECWAR communities that dive also, such as, Explosive Ordnance Disposal, and UDT/SEAL. Not to forget our "Amphibious Recon Corpsman" aka "Recon DMT".

Navy Diving is comprised of several types of diving such as, Underwater Ship's Husbandry, Underwater Construction, Salvage, Demolition Diving, Saturation, Research, Hyperbaric Medicine, and Diver Training.


MK-5
The MK-5 Diving Helmet and associated Deep Sea Diving equipment are no longer utilized by U.S. Navy Divers for diving. The MK-5 served many arduous years as the Navy's primary diving helmet and is now utilized for decoration and as a symbol of Hard Hat Deep Sea Diving throughout the world. Most of today's Navy Divers have never had the opportunity to dive the MK-5 Diving Helmet. The MK-5 was replaced in the fleet by the MK-12 which was then replaced by the MK-21 as the Navy's Hard Hat for Deep Sea Diving.



MK-21
The MK-21 diving helmet is currently the U.S. Navy's primary diving helmet for salvage and deep water diving. It is also utilized for underwater ship's husbandry on surface ships and submarines. The design was taken from the popular Superlite 17.

The helmet weighs approximately 27 pounds dry and is neutrally buoyant in the water. The shell is made of fiberglass with brass weights. The regulator is similar to a SCUBA second stage and is fitted to an oral nasal mask on the inside of the helmet to prevent CO2 buildup. The helmet is supplied with air through the diving umbilical which also allows for two way communication with the supervisor on the surface.



MK-20
The MK-20 diving rig is utilized in the U.S. Navy primarily for underwater ship's husbandry and enclosed space diving. The MK-20 design derived from the AGA. The MK-20 can be utilized with the diving umbilical for surface supplied diving operations or with SCUBA. If used with SCUBA, the diving mask is attached to the intermediate hose in place of the second stage regulator. The MK-20 is made of rubber and plastic and is extremely lightweight.



EXO BR MS
The Kirby Morgan Dive Systems EXO BR MS Full Face Mask is now certified for use with surface-supplied diving systems in temperatures down to 28°F and to depths of 190 fsw (air), 140 fsw (NITROX), and 300 fsw (HeO 2 ). The EXO features a balanced, fully adjustable demand regulator, an oral nasal mask, and an exo-thermic exhaust system. The EXO is an alternate band mask that can be used in ship husbandry, enclosed space diving, and light salvage work.




Self Contained Underwater Breathing Apparatus

SCUBA consists of the following equipment:

Cylinder (Bottle) - Aluminum, Charged with air to approximately 3000 psig.
Regulator with cylinder pressure gage - Reduces the air pressure and delivers it to the diver.
Mask - Protects the eyes from the water and assists with underwater vision.
Fins - Propulsion.
Buoyancy Compensator/Life Vest - Emergency Floatation and maintains neutral buoyancy.
Knife - To free yourself if you get caught in line underwater, not to attack Great Whites with.
Depth Gage - To ensure that you do NOT exceed the "No Decompression" Limits.
Weight Belt (Optional) - Offsets any positive buoyancy.
Dive Partner - Never dive alone.
Basic understanding of Diving Medicine - Specifically Arterial Gas Embolism and DCS.
An Emergency Plan - Plan to follow in case of a casualty.

Veterans for Constitution Restoration is a non-profit, non-partisan educational and grassroots activist organization. The primary area of concern to all VetsCoR members is that our national and local educational systems fall short in teaching students and all American citizens the history and underlying principles on which our Constitutional republic-based system of self-government was founded. VetsCoR members are also very concerned that the Federal government long ago over-stepped its limited authority as clearly specified in the United States Constitution, as well as the Founding Fathers' supporting letters, essays, and other public documents.

HMS Ark Royal (Aircraft Carrier, 1938-1941) HMS Ark Royal, a 22,000-ton aircraft carrier built at Birkenhead, England, was completed in November 1938. After working-up during the months prior to the September 1939 outbreak of hostilities, she played an important role in the first two years of the Second World War. In December 1939 she was sent to the South Atlantic to help in the search for the German cruiser Admiral Graf Spee. The spring of 1940 saw her participating in the Norwegian campaign, and in July she was one of the ships that attacked the French Navy's base at Mers-el-Kebir, Algeria. The following September, Ark Royal took part in a second assault on the French Navy, this time at Dakar. While covering a Mediterranean convoy in late November, her planes attacked Italian battleships, though without making any hits. In return, she was bombed, and missed, by enemy aircraft.

During March 1941, Ark Royal pursued the German battleships Scharnhorst and Gneisenau during the last phase of their Atlantic sortie. On 26 May of that year, her torpedo planes hit the Bismarck, making the enemy battleship virtually unmaneuverable and allowing other British warships to close and sink her.

Ark Royal was also very active in the Mediterranean during 1941. She struck the port of Genoa in early February, during a bold British Naval raid deep into Italian-controlled waters. On several occasions, she ferried planes to the beleaguered base at Malta and covered Malta-bound convoys. While returning to Gibraltar from one such mission, Ark Royal was torpedoed by the German submarine U-81. After a difficult struggle against progressive flooding, the carrier capsized and sank on 14 November 1941.
