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).^[1]^[2]^[3]

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.^[1]

On 29 April 2023, a picture was published that showed the prototype version doing the fast-taxi test on the runway.^[4]

On 30 May 2023, Iranian Ministry Of Defense reported that the aircraft has successfully had its first flight.^[5]

Difference with IrAn-140

Despite IrAn-140 which has trapezius-shaped wings, this aircraft has rectangular wings to give it more lift. Also the horizontal stabilisers went from V-shaped to completely horizontal. the back part of fuselage has also been modified. But the most notable difference is the cargo ramp added to HESA Simourgh.^[1]^[3]^[2]
