I believe that is an Su35/37, a follow-up to the Su27 (hard to tell but it looks like the 35). The Russians have gone well past the days of copying American/British aircraft and moved ahead of the west.
The Russians copied a “captured” B-29 at the end of WWII right down to the rivets. They even copied the patches used to repair bullet holes! The venerable Mig-15, scourge of Korea used engines thet were exact copies of Rolls Royce engines, the finest of the day. Now it seems we may want to do some “copying” of our own!
They didnt steal those Rolls engines for the Mig-15 either, they were engines for the Glouster Meteor, and were actaully sent to Russia with the blessing of the then-British government as a good-will gesture to fullfill a wartime promise to share that technology. The Ruskies back engineered them, made a few improvements then built the jet around it, but the Mig’s centrifical-flow jet engine was already being surpased in the US with the axial-flow engine, this engine was the cheif advantage the F86 had when it went head to head with the Migs in Korea in “Mig Alley”
Some of the Russian versions of western planes are downright frightening…the XB-70 copy in particular, but the Boing 727, the Concord, the B1, the Space Shuttle! all have Ruskie “me-too” copies, plus a lot others.
Heads up, check your local PBS station to when they will repeat on the show Nova, "Missing in Mig Alley, in which they discuss the differences of the Mig and the F86 and the Korean war.
