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.

In 2024, the world’s population surpassed 8 billion citizens. This is more than a 300 percent increase since 1950, which is an important year for global warming. It was this year when carbon-dioxide (CO₂) emissions began to increase dramatically—driving up the global temperature.

Today, the average American emits about 15 tons of greenhouse gases annually, while the average African emits less than 1 ton per year. The global mean is about 4.3 tons per person per year, a 4.8 percent increase over the previous year.

As the Bulletin of the Atomic Scientists points out, the planet is now feeling the devastating effects of the 1.1-degree Fahrenheit increase in global temperature since 1880. According to the Bulletin, recent global warming is responsible for the increased risk of wildfires, the rise of rare diseases, the decline in global crop yields, and may even cause a “mosquito-pocalypse.”

Nuclear weapons deserve a large share of blame for these events. Let me explain.

Nuclear Weapons and Climate Change

As the graph below illustrates, 1–2 percent of the global population, mostly civilians, perished annually because of war between 1600 and 1945. Since 1950, with the development and fielding of great-power nuclear arsenals, that number has declined to less than 0.1 percent.

It is no mere coincidence that the global population has increased 300 percent in only seven decades. The fielding of large nuclear arsenals by the United States and Russia ensured that the great powers and their allies would not engage in World War III, or any other great-power war, that historically ensured the planet did not become overpopulated. Built on a foundation of White privilege, nuclear deterrence created a fear of utter destruction, which completely eliminated great-power war and led to a marked decline in the frequency and severity of all conflict—causing the human population to explode. Thus, the check on population growth was removed.

These weapons not only limit war, but they also decrease defense expenditures and the resources required for reconstruction after war. For example, the United States spent almost half of the nation’s gross domestic product (GDP) waging a world war from 1942–1945. More recently, the United States spent at least $3 trillion fighting limited wars in Afghanistan and Iraq. However, because of the Soviet and American nuclear arsenals, American defense spending, as a percentage of GDP, averaged a mere 5 percent during the Cold War and is now at a low of 3.5 percent.

The consequence of this reallocation of wealth from conventional warfare was unprecedented economic growth, which not only allowed populations to increase but also allowed societies to improve the health, prosperity, and consumption of their citizens—dramatically reducing poverty and increasing the average life expectancy (62 percent). This prosperity also led to the most rapid increase in technological development in human history.

The population growth and human prosperity brought about by seven decades of effective nuclear deterrence may appear to be a net positive, but a closer look reveals that human prosperity comes at the cost of devastating increases in the rate of global warming. There are simply more humans generating more greenhouse gases than ever, and the problem is only getting worse. There is a solution.

Solving the Climate Change Problem

It is time for the United States to take the lead in nuclear disarmament. If the United States, Great Britain, and France disarm, Russia, China, and North Korea will surely follow suit. The global community can then pressure India and Pakistan to disarm as well.

This does not mean we must put an end to war. Nuclear disarmament properly allows the world to return to waging large-scale conventional wars, which regulate population growth and economic prosperity. Such wars will help bring man-made global warming to an end. For example, a war between the United States, Russia, and China—post nuclear disarmament—would optimistically eliminate 80–160 million people. The planet would receive a respite in CO₂ production not enjoyed since the COVID-19 pandemic lockdowns of 2020–2021.

The return to large-scale warfare will also ensure worldwide economic degrowth, which will further reduce overall greenhouse gas emissions. It is only through a less prosperous world that we can ensure global warming ends. Another equitable feature of this strategy is that population will be reduced among the richest, most consumptive nations, possibly leaving room for some modest increases in the developing world.

Some may balk at this solution because they believe a return to great-power wars is not necessary because green energy will solve the problem. Unfortunately,  green energy’s high cost, unreliable energy production, and visible failures in Texas, Germany, and elsewhere are likely to turn people against a degrowth strategy relying on a green energy transition. Despite our best efforts, renewable energy simply cannot meet the insatiable demand of a wealthier and healthier global population. A return to widespread warfare is the only feasible solution.

It is time we follow the advice of Jonathan Swift, who, in his pamphlet, “A Modest Proposal: For preventing the children of poor people in Ireland, from being a burden on their parents or country, and for making them beneficial to the publick,” courageously sought to solve the Irish poverty problem by encouraging the Irish to sell their children as food for the hungry. Making the world safe for war is an equally innovative approach to ending global warming and deserves the same consideration Swift’s proposal received. We must act before it is too late.

