Iran (IP): Kowsar training fighter aircraft is the result of a collective effort of Iranian aviation industry experts in order to acquire the knowledge of supersonic training and combat jets.

Iran PressIran News: This fighter has completed all its implementation stages in the Iran Aircraft Manufacturing Industrial Company (HESA) owned by the Ministry of Defense and with the participation of the Air Force of the Islamic Republic of Iran's Army.

Kowsar Training Fighter is a third-generation fighter with avionics (flight electronics) of the fourth generation, which has been completely indigenized to carry out close air support missions and advanced training in Iran, modeled on the F-5F training fighter, which has made Iran among few countries with the technology to design and build fighter aircraft with 4th generation avionics and fire control systems.

The propulsion system, avionics equipment, central computer, monitors, multifunction radar are among the advanced and updated equipment in this fighter aircraft.

Kowsar fighter is made in two types of single-piolet and two-piolet, which the two-cockpit type, in addition to combat capability, is used for training pilots in the advanced stage.

This fighter uses a domestically-made Iranian turbojet engine called Owj(Pinnacle).


The Owj engine is the first jet engine made in Iran, which is based on the G85 turbojet engine used in F-5 aircraft and has the ability to fly up to 50,000 feet and can be installed on a variety of aircraft with a take-off weight of up to 10 tons.

The fighter also uses advanced 4th generation avionics and fire control systems such as color and multi-purpose monitors and a head-up display (HUD) system.


The use of radar warning systems ( RWR ), Identification, friend or foe system ( IFF ), weapon management and weapons processor, chaff/flare launchers, new generation radio for secured communication have also been considered which natively designed and developed.

The native "Sarir"(throne) ejection seat s installed in this aircraft, which has the ability of zero-zero ejection. The indignation rate in this aircraft is 88%.


There will be no problem in the field of Kowsar fighter maintenance due to the familiarity of experts, and in addition to saving currency in the design and construction of Kowsar fighter, the process of using it in operational units is less expensive and as a suitable platform, it will be considered for training or combat flight of pilots with new generation aircraft because it is equipped with up-to-date systems according to the existing needs of Army Air Force.

The unveiling of this aircraft took place on August 21, 2018, and on June 25, 2020, during an official ceremony, three Kowsar fighters were delivered to the Air Force of the Islamic Republic of Iran.
