The ceremony was participated by the Iranian Defense Minister Brigadier General Amir Hatami, Iranian Army Commander Major General Abdolrahim Mousavi, Commander of the Islamic Republic of Iran Air Force (IRIAF) Brigadier General Aziz Nasirzadeh, and Head of the Management and Planning Organization (MPO) Mohammad Baqer Nobakht.
Iran last September unveiled Kowsar which is equipped with avionics (aviation electronics) and fire-control systems.
Kowsar was unveiled in a ceremony participated by Iranian President Hassan Rouhani in Tehran who ordered the fighter jet to fly.
The new fighter jet uses the fourth generation of military digital network and is equipped with heads-up display (HUD) system to increase the precision-striking power of weapons, advanced and multi-purpose radar for fire-control to boost the precision to trace the targets and threats and high-precision navigation system.
Kowsar can be manufactured in two types of single-cockpits and double-cockpits and the second type can be used for training pilots in addition to enjoying combat capabilities.
According to the Iranian officials, the fighter jet is a supersonic combat plane different from the training Kosar 88 plane unveiled in April 2017.
Meantime, Army Lieutenant Commander Brigadier General Mohammad Hossein Dadras announced last September that Kowsar had gone on line for mass-production.
"The defense ministry, in cooperation with the Air Force, is mass-producing the fighter jet," General Dadras said.
He added that Kowsar had undergone different ground and air operational tests by the Iranian Air Force experts for numerous hours.
"We have ordered this fighter jet for the Army," General Dadras said.
