    There is a mix of brand new weapons like KAB-250 and Kh-38, and modified older weapons like late model Kh-31s and Kh-58 and Kh-35 as well as R-77, 9M100, and R-37M etc.

    Don't think Kh-31 will be carried (externally anything is possible ofc), Kh-58UShK is made specifically for internal storage IMO.

    They showed the Kh-31 with the Skat and the latter had no external weapon hard points.

    The Kh-31 with folding fins should be able to be carried internally... it is quite long though.

    The Kh-58 was slightly shortened and fitted with folding fins to make it compatible with the PAK FA and the original is about 4.8m

    The Kh-31 is 4.7m long in its earlier versions, but I assume if they shortened the Kh-58 they could shorten the Kh-31 too if they needed to.

    The older TV guided 1,500kg bombs like KAB-1500Kr, KAB-1500Kr-Pr, and the KAB-1500Kr-OD are about 4.6m long while the newer laser guided KAB-1500LG-F-E, KAB-1500LG-Pr-E, and KAB-1500LG-OD-E are just under 4.6m long so I would suspect they would fit... or could be modified to fit.

    Is there any proof, article, photos that the right and left ones are indeed weapon bays(in addition to centreline ones) which will carry missiles? Sorry I haven't followed PAK-FA progress for some time.

    Russia to Showcase 5-G Fighter at AF Festival

    Russia will display its much hyped fifth-generation fighter prototype, the T-50, at an air show in August, according to a document posted on the official legal information portal http://pravo.gov.ru on Friday.

    The jet, as well as other warplanes, including the Tupolev Tu-95MS, a modification of the Tu-95 Bear strategic bomber, will be shown at a festival dedicated to the 100th anniversary of the establishment of Russia’s Air Force, on August 11-12 near the town of Zhukovsky in the Moscow Region.

    The fighter was first shown to the public in August 2011, also in Zhukovsky, at the MAKS-2011 air show.

    The T-50 made its maiden flight in January 2010 and two prototypes have since been undergoing flight tests.

    The T-50, developed under the PAK FA program (Future Aviation System for Tactical Air Force) at the Sukhoi experimental design bureau, is Russia's first new major warplane designed since the fall of the Soviet Union.

    It is expected to enter service in 2016.

    Good news.

    I wonder how many we will see there?

    Hope they are dealing with the cracking problems.

    Given that the PAK FA might itself be up against Air Defence batteries using C-D band radars, what sort of ‘nano-particles’ will absorb these longer wavelength signals. Wouldn’t this have to be either rather thick, or else heavily iron-loaded polymer ? How does this equate with reducing drag ?

    IRST is of little value in cloud, fog and rain .IRST would be unable to distinguish targets at dawn and dusk.

    Just some of my concerns about the PAK FA , which I hope Sukhoi will address before the PAK FA goes into production.

    Well we can have the "RAS" or RADAR Absorbing Structure to the sensitive part of the PAKFA.

    And well with today's advanced computers.. Stealth fighters may need lesser RAM materials than earlier gen.. the shape of the PAKFA can be optimized (and likely so) to counter those band (but well within possible size limit)

    Well in 12.000 m however.. altitude where BVR may usually take place (lesser drag on missile and more efficient engine performance).. there's no cloud nor dust to hamper IRST from acquire its target from 80km++

    The classic Western approach to stealth is 80 % design , 20 % composites. Since the PAK FA is designed to be super maneuverable therefore more emphasis has to be put on composites than design . Which means the entire aircraft has to be covered by the composites.

    BVR is not altitude dependent . Long range missiles have their own set of problems. The problem with BVR missiles is that the distance the target can move after the missile leaves the aircraft and arrives to an interception area to scan for targets is quite long. In most cases the eventual fight will be WVR .

    Sorry, what?

    Stealth is either 100% design or it is nothing (ie low observable LO and not stealth).

    If stealth was only 80% design then you would need to design stealth aircraft from scratch... you could modify the shape of an existing type... you can't if you want real stealth.

    Real stealth is 100% design and RAM... composites have nothing to do with stealth and everything to do with reducing weight.

