The credibility of the nation’s nuclear deterrent, the ultimate guarantor of sovereignty, is inextricably linked to domestic well-being. Economic prosperity, social cohesion, and the trust citizens have in their institutions are all part of that amorphous concept. Adversaries like Russia and China understand that it is in their interest to undermine American societal health; it is time Americans realize the challenge facing the nation.

For decades, the logic of nuclear deterrence rested on a triad of capabilities, credibility, and communication. The United States fielded the world’s most advanced nuclear arsenal and communicated credibility effectively. But credibility—the unwavering belief in America’s will to act—is the lynchpin.

This is where the home front becomes the front line. A nation that is prosperous, unified, and optimistic possesses the strategic endurance to maintain its commitments. Societal well-being is not a “soft” issue separate from “hard” power; it is a foundational strategic asset that fuels long-term political resolve.

The mechanisms connecting a healthy society to a credible deterrent are not merely theoretical. They are etched into recent history. Consider the 1980s under President Reagan. An economic resurgence and a renewed sense of national confidence provided the political capital and financial resources for a sweeping modernization of nuclear forces that saw the Peacekeeper ICBM and the B-2 stealth bomber enter service.

This was not just a military build-up; it was a clear signal to the Soviet Union, born from a nation that had the resources and the will to compete over the long haul. High public trust, buoyed by economic stability, sustained the political commitment for these massive, multi-decade investments.

Contrast this with the period following the 2008 financial crisis. The ensuing economic pain, political polarization, and public discontent led directly to the Budget Control Act and sequestration, which imposed punishing cuts on the defense budget. Allies and adversaries alike watched as Americans debated whether they could afford to modernize an aging nuclear triad. The signal was one of constraint and introspection, raising quiet questions in foreign capitals about the long-term reliability of America’s security guarantees. A nation struggling with internal economic and social crises inevitably projects an image of distraction and dwindling resolve.

Adversaries did not miss this lesson. They astutely integrated America’s domestic vulnerabilities into their national security strategies. China and Russia are engaged in a relentless campaign of information warfare designed to exacerbate our societal fissures. State-controlled media outlets like CGTN (Chinese) and RT (Russian), amplified by armies of bots and trolls on social media, relentlessly spotlight American inequality, racial tensions, and political gridlock.

Their goal is twofold: erode the confidence of Americans in their own democratic system and persuade the world that the United States is a chaotic, declining power whose deterrence is brittle and promises are hollow. By turning societal metrics into weapons against Americans, adversaries aim to achieve strategic gains without firing a shot.

Of course, the relationship between societal health and defense is not without its complexities. A valid counterargument holds that a society enjoying high well-being might become complacent, preferring to spend its “peace dividend” on social programs rather than defense. The post–Cold War era saw this exact debate, as calls to shift funding from “guns to butter” grew louder.

This presents a genuine leadership challenge that requires articulating why investments in national security are essential to protecting the very prosperity and stability Americans enjoy. The choice is not always between a new healthcare program and a new submarine. A strong, healthy, and educated populace, free from economic precarity, is the very foundation that allows a nation to project power and afford the tools of its own defense. A robust social safety net and a powerful military are not mutually exclusive—they are mutually reinforcing pillars of a resilient state.

This calculus extends to the nation’s most critical strategic advantage: America’s network of alliances. The strength of the North Atlantic Treaty Organization (NATO), for instance, is not purely a measure of its combined military hardware. It is rooted in a collective commitment to democratic values and the shared societal well-being of its members.

A stable, prosperous, and unified America reassures allies and strengthens collective deterrence. Conversely, an America seen as internally fractured and unreliable invites doubt, weakening the very alliances that magnify American power. When allied societies are confident in American leadership, collective credibility soars.

Therefore, Americans must rethink national security for the twenty-first century by placing American well-being at the very heart of our strategic imperatives. Bridging the economic divide not only broadens our tax base but also strengthens social cohesion, enabling sustainable defense budgets without overburdening taxpayers. Revitalizing education fuels scientific breakthroughs and cultivates the skilled workforce needed to modernize our nuclear command, control, and delivery systems. Upgrading infrastructure, from critical ports and highways to resilient cybersecurity networks, enhances our logistical agility, accelerates force deployment, and bolsters the credibility of our deterrent. By fostering political unity, we project resolve to allies and adversaries alike, inoculating our society against foreign information warfare and ensuring decisive, coordinated responses in times of crisis.

