Thanks for your valuable post.. much appreciated..

Q2. I also want to know how does S-400 protect itself against jamming?
@hellfire you listening? Any theories?

Any ABM system/defensive system can be overcome on so called saturation.

What is the value? That is classified. What is pertinent is what @Skull and Bones has said - the number of missiles your adversary is willing to use.

Beyond that, the stratification of defence system will be required. No system is 100% foolproof.

Thats all I can say

X-band radars wrt RCS ...

The 92N6 Grave Stone multimode engagement radar is a significant redesign of the Flap Lid / Tomb Stone series with fully digital processing and increased power-aperture performance (image © Miroslav Gyűrösi).

The diverse Flap Lid family of radars are Russian equivalents to the US MPQ-53 Patriot engagement radar. The first generation of the S-300P's 5N63 (later 30N6) Flap Lid A engagement/fire control radar was innovative, and clearly influenced by the Raytheon MPQ-53 engagement radar for the MIM-104 Patriot. The Flap Lid, like the MPQ-53, uses a transmissive passive shifter technology phased array, with a space (a.k.a. optical) feed into the rear plane of the antenna. The Flap Lid's antenna stows flat on the roof of the radar cabin, which was initially deployed on a trailer towed by a Ural-357, KrAZ-255 or KrAZ-260 6x6 tractor. The whole radar cabin is mounted on a turntable and used to slew the phased array to cover a 60 degree sector of interest.

The 5N63 was a huge generational leap in technology from the Fan Song, Low Blow and Square Pair mechanically steered and scanned engagement radars on preceding V-PVO SAMs. With electronic beam steering, very low sidelobes and a narrow pencil beam mainlobe, the 30N6 phased array is more difficult to detect and track by an aircraft's warning receiver when not directly painted by the radar, and vastly more difficult to jam. While it may have detectable backlobes, these are likely to be hard to detect from the forward sector of the radar. As most anti-radiation missiles rely on sidelobes to home in, the choice of engagement geometry is critical in attempting to kill a Flap Lid.

Unlike the Patriot's MPQ-53 engagement radar which has substantial autonomous search capability, the 5N63 is primarily an engagement radar designed to track targets and guide missiles to impact using a command link channel. The absence of dedicated directional antennas on this system indicates that the commands are transmitted via a specialised waveform emitted by the main array. The first generation of the 5V55K missile was command link guided, following the design philosophy of the S-75/SA-2 and S-125/SA-3, with a cited range of 25 nautical miles and altitude limits between 80 ft and 80,000 ft.

Growing US electronic combat and SEAD capabilities, in the EF-111A Raven and F-4G Weasel forces were clearly considered a serious threat and this spurred the further evolution of the S-300PT system. In 1982 the V-PVO introduced a fully mobile variant of the system, designated the S-300PS (P- PVO, S - Samochodnyy/Self-propelled), labelled by NATO the SA-10B. The S-300PS saw the 5N63 Flap Lid engagement radar transplanted on to the high mobility 8x8 MAZ-7910 vehicle derived from the MAZ-543. The rehosted radar became the 5N63S Flap Lid B (Samochodnyy/Self-propelled). This permitted the engagement radar and TELs to set up for firing in 5 minutes, and rapidly scoot away after a missile shot to evade US Air Force Weasels. The improved 5N63S Flap Lid B radar had the capability to concurrently engage six targets, and guide two missiles against each target. The phased array beam steering angular range was extended to permit instantaneous coverage of a 90 degree sector, comparable to the SPY-1 Aegis radar.

The next big evolutionary step in the S-300P system was the introduction of the enhanced S-300PM and its export variant the S-300PMU1/SA-10D, in 1993. The SA-10D, later redesignated SA-20 Gargoyle, was subjected to what Russian sources describe as a deep modernisation with design changes to most key components of the system. The aim was to improve its basic capabilities as a SAM, extend radar and engagement footprints, increase the level of automation in the system, and introduce an anti-ballistic missile capability against ballistic missiles with re-entry speeds of up to 2.8 km/sec. Incremental changes were made to the Flap Lid, yielding the 30N6/30N6-1 Tomb Stone variant, designated 30N6E1 for export, capable of guiding the new 48N6 missile, the manufacturer claims an ability to engage targets with an RCS as low as 0.02 square metres at an unspecified range, and an autonomous search capability. The 30N6E1 retains the capability to deploy on the 40V6M mast.

Further evolution of the S-300P design took place between 1995 and 1997, yielding the S-300PMU2/SA-10E Favorit system, later redesignated SA-20 Gargoyle, intended to compete directly against the Antey S-300V and Patriot PAC-2/3 systems as an Anti-Ballistic Missile system. The Favorit incorporates incrementally upgraded 30N6E2 Tomb Stone engagement radar. The Favorit's new command post has the capability to control S-300PMU / SA-10, S-300PMU1 / SA-20 batteries, and also S-200VE/SA-5 Gammon batteries, relaying coordinates and commands to the 5N62VE Square Pair guidance and illumination radar.

