REPORT ON CRITICAL MUNITIONS REQUIRED FOR SIMULTANEOUS CONFLICTS.

SEC. 364. REPORT ON CRITICAL MUNITIONS REQUIRED FOR SIMULTANEOUS CONFLICTS. (a) Report.— (1) In general.—Not later than 180 days after the date of the enactment of this Act, the Secretary of Defense shall submit to the congressional defense committees a report that details the stockpiles of critical munitions required to fight simultaneous conflicts in different theaters of operation. (2) Elements.—The report under paragraph (1) shall include the following elements: (A) An estimate of the number of each critical munition that would be required over the course of simultaneous conflicts in different theaters, modeled on the assumption that a contingency operation in any one of the western Pacific, Europe, Middle East, or Korean Peninsula theaters would increase the likelihood of a contingency operation in one or more other theaters and taking into consideration the prepositioning of stockpiles and the risk posed by moving critical munitions within such stockpiles out of each theater. (B) An estimate of the number of days during such a simultaneous conflict before the current stockpiles of critical munitions of the United States would be exhausted by the United States Armed Forces. (C) An estimate of the time required for the industrial base to replenish critical munition inventories during such a simultaneous conflict, taking into account the Out-Year Unconstrained Total Munitions Requirement under section 222c of title 10, United States Code, and the results of the assessment conducted pursuant to section 1705 of the National Defense Authorization Act for Fiscal Year 2023 (Public Law 117-263; 136 Stat. 2968) but not the assumptions required under the Department of Defense Instruction 3000.04, titled “DoD Munitions Requirements Process”. (D) An identification of the production requirements for each critical munition necessary to address any shortfall between— (i) the production rates as of the date of the report; and (ii) the production rates necessary to meet the number estimated under subparagraph (A). (E) An assessment of the lessons learned from the war in Ukraine with respect to the rates at which munitions are consumed. (F) An assessment of the projected munitions stockpiles of the military forces of the Russian Federation, the People’s Republic of China, Iran, and the Democratic Republic of Korea, and forces affiliated with such military forces. (G) An assessment of the projected stockpiles of munitions of relevant partners and allies of the United States in each theater and opportunities for such partners and allies to enhance contributions to such stockpiles for burden-sharing purposes. (H) An assessment of the projected munitions requirements of such partners and allies in each theater with respect to munitions produced in the United States, including an analysis of how such requirements would affect the elements specified in subparagraphs (A) through (D). (b) Plan.— (1) In general.—Not later than 90 days after the date on which the Secretary of Defense submits the report under subsection (a), the Secretary shall submit to the congressional defense committees a plan to implement critical munitions requirements to fight simultaneous conflicts in the next budget cycle. Such plan shall include a description of such actions by industry, and arsenals and depots owned by the United States, that the Secretary determines would be necessary to meet such requirements. (2) Waiver.—The Secretary may waive the requirement for the submission of a plan under paragraph (1) if the Secretary submits to the congressional defense committees a report with a justification for the decision not to implement the results of the report required by subsection (a)(2)(a) into the requirements process for the next budget cycle. The report shall include an assessment of the gap between current requirements for critical munitions and those requirements identified in the report required by subsection (a)(2)(a). (c) Critical Munitions Defined.—In this section, the term “critical munitions” includes munitions designated on the critical munitions list of the Chairman of the Joint Chiefs of Staff.
