India has decided to design and develop a long-range dual-band infrared imaging search and track system (IRST) for Su-30MKIs. IRST will strengthen the capabilities of the aircraft in detecting ultra-stealthy aircraft like the F-22 and Chengdu J-20. The system will be able to operate in day and night conditions and will substantially enhance the capabilities of the aircraft.

The Indian defence ministry wants at least 40% domestically-produced content in the system which will be manufactured in any Indian facility. The system will be integrated into India's frontline aircraft without making any structural changes.

The IRST system is a crucial part of the advanced fifth-generation aircraft as it plays a critical role in detecting heat sinking missiles and locate and destroy enemy targets in radar denied environment.
