Pune-headquartered defence technology company Nibe Limited has reported a significant advancement in its unmanned systems programme, announcing the successful completion of initial technical trials of its loitering munition platform, the Vayu Astra-1. The development comes shortly after the firm’s demonstration of its long-range Suryastra rocket launcher system and represents another step in India’s ongoing effort to expand indigenous precision-strike capabilities.

The announcement, made on Thursday through a regulatory filing to stock exchanges, triggered a sharp market response, with Nibe Limited’s shares hitting a 20 percent upper circuit following the disclosure of successful trial results.

According to the company, the Vayu Astra-1 system was evaluated in response to a Request for Proposal (RFP) issued by the Indian Army, which is seeking a loitering munition capable of engaging targets at ranges of up to 100 kilometres while maintaining high accuracy, autonomous functionality, and operational flexibility in diverse terrain conditions.

To validate the system’s performance under realistic operational conditions, Nibe Limited conducted a series of structured trials across multiple locations, including the Pokhran Field Firing Range and high-altitude operational terrain near Joshimath (Malari).

The dual-location testing strategy was designed to assess both desert and mountainous combat environments, reflecting the varied geographic challenges faced by India’s armed forces along its western and northern borders.

In the Pokhran phase of testing, the Vayu Astra-1 demonstrated its primary strike capability. Equipped with a 10-kilogram high-explosive anti-personnel warhead, the system successfully engaged a target located 100 kilometres away on its first attempt. The company reported a Circular Error Probable (CEP) of under one metre, indicating a high degree of precision for a system in this category.

Such accuracy levels place the system within the higher tier of modern loitering munitions, which are increasingly designed to minimize collateral damage while maximizing target effectiveness.

Beyond strike accuracy, Nibe Limited highlighted a series of successful functional validations during the trials, focusing on the system’s autonomous decision-making and mission adaptability.

Controlled mission abortion

Real-time attack initiation

Re-attack sequencing in dynamic conditions

These features are considered critical for modern loitering munitions, which must operate in contested environments where targets may move, disappear, or require reassessment during engagement windows.

Company statements also emphasized successful testing of operator control flexibility. During the trials, command of the platform was transferred from a Ground Control Station to a Forward Control Station located approximately 70 kilometres away. This capability is designed to enhance battlefield survivability by allowing operators to maintain control from safer, more dispersed positions.

One of the most significant segments of the trial involved a night-time anti-armour mission designed to test the system’s infrared (IR)-guided targeting suite. In this scenario, the Vayu Astra-1 successfully engaged a designated armoured target using its onboard IR camera system, achieving a reported accuracy margin of approximately two metres.

Night-time precision engagement is a critical requirement for modern unmanned combat systems, particularly in high-threat environments where visibility is limited and adversaries operate under concealment. The successful execution of this test underscores the system’s potential utility in both surveillance-strike and deep interdiction roles.

A separate phase of evaluation was conducted in Uttarakhand’s mountainous terrain near Joshimath (Malari), where the system was tested at elevations exceeding 14,000 feet.

At such altitudes, thin air, reduced lift efficiency, and extreme temperature variations pose significant challenges to aerial platforms, particularly those carrying payloads such as warheads and sensor suites.

Despite these constraints, the Vayu Astra-1 reportedly achieved sustained flight endurance of more than 90 minutes, demonstrating stable performance and control reliability in high-altitude conditions. This capability is especially relevant for deployment scenarios along India’s northern borders, where terrain-induced operational limitations have historically complicated aerial missions.

In a notable deviation from conventional loitering munition design philosophy, Nibe Limited confirmed that the Vayu Astra-1 platform was recovered intact after testing rather than being expended upon target impact.

This recoverable architecture introduces potential cost efficiencies, particularly for training cycles, iterative testing, and mission rehearsal scenarios. Reusability is also seen as advantageous in development programmes, allowing multiple test iterations without requiring full system replacement after each engagement.

Industry analysts note that while most loitering munitions are designed as expendable “one-way” systems, hybrid recoverable models may become increasingly relevant in early-stage deployment or dual-use reconnaissance-strike platforms.

