Which document outlines the procedures and requirements for conducting maintenance?

The correct answer is OPNAVINST 4790.1J, which is the official instruction that specifically outlines the procedures and requirements for conducting maintenance within the Navy. This instruction provides comprehensive guidance for the maintenance and material management processes, covering everything from maintenance planning to the management of maintenance activities. It serves as the primary reference for implementing the 3-M system and establishes the standards and protocols necessary for effective maintenance operations.

In contrast, while the SORM provides valuable insights into the organization and general regulations of the U.S. Navy, it does not specifically focus on the procedures and requirements for conducting maintenance. The Naval Maintenance Directive discusses various maintenance actions but is limited in scope and not as comprehensive as the OPNAVINST 4790.1J. The Maintenance Management Manual provides additional guidance but is secondary to the OPNAV instruction in terms of outlining the overarching maintenance procedures.
