Indigenous Surveillance Airships to Strengthen India’s Border Monitoring

India has initiated the Airship-based High Altitude Pseudo Satellite (AS-HAPS) programme for indigenous stratospheric airships designed for long-endurance surveillance missions. The programme has an estimated outlay of ₹15,000 crore and is linked to border monitoring, intelligence, surveillance and reconnaissance (ISR), and long-range communications.

High-Altitude Pseudo Satellites

High Altitude Pseudo Satellites (HAPS) are lighter-than-air or fixed-wing platforms that operate in the stratosphere, usually at altitudes of 20 km to 30 km. These platforms remain below low-Earth orbit satellites, which generally operate between 500 km and 2,000 km, and above many high-altitude drones that fly at around 12 km.

Programme Structure and Procurement

The Directorate of Operations (Remote) of the Indian Air Force is steering the project under the Make-I procurement framework. Under this framework, the government can fund up to 70% of development costs for selected private partners, and the programme seeks indigenous development of airship systems and payload integration.

Operational Features and Payloads

The airships are designed to remain aloft for months and to be steerable in flight. They can carry optical surveillance systems, electronic intelligence payloads, radars, electro-optical systems, and communication equipment for persistent observation over fixed or mobile areas.

Important Facts for Exams

• The Defence Acquisition Council approved the procurement of High Altitude Pseudo Satellites for the Indian Air Force in February 2026.
• The Defence Research and Development Organisation demonstrated the technology in May 2025 with a payload-bearing prototype at about 17 km altitude over Madhya Pradesh.
• HAPS platforms operate in the stratosphere and are used for persistent surveillance and communications.
• The Make-I category under India’s defence procurement system allows government funding for prototype development with private participation.

ISR stands for intelligence, surveillance and reconnaissance, a standard military term used for information collection through sensors and communication systems. The AS-HAPS programme is part of India’s wider effort to develop indigenous aerospace and defence technologies for border security and strategic monitoring.