Loitering munitions—often referred to in military terminology as “kamikaze drones”—have become a defining feature of contemporary battlefield systems. These platforms combine the endurance of unmanned aerial vehicles with precision strike capability, allowing them to patrol designated zones before autonomously or semi-autonomously engaging high-value targets.

The Vayu Astra-1 fits into this emerging class of intelligent strike systems, which are being rapidly adopted across global militaries due to their flexibility, cost-effectiveness compared to traditional missile systems, and reduced dependency on manned aircraft.

Military observers note that such systems are particularly effective in asymmetric warfare environments, where rapid target identification and precision engagement are essential.

The successful demonstration of the Vayu Astra-1 is being viewed within broader discussions around India’s push for defence indigenisation and technological self-reliance under national industrial policy frameworks.

By developing long-range, precision-guided unmanned strike systems domestically, firms like Nibe Limited are contributing to reduced import dependency and expanded domestic defence manufacturing capacity.

The development also aligns with increasing procurement preferences for locally produced systems, particularly those that integrate artificial intelligence, autonomous navigation, and advanced sensor fusion technologies.

Defence analysts suggest that the emergence of private-sector players capable of delivering complex systems such as loitering munitions marks a structural shift in India’s defence industrial base, which has historically been dominated by public-sector undertakings.

The Vayu Astra-1 announcement follows closely on the heels of Nibe Limited’s earlier trials of its Suryastra rocket launcher system, which demonstrated extended-range precision strike capability.

Between May 18 and 19, the company conducted test firings of 150-kilometre and 300-kilometre rocket variants at the Integrated Test Range, Chandipur, marking another milestone in its expanding portfolio of indigenous strike platforms.

The Suryastra system is supported by a ₹293 crore emergency procurement contract awarded by the Indian Army earlier this year, underscoring growing institutional support for domestic alternatives in long-range artillery and rocket systems.

Together, the Suryastra and Vayu Astra programmes illustrate a broader convergence of rocket artillery and autonomous aerial strike technologies within India’s defence ecosystem.

The rapid progression of Nibe Limited’s defence portfolio reflects a wider trend in which private-sector firms are increasingly participating in high-end military technology development. This shift has been facilitated by policy reforms encouraging private investment in defence manufacturing and accelerated procurement pathways for indigenous systems.

As global conflicts continue to demonstrate the strategic importance of unmanned systems, India’s ability to produce its own loitering munitions, precision rocket systems, and autonomous strike platforms is likely to play a critical role in shaping future defence readiness.

The successful trials of the Vayu Astra-1 loitering munition represent a notable milestone for Nibe Limited and a broader indicator of India’s advancing capabilities in autonomous weapon systems. With demonstrated long-range precision, autonomous mission flexibility, night-strike capability, and high-altitude endurance, the system reflects the growing sophistication of domestically developed defence technologies.

 Russia has unveiled its Lancet-E loitering munition system for the first time at the Aero India 2025 international aerospace exhibition, marking a significant moment in Moscow’s ongoing push to expand its global defense exports. The Lancet-E, an export variant of the Lancet series used extensively by Russian forces in Ukraine, was presented by Rosoboronexport, Russia’s state arms exporter.

The unveiling comes as part of Russia’s broader participation at the defense expo, where over ten major Russian defense firms are showcasing more than 500 military products, signaling continued collaboration with India in the defense sector.

Lancet-E System: A Battlefield-Proven Precision Strike Weapon

The Lancet-E system consists of several components, including:

• The Product 52-E guided munition carrier
• The Product 51-E loitering munition
• The Z-16-E reconnaissance drone, which provides target acquisition and battle damage assessment

This system was previously showcased domestically at the Army 2024 International Military-Technical Forum and made its international debut at ADEX 2024 in Baku before being introduced to a wider audience in India.

Rosoboronexport emphasized that the Lancet loitering munition has proven its effectiveness in combat, particularly in counter-battery warfare, where it has been used to destroy NATO-supplied artillery systems in Ukraine.

According to Russian military reports, the Lancet-3 variant alone has been responsible for eliminating nearly 45 percent of NATO artillery systems deployed in the ongoing conflict since February 2022.