    All composite gliders are not radar invisible stealth aircraft.

    For composites to replace structural components they have to be strong... at least as strong as the components they are replacing or they would be pointless.

    Don't confuse composites and stealthy addons like RAM they are NOT the same thing and are not even related.

    Covering a conventional aircraft with a composite skin will not make it stealthy... in fact even if those composites were like the radar domes of fighter aircraft and were fully radar transparent making them the outside skin of an aircraft would mean the careful shaping design of the outer skin of the aircraft that is designed to refract the radar energy in all directions except the direction the original signal came from would not work. If the outer skin of the aircraft that was carefully shaped and carefully made to extreme tolerances was radar transparent how could its shape effect the beam of incoming radar energy and redirect it so it does not return to the radar that emitted it?

    A radar transparent skin would let the radar energy enter the aircraft and hit the internal structure and equipment and engines and the pilot inside the aircraft which have not been carefully shaped for stealth so any radar could pick the aircraft up from hundreds of miles away...

    The opposite of stealth.



    BVR is not altitude dependent . Long range missiles have their own set of problems. The problem with BVR missiles is that the distance the target can move after the missile leaves the aircraft and arrives to an interception area to scan for targets is quite long. In most cases the eventual fight will be WVR .

    The high ground advantage applies in air combat more than in any other arena.

    A BVR missile fired from a subsonic aircraft at sea level is not a BVR missile unless it has a very very long range.

    For instance a late model sidewinder has a range of 18km or so at medium height but at low altitudes its effective range is less than 5km.

    High altitude high speed launch gives your missiles maximum energy for their max range.

    BVR missiles have very difficult times with long range shots, but most very long range weapons can get updates from launch aircraft... and for it to turn into a WVR battle then the target needs to keep closing all the time during which BVR missile shots are more likely.

    Also IRSTs are not Thermal Imagers and can easily detect targets through clouds... clouds reflect all visible wavelengths of light... which is why they look white, that doesn't mean they block all IR light too.

    Stealth 101


    Stealth is either 100% design or it is nothing (ie low observable LO and not stealth).

    Stealth is Low Observable . True, some aircrafts like the Typhoon and Super Hornet are marketed by their producers as LO. So the buyer gets the impression that they are purchasing a "Stealth Aircraft" at the cost of a legacy ( 4th gen) aircraft .

    Real stealth is 100% design and RAM... composites have nothing to do with stealth and everything to do with reducing weight.

    All composite gliders are not radar invisible stealth aircraft.

    Low observable properties are obtained by incorporating the radar absorbing material into the louver structure rather than the use of more traditional and higher maintenance surface coatings. Radar absorbing intake structures can be designed to absorb electromagnetic energy over multiple bandwidths.
    Stealth technology had begun with coatings that reflect less radar than the aluminum commonly used on airplanes. In fact, the now thirty-year-old SR-71 reconnaissance aircraft made use of radar-absorbent coatings to help lower the risk of detection.The airframe stealth geometry is only a partial answer for the contemporary radar development. Only the centimeter and millimeter long radar waves are effectively deflected by such method while the L-band radars remains a treat.


    Don't confuse composites and stealthy addons like RAM they are NOT the same thing and are not even related.

    While it's true that all composites are not RAM , all RAM are bound to be composites.


    Covering a conventional aircraft with a composite skin will not make it stealthy... in fact even if those composites were like the radar domes of fighter aircraft and were fully radar transparent making them the outside skin of an aircraft would mean the careful shaping design of the outer skin of the aircraft that is designed to refract the radar energy in all directions except the direction the original signal came from would not work. If the outer skin of the aircraft that was carefully shaped and carefully made to extreme tolerances was radar transparent how could its shape effect the beam of incoming radar energy and redirect it so it does not return to the radar that emitted it?

