March 17, 2021: Iran revealed that it had tested a new SLV (Satellite Launch Vehicle) called Zuljanah in early February. The rocket was described as being able to put 220 kg (484 pounds) into a 500-kilometer-high orbit. The payload could be one satellite or up to ten “smallsats”. The 52 ton Zuljanah was a breakthrough for Iran because the first two stages used solid-fuel and only the third stage used more controllable liquid fuel propulsion to put the satellite in orbit or maneuver a nuclear warhead towards a target below. Iran denied that Zuljanah was really part of their continuing effort to develop an ICBM (Inter Continental Ballistic Missile) capable of delivering a nuclear warhead to the United States.
