It looks like the F-35 Joint Strike Fighter officially has some fifth-generation fighter competition. South Korea is eying Sukhoi's PAK FA stealth fighter as an option for its next gen fighter fleet.
In addition to the PAK FA, Soul is looking at F-35, Boeing's F-15SE Silent Eagle and the Eurofighter Typhoon. Quite the interesting crowd for what will no doubt be an interesting competition to supply the ROKAF with 60 fifth-gen fighters. Keep in mind that the Sukhoi is just year into flight testing and the F-35 is still not out of the woods fiscally.
South Korea is set to declare a winner in October 2012