The defining contest of this century will not be waged on traditional battlefields but in a struggle of systems: our free, prosperous, and cohesive society versus an authoritarian model of centralized control. To secure our peace, we must fortify America’s Silent Shield at home. The credibility of our nuclear deterrent, and, by extension, our global leadership, will always mirror the resilience and unity of the nation it protects.

By incorporating stealth, the KC-Z can operate discreetly in contested airspace, safeguarding both itself and the aircraft it refuels such as the F-22, F-35, B-2, and B-21. Additionally, the enhanced capabilities of the KC-Z significantly extend operational reach, allowing aircraft to operate farther from their bases and demonstrate a rapid response to global threats, thus serving as a powerful deterrent.

Technical specifications and design details for the KC-Z are still under development. However, Lockheed Martin’s proposed design emphasizes stealth as a core feature, incorporating low-observable materials, shaping, and potentially radar-absorbing coatings. The KC-Z is expected to be larger than existing tankers to accommodate a substantial fuel capacity and potentially integrate advanced mission systems, such as enhanced communication and electronic warfare capabilities. The design will likely include features to reduce its infrared and acoustic signatures, further enhancing its stealth capabilities. Details about the refueling mechanism, boom or drogue system, are yet to be finalized, but it is expected to be compatible with various aircraft types, including fighters, bombers, and, potentially, unmanned aerial vehicles.

The KC-Z’s presumed ability to loiter for extended periods enhances the US military’s persistent presence in critical regions, reinforcing extended deterrence commitments to allies and partners. Although the US Congress has halted plans to phase out the current fleet of KC-135s until the USAF can submit a formal acquisition strategy for the KC-Z, the acknowledgement of the KC-Z’s importance as a definitive force multiplier that amplifies air combat capabilities through the enablement of longer flight durations, expanded mission support, and overall greater flexibility, further deterring adversaries, highlights the pivotal role the KC-Z will have by integrating with other advanced platforms by enabling coordinated operations across multiple domains.

While the exact timeline and cost of the KC-Z project remain fluid, current projections estimate the first operational aircraft to be fielded by 2040. The USAF is currently in the initial phases of the acquisition process, with a request for information issued in early 2023. This will be followed by an analysis of alternatives to determine the specific requirements and design of the NGAS, which includes the KC-Z. The development of a stealth aircraft with aerial refueling capabilities is expected to be a complex and costly endeavor, with estimates reaching into the tens of billions of dollars. However, proponents argue that the long-term strategic advantages and enhanced operational capabilities justify the significant investment.

Despite the potential advantages, the development and deployment of the KC-Z faces significant challenges. The high cost associated with developing and maintaining stealth aircraft raises concerns about the project’s overall cost-effectiveness, especially considering the budgetary constraints in the defense budget. Additionally, questions remain about the long-term viability of maintaining the KC-Z’s stealth profile, given the wear and tear of regular operations and potential advancements in radar technology by adversaries. Some argue that investing in alternative refueling solutions, such as unmanned tankers or ground-based refueling systems, might be more practical and cost-efficient. Furthermore, integrating a new, complex platform like the KC-Z into existing air operations could pose logistical and operational challenges, requiring substantial adjustments to training, tactics, and maintenance procedures.

Though the Next-Generation Air-Refueling System (NGAS) includes the KC-Y or “bridge tanker” that will close capability gaps between the future KC-46 and KC-Z, recognizing the importance of stealth design in aerial refueling airframes to the deterrence mission will strengthen the United States deterrence strategy by expanding operational capabilities in contested environments, projecting power globally, maintaining a persistent presence, multiplying force effectiveness, and fostering integrated operations. The KC-Z represents a critical evolution in air refueling, aligning it with the demands of modern warfare.

The development of the KC-Z places the U.S. at the forefront of aerial refueling technology, potentially sparking a new arms race as other nations seek to maintain parity or develop their own stealth tanker capabilities. This could have significant implications for international relations and global security. While the KC-Z is primarily intended for defensive and deterrence purposes, its potential offensive applications could raise concerns among rival nations, further fueling geopolitical tensions. Conversely, the KC-Z could also act as a deterrent by showcasing American technological prowess and bolstering alliances with countries that benefit from extended airpower projection capabilities. The international community will undoubtedly be watching the development and deployment of the KC-Z closely, assessing its potential impact on the global balance of power and the future of aerial warfare.

The introduction of the KC-Z could significantly reshape the USAF’s strategic posture. By enabling stealth aircraft to operate deeper into contested airspace, the KC-Z would expand the reach and effectiveness of airpower, potentially altering the dynamics of air combat and deterrence. This could lead to new operational concepts and tactics, as commanders leverage the KC-Z’s unique capabilities to project power and maintain air superiority in challenging environments.

