    Which years report was that please.

    It’s not about opinions you need to check your facts more before posting – otherwise you are not really helping yourself!!

    Thanks don’t need ur fact checking I know what I’m talking about. Google is ur friend.

    Exactly what facts have u presented to refute AFM and the DOT&E, other than confusing a threshold with objective? BTW, aren’t you the same poster that tried to argue with me that there was no record of the F-35’s 370 kt 9g turn rate at 15,000ft till I shut you up with the article. If fact checking is your goal here, your off to a checkered start.

    Needless to say if you have a threshold requirement of 60% fuel then making it 100% fuel without the USAF wanting that -)

    Well, I guess if AFM saying it twice isn’t enough then you could read the DOT&E report that states that F-35A are restricted to 3g’s with a full fuel load rather than then planned 7g in 2B configuration, and that the planned fix will allow full 9g envelope with 3F. But I guess opinions trump official reports and Air Force magazIne here on a forum.

    just add a pinch of pixie dust and its no stretch F-35 goes where no fighter has gone before

    What an insightful post, please elaborate as we all know your exquisitely knowledgeable.

    The Bowman paper from 2008 clearly specifies a USAF threshold requirement for 9G at 60% fuel and no A-G Ordnance remaining – which not only seems more logical but looks relatively similar to other aircraft – guess time will tell.

    Threshold being the key word to what you posted,not objective. The AF magazine article does not mince words. Gotta read the sources.

    Two quotes from AFM article I posted, “the Air Force F-35 variant, fully loaded for combat, can pull nine-G turns with a full load of fuel and missiles”
    And:
    “it was designed to maneuver to the edge of its envelope with a full internal combat load”

    So Lets be clear. Can the F-35A do(certified) 9G with full fuel tanks? Thats over 8000kg of fuel..
    Energo at F-16.net posted a chart from Norwegian MoD years ago showing it was confined to 4,6-5,5G. But that was probably with different Block versions..
    .

    I posted the link above, read it for yourself. Both -22 and -35 are rated for 9g with full fuel and aams. Requirement for LO fighters to be built strongly to carry internal weapons.

    Of all requirements making no sense at all, this beat everything IMHO…
    How is possible that a plane in a normal combat environment has still full fuel after it has dropped its own payload :confused:
    It can be possible just in case it make aereo refuel in the way back home but in this case it would be in a quite safe position in itself.

    Your confused. Basically, taking off on an air to air mission with just missiles and fuel, the F-35A is 9g capable (just like most other fighters), the difference being that the F-35 carries a hell of a lot more fuel. Conversely, on an attack mission, the aircraft is g limited (like other DFCS, the g demand system will limit pitch, roll, etc. based on load), until free of bombs.

    Back to the F-35 quite a lot of people here insist that the F-35A is/will be cleared for 9 g with full internal fuel. Is there any factual evidence available, possibly in the shape of a gross weight clearance? ?

    Nothing like a gross weight clearance or specifics of the envelope have been released (other than corner speed for 240-3)

    The first mention of the 9g maneuvering requirement with full fuel once air to ground weapons expended is in the oft mentioned Bowman paper.
    Second is from http://www.airforcemag.com/magazinearchive/pages/2012/november%202012/1112fighter.aspx
    There are other documents but these two come to mind.

    The statement by which datas published in 2009 were superseded by datas published in 2010 is accurate. What happens since then doesn’t make it inaccurate, and that’s were your logic is flawed.
    Now I’m growing tired of being lectured by a bunch of fools.

    Wait, why exactly are the people pointing out that your assumption was wrong, which led to you getting testy, fools?
    There is only one fool here, the one that just can’t say “Oops, I didn’t look at the recent numbers to see they fit the 2009 study”.
    Were you not trying to discredit the numbers? What were those numbers again for the representative CAP combat radius? 2009: 759nmi 2016: 760nmi, hmmm.

    The foolish act is to get defensive and lash out at everyone. Move on then…..

