This legislation significantly amends title 10 to enhance transparency and accountability in Department of Defense major acquisition programs. It shortens the timeline for reporting Nunn-McCurdy breaches to Congress to 30 days and requires the Secretary of Defense to designate individual end items exceeding $500 million in estimated life-cycle costs as major subprograms for separate acquisition reporting. Furthermore, the bill mandates the inclusion of life-cycle operations and support costs in all acquisition reports and requires that critical cost growth reports be made publicly available on a DoD website. To address persistent cost overruns, the bill prohibits the Secretary from certifying a major defense acquisition program that has experienced more than one critical cost breach . Such programs must be terminated within 90 days of the second critical breach reassessment, and the Secretary cannot delegate this certification authority. The legislation also outlines various termination strategies designed to maximize value to the government, including immediate termination or completion of items already in production with obligated funds.