    The word "STEALTH" has been sold to such an extent by US defense contractors that even till this date many countries believe that the F 22 & F 35 are indeed INVISIBLE to radar. Nothing could be further from the truth . An object that is the size of a marble in S Band radar will be the size of a tennis ball in VHF band radar . While it's true that a composite skin will not make an aircraft stealthy , neither will shaping . However, composites especially those that Irkut is using for the Super Sukhoi program are nano-metric anti-radar covering that are much more light and stable. It's made with magneto-dielectric layering 2-80 nm thick on a high temperature-steady material. The radar-absorption is about 10 Db in 8-80 GHz diapason . Its relative mass is as 1 – 1.5 kg/m2. High resistance against climatic factors is provided. They have just one-layer structure instead of the usual 5-6.RCS can now be brought down by almost 10 times .



    Also IRSTs are not Thermal Imagers and can easily detect targets through clouds... clouds reflect all visible wavelengths of light... which is why they look white, that doesn't mean they block all IR light too.

    Thick clouds act like a wall to the infrared energy. Even wavelenghts beyond IR like Micro wave can see through clouds with limited accuracy. In IR , clouds appear in varying shades of gray (false color) as they depend on temperature which depends on height. IR and Visible Light are next to each other in the Electromagnetic Spectrum (IR is close to the Red of Visible light). Therefore , just like Visible Light , IR too is unable to see through clouds or water vapor.

    You can't separate stealth from marketing...

    LO is a 4+ gen fighter with some stealth features intended to reduce detection range in an attempt to achieve an edge in air to air combat with non LO aircraft.

    Stealth is the attempt to design and aircraft from scratch that is difficult to detect and track.

    A LO is not Stealth and Stealth is not LO.

    Low observable properties are obtained by incorporating the radar absorbing material into the louver structure rather than the use of more traditional and higher maintenance surface coatings.

    Radar absorbing materials are not strong enough to be used as structural components. Composites are strong enough, but are not radar absorbent.

    On LO aircraft features are adapted to be stealthy, but only achieve LO rather than actual stealth performance.

    Stealth has to be designed from scratch to be very low RCS... you can't just take any design and redesign the intakes and put a bit of RAM on it to make it stealthy.

    Radar absorbing intake structures can be designed to absorb electromagnetic energy over multiple bandwidths.

    The difference between VHF radar and X band and even K and Ku band radar is rather significantly more than the difference between (visible) light and heat. For longer wave radar like VHF shaping doesn't work because the waves are so long it can't detect shaping features less than 5-10m in size.

    Stealth technology had begun with coatings that reflect less radar than the aluminum commonly used on airplanes.

    Stealth is not about absorbing all the radar energy, most of stealth is about shaping to redirect the energy so it does not return with any strength back to the emitter. The F-117 was made largely of Aluminium... it didn't get its stealth from materials, it quite clearly got it from sophisticated shaping and high tech fabrication that was able to make a plane within the tolerances of a few mms.

    In fact, the now thirty-year-old SR-71 reconnaissance aircraft made use of radar-absorbent coatings to help lower the risk of detection.

    Yeah... they constantly bragged about that, and claimed the U-2 was not able to be tracked by the Soviet radars too... was largely wishful thinking in reality.

    When the SR-71s flew missions over Vietnam old obsolete radars in China tracked them from takeoff to landing... you don't need an engineering degree to pick out its very distinctive flight profile and speed performance.

    There is no evidence EVER of the Soviets or the Chinese ever having problems tracking the SR-71.

    The airframe stealth geometry is only a partial answer for the contemporary radar development. Only the centimeter and millimeter long radar waves are effectively deflected by such method while the L-band radars remains a treat.

    Except that CM and MM wave radar is the primary search/detection/tracking radar frequencies used today in fighter aircraft, anti aircraft missiles (ground and air launched). Stealth wont make you invisible, but it does make it harder to engage you and limits the types of weapons that can be used.

    This is reflected bluntly for the F-22... its only weapons are AMRAAM, older model sidewinder, and a cannon. AMRAAM will have serious trouble getting a lock on a PAK FA and older model sidewinders will have problems with DIRCMs which means F-22s will be relying on their guns to engage PAK FA aircraft.... the PAK FA on the other hand will have a range of passive homing IIR guided AAMs developed for it including 9M100 Morfei. Past practise has been for the medium range missile to carry the seeker of the short range missile (ie the R-27T and R-27ET had the IR seeker of the R-73 fitted, and I have no reason to think they wont continue the practise..)

