Made-in-India drones by Tata Advanced Systems Operation Sindoor, marking defence tech milestone
Tata Advanced Systems
(TAS) has announced that it has expanded its domestic capabilities in
unmanned aerial vehicles
(UAVs) and
remotely piloted aircraft
(RPA), covering the complete design, development, and production of core subsystems. These include airframes, autopilots, and ground control software. The systems are now equipped with payloads such as high-resolution cameras, LiDAR, and multispectral sensors, and are designed to be fully autonomous and portable for field use.
The company stated that its in-house autopilot and mission control software allow for custom integration of payloads and user interfaces for different types of missions.

ALS 50 Mk II
: An upgraded version that has undergone flight testing and is built on technologies already in use by
security
agencies.
IVTOL
: A surveillance UAV capable of operating in unprepared environments. It includes gimbaled day/night cameras and onboard image processing. It has been tested for surveillance and target tracking.
'These systems are built on proven platforms and incorporate cutting‑edge technology to ensure reliable performance in a variety of operational environments,' the company said in a statement.
Features and mission capabilities
The company said the Advanced Loitering System supports autonomous missions with limited operator involvement. Features include real-time electro-optical and infrared video feeds, in-flight fail-safes, abort and recovery functions, and adaptability for re-targeting. The systems are designed to function in a variety of weather and terrain conditions.
TAS also highlighted its
VTOL UAV
designed for difficult locations such as hilltops, jungle areas, and ship decks. The drone weighs around 18 kg, has an operational range of over 15 km (extendable to 25 km), a flight time of up to two hours, and can operate at altitudes of up to 3,000 metres. It transitions from vertical to fixed-wing flight automatically and supports mission-specific payloads.
Drones used during Operation Sindoor
Several drones were used by India during
Operation Sindoor
, a cross-border counter-terrorism operation carried out in May 2025. The drones supported reconnaissance and targeting, helping in the execution of precision strikes with limited collateral damage. The systems were operated in active combat conditions.
