    VERY reductive vision that could only show how biased the eval was biased..

    As a time saving measure in the future, I would suggest that you copy and paste this quote on your desktop. That way every time the F-35 is in a competition you can just paste. Don’t say I never helped you be more productive.

    Obviously a biased competition, that’s why they had independent agencies oversee the evaluation process… to ensure bias.

    thing is, if it’s simulated it is not tested but calculated… the whole purpose of test flights is to verify that calculations are correct. If you count on calculations to verify if calculations are correct, you’re just betting lives of future users of it that you’ll be lucky enough so as reality really matches your expectations…

    There are test points and there are test points. This was a sticking point between JPO and GAO previously. The F-35, by virtue of having three versions, had a massive amount of test points.

    JPO has wanted to eliminate superfluous points. We don’t know which testing they decided simulation would be sufficient to demonstrate, but you can be assured that those points aren’t at flight envelope extremes or asymmetric load manuvers. Furthermore, given the commonality between the three airframes, some test points completed on the “A” variant would be sufficient to validate corresponding test points on the “B” via simulator for example.

    Mismanagement… calendar event led development etc. Pityful. And of course block 4 will not be there in time…

    Only you Hallow, could spin that article to the negative. When di Briganti retires from Defense-Aerospace, you would be an admirable fill-in as a chicken little editor to “analyze” US defense projects.

    Do note that USAF F-35 procurement will be cut. Most probably this will happen by the way of reduced acquisition rate, this will drive the unit cost up.
    l.

    The program of record has not changed, the procurement schedule has been extended. Even with the reduced buy rate, the production ramp up coming in the 2020’s is more critical for driving down unit cost than overall numbers (which again, have not changed).

    Should speed up maintenance, no pesky access panel in the way.

    Nah, if you’re not interested in the actual lift force because you’re just taking it for granted that the aircraft can generate the required lift coefficient and has sufficient thrust to overcome the resulting drag, there’s no need to worry about bank angle. You’re doing it right – what’s so wonky about 26deg/s in that scenario?

    Yeah, sure. I assumed by the question he was looking at comparing corner speeds of different aircraft.

    @ Inst [/QUOTE]This roughly indicates that if the F-22 is G-limited at 9G, it can perform 28 degree / sec turns at up to 650 km/h, or mach .56 at 15000 ft [/QUOTE]

    It probably can but you need the E-M diagram to be sure of the aircraft envelope. BTW- you really don’t need to know the equations anymore, just go to one of the online pilot references that have turn rate calculators.

    your forgetting bank angle- the g’s generated depends on aircraft’s bank angle.

    Rate of turn= 1,091 x tan(bank angle)/ V(knots)

    What are they doing? well, flying gently in peaceful skies, I’d say… they don’t go nowhere near China or Korea with it

    Where are F-35’s deployed right now as part of a TSP deployment? Your prone to making generalizations that are flatly incorrect.

    10 F1 which in the context of the total planned fleet was 18% of all Rafales built for France. There are roughly 200 F-35’s that require various upgrades (some just the software load to 3F) to bring them up to full combat capability, that is roughly 17.5% of the currently planned F-35 procurement numbers.

    So, there’s that. Furthermore, the Rafale didn’t have the full range of weapons and sensor fusion until the F3 standard was introduced. I fail to see how the F-35 3i is somehow at prototype level yet a large portion of total Rafale production had to be upgraded to F3 to give full capabilities.

    F-35 will be ranked first on technical specifications, and it will be cheaper than either Rafale or Typhoon. The question remains; will be “sufficiently cheap”? Dassault tried to argue that a smaller nunber of Rafale could do the same work as the specified number of Gripen. LM can use the same argument, however with a smaller delta in costs it will be more likely they will succeed. Politics may stop F-35 of course (if it is perceived as “too agressive”). The SH could be a compromise between cost and technical requirements if politics prevents F-35 from winning.

    TBH- It very much depends on the RFI and how Swiss structure the competition. If they require a “fly-off” with Swiss pilots flying the competitors in a technical evaluation, that would work against the F-35. The Swiss aren’t going to qualify a pilot to fly the F-35 and there is no two seater (an issue Spud pointed out). The F-35’s flight simulator is highly realistic, but isn’t going to replicate a butt in the ejection seat. This is all speculation as L-M might offer the F-16V instead.

    Based on nothing but opinion, I’d say this is a European race. The US offerings will be very much the dark horse. Still give the Gripen E the best odds, and the Rafale having a reasonable chance.

    Which Eurofighter Consortium nation would be leading the sales pitch in a Swiss race? That might play a factor.

    @ Hallow:

    About cost, iwont bother answering, plaiin lie. Linked hdar hundreds of times the actual official costs of Rafale… WAY lower than actual F-35 cost (using SDD value for example). Not to talk about maintenance costs..

    Because you can quote the “actual official costs” of the Rafale via Senat docs all you want. The fact is, those numbers are vague. As I’ve pointed out before, you’ve claimed those cost represent Rafale F3 deliveries that year, yet the RBE2 deliveries didn’t even start until the end of that fiscal year. You constantly point out the “hidden costs” of the F-35, dispute the URF for the F-35 as inaccurate (despite having URF, total flyaway, APUC, PAUC costing made public every year). Yet with no cost breakdown, no itemization available for the Rafale, you assume those senat figures represent procurement cost.

    KGB- do find said post about MiG-35. Search my posts. You confused a response BIO had to another poster asking if that technology could be used on the Su-35S. I never responded because I couldn’t care less about your rants. But do look it up and then apologize because I said no such thing. You didn’t even know what you were looking at with that nozzle until I pointed it out. My only comment about that particular nozzle was after Berkut stated it wasn’t the type 30 engine, so it might be a prototype, not the definitive production nozzle. (And since then another nozzle claimed to be for the type 30 has been posted)

    Might it be better for all if we move on, already asked admin to delete this last page.

    Easy solution, ignore function.

    Believe me, the last thing I want is a reply from you. Go play with ur friends on “russiastronk” forum. There are posters who can engage in discussion without crying every time someone thinks a poster is bashing Russia. I’m not, but it does show your personal inferiority complex.

    Go run to the ignore function to save your delicate psyche. I’ll stay here and any other thread I please thank you.
    (Apologies to others on thread, I was responding to article posted by Austin. Certainly was not looking for our nationalistic friend to jump on response with such vitriolic fervor toward a different point of view)

    Didnt LM took the production line from Forth Worth to somewhere else?
    Found it, “Greenvile”, South Carolina.

    Yes, but the backlog of F-16’s to be delivered is zero I believe, so without a new order (and soon) that facility won’t be producing new F-16’s.

    be honest, even accounting for the significantly free-er nature of the press in the US, the coverage of Russia is anything but balanced in the US, even if we only stick to the question of Syria.

    – Broadly agree with what your saying.

    What I find worrisome is that this isn’t a reporter’s OpEd, or even a poorly sourced clickbait article. Viktor Bondarev is the former head of one of the major service branches and still the chairman of the Federation Council’s Defense and Security Committee.

    The usual unrelated kneejerk defensive tripe.
    This is the Russian Airforce thread.

    RussiaDefense called… they are missing you over there with the rest of the ignorant warmongers.

    Of course, you can stay and spew out your usual garbage like over the shipyard Carrier construction till I shut you up with the director of the Baltiysky Zavod saying in a publication exactly what I had said.
