2. **HELSI: The Strategic Imperative Behind Laser Scaling**The development of Lockheed Martin’s 500 kW-class laser is firmly anchored within the broader framework of the High Energy Laser Scaling Initiative (HELSI), a program sponsored by the US Department of Defense. HELSI is a critical national endeavor, meticulously designed to bolster the nation’s defense capabilities by pushing the boundaries of high-powered laser weapon systems. Its overarching goal is to advance these systems for eventual integration across all branches of the US military, ensuring a unified and formidable directed energy posture.
This initiative is not merely about increasing power; it is about strategically scaling laser technology to meet evolving threats. HELSI envisions the development of laser systems across a spectrum of power ranges, specifically targeting the 300-, 500-, and 1000-kW classes. This tiered approach aims to provide a versatile array of defensive tools, capable of engaging powerful targets such as cruise missiles, as noted in an April 2023 Government Accountability Office report, thereby offering unprecedented protection against sophisticated aerial threats.
Lockheed Martin’s recent advancements in laser power optimization are regarded as significant milestones within this ongoing initiative. The current phase of HELSI is particularly focused on proving the capability of these higher power levels while simultaneously achieving optimal beam quality and operational efficiency.

3. **The 300 kW Predecessor: A Foundation for High Energy**Before the 500 kW-class laser, Lockheed Martin had already achieved a significant breakthrough with its 300 kW-class High Energy Laser Weapon System (HELWS) under the HELSI program. This earlier system served as a crucial proving ground, showcasing the immense potential of directed energy weapons (DEW) and their viability for integration into existing defense architectures. Its successful delivery in September 2022 marked a pivotal moment in the US Army’s strategic efforts to incorporate high-energy laser technology into its defensive systems.
The HELWS was configured as a mobile laser system, demonstrating formidable counter-unmanned aerial system (C-UAS) capabilities. This attribute is particularly vital in contemporary conflicts where drone proliferation poses a rapidly escalating and asymmetrical threat. The system was a key component of the US Army’s Indirect Fire Protection Capability-High Energy Laser (IFPC-HEL) program, signifying its role in an integrated approach to air and missile defense.
Lockheed Martin’s expertise in this field was recognized in 2019 when it was selected for an $83 million contract to further advance its spectral beam combined high-energy laser architecture. The timely and successful delivery of the 300 kW-class laser, even ahead of schedule, highlighted the inherent advantages of directed energy laser weapons. These include their lightweight hardware, capacity for instantaneous target engagement, significantly reduced logistical requirements, unparalleled precision, and the crucial benefit of limited collateral damage, all of which define the cutting edge of modern military defense.

4. **Operational Mechanics: How Laser Weapons Function**Laser weapons, at their core, represent a sophisticated application of physics to military defense, utilizing highly concentrated and coherent beams of light to engage and neutralize enemy assets. Their operational efficacy is predicated on the meticulous control and direction of these intense energy streams. This is achieved through advanced beam-control optics and sophisticated software algorithms, which work in concert to focus and precisely guide the laser beam toward its intended targets with extraordinary accuracy.
The generation of such powerful beams typically involves combining multiple kilowatt fiber lasers. This process, often referred to as ‘spectral beam combining’ (SBC) or ‘wavelength beam combining,’ superimposes several laser emitter outputs at distinct wavelengths to forge a single, immensely potent beam. This technique allows for the scalable production of high-energy outputs while maintaining superior beam quality, a critical factor for effectiveness over long distances.
Crucially, these systems are equipped with mechanisms to compensate for atmospheric distortions, such as turbulence, humidity, and particulate matter. These environmental factors can degrade beam quality and reduce accuracy, especially over extended ranges. By dynamically adjusting the beam in real-time, laser weapons ensure improved accuracy and sustained destructive power, mitigating the natural challenges of transmitting intense light through varying atmospheric conditions. This makes them versatile across diverse operational environments.

Summary: A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser originated as an acronym for light amplification by stimulated emission of radiation. The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow and the optical amplifier patented by Gordon Gould.
A laser differs from other sources of light in that it emits light that is coherent. Spatial coherence allows a laser to be focused to a tight spot, enabling uses such as optical communication, laser cutting, and lithography. It also allows a laser beam to stay narrow over great distances (collimation), used in laser pointers, lidar, and free-space optical communication. Lasers can also have high temporal coherence, which permits them to emit light with a very narrow frequency spectrum. Temporal coherence can also be used to produce ultrashort pulses of light with a broad spectrum but durations measured in attoseconds.
Lasers are used in fiber-optic and free-space optical communications, optical disc drives, laser printers, barcode scanners, semiconductor chip manufacturing (photolithography, etching), laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and measuring range and speed, and in laser lighting displays for entertainment. The laser is regarded as one of the greatest inventions of the 20th century.

