    Ya, well don’t blame me for LM design choices. They did enlarge the F-35C wings, and frankly i can’t see other option. Krueger flaps and longer leading edge flaps was not enough, so they went for larger wing when Navy OP.

    That however does not translate into a larger wing gives bad cruising fuel consumption and sustained turn rate. The Flanker has allready proven that decades ago.

    Please stop, this is so muddled it is painful. First off, a larger wing would NOT give poor fuel consumption nor poor sustained turn performance, necessarily. Nor can you make a comparison of two different aircraft and proclaim that larger wings are better.

    The flanker’s wing area is as large as it needs to be to meet the performance criteria for which it was designed. You cannot proclaim that the flanker is superior due to a larger wing and translate that to the F-35. Increasing wing area of a particular airframe without changing other factors: overall drag, thrust, T/C ratio, etc, will have a negative impact on some aspects of performance. Increasing wing area WILL increase lift induced drag period… Get it through your head.

    It would be nice if you devoted so much attention to detail to each one of those 82 Israeli kills… I think good ~30 of them would be outright dismissed if the same logic was applied.
    My 0.02 only

    Keep your .02 cents. The reason why no one questions those 82ish claims is because the Syrians admitted to losing “upward of 60 aircraft” and the Soviets all but confirmed the Israeli claims:

    Usual suspects a work here….

    That the PakFa has much larger wing areal vs F-35 is totaly legit, I would flip it around and say if we could stretch the F-35 and put larger wings on it, then all for the better

    That is empirically false. In case you forgot, there IS an F-35 with larger wing area. The F-35C has the worst performance of the three. It may have better low speed turn performance and slower approach speeds at the cost of acceleration, overall agility. Adding bigger wings does not make a better fighter. It adds drag, and if thrust is not increased or overall drag decreased, you end up with inferior performance. Bottom line, simply adding larger wings to a particular design does not make it a better fighter- it has a cascade effect.

    Its simple logic. The F-35 makes up for its short lenght, and relative smaller wings by making the wings less sweeped, aka more SH wing style in order to generate the desired lift.

    There is zero logic here, wing sweep is dictated by wing shape, mission. The reasoning for the moderate wing sweep is twofold: subsonic cruise efficiency, and the type of wing.

    Anyway, you tried to argue that PakFa larger wings make it more draggy.. Which in this case, it don’t.

    compared to what? A Pak-fa with more wing area? Your right there is nothing like lift induced drag, huh. I suppose that’s why L/D ratio isn’t important.

    They did score 82-0 in their claims only.. I think it’s time to let these claims undergo the same critical judgement as claims from Syrians or Iraqis, where people are demanding proofs, videos, wreckage pics, loss confirmation from Israeli MoD, birth certificate of the pilot andwhatnot.. How many wreckage pics of Syrian MiGs can we find, BTW?

    Which would be logical……except that the Syrians themselves admitted to losing “at least 60” and Soviets later looked into the battle and comfirmed Syrian losses. The only difference is that the Syrians claimed something like 12-17 kills (Soviets claimed Israel lost 70 aircraft).

    Iraqi losses in D.S. are well documented. Considering U.S. had awacs coverage, debriefing, wingman confirmation, and most importantly a clear picture of exactly what was happening (unlike the Iraqis), yes I would take U.S. claimed numbers over Iraq. Hell, they were still trying to sort which aircraft ended up in Iran.

    You know how weapons trials is done? Its not just about separation test. There is also the software from weapons suite to deal with. Also Asymmetrical loading etc etc. The list is long.
    Much to do before the weapons are launched from bays.
    Anyway. Yes Aktubinsk is a black hole and so is Sukhoi these days.

    yeah thanks, very aware of how weapons testing is done. That is why the question remains. We have seen the Pak-fa with external weapons for over a year now. I don’t think that a press release that pit testing or separation tests of the internal weapons bay is top secret. What it tell me is that there is still a considerable amount of flight testing remaining. The list is long, and we’ve seen the Pak-fa with AtG and various AtA loads on external pylons. Sugarcoating this by saying somehow these test are being conducted “in the black” is not going to fly. There has been a steady stream of information about flight testing, there is a obvious hole: no pics with internal bays open, no press releases, this is fact.

    5; There are pictures of them open with missiles (mock up) inside.

    I’ve seen the patent drawing, I’ve seen the hinges, 100% agree. But, the only picture I’ve seen of the open sidebay with a missile in it looked remarkably like it was a photoshop job. Do you have said pictures with the mockup?

    Look, actually US/west is taking a lot from the WP experience. And vice versa.
    Think about IRST/high boresight IR missile or F-35’s ALIS itself .
    Sweden/finland practises also have put a lot of useful teaching.

    Again with this! The US had IRST systems in the 1950’s. They stopped using them due to radar improvements. The U.S.S.R used the systems the same way originally: as a way to aid radar lock on. Yes, the development of the OLS-29/27 was a step forward in IRST technology.

