Flight into fantasy. There have been feverish stories about Iran imminently getting the latest you-name-it tactical jet from X or Y for 20 years and it never materializes. Furthermore, you do not immediately get to press a complex and unknown new jet into service, it takes years. Then, the J-20 has never been exported, as it is the currently the prime longer range jet for the PLAAF allowing greater penetration of the eastern skies. Perhaps J-10s are an option if China can assuage the fears of the Gulf States with which it also entertains relations.