    The word "STEALTH" has been sold to such an extent by US defense contractors that even till this date many countries believe that the F 22 & F 35 are indeed INVISIBLE to radar.

    I use the word stealth to imply designed from scratch to have a low RCS with internal weapons carriage etc. LO is RAM coatings and minor edge and corner reflector management to reduce RCS but with external carriage of weapons and applied to an existing design.

    An object that is the size of a marble in S Band radar will be the size of a tennis ball in VHF band radar .

    A better example would be the F-22 itself... in X band it is claimed to have insect sized RCS performance. In the visible light band however it is an F-22 sized reflector... which changes based on the angle it is observed from.

    While it's true that a composite skin will not make an aircraft stealthy , neither will shaping .

    Of course it will. Look at a B-2... from above it is substantial and easy to see, but flying towards you edge on it is a much smaller target and much more difficult to see.

    A radar transparent outer skin will reveal the internal structure of the aircraft to external radar sources... with all its corner reflectors and bits and boxes...

    However, composites especially those that Irkut is using for the Super Sukhoi program are nano-metric anti-radar covering that are much more light and stable.

    Composites with RAM incorporated into their internal structure should still be shaped to redirect radar away from an emitting source. Having it incorporated in the material the aircraft is made of should make it much more durable and prevent the problems with the F-22 which has external coatings that need to be removed to get to access panels. The very high maintainence of the F-22 is because to get to an access panel to correct a problem or replace a component you have to sand off the RAM and remove the tape around the panel and then fix the problem and then replace the panel and tape it up and then apply the RAM and let it cure and then paint over it.

    In contrast the F-35 uses RAM embedded in the skin.

    Thick clouds act like a wall to the infrared energy.

    There are several bands of IR energy that can travel efficiently through the atmosphere, they have longer waves than visible light. The longer bands require the sensor to be cooled and is much less effected by water vapour.

    One of the suggested uses for thermal imagers that operate in bands above the IR seekers of missiles... in a similar band to IRSTs, is to improve visibility when driving in Fog.

    Now tell me I am wrong but Fog is water vapour isn't it?

    I accept that IR sensors can't see through liquid water or glass, but like radar it has a fairly wide range of freqencies with different properties... very short wave radar is useful as a weather radar because it can track water vapour and therefore be used to determine wind speed etc.

    Even wavelenghts beyond IR like Micro wave can see through clouds with limited accuracy.

    Microwave ovens work by effecting water molecules in food and creating friction, which generates heat.

    IR and Visible Light are next to each other in the Electromagnetic Spectrum (IR is close to the Red of Visible light).

    UV light is next to X rays, but UV light does not penetrate your skin like X rays do...

    Delays and challenges for Indo-Russian fighter

    Seven years before its scheduled completion, the Ministry of Defence (MoD) has already announced a two-year delay in the Fifth Generation Fighter Aircraft (FGFA) India and Russia are to jointly develop.

    Defence Minister A K Antony has been saying the FGFA would join the Indian Air Force by 2017. On Monday, his deputy, M M Pallam Raju, told Parliament, “The fifth generation aircraft is scheduled to be certified by 2019, following which the series production will start.”

    The FGFA is the flagship of the Indo-Russian partnership. Both countries say it would be the world’s most advanced fighter. But interviews with Indian designers who have overseen the project suggest significant disquiet. There is apprehension the FGFA would significantly exceed its current $6 million budget, because this figure reflects the expenditure on just the basic aircraft. Crucial avionics systems would cost extra.

    On the positive side, Indian designers say the FGFA project would provide invaluable experience in testing and certifying a heavy fighter aircraft that is bigger and more complex than the Tejas light combat aircraft (LCA), India’s foundational aerospace achievement.