5. **The Speed-of-Light Advantage: Instantaneous Engagement**One of the most compelling advantages offered by laser weapons is their ability to engage targets at the speed of light, enabling near-instantaneous impact over extended ranges. This attribute is transformative in combat scenarios, fundamentally altering the dynamics of engagement by drastically reducing a target’s window to react or implement defensive countermeasures. In an age where threats can emerge and move with increasing velocity, this unparalleled speed offers a critical tactical advantage.
This rapid response capability provides an essential layer of defense against fast-moving projectiles such as missiles, rockets, and advanced drones. Unlike traditional munitions that require travel time, a laser beam reaches its target almost immediately, drastically cutting down on engagement timelines. This inherent speed allows for multiple engagements in rapid succession, a critical feature when facing swarm attacks or complex, multi-layered threats.
Ultimately, this speed-of-light delivery holds the promise of unprecedented protection against major threats that have historically posed an unbalanced challenge. For decades, the cost and effectiveness of missiles have often outweighed those of the vehicles they target, such as tanks, planes, and ships. Laser weapons could reverse this equation, offering a means to ‘zap’ incoming projectiles before they reach their targets, thereby making traditional kinetic attacks less effective and profoundly reshaping the calculus of deterrence and defense.
Military equipment: Brake-by-wire
Categories: All Wikipedia articles in need of updating, All articles lacking in-text citations, All articles needing expert attention, Articles lacking in-text citations from April 2017, Articles needing expert attention from July 2018
Summary: Brake-by-wire technology in the automotive industry is the ability to control brakes through electronic means, without a mechanical connection that transfers force to the physical braking system from a driver input apparatus such as a pedal or lever.
The three main types of brake-by-wire systems are: electronic parking brakes which have, since the turn of the 21st century, become more common; electro-hydraulic brakes (EHB) which can be implemented alongside legacy hydraulic brakes and as of 2020 have found small-scale usage in the automotive industry; and electro-mechanical brakes (EMB) that use no hydraulic fluid, which as of 2020 have yet to be successfully introduced in production vehicles.
Electro-hydraulic braking systems control or boost the pressure applied to the hydraulic pumps through the brake pedal. Safety requires that the system remains fail-operational in the event of a power failure or an electronic software or hardware fault. Traditionally this has been achieved by means of a mechanical linkage between the brake pedal and the brake master cylinder. With a mechanical linkage, the braking system still operates hydraulically via the pedal, whether or not electrical control is present. EHBs can be implemented by-wire, without legacy hydraulic systems and mechanical connections. In such a case, fail-operational redundancy is implemented, allowing the vehicle to brake even if some of the brake systems fail.
Electro-mechanical brakes offer the advantage of reduced braking system volume and weight, less maintenance, easier compatibility with active safety control systems, and absence of toxic braking fluid. Their novel actuation methods such as wedge brakes have kept them, as of 2020, from successfully being introduced in production vehicles.
Since by-wire systems have no mechanical linkages that would provide manual control over the brakes, they require fail-operational redundancy as specified by the ISO 26262 standard level D. Redundant power supplies, sensors, and communication networks are required.

6. **Precision and Minimizing Collateral Damage**Beyond their remarkable speed, laser weapons are distinguished by their exceptional precision and accuracy, characteristics that profoundly minimize the risk of collateral damage and unintended casualties. This precise targeting capability is an essential feature, particularly in complex and densely populated operational environments where the safeguarding of civilians and non-combatants is a paramount ethical and strategic consideration. The ability to focus energy on specific vulnerabilities of a threat without broad-area devastation is a game-changer.
The inherent nature of a laser beam allows for highly localized and controlled energy delivery. Unlike explosive projectiles, which scatter shrapnel and blast effects over a wide area, a laser weapon directs its power to a minute point on the target. This focused energy can disable critical components, melt through structures, or disrupt sensitive electronics, all while limiting the impact on surrounding infrastructure or personnel. This selective destructive capability is a hallmark of directed energy.
Furthermore, the sophisticated beam control systems integrated into modern laser weapons enable the adjustment of the beam’s intensity and duration. This allows for ‘scalable effects,’ meaning the type and intensity of energy directed at targets can be varied to achieve desired outcomes, from non-lethal disabling to complete neutralization. This level of control, exemplifying the UK’s DragonFire laser’s ability to hit a target as small as a £1 coin a kilometer away, makes laser weapons an indispensable tool for surgical engagements and upholding precision in warfare.
Military equipment: Collateral damage
Categories: All articles lacking reliable references, Articles containing German-language text, Articles lacking reliable references from April 2021, Articles with short description, CS1 German-language sources (de)
Summary: Collateral damage is a term for any incidental and undesired death, injury or other damage inflicted, especially on civilians, as the result of an activity. Originally coined to describe military operations, it is now also used in non-military contexts to refer to negative unintended consequences of an action.
Since the development of precision-guided munitions in the 1970s, military forces often claim to have gone to great lengths to minimize collateral damage.
Critics of use of the term “collateral damage” see it as a euphemism that dehumanizes non-combatants killed or injured during combat, used to reduce the perceived culpability of military leadership in failing to prevent non-combatant casualties.
Collateral damage does not include civilian casualties caused by military operations that are intended to terrorize or kill enemy civilians (e.g., the Bombing of Dresden or Bombing of Hamburg in World War II and Russian strikes against Ukrainian infrastructure openly described as “retaliatory” and intended to “make towns uninhabitable”).

