My Article was published in the Life of Soldier Journal on April 25.

 

Hindustan Aeronautics Limited (HAL) has been in the spotlight for its recent achievements and challenges. The company has secured significant defence contracts, including a deal for LCA Tejas Mk1A fighter jets and a substantial agreement for Indigenous helicopters. HAL has also made strides in the Advanced Medium Combat Aircraft (AMCA) program, enhancing India’s aerospace capabilities. However, the company has faced scrutiny over production delays and concerns raised by the Indian Air Force regarding aircraft availability.

 

The Indian Air Force (IAF) has been a stalwart in the pursuit of indigenisation, a strategic move to reduce dependence on foreign suppliers and bolster national security. Key initiatives include the induction of HAL’s Tejas fighter jets, the Advanced Medium Combat Aircraft (AMCA) development, and the procurement of indigenous helicopters like the Light Combat Helicopter (LCH) Prachand. The IAF’s investments in indigenous UAVs, radars, and advanced weapon systems are a testament to its commitment to enhancing self-reliance. While challenges persist, a collaborative effort between the IAF, HAL, and private industry is pivotal in realising India’s vision of a robust and self-sufficient aerospace defence ecosystem.

 

India’s journey towards self-reliance in defence aviation has been long and complex, with the Indian Air Force (IAF) and Hindustan Aeronautics Limited (HAL) playing pivotal roles. Achievements, setbacks, and continued aspirations for indigenisation have marked the relationship between these two institutions. While HAL has been the backbone of India’s military aviation industry, the IAF has often raised concerns over delays, quality issues, and technological limitations. This article explores the evolution of this partnership, its challenges, and the way forward for India’s indigenous aerospace ambitions.

 

HAL was founded in 1940 as Hindustan Aircraft Limited and nationalised in 1964. Over the decades, it has been responsible for manufacturing, assembling, and maintaining various aircraft for the IAF, ranging from early license-built fighters to the Indigenous Tejas fighter jet. HAL has played a crucial role in India’s defence self-sufficiency by working on aircraft like the HF-24 Marut, Dhruv helicopters, and, more recently, the LCA Tejas and AMCA (Advanced Medium Combat Aircraft) projects.

 

The Indian Air Force (IAF) has always been a strong advocate for the development of indigenous defence production capability, a key result area for the IAF. The IAF has played a crucial role in creating an aerospace ecosystem in India, operating indigenously built aircraft and those built by HAL under licence production, which has given impetus to the indigenous industry in the past. The IAF’s support for indigenised inductions and projects is evident in its involvement in the following initiatives:

 

    • Induction of LCA (IOC, FOC, Mk I and Mk 1A) and support to LCA Mk II and AMCA.
    • Induction of Ajeet and HF-24 Marut ac in the past.
    • Induction of AEW&C ac and support to indigenous AWACS project.
    • Induction of indigenous helicopter ALH and support to LCH.
    • Induction of Trainer aircraft (Kiran Mk I and Mk II, HT-2, HPT & HTT-40 aircraft).
    • Support to the replacement of Avro aircraft through the make-in-India route.
    • Integration and operationalisation of Astra Air to Air Missile and Brahmos Air to surface missiles.
    • Integration of weapons like the New Generation Anti-tank Missile, Smart anti-airfield weapons, new generation anti-radiation missiles, and Glide bombs.

 

IAF’s Dependence on HAL. HAL’s contribution to the IAF has been significant, with aircraft like the MiG-21, Jaguar, Su-30MKI, and Hawk trainers being produced or assembled under license. However, the IAF has sometimes expressed concerns over HAL’s efficiency, particularly regarding production delays, maintenance backlogs, and a lack of cutting-edge technology. The slow pace of the LCA Tejas program and delays in upgrades of existing fleets have strained the relationship between the two.

 

Success Stories: HAL’s Contributions to IAF. Hindustan Aeronautics Limited (HAL) has been the cornerstone of India’s military aviation industry, supporting the Indian Air Force (IAF) for over eight decades. From license-producing early-generation fighters to developing Indigenous aircraft and helicopters, HAL has made significant strides in enhancing India’s self-reliance in defence aviation. Despite facing challenges, its contributions have been instrumental in shaping the IAF’s combat capabilities, a fact that we, as a nation, should deeply appreciate and respect.