    I know, but that doesn’t make it. So what ?

    No offense, but you jumped into a debate with an inaccurate statement. You wanted to say that the L-M document was outdated because the F-35’s range estimates were reduced. In truth, the range estimates have increases slightly since 2009 based on two things-
    1. The testing has yielded

    (the change was data maturation from recent flight test data which resulted in a lowering of the fuel flow factor margin from a ~5% to a 4% margin. Lower fuel burn means greater range)

    http://www.dod.mil/pubs/foi/Reading_Room/Selected_Acquisition_Reports/15-F-0540_F-35_SAR_Dec_2014.PDF
    2. Easing the USAF mission profile to allow the F-35 to fly at optimal alt/cruise at the very beginning and end of the scenario.
    These are still based on end of life engine performance, and include the 5% fuel reserve required.

    So… What? I suppose you should not be surprised if people correct you on a forum if your wrong.

    Surface combatants yes, but what about cargo ships or tankers? Have they build anything larger? For example, South Korea never built a large warship, but they do build 500k ton 380m long TI-class tankers, they have also built Barzan (200k ton 400m long cargo ship) in ~6 months. No one can say they will have problems building a 100k 330m aircraft carrier. Could same thing be said for Russian shipbuilding industry?

    Admiralty yard has built some large ships. However, a 300m 80,000 to 100,000 ton carrier? commercial ships are in GT, or deadweight tons for cargo ships and tankers.

    From what I recall last time talk of a new carrier came up, there was no drydock large enough to accommodate such a ship. No recent experience building a large naval ship in blocks like the QE class, new propulsion, berthing, maintenance facilities to support such a ship.

    -sorry we took this one far off topic.

    I missed nothing, I just don’t care much. But the fact that you took an outdated source to make a point reinforces my feeling that you don’t deserve much attention.

    I think your the one with dated information. The 2015 SAR made it clear that fuel burn was less than estimated and the range has improved from 2009. Btw, the specs were based on the eariler 240-3 configuration, which was early, heavy. So, in one way your right, it’s outdated-the range has improved.

    Interestingly, we shall see naval PAK-FA one day, as a part of Project 23000E Shtorm aircraft carrier..
    A combination of CATOBAR and ski-jump ??

    Pipe dream- anyone remember the official claiming the VMF would have four carrier groups by the end of the decade?

    Meanwhile, the project 22350 ships are the largest surface combatants built by Russia in the last 15 years. Not dismissive of Russian capability to design and fund such a project, but there is a hell of a lot of infrastructure and industrial base to regenerate before any 100,000 ton carrier is built.

    The Su-35S..

    If your facing and adversary with good persistance he is not going to be idling around so you can get your fat weezy kid (FWK) into a suitable nice safe firing solution, /B].

    As someone already pointed out…. No to your Su-35 example.

    And be careful there JW that fat wheezy kid has been taking your love child’s lunch money. Seems most Tiffy operators are keen on getting the FWK instead of upgrading the ugly little orphan.

    Three EFT´s and the thing goes to mach 1.8. This is official, right from the mouth of Craig Penrice.
    Or from Christian Worning

    https://openparliament.ca/committees/national-defence/40-3/38/?page=10

    The Norwegian ppt that i have in my pc gives the range in subsonic speed, this doesnt mean that it doesnt go supersonic, it actually goes.

    Cheers

    I see that from the briefing in Canada. So, with the three 1000L tanks, that is confirmed.

    Eurofighter Briefing- http://tmor.rafale.free.fr/Eurofighter_Capability.pdf
    Yeah, the Norway briefing lists the configurations, time, distance, then for each of the load outs lists: max supersonic, supercruise, subsonic. Quite misleading.

    TVIP- bottom of pg.9 top of 10. for the Canadian Parliament link

    The aforementioned typhoon will do it nicely :angel:

    Not according to the briefing by EADS test pilot given in Norway. Three EFT= subsonic
