    @Vanir

    The other document doesn’t fit your description of composite content for the Eagle, maybe they just didn’t define graphite/epoxy as composites there?
    And for that matter I haven’t argued about the Su-27 baseline model featuring any composites at all, I just raised doubts with regards to your claim that 65% of the Su-27s structure would be based on titanium. Aluminium-lithium is extensively used as well afaik. But I have no exact split for the different materials either.

    What nonsense? I am putting things into the right perspective. If you say something, then say the complete information, just just the cropped out part that suits you. It’s OK to say that F-16E is more advanced than 29SMT but without mentioning that it costs more than twice as much and that it only exists because of rich vendors from UAE who paid all this expensive theater the information is misleading.

    I didn’t compare anything else than the time frames when those airframes were available. I personally stick with the given facts, rather than creating what if scenarios as they have no relevance in the real world, especially not if we talk about the past which has gone.

    A much more interesting debate would be what Americans could have done with Russian budget, if you ask me.

    If labour costs would have been similar to that of Russia maybe, but as said I’m not really interested in the what ifs at all.

    Yes, I know that. The 961 and 967 are exactly like you described. The only question remains whether they represent the future series version or Russians just stick to what is available now.

    There were a couple of articles released over the years in issues of AFM, AI or CA etc. You can also take a look at the manufacturers site, which should shed some light for you on the topic:

    Why speculating if the facts are in front of us 😉

    @EELightning,
    I don’t share the view of the F-35 being a dedicated striker, it’s a multirole fighter with emphasis on AG, but not focused on it only. Their final conclusion is mine as well, it doesn’t matter what label you apply, it matters whether the aircraft meets your requirements. Except for the exeggerated F-35 bashing I share their view to a large extend and if someone reads my comments in past topics concerning generations you’ll find a lot of them in there as well. The reference point for a new generation isn’t another new generation system in the first place, but a previous generation system. The VLO aspect is downplayed however, though it’s spot on that the US defines a 5th generation fighter close to what is claimed there, this includes supercruise and high agility. In the end everyone tries to layout things the way they suit them best.

    I have to agree with Mrmalaya that its of course marketing with a lot of hype and propaganda, but that’s natural. Important is what you can extract on information besides the hype and there isn’t much relevant in this issue.

    @Mrmalaya,
    the Rafale was never really a subject of Eurofighter commercials, with the exception of the last issue with regards to the UAE events. In this issue they even claim (page 10):

    through to the best representatives of fighter class aircraft on the market, the Rafale and the Eurofighter.

    It’s about precise control and workload. The MiG-29 is certainly not “hard” to fly as such, but more challenging to fly than the F-16 for example. An experienced Fulcrum jockey should have no trouble to fly the aircraft to its limits and make use of its performance potential. A beginner might have a harder time and in total the MiG-29 requires more active flying which requires attention and subsequently substracts from the pilots situational awareness. It might not be relevant in all situations and its impact is possibly relative small, but it adds up with other weaknesses such as the less capable radar, the more difficult control of the systems due absence of real HOTAS controls and limited data presentation due the dated cockpit layout. It’s not like the MiG-29 is so difficult to handle that it is hopefully outperformed. In dogfight situations this more difficult handling may have a smaller impact as the pilot has to permanently control the aircraft anyway. In formation flying, aerial refueling and other situations it’s certainly more recognisable.

    In short words:
    More active steering+aero limits awareness & monitoring = more difficult to handle

    Good question why they didn’t install it before. Or maybe the systems onboard the Su-34 are to power hungry and don’t allow the engines to be started with it?
    The weight is about 40 kg according the link MSphere has provided.

    @Haavarla,
    if the Su-34 is dependent from external supplies for engine start it is somewhat unlikely that it features an APU at all in its current form.

    Reminds me on my old graphic of a fantasy fighter. It must be at least 8 or more years old.

    @Vanir,
    this is from an article about the F-15 family I have saved on my HD.

    The aircraft has an all-metal semi-monocoque fuselage of 58 feet 3 inch in length. The fuselage is of conventional semi-monocoque construction, and has a central pod and lateral twin-boom configuration. The F-15 airframe contains 25.8 percent titanium by weight, most of it concentrated around the engines and in the inboard sections of the wings. The three main wing spars and the bulkheads connecting them and the frames of the engine pods are of titanium. Aft of the forward main wing spar, the fuselage skin is also of titanium. The cantilever booms outboard of each engine which carry the twin fins and horizontal stabilators are made of titanium, as are the stabilator attachments and the spars of the fins. There is a titanium firewall between the two engines to prevent a fire in one engine from spreading to the other.
    The heart of the aircraft structure is a set of four carry-through frames which run across the central fuselage, each with holes cut into them to allow the engine air intake ducts to pass through. At each end, they form the main attachment points for the wings, the three aft frames being attached to the three wing spars, and the forward point attaching to a leading-edge member. Machined titanium frames in the rear fuselage maintain structural integrity and provide the main mountings for the engine installation….
    …The tail unit of the F-15A is an all-metal structure consisting of twin fins and rudders made of boron composite skin over honeycomb material.

