In response, CBO published Projected Costs of U.S. Nuclear Forces, 2014 to 2023. The National Defense Authorization Act of 2015 (P.L. 113-291) requires CBO to periodically update its estimate of the cost of nuclear forces. This report constitutes the first such update. CBO estimates that over the 2015â2024 period, the Administrationâs plans for nuclear forces would cost $348 billion, an average of about $35 billion a year, and an amount that is close to CBOâs December 2013 estimate of $355 billion for the 2014â2023 period.