 

HAL’s association with the IAF began with the production of British-origin Hawker Tempest aircraft in the 1940s. However, its true contribution to India’s air power started in the 1960s when it began license manufacturing the MiG-21 under Soviet collaboration. The MiG-21 became the backbone of the IAF for decades, with HAL producing over 600 aircraft. These fighters played a crucial role in conflicts like the 1971 Indo-Pak War and the Kargil War (1999). During the same period, HAL made its first attempt at designing an indigenous fighter—the HF-24 Marut, India’s first home-grown jet.  The lessons learned from this project laid the foundation for future indigenous aircraft programs. In the 1980s, HAL was critical in assembling and maintaining the SEPECAT Jaguar, a deep-strike fighter that remains a vital part of the IAF’s fleet. HAL later upgraded the Jaguar under the DARIN modernisation programs, equipping it with modern avionics and weaponry.

 

Su-30MKI: The Backbone of the IAF. One of HAL’s biggest success stories has been the license production of the Su-30MKI, India’s premier air superiority fighter. Since the early 2000s, HAL has built over 270 Su-30MKIs, making them the most numerous and capable aircraft in the IAF’s fleet. The company has also integrated indigenous systems into the Su-30MKI, such as BrahMos-A supersonic cruise missiles, further enhancing its strike capability.

 

LCA Tejas: India’s Indigenous Fighter Jet. The Light Combat Aircraft (LCA) Tejas is a landmark achievement for HAL and India’s defence industry. After initial delays, Tejas was inducted into the IAF. The improved Tejas Mk1A, featuring advanced radar, electronic warfare systems, and upgraded weapons, is expected to be inducted soon. Developing the Tejas Mk2, Twin-Engine Deck-Based Fighter (TEDBF), and fifth-generation AMCA showcases HAL’s progress toward advanced indigenous fighters.

 

Indigenous Helicopters: ALH Dhruv, LCH, and LUH. HAL strengthened the IAF’s rotary-wing capabilities with the Advanced Light Helicopter (ALH) Dhruv and its armed variant, Rudra. Another significant achievement is the Light Combat Helicopter (LCH) Prachand, designed for high-altitude operations in Ladakh and Siachen. HAL has also developed the Light Utility Helicopter (LUH) to replace ageing Cheetah and Chetak helicopters.

 

The Challenges

Despite HAL’s significant contributions to the Indian Air Force (IAF), several challenges continue to hinder their partnership, affecting operational readiness and modernisation efforts. One of the most pressing concerns is production delays, which have consistently impacted the induction of critical platforms. The slow pace of Tejas fighter production, delays in the upgrade program, and prolonged timelines for overhauls have led to capability gaps in the IAF. These setbacks have forced the IAF to rely on older aircraft, delaying modernisation. Another significant issue is quality control, with HAL facing criticism over the reliability of its manufactured and overhauled aircraft. The users have raised concerns about technical faults, maintenance inefficiencies, and accidents of some HAL-built platforms, leading to questions about overall workmanship and durability. HAL’s slow adoption of new technologies has also affected India’s ability to match global defence standards. Unlike leading aerospace firms, HAL struggles with R&D investments and innovation, leading to dependence on foreign suppliers for engines, avionics, and weapon systems.

 

The Way Ahead for HAL: Strengthening India’s Aerospace Future

It is time for HAL to leave behind past setbacks, tackle challenges, and move on with renewed determination. Hindustan Aeronautics Limited (HAL) must adopt a multi-pronged approach. Enhancing innovation, investing in R&D, fostering collaborations, and streamlining production can make it a stronger, future-ready HAL that is ready to drive India’s aerospace future, ensuring self-reliance and global competitiveness in defence manufacturing.

Enhancing Production Efficiency. HAL needs to streamline its manufacturing and assembly processes to reduce production delays. Modern automation, digital manufacturing, and lean production techniques can significantly reduce production time. Strengthening supply chains and increasing outsourcing to private-sector firms will also boost production efficiency.

Strengthening Quality Control. HAL must revamp its quality assurance mechanisms to address users’ concerns. A stringent inspection and testing framework at every stage of aircraft manufacturing and overhaul processes will ensure higher reliability and safety. Implementing global best practices and learning from established aerospace giants can help improve production standards.

