India’s Air Defence Shield
Context: India's Air Defence Shield proved its effectiveness during Operation Sindoor, where IACCS played a central role in real-time aerial threat response against Pakistan.
Important Pointers:
IACCS (Integrated Air Command and Control System) – IAF:
► Developed by BEL (Bharat Electronics Limited) ► Automated command & control integrating data from radars, sensors, and communication nodes ► Offers real-time updates and situational awareness ► Enables central control + decentralized execution ► Helps in quick threat identification & response ► Uses overlapping radar/radio data for effective airspace management ► Future-ready as its integration with AI and modern tech is planned
Akashteer – Indian Army:
► Developed by BEL ► Controls and monitors low-level battle airspace ► Contract worth ₹1,982 crore signed in March 2023 ► Coordinates ground-based air defence weapons ► Undergoing integration with IACCS for joint operations
Multi-Layered Air Defense Structure:
Layer
System/Weapon
Description
Layer 1
Counter-Drone Systems
Neutralizes small, low-flying UAVs; increasingly critical in modern asymmetric warfare.
MANPADS (Man-Portable Air Defense Systems)
Lightweight, shoulder-fired missiles are effective against low-flying aircraft and helicopters.
Layer 2
Point Air Defense
Protects specific high-value assets (e.g., bases, installations); includes guns and SAMs.
Short-Range Surface-to-Air Missiles (SRSAMs)
Intercepts threats within a short range (~20–30 km); fast-reaction time against quick aerial attacks.
Layer 3
Medium-Range Surface-to-Air Missiles (MRSAMs)
Provides area defense with interception range up to ~70 km; capable against aircraft & cruise missiles.
Layer 4
Long-Range Surface-to-Air Missiles (LRSAMs)
Capable of engaging threats at ranges >100 km; forms the outermost defensive layer.
