"Swayam Raksha Kavach Enhances TEJAS MK-1A with Indigenous Stealth Technology"
India's defence aviation has seen a significant advancement with the Defence Research and Development Organisation (DRDO) initiating flight tests of the sophisticated Electronic Warfare (EW) suite, 'Swayam Raksha Kavach,' on the TEJAS MK-1A Light Combat Aircraft. This development marks a milestone as it equips India with its first stealth-capable indigenous fighter.
The 'Swayam Raksha Kavach,' translated as Self-Defence Shield, is designed to render the TEJAS MK-1A nearly invisible to enemy radars and highly resilient to missile and electronic threats. As an indigenous innovation, this system provides Indian Air Force's leading fighters with a practical stealth ability, years ahead of the anticipated entry of the fifth-generation Advanced Medium Combat Aircraft (AMCA).
Constructed by Hindustan Aeronautics Limited (HAL), the TEJAS MK-1A stands as India's most advanced operational indigenous fighter. With the addition of Swayam Raksha Kavach, the aircraft's survivability, operational effectiveness, and electronic superiority in challenging airspaces are significantly enhanced.
The system consists of two crucial components:
| Component | Description |
|---|---|
| Radar Warning Receiver (RWR) | Detects and alerts pilots when enemy radar systems track the aircraft, enabling prompt evasive maneuvers. |
| Advanced Self-Protection Jammer (ASPJ) | Utilizes Digital Radio Frequency Memory (DRFM) technology to create deceptive signals and jamming waveforms, confusing enemy radar and missile systems. |
These technologies work collectively to significantly reduce the fighter's radar cross-section, providing an electronic form of stealth. Unlike traditional stealth aircraft that rely on physical design or radar-absorbent materials, Swayam Raksha Kavach achieves a dynamic stealth effect by electronically misleading enemy sensors in real-time.
As per DRDO officials, the production of the system began in 2021 at the Centre for Airborne Systems (CABS) in Bengaluru. With flight validations currently in progress, the system is expected to be fully operational by 2026. This timeline is set to establish TEJAS MK-1A as the most advanced indigenous combat aircraft ever deployed by the Indian Air Force.
The integration process also introduces cockpit upgrades and new avionics that coordinate threat detection, countermeasure activation, and pilot awareness into a unified adaptive system, representing a significant leap towards cognitive electronic warfare capabilities.
In September 2025, HAL secured governmental approval to produce an additional 97 TEJAS MK-1A aircraft, comprising 68 single-seat and 29 twin-seat models. These forthcoming jets will be equipped with factory-installed Swayam Raksha Kavach systems, ensuring future Indian Air Force squadrons are prepared for electronic warfare.
Experts in defence note that this initiative bridges India’s technological gap until the AMCA's arrival and highlights the nation's increasing confidence in its domestic aerospace innovations. This development also positions India among a select group of nations capable of integrating adaptive electronic warfare suites with indigenous fighter platforms.
With the integration of Swayam Raksha Kavach, India's TEJAS MK-1A not only gains enhanced survivability but also solidifies its status as a modern, stealth-enabled multirole fighter, reflecting India's progression towards self-reliance in defence technology.
