Alder Surface to Air Missile

The topic of creating SAMs in Ukraine has been raised more than once. For the first time, the Ministry of Defense announced plans to create its own medium-range SAM in Ukraine in 2001. After a long pause, the Defense Ministry revived the discussion on the establishment of a domestic SAM in 2008. After that, both representatives of the Ministry of Defense and the heads of a number of defense enterprises and structures responsible for the export of Ukrainian weapons began to mention this. In 2010, it was claimed that the approximate financial need for the development and deployment of production for serial production of such SAM is 3-4 billion UAH in the prices of that period. But beyond words and good presentation booklets and movies, it didn't work out.

Since 2014, in the face of a constant military threat from Russia, the need to create new models of weapons in the air defense segment is an absolutely urgent task. After a detailed study of all structural, technological and technical nuances of this issue, the State Committee "Luch" submitted to the Ministry of Defense of Ukraine a proposal to create a new medium-range SAM with a stated maximum range of 100 km. Moreover, subject to much more modest requests for funding, compared with the previously mentioned 3-4 billion UAH. And provided very realistic deadlines to achieve the desired result. This is a SAM, which is based on a modified-to-air guided missile of the high-precision volley fire system "Alder", which has been adopted and is being mass-produced in the interests of the Armed Forces since 2019.

The refinement of the missile is aimed at the guaranteed destruction of typical air targets, including those that today can only counteract the S-300 SAM. Rocket launch - from TPK. Containers - regular from S-300 which are made today by the Vizar enterprise. The missile control circuit is close to that already worked out during the modernization of the S-125 SAM. The missile can be equipped with both semi-active and active homing radar head with an inertial guidance system and data line. This homing head was developed by Radionics and provides detection and capture of radar targets with EPR = 3 m at a range of about 20 km, which significantly increases the accuracy of missile guidance, including highly maneuverable targets.

The installation of an active GOS will significantly change the methods of aiming the missile at the target. Instead of radio command control, the method of combined guidance will be implemented. In the initial section of the flight path of the missile, inertial guidance with a constant angle of bias is used. This method is used in the "pitch" plane and provides after the launch of the rocket into the upper, more sparse layers of the atmosphere. The missile on the initial section moves on an aeroballistic trajectory. Such a missile flight significantly increases the long-range boundaries of the SAM zone for both low-speed and low-altitude targets.

The use of an active GOS missile at the end of the trajectory allows to implement the principle of "shot and forget", which significantly reduces the working time of the complex for finding and capturing targets for support. The use of a complex phase-manipulation sequence as the probing signal of the active GOS allows to significantly reduce the effect of active intentional interference on the missile homing head, which provides a high probability (more than 0.9) of hitting the target.

In addition to DerzhKKB "Luch" and the company "Radioniks", about ten other key domestic enterprises are involved in the cooperation for the production of such a medium-range SAM, including the Zhulyansky Machine-Building Plant "Vizar", which assembled 5B55 missiles for the S-300 during the Soviet era. Pavlograd Chemical Plant (creation and production of new mixed solid rocket fuels), developers and manufacturers of ground-based self-propelled platforms and automotive equipment.