Investing in Advanced R&D. One of HAL’s most significant drawbacks is its slow pace of technological innovation. To bridge this gap, HAL must increase investments in indigenous research and development (R&D), particularly in engines, avionics, stealth technology, and composite materials. Stronger collaboration with DRDO, ISRO, and academic institutions can accelerate innovation in next-generation aircraft and air combat systems.

Strengthening the Private Sector Collaboration. Public-private partnerships will be key to HAL’s future success. Companies like Tata, L&T, and Mahindra Defence are emerging as strong players in the defence aviation sector. HAL must leverage these partnerships for joint development, co-production, and component outsourcing, improving efficiency and reducing costs.

Reforming Organisational and Management Structure. HAL must transition from a bureaucratic public-sector enterprise to a more agile, corporate-driven entity to compete globally. Introducing performance-based accountability, faster decision-making mechanisms, and strategic planning frameworks will enable HAL to operate more efficiently.

Commitment to Future Programs. HAL must stay committed to high-priority projects like the Tejas Mk II, Advanced Medium Combat Aircraft (AMCA), and Twin Engine Deck-Based Fighter (TEDBF). These programs will define the future of Indian military aviation and ensure long-term self-reliance.

Focusing on Export Potential. HAL must actively market its aircraft, helicopters, and UAVs to international customers. The Tejas LCA, LCH Prachand, and Dhruv helicopters have attracted global interest. Expanding exports will generate revenue and establish India as a key defence exporter.

 

Conclusion

HAL stands at a crucial juncture and must evolve into a world-class defence aerospace manufacturer. By focusing on efficiency, innovation, private sector collaboration, and exports, HAL can not only strengthen the IAF but also contribute significantly to India’s goal of self-reliance in defence manufacturing (Atmanirbhar Bharat).

632: 5G RACE BETWEEN THE DRAGON AND THE EAGLE: POTENTIAL TO ENHANCE AERIAL WARFARE

 

My Article Published on the EurasianTimes Website on 30 Mar 25.

 

Beginning of Mar 25, at the Mobile World Congress (MWC) in Barcelona, Nokia revealed that US defence and aerospace manufacturer Lockheed has deployed Nokia’s 5G solutions into its Hybrid Base Station. According to its website, Lockheed’s HBS is a unified network solution that provides communications, Edge processing, and advanced network capabilities for interoperable, resilient, and secure connectivity and data flow across all domains. Nokia added that its military-grade 5G technology makes it possible to “integrate commercial 5G connections with military communications systems to provide decisive information for national defence,” highlighting the importance of interoperability.

 

Earlier this year, China claimed to have introduced what it describes as the world’s first mobile 5G base station for military purposes. According to a South China Morning Post report, it was developed in partnership with China Mobile Communications Group and the Chinese People’s Liberation Army (PLA). The reports highlighted that the 5G mobile base station delivers high-speed, low-latency, and secure data services, supporting up to 10,000 users within a 3km radius. The system maintains a consistent total throughput of 10 gigabits per second with latency under 15 milliseconds. The report also stated that this new 5G base station paves the way for the extensive deployment of intelligent war machines. China is currently constructing what it claims to be the world’s most significant unmanned military force, featuring advanced yet cost-effective drones, robotic dogs, and other autonomous combat platforms that could eventually outnumber human soldiers.

 

Effective communication is essential in military aviation, where split-second decisions can determine a mission’s success or a personnel’s safety. The advent of fifth-generation wireless technology (5G) and advanced communication networks promises to revolutionise this field. With unparalleled speed, low latency, and extensive connectivity, 5G has transformative potential for real-time data sharing among aircraft, command centres, and other platforms. It enhances real-time communications in military aviation, strengthens network-centric warfare for a more integrated air force, and introduces security risks that must be addressed to protect operations. By examining these factors, we can recognise the significant implications of advanced communication technologies for modern military aviation.

 

Understanding 5G Technology. 5G, the fifth generation of wireless communication technology, is characterised by its high speed, low latency, and capacity to connect many devices simultaneously. These attributes make it a game-changer for military aviation, where timely and reliable communication is critical. Unlike its predecessors, 5G operates on higher frequency bands, such as millimeter waves, providing wider bandwidths for faster data transmission. It also employs techniques like beam forming, directing signals to specific devices rather than broadcasting omnidirectionally, to optimise signal strength and reduce interference.

