What Will the Administration’s Plans forNuclear Forces Cost Over the Next Decade?
Between 2014 and 2023, the costs of the Administration’s plans for nuclear forces will total $355 billion, in CBO’s estimation. Of that total, $296 billion represents CBO’s projection of the amounts budgeted for strategic and tactical nuclear delivery systems ($136 billion over 10 years); for nuclear weapons, DOE’s nuclear weapons enterprise, and SSBN nuclear reactors ($105 billion over 10 years); and for nuclear command, control, communications, and early-warning systems ($56 billion over 10 years). The remaining $59 billion of the total represents CBO’s estimate of the additional costs that will ensue over the coming decade, beyond the budgeted amounts, if the nuclear programs experience cost growth at the same average rate that similar programs have experienced in the past.
In addition to operating and maintaining current systems, DoD and DOE plan to modernize or replace many weapons and delivery systems over the next few decades. Planned nuclear modernization programs include new SSBNs, long-range bombers, ICBMs, and cruise missiles, as well as major life-extending refurbishments of current ICBMs, submarine-launched ballistic missiles, and nearly all nuclear warheads. Of the $241 billion budgeted for nuclear delivery systems and weapons over the next 10 years (combining the $136 billion and $105 billion figures in the preceding paragraph), CBO estimates that $152 billion would be spent to field and maintain the current generation of systems and $89 billion would be spent to modernize or replace those systems. Because
most of those modernization efforts are just beginning, annual costs for nuclear forces are expected to increase.
From 2021 to 2023, nuclear costs would average about $29 billion annually, roughly 60 percent higher than the $18 billion requested for 2014. Annual costs are likely to continue to grow after 2023 as production begins on replacement systems.
CBO formulated its estimates using a three-step
approach: identify all budget line items relevant to
nuclear forces; extrapolate from budget documentation,
as necessary, to estimate budgets over the 10-year period
(most of DoD’s programs have five-year estimates); and
estimate cost growth beyond budgeted amounts on the
basis of historical growth in similar programs. CBO estimated
cost growth for various types of activities on the
basis of historical average growth for similar activities
because predicting cost growth for individual programs is
particularly complicated. CBO used only the unclassified
portion of DoD’s budget to formulate its estimates.1
The costs of other nuclear-related activities will total
$215 billion from 2014 to 2023, CBO estimates, with
$74 billion in legacy nuclear costs, $34 billion for threat
reduction and arms control, and $107 billion for
defenses.
