www.cbo.gov
CBO estimates that plans for U.S. nuclear forces, as described in the fiscal year 2025 budget and supporting documents, would cost $946 billion over the 2025–2034 period, $190 billion more than CBO's 2023 estimate for the 2023–2032 period.

According to a report by the Congressional Budget Office, the cost of operating and modernizing the US nuclear arsenal will increase to $946 billion by 2034, which is a quarter higher than in the same forecast for 2023.

It is separately noted that the forecast does not take into account the cost overruns of 81% for the Sentinel ICBM program, which is being developed to replace the Minuteman III.
