Safir-2


Iran's first orbital launch vehicle, based on the Shahab 3 intermediate range ballistic missile with upper stages.

high resolution Yantar-4K. The project was to be implemented in two phases: the Yantar-4K1, launched by the existing Soyuz-U launch vehicle.

In November 2004 US intelligence sources stated that the version of the missile used in 2004 tests had been stretched 15% and equipped with a larger payload fairing, indicating possible preparations for the long-announced Iranian indigenous satellite launch. A stretched Shahab-3 with improved performance, topped with two upper stages, would be equivalent to the French Diamant launcher of the 1960's. It would certainly be capable of orbiting the 60 kg Mesbah satellite mentioned in the press, and possibly the 170 kg mentioned for the follow-on satellite.

Photographs had circulated since 1998 of a Shahab-3 outfitted as the 'Iris' satellite launcher, complete with an improbably large payload fairing. This is unlikely unless the Iranians planned a leap to Lox/LH2 upper stage engine technology for the upper stage. This may not have been as improbably as it may sound. The Chinese achieved a similar feat with their CZ-3 upper stage in 1984, becoming the third nation to fly this technology.

The following are two possible reconstructions:

Storable liquid propellant first and second stages, solid propellant kick stage.
