HESA Simourgh, sometimes known as Simorgh (Persian: هسا سیمرغ) is an Iranian light transport aircraft unveiled on 19 May 2022. It is a variation of the IrAn-140 turboprop airliner, which evolved from the An-140. It is a general-purpose cargo plane and can carry troops or goods.

For commercial operations, the Simourgh is undergoing testing, and is expected to enter full operational service in 2027.

Development

According to Iranian official sources, the airplane is a modified version of the IrAn-140, which addresses some deficiencies of that design. According to pictures of the prototype Simourgh, there have been some changes to the wings, tail and fuselage compared to the IrAn-140 (the most notable difference being the cargo ramp added to the back of the aircraft).

The first prototype of this aircraft was first unveiled on 19 May 2022 by Iranian official news. According to military officials the plane was in the fast-taxi testing phase.

On 29 April 2023, a picture was published that showed the prototype version doing the fast-taxi test on the runway. On 30 May 2023, Iranian Ministry Of Defense reported that the aircraft has successfully had its first flight.

In December 2024, the Simorgh aircraft participated in various flights at the Kish Airshow in the Persian Gulf, featuring a new paint scheme.

On 29 October 2025, the Simourgh has completed 100 hours of flight time to get airworthiness certification from the Civil Aviation Organization (CAO).
