    1. The new RBS-15 will be much lighter (and presumably also smaller) than the current RBS-15.

    Same dimensions

    Very interesting this comment, since that Gripen E/F should be much better in all aspects because its has been increasing the size as well as the weights in relation at the Gripen C/D, however the new version of the missile RBS-15F should be better because it will be lighter and smaller than its current version…

    Perhaps my brain needs at least another million years of evolution to understand this concept of alternative realities,

    While the E is bigger and heavier, it also has more thrust and a lot more fuel than the C… The Gripen E by comparison with the C maintained its thrust/weight ratio while having a much better fuel fraction. On top of that if the external cargo carried by the E is lighter than what the C would carry, its entirely normal that it behaves better.

    I know this is a massive ‘what if’ but if British Aerospace had won the contract for the JSF with the Harrier GR11 what would the aircraft look like?

    By “contract for the JSF” you mean British Aerospace being the prime contractor and winning the Pentagon competition for the USAF/US Navy/Marine Corps replacement for 7/10 of the entire american tatical fast jet fleet?
    Thats not a massive “what if”, thats pretty much impossible.

    The GR7/9 have many general design similarities with the GR1/3 but are clearly much more advanced designs, how would 21st century engineering, aerodynamics and avionics have been incorporated in to the Harrier GR11?

    You could throw every ” 21st century engineering, aerodynamics and avionics ” into the Harrier airframe that it still wouldnt be capable of cover one single KPP for the JSF program except “getting airborne”. 😀

    If your question is “what would a new ASTVOL BAE design after the Harrier look like”, well, like this:

    If your measuring stick is the F-35 then of course the SH falls short.

    If you compare the SH to the Eurocanards, in terms of RCS reductions my guess is it’s the same ballpark. The ASH suggested by Boeing also demonstrates a significant growth potential (which of course pales in comparison to the growth potential of the F-35).

    Cost wise it seems to be cheaper than both Rafale and Typhoon… I am not sure how it compares to F-35, Boeing seems to be challenging the conclusions made in Denmark.

    I saw a Belgian poster suggesting that Belgium should go for a mix of SH and Growlers, arguing that operating costs of F-35 is still a bit of an unknown, and that Europe will in any case have a significant number of F-35 whereas Europe has very limited stand-off EWS capabilities.

    He actually does have a good point… Even tiny Australia has infinitely larger numbers of Growlers than Europe (which currently has 0). And for Europe (or NATO) whether Belgium adds 34 F-35 or not does not really make a huge difference in the grand scheme of things.

    Both France and Sweden probably has the know-how to develop a Growler version of either Rafale or Gripen but it has not yet happened.

    I am going to make a prediction, for the foreseable future (lets say a decade) every European Country West of Ukraine, that is going to acquire new combat jets are going to a) order “Dave”, b) order a variation of Gripen and c) order some Vipers from AMARC, the main KPP being “size of budget”. The two exceptions will be France with the Rafale F4 and maybe Germany with the Tornado ECR replacement wich could go “Dave”, upgrade sensors/weapons for their Phoons, rebuild the Tornados and use them for the next fifteen/twenty years, a mix of the two/three options, or nothing at all.

    !!!

    Well thanks! Its not every day that i see a design that i am entirely unaware.

    That design is so… different!

    meaning the F-35 is going to need a crapload of upgrades to remain relevant, or have to compete with aircraft that cost a fraction of its price for equal performance

    Name one of those “aircraft that cost a fraction of its price for equal performance” please?

    No. What is official is that there will be engine evolutions for F4. What is known is that present air intakes limit engine power to 8.2/8.3 T (limit of air flow). It is also known that a 9T derivative of M88 was tested several years ago. That a higher thrust would be a nice goodie for STOBAR carrier operations. t is known that very hight temp derivative of M88 hot core is being tested (albeit for FCAS atm).
    All in all , it is probable, but definitely not sure, that there will be a 8+T version for F4. Thats what is said in the article.

    Thanks

    yes from 75kN (~7.6t) to 8.2t (~80.5kN)

    Is that official?

    lol, by the time we get those F-35s flying they’ll be obsolete, and handed their asses by unmanned outdated Migs

    and people ask me why I avoid paying taxes in Belgium

    There´s absolutely no public information about a Russian (?) program for “unmanned outdated Migs”…
    Actually the only funded program for transforming 4ºth generation fighter jets into unmanned “thingy´s” is for flying targets.

    I am afraid you are already being proven wrong by SAAB, Raytheon and Northrop Grumman that have offered or have considered offering “large airborne GaN Antennas” for programs of record.

    Not only offered but already contracted. The two new UAE AEW´s will field a GAN Erieye radar.

    But this analysis (at the OSD) isn’t about pitting a 2017 F-35C with a 2016 F-18E but about pitting something ordered in the 2019 or beyond budget years for deliveries into the early to mid 2020s. Essentially once you have some of the changes Boeing would require to compete with the F-35C you are probably looking at a good 20-25% increase in cost (software, engine upgrades, CFTs, pods, RAM treatment, radar upgrades etc etc) That gets us to a $90-95 Million Super Hornet (2020 orders) vs something like a $115 Million F-35C.
    .

    I wasnt discussing an upgraded F/A-18E/F versus an F-35C, or any analysis.

    Someone wrote and i quote:

    I doubt if a normal F/A-18E is any cheaper than the F-35C to buy or to keep flying.

    I simply pointed that was not true and it wont be.

    And yet from the same document:

    2017: $166,829.500 each for 4 total planes
    2018: $134,769.000 each for 6 total planes
    2019: $124,382.000 each for 12 total planes
    2020: $116,522.833 each for 18 total planes

    So the cost for FY2017 is artificially high only because of the low number of planes being ordered that year. In fact for FY2016 it was at $132,829,500 each for 6 total planes. As opposed to the Super Hornets and Growlers, where Boeing is building 2 or more per month (i.e. 24 or more per year) since they’ve said that’s the minimum for it to be economically viable.

    And?
    Off course that the costs of Dave C are high because the numbers being built are low, are we ever going to see that particular aircraft costing the same has a SH in the same exact year? According to the US Navy Budget, the answer is a “NO”. The SH production lots are going to dwindle before the US Navy starts to acquire Dave C in numbers.

    It had better be given that that Gripen couldn’t likely fly much past the airfield fence in that loadout.

    🙂

    The Swedish chaps have thought of that, the Flygvapnet air Base at Lulea is right besides the Baltic sea.

    First time I have noted this.. is the IRST ball off the axis of the aircraft?

    Yes
