Table 2: Cost of Expended Ground Attack Munitions
Note: The estimates represent the cost of a like-for-like replacement with variants currently being procured. The original acquisition costs likely were incurred many years ago and would be much lower. Tomahawks priced as ground attack version; JASSMs as the -XR variant. Expended ATACMS are assumed to be replaced with PrSMs, as ATACMS is no longer in production.
Source: Authors’ analysis. Estimated expenditures are grounded in DOD-released numbers that was combined with historical employment patterns and the theater order of battle; methodology detailed in Mark F. Cancian and Chris H. Park, “Last Rounds? Status of Key Munitions at Iran War Ceasefire,” CSIS, April 21, 2026 and Mark F. Cancian and Chris H. Park, “Rebuilding U.S. Missile Inventory: A Multiyear Project,” CSIS, May 27, 2026. Unit costs of missiles came from the according DOD budget justification books (Exhibit P-5 and P-40) and Modernized Selected Acquisition Reports.
