India’s Drone Revolution: From TAPAS Trials to Export Ambitions
In a landmark shift for Indian defence aviation, the Defence Research and Development Organisation (DRDO) has accelerated trials of the TAPAS BH-201 Medium Altitude Long Endurance (MALE) drone, marking a pivotal step in India’s quest for self-reliant unmanned aerial systems (UAS). As of mid-October 2025, recent flight tests at Chitradurga’s Aeronautical Test Range have demonstrated enhanced endurance and payload capabilities, positioning TAPAS as a game-changer for the Indian Armed Forces. This comes amid a global drone boom, where India’s market is projected to hit $3 billion by 2029, driven by border surveillance needs and export deals. But how far has India come in this revolution, and what challenges lie ahead? Let’s dive into the tech, integrations, and strategic implications.
The Rise of TAPAS BH-201: Specs and Recent Milestones
The TAPAS (Tactical Airborne Platform for Aerial Surveillance-Beyond Horizon 201) is DRDO’s indigenous response to global MALE drones like the MQ-9 Reaper or Heron TP. Developed by the Aeronautical Development Establishment (ADE) in Bengaluru, it first flew in 2016 but faced delays due to engine and integration issues. Fast-forward to 2025: Recent trials in September-October have clocked over 20 hours of flight time, with altitudes reaching 28,000 feet and speeds up to 200 km/h.
Key technical highlights:
- Endurance and Range: 24+ hours of loiter time, with a 1,000 km operational radius—ideal for ISR (Intelligence, Surveillance, Reconnaissance) over Ladakh or the Indian Ocean Region.
- Payload Capacity: Up to 350 kg, supporting electro-optical/infrared (EO/IR) sensors, synthetic aperture radar (SAR), and electronic intelligence (ELINT) modules. Future variants could arm it with precision-guided munitions like the Helina missile.
- Powerplant: Powered by two indigenous PTCAE-7 turbocharged engines (or imported alternatives like Austro AE300 for reliability), achieving a service ceiling of 30,000 feet.
- Avionics Edge: SATCOM for beyond-line-of-sight control, AI-driven autonomy for swarm operations, and anti-jamming features tested against simulated threats.
These advancements stem from post-2023 user trials feedback from the Indian Air Force (IAF) and Navy, where TAPAS demonstrated real-time data relay during the Swami Vivekananda exercise in Rajasthan (August 2025). In that drill, it integrated seamlessly with ground stations, providing live feeds that enhanced artillery targeting by 15-20% in simulated scenarios, per DRDO reports.
Integration with Armed Forces: Post-Swami Vivekananda Insights
The IAF’s acquisition roadmap includes inducting 10 TAPAS units by 2026, with the Navy eyeing maritime variants for anti-submarine warfare. Post the Swami Vivekananda joint exercise (involving IAF’s Garuda and Army’s Sudarshan Chakra elements), TAPAS proved its mettle in multi-domain ops:
- IAF Role: Replacing imported Searcher/Heron drones for border patrols along the LAC (Line of Actual Control). Integration with the Integrated Air Command and Control System (IACCS) allows real-time sharing with Su-30MKI fighters.
- Army Synergies: Paired with counter-drone systems like the Bharatiya Counter Drone System (BCDS), tested against Pakistani Shaheen drones in Op Sindoor validations.
- Navy Ambitions: Deck-based trials on INS Vikrant for carrier ops, focusing on anti-piracy in the Arabian Sea.
Private sector involvement is key here—companies like ideaForge and NewSpace Research are supplying sub-systems, boosting indigenization to 70%. This aligns with the Defence Acquisition Procedure (DAP) 2020 reforms, where private firms like Tata Advanced Systems are co-developing variants.
Private Players and Market Dynamics: Adani’s Drishti-10 Leads the Charge
While DRDO leads strategic drones, the private ecosystem is exploding. Adani Defence’s Drishti-10 Starliner (Hermes 900 equivalent) was inducted into the Navy in January 2025, with 60 units ordered. Its highlights:
- Maritime surveillance focus: 36-hour endurance, armed with anti-ship missiles.
- Export-Ready: Certified under MTCR (Missile Technology Control Regime) guidelines.
Other players:
- Garuda Aerospace: Agri-drone tech pivoting to defence with swarm capabilities.
- Zen Technologies: Simulators for drone pilots, used in IAF training.
The $3B market projection (per NITI Aayog) includes $1.5B in exports by 2029. Challenges? Import dependency on components (e.g., Israeli sensors) and regulatory hurdles under DGCA’s drone rules 2021.
| Drone Model | Endurance (hrs) | Altitude (k ft) | Payload (kg) |

| Drishti-10 (India) | 36 | 30 | 450 |
| MQ-9B Reaper (US) | 27 | 50 | 1700 |
| Heron TP (Israel) | 36 | 45 | 1000 |

Counter-Drone Tech and Border Threats: A Strategic Imperative
Amid rising drone incursions (e.g., 150+ from Pakistan in 2024 per MoD), India’s counter-UAS focus is critical. Systems like the Indrajal (Gripenomics) use AI to detect and neutralize swarms via lasers/jammers. Recent deals: Armenia procured Indian Akash-NG integrated drones post-2024 Nagorno-Karabakh lessons, signaling export wins. Deals worth $500M are in pipeline with Vietnam and Philippines for surveillance drones.
Geopolitically, this counters China’s Wing Loong series along the LAC. X threads from @DefenceDecode emphasize how drone swarms could redefine warfare, with India investing ₹5,000 Cr in R&D via iDEX (Innovations for Defence Excellence).
Challenges and the Road Ahead: Atmanirbhar in Swarm Ops
Hurdles remain: Engine tech lags (relying on US GE or Ukrainian imports), cyber vulnerabilities, and talent shortages. Yet, initiatives like the Drone Shakti scheme aim to produce 1 lakh pilots by 2030.
In conclusion, from TAPAS trials to export ambitions, India’s drone revolution embodies Atmanirbhar Bharat’s core—reducing imports from 60% to 30% in UAS by 2027. As PM Modi stated at DefExpo 2024, “Drones are the eyes of modern warfare.” With swarm tech on the horizon (DRDO’s 2026 demo), India is not just catching up but poised to lead in affordable, lethal UAS. Watch for TAPAS induction updates; this could reshape regional deterrence.
