The Saman-1 is a space tug in development by the Iranian Space Research Center to be used to transfer satellites from a 400 km orbit to higher orbits. The system was unveiled on February 1, 2017, by Iranian president Hassan Rouhani in a ceremony marking the Iranian national space technology day.

Simorgh, also called Safir-2, is an Iranian expendable launch vehicle under development. It is the successor of the Safir, Iran's first space launch vehicle. Its mission is to carry heavier satellites into higher orbit than Safir.
