55ZH6M "Nebo-M" TALL RACK Mobile multi-band radar complex

The 55ZH6M "Nebo-M" is a mobile radar complex of medium and high altitudes using radar of various types in a block-modular design. According to the R & D "Nebo-M", the creation of an interspecific radio-location station [RLS] for detecting air targets in a wide range of wavelengths was carried out.

Drones, ballistic missiles, planes and even those employing stealth technology can’t hide from the Nebo-M. It’s a mobile radar station that spots and tracks airborne targets with two radar systems operating in different frequency ranges. The Nebo-M consists of three trucks carrying a giant, swimming-pool-sized antenna, a smaller one, and a command post module. Together they scan airspace at a range of 1,800 km and an altitude of 1,200 km. The Nebo-M takes just 15 minutes to deploy and its mobility enables positioning in any required direction. It also has strong jamming protection and works even if its radar systems get knocked out.

In the framework of the R & D "Sky-M" NIIIRT, work was underway to create a mobile interspecific multi-band radar location complex [RLK] of medium and high altitudes based on the BAZ-6909 chassis. The RLK is designed to detect prospective means of aerospace attack: aircraft, hypersonic cruise missiles, ballistic missiles, etc. RLC 55ZH6M implements significant detection zones for small-sized and inconspicuous targets, including made using the "Stealth" technology, a short lead time for high-speed targets, a high rate of updating and issuing information, incl. on speeding and maneuvering targets, long-range detection of launches of ballistic missiles, large ceilings in the mode of tracking ballistic targets.

The RLK is made in the form of a meter-decimeter-centimeter complex, which provides for the operation of radars of different wavebands, not independently, but in adaptive interaction, allowing to combine the advantages of different wavelength ranges. RLK is made on the block-modular principle and contains a set of radar modules (RLM) meter, decimeter and similar in design, centimeter wavelengths, as well as, control cabins RLM work and their interaction.

The “Nebo-M” mobile multiband radar system is capable of detecting small-sized aerodynamic and hypersonic targets in difficult EW environment and bad weather conditions. It is also able to send data to the missile defence combat units. The system has Active Electronically Steered Array antennas which allow to work in difficult jamming situation that is why it is capable of detecting targets at larger distances and performing a quicker transmission of radar data concerning ballistic and hypersonic targets. Fully automatic data processing, target classification, functional-diagnostic monitoring and inquiry and communications systems allow to reduce the size of crew. At present, the radio-location complex [RLK] includes four radar modules of various ranges, controls and power supply. All radar modules are mounted on the BAZ-6909-015 chassis with the wheel formula 8x8 and carrying capacity up to 22 tons. NNIIRT Nebo M System Components"

  1. KU - Central track processing and fusion system with multiple operator consoles.
  2. RLM-D - Self-propelled AESA radar based on L band Protivnik G design
  3. RLM-S - Self-propelled AESA radar based on S / X band Gamma S1 design
  4. RLM-M - Self-propelled AESA radar based on VHF band Nebo SVU design. Nebo-M RLM-ME is a 3-D acquisition radar. It is the successor to the 1L13 Nebo “Box Spring” and is easy to distinguish from it since the direction of polarization is vertical rather than horizontal. The system can be deployed or stowed in 40 minutes.

VHF-band and the L-band components are available, and it is not necessary to complete the Gamma S1 / S1E. The KU vehicle in the suite is the operator van. Each vehicle has an independent generator rated at 100 kiloWatts. It has been noted that the system will be able to complete the system. All radars are designed to ensure that they can be used in the field.

The Nebo M Mobile Multiband Radar System uses the BAZ-6909-015 8x8 all terrain 24 tonne chassis, self-propelled by BZKT BAZ-6909-015, is used as the SA-21 5P85TE2 TEL and the proposed wheeled SA-23 variant. S-300PMU1 / 2, S-400 and S-300PMU systems, hosted on the BAZ-6909 S-300P / S-400 missile battery. NNIIRT 3D radars, the VHF band and the S / X-band Gamma S1 were designed for the 55Zh6 Nehir SVT AESA design. The L-band component antenna has been reduced size compared to the semi-trailer hosted 59N6E radar.

It is a clear idea that it provides a counter-VLO capability. A track fusion system in the KU vehicle will be required, providing a capability of the Navy CEC (Cooperative Engagement Capability) system. This technology was previously developed. It is a controlled leakage pattern. It is a very significant advancement to make it possible.

Carlo Kopp noted in 2010 that the newer NNIIRT-designed 1L119 Nebo SVU and Nebo M RLM–M radars are self-propelled and designed from the outset to support SAM batteries in the field. The Nebo M RLM–M is the much more powerful and accurate self-propelled offspring of the Nebo SVU. Using a similar but much larger hydraulically deployed and stowed AESA design with 168 active elements, this system is carried on the same 8×8 all-terrain BAZ–690915 chassis as SA–21 SAM system launchers. It provides around 40 percent more range and much more accurate angle measurement than the Nebo SVU, retaining the electronic beam steering agility of its predecessor.

