** The 2022 Nuclear Posture Review: Arms Control Subdued By Military Rivalry

Titled: The 2022 Nuclear Posture Review:
Arms Control Subdued By Military Rivalry
By Hans Kristensen and Matt Korda • October 27, 2022

On 27 October 2022, the Biden administration finally released an unclassified version of its long-delayed Nuclear Posture Review (NPR). The classified NPR was released to Congress in March 2022, but its publication was substantially delayed––likely due to Russia’s invasion of Ukraine.

Compared with previous NPRs, the tone and content come closest to the Obama administration’s NPR from 2010. However, it contains significant adjustments because of the developments in Russia and China. (See also our global overview of nuclear arsenals)

Despite the challenges presented by Russia and China, the NPR correctly resists efforts by defense hawks and nuclear lobbyists to add nuclear weapons to the U.S. arsenal and delay the retirement of older types. Instead, the NPR seeks to respond with adjustments in the existing force posture and increase integration of conventional and nuclear planning.

Although Joe Biden during his presidential election campaign spoke strongly in favor of adopting no-first-use and sole-purpose policies, the NPR explicitly rejects both for now.

From an arms control and risk reduction perspective, the NPR is a disappointment. Previous efforts to reduce nuclear arsenals and the role that nuclear weapons play have been subdued by renewed strategic competition abroad and opposition from defense hawks at home.

Even so, the NPR concludes it may still be possible to reduce the role that nuclear weapons play in scenarios where nuclear use may not be credible.

Unlike previous NPRs, the 2022 version is embedded into the National Defense Strategy document alongside the Missile Defense Review.

Below is our summary and analysis of the major portions of the NPR:

The Nuclear Adversaries

The NPR identifies four potential adversaries for U.S. nuclear weapons planning: Russia, China, North Korea, and Iran. Of these, Russia and China are obviously the focus because of Russia’s large arsenal and aggressive behavior and because of China’s rapidly increasing arsenal. The NPR projects that “[b]y the 2030s the United States will, for the first time in its history, face two major nuclear powers as strategic competitors and potential adversaries.” This echoes previous statements from high-ranking US military leaders, including the former and incoming Commanders of US Strategic Command although the NPR appears less “the sky is falling.”

China: Given that the National Defense Strategy is largely focused on China, it is unsurprising that the NPR declares China to be “the overall pacing challenge for U.S. defense planning and a growing factor in evaluating our nuclear deterrent.”

Echoing the findings of the previous year’s China Military Power Report, the NPR suggests that “[t]he PRC likely intends to possess at least 1,000 deliverable warheads by the end of the decade.” According to the NPR, China’s more diverse nuclear arsenal “could provide the PRC with new options before and during a crisis or conflict to leverage nuclear weapons for coercive purposes, including military provocations against U.S. Allies and partners in the region.”

See also our Nuclear Notebook on Chinese nuclear forces.

Russia: The NPR presents harsh language about Russia, in particular surrounding its behavior around the invasion of Ukraine. In contrast to the Trump administration’s NPR, the assumptions surrounding a potential low-yield “escalate-to-deescalate” policy have been toned down; instead the NPR simply states that Russia is diversifying its arsenal and that it views its nuclear weapons as “a shield behind which to wage unjustified aggression against [its] neighbors.”

The review’s estimate of Russian non-strategic nuclear weapons –– “up to 2,000 –– matches those of previous military statements. In 2021, the Defense Intelligence Agency concluded that Russia “probably possesses 1,000 to 2,000 nonstrategic nuclear warheads.” The State Department said in April 2022 that the estimate includes retired weapons awaiting dismantlement. The subtle language differences reflect a variance in estimates between the different US military departments and agencies.

The NPR also suggests that “Russia is pursuing several novel nuclear-capable systems designed to hold the U.S. homeland or Allies and partners at risk, some of which are also not accountable under New START.” Given that both sides appear to agree that Russia’s new Sarmat ICBM and Avangard hypersonic glide vehicle fit smoothly into the treaty, this statement is likely referring to Russia’s development of its Burevestnik nuclear-powered cruise missile, its Kinzhal air-launched ballistic missile, and its Status-6 Poseidon nuclear torpedo.