7. **Economic and Logistical Superiority: Low Cost, Deep Magazines**The economic and logistical advantages of laser weapons present a compelling argument for their widespread adoption in military operations. One of the most significant benefits is their cost-effectiveness: the primary operational expense for laser systems revolves around powering the lasers. This contrasts sharply with the exorbitant costs of traditional kinetic munitions, leading to potential long-term savings for defense budgets and a reduced financial burden during sustained combat operations.
Central to this economic advantage is the concept of ‘unlimited ammunition capabilities,’ often referred to as ‘deep magazines.’ As Rick Cordaro of Lockheed Martin explained, this implies that laser weapons can fire continuously as long as they have sufficient electrical power and cooling. Unlike physical ammunition magazines, which are constrained by the number of bullets or shells that can be physically loaded, a laser’s firing capacity is limited only by its energy supply, which can come from onboard generators, batteries, or shipboard power plants.
This translates to a “low cost per engagement,” a military and industry objective to reduce the cost of each ‘zap’ fired by a laser to approximately $1. This is a dramatic reduction when compared to conventional interceptors, such as Patriot missiles, which can cost about $4.1 million apiece. By offering a significantly cheaper method to neutralize certain threats, laser weapons enable militaries to conserve more expensive, limited-stock kinetic tools for threats that lasers are not yet equipped to handle, thereby optimizing resource allocation and enhancing overall strategic flexibility.” , “_words_section1”: “1948

Summary: Deep operation (Russian: Глубокая операция, glubokaya operatsiya), also known as Soviet deep battle, was a military theory developed by the Soviet Union for its armed forces during the 1920s and 1930s. It was a tenet that emphasized destroying, suppressing or disorganizing enemy forces not only at the line of contact but also throughout the depth of the battlefield.
The term comes from Vladimir Triandafillov, an influential military writer, who worked with others to create a military strategy with specialized operational art and tactics. The concept of deep operations was a state strategy, tailored to the economic, cultural and geopolitical position of the Soviet Union. In the aftermath of the failures in the Russo-Japanese War, the First World War, and the Polish–Soviet War the Soviet High Command (Stavka) focused on developing new methods for the conduct of war. This new approach considered military strategy and tactics and introduced a new intermediate level of military art: operations. The Soviet Union’s military was the first to officially distinguish the third level of military thinking which occupied the position between strategy and tactics.
The Soviets developed the concept of deep battle and by 1936 it had become part of the Red Army field regulations. Deep operations had two phases: the tactical deep battle, followed by the exploitation of tactical success, known as the conduct of deep battle operations. Deep battle envisaged the breaking of the enemy’s forward defenses, or tactical zones, through combined arms assaults, which would be followed up by fresh uncommitted mobile operational reserves sent to exploit the strategic depth of an enemy front. The goal of a deep operation was to inflict a decisive strategic defeat on the enemy’s logistical structure and render the defence of their front more difficult, impossible, or irrelevant. Unlike most other doctrines, deep battle stressed combined arms cooperation at all levels: strategic, operational, and tactical.

8. **Diverse Military Applications of Directed Energy Weapons**The strategic potential of directed energy weapons (DEWs) extends far beyond their impressive power specifications, promising to fundamentally reshape defense strategies across a wide spectrum of military operations. These advanced systems are not merely supplemental tools but are poised to become central components in countering a diverse array of modern threats, from aerial assaults to ground engagements. Their versatility enables their application in anti-missile and anti-aircraft defense systems, providing a critical layer of protection against sophisticated ballistic and cruise missile threats, as well as fast-moving aircraft.
Crucially, DEWs are proving indispensable in the escalating challenge of countering hostile drones and drone swarms. Their ability to neutralize unmanned aerial systems (UAS/UAV) rapidly and cost-effectively offers a vital advantage against increasingly prevalent and asymmetrical threats. This capability is particularly significant in contemporary conflicts where the proliferation of drones poses a complex and persistent challenge to conventional defenses, often overwhelming them with sheer numbers or specialized tactics.
Beyond air defense, laser weapons are also designed for engaging surface-to-air and surface-to-surface targets, demonstrating their applicability across various combat domains. Their high precision makes them suitable for surgical strikes, while their inherent speed offers a defensive advantage against incoming ground-launched threats. Furthermore, their integration into naval vessels provides robust shipboard defense, safeguarding critical assets against maritime and aerial adversaries in dynamic oceanic environments.
The utility of DEWs further branches into non-lethal applications, showcasing a spectrum of effects that can be tailored to specific operational requirements. These include sophisticated methods for crowd control, effectively disabling vehicles without causing permanent harm, and employing non-lethal millimeter and microwave devices to debilitate soldiers or incapacitate enemy electronic targets. This nuanced capability allows for graded responses, providing military forces with flexible options that can de-escalate situations or achieve objectives with minimal permanent damage.
Such versatility ensures that DEWs are not merely destructive instruments but multifaceted tools capable of complementing traditional ballistic weapons and offering advanced solutions to address emerging and evolving threats. Their capacity for both hard and soft kill engagements positions them as a pivotal technology for national security and defense strategies, with a clear potential to reshape the paradigms of modern warfare and significantly influence future conflict outcomes.

