The new X-band active phased array radar has been installed on the third prototype of the T-50 fighter and showed a stable and effective performance comparable with the most advanced existing radar systems.
The radar has been developed by the Moscow-based Tikhomirov Scientific Research Institute of Instrument Design using elements of nanotechnology.
It has an extended target acquisition range, works simultaneously in “air-to-air” and “air-to-ground” modes, allows attacking multiple targets, and provides electronic countermeasures capabilities.
The T-50, also known as project PAK-FA, first flew in January 2010 and was first publicly revealed at the Moscow Air Show in 2011.
At present, three T-50 prototypes are being tested under a PAK-FA test and development program while a fourth plane is expected to join the program this year.
The Russian Defense Ministry is planning to purchase the first 10 evaluation example aircraft after 2012 and then 60 production standard aircraft after 2015.