 

Military Aviation: Possibilities

In military aviation, real-time data sharing involves the seamless exchange of information between aircraft, command centers, unmanned aerial vehicles (UAVs), and other platforms. 5 G’s speed often exceeds 1 Gbps. Its latency, reduced to as low as 1 millisecond, enables near-instantaneous communication, a stark improvement over 4G’s 20-30 millisecond latency.

Types of Data.  Real-time data is crucial in military and defence applications, enhancing situational awareness and operational efficiency. Sensor data from radar, infrared, and other detection systems provide critical intelligence on enemy positions and movements. For instance, a fighter jet detecting a hostile target can instantly transmit its coordinates to allied forces, improving response time. Video feeds, including HD or 4K footage from UAVs or onboard cameras, offer live intelligence, with 5G ensuring seamless transmission to command centers. Telemetry data tracks aircraft speed, altitude, fuel levels, and system health, enabling proactive maintenance and reducing downtime. Communication data, including voice and text transmissions, ensures seamless coordination between pilots, ground crews, and commanders, facilitating synchronised operations. These data types support real-time decision-making, enhancing battlefield effectiveness, reducing risks, and optimising mission success rates. Integrating AI and advanced networks further strengthens these capabilities, making modern military operations more responsive and precise.

Enhancing Data Sharing Across Platforms. In combat scenarios, aircraft must exchange vast amounts of data, radar signatures, sensor readings, high-definition video feeds, and tactical updates with command centers and allied units. Consider a multi-aircraft operation targeting enemy defences: each fighter jet must instantly share its position, target data, and threat assessments. For instance, a reconnaissance plane detecting an enemy convoy could stream live video to a command center, relaying precise coordinates to strike aircraft within moments. This speed enhances decision-making, enabling commanders to adapt strategies dynamically. Moreover, 5G’s low latency is a game-changer for time-sensitive applications. Even a half-second delay could be fatal during air-to-air engagements, where pilots rely on real-time radar and missile lock data. By slashing latency to 1 ms, 5G ensures data arrives when needed, improving coordination and precision.

Integration with Unmanned Systems. Unmanned aerial vehicles (UAVs) and drones are increasingly vital to military operations and performing reconnaissance, strikes, and electronic warfare. These systems depend on robust communication links to receive commands and transmit data. 5G’s high capacity and responsiveness enhance this connectivity. For example, a drone swarm conducting surveillance over hostile territory could send high-resolution imagery back to a command center while receiving real-time updated flight instructions. This capability supports more autonomous and complex UAV missions, such as coordinated attacks or perimeter defence, by maintaining a constant, reliable link. Additionally, 5G’s massive device connectivity allows numerous sensors and platforms to be integrated. A single operation might involve dozens of drones, manned aircraft, and ground stations, all sharing data through a unified network. This scalability ensures the communication infrastructure can keep pace as unmanned systems proliferate, fostering a more versatile and responsive air force.

Network-Centric Joint Warfare. Network-centric warfare (NCW) redefines military operations by linking all elements, aircraft, ground forces, naval units, and command centers into a cohesive information-sharing network. The goal is to achieve a decisive advantage through enhanced situational awareness, coordination, and speed. In aviation, NCW transforms isolated aircraft into nodes within a broader system, amplifying their effectiveness through collective intelligence. With 5G, NCW reaches new heights. Its high-speed, low-latency network enables seamless data exchange across platforms, creating a more integrated air force. Imagine a scenario where a reconnaissance drone identifies a mobile missile launcher. Within seconds, 5G transmits this intelligence to a nearby fighter jet, which adjusts its flight path while informing ground-based air defences and a command center. The jet engages the target, and the updated status is shared network-wide, allowing other units to reposition accordingly. This rapid, synchronised response exemplifies how 5G enhances operational tempo and effectiveness.

Enhancing Situational Awareness.  Modern combat aircraft, including fifth- and sixth-generation fighters, rely heavily on seamless communication with command centers, reconnaissance drones, and other allied aircraft. The ability to transmit and receive data in real time enhances situational awareness, allowing pilots to react swiftly to evolving threats.

Optimising Command and Control. Military command centers depend on real-time data feeds to make strategic decisions. 5G networks enable instantaneous transmission of mission-critical information, including radar feeds, target tracking, and intelligence updates. This increased speed and reliability minimises decision-making delays, ensuring that commanders can deploy assets more efficiently and respond dynamically to threats.

