    Problem with the sweep angle of the superhornet wings optimized for carrier operation rather than manoeuvres. The superhornet also does not provide the sensor suite the if has got used to on the Su 30 and MIG 29. The superhornet will not get to the kind of function that until the block Ii++. I posted a big essay on the family 18 deficiency by a think tank some months ago.

    Well India did the CAD work from the bottom up for the LCA so there is some knowledge base now.t”.

    Missed my point, being able to do some nice looking 3d work or mathematical calculations does not mean you automatically can manufacture a plane!

    I always had this feeling modern day fighters are over engineered to be jack of all trades and master of non. One plane to fight, bomb, interdict and strike.
    The MIG 25 was definitely not over engineered single aircraft for a very singular purpose. Going fast.

    My definition of over engineered is asking for a layer of something to have a strength, strain or fracture toughness value that is more than twice or thrice that which is required and then inspecting that material and rejecting it unless it is perfect.

    Another one that I think of is of picking materials that sound exotic even before the design is drawn so that you have a material that is costlier and stronger than it really needs to be.

    Third example is that during the research phase you decide to make everything automated or robotic but have not done a cost study that could tell you that manual application would be just as cost effective. One example of this is someone in a region where labour rates are low but yet spends money on automated manufacture or fabrication.

    Responding to a requirement of say 360 degree view with radar and other IR equipment, ability to carry XXXtons to XXXX Kms, XXX m take-off capability etc., will not be over-engineering, it will be responding to a requirement.

    Providing capabilities which were never asked for, or providing more than that which was asked for would be over engineering.

    Or making the aircraft structure overly safe as to impact on the aircrafts key performance characteristics or require a new/more powerfull.

    Does not really reveal anything new and or give any new information. Seems more like a lament rather than anything else.

    Just because they have not done the CAD work to make the shape of the aircraft it does not mean that there is not the 50-50 R&D in the aircraft. Just doing CATIA/FE models doesnt mean you can make a aircraft and nor does it teach you how to make one.

    The real learning is in actually making the structure and India will learn from this if it is clever enough.

    There is a risk mitigation action in how the project has been done.

    HAL and ADA can cut their teeth on the AMCA.

    couldnt they kill the F-35B and bring back the super tomcat?

    I didnt contiously mean it in that sense.

    However it needs to concentrate on existential threats from peer competitors and not be side tracked.

    Buy more F-22’s and cut down on F-35 VTOL, MV-22 etc…

    Does the US have something similar to Tanguska?

    I guess all that does make a difference… I would not be suprised about those types of things in the UK or Germany or Japan but was suprised that those porta-cabin barracks had pizzahuts and mcdonalds in afghanistan.

    No wonder people are still trying to develop autonomous cargo airships powered by solar panels.

    I was watching a BBC report once and i thought i had heard that some of the bases in afghanistan had Mcdonalds and pizza huts where the troops could buy food..

    :S I thought my mind was playing tricks on me but i am not sure now, wondering if they take saunas, gyms etc as well.

    They struggled due to poor command decisions. Peer competition would be pretty one sided at the moment

    Sorry lets change topic as I think we are creeping away from mil aviation.

    so getting back to aviation, if we cut the USMC numbers or the mv-22 and the vtol f-35 and the amphib tank we could have more F-22’s! more important now that we have evidence that China has a plane that could possibly be very similar to the PAK FA.

    The F-35 will not be able to compete with this plane. As the USNI have already mentioned when they went from the F-14 to the F/A – 18E/F they lost out significantly on capability (range, number of missiles etc etc)…

    Cut the F-35B.

    And abolish the US Army.

    What would you use to fight your peer competitors? Arguably since Vietnam the US has not faught an army that is its peers, it has saught smaller conflicts and sometimes still struggled.

    What about the Buccaneer? Would people say that the blown wing was over engineering?

    What does overengineered mean?

    Does it mean that bits and pieces are being added to an older airframe until it becomes a complete mess?

    Or does it mean that a plane is being designed on basis of very high and unrealistic requirements so that it needs unproven and experimental technologies leading to disaster?

    I would go for the second definition and then would point he finger at most recent developments from A400M to F-35.

    I wont comment on the A400M however I thought the F-35 was being realistic in some ways because although they put in the extra requirement for good avionics and stealth they always said that the F-35 will only be as agile or monouverable (? spelling) as the F-16.

    The vertical take off version is a different story, maybe for that kind of capability they should have just got the harrier on steriods.