Summary: The United States Atomic Energy Commission (AEC) was an agency of the United States government established after World War II by the U.S. Congress to foster and control the peacetime development of atomic science and technology. President Harry S. Truman signed the McMahon/Atomic Energy Act on August 1, 1946, transferring the control of atomic energy from military to civilian hands, effective on January 1, 1947. This shift gave the members of the AEC complete control of the plants, laboratories, equipment, and personnel assembled during the war to produce the atomic bomb.
An increasing number of critics during the 1960s charged that the AEC’s regulations were insufficiently rigorous in several important areas, including radiation protection standards, nuclear reactor safety, plant siting, and environmental protection.
By 1974, the AEC’s regulatory programs had come under such strong attack that the U.S. Congress decided to abolish the AEC. The AEC was abolished by the Energy Reorganization Act of 1974, which assigned its functions to two new agencies: the Energy Research and Development Administration and the Nuclear Regulatory Commission. On August 4, 1977, President Jimmy Carter signed into law the Department of Energy Organization Act, which created the Department of Energy. The new agency assumed the responsibilities of the Federal Energy Administration (FEA), the Energy Research and Development Administration (ERDA), the Federal Power Commission (FPC), and various other federal agencies.

9. **Beyond Lasers: Other Directed Energy Weapon Types**While high-energy lasers often dominate discussions surrounding directed energy weapons, the broader category of DEWs encompasses a range of distinct technologies that utilize focused energy to achieve military objectives. A DEW is fundamentally defined as a weapon that employs highly concentrated energy, such as lasers, microwaves, or particle beams, to destroy, harm, or incapacitate its target. These systems are characterized by their capacity to counter quickly, offering missile maneuvering, precision response, and graded reaction capabilities, making them long-range instruments of focused radiation.
Among these diverse types are microwave weapons, which operate within a specific frequency range of 300 MHz to 300 GHz. These systems are engineered to interrupt electronic components, demonstrating a capability to cause varying consequences depending on the energy directed towards the target. Their ability to disrupt critical enemy systems without necessarily causing overt physical destruction makes them a strategic asset for electronic warfare and the neutralization of sophisticated electronic infrastructures.
Particle-Beam DEWs represent another significant class, utilizing a directed flow of energized or neutral particles as their destructive factor. The United States initiated the development of such beam-based devices in the 1970s, alongside other DEW technologies. These weapons are designed for applications against ground forces, in aviation, and, crucially, for targeting space-based assets, highlighting their potential reach across multiple operational domains and their strategic importance in modern space-centric warfare scenarios.
Plasma DEWs further push the boundaries of energy weapon technology by emitting a plasma beam stream—an excited state of matter composed of atomic nuclei and free electrons. This unique form of directed energy offers capabilities such as long-range LASER accuracy, a fast rate of fire, and critically, “scalable effects,” meaning the lethality or impact of the weapon can be precisely altered. This level of control allows for highly adaptable engagements, from disabling to destructive outcomes, enhancing tactical flexibility on the battlefield.
Finally, Sonic Weapons employ sound as their primary mechanism to harm, kill, or incapacitate their victims. These devices typically operate at specific frequencies, ranging from 1 Hz to 30 Hz. While perhaps less widely publicized in the context of high-power military systems than lasers or microwaves, sonic DEWs offer specialized capabilities for crowd control, area denial, and other applications where acoustic energy can achieve desired tactical outcomes.

Summary: A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams. Potential applications of this technology include weapons that target personnel, missiles, vehicles, and optical devices.
In the United States, the Pentagon, DARPA, the Air Force Research Laboratory, United States Army Armament Research Development and Engineering Center, and the Naval Research Laboratory are researching directed-energy weapons to counter ballistic missiles, hypersonic cruise missiles, and hypersonic glide vehicles. These systems of missile defense are expected to come online no sooner than the mid to late 2020s.
China, France, Germany, the United Kingdom, Russia, India, and Israel are also developing military-grade directed-energy weapons, while Iran and Turkey claim to have them in active service. The first use of directed-energy weapons in combat between military forces was claimed to have occurred in Libya in August 2019 by Turkey, which claimed to use the ALKA directed-energy weapon. After decades of research and development, most directed-energy weapons are still at the experimental stage and it remains to be seen if or when they will be deployed as practical, high-performance military weapons.