It appears that Russia and the United States are at odds over whether these three systems are treaty-accountable weapons. In 2019, then-Under Secretary Andrea Thompson noted during congressional testimony that all three “meet the US criteria for what constitutes a “new kind of strategic offensive arms’ for purposes of New START.” However, Russian officials had previously sent a notice to the United States stating that they “find it inappropriate to characterize new weapons being developed by Russia that do not use ballistic trajectories of flight moving to a target as ‘potential new kinds of Russian strategic offensive arms.’ The arms presented by the President of the Russian Federation on March 1, 2018, have nothing to do with the strategic offensive arms categories covered by the Treaty.”

See also our Nuclear Notebook on Russian nuclear forces.

North Korea: In recent years, North Korea has been overshadowed by China and Russia in the U.S. defense debate. Nonetheless this NPR describes North Korea as a target for U.S. nuclear weapons planning. The NPR bluntly states: “Any nuclear attack by North Korea against the United States or its Allies and partners is unacceptable and will result in the end of that regime. There is no scenario in which the Kim regime could employ nuclear weapons and survive.”

See also our Nuclear Notebook on North Korean nuclear forces.

Iran: The NPR also describes Iran even though it does not have nuclear weapons. Interestingly, although Iran is not in compliance with its NPT obligations and therefore does not qualify for the U.S. negative security assurances, the NPR declares that the United States “relies on non-nuclear overmatch to deter regional aggression by Iran as long as Iran does not possess nuclear weapons.”

Nuclear Declaratory Policy

The NPR reaffirms long-standing U.S. policy about the role of nuclear weapons but with slightly modified language. The role is: 1) Deter strategic attacks, 2) Assure allies and partners, and 3) Achieve U.S. objectives if deterrence fails.

The NPR reiterates the language from the 2010 NPR that the “fundamental role” of U.S. nuclear weapons “is to deter nuclear attacks” and only in “extreme circumstances.” The strategy seeks to “maintain a very high bar for nuclear employment” and, if employment of nuclear weapons is necessary, “seek to end conflict at the lowest level of damage possible on the best achievable terms for the United States and its Allies and partners.”

Deterring “strategic” attacks is a different formulation than the “deterrence of nuclear and non-nuclear attack” language in the 2018 NPR, but the new NPR makes it clear that “strategic” also accounts for existing and emerging non-nuclear attacks: “nuclear weapons are required to deter not only nuclear attack, but also a narrow range of other high consequence, strategic-level attacks.”

Indeed, the NPR makes clear that U.S. nuclear weapons can be used against the full spectrum of threats: “While the United States maintains a very high bar for the employment of nuclear weapons, our nuclear posture is intended to complicate an adversary’s entire decision calculus, including whether to instigate a crisis, initiate armed conflict, conduct strategic attacks using non-nuclear capabilities, or escalate to the use of nuclear weapons on any scale.”

During his presidential campaign, Joe Biden spoke repeatedly in favor of a no-first-use and sole-purpose policy for U.S. nuclear weapons. But the NPR explicitly rejects both under current conditions. The public version of the NPR doesn’t explain why a no-first-use policy against nuclear attack is not possible, but it appears to trim somewhat the 2018 NPR language about an enhanced role of nuclear weapons against non-nuclear strategic attacks. And the stated goal is still “moving toward a sole purpose declaration” when possible in consultation with Allies and partners.

In that context the NPR reiterates previous “negative security assurances” that the United States “will not use or threaten to use nuclear weapons against non-nuclear weapon states that are party to the NPT [Nuclear Non-Proliferation Treaty] and in compliance with their nuclear non-proliferation obligations.”

“For all other states” the NPR warns, “there remains a narrow range of contingencies in which U.S. nuclear weapons may still play a role in deterring attacks that have strategic effect against the United States or its Allies and partners.” That potentially includes Iran, North Korea, and Pakistan.

Interestingly, the NPR states that “hedging against an uncertain future” is no longer a stated (formal) role of nuclear weapons. Hedging has been part of a strategy to be able to react to changes in the threat environment, for example by deploying more weapons or modifying capabilities. The change does not mean that the United States is no longer hedging, but that hedging is part of managing the arsenal, rather than acting as a role for nuclear weapons within US military strategy writ large.

The NPR reaffirms, consistent with the 2013 Nuclear Employment Strategy, that U.S. use of nuclear weapons must comply with the Law of Armed Conflict (LOAC) and that it is U.S. policy “not to purposely threaten civilian populations or objects, and the United States will not intentionally target civilian populations or objects in violation of LOAC.” That means that U.S. nuclear forces cannot attack cities per se (unless they contain military targets).

