NextLeap Aeronautics Climbing India’s Defence-Tech Value Chain

Bengaluru. In the rapidly evolving landscape of global defence technology, a quiet but determined transformation is underway in India. At the centre of this shift is NextLeap Aeronautics, a Bengaluru-based deep-tech aerospace venture that is steadily moving up the value chain, from building subsystems to delivering integrated platforms, and ultimately, complete mission-ready solutions.

In an interaction with India Strategic, co-founder Alvin Anthony outlined a journey shaped as much by crisis as by conviction. This reflects broader changes in India’s defence ecosystem and the urgent global push toward technological self-reliance.

Crisis as Catalyst

For NextLeap, the turning point was not a breakthrough contract or a major funding round, but survival. The COVID-19 pandemic nearly brought the company to a halt. Aerospace, dependent on physical testing, infrastructure, and close collaboration, was among the hardest hit sectors. Operations stalled, revenues dried up, and uncertainty loomed large. “At one stage, we even advised team members to seek other opportunities, unsure whether the company could endure.”

Yet, as global systems reopened in 2021, a new opportunity emerged.

Private players in drones and unmanned systems began recognizing a rare capability within NextLeap: end-to-end expertise spanning design, testing, certification, and system integration, built through experience at global giants like Airbus and Rolls-Royce.

Projects followed. Initially small, they soon expanded in scale and complexity. The company pivoted, taking on external assignments, building systems for clients, and, in the process, sharpening its engineering edge.

Building Capability Through Execution

Between 2021 and 2023, NextLeap underwent an intense phase of technological consolidation.

One of its early breakthroughs was the prototype development of a single-seater electric vertical take-off and landing (eVTOL), designed for personal aerial mobility. Built across India and Europe, the system progressed to early-stage flight testing, marking a significant validation of the team’s design and integration capabilities.

At the same time, the company became deeply embedded in India’s emerging drone ecosystem. From agricultural UAVs to jet-powered systems, it worked across multiple programs, designing, iterating, and deploying under tight timelines.

A standout achievement during this period was a high-altitude propulsion system tested in Leh, an environment where thin air and extreme temperatures challenge conventional drone performance. The successful deployment addressed a critical operational gap and demonstrated the company’s ability to engineer for India’s unique conditions.

Equally significant was the development of a carbon-fibre subscale drone platform capable of carrying a 10 kg payload, scalable to 40 kg. These projects not only generated revenue but also validated the company’s transition from concept-driven work to real-world execution.

The Shift to Defence

By 2024, NextLeap had stabilized, with a 40-member engineering team, multiple certifications, and a growing portfolio of deployments. This stability enabled a return to its core ambition: building cutting-edge aerospace products.

But this time, the focus was clear, defence. The shift was driven by both opportunity and necessity. Modern warfare, increasingly defined by unmanned systems, electronic warfare, and rapid-response capabilities, has created demand for agile, indigenous solutions.

One of NextLeap’s first major defence innovations was a fibre-optic-based FPV drone developed for the Indian Army. Unlike conventional drones that rely on RF communication, highly vulnerable to jamming, this system uses fibre-optic links, making it immune to electronic interference.

The insight drew heavily from lessons observed in the Russia-Ukraine conflict, where electronic warfare has reshaped battlefield dynamics. Secure, jam-resistant communication has become not just an advantage, but a necessity. The result was a domestically developed drone capable of day and night operations, precision payload deployment, and reliable performance in contested environments.

Import Substitution as Strategy

A defining feature of NextLeap’s approach is its emphasis on indigenization. In high-security deployments, reliance on foreign platforms, particularly from China, poses both operational and strategic risks. Even advanced systems from countries like Israel come with cost and support challenges, often making them impractical for sustained deployment.

NextLeap’s solution has been to build domestically, collaborating with Indian partners to develop critical subsystems, from communication architecture to flight control systems.

While certain components, particularly semiconductors, are still sourced globally, from manufacturing hubs in Taiwan and the Philippines, the integration happens entirely in-house. This ensures control over system behavior, security, and performance.

