India’s ambition to establish a formidable and self-reliant unmanned aerial vehicle (UAV) manufacturing ecosystem has taken a significant leap forward.
Dr. Samir V. Kamat, Chairman of the Defence Research and Development Organisation (DRDO), has confirmed that vital technologies created during the TAPAS Medium Altitude Long Endurance (MALE) UAV programme are now being shared with private companies.
This strategic transfer is designed to rapidly build domestic capabilities as numerous Indian enterprises prepare to participate in an upcoming tri-services tender for 87 MALE UAVs, a massive "Make in India" project estimated to be worth over ₹25,000 crore.
The highly anticipated procurement drive has generated tremendous interest across the defence industry, with nearly two dozen companies expected to submit bids.
The competition will feature a mix of purely domestic designs and joint ventures formed between Indian firms and foreign original equipment manufacturers (OEMs).
Recent reports indicate that leading Indian corporations are actively finalising strategic partnerships with global aerospace giants from Israel and the United States, underscoring the immense strategic and commercial value of India's unmanned systems market.
According to defence sources, private manufacturers specifically requested access to various essential subsystems and foundational technologies originally engineered for the TAPAS drone.
These specific components are fundamental for private players to quickly achieve operational reliability and maturity in producing heavy, MALE-class aviation platforms.
One of the most critical technologies handed over is the robust tricycle landing gear framework. This system is specifically designed to handle the intense physical stress of Autonomous Take-Off and Landing (ATOL) procedures.
Paired with DRDO’s proprietary ATOL software, this capability is an absolute necessity for operating large drones from rugged, semi-prepared runways in remote regions.
Furthermore, DRDO has shared its advanced Flight Control System (FCS) architecture, which includes digital fly-by-wire technology, control laws, and the Flight Control Computer (FCC).
These intricate systems act as the brain of the aircraft, ensuring it remains stable in the air, adapts to changing mission parameters, and safely executes autonomous flight patterns during extended surveillance operations.
To guarantee precise targeting and routing, the drones are being integrated with India’s homegrown GAGAN (GPS Aided GEO Augmented Navigation) network.
By utilising this domestic system, the UAVs achieve high-accuracy positioning without remaining completely dependent on foreign-controlled satellite networks, a key step towards absolute strategic autonomy in military navigation.
High-altitude propulsion efficiency is another major focus. Private manufacturers now have access to sophisticated Engine Control Units (ECUs) developed by the agency.
These digital controllers dynamically regulate engine parameters in mid-flight to minimise fuel consumption and sustain peak performance across diverse altitudes and mission scenarios.
Because seamless communication is the backbone of any unmanned mission, DRDO’s advancements in data-link technology are particularly valuable.
Private partners are receiving C-band and Ku-band satellite communication (SATCOM) systems, alongside Line-of-Sight (LoS) hardware.
These advanced antenna frameworks guarantee constant data flow and control, offering a direct LoS range of 250 kilometres and virtually limitless reach when connected via satellite networks.
In addition to standard communication gear, the technology transfer includes specialised repeater payloads.
When equipped with these devices, the UAVs can serve as flying communication towers, bouncing signals over geographical obstacles to heavily assist ground troops deployed in deep valleys or signal-denied mountainous environments.
On the ground, operational standardisation is being achieved through the Universal Ground Control Station (UGCS).
This highly modular command centre is built with uniform software and hardware architectures, allowing military operators to pilot multiple different types of UAVs from a single interface. This greatly reduces operational complexity and training requirements for the armed forces.
Ultimately, this comprehensive sharing of intellectual property highlights a major transformation in DRDO’s operational philosophy.
Instead of solely focusing on building solitary platforms, the organisation is actively functioning as an ecosystem enabler, distributing foundational technologies to fuel private sector innovation.
As the Ministry of Defence reportedly plans to split the upcoming 87-drone order between two separate local manufacturers to secure dual supply lines, this technology transfer ensures India is well-positioned to replace imported drone fleets with a robust, scalable, and export-ready domestic defence aviation industry.
