In February 2022, days after Russian forces crossed into Ukraine, Putin placed his nuclear arsenal on high alert and warned that any nation interfering would face consequences unlike any in its history. The warning to those who might intervene – specifically NATO. Four years on, NATO has provided extensive military and economic support to Ukraine without paying the price Putin had threatened. However, the threat still begs a question the U.S. has never answered. How would Washington protect the homeland, rather than merely avenge a nuclear strike? President Biden warned Moscow of severe consequences for any nuclear use in Ukraine but kept the American response ambiguous. The U.S. may or may not use nuclear weapons against Russia in defense of Ukraine, but a different reaction may occur if the target were a NATO country.  

Because of the distance between the two countries, a Russian strike on the U.S. would likely require long-range ballistic missiles launched from land or submarine. Even though eighty years of deterrence have kept that prospect remote, a single failure such as a misinterpretation or escalatory mobilization of forces could lead to a catastrophic reaction. The U.S. fields layered interceptors, yet the possibility of wide devastation remains. In January 2025, President Trump issued Executive Order 14186 which launched the “Golden Dome” initiative. The order, titled “The Iron Dome for America,” directed the Pentagon to develop a more sophisticated, layered shield against ballistic, hypersonic, and cruise missiles. The concept is analogous in purpose to Israel’s “Iron Dome,” but the planned U.S. architecture is far broader. It calls for space-based sensors, interceptors, and  non-kinetic capabilities. Potential systems could even include directed-energy weapons such as lasers.  

Antimissile defense is not new. In the 1980s, President Reagan initiated the Strategic Defense Initiative, more widely known as Star Wars. The program envisioned, among others, a space-based antimissile system that could provide a comprehensive defense against enemy missiles. That vision never came to fruition. However, technology has evolved, and the U.S. now operates Ground-Based Midcourse Defense, Aegis, THAAD and Patriot which are foundations for Golden Dome. These could build on and be consolidated to add new space-based antimissile capabilities. However, there are problems with this approach. The Government Accounting Office has documented challenges in transitioning DOD directed-energy prototypes, including high-energy lasers, into operational use and the Congressional Budget Office (CBO) assesses that directed-energy weapons, such as lasers, are unlikely to be fielded soon. Another problem is that the Golden Dome’s cost is still unknown. The CBO’s estimate is that a national missile defense architecture broadly consistent with the executive order could cost upwards of $1.2 trillion to develop, deploy, and operate over two decades. Every dollar carries an opportunity cost, reducing the: money that could be used to modernize other systems or reduce the national debt.  

Further, determining the Golden Dome’s effectiveness is problematic due to the difficulty of  intercepting ballistic missiles, and the need is to stop multiple missiles or further influence an adversary’s actions. The CBO found that a national missile defense architecture of this type could fully engage a regional-adversary attack or a small-scale attack by a peer adversary, but it could be overwhelmed by a full-scale attack from Russia or China.  

The CBO also warned that deployment could prompt adversaries to increase missile inventories, expand long-range arsenals, or pursue more effective countermeasures, including nuclear weapons. While the intention of the dome would be to make America safer, it could do the opposite. A commonly cited anecdote, known as the cobra effect, offers a warning about best-laid plans. This anecdote purports that British officials in colonial India offered a bounty for dead cobras; residents allegedly began breeding them for the reward, and when the bounty ended, the snakes were released which made the metropolitan areas in India more unsafe. A policy intended to reduce the cobra population produced the opposite result. The same could be true of the Golden Dome and must be considered in the calculus for its implementation.  

Concerns for Golden Dome go beyond the dome antimissile defense. A shield intended to reduce American vulnerability could make an adversary feel more exposed, encouraging it to build or diversify forces in other areas. Russia condemned Golden Dome arguing weapons in space are a provocation and they militarize space. The Soviets had a similar reaction to the Star Wars program. Russia may simply build more missiles and decoys to ensure enough survive. Russia is positioned to do so with impunity given that New START expired in February 2026. For the first time in decades the largest arsenals on earth are no longer bound by a bilateral cap.  

Whoever follows Putin may well prove worse. Even thought the forgoing text focusses on Russia, other adversaries are not far behind. North Korea continues to expand and diversify its nuclear and ballistic-missile capabilities. China continues a major expansion of its nuclear and missile forces. An even with the assassination of Supreme Leader Ali Khamenei, the Iranian regime continues to show an unwillingness to curb their pursuit of missiles and weapons of mass destruction.  

Will Russia’s current nuclear weapons levels increase like the cobras in India? It is unknown, but regardless, the argument for the dome is strong. An imperfect defense would still complicate Russia’s planning and could improve protection against limited or accidental launches. Golden Dome could make America safer, however there is risk that it may do the opposite; no one can yet say. However, uncertainty is not a reason to abandon the concept, but a reason to keep exploring and to field it once it is ready. The dangers are not diminishing, and the world is growing less predictable. A nation must mitigate the dangers that exist and find a way not to release the bounty on the cobras.

