Title 10 › Subtitle Subtitle A— - General Military Law › Part PART V— - ACQUISITION › Subpart Subpart F— - Major Systems, Major Defense Acquisition Programs, and Weapon Systems Development › Chapter CHAPTER 321— - GENERAL MATTERS › § 4203
The Secretary of Defense can treat very different parts of a big military buying program as separate "major subprograms" for reporting. That can happen when the parts look and work very differently or when the program will deliver separate increments or blocks. The Secretary must tell the congressional defense committees in writing at least 30 days before making any such designation. Official acquisition reports, unit-cost filings, and program baselines must show cost, schedule, and performance for the whole program and for each designated subprogram. If a subprogram is named, the rest of the program must be organized into one or more other subprograms and treated the same way. Unit costs must be filed using the definitions below. Program acquisition unit cost: at the subprogram level, all development, procurement, and specific military construction costs that can be assigned to the subprogram divided by the number of fully configured end items the subprogram will produce. Procurement unit cost: at the subprogram level, all programmed procurement funds for the subprogram divided by the number of fully configured end items to be bought. Major contract: for a designated subprogram, each of the six largest prime, associate, or government‑furnished equipment contracts under the subprogram that are over $40,000,000 and are not firm‑fixed‑price contracts. Life cycle cost: all costs for development, procurement, military construction, and operations and support for the subprogram, no matter the funding source or who manages it.
