Russia’s official designation of the PAK-FA/T-50 jet as the Sukhoi Su-57 is just another reminder that the field of fifth generation fighters is about to get more crowded. The United States, China, Russia, Japan and Korea are all working on their own fifth generation designs, but so far only three planes, the F-22 Raptor, F-35 Joint Strike Fighter and the Chinese J-20 are operational. Increased tensions between the United States and NATO on one side and Russia on the other have people wondering: once the Su-57 does become operational, how will it stack up against the F-22 Raptor