This includes the destruction of:

• M777 lightweight howitzers
• Polish KRAB Self-Propelled Guns (SPGs)
• Leopard Main Battle Tanks (MBTs)
• Radar installations and surface-to-air missile (SAM) batteries
• Small naval boats operated by Ukraine

The system’s performance in Ukraine has positioned it as one of the most widely used loitering munitions in modern warfare, a fact that Moscow is leveraging to promote it in international markets.

Russia Eyes Global Market for the Lancet-E

Rosoboronexport has high expectations for the Lancet-E, estimating its export potential to exceed 1,000 units, placing it among the leading loitering munitions available worldwide.

Speaking at a previous defense forum, Alexander Mikheev, Director General of Rosoboronexport, revealed that Russia is open to license production agreements and technology partnerships with foreign buyers.

“Once the needs of the Russian Armed Forces are met, we have the production capacity to supply the system internationally,” Mikheev stated.

While there has been no official confirmation that Russia has offered the Lancet-E to India, its display at Aero India 2025 indicates Moscow’s keen interest in expanding its footprint in the Indian defense market. India has been actively enhancing its drone capabilities, including acquiring loitering munitions for precision strikes.

Russia has traditionally been one of India’s largest defense suppliers, and the Lancet-E could emerge as a viable option for India’s armed forces, particularly given its growing focus on unmanned aerial combat systems.

Lancet’s Combat Capabilities

The Lancet series has established itself as a highly lethal loitering munition, capable of striking high-value targets deep behind enemy lines.

Equipped with a shaped-charge warhead, it is designed to penetrate heavily armored targets, including main battle tanks and fortified structures. However, its most significant battlefield contribution has been in counter-battery warfare, where it has neutralized dozens of NATO-supplied artillery systems.

The Lancet operates in a hunter-killer configuration, working alongside ZALA reconnaissance drones. These UAVs:

• Scan the battlefield for potential targets
• Pinpoint precise enemy positions
• Relay targeting data to the Lancet for precision strikes

In electronic warfare (EW) environments, where GPS jamming and radio interference are common, the ZALA drone acts as a communications relay, ensuring that the Lancet maintains control and guidance to its designated target.

Once launched, the Lancet accelerates in its final dive, striking with high precision. Each attack is recorded through aerial reconnaissance, with footage often shared by Russian military-affiliated sources, demonstrating multiple successive strikes on a single target until it is completely destroyed.

Lancet’s Technical Specifications

• Warhead Payload: 3-5 kg of high-explosive material
• Cruising Speed: 100 km/h (62 mph), accelerating 1.5 times faster in the final attack phase
• Armor Penetration: Up to 30 cm (11.8 inches) of reinforced armor
• Strike Radius: 30-80 km, allowing for deep-strike capability
• Telemetry System: Real-time target imagery transmission for strike confirmation
• Low Radar Signature: Flying at low altitudes to evade detection

Despite occasional reports of Lancet drones being shot down, they remain highly effective due to their stealth profile, low radar signature, and short flight duration, which leaves adversaries with minimal reaction time.

India’s Growing Interest in Loitering Munitions

India has been actively expanding its drone warfare capabilities, with increasing investments in unmanned aerial vehicles (UAVs) and loitering munitions. The Indian Army and Air Force have already procured several UAV platforms, including:

• Israeli Harop loitering munitions
• Indian-made Swarm Drone systems
• American MQ-9 Reaper drones (leased for reconnaissance missions)

Given this trend, the Lancet-E could emerge as a viable contender if India chooses to explore Russian loitering munition systems for its arsenal.

Additionally, the India-Russia defense partnership has been strong for decades, with joint projects like the BrahMos supersonic cruise missile setting a precedent for technology transfers and localized production.

Russia’s openness to license production deals could further enhance its chances of securing orders from India, especially if New Delhi is interested in manufacturing loitering munitions domestically as part of its “Make in India” initiative.

Russia’s Defense Presence at Aero India 2025

Russia’s participation in Aero India 2025 is one of the largest among foreign exhibitors, with more than ten Russian defense firms presenting over 500 military products.

In addition to the Lancet-E, Russia is also showcasing:

• Su-57 and Su-75 Checkmate fighter jets
• S-400 and Pantsir-S1 air defense systems
