Global military technologies in the 21st century: Analysis of new weapon systems from blackout bombs and railguns to laser defense

Military technology: The new frontiers of warfare

Which new military technologies from Asia are currently in focus?

In an era of increasing geopolitical tensions, the development of advanced military technologies is increasingly coming into the public and strategic spotlight. Recent presentations from China, Japan, and Turkey reveal specific technological vectors that could potentially alter the nature of modern conflict. China has unveiled a land-based missile system for disabling power grids using graphite submunitions. Japan is advancing the development of a ship-based electromagnetic railgun that utilizes kinetic energy as its primary weapon. Turkey has developed the Yildirim-100, a laser-based missile defense system for helicopters, known by the technical term Directed Infrared Countermeasures (DIRCM). These three systems are not isolated technological curiosities, however. Rather, they are representative examples of broader, global trends in modern military development: the focus on infrastructure warfare, the maturation of directed-energy weapons, and the proliferation of sophisticated electronic defense systems.

Why is the analysis of these systems crucial for understanding modern conflicts?

The in-depth analysis of these and other novel weapons systems is crucial for understanding the dynamics of modern and future conflicts. Technology is a primary driver of strategic change. Understanding the specific capabilities, operational limitations, and strategic doctrines behind these new weapons enables a well-informed assessment of geopolitical tensions and the stability of the global security architecture. Studying these systems reveals not only what is technologically possible but also how states intend to fight in future conflicts. It illuminates the transition from traditional, attrition-based warfare to concepts aimed at system collapse, information dominance, and asymmetric advantages. Thus, engaging with these technologies is essential for discerning the contours of the 21st-century battlefield and understanding the resulting implications for deterrence, defense, and international security.

Analysis of the presented technologies

The graphite bomb – Targeted paralysis of infrastructure

What is the function and strategic purpose of the graphite bomb developed by China?

The weapon system, unveiled by Chinese state media, is a land-based missile with a range of 290 kilometers and a 490-kilogram warhead. Its purpose is not destruction through a conventional explosion, but rather the targeted disruption of an adversary's electrical infrastructure. The missile releases 90 cylindrical submunitions that detonate upon impact in the air, dispersing a cloud of fine, chemically treated carbon filaments over a target area of ​​approximately 10,000 square meters. These highly conductive filaments adhere to high-voltage infrastructure such as power lines, transformers, and switchgear, causing massive short circuits.

The strategic purpose of this weapon, often referred to as a “blackout bomb” or “soft bomb,” is to paralyze an adversary’s operational systems. Rather than directly destroying enemy troops, the weapon aims to cripple command centers, communication networks, and critical civilian infrastructure such as hospitals and airports by disrupting their power supply. Military analyses frequently identify Taiwan as the primary potential target for such a Chinese attack. Its power grid is considered outdated and extremely vulnerable in the event of conflict. A Chinese military journal estimated that a simultaneous attack on just three major substations in Taiwan could cause a 99.7 percent disruption of the grid.

Is this a completely new technology?

Graphite bomb technology is by no means new. The United States and NATO developed and deployed such weapons decades ago. The innovation of the Chinese system appears to lie in its specific delivery platform: a land-based missile. This offers different tactical possibilities compared to the air-launched bombs or cruise missiles previously used by Western armed forces, particularly for a rapid first strike without first establishing air superiority. Other nations, such as South Korea, have also announced the development of graphite bombs to cripple North Korea's power grid in the event of war.

What technical details characterize modern systems like the BLU-114/B and its carrier systems?

The standard submunition of the US armed forces is the BLU-114/B, a small, non-explosive aluminum canister roughly the size of a soda can. These submunitions are typically released from a larger cluster bomb, such as the CBU-94 "Blackout Bomb." A single SUU-66/B canister can carry 202 BLU-114/B units. Each of these submunitions is equipped with a small parachute to stabilize and slow its descent and contains spools of fine, conductive fibers. Historically, delivery systems have included tactical aircraft such as the F-117 Nighthawk stealth bomber, which dropped the CBU-94, and sea-launched Tomahawk cruise missiles, which were fitted with special warheads (Kit-2) that also contained the carbon filaments. The filaments themselves are extremely thin and chemically treated to float in the air like a dense cloud, thus maximizing contact with unprotected electrical components.

What effectiveness and limitations have graphite bombs demonstrated in practice?

The weapon's effectiveness has been strikingly demonstrated in past conflicts. During the 1991 Gulf War, the US successfully crippled 85% of Iraq's power supply with its use. In the 1999 Kosovo War, NATO attacks with graphite bombs on Serbia resulted in a 70% failure of the national power grid. The weapon is considered "soft" because it causes minimal direct physical damage to infrastructure and does not immediately kill people, making it appear a comparatively "humane" option.

