The United States' current nuclear force modernisation plans would cost a total of USD400 billion from fiscal year 2017 (FY 2017) through FY 2026, according to a new Congressional Budget Office (CBO) estimate.
The 10-year projection, published on 14 February, is 15% higher than the CBO's previous 2015 estimate of USD348 billion over the FY 2015-24 period.
These costs - meaning the amount needed to be appropriated - were calculated from the Department of Defense's (DOD's) and the Department of Energy's (DOE's) FY 2017 budget requests.
It averages to be USD40 billion annually and accounts for about 6% of the total 10-year national defence costs identified in FY 2017 budget requests.
