New Delhi: The Indian Army Anti-Drone System has taken a significant step forward with the patenting of a new active protection concept designed to defend tanks against drone attacks.
The patented system uses a unique counter-rotating blade mechanism mounted above a tank turret to physically intercept incoming aerial threats.
The innovation comes at a time when drone warfare is rapidly changing battlefields across the world, especially in conflicts where low-cost FPV drones and loitering munitions have become major threats to armored vehicles.
What Is the New Indian Army Anti-Drone System?
According to the patent details, the Indian Army has developed an active protective canopy consisting of two layers of rotating blades mounted on a central mast above the tank turret.
The blades rotate in opposite directions, creating a moving shield over the most vulnerable upper sections of the tank.
Key Features
- Dual-layer counter-rotating blade structure.
- Mounted above the tank turret.
- Powered by a dedicated motor and transmission system.
- Designed to physically damage, deflect, or trap incoming aerial threats.
- Provides protection against top-attack drones and drone-dropped explosives.
- Allows tanks to maintain mobility without heavy additional armor.

Why Is This Patent Important?
Modern battlefields have shown that tanks are increasingly vulnerable from above.
Recent conflicts, particularly the Russia-Ukraine war, have demonstrated how inexpensive FPV drones and loitering munitions can destroy expensive armored vehicles by targeting weak roof armor. Military planners worldwide are therefore searching for new ways to improve tank survivability.
The Indian Army’s new concept focuses on:
- Active physical protection.
- Low-cost interception.
- Protection against swarm and FPV drone attacks.
- Improved battlefield survivability.
How Does the Indian Army Anti-Drone System Work?
The patented design creates what can be described as a rotating protective umbrella over the tank.
Working Principle
- Incoming drones approach from above.
- Counter-rotating blades generate strong airflow and physical impact.
- Drones, loitering munitions, or explosive payloads may be struck, damaged, or diverted before reaching the tank.
- The system aims to prevent explosives from detonating directly on critical areas such as:
- Engine compartment
- Turret roof
- Crew hatches
- Fire-control equipment
How Is It Different from Existing Tank Protection?
Many armies currently use:
- Cage armor (cope cages)
- Slat armor
- Mesh screens
- Passive roof protection
However, these systems are static and often increase vehicle weight while reducing mobility. The Indian Army’s patented solution is different because it is an active mechanical defense system rather than a passive protective structure.
Comparison
| Feature | Traditional Cage Armor | Indian Army Blade Shield |
| Protection Type | Passive | Active |
| Mobility Impact | Moderate to High | Potentially Lower |
| Moving Components | No | Yes |
| Drone Interception | Limited | Designed for Active Interception |
| Top-Attack Defense | Partial | Primary Objective |
