Life-Cycle Sustainment Plan (LCSP)

The Life-Cycle Sustainment Plan (LCSP) is required by DoD Instruction 5000.02 “Enclosure 6” and documents the Program Manager‘s (PM) and Product Support Manager’s (PSM) plan for formulating, implementing, and executing the sustainment strategy. The plan is included in the overall Acquisition Strategy of a program and describing the approach and resources necessary to develop and integrate sustainment requirements into the system‘s design, development, Testing & Evaluation, fielding, and operations. It also details the development of a product support package (including any support contracts) and how they contribute to the Warfighter‘s mission requirements by achieving and maintaining the Sustainment Key Performance Parameters (KPP) and Key System Attributes (KSA). [1]

The Life-Cycle Sustainment Plan (LCSP) serves a valuable purpose as a tool in coordinating the efforts, resources, and investment of the DoD Materiel Commands such that downtime for fielded weapons systems is managed through deliberate productivity improvement steps that continually lower the cost of readiness. [3]

Life-Cycle Sustainment Plan (LCSP) Content

The LCSP should address the following areas: [1]

  • The maintenance and support concepts
  • How the sustainment metrics will be achieved and sustained throughout the life-cycle
  • How sustainment is addressed as an integral part of the program‘s acquisition strategy and system design process
  • The assigned responsibilities and management approach for achieving effective and timely acquisition, product support, and availability throughout the life-cycle including the PM role in planning for and executing sustainment
  • The funding required and budgeted by year and appropriation for the main sustainment cost categories including operating & support costs
  • The plan for identifying and selecting sources of repair or support
  • The sustainment risk areas and mitigation plans
  • Product support implementation status
  • Results and recommendations from DoD Component Independent Logistics Assessments (ILA)

Life-Cycle Sustainment Plan (LCSP) Regulations

REGULATORY:  A draft is due for Development RFP Release and approved at Milestone B. The LCSP is reviewed by the Component Agency Executive (CAE) at least every 5 years after a system’s Initial Operational Capability (IOC). [2]

Life-Cycle Sustainment Plan (LCSP) Updates in the Acquisition Process

The LCSP is updated at each milestone and specified decision points to reflect the increased maturity of the product support strategy, any changes in the corresponding product support package, current risks, and any cost reduction activities. The evolution of the LCSP is detailed below: [2]

  • Pre-Milestone A: The LCSP begins in the Materiel Solution Analysis (MSA) Phase by describing the notional product support and maintenance concepts used to determine the sustainment requirements optimizing readiness outcomes and minimal Life Cycle-Cost (LCC).
  • Milestone A: The LCSP will focus on the development of sustainment metrics to influence the design and the product support strategy, and on actions that can be taken prior to Milestone B to reduce future operating and support costs, including software sustainment. Planning will use factors and assumptions consistent with those used in the analysis of alternatives and affordability analysis or justify any deviation from those factors and assumptions.
  • Development Request for Proposals Release Decision Point and Milestone B: The LCSP will focus on finalizing the sustainment metrics, integrating sustainment considerations with design and risk management activities, and refining the execution plan for the design, acquisition, fielding, and competition of sustainment activities.
  • Milestone C: if applicable, the LCSP will focus on ensuring operational supportability and verifying performance.
  • Full-Rate Production Decision or Full Deployment Decision: The LCSP will focus on how sustainment performance is measured, managed, assessed, and reported; and the actions to adjust the product support package to ensure continued competition and cost control while meeting warfighter mission requirements.
  • After Initial Operational Capability (IOC): The LCSP is the principal document governing the system’s sustainment. Programs will update the plan whenever there are changes to the product support strategy, or every 5 years, whichever occurs first, supported by appropriate analyses, sustainment metrics, sustainment costs, system components or configuration (hardware and software), environmental requirements, and disposal plans or costs.

Life-Cycle Sustainment Plan (LCSP) Responsibility

The Program Manager (PM) and Product Support Manager’s (PSM) are responsible for the content and preparation of the LCSP but should work with the user, the Product Support Manager, Product Support Integrator(s), and Product Support Providers to document performance and sustainment requirements specifying objective outcomes, resource commitments, and stakeholder responsibilities. [1]


  • Currently the DoD Components use different names to address this requirement, e.g., the Army’s Supportability Strategy, the USAF’s Life-Cycle Management Plan.