    This document http://ftp.rta.nato.int/public//PubFullText/RTO/MP/RTO-MP-069%28II%29///MP-069%28II%29-%28SM1%29-01.pdf claims 2% composites only for the F-15E, 49% aluminium, 32% titanium and 17% of other materials.

    MSphere,
    what kind of nonsense are you talking about here? We talk about aircraft which exist and not the what if, what could have been etc.
    You could as well argue what the Russians could have done with the budget of the US in the meantime…

    Edit:
    There were a couple of articles from Piotr Butowski etc. which talked about the development history of the new generation Fulcrums. The land based models lack the tail hook, upbeefed landing gear and afaik folding mechanism and larger inner flaperons. The rest of the structure is said to be identical, including the enlarged wings.

    It would, just not in the form as we know it today, but much closer to MiG-29M2 (with Zhuk-ME or maybe MFE PESA). Malaysia was a possible territory once but they opted for the MKM instead.

    The MiG-35 is not based on MiG-29K/KUB, that’s completely wrong. It is based on MiG-29M2.. The first MiG-35 prototype was directly rebuilt from MiG-29M2 MRCA (154) which was nothing else than a rebuilt MiG-29M prototype from early 90s. The lineage is clear and there are no K/KUB involved there.

    Carrierborne variants have separate lineage, although the first MiG-29Ks (single-seaters) shared the lightweight lithium airframe concept with deleted overwing louvres with the MiG-29M and later MiG-29K/KUB inherited the twin-canopy solution from MiG-29M2. So they look very similar, but they are different aircraft.

    Austrians received several offers, the last one was for MiG-29SMT-IIs. They even tested the prototype (917) in Zeltweg, some pics were posted on airliners.com.. IIRC, the offer for bulk aircraft was around $15mil a piece which sounds pretty unbelievable to me. Even with the well-known Fulcrum issues regarding shorter service life, it was a good bang for the buck, I’d say.

    While it is true that the first MiG-35 demonstrator was converted from the MiG-29M2, which was based on the 4th MiG-29M prototype (Bo.No. 154) it was just a demonstrator for the avionics. A new built aircraft was simply not available at that time and the MiG-29M2 was a logical choice for a first demonstrator.
    Yet RAC MiG decided in 2002 to develop a unified family of single and twin engined land- and carrier based aircraft. This came after the evaluation of the MiG-29M2 showed that its new canopy wouldn’t affect the performance of the aircraft. As Indian was supposed to order the K it was ultimately decided to base the entire family on the KUB.
    The M was to be based on the K, but India requested a different avionics fit with more advanced sensors such as an AESA radar this led to the MiG-35.
    If you take a look in the recent RuAF news thread you’ll see that recent MiG-35 prototypes (961 & 967) are converted from previous MiG-29K/KUB.

    There wouldn’t have been a MiG-35 in the form as it is now, so what’s the argument about another M based Fulcrum being possible earlier, while it would have nothing to do with the MiG-35 in its current form now?

    Btw. The MiG-29M/M2 was offered for more than 30 mln $ to Austria.

    The name Typhoon was originally created on 2nd September 1998 specifically for export customers outside of Europe. It was not before 23rd July 2002 when the RAF adopted the name itself. No other customer uses the “Typhoon” designation, except for Saud Arabia where the aircraft is called Typhoon FGR.50 in its current form.

    @Vanir,
    the RuAF has put the ex Algerian MiG-29SMT/UBT into service and the IN just received its first MiG-29K/KUB a few weeks ago. They might not be mature yet, but they are certainly operational and subsequently no technology demonstrators.

    With regards to the content of titan and composites, the Su-27 uses titan and steel but not to such a large extend. Teens don’t use a great content of composites either F-15s, F-16s and F/A-18s make use of not more than single digit percentage of composites often less than 5%. The Super Hornet is an exception with 19% of composites. The sources about the PAK FA are varying here titan is said to make up 20% only, while composites are said to be used for 70% of the surface.

    I don’t discuss here whether the MiG-29 is as good for export customers as western export fighters, but many of the major weaknesses have been eliminated on the newer variants such as the MiG-29K which is in service right now and so far the most developed and advanced variant in service.

    @MSphere,
    the MiG-35 couldn’t have been in service years ago. The defining features of the MiG-35 are all avionics related and this aircraft is based on the MiG-29K/KUB designed for the IN, but with various avionics options. The same is true for the MiG-29M which was offered with most of the stuff fitted to the MiG-29SMT2 or K. There was an offer in late 2002 from the Russians to Austria for the MiG-29M which was rejected and which was much based on the old MiG-29M airframe.

    I wonder why the Su-34 has no APU when even the baseline Su-27 has one. I was of the impression those aircraft had one, but that article was a little bit confusing.

    I think both sides put forward some valid arguments. Good posts from Vanir and djcross. Technology evolves and much tasks are in fact performed by the computers now. They aren’t perfect, but they become better and better and the workload reduction is evident. In late generation combat aircraft a single crew member can act more efficient than ever before, but there are still tasks/missions where a second crew member is desirable.

    @Exec,
    the question is what is contained in these cost figures. Afaik Myanmar received used examples. It’s reasonable to assume that this cost figure includes more than the aircraft itself.