The crucial limitation, however, is the time it takes for the weapon to work. In Serbia, technicians managed to restore power within 24 to 48 hours. This ultimately forced NATO to resort to conventional bombs to permanently destroy power plants and power lines. Furthermore, the weapon's effectiveness depends on the nature of the target infrastructure; the filaments only function on uninsulated overhead power lines. However, completely isolating power grids is usually not feasible in practice due to the enormous costs involved.

An often overlooked but critical aspect is the severe humanitarian repercussions. Power outages also cripple water supply and sewage treatment systems. In the past, this has directly led to outbreaks of cholera and other waterborne diseases, resulting in numerous civilian deaths. This consequence stands in stark contrast to the classification of the weapon as “humane.”.

China's revival of this technology, despite its known limitations, suggests a strategic focus on so-called "system disruption warfare." The weapon is not intended as a sole, war-deciding weapon, but rather as a precursor to an initial attack wave. A brief but widespread power outage would have devastating consequences for a modern, technologically dependent society and its military. The goal is not permanent destruction, but rather to inflict systemic shock and paralysis. By disrupting the power supply, China could disrupt Taiwan's command and control structures, air defense coordination, and public communications during the most critical initial phase of an invasion. This temporary paralysis creates a window of opportunity in which subsequent forces, such as amphibious assault units or airborne troops, can operate with significantly reduced resistance. The land-based missile system offers a rapid and potentially surprising method of attack that, unlike a bomber-dropped system, does not require prior air superiority. This demonstrates a sophisticated understanding of multidimensional, sequenced operations. The graphite bomb is not the actual attack; it is the key that unlocks the door to the actual attack.

The Railgun – Kinetic Energy as a Weapon of the Future?

What are the technical characteristics and objectives of the Japanese railgun program?

The Japanese railgun program, which began in 2016 under the leadership of the Ministry of Defense's Acquisition, Technology & Logistics Agency (ATLA), has made remarkable progress. Sea trials are taking place aboard the test vessel JS Asuka, which has a prototype of the weapon installed. In tests, the system achieved a muzzle velocity of approximately Mach 6.5 (about 2,230 meters per second) with a muzzle energy of five megajoules (MJ). A long-term goal is to increase the energy to 20 MJ. One of the most significant technical achievements is the stated barrel life of over 120 rounds—a critical hurdle that has caused other programs to fail.

The strategic purpose of the program is to develop a cost-effective defense against modern threats, particularly against the hypersonic missiles of China and Russia, as well as against drone swarms. Cost-effectiveness is a key factor: the cost per projectile is estimated at approximately US$25,000, compared to US$500,000 to US$1.5 million for an interceptor missile. This addresses the fundamental problems of magazine depth and cost per shot in an intense conflict scenario.

What are the fundamental technical challenges in the development of railguns?

The development of railguns is associated with enormous technical hurdles that were considered insurmountable for decades.

Running or rail erosion: The immense electrical currents and magnetic forces required to accelerate the projectile generate extreme heat and pressure. This leads to very rapid physical wear or even the melting of the conductive rails, which is considered the single biggest obstacle.

Power generation and thermal management: Railguns require massive, short bursts of power, necessitating large capacitor banks and powerful onboard generators. Only the most advanced warships, such as the US Navy's Zumwalt-class destroyers, were considered sufficiently powerful. The system also generates enormous amounts of waste heat, which must be effectively dissipated to maintain an acceptable rate of fire.

Rate of fire: The time required to recharge the capacitors between shots can severely limit the rate of fire. This makes it difficult to use the weapon for defense against multiple or rapidly approaching targets such as missiles.

Why was the US Navy's ambitious railgun program discontinued, and how does it compare to Japanese progress?

The US Navy's railgun program ran for 15 years and cost $500 million before being canceled in 2021. The official reasons for the cancellation were "fiscal constraints, challenges in integrating it into combat systems, and the anticipated technological maturation of other weapon concepts." The core of the technical failure was the barrel's insufficient lifespan. The US prototype, which aimed for a significantly higher energy level of 32-33 MJ, could fire no more than a dozen or two rounds before the barrel was destroyed. Furthermore, its rate of fire was too low for missile defense purposes.

In comparison, Japan pursued a more pragmatic approach. While the US aimed for a long-range (over 100 nautical miles) and high-energy offensive weapon, pushing materials science to its limits, Japan focused on a lower-energy system (5 MJ), likely intended for defensive purposes. This more modest approach allowed them to overcome the barrel life issue (over 120 rounds) and develop a working prototype. Although the US program was more ambitious, Japan's pragmatism has positioned it to take the lead in bringing a functioning system into service. China is also known to have a naval railgun program; a weapon was spotted on a test vessel in 2018.

What strategic role should railguns play in modern naval warfare?

The strategic role of railguns lies primarily in cost-effective defense and the solution of fundamental logistical problems in modern naval warfare.

Cost-effective defense: Its primary task is seen as defending against saturation attacks by hypersonic missiles, cruise missiles, and drone swarms. The low cost per shot allows for sustained defensive fire in situations where expensive interceptor missiles would be quickly exhausted.

