AS-HAPS Approved by DAC: High Altitude Pseudo Satellites for Indian Air Force Explained

Leave a Comment / Daily Current Affairs, Defence Current Affairs /

Why in News?

e Defence Acquisition Council (DAC) has approved the induction of Airship-Based High Altitude Pseudo Satellites (AS-HAPS) for the Indian Air Force.

as haps

Key Highlights:

AS-HAPS (Airship-Based High Altitude Pseudo Satellites) operate in the stratosphere, bridging the gap between UAVs and satellites. They are

  • Solar-powered, unmanned aerial platforms
  • Operate in the stratosphere (18–25 km above Earth)

They act as an intermediate system between:

  • UAVs (drones) – lower altitude, short endurance
  • Satellites – high altitude, expensive

Key Advantages:

  • Long endurance (can stay operational for extended periods)
  • Cost-effective compared to satellites

Pralay Missile:

Pralay (meaning “Apocalypse”) is India’s first indigenously developed short-range, surface-to-surface tactical ballistic missile designed for conventional strikes.

It fills a critical gap in India’s arsenal between long-range strategic nuclear missiles (Agni series) and short-range battlefield rockets (Pinaka)

  • Range: 150 km to 500 km.
  • Speed: Capable of reaching terminal speeds of Mach 6.1.
  • Payload: Can carry conventional warheads weighing between 500 kg and 1,000 kg.
