The Radio Electronic Technologies concern provided the Prospective Airborne Complex of Frontline Aviation (PAC FA) T-50 with the first batch of Himalayas electronic warfare systems.

“We are currently testing it,” General Director Nikolay Kolesov told TASS.
“T-50 prototypes are already equipped with the Himalayas onboard defense system. The system is used in plane tests,” Kolesov said.
The unique air system increases fighter jet’s jamming resistance and damage tolerance, as well as neutralizes enemy’s signature control systems. It also helps decrease aggregate weight of the PAC FA.

The Himalayas are integrated into the jet fighter system to the extent it functions as a so-called smart cover. “In other words, we are not producing some separate blocks, but parts of a plane with add-in electronic devices,” Kolesov stressed when talking about fifth-generation jet fighters’ electronic warfare characteristics.

The Himalayas EW system was developed by the Kaluga Scientific Research and Radio Technology Institute and is manufactured at the Signal radioplant in Stavropol. They are both part of the Radio Electronic Technologies concern.
The concern is Russia's largest electronic industry holding company. It was established back in 2009 and is now part of the Rostec State Corporation. It specializes in development and production of systems and commercial avionics, position-radar station of air basing, identification and electronic warfare systems, measuring apparatus for various purposes. The concern includes 97 scientific research institutes, a development laboratory and production facilities.
