    Ken:
    You can arrive at the 10,000 kg fuel load for the MKI if you assume that the volume of the No.4 fuel tank is the same as the one on the Su-35. i.e 1990 liters. Page 283 second column, 1st paragraph. Thats 4020 + 5030 + 1350 + 1990 (instead of 1270) = 12,690 liters. That with Fuel Density of 0.785= 9,961.65 or 38.35 kgs short of the 10K mark. This ties in with the table on Page 303 and what Harry has posted.

    Ken could you tell us a bit more about Andrei Fomin? I only know bits and pieces about him. So who is he? Whats his relationship with Sukhoi OKB and KNAAPO/IAPO? How much cooperation did he get while writing this book? What more does he bring to the table about th Flanker over Jon Lake’s work?

    I ve been treating this book as a bible coz i was told to do so ……

    Crobato:
    What applies to the MKK also applies to the MKI. The veil of secrecy is equally stringent as the BR correspondents who wanted to get close to this bird. Incidentally has anyone ever gotten close enuf to the PLAAF MKK/SK/UBK on this board or anywhere? If not then its kinda ironic …….

    Well how many countries on this planet can afford the ‘luxury of war’ ? I can only think of one…but thats another story:) .

    You gotta be a ‘resource optimizer’ in this economy unless your economy is driven by war….but that too is another story 😀 .

    Thats a bit sweeping since the report linked only referes to the MKK using the Sapsan which itself seems to be refed from Michal Fiszer and Jerzy Gruszczynski, ?Eyes of the eastern eagles: fire-control systems for Russian tactical strike aircraft,? Journal of Electronic Defense, February 1, 2003 p. 38

    Anyone else seen Sapsan-E before AI03?

    The first AWACS wont come for the next 48 months or so. For an AWACS to effectively work it has to be well integrated into existing air defence and communication systems. This is a very big task given the logistics involved in India. Hence even if AWACS is inducted in 4 years its not gonna be operationalized instantly.

    In 4 years (2008) there will be max of 24 HAL MKI, 50 IAPO MKI (incl. the 18 MK to be upgraded to full MKI std).

    Thats barely 75 ‘quality’ airframes and I think in the same 4 years the number of flanker derivatives in the neighbourhood will go up from the current 250-270 to at least 300.

    Besides wont the A-50 be operational by that time too?

    I m very curious about the the Sapsan-E. I didnt even know about it until Harry posted a pic from Aeroindia 03 on ACIG. Is it in development or is it already in production?

    Victor:

    Oh and one more reason for going upto 60 sqd.

    From one of the new AFM threads:

    Sukhoi had by early this year delivered 154 aircraft to China, mainly comprising Su-27SK fighters. Adding these to the newly acquired Su-30MK2s and Su-27SKs built locally in Xinjiang, China, will mean that 273 advanced Sukhoi fighters will be in service by the end of the year.

    ……….

    China bought 50 Su-27 fighters worth $1.7 billion from Sukhoi over the period 1991-97, including 38 single-seat Su-27SKs and 12 twin-seat Su-27UBKs.

    In 1996, Beijing paid $2.7 billion to acquire a licence to produce 200 Su-27SK aircraft from component packages and the Xinjiang assembly facility has so far received 95 of these component kits. However, a contract covering the additional 105 kits has yet to be concluded.

    In 2000-02, China received 28 Su-27UBK operational trainers in repayment of Russian debt.

    Sukhoi exported 38 Su-30MKK multirole twin-seat fighters worth $1.5 billion to China in 2000-01. Last year, Sukhoi finished implementing a second contract involving 38 Su-30MKKs.

    In this light 190+ MKI variants dont seem much.

    2006 is the most viable date. The earlier quoted ‘end’ of 2004 is unlikely given that initial contract of 32 MKI are not yet done with.

    I dont think in 2006 HAL will be making MKI from scratch. It will be the usual CKD to SKD to complete indeginization route. Given the deep license nature of the MKI program, HAL will have a very steep learning curve with single crystal turbine blade etc and given the learning curve its very difficult to gauge the rate of mastery and indiginization of every MKI components.

    The MKI Bars is a monster. The antenna diameter is 1m. The current Zhuk have a diameter of 624mm or 0.62m in the Mig-29 nose, doesnt that mean the Bars would also be a sub meter antenna. Wont that affect its performance?

    Victor:

    Nope its merely an inference. Given that:
    1) MKI is joint development program unlike previous Russian a/c.
    2) MKI still have many more iterations to go.
    3) MKI has started incorporating Project Vetrivale components.
    4) MKI will be built by HAL @ 10-12 a/c over 12-14 years.
    5) MKI are 2002 vintage.
    6) IAF likes to keeps it a/c for well over 20 years.
    7) You dont go from 40 sqd to 60 sqds in over a decade by increasing your transport fleet. You buy more of what works. More M2K/LCA/MKI.
    8) And IAF needs to goto 60 sqds if it intends to be percieved as serious player with ‘global’ reach.

    The IAPO built MKI was to cost about $33M
    The HAL built MKI will cost about 10% less.

