Is there any information on Sino-Russian dogfight contests? It would be quite exciting to watch the J-20 and T-50 go at it one day, but as friends with dud missiles. It would also present the PLAAF and RuAF with an unprecedented opportunity to do DACT between 5th generation air superiority aircraft, a privilege even the US lacks, since the F-22 vs the F-35 is not a fair fight.
