The Sejil missile (Persian: سجیل, meaning "Baked Clay" (see Surat al-Fil of the Quran)), also known as Sejjil, is a family of Iranian solid-fueled ballistic missiles. The Sejil are replacements for the Shahab liquid-fueled ballistic missiles. According to US Pentagon sources, the missile profile of the Sejil closely matches those of the Ashura (Ghadr-110) and the Samen.[2]

Sejil-1[edit]

The Sejil is a two-stage, solid-propellant, surface-to-surface missile (SSM) produced by Iran with a reported 2,400 km (1,500 mi) range. A successful test launch took place on November 13, 2008.[3] Its range, if confirmed, would allow it to strike targets as far away as Israel and southeastern Europe, though Iran asserts that it is intended for purely defensive purposes.

Design[edit]

According to Jane's Information Group, details of the design other than the number of stages and that it uses solid fuel have not been released. Uzi Ruben, former director of Israel's Ballistic Missile Defense Organization, indicated that, "Unlike other Iranian missiles, the Sajil bears no resemblance to any North Korean, Russian, Chinese or Pakistani (missile technology). It demonstrates a significant leap in Iran's missile capabilities." Rubin went on to state that the Sejil-1 " ... places Iran in the realm of multiple-stage missiles, which means that they are on the way to having intercontinental ballistic missile (ICBM) capabilities ..."[4]

As a weapon, the Sejil-1 presents much more challenge to Iran's potential enemies, as solid-fuel missiles can be launched with much less notice than liquid-fueled missiles, making them more difficult to strike prior to launch.[5]

Sejil-2[edit]

Sejil-2 is an upgraded version of the Sejil.[1] The Sejil-2 two-stage solid-fuel missile has a 2,000 km range and was first test-fired on May 20, 2009.[6] The Sejil-2 surface-to-surface medium-range ballistic missile (MRBM) was first tested eight months prior to the actual test launch, which took place in the central Iranian province of Semnan.[7] Improvements include better navigation system, better targeting system, more payload, longer range, faster lift-off, longer storage time, quicker launch, and lower detection possibility.[8]

The new missile utilizes composite solid-propellant fuel and unlike the Shahab-3 medium-range ballistic missile (MRBM), which is launched only vertically, the Sejjil could be launched at a variable angle.[9]

On December 16, 2009,an upgraded version of Sejil-2 was test fired.[10] This new version of the Sejil-2 is faster during the powered flight portion of its trajectory and also during the re-entry phase. It is also harder to detect for anti-missile systems, as it is covered with anti-radar material. The new highly maneuverable missile is also more efficient as it requires less time for prelaunch preparations.[11]

Political commentator Kiyan Nader Mokhtari elaborated more about the features of the new missile. "The engine and various fuels have been tested and the platform is now highly reliable. The latest tests to be carried out are mainly to do with the variety of warheads that it has to carry," he said. "Some of the warheads obviously have been designed to be able to evade anti-ballistic missile defenses of the enemy in actual battle conditions," he added.[11]
