A cost DECREASE (~−10% in the FY2025$ figures shown), procurement-driven — GAO’s second-largest decrease; quantity 542 (3 development + 539 procurement). GAO reports these totals only as chart bars, not stated numbers, so the dollar figures here are read off those bars and remain unconfirmed against the SAR — hence still flagged. After GAO’s Jan-2025 cutoff the Army cut the buy to 432 Block II + 69 MH-47G, not yet in this baseline.
