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.

627: INVOLVEMENT OF THE PRIVATE SECTOR IN INDIAN FIGHTER JET PRODUCTION

My Article published on the Chanakya Forum Website

on 24 Mar 25.

A recent Indian defence committee has recommended increasing private sector participation in military aircraft manufacturing to enhance the Indian Air Force’s capabilities. The committee, led by the defence ministry’s top bureaucrat, submitted its report to Defence Minister Rajnath Singh, who has directed that the recommendations be implemented promptly. The report emphasises the need for private companies to work alongside Defence Public Sector Undertakings (DPSUs) and the Defence Research and Development Organisation (DRDO) to achieve self-reliance in aerospace manufacturing. It suggests implementing short-, medium–, and long-term measures to expedite the production of Light Combat Aircraft (LCA) variants, including Mk-1, Mk-1A, and Mk-2, to address delays and strengthen the IAF’s operational readiness.

India’s aerospace and defence sector has undergone significant transformation in recent decades, evolving from a predominantly state-controlled domain to increasingly embracing private sector participation. Fighter jet production, a critical component of national defence, has traditionally been the preserve of public sector undertakings (PSUs) like Hindustan Aeronautics Limited (HAL). However, with the government’s push for indigenisation, self-reliance, and modernisation under initiatives like “Make in India,” the private sector is emerging as a vital player in this high-stakes industry. This article examines the intricacies of how private companies contribute to India’s defence capabilities and what lies ahead for this evolving partnership.

Historical Context

India’s journey into fighter jet production began in the mid-20th century, heavily reliant on foreign technology and licensing agreements. The 1960s saw HAL commence production of the Soviet-designed MiG-21 under license, marking the start of India’s aircraft manufacturing journey. Over the years, HAL expanded its portfolio, producing aircraft like the Jaguar, Mirage 2000, and Su-30 MKI, all under similar arrangements with foreign OEMs. These efforts established HAL as the cornerstone of India’s defence aviation industry, supported by other PSUs and the Defence Research and Development Organisation (DRDO).

The push for Indigenous fighter jet development gained momentum with the HF-24 Marut, designed by German engineer Kurt Tank in the 1960s. However, the Light Combat Aircraft (LCA) Tejas program, initiated in the 1980s by the Aeronautical Development Agency (ADA) with HAL as the production partner, represented a significant leap towards self-reliance. The Tejas, inducted into the Indian Air Force (IAF) in 2016, showcased India’s ability to design and build a modern fighter jet, albeit with substantial reliance on imported components.

Historically, private sector involvement in fighter jet production was minimal. The defence sector’s strategic importance, high capital requirements and restricted access to advanced technology confined manufacturing to PSUs. While effective in establishing a foundational aerospace industry, this PSU-centric model faced limitations in scalability, innovation, and meeting the IAF’s growing demands, setting the stage for private sector inclusion.

Policy Changes Enabling Private Sector Participation

A series of progressive policy reforms have driven the shift towards private sector involvement in defence manufacturing, including fighter jets. Launched in 2014, the “Make in India” initiative sought to bolster domestic manufacturing and reduce import dependency, with defence identified as a priority sector. This program encouraged private companies to participate in defence production by fostering a conducive business environment and promoting collaborations with global players.

A pivotal policy change was the liberalisation of Foreign Direct Investment (FDI) in defence. Previously capped at 26%, the FDI limit was raised to 74% under the automatic route in 2020, with provisions for up to 100% on a case-by-case basis for critical technologies. This opened doors for foreign OEMs to invest in India, often in partnership with private Indian firms, facilitating technology transfer and capacity building.

The Strategic Partnership (SP) Model, introduced in the 2017 Defence Procurement Procedure (DPP), marked another milestone. Designed to foster long-term collaborations between private Indian companies and foreign OEMs, the SP Model identifies private firms as Strategic Partners in manufacturing major defence platforms, including fighter aircraft. The selection process emphasises financial stability, technical expertise, and manufacturing capabilities to create a robust domestic defence industrial base.

Revisions to the DPP further supported this shift. The DPP 2016 introduced the “Buy (Indian-IDDM)” category—Indigenously Designed, Developed, and Manufactured—prioritising equipment with at least 40% Indigenous content. Offset clauses in defence contracts, mandating foreign vendors to invest a percentage of the contract value in India, have also incentivised partnerships with private companies. These policies collectively signal a departure from the PSU monopoly, inviting private sector innovation and investment.

Current Involvement of the Private Sector

The private sector’s role in Indian fighter jet production is multifaceted, spanning manufacturing, supply chain contributions, and support services. While HAL remains the primary assembler of fighter jets like the Tejas, private companies are increasingly integrated into the production ecosystem.

Supply Chain Contributions. In the Tejas program, private firms supply critical components and sub-systems. Dynamatic Technologies, for instance, manufactures the front fuselage of the Tejas, demonstrating the precision and reliability private players can offer. Larsen & Toubro (L&T) contributes to various aerospace projects, leveraging its engineering expertise, while Tata Advanced Systems Limited (TASL) participates in component manufacturing and assembly processes. These collaborations reduce HAL’s burden and enhance production efficiency, paving the way for a more robust and agile production ecosystem.

Offset Obligations. Major defence deals have catalysed private sector involvement. The 2016 Rafale deal with France’s Dassault Aviation, involving 36 fighter jets, included offsets worth billions. Reliance Defence and Engineering partnered with Dassault to fulfil these obligations, producing components and establishing a manufacturing facility in Nagpur. Such partnerships generate business for private firms, facilitating skill development and technology absorption.

