Sukhoi T-50 PAK-FA
In the late 1980s, the Soviet Union outlined a need for a next-generation aircraft to replace its MiG-29 and Su-27 in frontline service. Two projects were proposed to meet this need, the Sukhoi Su-47 and the Mikoyan Project 1.44. In 2002, Sukhoi was chosen to lead the design for the new combat aircraft, and in the summer of 2009 the design was approved.[20] The PAK FA will incorporate technology from both the Su-47 and the MiG 1.44
