India’s Defence Research and Development Organisation (DRDO) is developing the indigenous "Virupaksha" active electronically scanned array (AESA) radar for the Indian Air Force's Su-30MKI fighter fleet. Designed by the Electronics and Radar Development Establishment, the new radar will replace the aircraft's Russian-origin N011M Bars passive electronically scanned array system.
The Virupaksha radar features an antenna measuring approximately 950mm in diameter with roughly 2,400 gallium nitride transmit/receive modules, achieving its first power-on in February 2026. Officials stated the 4D radar can track up to 100 airborne targets simultaneously and guide six missiles against separate targets. DRDO is partnering with domestic firms including Astra Microwave and Bharat Electronics for development and production.
