UNDERSEA TECHNOLOGY 



73 



The Sealab experiments, with related studies and development efforts, 

 have the purpose of providing the Navy with the technology and equip- 

 ment to enable aquanauts to perform military and other national interest 

 missions. However, the saturation diving technique is not considered the 

 most effective method of working underwater for all missions, but rather 

 for those of extended duration. This capability for extended ocean- 

 bottom operations will enable Navy aquanauts to perform underwater sal- 

 vage, construction, search, survey, maintenance, and research tasks here- 

 tofore considered impossible for divers. 



The demand or open-circuit scuba is a militarized version of the 

 commercial model. The unit is nonmagnetic, rugged, and capable of 

 supporting hard-working swimmers to a depth of 130 ft.