Nuclear Force Structure

The NPR reaffirms a commitment to the modernization of its nuclear forces, nuclear command and control and communication systems (NC3), and production and support infrastructure. This is essentially the same nuclear modernization program that has been supported by the previous two administrations.

But there are some differences. The NPR also identifies “current and planned nuclear capabilities that are no longer required to meet our deterrence needs.” This includes retiring the B83-1 megaton gravity bomb and cancelling the nuclear sea-launched cruise missile (SLCM-N). These decisions were expected and survived opposition from defense hawks and nuclear lobbyists.

Although the NPR has decided to move forward with retirement of the B83-1 bomb due to increasing limitations on its capabilities and rising maintenance costs, the NPR appears to hint at a replacement weapon “for improved defeat” of hard and deeply buried targets. The new weapon is not identified.

The NPR concludes that “SLCM-N was no longer necessary given the deterrence contribution of the W76-2, uncertainty regarding whether SLCM-N on its own would provide leverage to negotiate arms control limits on Russia’s NSNW, and the estimated cost of SLCM-N in light of other nuclear modernization programs and defense priorities.” This language is more subtle than the administration’s recent statement rebutting Congress’ attempt to fund the SLCM-N, which states:

“The Administration strongly opposes continued funding for the nuclear sea-launched cruise missile (SLCM-N) and its associated warhead. The President’s Nuclear PostureReview concluded that the SLCM-N, which would not be delivered before the 2030s, is unnecessary and potentially detrimental to other priorities. […] Further investment in developing SLCM-N would divert resources and focus from higher modernization priorities for the U.S. nuclear enterprise and infrastructure, which is already stretched to capacity after decades of deferred investments. It would also impose operational challenges on the Navy.

In justifying the cancelation of the SLCM-N, the NPR spells out the existing and future capabilities that adequately enable regional deterrence of Russia and China. This includes the W76-2 (the low-yield warhead for the Trident II D5 submarine-launched ballistic missile proposed and deployed under the Trump administration), globally-deployed strategic bombers, air-launched cruise missiles, and dual-capable fighter aircraft such as as the F-35A equipped with the new B61-12 nuclear bomb.

The NPR concludes that the W76-2 “currently provides an important means to deter limited nuclear use.” However, the review leaves the door open for its possible removal from the force structure in the future: “Its deterrence value will be re-evaluated as the F-35A and LRSO are fielded, and in light of the security environment and plausible deterrence scenarios we could face in the future.”

The review also notes that “[t]he United States will work with Allies concerned to ensure that the transition to modern DCA [dual-capable aircraft] and the B61-12 bomb is executed efficiently and with minimal disruption to readiness.” The release of the NPR coincides with the surprise revelation that the United States has sped up the deployment of the B61-12 in Europe. Previously scheduled for spring 2023, the first B61-12 gravity bombs will now be delivered in December 2022, likely due to Russia’s invasion of Ukraine and Putin’s nuclear belligerency. Given that the Biden administration has previously taken care to emphasize that its modernization program and nuclear exercises are scheduled years in advance and are not responses to Russia’s actions, it is odd that the administration would choose to rush the new bombs into Europe at this time.

The NPR appears to link the non-strategic nuclear posture in Europe more explicitly to recent Russian aggression. “Since Russia’s invasion of Ukraine and the occupation of Crimea in 2014, NATO has taken steps to ensure a modern, ready, and credible NATO nuclear deterrent.” While that is true, some of those steps were already underway before 2014 and would have happened even if Russia had not invaded Ukraine. This includes extensive modernizations at the bases and of the weapons and adding the United Kingdom to the nuclear storage upgrades. But the NPR also states that “Further steps are needed to fully adapt these forces to current and emerging security conditions,” including to “enhance the readiness, survivability and effectiveness of the DCA mission across the conflict spectrum, including through enhanced exercises…”

In the Pacific region, the NPR continues and enhances extended deterrence with U.S. capabilities and deepened consultation with Allies and partners. The role of Australia appears to be increasing. An overall goal is to “better synchronize the nuclear and non-nuclear elements of deterrence” and to “leverage Ally and partner non-nuclear capabilities that can support the nuclear nuclear deterrence mission.” The last part sounds similar to the so-called SNOWCAT mission in NATO where Allies support the nuclear strike mission with non-nuclear capabilities.

