The Defence Research and Development Organisation (DRDO) successfully flight-tested its indigenous High-Altitude Platform System (HAPS) on 6 October 2026. It climbed to 21 km above sea level, held about 20 km for over 30 minutes, then descended on command and was recovered safely.
Key facts
| Built by | ADRDE (Aerial Delivery Research and Development Establishment), Agra |
| Type | Lighter-than-air, long-endurance surveillance platform |
| Altitude | 21 km, in the stratosphere |
| Data | Live video and vehicle data sent to the Ground Control Station |
| Same week | Advanced High-Altitude Parachute (AHAP): first live jump from 16,000 ft at Nyoma, Ladakh |
Background
- Why HAPS? Like a pseudo-satellite, it can hover over one area for long periods for surveillance, reconnaissance and communications (ISR) and disaster monitoring; it is cheaper than a satellite and can be recovered and repaired.
- Layers of the atmosphere: troposphere (0-12 km, weather) → stratosphere (12-50 km, ozone layer) → mesosphere (50-80 km, meteors burn up) → thermosphere (ionosphere).
- Earlier trial: in May 2025 DRDO flew a stratospheric airship to about 17 km (56,000 ft) for 62 minutes at Sheopur, Madhya Pradesh.
- DRDO: set up in 1958; HQ New Delhi; about 50 labs under the Defence Ministry.
Tamil Nadu link: DRDO's CVRDE (Combat Vehicles R&D Establishment) at Avadi, Chennai, designed the Arjun tank. Tamil Nadu's Defence Industrial Corridor (Chennai, Hosur, Coimbatore, Salem, Tiruchirappalli) is growing aerospace and defence manufacturing.
