The Yak-130 lost the recent tender of the Russian air force on a prospective strike aircraft. According to a source in the Russian aviation industry, "requirements primarily for booking and defence systems was too high for the plane light class". The tender was won by the deep draft of the modernized su-25 weight of 19.5 tons, which is almost two times higher than that of the Yak-130.
However, Irkut continues work on single combat version of the aircraft, relying on export customers, as well as the fact that the Russian air force will purchase a light strike aircraft. Single seat modification of the Yak-130 has an index of the Yak-133, were previously known double Yak-131 and supersonic Yak-135. The first prototype of the Yak-133 will be built in 2014
Changes to the air-frame will be insignificant, the rear pilot's seat will be replaced by an additional fuel tank and other accessories. The engines will be increased capacity - up to 27.45 kN each, compared with the current thrust of 24.51 kN.
On impact modification are also installed radar and electro-optical sighting system. According to Konstantin Popovich, it is considered as a variant of the onboard radar and radar in pod. To receive proposals on three Russian companies: "Corporation Fazotron-NIIR", "NIIP. Tikhomirov "Holding and" Leninist ".
FC-130 radar development "Phazotron" (the index to remain unchanged in spite of the modification) may be millimeter range to find land targets, multifunction radar 30 mm range with slot antenna or radar 30mm range AESA. The last option is the most perfect and most expensive: AESA radar can cost about 10% of the total cost of the aircraft, twice the cost of other systems.
Suspended optoelectronic container for the Yak-130 is being developed on the basis of the CPR SPC modifications created for Indian MiG-29K.
These new sensors allow the attack modification of the Yak-130 used ant-radar / anti-ship missile X-31 and the new Russian missiles Kh-38 with different variants of the guidance, and guided bombs. The weapon of class "air-to-air" will include medium-range missiles R-77m. Popovic stressed, stability and handling of the Yak-130 allow the use of such weapons.
So Yak 135 - supersonic and with AAM with range 110km and relatively cheap in maintenance. Me thinks good prospects on international market and for RuAF not bad choice either for homeland defense.
