What are ASAT Weapons?
Anti-Satellite (ASAT) weapons are systems designed to disable, damage, or destroy satellites in Earth’s orbit, thereby degrading an adversary’s space-based communication, navigation, surveillance, and early-warning capabilities.
Why are ASAT Weapons Important?
Modern warfare depends heavily on satellites for:
Communication (C4ISR)
Navigation (GPS/NavIC)
Missile warning & tracking
Intelligence & surveillance
➡️ Destroying satellites can blind, disrupt, or paralyse military operations.
Types of ASAT Weapons
1️⃣ Kinetic-Kill ASAT
Destroys satellite by direct collision
Creates space debris
Example: India’s Mission Shakti
2️⃣ Non-Kinetic ASAT
Electronic warfare (jamming signals)
Cyber attacks on satellite control systems
Directed energy weapons (lasers, microwaves)
Less debris-creating
Methods of ASAT Attack
Direct-ascent missiles (from Earth)
Co-orbital satellites (orbit near target)
Ground-based lasers
Cyber & electronic attacks
India’s ASAT Capability – Mission Shakti
Year: 2019
Conducted by: DRDO
Target: Indian satellite in Low Earth Orbit (LEO)
Significance:
India became the 4th country with proven ASAT capability (after USA, Russia, China)
Demonstrated indigenous missile defence technology
No violation of international law
📌 Debris concern addressed by low-altitude interception.
ASAT & International Law
Outer Space Treaty (1967):
Prohibits weapons of mass destruction in space
Does not ban ASAT weapons
Growing calls for:
Space arms control
Prevention of weaponisation of outer space
Strategic Significance for India
Strengthens deterrence
Protects national space assets
Enhances bargaining power in global forums
Supports space security posture
Complements Defence Space Agency (DSA)
Concerns & Challenges
Space debris threat
Escalation risks
Lack of global norms
Militarisation of outer space
India’s Position on ASAT
Committed to peaceful use of outer space
Supports no first placement of weapons in space
Advocates responsible behaviour & sustainability