The ability to conduct extended missions with fewer refueling stops could also streamline logistics and reduce the vulnerability of support aircraft. Furthermore, the KC-Z could play a crucial role in enabling distributed operations, where aircraft disperse across a wider area to minimize the risk of detection and enhance survivability. This shift towards a more agile and resilient force structure could have far-reaching implications for the future of air warfare.

Integrating AI/ML into low-observable technology presents a promising avenue for enhancing stealth capabilities, but it also comes with its own set of challenges. ML algorithms rely on large volumes of high-quality data for training and validation. Acquiring such data for low-observable technology is challenging due to the classified nature of military operations and the limited availability of real-world stealth measurements.

ML algorithms analyze vast amounts of radar data to identify patterns and anomalies that were previously undetectable. This includes the ability to track stealth aircraft and missiles with greater accuracy and speed. These advancements have significant implications for deterrence strategies as traditional stealth technology may diminish in its effectiveness as AI/ML-powered radar becomes more sophisticated, potentially undermining the deterrent value of stealth aircraft and missiles.

Stealth technology remains a cornerstone of deterrence, allowing military assets to operate relatively undetected. Radar, on the other hand, is the primary tool for detecting and tracking these assets. However, AI/ML are propelling both technologies into new frontiers. AI algorithms can now design and optimize stealth configurations that were previously impossible. This includes the development of adaptive camouflage that dynamically responds to changing environments, making detection even more challenging.

Furthermore, stealth technology encompasses a multitude of intricately designed principles and trade-offs, including radar cross-section (RCS) reduction, infrared signature management, and reduction of acoustic variables. Developing ML algorithms capable of comprehensively modeling and optimizing these complex interactions poses a significant challenge. Moreover, translating theoretical stealth concepts into practical design solutions that can be effectively learned by ML models requires specialized domain knowledge and expertise.

As ML-based stealth design techniques become more prevalent, adversaries may employ adversarial ML strategies to exploit vulnerabilities and circumvent the defenses afforded to stealth aircraft. Adversarial attacks involve deliberately perturbing input data to deceive ML models and undermine their performance. Mitigating these threats requires the development of robust countermeasures and adversarial training techniques to enhance the resilience of ML-based stealth systems.

Additional complexities are inherent in the fact that ML algorithms often operate as “black boxes,” making it challenging to interpret their decision-making processes and understand the underlying rationale behind their predictions. In the context of stealth technology, where design decisions have significant operational implications, the lack of interpretability and explainability poses a barrier to trust and acceptance. Ensuring transparency and interpretability in ML-based stealth design methodologies is essential for fostering confidence among stakeholders and facilitating informed decision-making.

Implementing ML algorithms for stealth optimization involves computationally intensive tasks, including data preprocessing, model training, and simulation-based optimization. As low-observable technology evolves to encompass increasingly sophisticated designs and multi-domain considerations, the computational demands of ML-based approaches may escalate exponentially. Balancing computational efficiency with modeling accuracy and scalability is essential for practical deployment in real-world military applications.

Integrating AI and ML into military systems raises complex regulatory and ethical considerations, particularly regarding autonomy, accountability, and compliance with international laws and conventions. Ensuring that ML-based stealth technologies adhere to ethical principles, respect human rights, and comply with legal frameworks governing armed conflict is paramount. Moreover, establishing transparent governance mechanisms and robust oversight frameworks is essential to addressing concerns related to the responsible use of AI in military applications.

Addressing these challenges requires a concerted interdisciplinary effort, bringing together expertise from diverse fields such as aerospace engineering, computer science, data science, and ethics. By overcoming these obstacles, AI/ML has the potential to revolutionize low-observable technology, enhancing the stealth capabilities of military aircraft and ensuring their effectiveness in an increasingly contested operational environment. On the other hand, AI/ML has the potential to significantly impact radar technology, posing challenges to conventional low-observable and stealth aircraft designs in the future.

AI/ML algorithms can enhance radar signal processing capabilities by improving target detection, tracking, and classification in cluttered environments. Analyzing complex radar returns and discerning subtle patterns indicative of stealth aircraft, these algorithms can mitigate the challenges posed by low-observable technology, making it more difficult for stealth aircraft to evade detection.

ML algorithms can optimize radar waveforms in real time based on environmental conditions, target characteristics, and mission objectives. Dynamically adjusting waveform parameters such as frequency, amplitude, and modulation, radar systems can exploit vulnerabilities in stealth designs—increasing the probability of detection. This adaptive approach enhances radar performance against evolving threats, including stealth aircraft with sophisticated countermeasures.

