"The Iran Aviation Industries Organisation Kowsar-88 Yasin was officially revealed to public. The aircraft made its first flight, most probably on 15 October 2019.
The Yasin was already shown in April 2017 and its first flight was initially planned for mid-2018. A scheduled five year test-programma is reported, with service entry around 2023. The aircraft is powered by two J90s, better known as the General Electric J85. This type of engine is also used in, for instance, the F-5 family of fighters.
The Yasin is expected to be purchased by the Islamic Republic of Iran Air Force (IRIAF) as its advanced jet trainer and light attack aircraft. In 2017, the IRIAF said it wanted fifty aircraft. If ordered, the aircraft will replace the fleet of F-5B's. But, as many projects within Iran, it is uncertain if this will actually happen."