Hypersonic technology encompasses both aircraft and missiles that travel at speeds exceeding five times the speed of sound. These vehicles leverage advanced propulsion systems, such as scramjets (supersonic combustion ramjets), to achieve and sustain such high velocities. The potential applications of hypersonic technology are vast, ranging from rapid global strike capabilities to enhanced missile defense systems.

However, interest in hypersonic technology is not new. Scientific research began during the Cold War, but only in recent years have significant breakthroughs been made towards advancing hypersonic technology from theory to practicality. The primary drivers of this renewed focus include advancements in materials science, computational fluid dynamics, and propulsion technology. Nations such as the United States, China, and Russia are at the forefront of hypersonic research, each vying for technological supremacy, with China and Russia attempting to challenge the status quo.

The strategic advantages of hypersonic technology are multifaceted. One of the most significant benefits is the ability to deliver payloads at unprecedented speeds, drastically reducing the time available for adversaries to detect, track, and intercept these threats. This capability enhances both offensive and defensive operations.

Hypersonic vehicles can reach their targets much faster than conventional missiles or aircraft. This rapid response capability is crucial in scenarios requiring immediate action, such as neutralizing high-value targets or responding to emerging threats. The ability to strike quickly and precisely could deter adversaries from initiating conflict, knowing that retaliation would be swift and devastating.

The high speed and maneuverability of hypersonic vehicles make them difficult to detect and intercept. Traditional air defense systems, designed to counter slower, more predictable threats, may struggle to adapt to the dynamic flight paths of hypersonic weapons. This enhanced survivability increases the likelihood of mission success, particularly in contested environments.

Hypersonic vehicles can cover vast distances in a short amount of time, providing global reach without the need for forward-deployed bases.

This capability is especially valuable for nations looking to project power and influence across the globe. It also reduces the logistical burden associated with maintaining overseas bases and allows for more flexible deployment strategies.

Despite their potential, hypersonic technologies face significant technological challenges. Overcoming these obstacles is essential for the successful development and deployment of hypersonic systems.

One of the primary challenges is managing the extreme heat generated during hypersonic flight. At speeds exceeding Mach 5, air friction can cause the surface temperature of a vehicle to reach several thousand degrees Celsius. Developing materials and cooling systems capable of withstanding and dissipating this heat is crucial to maintaining the structural integrity and performance of hypersonic vehicles.

The materials used in hypersonic vehicles must endure not only high temperatures but also extreme pressures and aerodynamic forces. Advanced composites, ceramics, and metal alloys are being developed to meet these demanding requirements. Researchers are also exploring innovative manufacturing techniques, such as additive manufacturing, to create components with enhanced durability and performance.

Maintaining control and accuracy at hypersonic speeds is another significant challenge. Hypersonic vehicles must navigate through rapidly changing atmospheric conditions, requiring sophisticated guidance and control systems. These systems must be able to make real-time adjustments to the vehicle’s trajectory, ensuring that it stays on course and reaches its intended target.

Developing reliable propulsion systems capable of sustained hypersonic flight is a major technological hurdle. Scramjets, which operate efficiently at hypersonic speeds, are still in the experimental stage. Achieving a balance between thrust, fuel efficiency, and structural integrity is critical for the success of these systems.

The deployment of hypersonic technology has profound strategic implications for global security. As nations race to develop and deploy hypersonic weapons, the balance of power could shift, necessitating new defense strategies and international regulations.

The development of hypersonic technology has the potential to trigger an arms race among major powers. Nations may feel compelled to develop their own hypersonic capabilities or invest in advanced defense systems to counter these threats. This escalation could lead to increased military spending and heightened tensions on the global stage.

Hypersonic weapons could enhance deterrence by providing a credible and rapid response option. However, their deployment also raises the risk of miscalculation and escalation. The speed and unpredictability of hypersonic weapons could shorten decision-making windows, increasing the likelihood of accidental or preemptive strikes. That said, the opportunity to discuss potential gains and losses for both development and implementation of hypersonic weapons is an opportunity to help drive future strategy development.

Developing effective countermeasures against hypersonic threats is a priority for many nations. Advanced radar systems, directed-energy weapons, and missile defense systems are being explored as potential solutions. Integrating these technologies into existing defense frameworks is essential for maintaining a robust defense posture.

The proliferation of hypersonic technology underscores the need for international regulations and agreements. Establishing norms and guidelines for the development, testing, and deployment of hypersonic weapons could help mitigate the risks associated with their use. Diplomatic efforts to promote transparency and confidence-building measures are crucial for maintaining global stability.

Regardless of the naysayers, hypersonic technology represents the next frontier in military airpower, offering unparalleled speed, agility, and reach. While the strategic advantages are significant, the technological challenges and strategic implications cannot be overlooked. As nations continue to invest in hypersonic research and development, the race for air superiority will intensify, shaping the future of global security. Balancing the benefits and risks of hypersonic technology will be essential for ensuring a stable and secure international environment.