Overcoming magazine limitations: A warship can carry thousands of solid railgun projectiles for the same space and weight as a few dozen large rockets. This fundamentally solves the problem of “running out of ammunition” in a high-intensity conflict.

Flexibility: Railguns can engage targets in the air, at sea, and on land. Unlike lasers, they are not affected by atmospheric conditions and can fire beyond the horizon, giving them a decisive advantage over purely line-of-sight weapons.

Japan's development of a functioning naval railgun represents a potential paradigm shift in defensive naval warfare. It marks the transition from a limited inventory of expensive "silver bullet" interceptor missiles to a system with virtually unlimited, low-cost ammunition. This is a direct response to the emerging doctrine of saturation attacks. Modern maritime threats increasingly rely on overwhelming a ship's defenses with a large number of inexpensive drones or sophisticated, maneuverable hypersonic missiles. An Aegis-class destroyer carries 90 to 96 vertical launch system cells (VLS). Each interceptor missile is extremely expensive and can only be used once. In a saturation attack, the ship's magazine can be quickly depleted, leaving it defenseless. The Japanese railgun, with its $25,000 projectiles and the ability to load thousands of rounds, directly addresses this economic and logistical vulnerability. It dramatically alters the cost-benefit ratio in favor of the defender. The strategic value of the railgun therefore lies not only in its speed but also in its sustained power. It enables a warship to repel a massive attack that would otherwise be impossible to defend against. This capability is particularly crucial for Japan, which faces a numerically superior Chinese navy and a growing arsenal of Chinese hypersonic missiles.

Directed Infrared Countermeasures (DIRCM) – Lasers as a protective shield

How does the Turkish Yildirim-100 system work and what is its purpose?

Developed by the Turkish defense company Aselsan, the Yildirim-100 is a directed infrared countermeasure (DIRCM) system. Its operation differs fundamentally from systems that destroy an incoming missile through explosion. Instead, it uses a high-powered, multispectral laser to "blind" or "flash" the missile's infrared seeker (heat seeker). This causes the missile to lose track of the target aircraft and be deflected from its course.

The system consists of missile warning sensors (compatible with both UV and IR-based warning systems), an electronic control unit, and laser turrets. The Yildirim-100 uses a dual-turret configuration to provide complete, 360-degree spherical protection around the aircraft. Its primary purpose is to protect aircraft, particularly helicopters and other platforms, from attacks by infrared-guided missiles, especially man-portable air defense systems (MANPADS). The system has been successfully tested in live-fire exercises, including NATO demonstrations. Aselsan is also developing a more powerful system, the Yildirim-300, for faster aircraft such as fighter jets.

What are the fundamental advantages of DIRCM systems over traditional countermeasures such as flares?

DIRCM systems offer decisive advantages over traditional decoys such as flares, which are due to the further development of missile seeker technology.

Precision and effectiveness: Flares are omnidirectional decoys that attempt to present a hotter target than the aircraft in order to divert the missile. However, modern missile seekers can often distinguish between the short, intense burn of a flare and the steady, specific signature of an aircraft engine, making flares less reliable. DIRCM systems, on the other hand, precisely aim a coded laser beam at the missile seeker, actively disrupting its guidance logic.

Unlimited magazine: Flares are a finite resource; once an aircraft has exhausted its supply, it is defenseless. A DIRCM system is powered by the aircraft's electrical system and can, in principle, operate indefinitely as long as it has power. This allows for defense against multiple, simultaneous threats in a dense, hazardous environment.

Concealment and safety: The use of flares produces a bright, visible signal that can reveal an aircraft's position. DIRCM is a "silent" electronic method. Flares also carry the risk of causing fires or collateral damage when used over populated areas—a concern that does not exist with DIRCM.

What different types of DIRCM systems are being developed and used worldwide?

The technology is dominated by a small number of nations and companies. Key players include Northrop Grumman (USA) with its AN/AAQ-24 Nemesis/Guardian system, Elbit Systems (Israel) with its MUSIC family (J-MUSIC, C-MUSIC, Mini-MUSIC), Leonardo (Italy/UK) with its Miysis system, and BAE Systems. The systems vary in size, weight, and power consumption (SWaP), with specific versions optimized for large transport aircraft (J-MUSIC, LAIRCM), helicopters (Mini-MUSIC, Miysis), and even commercial airliners (C-MUSIC). The core technology often incorporates advanced fiber lasers and highly dynamic, precision mirror turrets to track the threat and direct the laser beam.

What risks are associated with the use of DIRCM systems?

The primary risk associated with the use of DIRCM systems lies in the lack of control over where the deflected missile ultimately lands. While a missile deflected over the open ocean poses little concern, one deflected during an attack over a populated area could crash unpredictably, causing significant collateral damage. This is a major concern in conflicts like the one in Ukraine. Another technological risk is the so-called "home-on-jam" phenomenon. Sophisticated seekers could be able to overcome jamming signals or even use the jamming laser as a targeting signal, thus compromising the defense system. This fuels a constant technological arms race between missile seekers and countermeasures systems.

