Nuclear weapons are now not sufficient to maintain U.S. strategic deterrence. Senior navy leaders and pioneering students imagine a brand new technological revolution is now unfolding, and they’re proper. If we aren’t attentive now, the USA could lose the power to discourage main assaults in coming years.
The previous mannequin of strategic nuclear deterrence is more and more threatened by a brand new suite of navy applied sciences, from hypersonic missiles and superior missile defenses to non-kinetic cyberattacks. Individually, these applied sciences are potent. However collectively, they may revolutionize the best way that nice powers deter and conduct struggle. To keep away from falling behind, the USA should hedge towards disruptive capabilities by modernizing its present nuclear arsenal and enterprise a scientific evaluation of strategic capabilities for the 2030s. This imaginative and prescient for the long run stability of strategic forces ought to then allow protection and diplomatic officers to find out funding priorities accordingly and resolve when and easy methods to have interaction Russia and China to keep away from strategic instability on this new period.
These modern developments are greatest understood via the historic lens of revolutions in navy affairs, or RMAs. Whereas the historical past of warfare is usually evolutionary, sure technological developments—resembling gunpowder, aviation, and precision-guided munitions—have revolutionized warfare and reshaped navy balances and the geopolitical panorama.
Know-how is just not the one variable; RMAs require a convergence of expertise, coaching, doctrine, and operational ideas, in addition to a elementary shift in underlying assumptions, to supply a brand new method of competing and combating. For instance, the UK invented tanks, however Germany revolutionized tank warfare by integrating armor, radio, and airpower with novel ideas for using them. This produced the blitzkrieg of World Struggle II.
The nuclear revolution was maybe essentially the most consequential RMA, since nuclear weapons might do what no different weapon had ever achieved: pose an instantaneous, existential menace. The previous paradigm of strategic deterrence was immediately outdated, as giant armies and navies now not sufficed to discourage main assaults. The appearance and continuous evolution of nuclear weapons finally precipitated a brand new strategy to deterrence in the course of the Chilly Struggle, whereby solely a “triad” of nuclear supply methods—strategic bombers, intercontinental ballistic missiles, and submarine-launched ballistic missiles—was deemed sufficiently diversified to outlive any enemy first strike and retaliate, thereby sustaining stability between nuclear-armed adversaries. These capabilities, which so uniquely have an effect on the very choice to wage struggle, are termed “strategic forces.”
A brand new, second RMA in strategic forces is now underway on the backs of an array of rising applied sciences like hypersonic weapons, superior missile defenses, synthetic intelligence and autonomous methods, high-performance information analytics, quantum computing and sensing, space-based sensors and anti-satellite weapons, and cyberweapons. These threaten to undermine the long-standing nuclear deterrence paradigm and alter the stability of energy among the many United States, Russia, and China. New capabilities can destroy, intercept, or blind conventional supply methods, probably enabling a devastating first strike and precluding adversary retaliation. The nation that first develops a brand new mannequin for utilizing these capabilities in tandem with one another, mastering the rising “strategic forces balance,” could change into the following navy and geopolitical hegemon.
This RMA poses distinct threats to every leg of the present nuclear triad. First, superior Russian and Chinese language air defenses are already difficult the stealth capabilities of U.S. strategic bombers. One in all China’s main protection firms claims to have developed a prototype radar that depends on quantum physics to detect the extremely faint (and usually undiscernible) alerts of stealth plane. With out stealth, U.S. nuclear-armed bombers might function exterior contested airspace and nonetheless attain their targets with standoff cruise missiles, however even these missiles could also be more and more much less more likely to prevail towards extra refined missile defenses.
Second, within the wake of the USA’ profitable kinetic missile protection check final November, ground- and sea-based missile defenses are vastly bettering their skill to shoot down ICBMs and SLBMs, threatening the triad’s ground- and sea-based legs. Whereas it’s nonetheless comparatively simple to overwhelm present missile defenses, new technological developments in directed vitality are very more likely to allow a extra sturdy protection towards massed ballistic missile assaults. In the meantime, capturing down a missile is just not the one option to cease it; in lots of circumstances, it’s preferable to destroy the missile earlier than it ever launches. Right here once more, rising applied sciences quickly will provide an answer: travelling at over 5 occasions the pace of sound, hypersonic missiles supported by artificial aperture radar satellites are more and more able to hitting closely defended or time-critical targets, thereby enabling preemptive “left-of-launch” strikes towards ballistic missile launchers.