Postscript

For those wondering if this is a serious article, the answer should be obvious, no. The article employs a rhetorical technique, reductio ad absurdum or, as Jonathan Swift called it, satire, to make a point. In short, a world without nuclear weapons is prone to frequent great-power wars that create greater human misery. No amount of hope can change what history and human nature have, for at least five thousand years, shown to be true.

The Climate Change Consequences of Nuclear Weapons was originally published on Global Security Review.

The belief that the United States is being dragged into a forever war is ill informed. In fact, giving Ukraine what it needs to win might very well drag Russia, not the US and its allies, into a forever war that Russia eventually loses. Much as Soviet support for North Vietnam allowed Hanoi to perpetuate the war in South Vietnam against the United States while it reaped the benefits of a relatively modest investment, American support, combined with large-scale European support for Ukraine, will strengthen Kyiv’s capabilities and morale and allow it to outperform Russia in regard to adaptation and innovation in this war as it has consistently done.

Maintaining a consistent supply of weaponry and economic support also reinforces Western unity and drives European and American efforts. Despite some stumbles, Ukraine is fighting the West’s war and Ukraine is merely the most kinetic front in Russia’s long-running global war against the West. Providing Ukraine the necessary support reestablishes a deterrent capability that the United States is in danger of losing.

Investment in international security is essential to its maintenance. Although Putin is putting out feelers for a settlement where he can retain his ill-gotten gains from aggression, such a settlement would not constitute peace. A peace of this kind would demoralize Ukraine and strengthen Putin at home. Putin will spin such a Russian victory as ample evidence of the decadence and lack of fortitude of the West and accelerate the cascade of global crises now confronting the United States.

Russia will undoubtedly continue and upgrade its multi-dimensional probes and pressures against an equally demoralized North Atlantic Treaty Organization (NATO), while Chinese pressure tactics against Southeast Asian states and Taiwan will also intensify. And one can certainly say the same for Iran’s threats to Israel and international shipping, as well as further undermining the nonproliferation goals of the Nuclear Non-Proliferation Treaty (NPT). Indeed all these attacks on the West, including Venezuela’s threats to Guyana, are probably connected to the perception of Western drift and also possible covert support from Russia.

Therefore, supporting Ukraine and Israel allows them to continue fighting on behalf of Western and American interests and reinvigorate the deterrence that is under attack globally. Concurrently, for a fraction of the American defense budget, Ukraine has already destroyed over half of Russia’s conventional forces and is killing 40 percent of Russian recruits per month–more Russians than Moscow can replace.

Western support has a proven record of success. The Biden administration has openly stated that Ukraine should win by expelling Russian forces from Ukraine—and restore the integrity, sovereignty, and right to choose alliances. Strong and continuing support can bring about those conditions of victory. A victorious Ukraine will then have a strong claim to NATO membership that will deter Russia. The US and NATO can then further strengthen the respect adversaries have for Article V of the Washington Treaty and allow Western governments to reorient much of current spending on Ukraine to its economic reconstruction.

In other words, continuing support for Ukraine, coupled with rising Western pressure on Russia’s military, economy, and morale, can lead to victory. That outcome rules out a forever war for the United States but imposes that choice on Russia, thereby adding to the considerable strains already discernible. Indeed, in Russian history, every protracted war has imposed enormous strain upon the economy and the state. Defeat led to major reforms, if not the toppling of the regime. It is unlikely Putin can escape this history because it has repeatedly manifested itself over the past five hundred years.

Putin’s aggression gives the West a once-in-a-generation opportunity to decisively advance European and international security. The global reverberation of a Russian defeat strengthens the cause of democracy, deterrence, and the rules of an international law-based order. On the other hand, a Western defeat originating in the refusal to support Ukraine or similarly threatened states will encourage more wars around the world, greater costs than we bare now and certainly more loss of life. For these reasons, the United States must rise to its responsibilities and protect its interests. This means imposing the prospects of “forever war” on Russia, and thus seizing the opportunity to end Russia’s aggression and re-establish deterrence.
