The new jets are just one of a group of military improvements that include new tanks and an electro-optical surveillance system that functions as a backup for radar, the Fars News Agency reported.
Brig. Gen. Ahmad Mighani told Press TV the new fighter jets would be able to prevent any violation of Iranian air space.
"We have upgraded our air force fleet, radar systems and missile systems over the past few years, and we are now ready to counter any threat," Mighani said.
Iran has threatened to counter-attack if Israel launches an air strike aimed at its nuclear facilities.
