    F-22 having frontal RCS of 3m^2 or more in the X-Band? Are you out of your mind?

    Sukhoi realizes how difficult it is to track the F-22 which is why they are inserting L-band radar within the leading edge of the PAK-FA and maybe even the Su-35S.

    The radar power equation is proportional to 1/range^4 and only linearly proportional to RCS. However at very low RCS it becomes difficult to distinguish a signature from noise.

    It is only difficult to track F-22 using the Western radar of its typical short wavelength, or using the nose mounted radar which is very small in size and cannot use long wavelength due to the decreased resolution.

    But for Russian-type ground radars, no, F-22 can't escape.

    The theorem is that if F-117 was shot and RQ-170 was caught. Then F-22 has no hope to survive, either.

    Stealth cloak of F-22 is merely a sextoy to make the fanboy reach climax. It is useless against Russian radars, at least ground radars.

    Define irony. And yet you do not understand why Sukhoi is inserting L-band radar within the leading edge of the PAK-FA/Su 35S.

    Re RQ 170, Iranians know a dick about RCS. The RQ 170 had a power plant failure  and crashed in Afghanistan. Shia groups loyal to Iran took it across the border.

    Haha, cool bs story.

    Stealth drone in Afghanistan...who you with your bullshit sources want to bullshit?

    It was used over Iran, they catched it with russian Avtobaz EM vehicle and landed it on their airfield, they know much about RQ-170 RCS, this little RQ-170 is the reason why Iranians had such a leap jump in aviation technology of their own build up Military Industrial Complex. The US first denied, they used a stealth drone over iran, then Iran showed it to the public and Obomba the clown immidiatley started to threaten Iran with sanctions for "STEALING" the RQ-170, the iranians took several weeks to study it and now they have enough knowledge to build their own.

    But cool story...Afghanistan... Laughing

    Nick,

    Ask someone that has some free time to explain to you why the above assertion of yours proves that you don't even have an elementary school understanding of anything.

    Forget about radars, RCS, airplanes, ...; everything you said about them was gibberish; just "think" about this basic fact that an equation is never proportional to anything, never.

    The reason why Russia put the L-band radar on its wings is because the nose of a fighter aircraft is small and you cannot put on that nose a big radar for utlizing L-band or lower wavelength ones to strip off the stealth cloak.

    But ground radar can.

    And the 10-metre radar on the wing of T-50 also can.

    Why do you need L-band radars to be large in the first place? L -Band radar permits good long range search performance with modestly sized antennas.L-band offers an additional economy, as a single L-band design can combine conventional primary radar functions with secondary IFF/SSR functions, thus saving considerable antenna and transmitter/receiver hardware weight, cooling and volume.

    I think you know full well that radar resolution decrease with the longer wavelength and increase with the antenna size. Without a sufficiently big radar you cannot provide enough resolution for long wavelength like L-band, VHF, or lower.

    The nose-mounted radar cannot be very big (biggest one is MiG-25/31's with 1,4 metre diameter). But the 10 metre wing radar of T-50 is enough to use L-band to strip off the sextoy cloak of F-22.

    Meanwhile the ground radars have a lot of space to be big. 10 metre, 20 metre, or more. More than enough to use L-band or VHF. Even radars of the old man SAM-2, SAM-3 had already use L-band to track the aerial target. Even in Vietnam, 150 MHz radar is not something rare.

    In short, you beloved F-22 is just a sextoy. Its only function is make the fanboy reach climax.

    That is the difference between a datalink and a radar.... a datalink can be relatively small because it is not directional and doesn't care where the signal comes from.

    A radar on the other hand uses the signal it emits to find the location of the target.

    L band radar will detect stealth fighters at max range, while the powerful nose mounted x band radar will detect it at reduced ranges.

    I read somewhere that F-22 has around 30 antenna smoothly blended into the wings and fuselage ,anyone knows about that ?

    That's various antenna, i guess most of them are part of ALR-94 RHAWS.

    Don't forget, that MiG-31 also have L-band elements in its Zaslon radar and were used in combination with AA-6 AAMs. As I know MiG-31BM keep them in its Zaslon-AM radar, although MiG-31BM doesn't use AA-6 anymore. Su-35 and PAK-FA will also be equipped with L-band AESA complex, so I think this L-band complex will be connected with new long range AAM RVV-BD as all those fighters are meant to use long range AAMs with ~300 km range. Majority of self defense jammers are for X-band, not for L-band, so those new missiles will have better capabilities in heavy ECM environment comparing to X-band ARH AAMs and better capabilities to engage stealth planes.

    Great find Medo, few more pics here on RP.net:

    Apparently 7 borts passing through Perm. Wonder where are they going.
    PS: think i found it, they are going to Lipetsk and will be part of the parade, also Su-30SM will take part.

    Is there going to be a pause in su-35 procurement for ruaf? We're some 6-7 months away from the original order of 48 planes being fulfilled. So far no new contract has been published. Since one needs to secure long lead items for production, some taking 18 months before the airframe is contracted, it seems plausible to me that either A) there's already been a new contract signed but it was made secret
    or B) contract has not been signed and some additional batch of su-35, even if the contract is signed tomorrow, is not due to be handed over to ruaf before end of 2017.

    If true, it also might signal a preplanned action, where knaaz has its production facility reserved for foreign buyer during a period where ruaf pauses in its procurement. It'd also require a full contract signed in secrecy already.

    But in that case ruaf would find itself in a position where it chooses to produce more su35 perhaps up to 2020, and have pak-fa being produced in numbers alongside it.

    Russia to Unveil New Su-35 Fighter Engine at Paris Air Show

    Rostec will demonstrate an engine for its famous Sukhoi Su-35 at Le Bourget, the company said on Monday.

    LE BOURGET (Sputnik) — Russia's state technology corporation Rostec will showcase an engine for its famous Sukhoi Su-35 (Flanker-E) at the world’s oldest air show in France, the company said on Monday.

    Some 37 Russian organizations are expected to be among 2,000 participants from 46 countries at the week-long 51st Paris Air Show at Le Bourget Airport kicking off on Monday.

    "We expect the professional community to devote a lot of attention to the AL-41F1S (Izdeliye 117S) engines installed on Russia’s multifunctional Su-35 fighter aircraft," a corporate representative told RIA Novosti.

    The new engines, it was explained, are intended to serve as transitional engines for fifth-generation jet fighters and will be manufactured by a Rostec subsidiary, the United Engine Corporation (ODK).

    The Paris Air Show will feature a 1-3 scale mockup of the bypass turbofan engine with a thrust-vector-controlled afterburner designed for Su-35/35S jets.

    The Su-35 fighter was first introduced to a foreign audience at the Paris Air Show in 2013 as a heavily upgraded derivative of the Su-27 multirole fighter touted as "4++ generation."

    The 4++ designation signifies that the Su-35's combined characteristics, with the exception of stealth capabilities and active electronically scanned array (AESA) radars, bridge it closer to the fifth generation fighter.

    They're coming close to the end of the first contract. Aready 34 planes delivred on 48 ordered: so it would make sense if they went for 48 more planes soon.
