The Yak-130, however, was said to be superior as it could serve the dual role of a trainer and combat jet. On 10 April 2002, it was announced that Yak-130 had been chosen as the winner of the tender for trainer aircraft for basic and advanced pilot training, beating the MiG-AT. By then, the Russian Air Force had ordered 10 Yak-130s, and the total cost of research and development, which included the construction and testing of the four pre-production aircraft, had amounted to some $200 million, 84% of which was financed by Yakovlev and the rest by the Russian government. However, it was reported that as much as $500 million had been spent in as early as 1996. Plans to develop a light-attack aircraft based on the Yak-130 came to a halt in the late 2011. Dubbed Yak-131, the aircraft failed to meet critical pilot safety requirements put forward by the Russian Air Force. The air force had instead shifted focus to a replacement based on the Sukhoi Su-25, which was slated to enter service by 2020. Design Yak-130 is an advanced pilot training aircraft, able to replicate characteristics of Russian 4th and 5th generation fighters. This is possible through the use of open architecture digital avionics compliant with a 1553 Databus, a full digital glass cockpit, four-channel digital Fly-By-Wire System (FBWS) and Instructor controlled and variable FBWS handling characteristics and embedded simulation. The type also has a Head-up display (HUD) and a Helmet-Mounted-Sighting-System (HMSS), with a double GPS/GLONASS receiver updating an Inertial Reference System (IRS) for highly accurate navigation and precision targeting. The developer estimates that the plane can cover up to 80% of the entire pilot flight training program. In addition to its training role, the aircraft is capable of fulfilling Light Attack and Reconnaissance duties. It can carry a combat load of , consisting of various guided and un-guided weapons, auxiliary fuel tanks and electronic pods. According to its chief designer Konstantin Popovich, during a testing phase that ended in December 2009, the plane was tested with "all airborne weapons with a weight of up to 500 kg that are in service in the Russian Air Force". Yak-130 has nine hard points: two wingtip, six under-wing and one under-fuselage. The aircraft's twin engines are mounted under extended wing roots, which reach as far forward as the windscreen.