AI and Big Data Integration. Advanced communication networks empower artificial intelligence (AI) systems to analyse vast battlefield data in real time. AI-driven analytics can provide predictive insights on enemy movements, optimise flight paths, and suggest strategic manoeuvres to pilots. Fusing AI with 5G networks creates a more innovative, adaptive military force capable of making split-second decisions based on real-time intelligence. This integration allows for the efficient processing of large volumes of data, enabling the military to make informed decisions and respond effectively to changing situations.

 

Security Risks

Integrating 5G into military aviation offers enhanced communication, real-time data sharing, and improved battlefield awareness. However, it also introduces significant security risks that could compromise mission success. As military systems increasingly rely on wireless, software-driven networks, the attack surface expands, creating new vulnerabilities.

One primary concern is jamming and interference, whereby adversaries employ electronic warfare techniques to disrupt 5G signals, which could sever critical communication links. Cyber attacks pose another serious threat; hackers might manipulate data transmissions, injecting false coordinates into navigation systems, potentially leading to disastrous consequences such as mission failure or friendly fire. Espionage is also a pressing issue, as adversaries could intercept sensitive transmissions, including radar data and flight plans, thereby exposing strategic operations. Furthermore, vulnerabilities in the supply chain emerge due to reliance on commercial 5G infrastructure.

Many private firms involved in 5G deployment may inadvertently introduce security loopholes, whether intentionally or not, granting hostile entities backdoor access. The sheer speed of 5G exacerbates these risks, allowing adversaries to launch large-scale cyber attacks more swiftly than traditional defence mechanisms can react. Additionally, the heavy dependence on virtualisation and software-defined networking introduces software-based vulnerabilities, which, if left unpatched, could be exploited by sophisticated attackers.

EW adds another layer of complexity. Adversaries might target 5G’s millimeter-wave frequencies, which, while offering high bandwidth, are susceptible to interference in contested environments. A successful jamming operation could isolate aircraft from command, crippling NCW’s effectiveness.

Threats to Military Aviation. These risks have dire implications in aviation. A compromised 5G network could disrupt UAV control, causing drones to crash or attack unintended targets. Interrupted communications might allow enemies to anticipate and counter manoeuvres during a coordinated strike. Moreover, reliance on commercial networks shared in 5G deployments raises concerns about espionage, especially if foreign entities dominate the supply chain. For instance, debates over certain manufacturers’ involvement in 5G infrastructure highlight fears of embedded vulnerabilities accessible to rival nations.

 

Mitigation Strategies.

To address the security risks associated with 5G in military aviation, robust defence mechanisms must be established. Encryption is vital, ensuring that intercepted communications remain indecipherable to adversaries—end-to-end encryption safeguards sensitive data, such as radar feeds and flight plans, from exploitation. Authentication protocols further bolster security by requiring multi-factor authentication to verify user and device identities, thereby preventing unauthorised access. Intrusion detection systems play a crucial role by continuously monitoring network traffic for anomalies, enabling rapid responses to cyber threats before they cause harm. Furthermore, redundancy is essential—backup communication channels, such as satellite links, provide fail-safes during 5G network disruption due to jamming or cyber attacks. Developing dedicated, military-specific 5G networks, distinct from commercial infrastructure, further enhances security by minimising exposure to supply chain risks and potential backdoors. Regular security audits and penetration testing assist in identifying vulnerabilities before adversaries can exploit them. Collaborating with the private sector can also strengthen the security of commercial components used in military applications. Lastly, training personnel to recognise cyber threats and respond effectively ensures that human factors do not become vulnerabilities in cyber security. The military can mitigate 5G-related risks while harnessing its advantages by adopting a comprehensive, multi-layered defence strategy.

 

Conclusion

The 5G race between China and the United States is more than just a contest for technological supremacy; it is a battle that could redefine the future of aerial warfare. As both nations invest heavily in next-generation networks, integrating 5G into military aviation will enable faster data transmission, enhanced artificial intelligence, and real-time battlefield awareness. This technology has the potential to revolutionise drone warfare, enable seamless coordination between manned and unmanned systems, and improve electronic warfare capabilities. However, the competition is not solely about innovation but security and strategic dominance. The United States remains wary of China’s 5G infrastructure, citing risks of espionage and cyber vulnerabilities, while China continues to push its indigenous advancements to reduce dependence on Western technology. The outcome of this race will not only shape military strategies but also influence global alliances, trade policies, and the future of digital warfare. As the dragon and the eagle vie for control, nations aligning with either power must carefully navigate the geopolitical implications of their technological choices. Ultimately, the side that harnesses 5G most effectively for aerial combat may gain a decisive edge in future conflicts, setting the stage for a new era of warfare.