The proliferation of DIRCM technology, particularly by a rising arms exporter like Turkey, signals a “democratization” of advanced electronic warfare capabilities. This undermines the technological superiority once reserved for a handful of Western nations and alters the risk assessment for air operations worldwide. For decades, advanced systems like DIRCM were the exclusive domain of leading military powers such as the US and Israel. Now, the Turkish company Aselsan is successfully developing, testing, and marketing a competitive system. Given Turkey’s rapidly growing and aggressive arms export industry, which sells high-tech products like Bayraktar drones to dozens of countries, it is logical to assume that systems like the Yildirim-100 are also being offered for export. The widespread availability of effective DIRCM systems makes air power, a traditional asymmetric advantage of major powers, more vulnerable. A nation, or even a non-state actor, equipped with modern MANPADS and aircraft fitted with DIRCM can create a far more contested airspace. This means that any air force operating in a region where Turkish (or other non-Western) systems are present can no longer assume technological superiority in that specific area.

The Security and Defence Hub offers expert advice and up-to-date information to effectively support companies and organizations in strengthening their role in European security and defence policy. Working closely with the SME Connect Defence Working Group, it particularly promotes small and medium-sized enterprises (SMEs) that wish to further develop their innovative capacity and competitiveness in the defence sector. As a central point of contact, the Hub thus creates a crucial bridge between SMEs and European defence strategy.

The age of hypersonic weapons

What are the basic types of hypersonic weapons and how do they differ?

Hypersonic weapons are defined as missiles that travel at more than five times the speed of sound (Mach 5) and are maneuverable within the atmosphere. There are two basic categories:

Hypersonic glide vehicles (HGVs): These are launched to a high altitude by a ballistic missile. There, the glider separates and glides at hypersonic speed along a relatively flat, unpredictable trajectory to its target. Examples include the Russian Avangard and the Chinese DF-ZF, which is carried by the DF-17 missile.

Hypersonic cruise missiles (HCMs): These are powered throughout their flight by advanced, air-breathing engines, typically scramjets, operating at hypersonic speeds. They fly at lower altitudes than hypersonic HGVs. Examples include the Russian Zircon and the US HACM program.

What stage of development have the hypersonic programs of the USA, Russia and China reached?

The race to develop and deploy hypersonic weapons is a central feature of the strategic competition between major powers.

Russia claims to already possess operational systems. The Avangard hypersonic missile was declared operational in 2019 and is said to reach speeds of up to Mach 20. The Zircon hypersonic missile entered service in 2023, with a range of approximately 1,000 km and speeds of Mach 6-8. The Kinzhal, an air-launched ballistic missile often referred to as a hypersonic weapon, has already been used in the war in Ukraine.

China: Considered a leader in this field by the US. The DF-17 missile with its DF-ZF hypersonic glide vehicle reportedly entered service in 2020. Furthermore, in 2021, China conducted a groundbreaking test of a fractional orbital bombardment (FOB) system using a hypersonic glide vehicle, demonstrating potential global range over unpredictable trajectories (e.g., over the South Pole).

USA: After a period of lagging behind, the US has caught up. It is pursuing several programs across all branches of the armed forces that focus exclusively on conventional (non-nuclear) warheads. Key programs include the Army's Long-Range Hypersonic Weapon (LRHW), the Navy's Conventional Prompt Strike (CPS), and the Air Force's Hypersonic Attack Cruise Missile (HACM) and Hypersonic Air-Launched Offensive (HALO). While the US has faced setbacks in testing, it aims to achieve initial operational capability for some systems around 2025.

What strategic shifts result from the introduction of these weapon systems?

The introduction of hypersonic weapons leads to fundamental strategic shifts that threaten the stability of deterrence.

Erosion of traditional missile defense: Their combination of extreme speed and maneuverability makes them exceptionally difficult for conventional air and missile defense systems (such as Patriot or Aegis) to track and intercept. Ground-based radar systems have only a very short window of opportunity for detection due to line-of-sight limitations.

Reduced decision time: The speed of these weapons dramatically reduces the time between detection and impact. This places immense pressure on political and military leaders to make decisions about countermeasures, increasing the risk of miscalculations and unintended escalation.

Improved first-strike capability: They enable the destruction of high-value, time-critical and heavily defended targets (e.g. aircraft carriers, command centers, air defense positions) with very short warning time, increasing the advantage of a surprise first strike.

What concepts are being pursued to defend against hypersonic weapons?

Defending against hypersonic weapons represents one of the greatest technological challenges for modern defense.

