Did you know that the Soviet era Su-27 was built on US F-15 Technology – While comparing Western to Eastern technology and fighter jets we cannot skip over two widely compared aircraft: Sukhoi Su-27 Flanker and the McDonnell Douglas F-15 “Eagle” (now Boeing F-15 Eagle). In the eastern aviation, Sukhoi stands for a legend. The Sukhoi design bureau made such successful aircraft as the Su-24 Fencer strike fighter and the Su-27 Flanker series of air superiority fighters. The Sukhoi Su-27 Flanker was the top of Soviet technology at the time of its debut in the mid-80’s. Large but exceptionally agile, it had powerful engines and a big load of weaponry. With the Flanker fighter jet, the Soviet aviation industry made a leap forward in military technology. The Su-27 is a really great aircraft and a huge success of Soviet aviation.
Few know it, one of the most mass-produced Soviet/Russian fighters, the Su-27, was based partly on American technology, which enabled it to set over 30 world records.
The Sukhoi Su-27 Flanker is a multi-purpose fighter-interceptor that can carry out combat missions day and night in all weather conditions. The Su-27’s capabilities are formidable. It is capable of flying at more than twice the speed of sound , the Flanker can reach Mach 2.35 , has a service ceiling higher than 18,000 metres,and has a flight range of more than 3,000 km.
Like most weapons of Soviet origin, the aircraft’s task was to counterbalance or even outperform American firepower. In this case, the F-15 Eagle.
In the early 1980s, soviet intelligence agents somehow got hold of the blueprints of the F-15 Eagle, designed by McDonnell Douglas, and handed them over to the Sukhoi Design Bureau. Soviet engineers used them to create the first prototype of the new fighter. The intelligence data was incomplete, so the “hijacked F-15 model” lacked the supersonic speed and aerodynamic performance than the real F-15.
In the end, it was decided to combine the model with 1970s Soviet technology, and in 1981 the first T-10S took to the skies, which later became known as the Su-27.
All subsequent models designed by the Sukhoi Design Bureau (Su-30, Su-34, Su-35, Su-57, etc.) were based on the Su-27.
