Sheshnaag-150 signals a strategic shift with the arrival of relatively low-cost deep strike and saturation options for Armed Forces that need not stockpile large numbers of cruise missiles

On February 11, 2026, Indian firm NewSpace Research & Technologies showcased the Sheshnaag-20 canister-launched loitering munition at the World Defence Show (WDS) 2026 in Riyadh, Saudi Arabia, presenting a compact electric drone designed for ground and vehicle launch. Sheshnaag-20, a new canister-launched loitering munition developed for deployment from ground positions or from vehicles. The presentation highlighted a compact, electrically powered system intended to combine surveillance and strike functions within a single platform.
The Sheshnaag-20 platform is an electric fixed-wing design powered by batteries and propelled by a brushless DC motor. According to the technical data released during the exhibition, the munition features a wingspan of two meters and a maximum take-off weight of 20 kgs. It can accommodate a payload of up to five kgs. The canisterised configuration is intended to simplify handling, storage and launch procedures while supporting transport on a variety of military vehicles.
Performance figures provided by the manufacturer indicate an endurance of approximately one hour and an operational range of 30 km
Performance figures provided by the manufacturer indicate an endurance of approximately one hour and an operational range of 30 km. The Sheshnaag-20 can reach a maximum operating altitude of 6,000 meters above mean sea level and fly at speeds of up to 150 km/h. These characteristics are designed to allow the system to transit quickly toward an objective area and then remain available for search and identification tasks before a strike decision is made.
NewSpace Research & Technologies is active in the development of unmanned and autonomous systems for defence applications. In recent years it has positioned itself in segments ranging from intelligence, surveillance and reconnaissance (ISR) to precision engagement, with an emphasis on modular designs and scalable architectures. The Sheshnaag-20 forms part of this portfolio and illustrates the firm's effort to address requirements expressed by Armed Forces seeking indigenous capabilities that can be rapidly fielded and integrated with existing formations.
For mission execution, the platform integrates a high-performance electro-optical and infrared (IR) camera intended to support target acquisition under different environmental conditions. In its strike role, it can be equipped with a high-explosive or anti-tank warhead, including a five-kilogram HEAT configuration. The company states that the munition has been conceived with a significant level of autonomy and can be employed in coordinated groups, enabling what is often described as a concentration of effects while keeping operator workload limited. The system's arrival on the international stage underscores the speed at which loitering munitions continue to evolve, driven by demands for responsiveness, precision and adaptability across a wide spectrum of operational environments.
With the Sheshnaag-20, NewSpace Research & Technologies is proposing a solution that combines portability, integrated sensing and a selectable lethal payload within a relatively lightweight air vehicle. Its introduction at WDS 2026 offers potential users an opportunity to assess how such capabilities might fit into future force structures, where unmanned assets are expected to play an increasingly central role alongside conventional platforms.

The Sheshnaag loitering munition series, developed by NewSpace Research and Technologies, includes the Sheshnaag-150 variant which has a range exceeding 1,000 km, over five hours of endurance, and AI-powered swarm capabilities. It is designed for deep-strike missions, carries a 25-40 kg warhead, and can be rapidly deployed from a single truck. This AI-powered, long-range loitering munition is designed to execute coordinated and autonomous swarm strikes with extreme precision. Unlike traditional loitering munitions, which act individually, Sheshnaag 150 units communicate with each other to coordinate strikes on high-security targets. Deploying these drones is effortless; a single truck can carry 20+ units, ready for rapid deployment from remote locations.
The configuration shown at WDS 2026 is a compact, low-aspect delta wing with a central dorsal fin and a rear propulsion section, a layout optimised for simple manufacture, internal fuel volume, and stable long-range cruise. The endurance figures emerging from multiple reports suggest an efficient small engine architecture rather than a purely electric design. Sheshnaag-150 has been described as a 150 kg-class long-range precision strike UAV with an endurance of around five hours, while retaining the payload bracket seen in the Riyadh brochure.
NewSpace highlights work on intelligent cyber-physical uncrewed systems, including self-healing swarms, dynamic re-tasking, and advanced mesh networking, all of which align with a concept of launching multiple vehicles that cooperate rather than merely fly the same route. During early flight activity, the system reportedly demonstrated target engagement with an indicated CEP of five metres. Operationally, a 1,000+ km loitering munition with a 25-40 kg warhead class sits in the deep-strike gap between tactical backpack systems and expensive stand-off missiles.

In a conventional campaign, Sheshnaag-150 would be most valuable for pre-emptive and follow-on strikes against air defence (AD) nodes, command posts, fuel and ammunition points, airfield infrastructure, and fixed high-value assets where a single hit creates cascading disruption. The loitering attribute adds a tactical edge: launched on a permissive route, the munition can wait for time-sensitive cues, refine aimpoints through onboard sensors, and strike when the target pattern confirms, reducing wasted salvos compared with purely pre-planned one-way drones.
Employment of collaborative attacks would force defenders into an economic and tactical dilemma by presenting many simultaneous problems. A country could disperse launchers on trucks or trailer-based racks, fire mixed packages, and use networked coordination to split roles between decoys, ISR scouts, electronic support collectors, and lethal strikers. This allows a commander to shape an AD picture, provoke radar emissions, map engagement zones, and then drive a saturation wave through a seam. The same architecture also supports maritime coercion, with loitering munitions used to hold chokepoints and coastal approaches at risk, or to complicate naval air defences through multi-axis arrivals.
The concept of Sheshnaag-150 is akin to Israel's Harop loitering munitions. It is a theatre-level strike tool intended to reach deep targets from outside most counter-battery and short-range AD threats Sheshnaag-150 signals a strategic shift; arrival of relatively low-cost deep strike and saturation options for Armed Forces that need not stockpile large numbers of cruise missiles.
