The Qased (also Ghased, Persian: قاصد‎, lit. 'messenger') rocket is an Iranian expendable small-lift orbital space launch vehicle. It made its maiden flight in 2020, lofting Iran's first military satellite named Noor (Persian: نور‎, lit. 'light') into orbit.

Design

Qased is a three stage rocket. Its first stage is propelled by a Ghadr medium range ballistic missile with a diameter of 1.25 meters (4 ft 1 in), burning UDMH and N₂O₄ for 103 seconds and an approximate thrust of 30,000 kilograms-force (290 kN; 66,000 lbf), although Qased's application of the proven Ghadr as its first stage is limited to the first launches and subsequent launches are to utilize a solid fueled first stage. The 1 meter (3 ft 3 in) diameter second stage is the solid fueled Salman with a lightweight carbon fiber composite casing, a flexible nozzle with thrust vectoring capability, and a burn time of 60 seconds. The third stage was erroneously believed to be a Saman-1 upper stage with an Arash-24 solid fuel motor with a burn time of 40 seconds. Later publicly revealed images revealed it was a specific system developed by the IRGC.

Strategic implications

The launcher is notable as it is operated by the Islamic Revolutionary Guard Corps - Air Force rather than the Iranian Space Agency (ISA) and is small enough to be launched from a transporter erector launcher. The launch unveiled a full-blown parallel military space program separate from the ISA, with separate development paths and solid fueled launch vehicles, as opposed to the ISA's liquid fueled rockets.

In terms of the Noor satellite itself, the launch does not fundamentally change the security equations in the Middle East; however, the unveiling of the IRGC space program and its emphasis towards solid fueled launch vehicles (which are more military viable than Iran's previous liquid fueled launchers like the Simorgh) might indicate Iran's hedging strategy to acquire ICBM technology without the security repercussions of openly attempting to do so.
