I’m sorry to say but in my opinon it (j-10) does not match up to F-15C. My reasoning for this is because the F-15 has many hardpoints and great agility but the J-10 has 11 harpoints. From first glance this is IMPRESIVE but look carefully and you will know that 4 harpoints are for dumb bombs. I also doubt its agility, it seems too fat to be as agile as its hyped up to seem. Modern fighters with agility aren’t very fat unless its the Falcrum SMT which IS not as agile as the orginal because of the fuel. In my opinon J-10 is probabily not as a Falcrum is a dog fight but I believe that its role is very CLOSE to the Mirage 2000! J-10 seems to be Mirage. As for its radar, it would be impresive expecially if it is a Su–27 radar but isn’t the nose of the Su-27 twice as big than the J-10 to accomadate the radar?