629: LEONIDAS BY EPIRUS: STAR TREK STYLE SHIELD OF DIRECTED ENERGY WEAPON

 

My Article published on the EurasianTimes Website on 28 Mar 25.

 

The most recent and significant news, announced in March 2025, is that Epirus Inc., a defence technology start-up based in Torrance, California, has unveiled the Leonidas system, a high-power microwave (HPM) weapon designed to neutralise unmanned aerial vehicle (UAV) swarms. This innovative system emits electromagnetic pulses to disable drones individually or across a broad area, offering a scalable solution to counter drone threats. The Leonidas system has been likened to a “Star Trek-style” shield due to its ability to disable or destroy drones within seconds. Beyond its counter-drone capabilities, the Leonidas system’s versatility allows it to disable electronics in ground vehicles and sea vessels, demonstrating its potential across various defences.

In the rapidly evolving landscape of modern warfare, unmanned aerial systems (UAS) have emerged as a significant and multifaceted threat. Due to their high operational costs and limited ammunition capacity, traditional defence mechanisms, such as missiles or anti-aircraft guns, struggle to keep pace with these agile, numerous, and often low-cost adversaries. The Leonidas system addresses these challenges through directed energy technology, allowing for rapid, reusable, and cost-effective simultaneous engagement of multiple threats.

Named after the legendary Spartan king who famously stood against overwhelming odds at Thermopylae, the Leonidas system embodies a bold and forward-thinking approach to defence. Leveraging cutting-edge HPM technology, it offers a non-kinetic alternative to conventional systems, addressing one of the most pressing challenges of the 21st century.

 

High-Power Microwave Technology. HPM systems generate electromagnetic waves ranging from 300 MHz to 300 GHz. Unlike the microwaves used in household ovens to heat food by exciting water molecules, HPM delivers intense bursts of energy capable of inducing currents in electronic circuits. When directed at a target, these microwaves can disrupt or permanently damage sensitive components, rendering devices like drones inoperable. HPM’s ability to affect a broader area rather than a single pinpoint sets it apart from other directed energy technologies, such as lasers. This makes it particularly effective against multiple targets or swarms, a critical advantage in scenarios where dozens or hundreds of drones might be deployed simultaneously. Historically, HPM systems relied on vacuum tube technology, which was bulky, fragile, and maintenance-intensive. However, recent advancements in solid-state electronics have revolutionised the field. Solid-state HPM systems, like the one powering Leonidas, use semiconductor devices to generate microwaves, offering greater durability, efficiency, and compactness, attributes that make the technology viable for real-world deployment.

 

The Leonidas System.

The Leonidas system is a pinnacle of Epirus’s expertise in solid-state HPM technology. While proprietary details remain closely guarded, the key aspects of its design and functionality can be based on the general principles of HPM and publicly available information.

 At its core, the system likely features an array of solid-state amplifiers that generate and amplify microwave signals. These signals are then emitted through a steerable antenna, allowing operators to direct the HPM beam toward specific targets or areas. The power output of the Leonidas system would be a critical factor in its effectiveness. Although exact specifications are not disclosed, HPM systems typically produce peak powers ranging from hundreds of kilowatts to several megawatts. This energy is sufficient to disable the electronics of drones within a specific range, which depends on factors such as power levels, frequency, and atmospheric conditions. Unlike lasers, which maintain a tight beam over long distances, HPM waves experience divergence and can be attenuated by moisture or particles in the air, potentially limiting their range. However, this constraint is less significant for counter-drone applications where threats are often within a few kilometers.

Advanced targeting and control systems are integral to the Leonidas platform. These likely include radar or optical sensors to detect and track drones, paired with sophisticated software that prioritises targets and adjusts the beam’s intensity and direction. The result is a highly responsive system capable of engaging fast-moving threats with near-instantaneous effect, as HPM travels at the speed of light. These systems also enable the Leonidas to distinguish between friendly and hostile drones, reducing the risk of friendly fire and enhancing its effectiveness in complex operational environments.

