    The article actually says that “…the payload of fuel and weapons in STOBAR operations will be one-third less than the payload in CATOBAR operations. There will be no differences in β€˜bring-back’ capability going from CATOBAR and STOBAR.”

    oops my fault πŸ™‚

    lots of speculation in this thread and a form of protectiorism/mistrused

    I think this is only alternative if they skip F-35B or maybe F-35 alltogether and probably like in norway, only a way of pushing things in the JSF program.
    Who knows?
    SAAB is a luctrative company that used to pull big things with small means. With big knowlege of marine equipment.
    If this is going SAAB way, the work is needed to stay in britain for certain and a
    royalty for future orders, maybe even in NG orders?! This is probably a good case for britain. things Lockh. o Dassul.. will never do.

    Anyhow, i think its brave of SAAB pushing this. And certainly they dont think its to much modification at all, as many of you imply. And they probably know more of the buisnesscase than you guys after all πŸ™‚

    Also the cost of having gripen as a third fighter isnt as big as you might imagine. Especially compared to extended F-35 and EF fleets as alternative.

    ….but it also makes the ships, to get into that market in the first place, a good deal more expensive and inaccessible than ever before. Unless you believe that Sea Gripen will be able to STOBAR hop from a short deck carrier with any more than the ability to carry a matchbox the length of a football pitch!

    it has been given about 1/3 of the CATOBAR 16500kg max takeoff weight or about 3000kg of fuel and goods… give and take due to ship differences.

    I would take that as an ATA equipped raptor is more aerodynamic than most* any non-stealth jet with external stores….

    That is a myth..
    Internal stores was abandoned when speed was needed after WW2. The crosssection need to be small for low drag and to even cross the barrier.

    Now every “shape” stealth fighter compenate the drag with brute force and lots of fuel (fuelfraction) and thustvectoring in some cases.

    If i can foree the future, the future will probably skip the shaping and for more materials and coatings. Also go back to more slim shape and more compact weapons and storage. And and also more “stealth” external stores. And ofcourse more costeffective UCAVs

    Yes.
    Look at it this way:
    The lowest of all probabilities is when the antenna is passive,
    and the larger it is, the more it can absorb.
    “LPI” sends out a faint signal, and receive an even more faint signal,
    for that to be of use, the antenna need to be large,
    or the “LPI” ain’t so “LPI”

    LPI isnt a faint signal, its just hard to detect. example a TX very high energy short burst and frequency hopping.

    Viggen (JA37) had 88% of F-4 thust =125/(71*2)
    the PS-46/A vs. AN/APQ-72 was as i recall 85% 48/56

    by weight 12 200 kg(JA37) vs 13,757 kg (E version) is 89%

    both using skyflash but Viggen had a much better datalink and was conceved over a decade later.

    my replies in bold.

    i wonder when Tejas became NG comparible

    :confused: To date the NG hasn’t won any tender, it got downselected in Brazils now cancelled F-X2 competition and was invited to for others, but thus far Gripen NG failed.

    I count gripen as a platform not NG.

    Let me give you another suggestion.. Let Swedes kill the Gripen NG, and ask India for partnership in AMCA program. Because Sweden or no Sweden, Tejas and AMCA will happen

    IAF the evaluator thinks otherwise… Gripen has not been finalized as its too similar to Tejas.. dumb or otherwise

    as you said that even US of A has killed many its programs, and sure Swedes have no problems in feeding its own hungry people, so learning from the lesson, it should be a child’s play for it to kill and wrap up Gripen NG…

    noones going to kill the NG, Gripen E/F is going to be ordered at least by SweAF.
    And the jet has won halv of all itΒ΄s endevored tenders.
    So killing it is like killing its future and the good buisness with it. they maybe cut the developement pace, but never kill it.

    It was probably a Raptor.

    or a PAK-FA πŸ™‚

    oh
    NG (98kN) 9.8t – 8t =1.8t ??????

    Oh yeah, french data? :rolleyes:

    That, or your numbers are off.

    Nic

    as i said there probably >2100km.. which is kind of boring because we cant have the fun in calculate that! πŸ™

    Though I have done some calculations and arrived at the conclusion that a single ET adds 38% more fuel and reportedly offers 40% more range. This isn’t really viable as more weight and drag is certainly hurting your range. More fuel efficiency with more weight and drag isn’t viable and I suppose that the 1000 km figure is rounded anyway.

    it seems to me kind of reckless of Saab to claim this, if youre right, havent questioned it myself…
    Jet A1 density differs from 0,775 to 0,840. so its more likely to be 38%-41% more fuel. Therefore a round figure with linear asumption “40% more fuel gets you approx. 40% longer”. So maybe youre right. Something are wrong with the data. Hopefully we see some updated data soon in a new offer.

    The company should have the better data no doubt, but in this case it makes no sense. Except you want to tell us that the Gripen NG will have a range of 6500 km with 4 drop tanks, because that’s what the presentation suggests by claiming “One drop tank gives the Gripen NG an extra range of approximately 1000 km.

    well, its alot going on aerodynamicly when you add droptanks…so 6500 shouldnt be viable. 4075km probably is.