Maintenance, Repair, and Overhaul (MRO). Beyond production, private companies are making inroads into MRO services, which are essential for maintaining fighter jet fleets. TASL has established advanced MRO facilities that service military and civilian aircraft, while Mahindra Defence Systems supports aerospace equipment. These services ensure operational readiness, a critical factor given the IAF’s ageing fleet.

Emerging Technologies. Some private firms are exploring adjacent fields like Unmanned Aerial Vehicles (UAVs). Companies like TASL and Adani Defence & Aerospace are developing drones and building aerospace expertise that could eventually support fighter jet programs. While UAVs differ from manned fighters, the technological overlap strengthens the private sector’s aerospace capabilities.

Technology Transfer and Innovation. Technology transfer remains a cornerstone of private sector growth. Collaborations with foreign OEMs provide access to advanced systems, such as radar and propulsion technologies, while joint ventures encourage co-development. Private firms also invest in innovation, exploring additive manufacturing (3D printing) and artificial intelligence to streamline production and reduce costs. Over time, these efforts could lead to fully indigenous fighter jet designs.

Role of MSMEs. Micro, Small, and Medium Enterprises (MSMEs) are the backbone of the aerospace supply chain. These firms produce smaller components—fasteners, wiring harnesses, and sub-assemblies—supporting larger private companies and PSUs. By integrating MSMEs, the industry can enhance efficiency and scalability, fostering a broader industrial ecosystem and providing opportunities for growth and innovation.

Key Defence Production Private Companies. Several private companies have shown interest in participating in fighter jet manufacturing, either independently or in collaboration with HAL and foreign OEMs.

- Tata Advanced Systems Limited (TASL) has emerged as a leader in India’s private aerospace sector. Its joint venture with Lockheed Martin to produce aero structures, including wings for the C-130J Super Hercules, showcases its manufacturing prowess. Although the F-16 production proposal did not materialise, TASL’s capabilities position it for future fighter jet projects.

- Mahindra Defence Systems. Mahindra has leveraged its automotive expertise to enter defence manufacturing, supplying aircraft components and expressing interest in the SP Model. Its partnership with Airbus for helicopter components reflects its ambition to expand into fighter jet production.

- Larsen & Toubro (L&T). L&T’s decades-long experience in defence engineering includes contributions to the Tejas and other platforms. Its advanced manufacturing facilities and focus on precision engineering make it a strong contender in aerospace production.

- Adani Defence & Aerospace. It aims to enhance India’s self-reliance in defence manufacturing. While active in UAVs, avionics, and MRO, it seeks partnerships for fighter jet production but lacks an indigenous fighter aircraft program.

Challenges Faced by Private Companies

Private companies face significant hurdles in entering fighter jet production despite growing involvement.

- High Capital Investment. Aerospace manufacturing demands substantial upfront investment in infrastructure, technology, and skilled manpower. The long gestation periods before returns materialise deter many firms, particularly more minor players.

- Technological Barriers. Fighter jet production requires mastery of complex technologies—avionics, propulsion, and materials science—that PSUs like HAL have developed over decades. Private companies often lack this expertise, relying on foreign partnerships that may limit technology transfer.

- Bureaucratic Procurement Processes. The defence procurement system is notoriously complex, with lengthy tendering, evaluation, and approval stages. This can discourage private firms accustomed to faster commercial cycles.

- Competition with PSUs. HAL’s entrenched position and government backing create an uneven playing field. Private companies must compete with HAL’s economies of scale and establish relationships with the IAF.

- Quality and Certification. Fighter jets demand uncompromising quality and safety standards. Private firms must navigate rigorous certification processes, such as those mandated by the Centre for Military Airworthiness and Certification (CEMILAC), adding time and cost.

Future Prospects

The private sector’s role in Indian fighter jet production is set for significant expansion, driven by policy continuity, market demand, and technological advancements. Government initiatives such as Atmanirbhar Bharat and the Defence Acquisition Procedure (DAP) foster a stable investment climate, encouraging private firms to engage in aerospace manufacturing. Policy measures like strategic partnerships and increased foreign direct investment (FDI) limits further enhance private sector participation.

Market demand is another key driver. The Indian Air Force (IAF) is undergoing rapid modernisation, with plans to replace ageing aircraft and induct advanced fighters. Additionally, India’s ambition to become a defence exporter presents lucrative opportunities for private companies. Countries in Southeast Asia, the Middle East, and Africa could become potential buyers, bolstering the case for increased private production.

Technological advancements are also reshaping the industry. Additive manufacturing, artificial intelligence, and advanced materials reduce entry barriers and enable new players to contribute. Collaborations with global aerospace firms can further accelerate technology absorption.

However, for private firms to succeed, key enablers must be addressed. Streamlining procurement processes, enhancing R&D funding, and developing a skilled workforce are critical. Bureaucratic hurdles and financial constraints have historically hindered private participation, but targeted reforms could unlock their full potential. If these challenges are managed effectively, private companies could be pivotal in next-generation fighter projects like the Advanced Medium Combat Aircraft (AMCA). This would strengthen India’s defence manufacturing ecosystem and enhance its strategic autonomy in aerospace technology.

Conclusion

The involvement of the private sector in Indian fighter jet production marks a paradigm shift from a PSU-dominated landscape to a collaborative ecosystem. While challenges like capital intensity and technological gaps persist, the opportunities—driven by policy reforms, IAF requirements, and global partnerships—are immense. Companies like TASL, Mahindra, and L&T exemplify the potential of private enterprises to enhance India’s defence capabilities. As the nation strives for self-reliance, the private sector’s role will be pivotal in shaping a robust, innovative, and competitive aerospace industry, ensuring that India’s fighter jets soar not just in the skies but also as symbols of industrial prowess and strategic autonomy.