    Which brings us to High off-boresight aam and HMS. As they say “success has many fathers”, so too does technological advances. The U.S. trialed the high off-borsight missile in the early 70’s as well as the HMS.
    http://www.designation-systems.net/dusrm/m-95.html
    USAF had the Aim-82 (cancelled and merged with aim-95)

    Aceval/Aimval led to the simulation and trialing of high off-boresight aam’s and the HMS. The results led to the cancellation of the Aim-95, they found that in “many v. many” fights, even the HOBS missiles and HMS did not significantly improve win/loss rate. So, the USAF pushed for the development of the AMRAAM to extend engagement ranges and avoid the merge. ACEVAL/AIMVAL showed that even having the more powerful and maneuverable fighter was not a guarantee of an acceptable kill ratio- even a 2-1 win/loss rate would have been failure for the F-15 which could not be procured in numbers approaching the Soviet inventory. The Soviets went the other way and fielded these systems, giving them an advantage in the merge, just as the AMRAAM would have given the F-15 an advantage in intermediate range engagements. Different doctrines. Thankfully we never had to find out who’s was correct.

    BTW, exactly how is the F-35’s ALIS related to anything coming out of the Warsaw pact or anywhere?

    Anyone still in the theory that canoes are for Short range missiles ?

    Don’t think it’s a theory. Pretty much confirmed. Not suprising to see them mounted on external pylons, we’ve yet to see ANY pictures of the internal bays open or any weapon testing with internal weapon deployment reported. It seems there should have been some information on separation tests or static tests with bay doors open.

    It is a great pity that Czech pilots were not informed about MiG-23’s “horrible, horrible handling”. They even went as far as performing at airshows!
    https://www.youtube.com/watch?v=1ZpvnRib6jY

    What do airshow performances a have to do with the fact that the Mig-23 had unfavorable handling characteristics. Why do you think the ML and the MLD had extensive changes to airframe, FCS? Could it be because the early models exhibited exactly what I stated: high speed directional instability, spin prone and dangerous in hard maneuvering?

    The MLD was by all accounts a major improvement. But by ’82 ’83, the Mig-29 was replacing the -23 in frontal aviation regiments.

    His post is gobbledygook, but I don’t see how it is anti-semitic.

    Criticizing Israel or Israel’s policies is fair game.

    It is his ridiculous word salad, counterfactual posts that I find offensive.

    Fair enough, I start reading “Zionist” comments and tying it in to Warsaw ghetto comments and it reads like a holocaust history revisionist. That, on top of the raving, rambling posts and I found it to be unacceptable.

    Eagle,

    [
    Ask anyone, I despise Israel. The United States is not the mule of that nation’s genocidal plan to reconstitute a biblical state by slow-slaughering the Palestinians in a Warsaw Ghetto like environment using 3 billion dollars per year of our FMS as IG Farbening equivalent war crime trial funding.

    We gave real blood in WWII, to the tune of 400,000 lives to help Israel exist.

    That is enough.

    Especially as the ‘Israelis’ gave us Hart Cellar in return while demanding an _ethno state_ of their own. We could be helping the working poor into housing with 12,000 X 250,000 dollar home mortgage payoffs EVERY YEAR with that kind of money, better spent at home. We owe them nothing. And so I am no friend to the Zionist cause.

    But.

    You can count on the Israelis to give a no-shine opinion on anything military. They know they cannot afford to be playing wishful-thinking games with brochure figures against the overwhelming numbers of very hostile threats surrounding them on all sides.

    Thus the Israelis humiliated Grumman when they tried to sell them on the F-14, trouncing it repeatedly with A-4 Ahits in one on one and one vs. many DACM fights which made ‘Top Gun’ look like an adolescent slumber party pillow fight.

    And so it is, that while IAI/IMI literally, physically, cannot integrate most of their own weapons systems (Spice, Pythons, Delilah, Popeye, Derby etc.) into the F-35’s small weapons bays and _knowing_ how poor a maneuvering platform it already is at present loaded states, what do they want to integrate, first, as external stores? EFTs and CFTs that’s what.

    And now you start to understand why the USAF chose to show up at the EAA with a warplane that has no business being there given the test and modification schedule needed for IOC and then lied about ‘how great a set of legs it has’.

    http://ichef.bbci.co.uk/news/660/cpsprodpb/9BE2/production/_84260993_iran_nuclear_624.gif

    Because the same distance from Eglin to Oshkosh can be overlaid as a radial on a map connecting Tehran, Arak, Fordo, Isfahan and Bushehr as the primary Iranian nuclear facilities with Ramat David or Hatzor in central Israel. These are the shortest routes but not the ones most likely to have success, especially if it’s a glorified tanker drag. The best choice then, especially with heavy weapons able to penetrate 8-23m roof thicknesses like those of the central production hall at Natanz, lies on a circuitous routing trhough Turkish airspace and down from Orumiyeh fully another 400nm over-fence to central Iran. Total RADIAL, one way, distance thus being something like 1,206nm.

