2025—Pub. L. 119–60 amended section generally. Prior to amendment, text related to the objective of the defense acquisition system, the customer of the defense acquisition system, and the role of the customer of a major defense acquisition program.

2021—Pub. L. 116–283 renumbered section 2546a of this title as this section and transferred it so as to appear after section 3101 of this title. Directory language transferring this section “within such section” was executed as if it had read “within such chapter”, meaning chapter 205 of this title, to reflect the probable intent of Congress.

Amendment by Pub. L. 116–283 effective Jan. 1, 2022, with additional provisions for delayed implementation and applicability of existing law, see section 1801(d) of Pub. L. 116–283, set out as a note preceding section 3001 of this title.

L. 111–23, title II, § 201(a), May 22, 2009, 123 Stat. 1719, which related to consideration of trade-offs among cost, schedule, and performance objectives in Department of Defense acquisition programs, was repealed by Pub. L. 119–60, div. A, title XVIII, § 1811(h)(4), Dec. 18, 2025, 139 Stat. 1244.
