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.
