NEW DELHI — June 02, 2026 : The Indian Air Force (IAF) is reportedly planning to equip its future fleet of Rafale fighter aircraft with advanced self-contained expendable Digital Radio Frequency Memory (DRFM) jammers, a next-generation electronic warfare capability designed to improve survivability against modern radar-guided missile threats.
According to recent defence industry reports, the proposed system is expected to function in a manner similar to Leonardo’s BriteCloud expendable active decoy, providing Rafale fighters with an additional defensive layer against sophisticated surface-to-air and air-to-air missile systems operating in contested environments.
The move reflects the IAF’s continuing focus on strengthening electronic warfare capabilities as modern air defence systems increasingly rely on advanced radar technologies capable of identifying, tracking, and engaging aircraft with greater accuracy than legacy systems.
Advanced Countermeasure Against Radar-Guided Threats
Traditional aircraft countermeasures such as chaff—small metallic strips dispersed in the air to confuse enemy radar—have long been used to counter radar-guided missiles. However, improvements in missile seeker technology and fire-control radars have reduced the effectiveness of conventional countermeasures against modern threats.
To address this challenge, air forces worldwide are increasingly adopting expendable active decoys based on DRFM technology. These systems are designed to deceive enemy radars by generating realistic electronic signatures rather than relying solely on reflected radar energy.
A DRFM jammer captures incoming radar signals, digitally stores and processes them, modifies their characteristics, and retransmits them back toward hostile radar systems with precise timing. Because the transmitted signal closely resembles the radar return from the actual aircraft, hostile systems may struggle to distinguish the false target from the fighter aircraft.
Unlike traditional onboard electronic warfare systems, expendable DRFM jammers function as independent off-board decoys once deployed.
Self-Contained and Expendable Design
Expendable DRFM jammers, also known as Expendable Active Decoys (EADs), are compact, battery-powered systems contained within a small cartridge. The system integrates a receiver, processor, transmitter, antenna, and power source into a single expendable package.
Typically designed to match standard flare cartridges, including 55mm countermeasure formats, these jammers can be launched through existing aircraft chaff and flare dispensers without requiring major structural modifications.
Once ejected, the decoy physically separates from the aircraft and independently emits electronic signals intended to mislead enemy radar systems. The “active” nature of the system refers to its ability to transmit off-board jamming signals rather than passively reflecting radar energy.
How the System Operates
The functioning of a self-contained DRFM jammer involves automated electronic responses triggered by incoming threats.
When the aircraft’s Radar Warning Receiver (RWR) detects an incoming radar-guided missile or hostile tracking radar, the onboard defensive suite can initiate deployment of the decoy. After ejection, the jammer activates and scans for radar emissions considered the highest operational priority.
Using a pre-programmed digital threat library, the system identifies and classifies incoming radar signals before employing DRFM technology to generate deceptive responses. The jammer receives the enemy radar signal, digitizes and alters it in real time to imitate the aircraft’s radar cross-section and electronic signature, then retransmits a modified signal back toward the threat.
As the decoy physically moves away from the aircraft, enemy radar systems and missile seekers may begin tracking the false electronic target instead of the fighter aircraft, increasing separation from the missile’s projected intercept point and improving survivability.
Operational Benefits for Future Rafale Aircraft
If integrated into future IAF Rafales, expendable DRFM jammers could provide multiple operational advantages.
One key benefit is enhanced protection against modern radar-guided missile systems, particularly those capable of rejecting traditional chaff countermeasures.
The system could also help counter missiles equipped with “home-on-jam” capability, which are designed to target the source of jamming emissions. Because expendable DRFM decoys separate physically from the aircraft, they may divert these missiles toward empty airspace instead of the fighter.
Another advantage lies in simplified aircraft integration. Since these decoys can fit within standard countermeasure dispensers, they require minimal airframe modification and can complement existing defensive systems.
The autonomous operation of the jammer may also reduce pilot workload during high-threat engagements. Once released, the system independently manages threat detection and electronic deception, allowing pilots to focus on aircraft maneuvering and mission execution.
Integration With Rafale’s Existing SPECTRA Suite
The Rafale already operates with the integrated SPECTRA (Self-Protection Equipment Countering Threats to Rafale Aircraft) electronic warfare suite, which combines radar warning receivers, missile warning systems, electronic support measures, and onboard jamming functions.
Any future expendable DRFM jammer would likely complement rather than replace the existing system.
In a combat environment, SPECTRA could detect, classify, and assess an incoming threat while the expendable decoy acts as a separate off-board electronic target intended to draw radar-guided missiles away from the aircraft.
Broader Evolution of IAF Electronic Decoys
The reported interest in expendable DRFM jammers comes as the IAF continues efforts to strengthen its electronic warfare capabilities against increasingly sophisticated surface-to-air and air-to-air missile threats.
The IAF has also been linked with plans to acquire advanced decoy systems such as the X-Guard Fibre-Optic Towed Decoy (FOTD), intended to improve aircraft survivability against radar-guided threats. Unlike expendable decoys, a fibre-optic towed decoy remains connected to the aircraft through a retractable cable and is designed to replicate the aircraft’s electronic and Doppler signature to mislead hostile radars and missile seekers.
If introduced in the future alongside self-contained expendable DRFM jammers, such systems could contribute to a multi-layered electronic warfare architecture aimed at improving the survivability of frontline combat aircraft operating in contested environments and against advanced air defence networks.
