DRDO High Altitude Platform completes maiden flight trial
Why in the news
The Defence Research and Development Organisation (DRDO) announced on 6 October 2026 the successful maiden flight trial of an indigenously built High Altitude Platform.
Key facts
- Altitude: peaked at roughly 21 km above mean sea level (AMSL).
- Endurance in trial: held a steady 20 km AMSL for more than 30 minutes, after which it was recovered.
- Developer: Aerial Delivery Research and Development Establishment (ADRDE), Agra.
- Type: a lighter-than-air system meant to lead to long-endurance stratospheric aerial surveillance.
- On board: inertial measurement unit, GPS receiver, cameras and an altitude control mechanism; live video and flight data reached the ground control station.
- Coordination: Indian Air Force, CEMILAC, DGCA, Airports Authority of India and civil authorities.
| Parameter | Value |

| Hover altitude | 20 km AMSL |
| Time at hover altitude | Over 30 minutes |
| Lab | ADRDE, Agra |
About the platform
High altitude platforms operate in the stratosphere, well above normal air traffic, and can offer persistent watch over large areas. Defence Minister Rajnath Singh and Defence Secretary Rajesh Kumar Singh congratulated the DRDO team.
Exam angle
- ADRDE is located in Agra.
- Key numbers: 21 km peak, 20 km for 30+ minutes.
- Linked to surveillance and self-reliance in defence technology.
