Noida-based aerospace startup EndureAir Systems has been awarded financial backing from the Indian government's Research, Development, and Innovation (RDI) programme.
This funding will drive the creation of the SABAL-200, an advanced, heavy-lift unmanned aerial vehicle (UAV) tailored for logistics in both the defence sector and crucial infrastructure projects.
This investment is part of the broader ₹1 lakh crore RDI Scheme, launched in November 2025 under the Anusandhan National Research Foundation.
Managed by the Technology Development Board (TDB), the initiative commenced its initial fund disbursements in May 2026 to foster homegrown deep-tech advancements in aerospace, space, and autonomous systems.
Experts in the field consider the support for the SABAL-200 a significant leap forward for India's unmanned logistics network.
It marks a decisive shift towards adopting high-capacity drones that can stand in for crewed helicopters during perilous missions.
Founded in 2018 by IIT-Kanpur alumni, EndureAir is significantly scaling up its technology with this new project.
The SABAL-200 is a massive upgrade from the company's previous SABAL-20 model, a drone that has reportedly seen active service with the Indian Army for supply drops in elevated terrains like Ladakh.
Whereas the older SABAL-20 could lift 20 kilograms of cargo, the SABAL-200 is engineered to hoist an impressive 200 kilograms.
This tenfold increase catapults India's domestic capabilities into a much higher tier of automated aerial transport.
Such a substantial payload boost completely transforms how these unmanned platforms can be utilised.
It allows for the airborne delivery of hefty ammunition crates, fuel reserves, construction gear, and large quantities of medical aid—tasks historically reserved for piloted aircraft.
Deviating from the standard multi-rotor drone design, the SABAL family utilises a variable-pitch, electric tandem-rotor layout.
This heavy-lift structure closely mirrors the proven twin-rotor blueprint of the famous Boeing CH-47 Chinook helicopter.
This specific aerodynamic approach is highly advantageous for carrying substantial weight in areas with thin atmosphere, like the Himalayas, where traditional aircraft struggle to maintain adequate lift.
The twin-rotor setup ensures exceptional stability for the cargo, maximises lifting power, and guarantees dependable performance even when navigating treacherous mountain ranges or facing harsh weather.
Transforming Military Operations
For India's armed forces, these UAVs will be a vital asset for frontline supply chains in high-altitude border regions.In these sectors, unpredictable weather, rugged landscapes, and a lack of landing infrastructure frequently hinder standard helicopter flights.
The introduction of a self-flying, 200-kilogram capacity drone carries massive implications across both military and civilian domains.
Within the defence framework, the SABAL-200 could significantly lessen the military's reliance on crewed light helicopters, like the ageing Cheetah and the HAL Dhruv, for everyday supply runs in challenging territories.
Automated drones can easily take over monotonous, high-risk "mule" duties—ferrying food, fuel, and weapons.
This frees up valuable piloted aircraft and their crews to concentrate on critical tasks such as combat assistance, medical evacuations, troop deployments, and rescue operations.
To ensure safety and reliability during these complex missions, the SABAL systems are equipped with dual GPS backups, automatic return-to-home (RTH) protocols, and emergency parachutes for secure Beyond Visual Line of Sight (BVLOS) operations.
Transitioning to uncrewed logistics also drastically reduces the physical danger to pilots who otherwise have to navigate blinding snowstorms, tight mountain gorges, and sudden weather shifts in the Himalayas.
Bolstering Civilian Infrastructure
Outside the realm of national security, EndureAir has highlighted the SABAL-200's potential to bolster essential civilian infrastructure, particularly in the energy sector.The heavy-lift drone is ideally suited for hauling machinery to isolated solar and hydroelectric plants.
It can also perform maintenance duties in hard-to-reach locations and aid in the complex process of stringing power lines for high-voltage grids across mountainous terrains.
As India continues to rapidly expand its border roads and renewable energy networks, the need for automated, heavy-duty cargo drones is projected to surge, especially in remote regions entirely cut off from conventional road networks.