Space-based sensing: The key to defense lies in early detection and tracking. The US is developing a multi-layered satellite constellation to enable this. This includes the Space Development Agency's (SDA) Proliferated Warfighter Space Architecture (PWSA) with its wide-angle optical satellite tracking layer (WFOV), and the Missile Defense Agency's (MDA) Hypersonic and Ballistic Tracking Space Sensor (HBTSS), which provides more detailed tracking data. These systems are necessary because hypersonic targets are 10 to 20 times darker than traditional ballistic missiles and are more difficult for existing sensors to detect.

Glide Phase Interceptor (GPI): The US, in cooperation with Japan, is developing the GPI, a new interceptor missile specifically designed to combat hypersonic threats during their glide phase—the longest and most vulnerable part of their flight path. This is a large and complex undertaking, and due to funding and technical challenges, deployment is not expected before the mid-2030s.

Directed energy: In the long term, directed energy weapons such as high-energy lasers or railguns are seen as potential defensive solutions due to their ability to engage targets at the speed of light.

The hypersonic race between Russia, China, and the USA has reached a new dimension in military technology development in recent years. Each of these countries is investing heavily in hypersonic missile technologies, which are characterized by extreme speeds and difficult-to-defend trajectories.

Russia currently leads in this field with several operational systems. The Avangard hypersonic glide vehicle can be deployed globally and reaches speeds exceeding Mach 20. The Zircon missile, deployable from ships and submarines, can reach speeds of Mach 6-8. Particularly noteworthy is the Kinzhal missile, launched from MiG-31K aircraft, which achieves speeds of Mach 10.

China has also made significant progress. The DF-17, equipped with the DF-ZF glide vehicle, can cover distances of 1,800 to 2,500 kilometers and reach speeds exceeding Mach 5. Another project, the FOB-HGV, is currently undergoing testing.

The US is currently developing several hypersonic systems, including the LRHW/CPS glide vehicle, which can utilize mobile platforms and seagoing vessels, as well as airborne systems such as HACM and HALO. These projects are still in the development and testing phase.

The race for hypersonic technologies demonstrates the strategic importance of these weapon systems, which challenge traditional defense systems and could potentially alter the global military balance.

Energy weapons – From defense to destruction

Which high-energy laser (HEL) systems are being developed by the USA and Germany, and what are their primary applications?

The US and Germany are investing significantly in the development of high-energy laser (HEL) systems to create cost-effective solutions against a growing number of threats.

USA: The development extends across all branches of the armed forces.

Navy: Following the testing of the Laser Weapon System (LaWS) on the USS Ponce, the HELIOS (High Energy Laser with Integrated Optical-dazzler and Surveillance) system, with a power output of 60 kW, is now being integrated into Arleigh Burke-class destroyers to counter drones and small boats. An even more powerful 300 kW system called HELCAP is under development to combat anti-ship cruise missiles.

Army: The focus is on mobile air defense. 5 kW lasers have been tested on Stryker wheeled armored vehicles and are now being upgraded to 50 kW. The truck-mounted IFPC-HEL (Indirect Fire Protection Capability – High Energy Laser) system, with a power output of 300 kW, is designed to defend against missiles, artillery and mortars (C-RAM), as well as drones.

Air Force: The possibility of mounting lasers on aircraft such as the AC-130J Ghostrider for ground attack and self-defense is being investigated.

Germany: The main players are Rheinmetall and MBDA. Rheinmetall has successfully tested systems ranging from 10 kW to 50 kW, demonstrating their ability to cut through steel and shoot down drones. A 20 kW laser demonstrator was successfully deployed against drones under real-world conditions on the frigate "Sachsen" in 2022.

The primary applications for HEL systems are defense against low-cost and numerous threats such as drones (C-UAS), missiles, artillery and mortars (C-RAM), and small boats. The decisive advantage is the extremely low cost per shot, estimated at 59 US cents for LaWS, in contrast to expensive interceptor missiles.

What are high-performance microwave weapons (HPMs) and what role do they play in defending against drone swarms?

High-power microwave weapons (HPMs) are a form of directed energy that emits powerful pulses of microwave radiation. They do not physically destroy targets, but are designed to overload and disable or destroy the sensitive electronic circuitry within them. Their primary application is drone swarm defense. A single HPM pulse can potentially disable multiple drones simultaneously over a wide area, making them an ideal defense against swarm saturation attacks. A leading example is the Leonidas system from Epirus, procured by the U.S. Army for low-altitude air defense (LAAD) to protect bases and formations.

What are the physical and operational limitations of directed-energy weapons?

Despite their potential, directed energy weapons are subject to significant limitations.

Atmospheric conditions: Laser beams are attenuated by clouds, rain, fog, and dust, as these elements absorb and scatter the light. This significantly reduces their effective range and power at the target. HPM weapons are less affected by weather conditions.

Line of sight: Energy weapons require a clear, unobstructed line of sight to the target. They cannot be fired over hills or the horizon.