Epirus has developed fixed and mobile versions of the Leonidas system, enhancing its versatility. Stationary installations might protect critical infrastructure, while vehicle-mounted units could support troops in the field, offering a flexible defence against dynamic threats.

 

Applications

The primary mission of the Leonidas system is to counter drone threats, a capability that addresses a growing concern in military and civilian contexts. The Leonidas system excels in such scenarios, using its wide-area HPM effects to disable multiple drones with a single burst. This makes it an ideal solution for protecting military installations, convoys, or naval vessels from both individual and coordinated drone attacks.

Beyond counter-drone operations, the Leonidas system holds promise for electronic warfare. Targeting enemy communication systems, radars, or other electronic equipment could degrade an adversary’s situational awareness or operational capabilities without firing a shot. Additionally, the technology might be adapted to disable vehicles or machinery reliant on electronic controls, though this could require higher power levels or closer proximity to the target.

Epirus has also hinted at broader applications, such as non-lethal uses for perimeter security or crowd control. In these scenarios, HPM could deter intrusions or disable unauthorised devices without causing permanent harm, offering a versatile tool for law enforcement or homeland security.

 

Advantages. 

The Leonidas system offers several compelling advantages over conventional kinetic defence systems, making it a game-changer in the fight against emerging threats.

    • Cost-Effectiveness. Engaging a target with HPM requires only electrical energy, a fraction of the cost of expending missiles or ammunition. This is particularly advantageous against low-cost drones, where using expensive munitions is economically unsustainable.
    • Precision and Control. Operators can tune the system to affect specific areas or targets, minimising collateral damage. Adjusting power output in real time allows it to respond to varying threat levels with tailored precision.
    • Scalability. From small consumer drones to larger military UAS, the Leonidas system can adapt its energy output to neutralise a wide range of targets, offering flexibility across different operational contexts.
    • Unlimited Magazine. Unlike guns or missile launchers with finite ammunition, the Leonidas system can operate continuously as long as it has power, making it ideal for prolonged engagements or swarm attacks.

 

Challenges

Despite its promise, the Leonidas system faces several technical and operational challenges that must be addressed for widespread adoption:-

    • Power Requirements. Generating high-power microwaves demands significant electrical energy. For mobile deployments, this necessitates robust power sources, such as large batteries or generators that could limit the system’s portability or require frequent recharging.
    • Range and Environmental Limitations. HPM’s effectiveness decreases with distance due to beam divergence and atmospheric absorption. Adverse weather conditions, such as rain or fog, could further reduce performance, potentially requiring multiple units for comprehensive coverage.
    • Integration with Existing Systems. Incorporating a novel technology like HPM into established defence frameworks involves significant hurdles. This includes adapting hardware, training personnel, and developing tactics to maximise its utility alongside traditional systems.
    • Unintended Disruptions. HPM’s broad-area effects could inadvertently interfere with friendly electronics, communication networks, or civilian infrastructure if not carefully managed. Robust targeting and safety protocols are essential to mitigate this risk.
    • Strategic Considerations. While primarily defensive, the ability to disable electronics at a distance raises questions about potential offensive applications or escalation in conflicts. International laws and treaties governing directed energy weapons may need to evolve to address these concerns and ensure responsible use.

 

Impact and Future Prospects

Epirus has successfully tested the Leonidas system, showcasing its ability to neutralise drone swarms with precision and speed. These demonstrations have attracted global attention from military and defence organisations, underscoring the system’s potential to fill a critical gap in countermeasures. Partnerships with defence contractors or government agencies signal growing confidence in HPM technology and its readiness for operational deployment.

Looking to the future, Epirus may enhance the Leonidas system with more significant power outputs to tackle more prominent or more resilient targets. Integration with complementary technologies, such as lasers, could create a multi-layered defence system, combining HPM’s wide-area effects with a laser’s pinpoint accuracy. Advances in artificial intelligence and machine learning could also enable autonomous operation, allowing the system to detect, prioritise, and engage threats in complex environments with minimal human intervention.

The broader implications of the Leonidas system extend beyond immediate defence needs. As directed-energy weapons gain traction, they could influence global military strategies, potentially sparking an arms race or prompting new regulatory frameworks. For now, its focus on countering drones positions it as a vital tool in an increasingly drone-dominated world.

