Why in the News?

India and Indonesia have signed a defence agreement for the export of the Astra Mk-1 Beyond Visual Range Air-to-Air Missile (BVRAAM).

News in Brief
  • The deal marks the first-ever export of the indigenously developed Astra air-to-air missile by India.
  • The Astra Mk-1 missiles will be integrated with Indonesia’s Su-30 fighter aircraft.
  • The agreement strengthens India–Indonesia defence cooperation and boosts India’s defence exports under the Atmanirbhar Bharat initiative.
What is Astra Missile?
  • The Astra is an indigenously developed Beyond Visual Range Air-to-Air Missile (BVRAAM) designed and developed by the Defence Research and Development Organisation (DRDO).
  • It is primarily used by the Indian Air Force (IAF) and is also being integrated into the Indian Navy’s fighter aircraft.
  • The missile is designed to engage and destroy enemy aircraft at long distances, beyond the pilot’s visual range.

Key Features

  • Type- Beyond Visual Range Air-to-Air Missile (BVRAAM).
  • Developer- Defence Research and Development Organisation (DRDO).
  • Users- Indian Air Force (IAF) and Indian Navy.
  • Role- Engages and destroys enemy aircraft before they come within visual range.
  • Guidance System- Astra uses an Inertial Navigation System (INS) with mid-course datalink updates, an active radar seeker for terminal guidance, and a proximity fuse to destroy the target.
  • Capability- Can engage fighter aircraft, unmanned aerial vehicles (UAVs), bombers, and cruise missiles.
  • Performance- Features high manoeuvrability and all-weather operational capability.
  • Compatibility- Integrated with the Su-30 MKI and planned for LCA Tejas Mk1A, Rafale, and future Indian fighter aircraft.
Significance of the Astra Missile
  • Strengthens India’s air combat capability by enabling long-range engagement of enemy aircraft.
  • Promotes defence self-reliance through indigenous missile development under Atmanirbhar Bharat.
  • Reduces dependence on imported air-to-air missiles (Meteor Missile and Russian R-77 Missile), enhancing strategic autonomy.
  • Enhances India’s deterrence and national security with advanced Beyond Visual Range (BVR) capabilities.
  • Boosts India’s defence exports and global defence manufacturing reputation.

Beyond Visual Range Air-to-Air Missile (BVRAAM)

  • A Beyond Visual Range Air-to-Air Missile (BVRAAM) is a missile designed to engage and destroy enemy aircraft at distances beyond the pilot’s visual range.
  • It uses radar guidance, onboard navigation systems, and advanced seekers to detect, track, and intercept targets without requiring the pilot to see them directly.

Key Advantages of BVRAAM

  • Long-Range Engagement- Enables fighter aircraft to attack enemy targets from beyond visual range.
  • First-Shot Advantage – Allows pilots to strike before the adversary can respond, increasing combat effectiveness.
  • Enhanced Survivability- Reduces the need for close-range dogfights, thereby lowering the risk to the aircraft and pilot.
  • Network-Centric Warfare- Can receive mid-course target updates through data links, improving accuracy in coordinated operations.
  • All-Weather Capability- Operates effectively in day, night, and adverse weather conditions.
  • High Precision- Uses advanced radar seekers to accurately track and destroy fast-moving aerial targets.
Astra Missile Variants
  • Astra Mk-1
    • The Astra Mk-1 is the first operational variant of India’s indigenous BVRAAM and is currently in service with the Indian Air Force.
    • Key Features
      • Range: Approximately 80–110 km (head-on engagement).
      • Speed: Around Mach 4.5.
      • Operational Ceiling: Up to 20 km altitude.
      • Guidance: Equipped with an active radar seeker for terminal guidance.
      • Platforms: Integrated with the Su-30 MKI and planned for LCA Tejas Mk1A and Rafale aircraft.
  • Astra Mk-2
    • The Astra Mk-2 is an upgraded version under development, designed to provide greater range and improved combat capability.
  • Key Features
    • Expected Range: Approximately 160–200 km.
    • Improved Propulsion: Enhanced propulsion system for extended reach.
    • Advanced ECCM: Better Electronic Counter-Countermeasures (ECCM) to resist enemy electronic jamming.
    • Status: Received Acceptance of Necessity (AoN) from the Defence Acquisition Council (DAC).
    • Role: Intended for integration with India’s future fighter aircraft fleet.
  • Astra Mk-3 (Gandiva)
    • The Astra Mk-3, also known as Gandiva, is the most advanced variant currently under development.
    • Key Features
      • Expected Range: More than 350 km.
      • Propulsion: Powered by Solid Fuel Ducted Ramjet (SFDR) technology.
        • Solid Fuel Ducted Ramjet (SFDR)- A propulsion technology that provides continuous thrust throughout the missile’s flight, enabling longer range, higher speed, better end-game manoeuvrability, and a higher probability of target interception.
      • Performance: Continuous thrust throughout flight enables greater speed, manoeuvrability, and engagement range.
      • Status: Under development.
      • Significance: Expected to become India’s longest-range and most advanced Beyond Visual Range Air-to-Air Missile (BVRAAM).