Winning Trust

Technology alone does not win defence contracts, trust does. NextLeap’s systems have undergone multiple trials with Indian Army units across regions such as Jammu & Kashmir and Punjab. In these evaluations, the company’s drones consistently ranked among the top performers, often securing positions in the top three.

This consistency has translated into credibility. Rather than developing in isolation, the company works closely with end users, incorporating feedback directly into product design. This has enabled rapid iteration and alignment with real-world requirements.

One such evolution was the development of indigenous RF communication systems, enabling drones to operate reliably over distances of 5 to 10 kilometers, even in challenging conditions.

Moving Up the Value Chain

Perhaps the most significant shift, however, lies in how NextLeap is redefining its role. “We started with subsystems,” Anthony noted. “But the goal is to move toward integrated platforms and eventually, complete solutions.” This progression is evident across its product roadmap.

From multi-rotor drones, the company has moved into fixed-wing UAVs, designed for longer endurance missions. Its platform, Aistha, is a lightweight, backpackable UAV capable of two-hour flights, covering distances of up to 20 kilometers.

Designed for intelligence, surveillance, target acquisition, and reconnaissance (ISTAR), the system includes custom software for real-time artillery correction, being developed in collaboration with field users. This integration of hardware and software marks a key transition, from component-level engineering to system-level thinking.

High-Speed Strike Systems: The Next Frontier

Building on its experience, NextLeap is now exploring high-speed UAV platforms, addressing a critical gap in modern warfare. Traditional loitering munitions, while effective, operate at relatively low speeds, making them vulnerable to interception. Inspired by global developments, the company is designing a jet-powered UAV capable of operating at significantly higher speeds. The platform aims to combine speed, reach, and impact, offering a new category of strike capability.

Early validation has already begun, with a laboratory under Defence Research and Development Organisation placing initial orders for testing airframes.

Autonomous Surveillance and Smart Systems

Alongside offensive capabilities, NextLeap is also advancing autonomous surveillance technologies. Its “drone-in-a-box” system represents a shift toward persistent, automated monitoring. These docking stations house drones that can be deployed on demand, execute missions autonomously, and return for recharging, all with minimal human intervention. The system is designed for security applications ranging from military bases to critical infrastructure.

Future iterations aim to integrate AI-driven analytics and link with CCTV networks, creating a layered, autonomous security architecture capable of real-time response.

Building an Ecosystem

A key differentiator for NextLeap is its ecosystem-driven approach. Rather than building everything in-house, the company collaborates with a network of Indian partners, spanning manufacturing, electronics, propulsion, and software. This distributed model allows for scalability while maintaining control over system integration.

Significantly, it is also helping build a domestic supply chain. For instance, drone motors, once largely imported, are now being developed locally in collaboration with Indian partners, reducing dependency on foreign suppliers.

Lessons from Ongoing Conflicts

NextLeap’s evolution must be seen against a broader global backdrop. The ongoing conflicts, from Ukraine to the Middle East, have demonstrated the decisive role of drones, loitering munitions, and autonomous systems. Speed, adaptability, and electronic resilience are redefining battlefield requirements.

At the same time, supply chain vulnerabilities and geopolitical tensions are pushing countries toward self-reliance. India, long dependent on imports for defence equipment, is now actively encouraging domestic development. Policies promoting indigenization, combined with increasing openness to startups, are creating new opportunities.

For NextLeap, the journey is far from complete. The company’s roadmap is clear: move from subsystems to platforms, and from platforms to complete, mission-ready solutions. This includes expanding into long-endurance UAVs, advanced propulsion systems, and integrated defence networks. It also involves securing certifications, building credibility, and scaling production.

Equally important is maintaining agility. In a sector where timelines often stretch into years, NextLeap’s ability to develop and deploy systems within months has become a competitive advantage.

A Strategic Shift

What began as a survival story has evolved into a strategic narrative. From near shutdown during the pandemic, the company’s trajectory reflects both resilience and vision. More importantly, it signals a broader shift in India’s defence ecosystem, toward indigenous capability, systems integration, and technological sovereignty.

As Anthony put it, the goal is not just to build products, but to build an ecosystem where India can design, develop, and deploy its own defence technologies. In an era defined by uncertainty and rapid technological change, that ambition may well prove to be not just relevant, but essential.
