scope:

a. The ship's 3M system applies to all ships, service craft, small boats, selected shore station equipment, and nonaviation fleet test and support equipment, with the exceptions as noted in subparagraph 4c.

b. Common support equipment used by both ship's force and naval aviation units shall have planned maintenance system (PMS) support provided under reference (b). Scheduling of this maintenance by naval aviation units may be done under the Naval Aviation Maintenance Program to avoid duplicative and redundant schedules.

c. The ship's 3M system does not apply to nuclear propulsion plants and associated test equipment under the cognizance of Naval Sea Systems Command (NAVSEASYSCOM) Nuclear Propulsion (NAVSEA 08), fleet ballistic missile systems, or aeronautical support equipment covered in the Naval Aviation Maintenance Program. Also excluded are civilian operated and maintained ships, small boats, and service craft, unless specifically included as a requirement in a base operating contract or other similar document.

d. All reference (a) activities providing maintenance to ships and other applicable activities shall report their efforts in the maintenance data system (MDS) as described in references (a) and (b).

e. Shore activity level of participation in the ship's 3M system shall be at the request of the shore activity's senior command and should be provided on a cost reimbursable basis. Equipment used ashore which is functionally identical to shipboard installed equipment with ship's 3M support shall be maintained using existing 3M coverage.

Purpose

a. To establish policy and assign responsibilities for the ship's maintenance and material management (3M) system, per references (a) and (b).

b. This instruction has been revised to address changes in responsibilities based on Office of the Chief of Naval Operations (OPNAV) reorganization. This instruction is a complete revision and should be reviewed in its entirety