The most recent derivative of the S-300P family of systems is the S-400 Triumf or SA-21. The 30N6E2 further evolved into the more capable 92N2E Grave Stone, carried by a new 8 x 8 MZKT-7930 vehicle. The additional range required a significantly uprated transmitter tube to provide the higher power-aperture performance needed, in additional to an improved exciter and automatic frequency hopping capability.

The dual plane monopulse circular polarised primary feed has been stripped and the concertina shroud has deteriorated. The operator consoles are in the F2 module, typically located on a truck. Later self-propelled 5N63S Flap Lid B variants retained the capability to deploy the F1S module on the 40V6M/MD mast, with the F2S module remaining attached to the MAZ-7910 8x8 vehicle chassis (© 2009, Said Aminov).

The 64N6E Big Bird is the key to much of the improved engagement capability, and ballistic missile intercept capability in the later S-300P variants. This system operates in the 2 GHz band and is a phased array with a 30% larger aperture than the US Navy SPY-1 Aegis radar, even accounting for its slightly larger wavelength it amounts to a mobile land based Aegis class package. It has no direct equivalent in the West.

Like other components of the S-300PM system, the 64N6E has a number of unique and lateral design features. The radar antenna is mounted on a cabin, in turn mounted on a turntable permitting 360 degree rotation. Unlike Western phased arrays in this class, the 64N6 uses a reflective phased array with a front face horn feed, the horn placed at the end of the long boom which protects the waveguides to the transmitters and receivers in the cabin. The beam steering electronics are embedded inside the antenna array, which has around 2700 phase elements on either face. This Janus faced arrangement permits the Big Bird to concurrently search two 90 degree sectors, in opposite directions, using mechanical rotation to position the antenna and electronic beam steering in azimuth and elevation. This design technique permits incremental growth in output power as the only components of the system which have to handle high microwave power levels are the waveguide and feed horn.

The 64N6E is a frequency hopper, and incorporates additional auxiliary antenna/receiver channels for suppression of sidelobe jammers - NIIP claim the ability to measure accurate bearing to jamming sources. The back end processing is Moving Target Indicator (MTI), and like the Aegis the system software can partition the instantaneous sector being covered into smaller zones for specific searches. To enhance MTI performance the system can make use of stored clutter returns from multiple preceding sweeps. Detection ranges for small fighter targets are of the order of 140 to 150 nautical miles for early variants. Per 12 second sweep 200 targets can be detected, and either six or twelve can be individually tracked for engagements.

While the Big Bird provides an excellent acquisition capability against aerial and ballistic missile targets, the 5V55 missile was inadequate. The S-300PM/PMU1 introduced the 48N6 which has much better kinematics - cited range against aerial targets is 81 nautical miles, ballistic missile targets 21.5 nautical miles, with a minimum engagement range of 1.6 to 2.7 nautical miles. Low altitude engagement capabilities were improved - down to 20 - 30 ft AGL. The missile speed peaks at 2,100 metres/sec or cca Mach 6. The missiles can be fired at 3 second intervals, and Russian sources claim a single shot kill probability of 80% to 93% for aerial targets, 40% to 85% for cruise missiles and 50% to 77% for TBMs.

The latest variant is the 91N6E developed for the S-400 Triumf / SA-21 system. It is known to be a fully digital design with a higher peak power rating than the 64N6E2 to accommodate the longer ranging 48N6E3 and 40N6E missiles.

The new 91N6E is a derivative of the 64N6E Big Bird series. It is readily identified against the 64N6E by the use of the new build MZKT-7930 tractor. It retains the general configuration of its predecessors (Almaz-Antey).

how many more threads Indians will open on s400 for god sake stop this drama...

Your problem is?

His inferiority complex is acting up.

 

[samy1618]

And still every one is saying about S450 and 6000 missiles.. But no one over here has a credible source or info about the same. As I have heard that China is have the same 5 S-400 for just 3 billion and India for whooping 6 billion... R we going crazier day by day like we shell off 8 billion for just 36 Rafael and still there r speculations of secret deals for Full TOT including tech know how, machining n tooling, scientific data. and lot many more. So r we following the same path for S-400 by shelling off more than it cost.
Plz can any one have a full heads up on this... As its more suspicious than French as India did many covert deals with Russia earlier also on many fronts. And I think here ppl know what all I am pointing at.

 

[Qutb-ud-din Aybak]

india needs s 400 as it needs large country to protect. pakistan can protect itself completely using other systems with low range.

Later.

Wait for it and till then, buy only those systems that have achieved a single real kill. You might like to look up Patriot missiles and Tomahawk cruise missiles.
