In this June 30 speech, UK Ambassador Jonathan Allen provided some details on Iran’s Qased SLV:
We are deeply concerned by Iran’s development of advanced technologies under the guise of Space Launch Vehicle research and the roles these technologies play in supporting Iran’s military ballistic missile program. We reject Iran’s claims that the Qased system used in their most recent launch is not a military launch system. In addition to the self-proclaimed role of the Iranian Revolutionary Guard Corps in the launch, Iran’s official reports show a Transporter Erector Launcher, characteristic of military ballistic missiles and not a static launch done, or “gantry”, of the type normally associated with civilian Space Launch Vehicles.
The UNSG report to which he referred in his speech has more detail :
Iran stated that, unlike all of its previous space launch vehicle tests, this programme was developed and conducted by the Islamic Revolutionary Guard Corps. The Islamic Revolutionary Guard Corps is a military entity known to control Iran’s strategic missile forces. The launch was conducted from an Islamic Revolutionary Guard Corps facility in Shahrud which was not previously associated with such launches.
The design of the Qased second stage is based on a new solid-propellant motor and incorporates a new attitude control module. This solid-propellant motor design is similar to the Salman system unveiled by the Islamic Revolutionary Guard Corps in February 2020 along with a range of other new ballistic missile technology, including the Raad-500 short-range ballistic missile. The Salman featured a flexible-nozzle control system, rather than jet vanes used on other Iranian solid-propellant motors. This technology improves the motor’s efficiency and is essential for the development of larger-diameter solid-propellant motors suitable, primarily, in the design of long- range ballistic missiles. Official Iranian media reporting in February 2020 showed a static test of the Salman motor at the Islamic Revolutionary Guard Corps Shahrud facility. The test facilities at the Shahrud site include four additional static motor test platforms, which are only suitable for testing such larger-diameter solid-propellant ballistic missile motors.
Iranian state media reporting shows the Qased uses an attitude control module to control its orientation and flight path prior to satellite release. This technology has been derived from Iran’s development of ballistic missiles with manoeuvrable re-entry vehicles, such as the Emad variant of the Shahab-3 and the Qiam-2.
The attitude control system on the Qased demonstrated the capability to accurately control and orient a vehicle outside the atmosphere. This is an essential technology for the development of a long-range ballistic missile system capable of deploying both multiple re-entry vehicles and multiple independently targetable re-entry vehicles.