Dwell time: Lasers must remain focused on a point at the target for a specific amount of time to penetrate it. This can be challenging with fast-moving or maneuvering targets.

Power and cooling: These systems require immense electrical power and generate significant waste heat, which poses major challenges for integration on mobile platforms such as vehicles, ships and aircraft.

The parallel development of high-energy lasers (HEL) and high-power microwaves (HPM) reveals a sophisticated, layered approach to countering the drone threat. This is not an either-or decision, but a both-and strategy tailored to different operational scenarios. Lasers offer surgical precision, ideal for taking down individual, high-value drones or for use in chaotic environments where the indiscriminate nature of HPM would be problematic. HPM weapons, on the other hand, offer area coverage, perfect for engaging a large, technologically simple swarm where single-target engagement is impractical. This layered defense model illustrates the complexity of modern warfare. There is no single "miracle weapon." Instead, effective defense requires the integration of multiple, diverse sensor and engagement systems into a single command and control network.

The militarization of new domains: space, AI and quantum technology

What anti-satellite anti-tank (ASAT) capabilities do the leading space powers possess?

The ability to attack and disable an adversary's satellites is considered a crucial factor in future conflicts. There are various types of anti-satellite weapons (ASATs):

Direct-ascent kinetic weapons: A missile is launched from the ground, from the air or from the sea to destroy a satellite with a direct hit.

Co-orbital weapons: A “weapons satellite” is placed into orbit, maneuvers close to a target satellite, and then destroys it.

Non-kinetic weapons: Methods that disrupt or disable a satellite without physically destroying it. These include laser blinding, high-energy microwave attacks, GPS or communication signal jamming, and cyberattacks.

The US (1985, 2008), Russia (most recently 2021), China (2007), and India (2019) have all successfully tested direct-ascending kinetic ASAT weapons by destroying their own satellites. The primary risk of such kinetic tests is the creation of vast amounts of long-lived space debris, which threatens all satellites, including civilian and commercial ones. The 2021 Russian test produced over 1,500 trackable pieces of debris. This increases the risk of the "Kessler syndrome," a cascading chain reaction of collisions that could render low Earth orbit unusable.

Invisible warfare in space is evident in a series of notable events where nations deliberately shoot down satellites. The first documented incident occurred on September 13, 1985, when the US successfully destroyed a satellite at an altitude of 555 kilometers using the ASM-135 ASAT missile system during the Cold War. A particularly high-profile moment was the Chinese test on January 11, 2007, in which the Fengyun-1C satellite was destroyed at an altitude of 865 kilometers, leaving behind a massive debris field that served as a wake-up call for the international community.

The US conducted a similar operation on February 21, 2008, officially to protect against falling toxic fuel. India demonstrated its ASAT capabilities on March 27, 2019, with the Shakti mission, destroying the Microsat-R satellite at an altitude of 283 kilometers. The most recent significant incident occurred on November 15, 2021, when Russia, using the A-235 system (Nudol), destroyed the Kosmos 1408 satellite at an altitude of approximately 465 kilometers, creating over 1,500 pieces of debris that even threatened the International Space Station.

These incidents highlight the growing importance of space as a potential conflict zone and the increasing militarization of space travel by various nations.

What is the concept of the All Domains Joint Command and Control System (JADC2) and what role does AI play in it?

The Joint All-Domain Command and Control System (JADC2) is the Pentagon's vision to connect all sensors from all branches of the armed forces (Army, Navy, Air Force, etc.) and all domains (air, land, sea, space, cyber) into a single, unified network. The goal is to provide commanders with a complete situational awareness picture and enable each sensor to relay target data to the most appropriate "shooter," regardless of branch of service. This is intended to dramatically accelerate decision-making and reaction time, which is essential for engaging formidable adversaries such as China and Russia.

The role of artificial intelligence (AI) is fundamental. Humans cannot process the sheer volume of data from thousands of sensors in real time. AI and machine learning are essential for fusing this data, identifying targets, detecting threats, and recommending courses of action to human commanders. AI is the “brain” that will make the JADC2 network operational. The Pentagon is conducting global experiments (GIDE) to mature this technology.

What military potential do quantum technologies hold in the areas of sensor technology and communication?

Quantum technologies promise revolutionary military capabilities, even though many are still in an early stage of development.

Quantum sensing: This is the most advanced area of ​​quantum technology. It uses the principles of quantum mechanics to build sensors of unprecedented precision.

Navigation: Quantum gyroscopes and accelerometers could enable highly precise navigation for submarines, ships and aircraft without relying on the vulnerable GPS system.

Detection: Quantum magnetometers could potentially detect the tiny magnetic disturbances caused by submarines. This could make the oceans “transparent” and threaten the survivability of strategic ballistic missile submarines, a cornerstone of nuclear deterrence.

Quantum communication: It uses quantum entanglement to theoretically create "tapping-proof" communication channels. Any attempt to eavesdrop on the communication would disrupt the system and be immediately detected. This would be invaluable for secure military and governmental communication, but still faces significant practical challenges.

