Sukhol Su-27
This supersonic fighter aircraft was originally from the USSR, built as a counteraction to a similar US plane. After making its first flight in 1977, it became an official servant of the Soviet Union in 1985. This ridiculously fast plane can reach speeds up to 1,500 MPH, which is more than double the speed of sound.
This particular model got the acclaim of being one of the best of its era, and even 30 years later there are still some models in Russia and the Ukraine.