Third, and most surprisingly, even the submarine leg of the triad is turning into much less survivable. Technological developments portend swarms of unmanned underwater autos, drawing on better distant sensing capabilities and high-performance information analytics and processing, that may extra successfully, repeatedly, and quickly observe and hunt nuclear-armed submarines. The proliferation of undersea, floating, and space-based sensors will make the oceans much more clear.
When mixed, these applied sciences might allow a devastating first strike for any nation that seizes this first-mover benefit. Think about Russia or China makes use of cyberattacks to blind the U.S. nuclear command, management, and communications structure, hypersonic weapons to preemptively remove ICBM launch websites, underwater drones and superior sensors to hunt submarines, and superior air and missile defenses to “mop up” any retaliatory strikes. It’s questionable whether or not the triad might survive, and thus its deterrent energy can be fatally compromised.
Such a complete first-strike functionality is just not with us but, however present applied sciences foreshadow its looming chance. As mates and foes alike undertake these methods, it’s crucial for the USA to develop a brand new paradigm for understanding and using strategic forces. Solely from a place of technological and doctrinal development vis-à-vis its rivals can the USA negotiate with them to mitigate strategic instability. Heretofore the realm of academia, now’s the time for policymakers to grab the initiative, encourage private and non-private debates like these of the early Chilly Struggle, and realign the nuclear paradigm that also grips the educational and coverage communities.
The US ought to hedge towards this disruptive RMA within the quick time period by sustaining plans for sturdy nuclear modernization of the triad. Thankfully, applied sciences develop at completely different charges; not all legs of the triad might be threatened concurrently over the following decade. If one leg is threatened first, the opposite two legs might present short-term redundancy within the nuclear deterrence mission. Thus, in its upcoming 2022 Nationwide Protection Technique (NDS) and Nuclear Posture Evaluation (NPR), the Biden administration ought to proceed U.S. nuclear modernization insurance policies, whereas resisting pressures to cut back to a “dyad,” to lower the dimensions of the U.S. nuclear arsenal, or to additional delay recapitalization applications.
Nonetheless, modernizing the nuclear triad is just one vital step; creating a brand new assemble for strategic forces is important to sustaining an efficient deterrent into the 2030s. Over the long run, U.S. policymakers want to maneuver past the restricted parameters of the Nuclear Posture Evaluation, which views new applied sciences via the lens of the more and more outdated conventional nuclear paradigm. The strategic forces stability of the long run will embody each nuclear weapons and a set of capabilities comprising the rising non-nuclear applied sciences outlined above. Integrating the NPR throughout the NDS, because the Pentagon introduced it might do earlier within the 12 months, is a optimistic step however is inadequate to develop a brand new strategic forces paradigm.
Subsequently, the Pentagon ought to change the nuclear posture component of its NDS evaluation with a broader Strategic Posture Evaluation or “Strategic Deterrence Evaluation” to discover how strategic forces, each present and rising, can complement one another, threaten what adversaries worth, and thereby realign deterrence for a brand new period. This extra holistic evaluation generally is a foundational pillar in Protection Secretary Lloyd Austin’s “built-in deterrence” idea, by which the U.S. navy would develop “the correct mix of expertise, operational ideas and capabilities – all woven collectively and networked in a method that’s so credible, versatile and so formidable that it’s going to give any adversary pause.”
Questions this new evaluation ought to reply embody: which capabilities, and in what portions, can be most survivable and credible towards enemy counterforce weapons; which targets they need to prioritize to have the best impact on adversary decision-making in each struggle and peace; and the place and the way they might must be postured, relying partially upon allied and accomplice willingness to host and/or function them. And maybe most significantly, with cautious steering by the senior management of the Pentagon, this evaluation ought to decide what strategic deterrence technique, coverage, and posture constructs accounting for these new capabilities might serve to each shield American and allies’ nationwide safety whereas additionally initiating a brand new type of strategic stability with Russia and China.
The solutions to those questions ought to inform funding and modernization priorities over the following decade and past, whereas offering the inspiration for dialogue with China and Russia to keep away from instability in a brand new period of strategic forces. That, nevertheless, is a subject for an additional day, and would be the topic of additional evaluation by these authors.
It’s not too late for the USA to guide the following RMA in strategic forces, simply because it capably led the final. However the time for motion is now.
