Chinese Firm Unveils New Sensors For J-20, J-31

A privately-owned Chinese sensor company has unveiled a suite of air-to-air and air-to-ground sensors in development for the latest Chinese and Russian fighters.

Wang Yanyong, technical director for Beijing A-Star Science and Technology, confirms that two systems – the EOTS-89 electro-optical targeting system (EOTS) and the EORD-31 infrared search and track (IRST) – are in development for China’s J-20 and J-31 fighters.

Marketing brochures on A-Star’s booth suggest that the J-20 could use the passive sensors to detect and aim missiles against the Northrop Grumman B-2 bomber and Lockheed Martin F-22 fighter, even while its radar is being being jammed by a Boeing EA-18G Growler. It lists detection ranges for the B-2 at 150km and for the F-22 at up to 110km.

Both systems have completed ground testing in a laboratory, and are now ready to enter flight testing, he says. Chinese combat aircraft manufacturer AVIC is considering integrating the sensors on a testbed aircraft, then could decide to test them on the J-20 and J-31, he says. Operational status is at least a year away for both sensors and possibly longer, Yanyong adds.



A-Star exhibited the systems at MAKS in hopes of attracting buyers from Russian and Commonwealth of Independent States countries, he says.
