The report provides the Chief of Naval Operations, Bureau of Naval Personnel, Special Projects Office, Fleet Commanders, and Naval schools with preliminary information related to the diver personnel and training requirements for the Man-in-the-Sea Program, and was prepared at the request of Pers-A41(Personnel Program Management Division). The research memorandum discusses projected diver requirements in the Navy and includes a review of existing and anticipated skills and knowledges, depth qualifications, equipment knowledge required, personnel selection pre-requisites, hazardous duty implications, NEC and diving pay considerations, types of underwater tasks performed, and new technical skills required. Comparison of existing, versus projected diver personnel and training requirements are discussed and reviewed in light of requirements envisioned for an on-going man-in-the-sea effort within the Navy.
