India has launched an ambitious ₹15,000 crore programme to develop indigenous stratospheric surveillance airships capable of conducting long-duration intelligence, surveillance, and reconnaissance (ISR) missions from altitudes exceeding 20 kilometres. The project, being executed under the Make-I defence procurement framework, aims to build Air Ship-based High Altitude Pseudo Satellites (AS-HAPS) that can remain airborne for months while carrying advanced surveillance payloads.
The initiative is being overseen by the Indian Air Force’s Directorate of Operations (Remote) and has already received approval from the Defence Acquisition Council (DAC). Under the Make-I framework, the government can fund up to 70% of research and development costs, encouraging private-sector participation in one of India’s most advanced indigenous aerospace programmes.
India Launches ₹15,000 Crore Airship Programme
The project aims to bridge the surveillance gap between drones and satellites.
| Project Overview | Details |
|---|---|
| Project cost | ₹15,000 crore |
| Platform | Air Ship-based High Altitude Pseudo Satellite (AS-HAPS) |
| Operating altitude | Above 20 km |
| Lead agency | Indian Air Force |
| Procurement model | Make-I |
The programme is expected to involve multiple Indian private aerospace companies competing to develop the technology.
What Are Stratospheric Airships?
AS-HAPS are high-altitude platforms designed to operate in the stratosphere for extended periods.
Their capabilities include:
- Persistent intelligence gathering.
- High-resolution optical surveillance.
- Electronic intelligence (ELINT).
- Long-range communications relay.
- Radar-based monitoring.
- Remote sensing missions.
Unlike conventional drones, these airships are designed to remain airborne for months, providing continuous monitoring over strategic regions.
Bridging the Gap Between Drones and Satellites
The new platforms are intended to complement existing surveillance assets.
| Platform | Typical Operating Altitude |
|---|---|
| High-altitude drones | Around 12 km |
| AS-HAPS airships | Above 20 km |
| Low-Earth orbit satellites | 500–2,000 km |
This positioning allows the airships to deliver persistent coverage while remaining easier to reposition than satellites.
Indigenous Technology Push
The government plans to maximize domestic development across the programme.
Key priorities include:
- Indigenous sensor development.
- Indian-made surveillance payloads.
- Domestic communication systems.
- Private-sector manufacturing.
- Reduced dependence on imported defence technology.
At least two development partners are expected to be shortlisted based on technical capability and financial strength.
Building on Earlier DRDO Success
The new programme follows earlier progress in indigenous high-altitude airship technology.
In May 2025, the Defence Research and Development Organisation (DRDO) successfully conducted the maiden flight trial of a stratospheric airship carrying an instrument payload to an altitude of nearly 17 kilometres from Madhya Pradesh. That demonstration validated several technologies required for future operational systems.
Strategic Advantages
The proposed airships could offer several operational benefits.
These include:
- Continuous border surveillance.
- Maritime monitoring.
- Early warning capabilities.
- Communications support during emergencies.
- Lower operating costs than satellites for persistent observation.
- Ability to reposition over areas of interest.
Their extended endurance makes them particularly suitable for monitoring sensitive border regions and strategic maritime corridors.
Global Race for High-Altitude Platforms
India joins several countries investing in similar technologies.
Current international efforts include:
- Europe’s EUROHAPS demonstration programme.
- Thales Alenia Space’s Stratobus project.
- U.S. high-altitude airship research.
- China’s reported investments in advanced high-altitude platforms.
Despite growing interest, operational deployment remains limited because of significant engineering and endurance challenges.
Outlook
India’s ₹15,000 crore AS-HAPS programme marks one of the country’s most ambitious defence aerospace initiatives. By combining long-endurance airships with indigenous surveillance payloads and communications systems, the project aims to strengthen India’s intelligence and reconnaissance capabilities while advancing self-reliance in strategic defence technologies. If successful, the programme could place India among a small group of nations with operational stratospheric surveillance platforms capable of persistent monitoring over vast areas.
What It Means for India’s Defence Sector
The project reflects India’s growing emphasis on developing sovereign surveillance capabilities that complement satellites, drones, and conventional aircraft. Stratospheric airships offer a unique balance of endurance, flexibility, and cost-effectiveness, enabling continuous monitoring without the limitations of orbital assets or fuel-dependent aircraft.
Beyond strengthening national security, the programme is expected to boost India’s domestic aerospace ecosystem by encouraging private-sector participation, indigenous sensor development, and advanced manufacturing. Successful execution could establish India as a global player in next-generation high-altitude surveillance technologies while supporting the broader goals of Aatmanirbhar Bharat in defence.