10. **Challenges and Limitations in DEW Deployment**Despite the formidable advantages and transformative potential of directed energy weapons, their widespread deployment on the battlefield still faces numerous formidable obstacles and inherent limitations. One of the most significant challenges stems from the substantial energy requirements needed to operate these high-powered systems effectively. The demand for a considerable amount of electrical power, combined with the necessity for robust cooling mechanisms, presents complex engineering and logistical hurdles for integration onto various military platforms.
Furthermore, the research and development (R&D) of DEWs remains a profoundly costly endeavor, demanding significant financial investment and extended timelines for maturation. Beyond the initial R&D, the practical applicability of several DEW types remains uncertain, often contingent on specific operational circumstances and environmental conditions. This uncertainty necessitates extensive testing and refinement before these systems can be reliably integrated into diverse combat scenarios, adding to the overall cost and complexity.
Laser beams, a prominent form of DEW, are particularly susceptible to environmental factors that can attenuate their power and reduce their effectiveness. Water vapor, dust, fog, and smoke in the atmosphere can significantly degrade beam quality. A critical phenomenon known as “blooming” occurs at energy densities of roughly one megajoule per cubic centimeter, where laser beams begin to produce plasma breakdown in the atmosphere. This action causes the laser to defocus and scatter energy into the surrounding air, with greater intensity in adverse atmospheric conditions.
Most DEWs also suffer from a limited effective range, where their power and destructive capabilities diminish significantly as the distance between the target and the weapon increases. This inherent characteristic means that while highly effective at closer ranges, their utility may be constrained in engagements requiring extreme long-range interception. Moreover, DEWs are not immune to countermeasures; utilizing reflective materials or other defensive strategies can mitigate their effectiveness, requiring continuous innovation in beam propagation and target engagement.
Beyond operational and technical constraints, the medical implications of exposure to these weapons remain an important issue due to a persistent lack of transparent and sufficient testing. Initial volunteer military testing revealed that such weapons can cause blisters and skin burns, alongside chronic agony. Electromagnetic waves, for instance, can penetrate beyond the dermal layer, leading to skin burns and dermal damage. The broader ethical and humanitarian considerations surrounding these effects also contribute to the complex landscape of DEW development and deployment, alongside the concern that the deployment of DEWs by one government could spark an arms competition among other countries, leading to increased international tensions.

11. **US Navy’s Advancements: Shipboard Laser Systems**The United States Navy is at the forefront of integrating directed energy weapons into its formidable fleet, recognizing their critical role in enhancing shipboard defense against evolving maritime and aerial threats. In a significant step, Lockheed Martin delivered the High Energy Laser with Integrated Optical-Dazzler and Surveillance (HELIOS), a 60+ kW-class laser system, to the U.S. Navy. This advanced system was successfully mounted on the Arleigh Burke-class destroyer USS Preble (DDG-88), marking a tangible progression in naval DEW capabilities and demonstrating the feasibility of integrating high-power lasers onto existing platforms.
Building on these successes, the US Navy has embarked on an ambitious $29.9-million project named SONGBOW, aimed at developing one of the world’s most powerful shipboard laser weapons. The core objective of SONGBOW is to effectively neutralize complex threats, including drone swarms, cruise missiles, and even hypersonic glide vehicles, at the speed of light. This initiative signifies a strategic leap over existing shipboard capabilities, focusing on delivering unprecedented defensive precision and responsiveness to naval assets.
At the heart of the SONGBOW system is a 400-kilowatt laser, engineered by combining multiple 50-kilowatt emitters into a single, precision-guided beam. This modular approach allows for scalable power levels without compromising beam quality, even during extended engagements, ensuring sustained effectiveness in dynamic combat scenarios. Coherent Aerospace & Defense is leading the build under a cost-plus-fixed-fee contract from the Office of Naval Research, with an initial development phase spanning 20 months, with options for extension into 2027.
Internally, the SONGBOW relies on pulsed fiber laser modules supported by a highly precise beam-control system to ensure accurate targeting. While its primary function is kinetic defense, the laser is also being shaped to support secondary roles, such as remote sensing and battlefield illumination. This multi-functional design enhances its utility, providing intelligence-gathering and situational awareness capabilities in addition to its defensive prowess.
The strategic vision for SONGBOW extends beyond its naval role, with the system being designed for potential deployment on land-based platforms. This reflects the Navy’s broader push to extend directed-energy capabilities across different mission environments, fostering interoperability and maximizing defensive coverage.

