Electronic Warfare

1. Introduction

Electronic Warfare (EW) refers to the military use of the electromagnetic spectrum (EMS) to detect, deceive, disrupt, or deny the enemy’s electronic systems while protecting one’s own communication and surveillance networks. It involves the use of radio waves, radar signals, infrared, microwave, GPS, and other electromagnetic frequencies to gain a tactical or strategic advantage during military operations.

In modern warfare, advanced weapons, aircraft, missiles, drones, satellites, and communication systems rely heavily on the electromagnetic spectrum. Therefore, controlling this spectrum has become as important as controlling land, sea, air, and cyberspace. A nation that dominates the electromagnetic environment can significantly reduce the enemy’s operational capability without direct physical engagement. Electronic Warfare systems therefore play a critical role in modern military operations.

Unlike Cyber Warfare, which targets computer networks and digital data, Electronic Warfare targets the electromagnetic signals that enable communication, navigation, surveillance, and weapon guidance. In practice, both are often used together as part of hybrid warfare. These concepts are important for understanding Electronic Warfare Notes from a BPSC and UPSC examination perspective.

Importance of Electronic Warfare

• Enables real-time intelligence gathering by intercepting enemy radar and communication signals.
• Disrupts enemy communication, radar, GPS, and drone operations through jamming and deception.
• Protects friendly military assets from enemy electronic attacks.
• Enhances the effectiveness of air defence, precision-guided weapons, and unmanned systems.
• Acts as a force multiplier, allowing militaries to achieve operational superiority with minimal physical confrontation.

The growing importance of Electronic Warfare in India is linked to the increasing use of network-centric warfare, drones, precision-guided weapons, satellites, and advanced communication systems.

2. Major Techniques of Electronic Warfare

It is broadly classified into three components: Electronic Support (ES), Electronic Attack (EA), and Electronic Protection (EP). Together, they help a military detect enemy activities, disrupt adversary systems, and safeguard its own electronic assets. This framework is also described as Electronic Support Attack and Protection, and forms the core of modern Electronic Warfare systems.

(i) Electronic Support (ES)

Electronic Support involves detecting, intercepting, locating, and analysing enemy electromagnetic emissions such as radar and communication signals. It provides real-time intelligence on enemy positions, movements, and capabilities, enabling informed battlefield decisions.

Example: During the Russia–Ukraine War, both sides continuously intercepted radio communications and radar emissions to locate enemy artillery and command posts, improving the accuracy of counter-attacks.

(ii) Electronic Attack (EA)

Electronic Attack aims to degrade, disrupt, deceive, or destroy enemy electronic systems through techniques such as radar jamming, GPS spoofing, communication interference, and anti-radiation missiles. It can render enemy aircraft, drones, missiles, and air-defence systems ineffective without physically destroying them.

Examples:

• In the Russia–Ukraine War, extensive GPS jamming disrupted drone navigation and precision-guided weapons.
• During the Israel–Iran confrontation (2024–25), electronic jamming and spoofing were widely used to counter drones and guided missiles.
• During Operation Sindoor (2025), India reportedly employed electronic warfare systems to suppress enemy radar and communication networks while neutralising drone threats.

(iii) Electronic Protection (EP)

Electronic Protection comprises measures taken to secure friendly communication, radar, navigation, and weapon systems from enemy electronic attacks. It includes frequency hopping, signal encryption, anti-jamming technologies, electromagnetic shielding, and secure communication networks, ensuring uninterrupted military operations even in a contested electromagnetic environment.

Example: Modern fighter aircraft such as the Rafale and LCA Tejas Mk-1A are equipped with advanced electronic warfare suites that detect hostile radar signals, issue threat warnings, and deploy electronic countermeasures to enhance aircraft survivability.

3. Electronic Warfare in Recent Global Conflicts

Recent conflicts have demonstrated that Electronic Warfare (EW) has become indispensable in modern military operations. Control over the electromagnetic spectrum is now as critical as superiority in land, air, sea, and cyberspace. The following conflicts provide important examples for Electronic Warfare Notes and demonstrate the growing operational importance of Electronic Warfare systems.

Russia–Ukraine War (2022–Present)

• Widely regarded as the largest electronic warfare battlefield since World War II.
• Russia deployed advanced EW systems such as Krasukha-4, Zhitel, Tirada-2, and Borisoglebsk-2 to jam Ukrainian radars, GPS signals, and military communications.
• Both sides extensively used GPS jamming and spoofing to disrupt drones, precision-guided missiles, and navigation systems.
• Russia has also targeted Starlink satellite communications, attempting to disrupt Ukrainian drone operations through electronic jamming.

Israel–Hamas Conflict (2023–Present)

• Israel employed sophisticated electronic warfare to support the Iron Dome and other air-defence systems against rockets and drones.
• Electronic intelligence (ELINT) was extensively used to detect militant communications and locate launch sites.
• Both sides attempted to interfere with drone control links and communication networks, highlighting the growing importance of EW in urban warfare.

Israel–Iran Conflict (2024–25)

• Both countries relied heavily on GPS jamming, spoofing, and electronic countermeasures to defend against drones and missile attacks.
• Electronic warfare was used to degrade enemy navigation systems and protect strategic installations.
• The conflict demonstrated how electromagnetic spectrum dominance is increasingly essential for missile defence and unmanned systems.

India–Pakistan: Operation Sindoor (2025)

• During Operation Sindoor, India integrated electronic warfare with precision air strikes and air-defence operations.
• Electronic warfare systems were reportedly used to jam enemy communication links, suppress radar systems, and neutralise hostile drones, improving the effectiveness and survivability of Indian aircraft.
• The operation highlighted India’s growing emphasis on network-centric and spectrum-centric warfare.

The experience of Operation Sindoor is particularly relevant to Electronic Warfare in India, demonstrating the increasing importance of indigenous Electronic Warfare systems for integrated military operations.
