The Indian Air Force (IAF) is advancing its Su-30MKI upgrade program with the introduction of the Virupaksha AESA radar, a Gallium Nitride (GaN)-based active electronically scanned array (AESA) radar designed to enhance combat effectiveness. This state-of-the-art radar, equipped with approximately 2600 Transmit/Receive Modules (TRM), promises superior range, reduced weight, optimized power consumption, enhanced cooling efficiency, and higher resolution than legacy systems.
To drive indigenous radar development, the Ministry of Defence (MoD) had released Express of Interest for potential Indian vendors to become the Development Cum Production Partners (DcPP) and receive the technology. These vendors will refine and produce the radar, with final contracts awarded to the lowest bid for mass production and integration.
Approved Indian Vendors
The following companies have been shortlisted based Technical Evaluation for next steps for DcPP selection :
- Astra Microwave Products Limited
- Hindustan Aeronautics Limited (HAL)
- ICOMM Tele Limited
- Larsen & Toubro Limited (L&T)
Significance of GaN-Based AESA Radar for Su-30MKI
The Virupaksha AESA radar represents a significant leap in airborne radar technology, providing the Su-30MKI with:
- Extended range for detecting and tracking aerial and ground targets
- Enhanced electronic warfare (EW) capabilities against enemy jamming
- Improved multi-target tracking with greater precision
- Lower power consumption, reducing aircraft thermal signature
- Better resolution, aiding in target identification and engagement
Next Steps: Competitive Bidding and Production
The lowest technically and commercially qualified bidders will secure mass production contracts, ensuring cost-effective and timely integration into the IAF’s Su-30MKI fleet.This initiative is a crucial step towards self-reliance in defense technology, strengthening India’s indigenous manufacturing ecosystem while enhancing combat readiness and operational superiority.
slow and consistent is our journey. it will take unprecedented pace within 5 years.
