The prevalent use of drones in modern warfare is a test of India’s Counter-Drone Preparedness. Read here to understand better about the nuances of the drone threat to a country’s security.

The Union Government’s warning regarding possible rogue drone attacks on critical installations along India’s borders highlights a rapidly evolving security challenge.

Recent conflicts in Ukraine, West Asia, the Caucasus, and the Red Sea have demonstrated that inexpensive commercial drones, First-Person View (FPV) drones, loitering munitions, and AI-enabled unmanned systems are fundamentally transforming the nature of warfare.

The traditional dominance of tanks, artillery, and manned aircraft is increasingly being challenged by small, affordable, and highly adaptable drones capable of carrying out surveillance, precision strikes, electronic warfare, and logistics missions.

Consequently, India is accelerating the deployment of advanced counter-drone systems to safeguard vital national assets, border infrastructure, military installations, and civilian facilities.

Threat of Rogue Drones

A rogue drone refers to an unmanned aerial vehicle (UAV) operating without authorisation or employed for hostile purposes.

These may be used for:

• Surveillance and espionage
• Cross-border infiltration
• Arms and narcotics smuggling
• Precision strikes on strategic targets
• Terrorist attacks
• Disruption of critical infrastructure

The increasing availability of commercial drone technology has significantly lowered the barrier to acquiring sophisticated aerial capabilities.

Drones in Modern Warfare

Cost-Effectiveness and Affordability

One of the most important reasons behind the growing use of drones is their exceptional cost-effectiveness.

Comparative Costs

Platform	Approximate Cost
Main Battle Tank	Millions of dollars
Fighter Aircraft	Tens of millions of dollars
FPV Drone	A few hundred dollars
Loitering Munition	Significantly cheaper than missiles

A low-cost drone can destroy equipment worth millions, creating a highly asymmetric battlefield advantage.

Example: In the Russia-Ukraine conflict, commercially modified FPV drones have successfully destroyed tanks, artillery systems, and command posts at a fraction of the cost of conventional weaponry.

Multi-Role Battlefield Capability

Modern drones are no longer limited to reconnaissance.

They perform:

Intelligence, Surveillance and Reconnaissance (ISR)

• Real-time battlefield monitoring
• Target identification
• Border surveillance

Precision Strike Missions

• Destruction of armoured vehicles
• Attacks on ammunition depots
• Neutralisation of command centres

Logistics and Supply

• Medical supplies
• Food and emergency equipment

Electronic Warfare

• Signal interception
• Communication disruption
• Electronic intelligence gathering

Operational Adaptability

Drones can be:

• Rapidly manufactured
• Easily modified
• Deployed in large numbers

Unlike traditional military systems requiring years of development, drone technologies evolve within months.

This adaptability provides militaries and non-state actors with unprecedented operational flexibility.

FPV Drones and Loitering Munitions

First-Person View (FPV) Drones

FPV drones allow operators to guide the platform through onboard cameras in real time.

Characteristics:

• Extremely accurate targeting
• Low cost
• Difficult to detect
• Highly maneuverable

Loitering Munitions

Often called “kamikaze drones,” they:

• Search for targets autonomously
• Loiter over battlefields
• Dive into selected targets

Examples include:

• Switchblade
• Lancet
• Harop

These systems blur the distinction between drones and missiles.

Electronic Warfare Resilience

Modern battlefields feature extensive electronic warfare (EW).

Traditionally, drones were vulnerable to:

• Jamming
• Spoofing
• Signal interception

However, new technologies include:

• Fibre-optic guided drones
• Autonomous navigation systems
• AI-assisted targeting
• Anti-jamming communication systems

These innovations significantly enhance survivability.

Persistent Surveillance and Transparent Battlefields

Drone warfare has eliminated many traditional battlefield “blind spots.”

Consequences

• Continuous monitoring of troop movements
• Real-time targeting capability
• Reduced concealment opportunities
• Vulnerability of rear logistics bases

The battlefield has become increasingly transparent, where detection often leads directly to engagement.

Concerns Associated with Drone Warfare

Lower Barrier to Conflict

The affordability of drones allows:

• Terrorist organizations
• Insurgent groups
• Criminal syndicates
• Non-state actors

to access military-grade capabilities previously available only to states.

This intensifies asymmetric warfare.

Escalation Risks

Drone attacks are:

• Relatively cheap
• Politically less risky
• Easily deniable

This lowers the threshold for military escalation and encourages prolonged hybrid warfare.

Threat to Critical Infrastructure

Drones pose a direct threat to:

• Airports
• Ports
• Refineries
• Nuclear facilities
• Military bases
• Power grids
• Communication networks

Even small drones can cause significant disruption if employed strategically.

Swarm Warfare Challenge

One of the most difficult emerging threats is drone swarming.

• Multiple drones attack simultaneously.
• Defences become saturated.
• Traditional missile systems become economically inefficient.

A swarm of inexpensive drones can overwhelm sophisticated air-defence networks.

Detection and Interception Difficulties

Small drones:

• Fly at low altitudes
• Have minimal radar signatures
• Can operate silently
• Blend with civilian air traffic

Conventional air defence systems were not designed to detect such threats.

Ethical and Legal Challenges

Drone warfare raises important questions regarding:

• Accountability
• Civilian casualties
• Autonomous weapons
• Rules of engagement
• International humanitarian law

Current international legal frameworks have not fully adapted to these technological developments.