    The Russian and Indian air forces each plan to build about 250 FGFAs, at an estimated cost of $100 million per fighter. That adds up to $25 billion each, in addition to the development cost.

    The FGFA’s precursor has already flown. In January 2010, Russian company Sukhoi test-flew a prototype called the PAK-FA, the acronym for Perspektivnyi Aviatsionnyi Kompleks Frontovoi Aviatsy (literally prospective aircraft complex of frontline aviation). Now, Hindustan Aeronautics Limited (HAL) will partner Sukhoi to transform the bare-bones PAK-FA into an FGFA that meets the Indian Air Force (IAF)’s requirements of stealth (near-invisibility to radar), super-cruise (supersonic cruising speed), networking (real-time digital links with other battlefield systems) and world-beating airborne radar that outranges enemy fighters.

    But Sukhoi insists the PAK-FA already meets Russia’s requirements, says N C Agarwal, HAL’s design chief, who spearheaded the FGFA negotiations until his recent retirement. HAL worries Russia might ask India to pay extra for further development, particularly the avionics that transform a mere flying machine into a lethal weapons platform. That would leave the $6-billion budget in tatters.

    The IAF clearly wants a top-of-the-line FGFA. According to Ashok Nayak, who spoke to Business Standard as HAL’s chairman before retiring last October, the IAF has specified 40-45 improvements that must be made to the PAK-FA. These have been formalised into an agreed list between Russia and India, the Tactical Technical Assignment.

    A key IAF requirement is a ‘360-degree’ AESA (airborne electronically scanned active) radar, rather than the AESA radar that Russia developed. Either way, India would pay Russia extra: either in licence fee for the Russian radar; or hundreds of millions, perhaps billions, for developing a world-beating, 360-degree AESA radar.

    Nor is the IAF clear on whether the FGFA should be a single-seat fighter like the PAK-FA, or a twin-seat aircraft like the Sukhoi-30MKI. A section of the IAF backs a single-seat fighter, while another prefers two pilots for flying and fighting a complex, networked fighter. During the ongoing preliminary design phase (PDP), for which India paid $295 million, the two sides would determine whether developing the PAK-FA into a twin-seat aircraft (inevitably more bulky) would reduce the FGFA’s stealth and performance unacceptably.

    “The single-seat FGFA is essential for the IAF, and we will transform the Russian single-seat fighter into our single-seat version with a large component of Indian avionics. The twin-seat version will depend on the PDP conclusions,” says Nayak.

    The PDP also requires Sukhoi to hand over design documentation to HAL, providing it a detailed insight into the design processes of the PAK-FA. Since India took years to decide to join the FGFA project, HAL missed out the design phase entirely.

    The 18-month PDP, which terminates this year, will be followed by the ‘R&D phase’, which could take another seven years, says the HAL chairman. The FGFA would be designed in both countries. About 100 HAL engineers already operate from a facility in Bangalore. Another contingent would move to Russia to work in the Sukhoi design bureau.

    “Our boys will learn the Russian language, their way of working, their design rules and their design norms. We are left-hand drive, while they are right-hand drive. The Russians say they would part with all these things,” says Nayak.

    But the most valuable learning, say HAL executives, would take place during the FGFA’s flight-testing. “Unlike the basic design phase which we missed out on, we will actually gain experience during flight testing. This phase throws up dozens of problems, and we will participate in resolving these, including through design changes,” says Agarwal.

    HAL designers also relish the FGFA’s specific challenges. For achieving stealth, its missiles, rockets and reconnaissance payloads are concealed in an internal bay under the wings. Before using these, a door slides open, exposing the weapon for use.

    The Russians clearly believe HAL possesses useful capabilities, including the ability to design the AESA radar. Also attractive is India’s experience in composites.

    “The LCA programme has generated a high level of expertise in composite materials within the National Aerospace Laboratory and some joint teams. The FGFA requires ‘higher modulus’ composites, which can withstand the 120-130 degree Centigrade temperatures that arise whilst flying at Mach 1.7 speeds,” says Agarwal.

