Surface Ship Life Cycle Mandate

To meet mission of the Navy, requiresattainment of 313 ships by 2020.

Attaining 313 requires 240 of todayshulls to remain in service

Maintenance strategy must be alignedin support of:

Individual ship Current Readiness

Fleet Response Plan (FRP) Ao Expected Service Life (ESL)

Life Cycle Plan to support Current Readiness, FRP and ESL 3

Class Maintenance Plans

Class Maintenance Plans (CMP)are the maintenance manual of

the ship class. Specificallyincluded are: Maintenance Delivery Plan including

required dry-docking intervals

Engineered maintenance

requirements such as equipmentoverhauls, shaft replacements, andcorrosion protection

System certification requirements(nuclear, subsafe, flight deck)

CMPs are continuously updatedbased on class maintenancehistory

Class Maintenance Plans (CMP) = Automobiles Maintenance Manual

Summary

Ship maintenance is a complexchallenge that requires overall system

integration. Maintainability requirements developed

from the system requirement and at theindividual equipment level areincorporated into the CMP.

Ship maintenance is tracked at theequipment level and lessons learnedused to improve future readiness.
