US estimates $400bn nuclear forces modernization costs up to 2026

The Congressional Budget Office (CBO) estimated that modernizing US nuclear forces would cost $400bn during the period between 2017 and 2026.


The estimated costs will involve the modernization or replacement of nuclear ballistic missile submarines (SSBNs), land-based intercontinental ballistic missiles (ICBMs), long-range bomber aircraft, shorter-range tactical aircraft, and the nuclear weapons that those delivery systems carry.

The modernization of the nuclear arsenal is anticipated to cost $40bn per year over the next ten years.

The current 10-year estimate is 15% higher than CBO’s most recent previous estimate of the 10-year costs of military nuclear modernization, which projected $348bn over the period from 2015 to 2024.

The modernization would extend the service life of the US’s existing nuclear weapons.

The National Defense Authorization Act for Fiscal Year 2013 tasked CBO with estimating the 10-year costs to operate, maintain, and modernize US nuclear forces, and requires CBO to update its estimate of the cost of nuclear forces every two years.