    Despite the continuing imponderables, HAL believes the FGFA project provides genuine technological skills, far more useful than licensed manufacture. Agarwal says, “We will pay some $6-7 billion to France for the licence to build the Rafale in HAL. In the FGFA project, a similar sum would bring in genuine design knowledge that will help us in the future.”

    Now, Hindustan Aeronautics Limited (HAL) will partner Sukhoi to transform the bare-bones PAK-FA into an FGFA that meets the Indian Air Force (IAF)’s requirements of stealth (near-invisibility to radar), super-cruise (supersonic cruising speed), networking (real-time digital links with other battlefield systems) and world-beating airborne radar that outranges enemy fighters.



    Where does this nonsense come from?
    Article in general is full of innacuracies, and general perceptions that don't match reality.

    He is worried that the Russians might charge India more than $6 billion dollars for the secrets to building a 5th generation stealth fighter aircraft?

    After admitting that is about what they are paying France for Rafale secrets I would think Russia should be obliged to charge more.

    I would expect the FFGA will be very much like the Su-30MKI, though the financial situation in Russia has changed and instead of the Russians having to fly Su-27s while Indian pilots fly Su-30MKIs it will be more of a case of the Russians flying Su-35s and Indian pilots flying Su-30MKIs.

    I suspect there are a few bits the Russians might not want to give away to anyone and so they will "develop" alternatives with India... or perhaps India will outsource the items...ie EW stuff from Irael etc.

    India’s Version of Sukhoi T-50 Delayed by Two Years

    The joint Indo-Russian project to produce a fifth-generation fighter aircraft (FGFA) for the Indian Air Force is facing a two-year delay. It will now take nine years instead of the stipulated seven to develop. The Indian Air Force attributes the delay to Hindustan Aeronautics (HAL), which has a workshare of 25 percent in the program.

    The two-seat FGFA is based on the single-seat Sukhoi T-50 PAKFA. HAL is tasked with supplying designs for the tandem seating and cockpit displays, none of which have been provided on time, a senior air force official told AIN. HAL is also responsible for navigation and countermeasure dispensing. Indian junior defense minister MM Pallam Raju recently confirmed the delay to Parliament, commenting, “The fifth-generation aircraft is scheduled to be certified by 2019 [instead of 2017], following which series production will start.” India and Russia concluded the $295 million preliminary design contract for the FGFA project in December 2010, during Russian President Dmitry Medvedev’s visit to India.

    There are also concerns the FGFA will exceed its current estimated $6 billion development budget. The unit production price is predicted to be between $93- and $97 million. India will acquire 214 aircraft, making the total cost of the FGFA project at least $26 billion.

    The 30-ton FGFA will be “a swing-role fighter with highly advanced avionics, giving 360-degree situational awareness, stealth to increase survivability and smart weapons,” said now-retired Indian Air Force Chief P.K. Naik. Capable of covering long ranges without refueling, it will feature supercruise along with advanced mission computers. The Indian Air Force has specified 43 improvements to the design following its observation of flying trials at the Zhukovsky airbase.

    Fourth T-50 Stealth Fighter to Fly This Year

    Russia's United Aircraft Corporation (UAC) is to introduce a fourth Sukhoi T-50 stealth fighter into its test and development program this year, the company's President Mikhail Pogosyan said on Thursday.
    "We are now testing three aircraft. A fourth will be brought in this year," he said.
    Pogosyan had said earlier this year that the firm would introduce a fourth aircraft into the test program but did not disclose when.
    The first production standard T-50 is due to enter service with the Russian Air Force by 2015, and the first evaluation example by 2013. The service plans to acquire 60 of the fifth-generation fighters.
    The T-50, also known as project PAK-FA, first flew on January 29, 2011 and was first publicly revealed at the Moscow Air Show in August that year. India will also acquire an advanced fighter aircraft based on the T-50.

    This one seems to have taken a little longer than they probably expected, but they had cracking and some other issues to deal with.

    I rather suspect if this new prototype solves the problem they will ramp up production to make 6 more in the next 2 years. They said a while ago that they were going to make 10 flying prototypes so they could get through the testing program rapidly.