Nuclear-Conventional Integration

Although the integration of nuclear and conventional capabilities into strategic deterrence planning has been underway for years, the NPR seeks to deepen it further. It “underscores the linkage between the conventional and nuclear elements of collective deterrence and defense” and adopts “an integrated deterrence approach that works to leverage nuclear and non-nuclear capabilities to tailor deterrence under specific circumstances.”

This is not only intended to make deterrence more flexible and less nuclear focused when possible, but it also continues the strategy outlined in the 2010 NPR and 2013 Nuclear Employment Guidance to reduce reliance on nuclear weapons by relying more on new conventional capabilities.

According to the NPR, “Non-nuclear capabilities may be able to complement nuclear forces in strategic deterrence plans and operations in ways that are suited to their attributes and consistent with policy on how they are employed.” Although further integration will take time, the NPR describes “how the Joint Force can combine nuclear and non-nuclear capabilities in complementary ways that leverage the unique attributes of a multi-domain set of forces to enable a range of deterrence options backstopped by a credible nuclear deterrent.” An important part of this integration is to “better synchronize nuclear and non-nuclear planning, exercises, and operations.”

Beyond force structure issues, this effort also appears to be a way to “raise the nuclear threshold” by reducing reliance on nuclear weapons but still endure in regional scenarios where an adversary escalates to limited nuclear use. In contrast, the 2018 NPR sought low-yield non-strategic “nuclear supplements” for such a scenario, and specifically named a Russian so-called “escalate-to-deescalate” scenario as a potentially possibility for nuclear use.

Moreover, conventional integration can also serve to reduce reliance on nuclear weapons in response to non-nuclear strategic attacks, and could therefore pave the way for a sole-purpose policy in the future (see also An Integrated Approach to Deterrence Posture by Adam Mount and Pranay Vaddi).

Finally, increasing conventional capabilities in deterrence planning also allows for deeper and better integration of Allies and partners without having to rely on more controversial nuclear arrangements.

A significant challenge of deeper nuclear-conventional integration in strategic deterrence is to ensure that it doesn’t blur the line between nuclear and conventional war and inadvertently increase nuclear signaling during conventional operations.

Arms Control and Non-Proliferation

The NPR correctly concludes that deterrence alone will not reduce nuclear dangers and reaffirms the U.S. commitment to arms control, risk reduction, and nonproliferation. It does so by stating that the United States will pursue “a comprehensive and balanced approach” that places “renewed emphasis on arms control, non-proliferation, and risk reduction to strengthen stability, head off costly arms races, and signal our desire to reduce the salience of nuclear weapons globally.”

The Biden administration’s review contains significantly more positive language on arms control than can be found in the Trump administration’s NPR. The NPR concludes that “mutual, verifiable nuclear arms control offers the most effective, durable and responsible path to achieving a key goal: reducing the role of nuclear weapons in U.S. strategy.”

In that vein, the review states a willingness to “expeditiously negotiate a new arms control framework to replace New START,” as well as an expansive recommitment to the Non-Proliferation Treaty (NPT), the Comprehensive Test-Ban Treaty (CTBT), and the Fissile Material Cutoff Treaty (FMCT). However, the authors take a negative view of the Treaty on the Prohibition of Nuclear Weapons (TPNW), stating that the United States does not “consider the TPNW to be an effective tool to resolve the underlying security conflicts that lead states to retain or seek nuclear weapons.”

Although the NPR states that “major changes” in the role of U.S. nuclear weapons against Russia and China will require verifiable reductions and constraints on their nuclear forces, it also concludes that there “is some opportunity to reduce the role of nuclear weapons in our strategies for [China] and Russia in circumstances where the threat of a nuclear response may not be credible and where suitable non-nuclear options may exist or may be developed.” The NPR does not identify what those scenarios are.

Looking Ahead

Many of the activities described in the NPR are already well underway. Now that the NPR has been completed and published, the Pentagon will produce an NPR implementation plan that identifies specific decisions to be carried out.

Flowing from the reviews that were done in preparation of the NPR, the White House will move forward with an update to the nuclear weapons employment guidance. This guidance will potentially include changes to the strike plans and the assumptions and the assumptions and requirements that underpin them.

The Biden administration must use this opportunity to scrutinize more closely the simulations and analysis that U.S. Strategic Command is using to set nuclear force structure requirements.
