The Indian Air Force (IAF) has taken a significant step towards enhancing the survivability and electronic warfare (EW) capabilities of its fleet by releasing a Request for Information (RFI) for the acquisition of 100 Advanced Self-Protection Jammer (ASPJ) pods, specifically designed for its frontline Su-30MKI fighter jets. This initiative is part of the Super Sukhoi modernization program aimed at transforming the Su-30MKI into a more formidable platform in the face of evolving aerial threats.
The ASPJ pods will leverage Digital Radio Frequency Memory (DRFM) technology. This state-of-the-art approach involves receiving, analyzing, and retransmitting modified radar signals, enabling the system to effectively confuse enemy sensors and missiles. Unlike conventional noise-based jammers, which primarily generate interference, these advanced jammers can create false radar targets and perform sophisticated maneuvers such as range and velocity gate pull-off. This increases the aircraft’s chances of survival in high-threat scenarios, providing a multi-directional shield against incoming threats.
IAF officials emphasize that the new system will offer 360-degree protection against radar-guided missile threats from any angle. The jammers will be equipped with Gallium Nitride (GaN)-based Active Electronically Scanned Array (AESA) transmitters. These transmitters are known for their high power efficiency, compact design, and rapid electronic beam steering capabilities. The high Effective Radiated Power (ERP) will enhance the jammers’ ability to counteract enemy surveillance and fire-control radars effectively.
The procurement of the ASPJ pods is integral to the larger Super Sukhoi upgrade, which is set to evolve the Su-30MKI fleet into a more advanced 4.5-generation air superiority platform. In addition to the ASPJ system, the upgrade will see the replacement of the aircraft’s existing N011M Bars Passive Electronically Scanned Array (PESA) radar with the DRDO’s GaN-based AESA radar known as ‘Virupaksha’. The new radar promises longer detection ranges, improved tracking abilities, and resilience against jamming.
The comprehensive modernization program will also incorporate a new all-digital glass cockpit, upgraded Radar Warning Receivers, and the integration of indigenous Beyond Visual Range (BVR) missiles and precision-guided munitions.
The ASPJ pods are designed to work alongside a new Defensive Aids System (DAS), creating a cohesive electronic warfare suite that is expected to greatly enhance mission effectiveness and survivability in contested airspaces.
In alignment with the Make in India initiative, the IAF is focusing on domestic production and technology transfer for this project. The RFI indicates potential collaboration between the Defence Research and Development Organisation’s (DRDO) Defence Avionics Research Establishment (DARE) and Bharat Electronics Limited (BEL) for the indigenously designed and manufactured ASPJ systems.
This collaboration is anticipated to strengthen India’s self-reliance in critical electronic warfare technologies, foster cost-effective maintenance solutions, and lay the groundwork for similar systems in future aircraft, such as the Tejas Mk-1A, Tejas Mk-2, and the Advanced Medium Combat Aircraft (AMCA).
The integration of the ASPJ and the Super Sukhoi upgrade is projected to extend the operational life of the Su-30MKI fleet by almost two decades. The incorporation of DRFM and GaN-based systems is set to modernize the aircraft significantly, bringing India’s air combat capabilities in line with international standards.
By combining indigenous innovation with advanced technological enhancements, the ASPJ initiative represents a pivotal advancement in India’s ongoing efforts to achieve air superiority and excel in electronic warfare capacities in the years to come.
