State TV broadcast footage of the aircraft performing during the parade on Thursday. The planes include the latest all-Iranian fighter jet, dubbed Kowsar, which in Islamic meaning refers to a river in paradise and is also the title of a chapter in the Muslim holy book, the Qur’an. The twin-seated Kowsar — modelled after American F-5 fighter jet — was inaugurated in 2017, when the TV aired images of President Hassan Rouhani briefly sitting in the plane’s cockpit inside a hangar before the ceremony. The parade also showcased the Saegheh, or “Thunderbolt,” another domestically built fighter plane. Iran’s air force already has US-made and Russian-made Sukhoi aircraft in service.