Kopp observed tat the RLM–M is a formidable modern radar in its own right. It is intended for use as part of the Nebo M multiband counter-stealth radar system, which employs the VHF-band RLM–M, the L-band RLM–D, and the S-band RLM-S AESA radars, all networked together via the RLM–KU command post. What is not stated in the Russian-language PowerPoint slides is that by default, this system must incorporate a radar track fusion capability.

Kopp stated that it has capabilities similar to the recently introduced U.S. Navy Cooperative Engagement Capability (CEC) system. Proper deployment of the Nebo M would see the VHF-band radar painting incoming stealth aircraft head on and the flanking L-band and S-band components painting the target from the often less stealthy sides. Also unstated is that with an operational networked “CEC-like” track fusion system resident in the RLM–KU command post, other more potent configurations with multiple radars are feasible—for instance, networking and fusing tracks from several RLM–M or RLM–D systems.

Kopp argues that Russian VHF-band counterstealth radars will become a major operational issue for the future U.S. fighter fleet as the size of these aircraft precludes effective shaping in the VHF-band. Many VHF radars will be able to track stealthy fighters at tactically useful distances, albeit much smaller compared to legacy fighters. A fighter’s ability to survive is then determined by its ability to deny launch opportunities through speed and altitude, evade any launched SAMs through high turn rate maneuvering, and compromise terminal SAM seeker guidance by stealth and electronic countermeasures.

Kopp states that the F–22A Raptor is in a strong position because its high penetration altitude and supersonic cruise capability place it out of reach of all but the best long-range SAMs. Its stealth is effective from all key aspects, and its shaping is well designed to defeat threat radars from the Ku -band down to the L-band, negating all but the VHF-band radars. The aircraft’s high supersonic turn rate maneuver capability will provide it with an excellent ability to spoil SAM endgame maneuvers. The aircraft is large enough to accommodate internal electronic countermeasures equipment for endgame self-defense.

The new generation radar system aimed to perform missions of air defence and radar support of the anti-aircraft missile troops in difficult jamming situation was shown at the exposition of the Aerospace Defence forces at the International military and technical forum “Army-2015”, which was held June 2015 at the premises of the “Patriot” park for cultural and recreational activities of the Russian Armed Forces (Kubinka, Moscow Region).

Nebo-M - Program

The work within the framework of the R & D project "Sky-M" began in the late 1990s. In 1999, a decision was made to place large-sized system modules on the chassis of the Bryansk Automobile Plant. Initially it was planned to develop an early warning RLSC with characteristics approximately corresponding to 55ZH6, but with increased mobility. Later, radar modules of the decimeter and centimeter ranges were included in the RLC 55ZH6M.

In 2008, a prototype of the built-in ACL module (ROC "Nebo-M") was fully manufactured. In 2008, the first stage of the preliminary tests of a prototype of the 55Zh6M radar as part of the meter radar module RLM-M and the control cabin of the KU RLK was completed with a positive result. In 2009, ground tests were carried out and a prototype of the 55ZH6M radar in the configuration of the RLM-M, RLM-D and KU RLK with the built-in ACL module created by a separate ROC was presented for state tests.

According to Protocol No. 13 dated March 18, 2010, summing up the results of the tender for the supply of a prototype RLK, the competition was held by the Ministry of Defense of Russia, the winner - NIIIRT. In 2010, the first stage was completed and the second stage of the state tests of the prototype according to the design work "Nebo-M" was started, the stage of updating the working design documentation according to the results of the first stage of state tests was completed.

The new generation radar system aimed to perform missions of air defence and radar support of the anti-aircraft missile troops in difficult jamming situation was shown at the exposition of the Aerospace Defence forces at the International military and technical forum “Army-2015”, which was held June 2015 at the premises of the “Patriot” park for cultural and recreational activities of the Russian Armed Forces (Kubinka, Moscow Region).

In accordance with the State Defence Order, two radio-technical regiments, Western Military District, located in Leningrad region and Karelia, received latest Nebo-UM radars. The Nebo-UM is a modernized version of the Nebo-U radar. The radar is intended to survey the air space, locate various targets and define coordinates. The station can locate and track down aircraft and cruise missiles, as well as ballistic targets.

Crews of S-400 air defense systems have destroyed air targets at the Ashuluk proving ground, the Defense Ministry said on 28 September 2017. "During a tactical exercise the crews of air defense and radio-technical forces and a division level command post practiced redeployment to the Ashuluk proving ground and counter-measures against an enemy air raid and carried out launches of missiles against targets," the ministry’s news release runs. Taking part in the exercise were crews of the S-400 missile systems, radars Nebo-M, Kasta 2-2 and Podlyot.

Neb-M requires half as many people as the old complex, since the new radar has fully digital automatic data processing, and the complex is able to classify targets. Specialists of the Center for the training of anti-aircraft missile forces VKA them work on the calculations for these radars . Mozhaisky. The educational complex "Nebo-M" has been operating there since 2013, more than 250 people have trained there. Four radar stations "Nebo-M" and "Nebo-UM" in 2015 began work in Transbaikalia, Khabarovsk and Primorye.
