Title 10 › Subtitle 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 can treat parts of a big weapon or equipment program as separate major subprograms when those parts are very different in form or function, or when the program uses separate increments or blocks. The Secretary must notify the congressional defense committees in writing at least 30 days before the change. Official acquisition reports, unit-cost reports, and program plans must show cost, schedule, and performance for the whole program and for each designated subprogram. If one piece is named a major subprogram, the rest of the program must be grouped into one or more subprograms and reported the same way. Defined terms (one line each): program acquisition unit cost — total development, procurement, and specified military construction costs that can be fairly assigned to a subprogram divided by the number of fully configured end items for that subprogram; procurement unit cost — total procurement funds for the subprogram divided by the number of fully configured end items to be bought; major contract — for a subprogram, each of the six largest prime, associate, or government‑furnished equipment contracts over $40,000,000 that are not firm‑fixed‑price; life cycle cost — all development, procurement, military construction, and operations and support costs, regardless of funding source or management control.
