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 › § 4204
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.