How are autonomous weapon systems and drone swarms changing tactical and strategic warfare?

The concept of the drone swarm involves the use of a large number of networked, autonomous drones that operate as a coordinated whole.

Tactical implications: Swarms can overwhelm traditional defense systems through sheer numbers. They can conduct distributed reconnaissance, serve as a resilient communications network, and launch complex attacks from multiple directions simultaneously.

Strategic implications: The low cost of individual drones, often composed of commercial components, makes it possible to generate “mass” on the battlefield at an affordable price. This empowers smaller nations or even non-state actors to challenge larger, more technologically advanced militaries – a key feature of asymmetric warfare.

The technologies in this section are not merely individual weapon systems; they are fundamental capabilities that will define the entire architecture of future warfare. They represent a shift from a focus on “platforms” (tanks, ships, aircraft) to a focus on “networks” and “information.” A future conflict between major powers might not begin with a traditional invasion, but rather with a struggle for information dominance. The first shots could be cyberattacks and ASAT attacks aimed at crippling the opponent’s JADC2 network. The side whose network survives or can operate effectively in a degraded mode (e.g., through quantum navigation) will be able to direct its forces effectively, while the other side is deaf and blind. This elevates the importance of domains such as space and cyber from supporting roles to the primary, decisive battlefields.

Strategic, legal and economic context

Doctrines and strategies of the major powers

How do the US national defense strategy and China's modernization goals shape technological armaments?

The national strategies of the USA and China are in direct technological competition and significantly shape the global arms dynamics.

USA: The 2022 National Defense Strategy (NDS) identifies China as the “pacing challenge.” The strategy focuses on “integrated deterrence,” “campaigning,” and “building lasting advantages.” Technologically, this means prioritizing 14 critical technology areas, including AI, hypersonic technology, directed energy, and space technology. A strong emphasis is placed on jointness across the armed forces (JADC2), accelerating the transition from prototype to operational capability, and leveraging partnerships with allies and the commercial technology sector to achieve an “asymmetric advantage.”.

China: China's goals are explicitly time-bound: military modernization by 2027 (the centenary of the People's Liberation Army, with a focus on readiness for a Taiwan conflict), completion of the transformation into an "intelligent" military by 2035, and achieving the status of a "world-class" military power on par with the US by 2049. This strategy drives massive investments in the same key technologies as the US—AI, hypersonic technology, naval power, and space—with the aim of achieving technological parity or superiority to counter US military power, particularly in the Indo-Pacific region.

What lies behind the “Gerasimov Doctrine” and how is the concept of hybrid warfare interpreted?

The “Gerasimov Doctrine” is a term coined by Western analysts, not an official Russian doctrine. It is based on a 2013 article by Russian General Valery Gerasimov. The concept describes a view of modern warfare in which the boundaries between war and peace are blurred, and a wide range of non-military instruments (political, economic, informational, diplomatic) are used in conjunction with military force to achieve strategic objectives. The doctrine is often interpreted as calling for a 4:1 ratio of non-military to military actions.

The interpretation of this concept, however, is controversial. Many experts, including the term's originator, Mark Galeotti, argue that it is a misinterpretation. They maintain that Gerasimov was describing Western tactics (e.g., "color revolutions") and demanding that Russia develop countermeasures, rather than outlining a new Russian offensive doctrine. The concept is more accurately viewed as an operational approach within Russia's broader foreign policy framework (the "Primakov Doctrine"), in which military power enables and underpins these "hybrid" or "gray area" activities.

Legal and ethical limits of automation

What challenges does the use of lethal autonomous weapons systems (LAWS) pose to international humanitarian law?

Lethal autonomous weapon systems (LAWS) are weapon systems that, once activated, can independently search for, identify, target, and kill people without direct human control. Their potential use poses fundamental challenges to international humanitarian law (IHL).

Discrimination principle: How can a machine reliably distinguish between a combatant and a civilian, or between a combatant who is surrendering or wounded (hors de combat)? This often requires nuanced, context-dependent human judgment that is difficult to codify in an algorithm.

Proportionality principle: How can a machine make the complex, subjective assessment of whether the expected collateral damage to civilians is excessive in relation to the expected military advantage? This is a uniquely human evaluation.

Martens Clause: This clause requires that new weapons comply with the “principles of humanity” and the “demands of public conscience.” Delegating life-and-death decisions to a machine lacking compassion or an understanding of the value of human life is considered by many to be a violation of this principle.

Accountability gap: If a LAWS malfunctions and commits a war crime, who is responsible? The programmer, the manufacturer, the commander who deployed it? Assigning criminal responsibility for the unpredictable actions of a complex autonomous system could be legally challenging.

What are the central arguments of the campaign to end killer robots?

