March 23rd American aviation Aviation Week magazine published an analytical article by renowned experts Carlo Kopp and Bill Sweetman about Russia’s plans to counter US stealth air attacks (the material is cited with some abbreviations).
The article says that the delay in adopting the F-35 gave Russia more than 20 years to prepare for its appearance. In terms of the development of fighter aviation, Russia chose three types of combat aircraft, two of which are direct development of the Su-27. The lighter MiG-29 / 35 are offered for export only.
Of these three aircraft, the Su-34 fighter / medium bomber is the most mature. The first batch of six aircraft arrived at the center of combat use in Lipetsk, another 10 must be transferred during this year. As it was announced by 1 in March, 2020 Su-92 will be added to 34 by the year of the Air Force. These aircraft should replace the outdated Su-24. The purpose of the Su-34 is to strike at land and sea targets, suppress / destroy the enemy's air defense system and other tasks.
The second is the Su-35 air superiority fighter. On January 17, the third prototype of the Su-35С, made in serial configuration, took off. Previously, one of the two prototypes was destroyed during a run on the runway. According to Sukhoi, 400 test flights were made with prototypes, state acceptance tests began in August 2011, upon completion of the construction of the first production aircraft. Su-35S is equipped with an advanced digital control system and engines with variable thrust vectoring, which made it possible to abandon the front horizontal tail assembly (PGO), similarly installed on the Su-30MKI. The front plumage imposed restrictions on the maximum speed of the Su-30MKI (total Mach 1,8). Reducing the empty weight has increased the stock of domestic fuel, the aircraft has "exceptional maneuverability." The power plant consists of two XDUMXС TRDDFs with increased by 117%. The effective scattering area (EPR) of the aircraft was reduced using 16's technologies developed by ITAE. All these capabilities allow the Su-1990 to have a smaller radar signature, modern air combat missiles are developed in response to the AMRAAM and Meteor MBDA SD.
The third type is the fifth generation fighter T-50. Analysis of the photo and video of the third prototype suggests that this sample is equipped with on-board equipment that will ensure the operation of the radar and other sensors. It is reported that the prototypes performed 100 flights. The aircraft was developed on the basis of early designs with a wide center section, where internal compartments are located. T-50 has a so-called. movable part of the influx (PCP) and small turning vertical keels of a small area. Engine nozzles can deviate up and down from the vertical in 30 degrees.
There is one question that does not have an answer yet. Is the existing T-50 configuration final or will it be finalized? The plane has “uncovered” round nozzles of engines with large infrared radiation, air intakes do not have S-curvature, which would hide the blades of the engines and reduce the radar signature.
As asymmetric measures against US military aviation, ground-based air defense systems such as radars with very low unmasking signs and ultra-long-range anti-aircraft missiles are being developed, and new-generation short-range air defense systems are being developed to combat anti-radar and cruise missiles, guided by air bombs. These mobile systems have a very short combat deployment time (no more than 5 minutes, which allows them to quickly change their combat positions, moving away from the enemy aviation’s retaliatory strike).
The focus is on the development of radars operating in the meter VHF range. The fact is that modern stealth technologies are largely ineffective in this wavelength range, since the stabilizers and wingtips of aircraft are in size close to this range of radio waves. The leader in the development of such stations is NRIIRT, which has developed a three-band 55-X6 “Nebo-M” radar. Russian Air Force ordered 100 such stations. "Sky-M" is a complex of three radar stations RLM-M (VHF range), RLM-D (L-band) and RLM-S (C / X-band), information and command modules hosted on 8- axle 24-ton trucks. All radars have antennas with active lights. RLM-M is used to detect unobtrusive targets, RLM-D and RLM-S are intended for their tracking and missile guidance. The target detection and tracking range is not reported, but, as expected, the RLM-M range is at least 40% more than the previous Sky-SVU station.
The 1L118E “Sky-SVU” station with AFAR VHF range developed by the same company, apparently, was not built in large quantities. This radar was placed on a "less mobile" semi-trailer. In 2002, the chief designer of the radar station, Igor Krylov, stated that "we see stealth (F-117A) as clearly as any other aircraft."
A promising integrated system of aerospace defense of Russia is supposed to be created around the strategic system of air defense C-400 "Triumph" (SA-21 Grouler), as well as the missile defense system C-500М "Triumphator" (SA-X-NN). The C-400 shelves are currently located in Dubrovka, Elektrostal and Vladivostok.
The C-400 is a development of the C-300PMU2 (SA-20B Gargoyle) air defense missile system, retaining the X-band radar and standard tubular transport and launch containers for missiles. The complex is equipped with a digital multi-mode radar 92H6 and advanced combat control radar 91H6E, developed on the basis of 5H64 / 64Н6Э / Э2. Launchers are placed on semi-trailers based on a 8-axle all-terrain vehicle BAZ-6909. The upgraded 48H6Х3 / DM rocket used on the C-300PMU2 has a target range increased to 250 km (155 miles). Soon a new 400H40 rocket with a range of 6 km will come into service with the C-400. Belarus will become the first foreign operator C-400.
At the same time, the C-300B4 system is being developed, which is a further development of the C-300B (SA-12 Giant / Gladiator) troop-level air defense system (S-9 Giant / Gladiator) with the American missile missile Sprint. ZRK will receive upgraded tracked chassis and 82М9М and 83М2500М missiles designed for the Antey-200 system (range, respectively, 250-120 and 130-300 km). It is still unknown whether Russia on the C-4B9 will replace the 32C9 radar with an improved 32XXNUMXM radar with a larger area of radar.
The “upper tier” of the East Kazakhstan region will be represented by the C-500 system, which is under development. Information about this system is not enough, but in the middle of 2010, there were reports that the C-500 anti-missile will be created based on the 9М82М anti-missile with an increased range of 500-600. The C-500 will be equipped with combat control radars of the 91Н6А type (M), tracking radar 96Л6-CPU, new multimode radar 76Т6 and radar PRO 77Т6.
