The Ministry of Defence has released a Request for Proposal (RFP) to equip 258 Su-30MKI fighter jets of the Indian Air Force (IAF) with new, domestically developed anti-jamming and anti-spoofing navigation systems.
This significant upgrade aims to fortify the aerial fleet against modern electronic warfare tactics, ensuring that the IAF's primary combat aircraft remain highly resilient in hostile environments.
This initiative focuses on integrating advanced, multi-constellation global positioning system (GPS) antennas across the Su-30MKI fleet.
With over 250 of these jets currently serving as the cornerstone of India's air combat strength, protecting their navigation capabilities is a high priority.
The upgrade is largely driven by the increasing prevalence of electronic warfare in recent global conflicts, where adversaries frequently deploy sophisticated techniques to jam or manipulate satellite signals.
According to the official RFP, the new indigenous technology will guarantee accurate positioning and continuous navigation even when operating in intensely contested airspace.
When hostile forces attempt to block or spoof essential satellite data, these upgraded systems will allow pilots to maintain their situational awareness. Such enhancements are critical for ensuring high mission survival rates and uninterrupted operations during a conflict.
A key feature of the proposed antenna is its ability to simultaneously draw data from multiple global satellite networks.
It will support India’s own NavIC system, along with the American GPS, Russian GLONASS, European Galileo, Chinese BeiDou, and the GAGAN augmentation network.
Defence experts note that combining these various navigation sources creates crucial redundancy; if one or more satellite networks are compromised by enemy interference, the aircraft will still have reliable guidance data to complete its mission.
The tender outlines strict requirements for electronic protection.
The upgraded antennas must be highly resilient, possessing the capacity to counter single-source jamming by up to 85 decibels, and handle simultaneous interference from multiple sources by up to 80 decibels.
These robust specifications will enable the Sukhoi fighters to execute precision strikes and operate seamlessly, even when subjected to heavy enemy electronic attacks aimed at blinding their navigation systems.
Furthermore, the new equipment is mandated to perform flawlessly across the fighter's demanding flight profile.
It must maintain stability and reliability at extreme altitudes up to 21 kilometres and at supersonic speeds reaching Mach 1.5.
Additionally, the system must endure immense gravitational forces, functioning perfectly during aggressive combat manoeuvres that generate acceleration loads between -2 g and +9 g.
The chosen Indian manufacturer will be tasked with delivering a total of 300 antenna systems, supplemented by 50 field-level and 10 base-level testing units.
Before these systems are rolled out to the broader fleet, comprehensive certification and validation trials will be conducted on two designated Su-30MKI aircraft to ensure strict compliance with safety and performance standards.
Beyond the hardware, the project mandates comprehensive installation support for all designated aircraft.
The contract also involves thorough training for IAF personnel at the 9 TETTRA School. This educational component ensures that the Indian Air Force can independently manage, operate, and maintain the advanced navigation equipment for years to come.
To swiftly counter rapidly evolving electronic threats in the region, the Ministry of Defence has stipulated a strict 24-month timeline for the project's completion, starting from the day the contract is signed.
This rapid induction schedule underscores the urgency of adapting the IAF’s frontline fighters to the realities of modern, technology-driven warfare.
