HESA Simourgh (Persian: هسا سیمرغ) is an Iranian light transport aircraft unveiled on 19 May 2022.

The aircraft is a modified version of the Iranian IrAn-140 turboprop airliner (itself based on An-140) and is suitable for transporting goods or even troops.

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).