 

Global DEW Projects

Directed energy weapons (DEWs) are advanced technologies that use focused energy, such as lasers or microwaves, to disable or destroy targets without physical projectiles. Numerous countries are researching and developing these weapons, each with unique projects and strategic goals.

United States. The US is a leader in DEW development. Besides Leonidas, the Department of Defence (DOD) and agencies like DARPA, the Air Force Research Laboratory, and the Naval Research Laboratory are researching DEWs to counter ballistic missiles and hypersonic cruise missiles. Notable projects include the High-Energy Laser Scaling Initiative (HELSI) and systems like HELIOS, with demonstrations successfully shooting down drones.

China. China is making rapid strides in DEW development, with a focus on high-energy lasers and microwave systems. State media and manufacturers have released images of handheld and vehicle-mounted laser systems, including the LW-30, a 30kW road-mobile high-energy laser (HEL) designed for unmanned aerial systems (UAS) and precision-guided weapons. Their efforts extend to counter space applications, with ground-based DEWs potentially targeting satellites, as highlighted in analyses.

Russia. Russia has been developing DEWs for decades, with the Peresvet laser weapon system entering experimental combat duty in 2018 and claimed operational use during the 2022 invasion of Ukraine. A more advanced version, “Zadira,” can incinerate targets up to three miles away within five seconds. Russia is also working on EMP cannons and microwave guns for anti-drone applications.

United Kingdom. The UK’s Ministry of Defence (MOD) is investing heavily in DEWs, with projects like DragonFire, a laser-directed energy weapon (LDEW) that achieved its first high-power firing against aerial targets in January 2024 at the Hebrides Range.  DragonFire, with a range classified but capable of hitting a £1 coin from a kilometer away, is expected to be deployable by 2027. Additionally, the Radio Frequency Directed Energy Weapon (RFDEW) is nearing service by 2026, focusing on countering unmanned systems.

France and Germany. France and Germany are key players in European DEW development, often through multinational collaborations. France is involved in projects like the TALOS-TWO, involving 21 partners across eight EU nations. Germany is focusing on integrating DEWs into defence platforms. These efforts aim for operational deployment by 2030, emphasising cost-effective counter-drone and missile defence systems.

India. India’s Defence Research and Development Organisation (DRDO) is actively pursuing DEWs, with projects like the Directionally Unrestricted Ray-Gun Array (DURGA II), a 100-kilowatt lightweight DEW at the concept stage, set for integration with land, sea, and air platforms. Other initiatives include the KALI particle accelerator and a 1KW laser weapon for counter-IED operations, with plans for 25-kW and 100-kW systems.

Israel. Israel is advancing the Iron Beam laser-based DEW, designed to complement its Iron Dome system. A contract signed in October 2024 for operational service within a year reflects its cost-effectiveness. The US has allocated $1.2 billion for Iron Beam procurement.

Iran and Turkey. They claim DEWs in active service, adding controversy to global assessments. Iran has announced developments in laser air defence systems, while Turkey claims the ALKA DEW was used in combat in Libya in 2019. However, specifics and verification are scarce, with claims often met with scepticism due to limited transparency.

South Korea, Japan, and Australia. South Korea and Japan have advanced technological capabilities, with South Korea developing laser-based systems for counter-drone applications, though less prominently than significant powers. Japan focuses more on nuclear and space technologies, with limited public DEW projects. Australia is investing in DEW technology, particularly for countering drones, with a $13 million deal with QinetiQ for a prototype defensive laser.

 

Conclusion

The Leonidas system by Epirus marks a transformative advancement in modern defence. It harnesses high-power microwave technology to address the escalating threat of drones and electronic-based hazards. Its non-kinetic approach offers a cost-effective, precise, and scalable solution that outperforms traditional systems in key areas, from countering swarms to enabling electronic warfare. While challenges such as power demands, environmental constraints, and integration remain, the system’s successful demonstrations and growing adoption signal its readiness to make a lasting impact.

The future of Directed Energy Weapons (DEWs) is promising, with advancements in laser, microwave, and particle beam technologies enhancing their effectiveness. These weapons offer rapid engagement, precision targeting, and cost efficiency, making them invaluable for missile defence, drone neutralisation, and electronic warfare. However, hurdles such as energy storage, environmental limitations, and legal-ethical concerns must be overcome. As nations invest in DEW research, their role in modern warfare will expand, shaping the next generation of defence capabilities.