Summary: The United States Navy (USN) is the maritime service branch of the United States Department of Defense. It is the world’s most powerful navy with the largest displacement, at 4.5 million tons in 2021. It has the world’s largest aircraft carrier fleet, with eleven in service, one undergoing trials, two new carriers under construction, and six other carriers planned as of 2024. With 336,978 personnel on active duty and 101,583 in the Ready Reserve, the U.S. Navy is the third largest of the United States military service branches in terms of personnel. It has 299 deployable combat vessels and about 4,012 operational aircraft as of 18 July 2023. The U.S. Navy is one of six armed forces of the United States and one of eight uniformed services of the United States.
The United States Navy traces its origins to the Continental Navy, which was established during the American Revolutionary War and was effectively disbanded as a separate entity shortly thereafter. After suffering significant loss of goods and personnel at the hands of the Barbary pirates from Algiers, the United States Congress passed the Naval Act of 1794 for the construction of six heavy frigates, the first ships of the Navy. The United States Navy played a major role in the American Civil War by blockading the Confederacy and seizing control of its rivers. It played the central role in the World War II defeat of Imperial Japan. The United States Navy emerged from World War II as the most powerful navy in the world. The modern United States Navy maintains a sizable global presence, deploying in strength in such areas as the Western Pacific, the Mediterranean, and the Indian Ocean. It is a blue-water navy with the ability to project force onto the littoral regions of the world, engage in forward deployments during peacetime and rapidly respond to regional crises, making it a frequent actor in American foreign and military policy.
The United States Navy is part of the Department of the Navy, alongside the United States Marine Corps, which is its coequal sister service. The Department of the Navy is headed by the civilian secretary of the Navy. The Department of the Navy is itself a military department of the Department of Defense, which is headed by the secretary of defense. The chief of naval operations (CNO) is the most senior Navy officer serving in the Department of the Navy.

12. **US Air Force’s Laser Initiatives: Aerial Platforms**The United States Air Force is actively exploring and advancing the integration of directed energy weapons into its aerial platforms, aiming to leverage the unique advantages of laser technology for airborne missions. A notable development in this area is the Laser Advancements for Next-generation Compact Environments (LANCE) system, a high-energy laser weapon delivered to the U.S. Air Force by Lockheed Martin on July 12. This initiative underscores the military’s commitment to equipping air assets with cutting-edge defensive and potentially offensive capabilities.
LANCE is specifically designed as a pod weapon, indicating its modular nature and adaptability for installation on various types of aircraft. This podded configuration offers significant operational flexibility, allowing the laser system to be integrated or removed as mission requirements dictate, without necessitating permanent modifications to the aircraft itself. Such a design facilitates rapid deployment and enhances the multi-mission versatility of airframes within the Air Force inventory.
The development and integration of LANCE involve a collaborative effort among leading defense contractors. While Lockheed Martin provides the primary laser weapon, Boeing is responsible for constructing the pod that carries the LANCE system, ensuring its aerodynamic efficiency and structural integrity for airborne operations. Complementing this, Northrop Grumman supplies the sophisticated beam control system, a critical component that precisely directs the laser toward its intended target, ensuring accuracy and effectiveness during high-speed aerial engagements.
The deployment of such aerial laser weapons promises to significantly expand the reach and flexibility of directed energy capabilities. By operating from airborne platforms, these systems can offer extended range, rapid redeployment, and the ability to engage threats from advantageous positions, whether for defensive escort missions or precision targeting. This advancement marks a pivotal step in leveraging the unique environment of air superiority for the application of directed energy, further enhancing the Air Force’s operational effectiveness in contested airspace.

Summary: The Indian Air Force (IAF) (ISO: Bhāratīya Vāyu Senā) is the air arm of the Indian Armed Forces. Its primary mission is to secure Indian airspace and to conduct aerial warfare during armed conflicts. It was officially established on 8 October 1932 as an auxiliary air force of the British India which honoured India’s aviation service during World War II.
Since 1950, the IAF has been involved in four wars with neighbouring Pakistan. Other major operations undertaken by the IAF include Operation Vijay, Operation Meghdoot, Operation Cactus and Operation Poomalai. The IAF’s mission expands beyond engagement with hostile forces, with the IAF participating in United Nations peacekeeping missions.
The President of India holds the rank of Supreme Commander of the IAF. As of 1 January 2025, 135,000 personnel are in service with the Indian Air Force. The Chief of the Air Staff, an air chief marshal, is a four-star officer and is responsible for the bulk of operational command of the Air Force. There is never more than one serving ACM at any given time in the IAF. The rank of Marshal of the Air Force has been conferred by the President of India on one occasion in history, to Arjan Singh. On 26 January 2002, Singh became the first and so far, only five-star rank officer of the IAF.

