    F16A vs FA18C/D + E/F at the same altitude with the same speeds is apples vs oranges?

    it is when the loadout isn’t the same

    and it’s especially funny when you have no idea what loadout the guy is talking about when comparing to the Hornet in the first place.

    Comparing unknowns to unknowns, yeah, that’s useful . . .

    That might be the case, it also has a lot to do with altitudes.

    This is what I compiled it from.
    F16A @15K with sidewinders http://www.f-16.net/attachments/f16a-15k.jpg
    F15 (what version and altitude?) http://lockon.co.uk/img/technology/pic1_9.jpg
    FA18 C/D + E/F @15k: http://www.f-16.net/attachments/f18_turn_rate1_576.png

    F16A and FA18 both at 15K, the altitude of F15 is not known.
    The chart @15k for the F16A matches this one: http://www.f-16.net/attachments/f16-sust_680.jpg (not fully at lower speeds but in general its not very far from it)

    wow, so now the truth is revealed

    your ‘data’ is compiled from a variety of different sources making very different assumptions.

    you’re comparing apples to oranges to kumquats

    in other words, YOUR CHART IS WORTHLESS lol

    You do know what instantaneous turn rate is, right?

    Except the quote isn’t talking about instantaneous turn rates, so what are YOU talking about?

    Do you see this? The F35C with the best turning capability has a cap for instantaneous turns that is the yellow dotted line.

    Would you please refrain from making up stuff that you obviously have no clue about?

    Still congruent with both sources.

    only if you stetch and twist and strain his plain meaning to fit your preconceived notions

    Sorry, my quote directly contradicts yours and you have no basis to assume yours is the correct one.

    Thanks for the update though. Now I have 3 sources that say the same thing.

    LOLOLOL

    The most detailed comparisons reach those conclusions.

    http://www.livescience.com/3032-fighter-jet-controversial-future-fleet.html

    Turning at the higher Gs and higher speed portions of the flight envelope, the F-35 will “almost exactly match a clean Block 50 F-16 and comes very close to the Raptor”, Beesley said.

    I think I found one

    Think again

    I think you are wrong, unless of course you are a pilot that has experience from both the F35B and FA18.

    Selective quoting at it’s best.

    Plenty of pilots say it’s very similar to a clean F-16

    Why don’t you use those quotes? That’s right, it doesn’t fit your agenda.

    @irtusk Give me something new if thats the case.

    They haven’t been released afaik

    And that’s where F35B/C will fit.

    no

    Please, try to understand that the F35 is not designed for dogfights.

    Please try to understand. You’re wrong.

    At the same time the FA18C and E are lagging in the turn performance. Thats where the F35B and C are when it comes to dogfighting performance. The F35A is slightly better and will stay under the F16As performance.

    If you believe that I have some lovely land in Florida to sell you . . .

    Also hilarious that you’re using such obsolete data for your comparison.

    No. Just as the Higher Mach figures of other jets like F-15 are very hard and rare to achieve, it will also be that way for F-35

    No, there is a fundamental difference

    The limits of the other jets were aerodynamic and thrust limits, meaning they were very hard to achieve except in special circumstances

    The F-35s limits are structural limits, meaning it’s ‘easy’ (relatively speaking) to achieve but dangerous to exceed.

    it is not excluded from the laws of Aerodynamic and physics you know..

    What laws of aerodynamics and physics prohibit the F-35 from reaching M1.6?

    Not matched by the F15 you mean?

    yes

    Still, thats what its capable of.

    false, no F-15 flying today can reach M2.5

    Just like the mach 1,65 is a white elephant for the F35.

    false, most if not all the F-35s currently flying can reach M1.6

    It is important to understand where the M1.6 limit comes from. It is NOT power-limited, it is limited by the aerodynamic heating of the various components of the plane. The F-35 has no problem reaching M1.6, they just dare not take it faster or they might suffer serious damage.

    In fact they did suffer damage from aerodynamic heating on the first flight to go past M1.0 so that component had to be redesigned.

    Nice speculations, the F15SE however is having very similar specs to the Strike Eagle.

    So you think Boeing can add conformal weapons bays and fuel tanks plus stealth treatments with zero aerodynamic or weight penalty?

