Iran has uncovered plans to develop satellite launch vehicles that could send up to 15 tons of cargo into orbit, the Iranian Defense Ministry said on Tuesday. 

Ahmad Hosseini Mounes, Iran's space division spokesperson, said the country's innovative space pursuits are “completely scientific and technological” and do not rely on any foreign entity's permission. 

Hosseini Mounes also discussed plans for the satellite vehicles in more detail, saying that the Sarir satellite launch vehicle will be sent to orbit carrying 15 tons of cargo. 

The Sarir launch vehicle can either launch multiple (six or seven) satellites at low altitude levels or one satellite that can travel up to 36,000 kilometers above Earth's surface.

For the future, Hosseini Mounes said Iran is developing the Soroush satellite launch vehicles, which would be able to carry six to 15 tons of cargo.
