    Seems accurate except the Raptor top speed.

    Accurate number would be 2.4mach.

    Also, those AMCA numbers are very ambitious.

    Uninstalled thrust target for AMCA is 180KN- two Safranised Kaveris will be able to deliver that.

    Other than that, if ADA can produce the AMCA to these specs it will be a very very decent machine.

    + the T/O run is weird, the AMCA would need 2-3 times the distance as all other fighters on this chart? That can't be right.....

    Yeah the FGFA will have >200 KN thrust.
    F-15 is a beast! That would be quite the accomplishment.

    Not all of those numbers are correct. The F-22's MTOW is obviously wrong. AMCA's should be more or less correct, but it must be for the demonstrator, not the production version because the thrust rating is too low.

    It looks very unprofessional considering the large number of incorrect values for all jets.

    @MilSpec Check the fuel load for AMCA. It's 6.5T.

    It has one of the highest internal fuel capacities but one of the lowest ferry ranges....

    Don't go by those figures, they are all mostly wrong.

    Its probably created by some fanboy or the BCA graduate scientist from DRDO/ada to save their @$$es.

    Apart from some wind-tunnel model, simulator & serpentine intake nothing much has been developed on AMCA front, the guys at ADA have learnt few techniques from DRDO on how to make ppts & posters to keep the forum guys in discussion mode.

    Besides the MOD Babus and the Defence forces, is there not anyone outside of DRDO whom they are answerable and accountable to on their deliverables?

    i disagree , there are many PSU's doing great . EIL , BEL , all the metro rail projects specially DMRC are few examples , maruti is another example sir . the problem is top management but employees . people are same in every PSU's , talent is world class but problem lies in the top management .

    Since the chart doesn't show any official signatures, we can assume that this is just based on PKS and as I often said, his access to official infos is great, but his conclusions are bad!

    In this case it's starts with the problem that he "tries" to compare the performance of 4th and 5th gen fighters, but calculates the TWR without mentioning the empty weight?

    He also only added the internal fuel, which is ok for a 4th gen fighter comparison, but has a totally different meaning for 5th gen fighters, since the latter is designed to operated mainly on internal fuel, the earlier isn't. So if you want to know the performance on an equal basis, you need comparable internal and external fuel, as well as load figures.

    Which then leads us to the maximum external load, which again has a different meaning for 4th and 5th gen fighters, since the latter only should use external loads in low risk missions, while it is designed and developed for internal carriage.

    Also interesting, he shows the wing area, but doesn't calculate the wingloading.

    So even before you look at the accuracy of the individual specs, you know that the aim of the chart is flawed and basically has no meaning.

    Yes this is from his site but i don't think this is made by him. Probably some poster (notice the reflection.). And the file name says 'cemilac'. so..

    Most numbers are wrong but we get an idea about AMCA specs. I'm disappointed with MTOW, why build another near heavy fighter when you are going to order FGFA. Should have sticked to the rafale/EF class.

    Didn't noticed that, but since he usually mark official sources, I'm not sure. Anyway, if he posts it on his site, he needs to answer to the flaws too.

    With my rationale would have guessed similar to that of F/A18 E/F Super Hornet. Same Engine :hula
