§4376 Breach of critical cost growth threshold: reassessment of program; presumption of program termination

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 325— - COST GROWTH—UNIT COST REPORTS (NUNN-MCCURDY) › § 4376

Last updated Apr 6, 2026|Official source

Summary

When the unit cost of a major defense program or a covered subprogram goes up by as much as the critical cost growth threshold, the Secretary of Defense must find the root cause and, with the Director of Cost Assessment and Program Evaluation, do a full reassessment. That reassessment must estimate the cost to finish the program with current requirements, the cost if requirements are reasonably changed, a rough cost of any reasonable alternative, and whether other programs would need less funding because of the cost growth. After that review, the Secretary must end the program unless, within 60 days after the day the required Selected Acquisition Report is due, the Secretary sends Congress a written certification meeting five tests (national security need, no cheaper acceptable alternative, Director’s approval of new cost estimates, priority over programs that would be cut, and adequate management) and a report showing the root-cause analysis and documentation. If the program is terminated, the Secretary must tell Congress why, what alternatives were considered, and how remaining needs will be met.

(1)determine the root cause or causes of the critical cost growth in accordance with applicable statutory requirements and Department of Defense policies, procedures, and guidance; and
(2)in consultation with the Director of Cost Assessment and Program Evaluation, carry out an assessment of—
(A)the projected cost of completing the program if current requirements are not modified;
(B)the projected cost of completing the program based on reasonable modification of such requirements;
(C)the rough order of magnitude of the costs of any reasonable alternative system or capability; and
(D)the need to reduce funding for other programs due to the growth in cost of the program.
(b)(1)After conducting the reassessment required by subsection (a) with respect to a major defense acquisition program, the Secretary shall terminate the program unless the Secretary submits to Congress, before the end of the 60-day period beginning on the day the Selected Acquisition Report containing the information described in section 4375(d) and (e) of this title is required to be submitted under section 4351(f) of this title, a written certification in accordance with paragraph (2).

(A)the continuation of the program is essential to the national security;
(B)there are no alternatives to the program which will provide acceptable capability at less cost;
(C)the new estimates of the program acquisition unit cost or procurement unit cost have been determined by the Director of Cost Assessment and Program Evaluation to be reasonable;
(D)the program is a higher priority than programs whose funding must be reduced to accommodate the growth in cost of the program; and
(E)the management structure for the program is adequate to manage and control program acquisition unit cost or procurement unit cost.
(3)A written certification under paragraph (2) shall be accompanied by a report presenting the root cause analysis and assessment carried out pursuant to subsection (a) and the basis for each determination made in accordance with subparagraphs (A) through (E) of paragraph (2), together with supporting documentation.
(c)If a major defense acquisition program is terminated pursuant to subsection (b), the Secretary shall submit to Congress a written report setting forth—
