Concern Radio-Electronic Technologies (KRET), part of Russia’s State Corporation Rostec, is ready to provide new Irbis-E radar control systems for SU-35s that will be exported from Russia, according to a company news release.

“We are ready to equip these Su-35s with a complete set of avionics including airborne radars, control systems, all sensors and a new EW system,” said Vladimir Mikheev, advisor to first deputy CEO of KRET.

China signed an agreement to purchase 24 multirole Su-35 fighters last year for $2 billion, or about $83 million per aircraft.

The fighters will receive the newest Irbis-E passive phased array radar systems, providing detection, tracking and coordinate measurement of air, ground, and surface targets, day-and-night, in all weather conditions in the presence of natural noise and jamming, according to KRET. The fighters also get the RSUO weapon management system, which has special-purpose hardware to identify the condition of weapons aboard the aircraft and control their loading management. Other systems include an electronic countermeasures release system for protection against air-to-air and surface-to-air guided missiles through expendable countermeasures, HOTAS controls, and a SAP active jamming station.

КRET is Russia’s largest instrument engineering holding, and was established in 2009. The company develops and produces avionics for commercial and military aircraft, electronic warfare (EW), Identification Friend or Foe systems (IFF), measuring equipment for various purposes (ME), electrical connectors and cable systems, various household appliances, and medical devices. The concern includes about 54,000 employees working in more than 92 research institutes, design bureaus and production plants located in 29 regions of the Russian Federation.
