Yenisei 77T6 ABM Engagement Radar

Yenisei 77T6 ABM Engagement RadarAt the end of April 2021, the Yenisei radar was adopted by the Russian army. The name "Yenisei" was already carried in the past by the SPOON REST mobile anti-jamming two-coordinate radar station of the meter wavelength range of the P-12 radar. This locator entered service with the radio engineering troops (RTV Air Defense Forces) in 1956 and for many decades served in the field of protecting the airspace of the USSR.

This radar is drawn with an enlarged rendering of the antenna head module of a 92N6E Grave Stone. The 10 x 10 BAZ-69096 chassis indicates the need to carry a much heavier radar than the 92N6E Grave Stone, which is consistent with the ABM radar function which requires greater power-aperture product performance compared to a SAM engagement radar. The size of the folded antenna is similar to that in the proposed wheeled 9S19MK Imbir / High Screen ABM acquisition radar, and 9S32MK ABM engagement radar, both part of the S-300VMK system. The drawing includes the NK Orientir precision navigation system, but shows no datalink mast for dispersed TEL operation.

The newest station can be part of the S-500 air defense system, although in reality this locator is a much more universal reconnaissance tool. The Yenisei radar station, which entered service with the Russian army, is designed for continuous operation for a long time. For example, the S-400 Triumph radar systems (a command post radar system and a multifunctional radar station of an anti-aircraft missile battalion) were not originally intended to function for such a long period, since anti-aircraft battles and battles do not take place for long hours and days.

It is this feature of the Yenisei that makes it possible to receive reconnaissance information for a long time, which is important for the means of conducting radar reconnaissance. At the same time, the operator's error factor is practically excluded - the radar works, as they say, in full automatic mode. Yenisei is a fully digital locator, its antenna is an active phased array. In addition, the radar is an active-passive device, it can conduct reconnaissance and detect air objects and issue target designations to air defense fire weapons even without broadcasting. That is, "Yenisei" has the functions of conducting electronic intelligence. In particular, information on targets from the Yenisei is issued to the multifunctional radars of the S-400 and S-500 anti-aircraft missile systems.

In 2021, a contract was to be signed for the supply of the S-500 air defense system, since all the components of the system were already ready. As for the S-400 air defense system, the Yenisei (along with the 96L6 all-altitude detector) is already included in this system.

The Yenisei locator is equipped with remote posts, which allows it to successfully deal with jammers. For example, the success of the US Air Force's actions in many local conflicts was ensured by the fact that practically all air defense systems of Washington's opponents were suppressed by powerful and well-organized interference. But this does not apply to the Yenisei. The higher the interference intensity, the better the locator ties the target tracks and more accurately gives target designation to air defense fire weapons. So with the adoption of the Yenisei by the Russian Aerospace Forces, the United States, one might say, lost this trump card.

Another feature of the Yenisei radar is that the locator can operate in a sector (recall that most radar reconnaissance equipment operates in a circular view mode). This characteristic allows the radar to successfully issue target designations for ballistic missiles. By the way, the 96L6 all-altitude detector (VVO), usually attached to the S-400 air defense system, cannot work in the sector.

The characteristics of the "Yenisei" interested the leadership of the anti-aircraft missile forces of the Russian Aerospace Forces. So, the radar complex (RLK) 92N6 of the command post of the S-400 anti-aircraft missile system operates "round-the-clock". But it is the continuous and long-term work of the Yenisei in the sector that will sharply increase the effectiveness of anti-aircraft missile defense against ballistic missiles in missile-hazardous areas. Therefore, in the anti-aircraft missile forces at the positions of the command post of the S-400 air defense system, two locators are installed at once - the standard 92N6 S-400 radar and the Yenisei radar.

In addition, the Yenisei well “sees” and accompanies its launched anti-aircraft guided missiles and can very accurately determine whether the target has been hit in the event of a meeting. This feature of the locator really liked the leadership of the air defense missile forces of the Aerospace Forces. Now, with the help of the Yenisei, they can assess the effectiveness of the anti-aircraft missile units.

"Yenisei" provides the issuance of target designations for hypersonic targets. And this system has another remarkable feature. For example, the missile of the Iskander-M operational-tactical complex first rises to a great height (about 100 km). Then, on the descending part of the trajectory, it begins to actively maneuver. This makes it almost impossible to intercept it.

Moreover, on the way to the target, the Iskander missile releases carbon threads, which leads to a complete illumination of the enemy radar indicator screens, that is, there is such an abundance of false targets that any effective operation of the enemy's anti-aircraft missile systems on such missiles becomes simply unrealistic. Russian sources laim that the United States had not developed any effective method of confronting the missiles of this complex.

Yenisei “sees” such targets, can steadily accompany them and issue precise target designations on them. In addition, Yenisei is able to effectively combat atmospheric phenomena, the so-called "angels". They arise mainly over water surfaces and cause a strong illumination of the indicator screens (in the form of a large number of false targets) of both detection radars and missile guidance stations. In particular, the Chinese came face to face with them after purchasing the S-400 air defense system and placing their starting positions near water surfaces. Domestic experts have made effective protection (by various kinds of algorithmic tricks) and from "angels", including on the Yenisei radar.

Also, the Yenisei is equipped with built-in state identification means, both domestic (the Guardian system) and NATO MK-12 (the latter may be of interest to foreign customers). In addition, the locator also has a secondary channel for operation in the EU ATC (unified air traffic control system) in the range of 1030-1090 MHz. This allows the Yenisei to have complete information about the civilian aircraft currently in the air.

The Yenisei radar is highly maneuverable. The coagulation / deployment time does not exceed 5 minutes. To increase mobility, outriggers (outriggers), which, for example, have, for example, VVO 96L6, were removed from the Yenisei. This radar still has mechanical "paws" for leveling, but they are already being put forward in a rut, without being extended.

Yenisei detects airborne objects at altitudes of more than 100 km (on the border of space and air space), at ranges over 600 km, steadily accompanies them and is a universal and multifunctional tool for detecting a variety of airborne objects and issuing precise target designations to fire weapons air defense.
