Title 10 › Subtitle Subtitle A— General Military Law › Part V— ACQUISITION › Subpart F— Major Systems, Major Defense Acquisition Programs, and Weapon Systems Development › Chapter 323— LIFE-CYCLE AND SUSTAINMENT › § 4324
The Secretary of Defense must make sure every covered system has a performance-based life-cycle sustainment plan. The plan must be approved by the service acquisition executive and must meet operational and materiel readiness goals under section 118(c) in the most cost-effective way possible. A product support manager must create, update, and carry out the plan. The plan must include a support strategy that covers all Integrated Product Support Elements and lets the team pick the right integrators and providers; a life-cycle cost estimate tied to that strategy (and for major programs, one that supports Milestone A, B, or C approvals); engineering and design choices to lower sustainment costs; an intellectual property plan under section 3774 (covering technical data, software, and modular open systems under section 4401); use of public and private capabilities; and a transition-to-fielding plan that lists tooling, initial spares, manuals, training, facilities, funding needs, and training simulators. While making the plan, the manager must consider affordability, sustainment risks (including contested logistics per section 2926), follow core logistics and depot maintenance rules (sections 2464 and 2466), use commercial best practices and new technologies, and help keep a strong defense industrial base. Definitions (one line each): Milestone decision authority and Milestone approvals — as defined in sections 4251 and 4172; covered system — a major defense acquisition program, a major subprogram, or a rapid fielding/prototyping program expected to reach the cost in section 4201(a)(2); critical readiness items of supply — parts or systems that cause mission impairment or are so designated by the Secretary of Defense; Integrated Product Support Elements — product support management; design interface; sustaining engineering; maintenance planning and management; supply support; support equipment; technical data; training and training support; IT systems continuous support; facilities and infrastructure; packaging/handling/storage/transportation; and manpower and personnel; product support — the set of functions needed to field and sustain systems; product support arrangement — a contract or agreement for sustainment (including performance-based logistics, sustainment support, contractor logistics support, or life-cycle product support); product support integrator — the entity that coordinates public and private support; product support provider — the entity that performs support.