    What are they made out of? Magic pixie dust?

    Are you serious about comparing the F35 to the F15 in WVR, speed and handling? Did you see the chart i posted and did you see what your own source said? The F15, as I and your sources said, is faster and more agile than the F35.

    And as I said, that chart is obsolete. It is based off the original clean F-15A which has no relationship to the performance of today’s heavily loaded F-15E and even more heavily loaded Stealth Eagle

    Well, if you are comparing a fully loaded F16 to a clean F35 then of course the F35 should have better handling, speed, climb etc.

    No, comparing a combat-loaded F-16 with a combat-loaded F-35

    Don’t forget the fighters always drop EFTs when they go to WVR :).

    a. not if they want to make it back home
    b. not the conformal ones the SE variant would use

    In the real world, F-35 also get laden down when carrying ammo,
    so its a moot point.

    No, that’s what they were saying, an F-35 with a full internal load of fuel and ammo performs similarly to a clean F-16

    At speeds around M1 and high alt., drag from 4 amraams will at most make 1% difference

    Don’t forget the external fuel tanks they always fly with

    Boeing http://www.boeing.com/news/frontiers/archive/2009/july/i_ids01.pdf:

    I read what Dozer (the F-22 pilot) wrote about the F-15’s actual performance before he went back and scrubbed it all

    M2.5 was done by the specially stripped-down ‘Streak Eagle’ flying a special profile to set a record that has never been matched since.

    Dozer personally flew an F-15 to M2.0 exactly once and it took over 15 minutes to get there. (This was in relation to how easy it was to hit M2.0 in a Raptor)

    Any theoretical Stealth Eagle variant is going to be even more heavily loaded down and less aerodynamic, so good luck getting even that fast.

    The F-16 is also theoretically a M2.0 aircraft, but there are plenty of reports about how an F-16 requires afterburner to keep up with a non-afterburning F-35.

    Whatever theoretical top-end speed these planes can reach in special circumstances, the F-35 has more USEFUL speed.

    This is what a pilot says http://www.defensenews.com/article/20110516/DEFSECT01/105160302/F-35-Tests-Proceed-Revealing-F-A-18-Like-Performance

    And there’s plenty of other quotes that say it matches a clean F-16.

    But the main point is real world maneuverability (that is what we care about, right? The real-world?) and neither the F-15 nor the F-16 will ever fight clean. So their theoretical clean performance is irrelevant.

    F15SE gives great range, versatility, agility + speed that the F35 can’t keep up with (mach 2,5 vs mach 1,6).

    The F-15SE can’t go Mach 2 much less Mach 2.5

    Plus it is in no way more agile than the F-35.

    Russia Denies Losing Indian Arms Tenders

    Russia’s state arms exporter Rosoboronexport denied on Wednesday media reports that it had lost tenders on the delivery of heavy-lift helicopters and aerial tankers to the Indian air force.

    “Rosoboronexport denies media speculation about Russia’s loss in both tenders as these reports are false,” the company said in a statement.

    “The results of these tenders have not been announced, and any premature speculation on the subject misleads the public and professionals, both in Russia and in India,” the statement said.

    Media reports in Russian and Indian media earlier indicated that the Russian upgraded Mi-26T2 Halo heavy-lift helicopter lost to the Boeing Chinook CH-47F, while the Il-78MK-90 aerial tanker lost to Airbus A330 MRTT.

    The C-5M might be able to fly from CONUS to the Stans non-stop but she can’t come back on the same tank. Such direct-to-objective missions are pure peace-time stunts.

    http://www.af.mil/news/story.asp?id=123297606

    Dow, who’s been a C-5 maintainer for more than 10 years, was among 14 aircrew members who took a C-5M on the Air Force’s first direct delivery airlift mission through the Arctic Circle from the United States to Afghanistan in 2011. On the 14-hour-plus flight to Afghanistan, the C-5M carried cargo for the Operation Enduring Freedom mission and “proved a strategic direct delivery concept.”

    On its way back, the same C-5M was also refilled with cargo from Kyrgyzstan, Southwest Asia and Western Europe that needed to be returned to the U.S. — making efficient use of nearly all the 270,000 pounds of cargo capacity in the plane.