    Of course, with Erdogan off the reservation, this is all subject to change. But in any case, it is ludicrous to assume that you can fly tankers over Arab states which you need STEALTH to transit with a fighter as surprise initiative and DCA avoidance. Not once. But for multiple dozens of sorties. Because you have to use heavyweight penetrators just to seal the bunker doors.

    This is the kind of interpolative research you have to do before you take the USAFs greed-is-good word for _anything whatsoever_. Because they have not been our nation’s defenders in decades. But they will shine-on the F-35 to Israel, just to have the latter’s ‘real warfighters!’ sung praise acceptance of the Adir.

    Reported- go back to the tin hat anti-Semitic place from whence you came. Your posts are gibberish and offensive, not to mention the worst type of regurgitation of refuted garbage this forum can do without

    Calculation. For the fourth-generation aircraft range is obtained less real

    Paralay, you are using fantasy numbers vs. the observed performance of the F-35 on combat radius- the ferry range is not less than the 2x the combat radius how are you not getting this? How exactly do you figure your estimate are more accurate than the OBSERVED and reported figures? This is two pages of made up fantasy, just quit.

    It would be a great counter to F-4E AIM-7M combination; 4x similarly ranged BVR missiles, arguably better radar, better maneuverability and far better acceleration on a smaller airframe.
    Because again, it faced much more modern adversaries.

    What model of Mig-23 are you referring to? The -23 had horrible, horrible handling characteristics until the MLD. It had fantastic acceleration and…. that was about it. poor visibility, poor radar, instability, prone to spins, the list is endless.

    You can’t base an argument on “war isn’t fair” and chose a specific time to make such comparsion; a time that would support your claims. Lets talk about 1990 then? A time when;

    -All Su-27/30s were flying with R-27RE/TE + R-73s, but F-15A/Cs were still flying with AIM-7M+AIM-9Ms.
    -All MiG-29s were flying with R-27R/T and R-73s, some even had internal ECM whereas F-16s had pathetic radar and they were even lacking BVR capability altogether, solely capable of using AIM-9M.
    -MiG-31 had Zaslon, only PESA fighter radar back then, againist ageing F-14s with its AWG-9, and it was faster and longer ranged (supersonic) then its contemporary.
    -Majority of MiG-23s were upgraded to ML/MLD levels, with true look-down shoot down radar and better R-24 missiles.

    In fact, apart from legacy F-4E and Tornadoes with AIM-7s and Mirages with Super 530s, no airforce in Europe had fighters with BVR capability.

    If all hell broke lose back in that day, it would be an easy “walk over” by Soviet airforce againist NATO.

    This is a highly questionable argument. The Su-27 wasn’t even fully operational, and had issues with radar throughout the early years of deployment. The -29 nominally had BVR capability, every single pilot who has ever flown the early Mig-29 from western air forces made the same comments: you could fly or you could fight with the Mig-29. The MMI made it very hard to do both at the same time, and the heads down scope made BVR shots a pleasant fantasy. I’m not saying that NATO would have won, in the air I think it would have been somewhat of a draw due to Warpac numerical superiority. There is NO doubt that NATO had a vastly more effective system in the E-3 Sentry over GCI and overwhelming advantage in AAR which was a significant force multiplier. How many sorties would frontal aviation equipped with Mig-29’s have been able to mount with the aircraft returning to base to refuel every 1-1 1/2 hours. I think that you and JSR might agree on this, no one, not even Soviet era officers would agree that the air war over AFCENT would have been a “walk over”. 12 squadrons of F-15C would have made it a bloodbath on both sides.

    Addition- RAF was still flying FGR.2’s in 1990 as well as F.3 Phantoms. The 33rd TFW was already equipped with Amraam by 1990, and had been evaluating them since 1988. (official service entry was 1991, but 33rd TFW was using them already).

    Can you give us the source for this assessment? kinda the first time i heard that tapered trapezoid have lower transonic drag than delta, it sound like a made up theory to me

    Actually this is partially true, trapezoidal wings are low aspect ratio and assuming low t/c ratio have low supersonic drag. Delta wings with canards (like Rafale) tend to have very low drag in the transonic- not so without canards.

    Leg fails to mention that the F-35 wings are classified as trapezoidal. And I don’t think the F-15’s wings qualify.

    For the love of God, stop posting the graphic from the 2012 Norway briefing. It is so old the 728nmi radius includes 2 EFT which are not currently planned.
    https://norway.usembassy.gov/root/pdfs/volume-1—executive-summary—part-1_dista.pdf

    Spuds 2016 L-M graphic on F-35 air to air combat radius and the 625 nmi on the USAF mission profile reported to congress suffice to give an accurate picture of the F-35’s radius on different mission profiles.
