Yakovlev Yak-130 (Russia). First flight: 25 April 1996. (Wiki)

Development of Yak-UTS started in 1991 and the design was completed in September 1993. The same year, Yakovlev entered an agreement with the Italian company Aermacchi to work together on the plane, which now became Yak/AEM-130. The Yak-130 version was to be offered for the Russian and the M-346 version for the Italian market. In 2000, differences in priorities between the two firms had brought about an end to the partnership, with each developing the aircraft independently; Yakovlev received US$77 million for technical documents of the aircraft.
