Summary

For any major defense acquisition program that reaches Milestone A after October 1, 2016, the service acquisition executive of the military department running the program must be the milestone decision authority unless the Secretary of Defense chooses someone else. The Secretary can pick a different official if the program meets certain conditions, such as serving a joint need, being better run by a Defense Agency, having a unit cost increase above the significant or critical thresholds in sections 4371–4375, being critical to an interagency or major technology effort or having major international partners, or if the Secretary believes an alternate official will better achieve cost, schedule, and performance goals. If an alternate is named, the military department can ask to have authority returned to its service acquisition executive, and the Secretary must decide within 180 days. If the Secretary denies the request, they must report the reasons to the congressional defense committees; once a program has exceeded the cost thresholds in sections 4371–4375, reversion is barred except in rare cases. Each Selected Acquisition Report under section 4351 must include certifications by the military department secretary and the service chief that requirements are stable and funding is adequate, and must note any increased risks. The Secretary of Defense must review oversight and keep outside paperwork to a minimum when the service acquisition executive is the decision maker, and must make sure outside oversight does not needlessly raise costs or delay schedules.

(a)The milestone decision authority for a major defense acquisition program reaching Milestone A after October 1, 2016, shall be the service acquisition executive of the military department that is managing the program, unless the Secretary of Defense designates, under subsection (b), another official to serve as the milestone decision authority.
(b)The Secretary of Defense may designate an alternate milestone decision authority for a program with respect to which any of the following applies:
(1)Subject to subsection (f), the Secretary determines that the program is addressing a joint requirement.
(2)The Secretary determines that the program is best managed by a Defense Agency.
(3)The program has incurred a unit cost increase greater than the significant cost threshold or critical cost threshold under sections 4371 through 4375 of this title.
(4)The program is critical to a major interagency requirement or technology development effort, or has significant international partner involvement.
(5)The Secretary determines that an alternate official serving as the milestone decision authority will best provide for the program to achieve desired cost, schedule, and performance outcomes.
(c)(1)After designating an alternate milestone decision authority under subsection (b) for a program, the Secretary of Defense may revert the position of milestone decision authority for the program back to the service acquisition executive upon request of the Secretary of the military department concerned. A decision on the request shall be made within 180 days after receipt of the request from the Secretary of the military department concerned.
(2)If the Secretary of Defense denies the request for reversion of the milestone decision authority back to the service acquisition executive, the Secretary shall report to the congressional defense committees on the basis of the Secretary’s decision that an alternate official serving as milestone decision authority will best provide for the program to achieve desired cost, schedule, and performance outcomes. No such reversion is authorized after a program has incurred a unit cost increase greater than the significant cost threshold or critical cost threshold under sections 4371 through 4375 of this title, except in exceptional circumstances.
(d)For each major defense acquisition program, the Secretary of the military department concerned and the Chief of the armed force concerned shall, in each Selected Acquisition Report required under section 4351 of this title—
(1)certify that program requirements are stable and funding is adequate to meet cost, schedule, and performance objectives for the program; and
(2)identify and report to the congressional defense committees on any increased risk to the program since the last report.
(e)The Secretary of Defense shall review the acquisition oversight process for major defense acquisition programs and shall—
(1)limit outside requirements for documentation to an absolute minimum on those programs where the service acquisition executive of the military department that is managing the program is the milestone decision authority; and
(2)ensure that any policies, procedures, and activities related to oversight efforts conducted outside of the military departments with regard to major defense acquisition programs shall be implemented in a manner that does not unnecessarily increase program costs or impede program schedules.
