THE WASHINGTON INSTITUTE FOR NEAR EAST POLICY n AUGUST 2020 n PN84 PHOTO CREDIT: REUTERS © 2020 THE WASHINGTON INSTITUTE FOR NEAR EAST POLICY. ALL RIGHTS RESERVED. FARZIN NADIMI n April 22, 2020, Iran’s Islamic Revolutionary Guard Corps Aerospace Force (IRGC-ASF) Olaunched its first-ever satellite, the Nour-1, into orbit. The launch, conducted from a desert platform near Shahrud, about 210 miles northeast of Tehran, employed Iran’s new Qased (“messenger”) space- launch vehicle (SLV). In broad terms, the launch showed the risks of lifting arms restrictions on Iran, a pursuit in which the Islamic Republic enjoys support from potential arms-trade partners Russia and China. Practically, lifting the embargo could facilitate Iran’s unhindered access to dual-use materials and other components used to produce small satellites with military or even terrorist applications. Beyond this, the IRGC’s emerging military space program proves its ambition to field larger solid-propellant missiles. Britain, France, and Germany—the EU-3 signatories of the Joint Comprehensive Plan of Action, as the 2015 Iran nuclear deal is known—support upholding the arms embargo until 2023. The United States, which has withdrawn from the deal, started a process on August 20, 2020, that could lead to a snapback of all UN sanctions enacted since 2006.1 The IRGC’s Qased space-launch vehicle, shown at the Shahrud site The Qased-1, for its part, succeeded over its three in April. stages in placing the very small Nour-1 satellite in a near circular low earth orbit (LEO) of about 425 km. The first stage involved an off-the-shelf Shahab-3/ Ghadr liquid-fuel missile, although without the warhead section, produced by the Iranian Ministry of Defense.2 According to ASF commander Gen. -
The Iranian Missile Challenge
The Iranian Missile Challenge By Anthony H. Cordesman Working Draft: June 4, 2019 Please provide comments to [email protected] SHAIGAN/AFP/Getty Images The Iranian Missile Challenge Anthony H. Cordesman There is no doubt that Iran and North Korea present serious security challenges to the U.S. and its strategic partners, and that their missile forces already present a major threat within their respective regions. It is, however, important to put this challenge in context. Both nations have reason to see the U.S. and America's strategic partners as threats, and reasons that go far beyond any strategic ambitions. Iran is only half this story, but its missile developments show all too clearly why both countries lack the ability to modernize their air forces, which has made them extremely dependent on missiles for both deterrence and war fighting. They also show that the missile threat goes far beyond the delivery of nuclear weapons, and is already becoming far more lethal and effective at a regional level. This analysis examines Iran's view of the threat, the problems in military modernization that have led to its focus on missile forces, the limits to its air capabilities, the developments in its missile forces, and the war fighting capabilities provided by its current missile forces, its ability to develop conventionally armed precision-strike forces, and its options for deploying nuclear-armed missiles.

Iran's Space Program: Timeline and Technology
Report Iran’s Space Program: Timeline and Technology 29 Apr. 2020 Contents I- Iran’s Space and Satellite Program’s Timeline ..................... 1 II- Satellite and SLV Technology in Iran ................................. 3 Conclusion ...........................................................................6 Iran successfully launched its first dual purpose military-non-military Noor satellite into orbit on April 22, 2020. Produced domestically, the satellite was launched by a new Space Launch Vehicle (SLV), the Qased. The launch publicly disclosed military aspects of Iran’s space program that were previously denied. Noor has increased international concerns over Iran’s hidden Inter- Continental Ballistic Missile Program (ICBM). Iran’s latest satellite technological and military advancement is a far cry from its early commitment to United Nations treaties and principles promoting the peaceful use of space. Iran is a founding member of the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) launched in December 1958. The following sections review the timeline and technology of Iran’s space program, to show that it had a military component that evolved over time. I- Iran’s Space and Satellite Program’s Timeline Set up over a decade ago, Iran’s satellite and inter-continental missile technology was launched by the Islamic Revolutionary Guard Corps (IRGC)-affiliated Self-Sufficiency Jihad Organization (SSJO). The components of the program were laid out as early as 2004, when Iran established a Supreme Space Council chaired by its sitting president, and monitored by the Iranian Ministry of Communication and Informational Technology.1 In the early stages of Iran’s space program, communication satellites were developed jointly at lower cost with foreign space agencies. -

According to the Iranian Revolutionary Guards Corps (IRGC), the launch vehicle named ‘Qased’, which is Iran’s first three-stage satellite launcher, placed the satellite in orbit at an altitude of 425 kilometres. Iran’s space agency was established in 2004, and Iran emerged as a space faring nation in 2008 when it sent a rocket to space. Since then, the Iranian space programme has had a mixed record, with some launches attaining suborbital heights and even carrying live monkeys, while others failed. The most recent partial success occurred on 9 February 2020 when the communication satellite ‘Zafar 1’ was launched but could not be placed within the expected orbital parameters. While Iran has denied the allegation that its space programme is a cover for developing ballistic missiles, there are only minor differences between rockets lifting satellites into orbit and ballistic missiles tracing a parabolic arc through space to targets on ground. -
