Raad / Taer / 3rd Khordad

The "3rd Khordad" (Khordad is the third month of the Iranian calendared) air defense system is a notional Iranian stand-in for the S-300 system Russia stalled on providing the Islamic Republic. The 3rd Khordad system, developed and manufactured by the Islamic Revolutionary Guard Corps (IRGC)'s military industries, was seemingly a copy of the Russian S-300, created to mimic the Russian S-300.

Raad ("Thunder") is an Iranian tactical short-range anti-aircraft missile system, whose development was carried out by the Iranian Revolutionary Guard. Externally it resembles the Soviet or Russian SA-6 Buk and Buk M2 systems. While 2012 when the Raad system was unveiled, the range was claimed to be 50km and the Sayyad-2 was claimed to have the same range. All those ranges seem to be too high as the similar 2010 vintage Buk-M2 and HQ-16 have ranges of 40-45km.

The air defense system was first presented to the public in September 2012 in a military parade. Because of the arms embargo against the Islamic Republic of Iran's Iranian air defense systems have been increasingly developed since the 1990s, on the one hand to replace outdated technology and to demonstrate that the investments of the Iranian nuclear program can be effectively protected against air attack. Accordingly, as in other forces, a multi-layered defense strategy consisting of short-, medium- and long-haul systems was pushed. The middle-range system Raad should be together with the Bavar-373Air defense system covering the medium and long range. According to the news agency Fars , it is designed to combat fighter aircraft, helicopters and drones, specially made in the US. The first tests were carried out during the maneuver Velayat 91 in December 2012.

The technical data of the individual Raad versions are based on official Iranian publications. The extent to which the information can be accurate is difficult to verify.

  • Taer : The missiles are designated Taer, an Arabic word meaning omen, or bird, the ambiguity stemming from the fact that many ancient peoples took their omens from the movements of birds. Taer-2, it should be mentioned, although the overall length and body diameter in the propeller area of the missile are apparently close or similar to the Taer-A model, it has been shown since 2012, but contrary to this example, Taer-2 has a fixed diameter from the end to the nose of the rocket. While 2012 when the Raad system was unveiled, the range was claimed to be 50km and the Sayyad-2 was claimed to have the same range. All those ranges seem to be too high as the similar 2010 vintage Buk-M2 and HQ-16 have ranges of 40-45km.
  • Raad : The three-axle launch vehicle carries three Taer missiles that can track and hit targets at distances of up to 50 km and at altitudes of 20 km.
  • Alamolhoda : At the starting vehicle is a camera optics, with which the target is tracked. Iranian agencies indicate effective control ranges of 80 km.
  • 3rd Khordad (named after the third month of the Iranian calendar ): TELAR with a phased array radar and Taer 2B missiles. Iranian al-Quds units are said to have brought the 3rd Khordad system to Syria , where it is said to have been destroyed in April 2018 during an Israeli air strike. The "Khordad 3" anti-air missile system was unveiled in 2014 during an inspection visit by the Revolutionary Commander of the Revolutionary Guards' Armored Forces exhibition and revealed the system's ability to target hostile aircraft from a distance of 50 kilometers.
  • Tabas : Similar in configuration to the 3rd Khordad version, however, it is equipped with another radar, the Soviet 9S35 radar radio measuring system. This version uses Taer 2A missiles.

The Alam-Al-Hoodi Air Defense System utilizes a long-range radar in the VHF band (the ability of this frequency spectrum to detect radar cross-sectional targets is very low), as well as parts of the Thunderbolt air defense systems.

Fire control radars for accurately determining the position of the target in the sky require high resolution and high resolution. Hence, due to the inherent error of several hundred to several hundred meters, the VHF / HF band radar detects positions in air defense sets of these radars only for The initial identification was used and the fire control task was delivered to radar in bands such as x. On the other hand, the range of these radars falls sharply against aircraft with low radar cross-sections.

Previously, activities have been seen to use VHF radars for initial detection and transfer of data with lower frequency radars or other types of sensors to control fire and provide practical solutions to counteract the world's most secret targets. But according to information published at the IRGC Aerospace Force, the radar of Alam-al-Hoda (the main radar of the Al-Hoda Air Defense System) is engaged in the discovery, tracing, and directing of fire against targets, which, in view of the inherent problems of the frequency band, Determining the exact location of the goals is unprecedented. Therefore, Irans experts must find a way to overcome this problem.

The radar consists of two main horizontal and vertical sections, which, with its large length of transport, can be folded onto a two-axle trailer, and its displacement capabilities are faster and faster. It should be noted that in general, fuzzy arrays have the ability to quickly scan the environment, have high stability against electronic warfare, and are able to detect and track a large number of targets.

Obviously, as the next target of the Thunderbolt air defense systems is reaching the level of capabilities of systems such as the S-300, other components of this defense suite should also be developed within Iran. Therefore, it can be concluded that the Radar of Al-Hadi as an Iranian example is one of the important species of the Nebo radar, a radar explored as similar to the radars of Bashir and Ghadir and Aliam, each one with the ingenuity and ingenuity of young engineers. Specialists of the Iranian lines have found differences with similar or similar foreign samples forming a modern and integrated set of national air defense.

While the provision of airborne radars and air defense complexes that are in full compliance with indigenous needs is today much more difficult than before, the internal construction of these radars and missiles required not only to meet the basic needs of defense. But on the way to cover more and more of all the necessary areas and, in the long run, will replace the existing systems with modern and native products.

About the missile on the launch vehicle of the Al-Haday system, which is of type Taer-2, it should be mentioned that although the overall length and body diameter in the propeller area of the missile are apparently close or similar to the Taer-A model, it has been shown since 1991, but the Contrary to this example, Taer-2 has a fixed diameter from the end to the nose of the rocket.

As a result, the internal volume of the rocket will be more than the previous generation. Considering that this increase in mid-to-nose sections is likely to be less than that, the missile propellant will be much more involved, and more of this space will be added to the new guidance and control systems.

According to the specifications announced on June 3rd, the user of the Taer 2B missile, the new missile has a range of 50 kilometers and its flight ceiling is 25 kilometers. Reaching this altitude to destroy all types of current combat aircraft and even examples that are being added in the near future to the enemy combat organization is quite enough to engage in tactical long-range rockets.

It should be considered that processing fast and synchronous radar data based on the signals received from the targets, determining more dangerous targets, assigning missiles to targets and directing the missiles are activities that even if the missiles are available The active radar by the system should be implemented and new Iranian systems can simultaneously implement all these activities for four targets and eight missiles.
