HESA Yasin

The HESA Yasin (Persian: یاسین) is an Iranian training jet unveiled on 17 October 2019. It is primarily designed for training fighter pilots, though it may also be used for close air support missions.

Developed by specialists within the Iranian Armed Forces, the Yasin is intended to enhance the training capabilities of Iran's air forces.

History

The Yasin Trainer Jet is an Iranian-developed aircraft designed for military training purposes. On 1 December 2023, the final prototype of the Yasin successfully completed its first flight, marking a significant milestone in its development and the Iranian aerospace industry.

The initial version of the Yasin Trainer Jet was unveiled in 2019. On 20 March 2023, the new and production-standard prototype of the Yasin was unveiled, and its production line was officially launched. On 9 September 2023, the aircraft successfully completed its taxi test.

Design

The weight of Yasin is 5.5 tons and can fly up to 1200 kilometers. The wing's design enables the jet to land and take-off at a speed of at least 200 km/h. The length of this aircraft is 12 meters and its height is 4 meters. Arming Yasin trainer jets for Close Air Support is being considered.

Crash Incident

One of the two pre-production prototypes of the Yasin, which was scheduled to be displayed at the Kish Air Show in December 2024, crashed during a test flight on December 5, 2024. The crash occurred due to navigational issues and a collision with the Firouzabad Mountains. The two pilots on board, Colonel Hamidreza Ranjbar and Colonel Manouchehr Pirzadeh, died in the accident.