The “Campaign to End Killer Robots” is a global coalition of non-governmental organizations advocating for a preventative ban on LAWS (Laser Action Wings). Its main arguments are:

Digital dehumanization: The campaign argues that allowing machines to make killing decisions is the ultimate step in digital dehumanization, reducing humans to data points to be processed and eliminated. This sets a dangerous precedent for the use of AI in other areas of life.

Bias and discrimination: AI systems are trained with data. If this data reflects existing societal prejudices, the AI ​​will replicate and reinforce them. Facial recognition, for example, has been shown to be less accurate with women and people of color, which could lead to discriminatory targeting.

Meaningful human control: The core demand is a new international treaty that ensures “meaningful human control” over the use of force. The campaign argues that machines lack the understanding, context, and ethical capacity for such complex life-and-death decisions and that humans must remain involved in the decision-making process.

The economics of high-tech weapons

What costs are associated with the development and procurement of modern weapons systems?

The costs of developing and procuring modern weapons systems are astronomical and represent a significant burden on defense budgets. The US budget for research, development, testing, and evaluation (RDT&E) alone for fiscal year 2024 was $145 billion.

Hypersonic weapons: The US Navy's CPS missile is estimated to cost over $50 million per unit. The Air Force's ARRW is estimated at $15-18 million per missile. This stands in stark contrast to a Tomahawk cruise missile, which costs approximately $2 million. The Pentagon has spent over $8 billion on hypersonic research since 2019 and plans to invest another $13 billion by 2027.

AI and autonomous systems: Although the costs of individual programs are difficult to isolate, the overall investments are massive. The JADC2 concept is a multi-billion-dollar project.

How has the financing of research and development in the defense sector changed?

The landscape of research and development (R&D) funding has fundamentally changed.

Shift from public to private: In 1960, the US federal government funded approximately 65% ​​of all R&D in the country. By 2019, this share had fallen to just 21%, while the private sector's share had risen to 71%.

Implications for the Department of Defense: The Department of Defense is no longer the primary driver of technological innovation. It must increasingly rely on and adapt technologies developed by the commercial sector. This presents challenges, as the defense procurement process is slow and bureaucratic, while the commercial sector moves quickly.

Consolidation of the industrial base: The US defense industry has consolidated dramatically, from over 50 main contractors to fewer than 10. This reduces competition and can stifle innovation. The NDS and related strategies explicitly call for greater collaboration with smaller, non-traditional companies to counteract this trend.

There is a fundamental and growing tension between the strategic desire for technologically superior, “exquisite” weapons (such as hypersonic missiles) and the economic reality of their staggering costs. This tension forces a strategic division of the arsenal: a small number of very expensive “silver bullets” for high-value targets and a large number of inexpensive, “good enough” systems (drones, lasers) for mass and attrition. No country, not even the US, can afford to buy thousands of $50 million missiles. This budgetary reality forces prioritization. Militaries implicitly create a two-tiered arsenal. Tier 1 consists of a limited number of very expensive, high-performance systems reserved for destroying the most critical, heavily defended enemy targets. Tier 2 consists of a large number of cheap, often expendable or reusable systems designed to control the wider battlespace, absorb losses, and overwhelm less critical targets. The winner of a future conflict may not be the side with the most advanced single weapon, but the side that best masters the economics of this high-low technology mix.

A new arms race?

What overarching trends can be identified in global military technology development?

The analysis of the presented and other global military technologies reveals several overarching trends that define the strategic environment of the 21st century. First, there is a clear shift from warfare focused on attrition to systems-disruption warfare, which prioritizes the paralysis of enemy infrastructure and command structures. Second, a classic offensive-defensive arms race is taking place in new technological dimensions, as demonstrated by the development of hypersonic weapons and their associated defense systems. Third, AI and autonomy are leading to a dramatic acceleration and automation of warfare, placing human decision-making under extreme time pressure. Fourth, non-kinetic and information-centric domains such as space and cyberspace are gaining crucial, if not primary, importance. Fifth, the “democratization” of advanced technologies, such as drones and electronic countermeasures, is leading to an increase in asymmetric threats that challenge the superiority of traditional military powers. Ultimately, the economics of armaments creates a tension between extremely expensive, highly specialized systems and the need to provide cost-effective mass for extended conflicts.

What implications does this have for the future global security architecture?

These technological trends are leading to a more complex and potentially more unstable world. The erosion of traditional deterrent mechanisms by weapons that are difficult to defend against, the extreme speed of potential conflicts, and the blurring lines between war and peace increase the risk of miscalculations and unintended escalation. The legal and ethical gray areas, particularly in the field of autonomous weapons systems, create uncertainty and the danger of dehumanizing conflict. Managing this new technological era requires more than just developing new weapons. It demands new, adaptable doctrines, the establishment of new international norms and rules of conduct, especially in space and cyberspace, and a fundamentally new way of thinking about security and stability. The 21st-century arms race will be decided not only by the quality of technology but also by the ability to manage its strategic, ethical, and economic implications.
