Which instruction number governs 3M and to whom does it apply?

• A. 4790.8B
• B. NAVSEA 08
• C. OPNAV 4790.4
• D. 4790.8A

Answer: (A)

3M is the Navy’s Maintenance Management System, and its rules are set by a specific instruction in the 4790 series. The version that directly governs how 3M is implemented and who must follow it is 4790.8B. This instruction details the scope and applicability of the 3M program, meaning it applies to all afloat and shore activities under Navy control that perform maintenance within the 3M framework. The reason this is the best answer is that it is the official document that specifies 3M governance and who it covers. Other documents listed are not the 3M governance instruction: NAVSEA 08 is not the 3M instruction, OPNAV 4790.4 covers broader maintenance and material management topics, and 4790.8A is an earlier revision that has been superseded by the B version.
