Title 10 › Subtitle A — General Military Law › PART V — ACQUISITION › Subpart F — Major Systems, Major Defense Acquisition Programs, and Weapon Systems Development › CHAPTER 321 — GENERAL MATTERS › § 4203
The Secretary of Defense may break a large defense program into major subprograms when the program needs to deliver two or more types of items that are very different, or when it will deliver separate increments or blocks. The Secretary must tell the congressional defense committees in writing at least 30 days before any such designation starts. If subprograms are designated, official reports must show cost, schedule, and performance data for the whole program and for each subprogram, and unit costs must follow special rules. All parts of the program must be put into one or more subprograms so the entire program is covered. Key terms (one line each): Program acquisition unit cost — total development, procurement, and specific military construction costs allocated to a subprogram divided by the number of fully configured end items to be produced. Procurement unit cost — total procurement funds for a subprogram divided by the number of fully configured end items to be bought. Major contract — the six largest prime, associate, or government‑furnished equipment contracts in the subprogram over $40,000,000 that are not firm‑fixed‑price. Life cycle cost — all costs for development, procurement, military construction, and operations and support for the subprogram.