Cognitive radar systems leverage AI/ML techniques to autonomously adapt their operation and behavior in response to changing operational environments. These systems learn from past experiences, anticipate future scenarios, and optimize radar performance adaptively. Continuously evolving their tactics and strategies, cognitive radar systems can outmaneuver stealth aircraft and exploit weaknesses in their low-observable characteristics.

AI/ML facilitates the coordination and synchronization of multi-static and distributed radar networks, comprising diverse sensors deployed across different platforms and locations. By fusing information from multiple radar sources and exploiting the principles of spatial diversity, these networks can enhance target detection and localization capabilities. This collaborative approach enables radar systems to overcome the limitations of individual sensors and effectively detect stealth aircraft operating in contested environments.

ML techniques can be employed to develop countermeasures against stealth technology by identifying vulnerabilities and crafting effective detection strategies. By generating adversarial examples and training radar systems to recognize subtle cues indicative of stealth aircraft, researchers can develop robust detection algorithms capable of outperforming traditional radar techniques. ML provides a proactive defense mechanism against stealth threats, potentially rendering conventional low-observable technology obsolete.

AI and ML enable the construction of data-driven models and simulations that accurately capture the electromagnetic signatures and propagation phenomena associated with stealth aircraft. By leveraging large datasets comprising radar measurements, electromagnetic simulations, and physical modeling, researchers can develop comprehensive models of stealth characteristics and devise innovative counter-detection strategies. These data-driven approaches provide valuable insights into the vulnerabilities of stealth technology and inform the design of more effective radar systems.

In the quest for technological superiority in modern warfare, the integration of AI and ML into radar technology holds significant promise with the potential to challenge conventional low-observable and stealth aircraft designs by enhancing radar-detection capabilities. AI and ML algorithms improve radar signal processing, optimize radar waveforms in real time, and enable radar systems to autonomously adapt their operation. By leveraging multi-static and distributed radar networks and employing adversarial ML techniques, researchers can develop robust detection algorithms capable of outperforming traditional radar systems. Moreover, data-driven modeling and simulation provide insights into the vulnerabilities of stealth technology, informing the design of more effective radar systems.

The rapid advancement of AI/ML is revolutionizing both stealth and radar technologies, with profound implications for deterrence strategies. Traditionally, deterrence has relied on the balance of power and the credible threat of retaliation. However, the integration of AI/ML into these technologies is fundamentally altering the dynamics of detection, evasion, and response, thereby challenging the established tenets of deterrence. Of further concern is the consideration that non-stealth assets become increasingly vulnerable to detection and targeting as ML-powered radar systems become more prevalent. This could lead to a greater reliance on stealth technology, further accelerating the arms race.

This rapid development of AI/ML-powered technologies could destabilize the existing balance of power, leading to heightened tensions and miscalculations. The changing technological landscape may necessitate the development of new deterrence strategies that incorporate AI and ML. This could include a greater emphasis on cyber warfare and the development of counter-AI and counter-ML capabilities.

The integration of AI/ML into stealth and radar technologies will be a game-changer for deterrence. To maintain stability and prevent conflict, policymakers and military strategists must adapt to this new reality of a continuous arms race, wherein both offensive and defensive capabilities are constantly evolving in pursuit of technological superiority. Continued investment in AI/ML research is essential to stay ahead of the curve and maintain a credible deterrent posture. International cooperation on the development and use of AI/ML technologies in military applications is crucial to limit the scope of a potential arms race that regularly shifts the balance of power and destabilizes global security.

The Double-edged Sword of Artificial Intelligence was originally published on Global Security Review.

According to the former commander of Air Force Global Strike Command, General Tim Ray in his testimony to the HASC Strategic subcommittee on 1 May 2019: “The vast majority of targets covered by the bomber leg of the triad require the employment of stand-off weapons.” The LRSO missile will ensure that the bomber force can target high-value threats deep within an advanced integrated air defense system (IADS), reducing risk to aircrew and aircraft.

The LRSO is key to American deterrence credibility. Flexible, survivable, and recallable, America’s bomber force forms the third leg of the strategic nuclear triad. Coupled with the bomber, the LRSO ensures the viability of the air leg which arguably is the most stabilizing force. The LRSO is a valuable tool in maintaining strategic stability because it does not pose a short-notice threat of disarming attack.

However, recognizing and fearing America’s ability to hold at-risk strategic targets deep behind enemy lines regardless of IADS efficacy is a key concern for any autocrat seeking to attack American interests. The LRSO is good news for deterrence.
