Simorgh (Safir-2) is the second iranian space launcher. It might be related to the alleged Shahab-5 IRBM and the North Korean Unha launch vehicle.
Simorgh is two stage vehicle with a first stage of 2.5 m diameter with four engines of Safir-1 heritage. The main engines are fixed, while steering is provided by four small vernier engines. Possibly the first stage shares technology with the alleged Simorgh-5 ballistic missile and is likely based on the North Korean Unha rocket.
A liquid fueled second stage with four engines is probably based on an enlarged version of the Safir-1 second stage. Possibly also a small solid fuel third stage might be carried.
The 25 m high rocket has a capability to put 350 kg into a low earth orbit. It weights about 87 t on lift off.
The first flight took place in March 2016 on a suborbital trajectory. The first orbital attempt was launched in July 2017, but failed.
