A genuine cost DECREASE, stated in the SARs: the Feb 2018 baseline $16.2B (BY2017) rose to $17.4B by Dec 2018, then fell steadily to $14.6B in the Dec 2023 MSAR (−10%, quantity unchanged at 542 = 3 development + 539 procurement, incl. common production costs of 69 MH-47G) — procurement-driven, GAO’s second-largest decrease. After GAO’s Jan-2025 cutoff the Army cut the buy to 432 Block II + 69 MH-47G and moved the program to the MTA pathway (Sept 2025); no stated cost pair exists for that structure yet, so this row keeps the 542-aircraft basis.

GAO-25-107569 p.91’s chart bars are these figures converted to FY2025$.
