To amend title 10 to shorten breach reporting timelines, increase program transparency, and improve congressional oversight of Department of Defense cost overruns with respect to the cost growth for major systems, and for other purposes.

This bill (HR 4372) requires the Department of Defense to shorten reporting timelines for cost overruns on major defense acquisition programs, cutting the deadline from "when a report is submitted" to 30 days after the report is issued. It adds new rules for designating "end items" costing over $500 million each as separate subprograms for reporting, mandates including full life-cycle operations/support costs in reports, and creates stricter termination rules for programs with repeated cost breaches. Specifically, programs exceeding cost thresholds twice must be terminated within 90 days of reassessment, and all breach reports must be posted publicly on a DoD website. The bill directly affects DoD acquisition programs over $500 million, aiming to improve transparency and congressional oversight of defense spending.