13. **Russia and China: Rapid Escalation in DEW Development**Beyond the United States and its allies, major global powers such as Russia and China are relentlessly pursuing the induction of directed energy weapons, including high-energy lasers, into their respective militaries. This aggressive development highlights a global strategic race in advanced weaponry, with significant implications for international security and the balance of power. China, in particular, has openly showcased its ambitions, planning a grand military parade to unveil what it claims to be “the most powerful laser air defence system in the world.”
Russia has also made considerable strides, even claiming to be the “first country” to field laser weapons in combat. In 2018, President Putin unveiled the ‘Peresvet’ laser weapon, demonstrating Russia’s commitment to this technology. Furthermore, reports indicate that another advanced laser system, dubbed ‘Kalina,’ is currently under construction at a Russian space facility, reportedly designed with the specific objective of blinding enemy satellites, showcasing an advanced capability for space warfare and counter-space operations.
China, on its part, is also rapidly moving to field high-energy laser weapons across its forces. Chinese military experts have even claimed that the country’s J-20 fifth-generation stealth fighter, a cornerstone of its air superiority doctrine, could potentially be equipped with directed energy weapons. Such an integration would transform aerial combat capabilities, providing unprecedented tactical advantages in air-to-air engagements and ground attack roles through instantaneous, precise energy delivery.
Further evidence of China’s advancements includes an announcement by Chinese state television CCTV in early 2020 regarding their ongoing work on an airborne laser attack pod. This development parallels US efforts in aerial DEWs and suggests a focus on offensive as well as defensive applications. Additionally, Chinese defense companies have publicly displayed laser defense weapon systems, such as the LW-30, at demonstrations, indicating their readiness for deployment against various aerial targets, including drones and missiles. This rapid and often opaque development by both Russia and China creates a dynamic and challenging strategic landscape, particularly within the Indo-Pacific region, underscoring the urgent need for robust defensive capabilities and a clear understanding of these emerging threats.

Summary: Hong Kong is a special administrative region of the People’s Republic of China (PRC). Situated on China’s southern coast just south of Shenzhen, it consists of Hong Kong Island, Kowloon, and the New Territories. With 7.5 million residents in a 1,114-square-kilometre (430 sq mi) territory, Hong Kong is the fourth-most densely populated region in the world.
Hong Kong was established as a colony of the British Empire after the Qing dynasty ceded Hong Kong Island in 1841–1842 as a consequence of losing the First Opium War. The colony expanded to the Kowloon Peninsula in 1860 and was further extended when the United Kingdom obtained a 99-year lease of the New Territories in 1898. Hong Kong was occupied by Japan from 1941 to 1945 during World War II. The territory was handed over from the United Kingdom to China in 1997. Hong Kong maintains separate governing and economic systems from that of mainland China under the principle of one country, two systems.
Originally a sparsely populated area of farming and fishing villages, Hong Kong is now one of the world’s most significant financial centres and commercial ports. Hong Kong is the world’s third-ranked global financial centre behind New York City and London, ninth-largest exporter, and eighth-largest importer. Its currency, the Hong Kong dollar, is the ninth-most traded currency in the world. Home to the second-highest number of billionaires of any city in the world, Hong Kong has the second largest number of ultra high-net-worth individuals. The city has one of the highest per capita incomes in the world, while severe income inequality still exists among the population. Hong Kong is the city with the most skyscrapers in the world, even though its housing is consistently in high demand.
Hong Kong is a highly developed territory and has a Human Development Index (HDI) of 0.955, ranking eighth in the world and currently the only place in Asia to be in the top ten. The city has the highest life expectancy in the world, and a public transport usage exceeding 90 per cent.

14. **India’s Strategic Pursuit of Directed Energy Weapons**India views the development and deployment of directed energy weapons as a crucial imperative, especially in light of its evolving security environment and complex geopolitical relationships, notably with China. The nation’s Defence Research and Development Agency (DRDO) has taken a proactive stance, announcing intentions to build indigenous DEWs utilizing high-energy lasers and microwaves. This strategic push is an integral part of India’s broader commitment to ‘Atmanirbharta,’ or self-reliance, in defense technology and capabilities.
Currently, India’s DEW projects include the DRDO’s Counter IED 1 KW LASER system, designed for the remote disposal of unexploded bombs, mines, and improvised explosive devices (IEDs). With an effective range of 30-250 meters, this system provides a vital tool for ordnance disposal, enhancing the safety of military personnel and civilian populations in areas affected by conflict. It showcases a practical, field-deployable application of laser technology for immediate security challenges.
A more ambitious undertaking is the Kilo Ampere Linear Ejector (KALI), a particle accelerator developed jointly by DRDO and the Bhabha Atomic Research Center. This advanced DEW is conceptualized to fire intense electron pulses at incoming missiles and aircraft, with the objective of destroying their onboard electronic circuits. KALI represents India’s pursuit of high-power, non-kinetic intercept capabilities against sophisticated aerial threats, demonstrating a strategic focus on electronic warfare and system neutralization.
Furthermore, the Indian Army is slated to receive a 100-kilowatt, lightweight Laser Weapon System (LaWS) as part of the Directionally Unrestricted Ray-Gun Array (DURGA II) program. Currently at the concept stage, DURGA II is envisioned for integration with land, sea, and air-based platforms, emphasizing a multi-domain approach to DEW deployment. Additionally, the DRDO is developing infrared (IR) dazzlers to engage enemy planes and helicopters at a range of 10 km, alongside 25 kW LaWs designed to destroy missiles during their terminal phase at ranges of 5 to 7 km, offering close-in defense capabilities. The DRDO also plans to test a high-powered, truck-mounted 2 kW laser against targets 1 kilometer away, while the Laser Science & Technology Centre (LASTEC) has developed a 10 kW chemical oxygen-iodine laser and is working on 30-100 kW versions for vehicle mounting. LASTEC is also engaged in the Aditya project, focused on building gas dynamic high-power laser-based DEWs.
While India’s technological breakthroughs in directed-energy weapons are acknowledged to be in their infancy and currently lag behind the more powerful systems of the United States, Russia, and China, these sustained efforts underscore a determined strategic shift. The escalating security dynamics in the Indo-Pacific and beyond necessitate such investment. DEWs are anticipated to play a significant role in determining the outcome of future conflicts, offering a critical preventive capacity against hostile missiles and unmanned aerial vehicles, thereby strengthening the Indian armed forces’ defense posture and ensuring national security in an increasingly complex global environment.
Military equipment: Thermonuclear weapon