    Yep and this is ‘friendship price’ for ordering ‘freindship quantities’ of 190 + MKI.

    Also as its been often reported but seldom comprehended the MKI is a PROGRAM rather than a one off PURCHASE for the IAF/IAPO/HAL. This means the price per unit is not really a good metric since the first MKI’s which arrived in Sept 02 would be significantly cheaper (without upgrades) than the second batch which would be cheaper than the third and so on.

    If the talk off core avionic computers and composites is to be believed the HAL MKI will cost a bit more than the IAPO MKI. Note the only real savings would be in labor costs not really in the components.

    The pictures posted by SOC are the IAF Su-30K not the MKI. Further they all seem to be SB 00X (eg. SB004 and what looks like SB006) these belong to the first batch of 8 planes recieved by the IAF in circa 1997. These have been acknowledged as modified Su-27PU. This makes the aircrafts as a 10 hard point variety and NOT the 12 hardpoint variety that we have been discussing. I think this can be explained by the ‘missing’ hardpoints 11 and 12 : the innermost wing pylons.

    Aerospacetech:
    Thats a good question one reason could be that points 11 and 12 are not hardwired ‘yet’ for the R-73, even though Fomin talks about 6 R-27’s being carried by either the 10 pointer or the 12 pointer, the R-27ET seems to be compatible with only points 3 and 4 in his diagrams but yet even the IAF SB004 seems to carry them all over the centerline and under the engine ???

    Like many things about these fine machines this one too shall remain a mystery to me.

    Not all R-27 are created equal. Hence they dont weight the same the diff can be upto 100 kgs.

    I dont know where you sourced your info from but i sourced mine from Adrei Fomin. If you have a better source it would be nice to know.

    Not all pylons are created equal (at least not on all the Su-30 derivatives) each has a different loading and recognition of the ordinances. Case in point is the R-73 which is the lightest of all the R’s and yet is not carried in the innermost wing pylons.

    Will post a detailed yes/no to your after you clarify the source.

    Sure it can carry ‘upto’ 6 KH-31 A’s (on 4, 12, 10, 9, 11 and 3) then it can also carry 2 more RVV in points 1 and 2 and four R-73’s on 8, 6, 5 and 7.

    What about R-27??? Well you wanted to maximize on the KH’s and now you have taken over the same hardpoints on which the R-27 ET’s can mounted? If you still want to carry the R-27 ET then you will have to drop 2 KH from 4 and 12 and substitute them with R-27 (ET). (the ER’s go on the same hardpoints as the RVV’s/KH but ET’s go on only 4 and 12)

    So if you want to load out 6 KH and 2 RVV and 4 R-73 (R-27’s hardpoints are taken by KH and RVV) and ALL THIS IS BELOW the max payload then more power to you.

    If the 610 Kg weight of the KH-31 A is correct then thats 3660 Kgs from that, each of the two RVV-AE weights 175 kgs thats 350 kgs right there (total 4010 kgs) and the four R-73’s (105 Kg each) come in at 420 kgs to push the total to 4430kgs. Thats well below the 8 T payload.

    The moot point is: just because you can carry 6 KH assuming you need 6 KH loadout, are two RVV-AE and 4 R-73 enough for a ‘self escorting role’ for a loadout that requires 6 KH? Or do you need R-27’s too? In which case you drop down to 4 KH, 2 RVV, 4 R-73 and 2 R-27 (ET @ 250 kgs each or ER @ 355 kgs each). You can be at this all day long. Or do you have several assests with a preponderance of KH and some with a preponderence of R’s and you have a mixed package.

    In a nutshell………it depends on your tactics and training.

    Oh and before I forget this discussion is centered around the KH-31 AShM which i believe is the KH-31A and not the P (anti radiation), Fomin claims that the Kh-31A has a launch range of 50km thats well withing SAM range. Sure you can also carry the Kh-59M it has a range of 100 km but it weighs in at 920 kgs and Su-30 derivatives can only carry two of them and it has to use one hardpoint for the Tekon (the guidance pod). Oh and its not supersonic either. I am too tired to do the math of this one but i guess you guys get the idea.

    I dont think the MKK can carry 6 KH-31A and RVV-AE (R-77).

    Adrei Fomin thinks that the Su-30 (12 hardpoint variety) can carry ‘upto’ 6 KH-31A on hardpoints 4, 12, 10, 9, 11 and 3. The same a/c can also carry upto 8 RVV’s on hardpoints 4, 12, 10, 1, 2, 9, 11 and 3. Also if you throw in the R-27ER/R-27ET and R-73 you are gain hardpoints 8, 6, 5 and 7 but are also now competing for hardpoints all the RVV hard points. (please note that each hardpoint also needs a different adapter (APU-470 or AKU-470 for the R-27’s and the APU-73 for the R-73) to carry the ‘SAME’ ordinance, so its not a plug and play kind of deal). Dont get me started on the KAB 500/1500. And all this has to be under 8T.

    Hence the effective loadout will have to be an optimal mix of what the mission dictates and what the strike package looks like.
