HISTORY OF DESCO DIVING: DESCO was first organized
in 1937 in Wisconsin
under the name Diving Equipment and Salvage Co.Its founders included
a professional deep water diver, a Hollywood producer specializing in underwater photography and a medical doctor who was
a research scientist at Marquette University . This team successfully worked together in developing
a deep water diving suit combined with a helium oxygen breathing mixture which resulted in Desco divers setting two successive
deep water records of 420 and 550 feet.
World War II brought large Navy contracts for diving equipment
to DESCO. They included not only conventional hard-hat gear for
the navy, but also the design, development and manufacture of an oxygen re-breather, known as the "B Lung. By V-J Day, DESCO
was producing more diving equipment than any other company in the world.
In 1946 the company as sold to another group of Milwaukee businessmen and changed its name to Diving
Equipment and Supply Co., Inc. After the Korean War, which again brought an increase in U.S. Navy contracts and orders, the
ownership changed hands several times and has since concentrated on the design and manufacture of commercial and U.S. Navy
Morse was the first company to make the Navy MK V helmet,
starting production in 1916. During the onslaught of World War Two Morse and then Schrader were making dive helmets for the
Navy. Desco and Miller-Dunn went into production around 1942 or 1943. In total only about 7,000 MK V helmets were produced
by all four companies during the war years.
1968, DESCO moved to its present address at 240
North Milwaukee Street in Milwaukee. Today,
continues providing quality diving equipment under the skilled
and creative management of Ric
with the assistance of Bill Pelky.
BRIEF HISTORY of NAVY MK V DEEP SEA DIVING DRESS:
By 1915, the Bureau of Construction and Repair
had designed the MK V Diving Helmet which seemed to address many of the problems encountered in diving. This deep-sea outfit
was designed for extensive, rugged diving work and provided the diver maximum physical protection and some maneuverability.
The 1915 MK V Diving Helmet had an elbow inlet
with a safety valve that allowed air to enter the helmet, but not to escape back up the umbilical if the air supply were interrupted.
Air was expelled from the helmet through an exhaust valve on the right side, below the port. The exhaust valve was vented
toward the rear of the helmet to prevent escaping bubbles from interfering with the diver’s field of vision.

By 1916, several improvements had been made
to the helmet, including a rudimentary communications system via a telephone cable and a regulating valve operated by an interior
push button. The regulating valve allowed some control of the atmospheric pressure. A supplementary relief valve, known as
the spit cock, was added to the left side of the helmet. A safety catch was also incorporated to keep the helmet attached
to the breast plate. The exhaust valve and the communications system were improved by 1927, and the weight of the helmet was
decreased to be more comfortable for the diver.
After 1927, the MK V changed very little.
It remained basically the same helmet used in salvage operations of the USS S-51 and USS S-4 in the mid-1920's. With its associated
deep-sea dress and umbilical, the MK V was used for all submarine rescue and salvage work undertaken in peacetime and practically
all salvage work undertaken during World War II. The MK V Diving Helmet was the standard U.S. Navy diving equipment until
succeeded by the MK 12 Surface-Supplied Diving In February 1980
which in turn was replaced by the MK 21 in December 1993.
