In 2002, it won a Russian government tender for training aircraft and in 2009 the aircraft entered service with the Russian Air Force.  As an advanced training aircraft, the Yak-130 is able to replicate the characteristics of several 4+ generation fighters as well as the fifth-generation Sukhoi Su-57.  It can also perform light-attack and reconnaissance duties, carrying a combat load of 3,000 kg.
