Yasin / Kowsar 88 advanced jet trainer
The HESA Kowsar (Persian: thunderbolt), also known as Kosar, is an Iranian jet aircraft equipped with new fourth generation avionics in combination with an advanced fire control system. The aircraft was designed by experts of Iran Aviation Industries and Islamic Republic of Iran Air Force as advanced training jet.
The Yasin All-Iranian Advanced Training Jet is 12 meters long, 4 meters high and and weighs 4.3 tons load-free under operational take-off conditions [other reports claim it weighs five and a half tons without further specification]. It can fly up to 12 km altitude. The wing is designed to be more than 4 meters long and 2 meters wide so that it can land at a speed of the best training aircraft in the world and take off at sea level quickly. The presence of a fully rotating tail fin eliminates the pilot's restriction on various maneuvers, especially spin-off or rotational crash. The Yasin Advanced Training Jet utilizes a 7,000-pound thrust turbo jet engine. The aircraft's ejection seat is capable of working at zero speed and under any circumstances, propelling the pilots out of the fighter jet in a fraction of a second to a height of up to 100 meters.
Iranian Defense Minister Brigadier General Ahmad Vahidi announced on 20 April 2013 that the country planned to display new home-made defensive products in the near future, including a new aircraft for training purposes, and an air-launched cruise missile. "We have on the agenda the production of other types of fighter jets and we will unveil Kowsar training jets in a not too far future," Vahidi told reporters on the sidelines of the military parades held in Tehran on the occasion of the National Army Day.
The first Kowsar 88 (also named Kosar) prototype jet trainer was unveiled 15 April 2017. This jet will form future fleet of IRIAF Iranian Air Force advanced jet trainer airplanes until 2025. The Kowsar trainer strongly resembles the AIDC AT-3 Tzu Chung aircraft developed by the Aerospace Industrial Development Corporation of the Taiwan in collaboration with American aircraft manufacturer Northrop between 1984 and 1990. It also resembles the CASA C.101 Aviojet Trainer and Light Attack Aircraft, and the Yak-130 Russian air force's advanced flight and tactical combat trainer -. But close examination confirms that it is a copy of none of these.
Managing-Director of the Iranian Aviation Industries Organization (IAIO) Manouchehr Manteqi announced the country's plans to test a new home-made training jet named 'Kowsar 88' next year. "Kowsar 88 jet will go under tests in the next Iranian year (which starts on March 21, 2015) if the plans go ahead with no problem," Manteqi said 04 December 2014.
Iran was in final stages of manufacturing its new home-made training jet, ‘Kowsar’, Air Force Deputy Chief Liaison Officer General Aziz Nasirzadeh said February 9, 2015, adding that the country is also ready to start exports of flight simulators to foreign nations. “The double-cockpit Kowsar jet which is being designed and built in cooperation with the defense ministry’s aerospace industries organization is in final stages of manufacturing,” Nasirzadeh said.
He also elaborated on the country’s capabilities in building simulators for different types of aircraft, and said, “The Air Force has designed and built simulator systems for all airplanes using the most state-of-the-art technologies and we have reached full self-sufficiency in this regard.” He also underlined Iran’s preparedness to export different types of simulators to other countries.
In relevant remarks in December 2014, Managing-Director of the Iranian Aviation Industries Organization (IAIO) Manouchehr Manteqi announced the country’s plans to test ‘Kowsar’ training jet next year. “Kowsar 88 jet will go under tests in the next Iranian year (which starts on March 21, 2015) if the plans go ahead with no problem,” Manteqi told FNA.
On 15 April 2017 President Rouhani visited Iran Helicopter Support and Renewal Company (IHSRC) and ordered the unveiling of a jet trainer named Kowsar, Mohaajer 6 tactical drone, Nasseer anti-ship cruise missile, and Fakour air-to-air missile. During the ceremony, the IAIO Qaher-313 fighter also started taxiing test and preparation for take-off at President Rouhani's order. The ceremony continued with delivering 20 helicopters, which were undergone major overhaul, to the armed forces. At the beginning of the ceremony, Dr Rouhani reviewed the honour guards and paid tribute to the martyrs of the Sacred Defence era, as well as those of the Ministry of Defence. The President also visited different parts of the exhibition on the achievements of the defence ministry and was briefed about the latest developments and advancements in Iran's defensive capabilities.
The all Iranian Yassin Jet Advanced Trainer was unveiled 16 October 2019 in the presence of Brigadier General ' Ali Hatami " Minister of Defense , Brigadier General pilot 's Nasirzadeh commander of the Air Force and Surena Stari Science and Technology Vice President , in Nojeh martyr base in Hamadan. The training aircraft made its first official flight over the martyred base of Nujah after completing the final test stages on the orders of the Army Air Force Commande.
The Iranian Air Force is considering the use of the Yasin jet trainer in the light attack role. In an interview with Iranian state TV on 26 October 2019, Amir Karim Bani Tarafi, the Chairman of the Iran Aviation Industry Organization, said the Air Force is examining the prospect of using Yasin for close air support missions (CAS). He said, “At present, the plane only has a training function, but it can be in the future completed and equipped with bombs and missiles and be used as a CAS plane.”
Bani Tarafi underlined that one of the problems facing Iran in manufacturing the training jet was its engine, but the problem was eventually overcome and the engine was later mass-produced by Iranian experts and used in Yasin. Yasin utilizes two 7,000-pound-thrust turbo jet engines, which is used for jet fighters.
Iran unveiled and put into operation the domestically-manufactured training jet, which is "among the world’s best" in terms of takeoff and landing capabilities. The advanced jet, dubbed Yasin, was put on display in the presence of Defense Minister Brigadier General Amir Hatami, Commander of the Islamic Republic of Iran Air Force (IRIAF) Brigadier General Aziz Nasirzadeh and Vice President for Science and Technology Sorena Sattari.
He added that the Air Force is assessing its requirements, suggesting that the Air Force would typically require between three and four squadrons with 16 jets each, or a total of 48 to 64 aircraft.