Summary: A thermonuclear weapon, fusion weapon or hydrogen bomb (H-bomb) is a second-generation nuclear weapon, utilizing nuclear fusion. The most destructive weapons ever created, their yields typically exceed first-generation nuclear weapons by twenty times, with far lower mass and volume requirements. Characteristics of fusion reactions can make possible the use of non-fissile depleted uranium as the weapon’s main fuel, thus allowing more efficient use of scarce fissile material. Its multi-stage design is distinct from the usage of fusion in simpler boosted fission weapons. The first full-scale thermonuclear test (Ivy Mike) was carried out by the United States in 1952, and the concept has since been employed by at least the five NPT-recognized nuclear-weapon states: the United States, Russia, the United Kingdom, China, and France.
The design of all thermonuclear weapons is believed to be the Teller–Ulam configuration. This relies on radiation implosion, in which X-rays from detonation of the primary stage, a fission bomb, are channelled to compress a separate fusion secondary stage containing thermonuclear fuel, primarily lithium-6 deuteride. During detonation, neutrons convert lithium-6 to helium-4 plus tritium. The heavy isotopes of hydrogen, deuterium and tritium, then undergo a reaction that releases energy and neutrons. For this reason, thermonuclear weapons are often colloquially called hydrogen bombs or H-bombs.
Additionally, most weapons use a natural or depleted uranium tamper and case. This undergoes fast fission from fast fusion neutrons and is the main contribution to the total yield and radioactive fission product fallout.
Thermonuclear weapons were thought possible since 1941 and received basic research during the Manhattan Project. The first Soviet nuclear test triggered an all-out pursuit of a thermonuclear weapon in the US, despite initial opposition by many former Manhattan Project scientists. The Teller-Ulam configuration, named for its chief contributors, Edward Teller and Stanisław Ulam, was outlined in 1951, with contribution from John von Neumann. Operation Greenhouse investigated thermonuclear reactions before the full-scale Mike test.
Multi-stage devices were later developed and tested, largely independently, by the Soviet Union (1955), the United Kingdom (1957), China (1966), and France (1968). There is not enough public information to determine whether India, Israel, or North Korea possess multi-stage weapons. Pakistan is not considered to have developed them. After the 1991 collapse of the Soviet Union, Ukraine, Belarus, and Kazakhstan became the first and only countries to relinquish their thermonuclear weapons, although these had never left the operational control of Russian forces. Following the 1996 Comprehensive Nuclear-Test-Ban Treaty, most countries with thermonuclear weapons maintain their stockpiles and expertise using computer simulations, hydrodynamic testing, warhead surveillance, and inertial confinement fusion experiments.
Thermonuclear weapons are the only artificial source of explosions above one megaton TNT. The Tsar Bomba was the most powerful bomb ever detonated at 50 megatons TNT. As they are the most efficient design for yields above 50 kilotons of TNT (210 TJ), and with decreased relevance of tactical nuclear weapons, virtually all nuclear weapons deployed by the five recognized nuclear-weapons states today are thermonuclear. Their development dominated the Cold War’s nuclear arms race. Their destructiveness and ability to miniaturize high yields, such as in MIRV warheads, defines nuclear deterrence and mutual assured destruction. Extensions of thermonuclear weapon design include clean bombs with marginal fallout and neutron bombs with enhanced penetrating radiation. Nonetheless, most thermonuclear weapons designed, including all current US and UK nuclear warheads, derive most of their energy from fast fission, causing high fallout.
