In the United States compared to the su-57 and the Chinese J-20
Promising Russian fifth-generation fighter, the su-57 is distinguished by flexibility, while the advantages of aircraft Chinese Chengdu J-20 should also include stealth, the author believes The National Interest Dave Majumdar.
American magazine notes that the maneuverability of the su-57 is superior to the Chengdu J-20, even with the engine of the first stage of the AL-41F1, and in the case that the Russian fighter will get power unit “product 30”, its possibilities are nearly equal to those in the Lockheed Martin F-22 Raptor.
Meanwhile, the publication says, if the Chinese fighter will get a more advanced engine, research the Chengdu J-20 is closer to the su-57. On the other hand, the magazine notes, su-57 is inferior to the Chengdu J-20 in the implementation of stealth technology than the Chinese fighter resembles the American F-22 Raptor and Lockheed Martin F-35 Lightning II.
“The bottom line is that the Russians and Chinese had different requirements and design priorities, which forced them to go to the various trade-offs when developing their fifth generation fighter,” concludes Majumdar.
